Many technologies that seemed just around the corner in the 1950s through 2000s turned out to be far more difficult than expected. Here are ten famous examples:
People imagined that by now we’d all be lifting off from our driveways and soaring over traffic. While experimental vehicles exist, they remain expensive, noisy, heavily regulated, and difficult to operate safely.
Science fiction promised robotic butlers capable of cooking, cleaning, folding laundry, and caring for children. We have robot vacuums and increasingly capable AI, but no affordable all-purpose home robot yet.
After the Apollo 11 Moon Landing, many expected permanent lunar colonies by the early 2000s. Instead, humans have not returned to the Moon since 1972, though new missions are underway.
Jetpacks became a symbol of “the future.” Functional versions exist, but they are expensive, noisy, fuel-hungry, and generally unsuitable for everyday travel.
Predictions from the 2010s suggested self-driving cars would be commonplace by now. Significant progress has occurred, but truly universal autonomous driving remains a difficult technical and regulatory challenge.
Many imagined a device that could instantly and perfectly translate any language. Modern AI translation is remarkably good, yet it still struggles with nuance, culture, humor, dialects, and specialized contexts.
Mid-20th-century futurists expected large populations to live beneath the oceans. Building and maintaining underwater habitats has proven far more costly and difficult than anticipated.
Many people expected cancer to be largely defeated by now. Tremendous advances have been made, and survival rates have improved substantially, but cancer is not one disease. It is hundreds of different diseases, making universal cures elusive.
Scientists and futurists once envisioned the ability to steer hurricanes, end droughts, or schedule rain. While cloud seeding exists, reliable large-scale weather control remains beyond current capabilities.
This prediction was actually half right. We do have video calls everywhere, but they did not eliminate business trips, conferences, vacations, or face-to-face meetings as many expected. Human beings remain stubbornly attached to being in the same room together.
A curious pattern appears in these predictions: engineers often underestimate how hard the final 10% is. Building a prototype is one challenge; making it safe, affordable, reliable, legal, and available to billions of people is an entirely different mountain to climb.

Here are 10 practical ways to help your dog live a longer, healthier life:
Obesity is linked to numerous health problems, including arthritis, heart disease, diabetes, and some cancers. Keeping your dog lean is one of the most effective ways to extend both lifespan and quality of life.
Choose a nutritionally complete food appropriate for your dog’s age, size, and health needs. Good nutrition supports everything from immune function to joint health. Dogs are not designed to eat cereal. Their intestines are too short. Real meat is what dogs are designed to eat.
Daily walks, play sessions, and other activities help maintain a healthy weight, strengthen the heart, and keep muscles and joints in better condition.
Regular wellness exams can detect diseases early, often before symptoms become obvious. Early treatment can significantly improve outcomes.
Vaccines, parasite prevention, and heartworm protection help guard against illnesses that can shorten a dog’s life.
Dental disease is extremely common in dogs. Regular brushing, dental chews, and professional cleanings can help prevent infections that may affect other organs.
Dog collars can create long-term muscular-skeletal problems. If you use a halter rather than a collar, all the force that would normally hurt their necks is distributed throughout their upper body. See The Insidious Dog Collar.
Training, puzzle toys, scent games, and learning new commands help keep your dog’s brain active and engaged as they age.
Many common household items can be toxic to dogs, including chocolate, grapes, raisins, xylitol, certain medications, and some houseplants.
Dogs are highly social animals. Positive interaction with people and, when appropriate, other dogs can reduce stress and contribute to overall well-being.
Pay attention to your dog’s usual behavior, appetite, energy level, and bathroom habits. Subtle changes are often the first clues that something needs medical attention. Early detection of illness is one of the most powerful tools for increasing lifespan.
🐕 A simple formula for canine longevity is: healthy weight + regular exercise + preventive veterinary care + a loving home. While genetics play a role, those four factors can have a surprisingly large impact on how long and how well a dog lives.

Here are 10 evidence-based ways to help your cat live a longer, healthier life:
Indoor cats are generally protected from many dangers, including traffic, predators, toxins, diseases, and injuries. Many indoor cats live significantly longer than outdoor cats. The average indoor cat lives 17 years. The average outdoor cat lives 2 years.
Choose nutritionally complete cat food appropriate for your cat’s age and health needs. Good nutrition supports everything from immune function to organ health. Cats are not designed to eat cereal. Their intestines are too short. They do much better with real meat.
Excess weight increases the risk of diabetes, arthritis, heart disease, and other health problems. Measure food portions and avoid excessive treats.
Annual exams, and often twice-yearly exams for senior cats, can catch health issues early when they are easier and less expensive to treat.
Vaccinations help protect cats from potentially serious infectious diseases, especially if they have any exposure to other animals.
Adequate hydration supports kidney function and overall health. Many cats drink more readily from fountains or multiple water stations.
Spaying and neutering can reduce certain cancers and reproductive diseases while also decreasing behaviors that can lead to injury or disease exposure.
Interactive toys, climbing structures, and play sessions help maintain a healthy weight and support cardiovascular and mental health.
Dental disease is common in cats and can contribute to pain, infection, and systemic health problems. Regular dental care can make a meaningful difference.
Cats thrive on routine and a sense of security. Providing hiding places, vertical spaces, predictable schedules, and a calm environment can support both physical and mental well-being.
Learn your cat’s normal habits. Changes in appetite, thirst, weight, grooming, activity level, or litter box use are often among the earliest signs that something may be wrong. Detecting problems early can add both years to your cat’s life and quality to those years.

Native Americans used pumpkin seeds medicinally for centuries, particularly as a treatment for intestinal parasites and kidney problems. Cucurbitin, a unique amino acid in pumpkin seeds, paralyzes tapeworms and other intestinal parasites, causing them to detach from intestinal walls. Folk medicine across multiple cultures independently discovered this.
They are edible at every stage of preparation. They can be eaten raw, roasted, sprouted, or pressed into oil without requiring detoxification or special processing.
Each seed includes a fully formed embryonic plant along with stored nutrients for early growth.
They contain a sleep chemical — pumpkin seeds are one of the best natural sources of tryptophan, the same compound in turkey famously associated with post-Thanksgiving drowsiness.
They have been consumed for thousands of years. Archaeological evidence shows pumpkin seeds were a food source in the Americas long before modern agriculture. Archaeologists discovered pumpkin seeds in caves in Mexico dating back to 7,000–5,500 BCE, making them one of the oldest cultivated foods in the Americas.
Pumpkin seeds contain high levels of magnesium, zinc, iron, and phosphorus compared to many other common seeds.
The hull-less varieties are a cultivated trait. Seeds without shells are the result of selective breeding rather than naturally occurring wild forms.
Pumpkin seed oil contains a high proportion of unsaturated fats and has a strong pigment due to carotenoids and chlorophyll-related compounds.
They remain viable for long periods when dry.
When stored properly, pumpkin seeds can remain capable of germination for multiple years.
They are used in both food and non-food applications.Beyond eating, pumpkin seed oil and extracts are used in cosmetics and traditional herbal preparations.
There is an Austrian “mutant” pumpkin dedicated just to the seeds. In the late 19th century, a natural genetic mutation occurred in the Styria region of Austria. A crop of pumpkins grew with seeds that had absolutely no outer shell. Recognizing a good thing, farmers selectively bred these “naked” seeds. Today, the Styrian oil pumpkin is a highly prized squash grown almost entirely for its dark green, shell-less seeds rather than its flesh.
Unlike most plant proteins, pumpkin seed protein contains a surprisingly complete amino acid profile, making them a rare near-complete plant protein source.
They can be sprouted as a food product. Sprouting changes their nutritional profile and makes some compounds more bioavailable.
Pumpkin seed oil has a bizarre optical illusion built in. If you press those hull-less pumpkin seeds into oil, the resulting liquid exhibits a fascinating optical phenomenon called dichromatism. If you pour a thin layer of pumpkin seed oil onto a white plate or salad, it looks distinctly dark green. However, if you look through a thick layer of it inside a bottle or jar, the oil appears bright, ruby red.
The best part of the shell is the invisible layer. If you do eat the whole, white-shelled seeds from a carving pumpkin, you are getting a massive dose of zinc. However, the highest concentration of that zinc isn’t in the white shell itself, nor is it deep inside the seed. It is actually concentrated in the endosperm envelope—a microscopically thin layer sitting directly between the white shell and the green seed inside.

Neil DeGrasse Tyson keeps a cosmic closet of themed vests, each one a wearable Easter egg for science fans.
He was a championship ballroom dancer. In graduate school, Tyson won a gold medal in a national dance competition in the category of International Latin Ballroom style.
As a teen, he trekked to meet Carl Sagan, who invited him to spend the night during a snowstorm.
He’s been known to fact-check movie physics in real time, like a human director’s commentary that nobody asked for but everyone hears.
He once said if aliens visited, their first impression of Earth would be our nighttime light pollution glow.
When the Hayden Planetarium under his direction grouped Pluto with Kuiper belt objects rather than planets (six years before the IAU officially reclassified it as a dwarf planet), the decision proved controversial and Tyson was deluged with angry letters. He later wrote an entire book about the experience called The Pluto Files.
He collects ties with space motifs.
He attended Harvard but also rowed crew.
He hosted the reboot of Cosmos: A Spacetime Odyssey, stepping into a role once held by his hero, Carl Sagan
He once joked that the universe is under no obligation to make sense to you.
He helped redesign the Hayden Planetarium, making it feel like a spaceship disguised as a museum.
He keeps a meteorite on his desk.
He has strong opinions about whether sci-fi gets gravity right.
At the Bronx High School of Science, Tyson was captain of the wrestling team, and he continued wrestling at Harvard University, where he was also captain of the wrestling team.
He’s written multiple books translating cosmic chaos into human-sized ideas.
He almost became a male exotic dancer. A few of his fellow male dancers began showcasing their skills in Chippendale-like clubs for extra cash, and Tyson, who described himself as “flexible from having danced and pretty cut from having wrestled,” became intrigued. He visited a club to see them perform and said it was only then that he reconsidered and decided to focus on math tutoring instead.
He believes curiosity is a muscle you should exercise daily.
He’s obsessed with precision in language, especially when science is involved.
He’s discussed whether superheroes would survive their own powers. His opinion: often no.
He thinks the scariest thing isn’t aliens, but human misunderstanding of science.
He often reminds people that the atoms in your body were forged in stars.
Neil’s middle name, deGrasse, comes from the maiden name of his paternal grandmother, who was born as Altima de Grasse in the British West Indies island of Nevis.
Tyson’s popularity isn’t only because of his intelligence; he was voted sexiest astrophysicist alive by People Magazine in 2000.


How do we know what animals think or feel? I say be kind to animals just in case it matters to them. The poet William Blake said, “How do you know but that every bird that cleaves the aerial way is not an immense world of delight closed to your senses five?”
Your author believes that it is easy to dismiss animals as not having much of an emotional or intelligent life. After all, they haven’t learned language. But does that mean they can’t think? Not at all. For instance, years ago, I was learning some rollerblading moves. One was a single spin jump. In bare feet at home, I was practicing by jumping in the air, spinning 360 degrees around and landing. My cat watched for a moment, then walked around in a 360 degree circle. Should that be dismissed as somehow incidental?

What do you call a snowman who’s always asking questions? A Snow-it-all.
A snowstorm knocked out my Wi-Fi, and for a moment I wanted to pretend I was one of those rugged outdoorsy types. Then I remembered rugged people don’t cry when Netflix stops buffering.
I told my friend I slipped on the ice yesterday. He said, “That’s what happens when you try to skate without skates.” I said, “No, that’s what happens when you try to walk with dignity.”
What did the icy sidewalk say to the pedestrian?
“Slip happens.”
A snowman applied for a job. The interviewer asked, “What’s your greatest strength?” The snowman said, “I’m outstanding in my field.”
I saw a squirrel digging in the snow, and it looked at me like it knew I wasn’t prepared for winter either. We shared a moment of mutual panic before it scampered off to judge someone else.
I made a cup of hot chocolate, and for six glorious minutes, everything was perfect.
Then I stood up, spilled half of it on my socks, and remembered who I truly am.
The snowplow left a four-foot snow wall at the end of my driveway. I’m considering turning it into a castle and declaring independence from the rest of the neighborhood.
I tried to jog in the cold, but after two minutes my lungs sounded like creaky door hinges. I decided fitness could wait until April or possibly 2047.
I asked the ski instructor if I was improving. He said I was going downhill fast.
I bought one of those hand warmers, and now I rely on it more emotionally than physically.
It’s the closest thing to a supportive relationship I’ve had all winter.
My mailbox froze shut, which honestly feels like the universe protecting me from bills.
Winter is harsh, but sometimes it’s merciful.
My neighbor spent three hours building an elaborate snowman family in his front yard – a dad, mom, two kids, even a snow dog. That night it rained and the next morning they were just puddles. His actual family came outside, looked at the yard, and his wife said, “Well, that’s basically what happens to all families eventually.” He hasn’t built a snowman since.
My neighbor bragged about loving the cold, which is suspicious behavior in my opinion.
No one should be that excited about weather that hurts your face.
How does a snowman flirt? He gives you the cold shoulder… then warms up with a hug.
I went to a winter survivalist training course last year. The instructor kept saying “there’s no such thing as bad weather, only bad clothing.” So on the last day, I showed up in a Hawaiian shirt and flip-flops. Turns out there is such a thing as bad students, and I was no longer welcome.
My wife opens the bedroom window every winter “just a crack” for fresh air.
When I asked why we can’t close it, she said, “Cold air improves sleep quality.”
I said, “Does it also improve marriage quality? Because right now I’m spooning the radiator.”
I decided to start winter bird watching as a hobby. Spent $200 on binoculars, a guide book, and warm gear. Went out every morning for a week. Saw exactly three pigeons and a plastic bag that I followed for ten minutes thinking it was a rare bird.
My gym has a sauna, and in winter the parking lot becomes this bizarre social experiment. People sprint from their cars in tank tops and shorts through sub-zero temperatures to get to the sauna. We’re literally running through winter to sit in artificial summer. Evolution did not prepare us for this level of irony.
My car’s “winter emergency kit” that I put together in November is basically just a confession that I’ve given up. There’s a blanket, some granola bars, a flashlight with dead batteries, and a note that says “I’m sorry” to whoever finds me. My wife found it and said, “This is the most ‘you’ thing I’ve ever seen.” Not sure how to take that.
Every year I tell myself I’m going to embrace winter and try a new snow sport. Last year I tried snowshoeing. I made it about 200 feet before I realized I was just walking slowly while looking ridiculous.
I signed up for a winter photography class to take beautiful pictures of snow-covered landscapes. The instructor kept talking about “golden hour” and “perfect light conditions.” I waited outside in -15 degree weather for golden hour. My phone died in three minutes. My regular camera froze. I got one blurry photo of my own breath. The instructor said it had “interesting texture.” I think he was being kind.
I tried making snow ice cream with my kids like my grandmother used to make. We gathered fresh snow, added vanilla and sugar, and it tasted like frozen sadness and car exhaust. Turns out snow in the suburbs isn’t the same as snow on my grandmother’s farm in 1950. My kids asked if we could just have regular ice cream. Even they know when to quit. But I ate mine anyway out of principle. The principle of poor decision-making.

The officer asked, “Do you know how fast you were going?” Neil said, “I have a general idea, but according to Heisenberg’s Uncertainty Principle, the more accurately I measure my momentum, the less accurately I know my position relative to the patrol car.”
A movie producer told Neil he wanted to make a sci-fi film where a spaceship travels faster than light. Neil said, “I’m sorry, I can only consult on movies where the physics are merely implausible, not fundamentally incorrect.”
I asked Neil deGrasse Tyson what his least favorite planet was. He said, “Pluto. Just kidding, I find its reclassification as a ‘dwarf planet’ perfectly defensible based on its orbit and mass ratio.” (He then smiled very slightly.)

I was wondering whether the current generation of chatbots can be used for original research which would involve intelligently gathering data from across the web, then applying math in appropriate ways to determine a result.
As you can see in the example below, ChatGPT more than excelled in this process.
Of course there are some caveats:
a. We haven’t verified whether the original sources for this information are accurate.
b. We don’t know whether the AI may have hallucinated.
c. This particular example is rather simplistic. People reading this report might go on to assume that humans on a vegetarian diet will therefore outlive carnivorous or omnivorous humans. Perhaps the variance in lifespan is about chemical processes involving animal protein. However, this very simple research doesn’t take into considerations such as that carnivores have to move more and take more risks to get their food than herbivores.
So, without further ado, I asked an AI chatbot (ChatGPT):
“Can you make a chart with an assortment of animals, showing whether vegetarians or carnivores average longer lives?”
Sure! Here’s a clear, data-informed chart comparing average lifespans of selected herbivores (vegetarians) and carnivores, with examples from similar habitats and sizes where possible.
| Category | Animal | Diet Type | Average Lifespan (years) | Notes |
|---|---|---|---|---|
| Mammal | Elephant | Herbivore | 60–70 | One of the longest-living land animals. |
| Mammal | Horse | Herbivore | 25–30 | Lifespan depends on breed and care. |
| Mammal | Cow | Herbivore | 18–22 | Domesticated; wild relatives live shorter. |
| Mammal | Rabbit | Herbivore | 8–12 | Prey species; shorter lifespan. |
| Mammal | Human | Omnivore (mostly herbivorous tendencies) | 72–83 | Diet has major influence. |
| Mammal | Lion | Carnivore | 10–14 | Shorter in wild due to conflict and disease. |
| Mammal | Tiger | Carnivore | 10–15 | Captivity increases to ~20. |
| Mammal | Dog (wolf) | Carnivore/Omnivore | 6–13 (wild: 6–8) | Domesticated breeds vary widely. |
| Mammal | Cat (wildcat) | Carnivore | 6–15 | Domesticated cats live longer (12–18). |
| Bird | Parrot (Macaw) | Herbivore (fruits, nuts) | 50–80 | Extremely long-lived bird. |
| Bird | Eagle | Carnivore | 20–30 | Top predator; lifespan limited by competition. |
| Reptile | Tortoise | Herbivore | 80–150+ | Among longest-lived animals on Earth. |
| Reptile | Crocodile | Carnivore | 60–80 | One of the longer-living carnivores. |
| Fish | Carp (Koi) | Herbivore/omnivore | 25–70+ | Some live over a century. |
| Fish | Shark (Great White) | Carnivore | 30–70 | Greenland shark can exceed 250 years (!). |
Herbivores (vegetarians) often live longer on average, especially large and slow-metabolism species (elephants, tortoises, parrots).
Carnivores tend to have shorter lifespans, partly due to higher metabolic stress, riskier lifestyles, and territorial aggression.
Exceptions: Some long-lived carnivores exist (e.g., Greenland shark, crocodile), usually cold-blooded or slow-metabolism species.
Among mammals, herbivores generally edge out carnivores in lifespan when other factors (size, metabolism, environment) are similar.
Among mammals, herbivores generally edge out carnivores in lifespan when other factors (size, metabolism, environment) are similar.

Marie Curie was not just a scientist, she was a revolution in human form. Born Maria Salomea Skłodowska in Warsaw, Poland, on November 7, 1867, she would go on to become the first woman to win a Nobel Prize, the only person to win Nobel Prizes in two different scientific fields, and one of the most influential figures in science history. Her story is not only one of intellect and perseverance, but also of danger, love, tragedy, and even a touch of radioactive oddity.
Marie was the youngest of five children in a family of educators. Her father taught math and physics, and her mother was a headmistress, but life in Poland under Russian occupation was hard. After losing her mother to tuberculosis at age 10 and her sister to typhus, young Maria grew up in a world shaped by hardship and intellectual rebellion.
Women were not allowed to attend university in Russian-ruled Poland, so Maria became involved in the Flying University, an underground network of classes for women. She worked as a governess to support herself and save money for further education. During this time, she fell in love with a Polish mathematician, Kazimierz Żorawski, but his aristocratic parents forbade the match. Heartbroken but undeterred, she eventually made her way to Paris in 1891, where she adopted the French version of her name: Marie.
In Paris, Curie enrolled at the Sorbonne, where she lived on little more than tea and bread, often fainting from hunger but finishing at the top of her class in physics in 1893, and mathematics in 1894.
That same year, she met Pierre Curie, a fellow scientist who recognized her brilliance. The two married in 1895, bonding over science and shared idealism. Rather than a diamond ring, Pierre gave Marie a bicycle, which they used on their rustic honeymoon, an unusual but fitting symbol of their egalitarian and unconventional union.
Marie began studying uranium, inspired by the recent discovery of X-rays and Henri Becquerel’s work on radioactive properties. She coined the term “radioactivity,” and, in her meticulous research, discovered two new radioactive elements: polonium (named after her beloved Poland) and radium (from the Latin radius, meaning “ray”).
In a time when lab work was laborious and unglamorous, Marie and Pierre processed tons of pitchblende (a uranium-rich ore) by hand, boiling it down in an abandoned shed with no ventilation. The Curies often worked without gloves or protective gear, unknowingly exposing themselves to dangerous radiation.
Fun fact: Marie Curie’s notebooks are still radioactive—over a century later, they are kept in lead-lined boxes at the Bibliothèque nationale de France. Visitors must sign waivers and wear protective gear to consult them.
In 1903, Marie and Pierre Curie, along with Henri Becquerel, were awarded the Nobel Prize in Physics—making Marie the first woman to win a Nobel. At first, the Nobel committee intended to honor only Pierre and Becquerel, but Pierre insisted that Marie be credited as an equal contributor. Her scientific merit, not her gender, deserved the spotlight.
Tragedy struck in 1906 when Pierre was killed in a street accident, run over by a horse-drawn carriage. Marie was devastated but persevered. In an almost unheard-of move for a woman at the time, she was offered and accepted Pierre’s professorship at the Sorbonne, becoming the first female professor in the university’s history.
In 1911, she received her second Nobel Prize, this time in Chemistry, for her discovery and isolation of radium and polonium. This remains an unmatched achievement: no other person has won Nobel Prizes in two scientific disciplines.
Curie’s discoveries triggered a bizarre public fascination with radium. People believed it had mystical healing properties. It was added to cosmetics, toothpaste, water, and even radium-laced chocolate bars. There were “glow-in-the-dark” parties, and one company sold a product called Radithor, essentially radium in water, promoted as a cure-all.
One tragic result was the case of the “Radium Girls.” They were young women who painted watch dials with luminous radium paint and were encouraged to lick their brushes to keep the tips fine. Many died of radiation poisoning.
Ironically, while Marie Curie remained skeptical of commercialized radium, she carried test tubes of it in her pocket for experiments. Her clothes reportedly glowed faintly in the dark.
During World War I, Curie saw a practical use for her discoveries. She developed mobile X-ray units called “Little Curies” and trained medical staff to operate them. These vehicles saved countless lives by helping battlefield doctors locate shrapnel and broken bones.
She even drove one of these X-ray cars herself to the front lines, without a driver’s license or formal medical training. That was a gutsy move for any woman, let alone a Nobel-winning physicist.
Curie spent her later years founding the Radium Institute (now Curie Institute) in Paris, a world-class center for medical research. Her health, however, deteriorated from long-term exposure to radiation. She died in 1934 at the age of 66, of aplastic anemia, a condition linked to radiation exposure. At the time, the dangers of radioactivity were still poorly understood.
Despite the risks, she never patented her discoveries, believing that science should benefit humanity. “Radium is not to enrich anyone. It is an element. It belongs to all people.”
In 1995, Marie and Pierre Curie’s remains were transferred to the Panthéon in Paris—France’s national mausoleum for heroes. Marie became the first woman to be entombed there based on her own merits.
Marie Curie’s legacy goes far beyond the laboratory. She broke gender barriers, challenged academic norms, and fundamentally changed our understanding of matter and energy. She inspired generations of scientists, especially women in STEM fields, by proving that brilliance knows no gender.
She refused medals and awards in her later years, believing the work mattered more than the recognition.
She carried out much of her work in a wooden shed with a leaky roof and no insulation, describing the conditions as “a cross between a stable and a potato cellar.”
Albert Einstein once said of her, “Marie Curie is, of all celebrated beings, the only one whom fame has not corrupted.”

In my youth, my dad gave me a catalog from a supplier of scientific equipment. It used to be called Ward’s Natural Science Establishment. Their website is Wardsci.com. He let me buy things from the catalog from time to time. I started with some things like flasks and microscope slides. I was rapidly turning into a happy science nerd.
I noticed they had a little kit to make something called “Bio-Plastic Mounts.” With that little kit, I could take specimens such as bugs, coins, or postage stamps and embed them in clear plastic blocks. I fooled around with it for a while, then moved on to other pursuits.
What I’m thinking now is that embedding things in clear plastic could be a great business for someone. So far as I know, it’s not being offered anywhere.
Imagine, a client could send you an important keepsake, maybe a four-leaf clover, or a snapshot, or a scientific specimen, or a special coin. You embed it in plastic, and charge a lot of money!
Now there will be some difficulties to overcome. First, so far as I can tell, Ward’s no longer sells the kit. All they have is the bio-plastic material, a two-part liquid that hardens. The kit contained a mold, some of the liquid plastic, and mold release compound, plus some miscellaneous brushes and such, as I recall.
The procedure was to prepare the specimen. It had to be dry. I found out early on that any liquid would leak out and contaminate the mount. Then, I’d coat the mold with release compound, mix up some of the plastic liquid, and fill the mold about a third of the way. Shining an incandescent lightbulb on the mold, I let the plastic layer harden overnight. Then I’d set the specimen on that layer of hardened plastic, and fill the remaining two thirds of the mold with plastic. Once the plastic was hardened, I’d snap it out of the mold.
You’d think that would be it, but no, the work was just beginning. The surfaces of the mount were rough and not entirely transparent. Each surface had to be sanded until there were no bumps or depressions, then sanded and polished with ever finer grits until it became fully transparent. I did it by hand, and by the time I was done, the edges were often rounded. If I had a belt sander, my mounts would have been finished much faster, and come out much better.
No doubt you could improve on the process. There may be molds that you can acquire or make that leave a smooth enough finish that sanding and polishing is not required. There may be another, better source of plastic. I remember how stinky the stuff was. Perhaps Ward’s discontinued it because it was toxic.
If you can work out a nice process, you’d have a very nice home business on your hands! You could make mounts of things like four-leaf clovers (that you can buy on Ebay) and sell them locally such as at flea markets, or online through Ebay, Etsy or Amazon. You could let people know they can send their keepsakes or specimens to you for embedding. You would have to be practiced and careful, because you don’t want to wreck things that could be very important to your clients. But, you could charge a heck of a lot of money for a mount, right?
Taking the concept a step further, one could make coffee tables and other large things with embedded specimens in plastic.

If you know quite a bit about cats you could be a cat whisperer. No license and no certification is necessary in most communities. It helps to understand their mentality, the reasoning behind the things they do, and the ways they are likely to react to various situations. Perhaps just as important, if you know something about people, and especially how they interact with their pets, you’ll have a big advantage.
Hang out your shingle, and you can do housecalls, helping people with their cats.
Your technique doesn’t much matter. You might offer the cat treats, you might talk to the kitty, you might wave a wand. Hopefully, your technique will correct cats’ behavior, or the cats’ owners’ behavior in a majority of the cases, but even if it doesn’t, and you certainly don’t want to guarantee it, you can charge your clients a surprising amount of money.
I’d launch a business like this on Craigslist, or any community website that serves your area. Have a nice personality. Tell all your clients how much you appreciate them talking you up to their friends and relatives. You’ll be amazed that even when the kitty’s behavior doesn’t change, they’ll still recommend you. Crazy, but true. However, I recommend being 100% legitimate. You really do want to do your best to help these kittycats, and their people.
By the way, it will probably more often be the people’s behavior that you’ll want to change, not the cats.
Here are a couple of tricks you may find useful:
If two cats don’t get along, put a drop of perfume on their backs. The cats will smell just like each other, and they’ll think of each other as family. This can have an immediate effect.
If you’re trying to slow a busy cat, lift up slightly on the scruff of the neck. This lifting mimics what the mother cat does to carry kittens, and it sets off a reflex that causes the cat to immediately stop wiggling or resisting. You don’t need to lift the cat entirely off its feet. In fact lifting an adult cat in the air by the scruff might hurt the kitty.
An older male cat that starts urinating in bad places is probably suffering from urinary tract problems. I don’t know if it’s too late to help, but I highly recommend changing the diet right away if the cat has been eating solid cereal-like food all it’s life. Cats are meat-eaters, with a short intestine appropriate for a carnivorous diet. Giving them the wrong kind of food, even if the companies that make it insist it’s alright, can result in urinary problems, and probably other medical issues as well.
A cat that doesn’t want to be picked up is probably suffering from early memories of being held captive. Have the owner pick up the cat a few times a day, but set the cat back down right away, or as soon as the cat starts wiggling. In time, the cat will realize that it’s not being held captive, and may learn to love the warm attention.
A cat that scratches furniture will stop immediately if the furniture is covered in aluminum foil. They also won’t walk on aluminum foil, so that’s a good way to protect things like half-done picture puzzles.
Is a cat too playful with it’s claws? Are the owners getting scratched? Whenever the owners can, as they play with their kitties, have them gently press the kitty’s claws back into a retracted position, and hold them that way for several seconds. It may take a while, but eventually the cat will play better. Under no circumstances should a cat be declawed. It makes them miserable for weeks afterward, and leaves them unprotected if they have to deal with predators outside the home.
Avoid any sounds that sound like hissing. This upsets cats. They may not show it, but even mild hissing noises can set them off into bad behavior.
What do you do with a cat that stays under the furniture and hisses at anyone who comes by? First, put the cat’s food and toilet where it can be reached without undue exposure. Cat’s in fear worry about attacks from overhead, like big birds coming out of the sky. So they like to stay under things. People can, and should be in the same room with the cat. Let the cat get used to people all around. Don’t try to make friends with the cat. Don’t stare at the cat, and try to make the kitty come out and be your friend. Same with some dogs and cats. As long as the other animals in the room don’t attack or tease the cat, the kitty will slowly get used to the environment, and venture out from under cover a little more each day.
How to give medicine to a cat: If it’s liquid, put it on the kitty’s back. The cat will lick it off. If the cat needs pills, one of the best techniques is used by veterinarians: They quickly wrap the cat in a towel, so the cat cannot scratch, and cannot wiggle away. That seems terrible, but it’s less traumatic than a long battle. Another thing about the towel that’s interesting: Many animals, and sometimes people too, like being gently squeezed in a restricted space. It calms them. In cattle ranching, they have a thing called a “squeeze frame,” in which a cow is placed. It keeps the cow calm while medical procedures are administered.

🦵 Anatomy & Function
The knee is the largest joint in the human body, acting like a hinge and a pivot at the same time.
The patella (kneecap) is a sesamoid bone—a bone embedded within a tendon, which is quite rare.
Your knee joint contains synovial fluid, which has a similar viscosity to egg whites and reduces friction between the bones.
Three bones meet at the knee: the femur (thigh), tibia (shin), and patella (kneecap)—but they don’t all touch each other directly.
The menisci (two C-shaped cartilage pads) act like shock absorbers, helping your knee withstand about 3-6 times your body weight during activities like climbing stairs.
🦴 Biomechanics
Knees are not symmetrical—the alignment and shape vary from left to right and person to person.
While they mostly act as hinges, knees actually have a slight rotational capability, especially when flexed.
During walking, each knee bends and straightens about 1,500 times per mile.
Knees absorb more stress than your hips when you run, especially downhill.
The posterior cruciate ligament (PCL) is so strong it’s often injured only in car crashes or serious falls.
🧬 Evolutionary/Ethnographic Facts
Human knees evolved from the knees of four-legged animals, which is why they’re structurally complex and sometimes prone to failure.
In some populations (like the Bajau people, who free-dive), knee joint flexibility is enhanced from constant squatting and treading water.
Babies are born with no hard kneecaps—just cartilage that ossifies (turns to bone) over the first few years.
Some ancient humans, such as Neanderthals, had knees that bent slightly differently, possibly to support heavier bodies.
Knees are part of what makes human bipedalism efficient—chimpanzees have straighter hips and bent knees, making their walking awkward and energy-inefficient.
🏥 Injuries & Disorders
The ACL (anterior cruciate ligament) is one of the most commonly torn ligaments in sports.
Women are 2 to 8 times more likely to tear an ACL than men—due to biomechanics and hormonal differences.
“Runner’s knee” is a vague but common term—often used to describe pain from patellofemoral syndrome.
Some people are born with double-jointed knees, making them hyperextend in strange directions.
Osgood-Schlatter disease, a common adolescent condition, causes swelling just below the kneecap from overuse during growth spurts.
😲 Weird & Curious
Knee popping or cracking sounds (called “crepitus”) are usually harmless, though they can sound intense.
The term “knee-jerk reaction” comes from a real neurological test—when a doctor taps your patellar tendon, your leg reflexively kicks.
In medieval duels, knights often aimed below the belt to strike weak points like the knee.
Some Buddhist monks stand or kneel for hours daily, and have developed thickened knee skin and joint adaptations.
There’s a rare condition called patella alta, where the kneecap rides unusually high on the femur.
🧠 Cultural, Linguistic & Symbolic
Kneeling is a universal symbol of submission or respect—from marriage proposals to religious rituals.
The knee was once considered erotic—Victorian women covered theirs at all times, even when bathing.
The phrase “on bended knee” first appeared in 15th-century English literature, long before Boyz II Men sang about it.
Some martial arts train fighters to deliver devastating knee strikes, which can produce more force than punches.
In yoga and meditation traditions, knee pain is common in seated poses, but ancient texts rarely mention it—possibly due to lifestyle differences and more flexible knees back then.

They use tools – Chimpanzees make and use tools like sticks to fish termites, rocks to crack nuts, and leaves as sponges.
They plan ahead – Chimps have been observed saving tools for future use, indicating forethought.
They learn sign language – Some have been taught over 200 signs in American Sign Language.
They understand fairness – Chimps can become upset if they feel another chimp gets a better reward for the same task.
They self-medicate – Chimps eat specific bitter plants to treat parasitic infections.
They mourn the dead – Groups will gather silently around a deceased chimp and even stroke or groom the body.
They recognize themselves in mirrors – This shows self-awareness, a rare trait among animals.
They can deceive – Chimps sometimes hide food or pretend not to know something to manipulate others.
They share 98.8% of human DNA. We are closer to chimps than rats are to mice.
They can catch human diseases including colds, flu, and even Ebola.
They have better short-term memory than humans – In memory tests, some young chimps outperform adult humans.
They can go bald. Like humans, some chimps experience hair loss with age.
They have individual fingerprints. Just like humans, every chimp has unique finger and toe prints.
They walk on knuckles – But can also walk upright for short distances.
They form lifelong friendships. Especially males, who build strong social bonds.
They go to war. Troops of chimps have been seen planning and executing raids on rival groups.
They patrol borders. Male chimps guard territory and will attack outsiders.
They have power struggles. Alpha males are challenged and overthrown, often through coalitions.
Females use politics too. Female chimps sometimes form alliances to resist domineering males.
They hunt and eat meat – Chimps have been seen hunting monkeys and sharing the meat.
They pass down traditions. Tool use, foraging styles, and gestures vary by group, much like human cultures.
They love ripe fruit. Bananas, figs, and mangoes are favorites, but they’ll also eat insects and eggs.
They chew leaves to make “green tea” for digestion or detoxification.
They have long childhoods. Young chimps stay with their mothers up to 7 years.
They play with dolls. Young females sometimes carry sticks or logs as if they were infants.
They share food with infants. Often gently and deliberately.
They’re endangered, mostly due to habitat loss and poaching for bushmeat.
“Ham” the chimp flew into space on a Mercury mission in 1961.
They’ve worn fashion. Some wild chimps have been spotted wearing grass “accessories” for no practical reason, possibly as fashion or display!
They can learn from watching TV. Chimps have been known to imitate actions they see on screen.

Owls have eyeballs shaped like tubes, not spheres. This means they can’t move their eyes—so they rotate their heads instead.
They can rotate their heads up to 270 degrees thanks to 14 neck vertebrae (humans have 7).
Owls’ ears are asymmetrical. One is higher than the other, allowing pinpoint accuracy in locating prey by sound.
They have feathered legs. Some owl species have fluffy feathers all the way down to their talons.
An owl’s face works like a satellite dish, funneling sound to its ears.
Their eyes are bigger than their brains. In many owl species, the eyes take up most of the skull.
They have three eyelids per eye: one for blinking, one for sleeping, and one for cleaning.
Owls have zygodactyl feet, meaning two toes point forward and two backward—perfect for grasping prey.
Owls’ bones are incredibly light and full of air. That helps with silent flight—but it also means their skeletons are fragile.
They don’t have a crop. Unlike many birds, owls don’t store food in a separate pouch—it goes straight to the stomach.
Owls swallow prey whole, then regurgitate indigestible parts like bones and fur in compact pellets.
Owl pellets are used in school biology classes to study animal anatomy, because they often contain nearly complete skeletons.
They can hear a mouse under a foot of snow.
Some owls have been known to use tools, like using sticks or bait to lure prey.
Not all owls are nocturnal. Some, like the Northern Hawk Owl, hunt during the day.
Owls are mostly solitary. Some pair up for life, but most are extremely territorial and antisocial.
Owls are silent killers. Their specialized wing feathers muffle sound so they can sneak up on prey undetected.
They can fly inches from your ear and you won’t hear it.
Young owls “branch” before flying. They climb and hop between branches before learning to fly.
Owlets sometimes hiss or scream like a snake to scare away predators.
There are over 250 species of owls found on every continent except Antarctica.
The Elf Owl is the smallest owl—only 5 inches (12.7 cm) tall and weighs less than a golf ball.
The Blakiston’s Fish Owl is the largest owl, with a 6-foot (2 meter) wingspan.
Owls nest in surprising places— including cactus holes, termite mounds, and abandoned vehicles.
The Barn Owl has one of the most eerie calls, a screech, not a hoot.
Ancient Romans believed owls were omens of death.
Owls can play dead when cornered. The Japanese Scops Owl flattens its body to look like a tree branch.
In some African cultures, owls are considered witches in disguise.
Owls are illegal to keep as pets in the U.S. without special licenses, despite their portrayal in pop culture.
Owls have been trained for falconry, though they’re generally too stubborn and independent to be reliable.
