7 amazing inventions discovered by mistake
- Some of these things have been around for nearly 200 years.
- All were "discovered" by accident.
- The term "Eureka!" actually became the state motto of California during the gold rush.
There are times when a researcher, scientist, or just a common, everyday tinkerer accidentally makes something that wasn't quite what she or he had in mind, but ends up leading to an invention that becomes ubiquitous across the world.
Here are seven "fortunate accidents" in science and the iconic items that came out because of them:
1. The Pacemaker

"I'm beginning to think I may not change the world, but I'm still trying," Wilson Greatbatch, Inventor, 2007.
In fact, Mr. Greatbatch had indeed changed the world, after having invented a device by mistake that would save the lives of millions of people.
He'd been working on a device to record the rhythm of a human heartbeat. In 1956, as he was trying to finish the circuit where he worked at the University of Buffalo as an assistant professor, he accidentally grabbed the wrong sized resistor and used it instead. This was one of those "fortuitous" accidents, as it turned out. The intermittent electrical impulses that the device created because of that final resistor were very much like the sounds of a human heartbeat.
Seeing the value of such a device, he immediately set to work trying to make it small enough to fit inside a human. There were other research labs doing the same, so he worked urgently to get it done — documented in the book he wrote about the experience, The Making of the Pacemaker. His 2-inch device was debuted in testing on dogs in 1958 at the Buffalo Veterans Administration, and eventually, his device was licensed by Medtronic, and the rest, as they say, is history.
Greatbatch, seeing the biggest limitation of his pacemaker device hinge on the 2-year battery life, later acquired the rights to a lithium iodide battery, which would make his design last 10 years or more, and he redesigned it — the original version was potentially "explosive" — and later, his redesigned battery was adapted in countless medical devices, and still is.
2. Corn Flakes

The Kellogg brothers — John and Will — both worked in a Battle Creek, Michigan, sanitarium (what they used to call long-term care). In fact, John was physician-in-chief.
Their religion, Seventh-Day Adventist, preached vegetarianism and avoidance of alcohol as central concepts; as such, the Kellogg brothers sought to find ways to help patients through nutrition.
That's why they had some dough on hand one day, made up of whole wheat, and accidentally let it dry too much. When that dried mixture was in the process of being flattened, it separated into pieces, or flakes. Like they always did with their doughs and bread mixtures, they heated that in an oven to see what would happen.
A few years later, the base was changed to corn from wheat, and Corn Flakes were born.
3. Microwave Ovens

Since they were accidentally invented in about 1945 these devices have changed the way we live.
(Flashback to my college days... after chugging down too many beers at the local bar where bodies were squeezed into tiny spaces and conversations were always shouted into ears, we'd always hit the 7-Eleven and get cheaply-made microwaved burritos. They didn't suck. Good times.)
But I digress.
Percy L. Spencer, widely known as an electronics genius after his stint in the Navy in WWI, was working for Raytheon in 1939, and his ideas and knowledge about radar helped the company win a government contract to develop the new technology and deploy it as "combat radar." Especially as WWII was on the horizon, this was actually the second highest priority project for the military only after the Manhattan Project.
Radar arrays use magnetrons — invisible, super-energetic, short-wavelength radio waves that travel at the speed of light — to function, and while testing radar equipment that had such, Spencer felt a strange sensation in his pants.
Specifically, a chocolate bar had melted when exposed to the waves created. He tested other foods, and when he discovered that the waves could pop popcorn all on their own, that was it.
Being the smart man he was, he quickly figured out how to create, patent, and then bring to market his invention. They began life as very large and costly devices, only being used on ships, trains, and in some restaurants; it wasn't until 1967 that the first commercial microwave was made successfully for home use.
The rest is... convenient and delicious.
4. Recreational LSD — Lysergic Acid Diethylamide
Alice In Wonderland, tripping heavily.
From Dazed.com, "Your Guide To A Safe Acid Trip"
On November 16, 1938, Swiss chemist Albert Hofmann was attempting to create an analeptic compound to help people coming out of anesthesia, which also could potentially help premature infants keep breathing properly.
To get there, he attempted to combine the stimulant diethylamide with lysergic acid. Having failed, the experiment was set aside for 5 years.
The next time he returned to it on April 16, 1943. After creating the combination of the two, he accidentally ingested some, probably from a careless fingertip. He described the resultant sensations as being in his journal:
"... affected by a remarkable restlessness, combined with a slight dizziness. At home I lay down and sank into a not unpleasant intoxicated-like condition, characterized by an extremely stimulated imagination. In a dreamlike state, with eyes closed (I found the daylight to be unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors. After some two hours this condition faded away."
Three days later, he dosed himself for an experiment with 250 micrograms of the material, in what forever will be known as Bicycle Day because the trip began while he was riding a bike home. He then freaked out, thought he was dying, summoned a doctor — who, shaking his head after hearing what he'd done, told him he couldn't help him — and then Hofmann finally settled in for a really pleasant trip and felt wonderful the next day. Also from his journal:
"I could begin to enjoy the unprecedented colors and plays of shapes that persisted behind my closed eyes. Kaleidoscopic, fantastic images surged in on me, alternating, variegated, opening and then closing themselves in circles and spirals, exploding in colored fountains, rearranging and hybridizing themselves in constant flux. It was particularly remarkable how every acoustic perception, such as the sound of a door handle or a passing automobile, became transformed into optical perceptions. Every sound generated a vividly changing image, with its own consistent form and color."

Up until the fairly recent past, many inventions — both accidental and purposeful — created by women were stolen. That, or the role women played in the thing's creation was downplayed into oblivion.
Not so with Stephanie Kwolek, a chemist at DuPont. In 1965, after being asked by DuPont to create the "next generation" of fibers, she began attempting to create a material that would form stronger, lighter tires for use on vehicles.
She came across something that was lightweight, yet 5 times the strength of steel, and eventually, went on to create Kevlar.
The fibers have saved countless lives since then, in law enforcement, the military, and other places. And variations of it have gone on to be used for suspension bridges, to surround the underground fiber optic internet cables that connect the world, and so many other innovative projects.

Life before penicillin was much more brutal, deadly, and painful. Everything from pneumonia to rheumatic fever to gonorrhea all the way to blood infections and simple cuts that would lead to gangrene.
In 1928, penicillin was discovered — by Sir Alexander Fleming, a chemist and inventor who was, ironically, trying to create a miracle drug. The petri dish that the first discovered penicillin mold grew in was in a dish that had been left uncovered after other experiments had taken place using Staphylococcus aureus bacterium.
What he found was a ring of mold growth that had apparently killed the staph bacterium. Isolating the new discovery, however, and producing it in mass quantities, took until 1939, just before World War II.
7. Potato Chips
The box that eventually became standard. From OriginalSaratogaChips.com
There are a few different accounts of how potato chips were invented. There are even references to similar edible delights in cookbooks going back to the early 1800s.
But they became popular in upstate New York, near a town called Saratoga Springs, beginning in 1853.
A famous cook at Moons Lake House, George Speck, eventually to be known as George Crum, is said to have invented them one evening when a wealthy patron sent back the mushy slices of potatoes that he first made in exchange for something thinner cut. When the patron sent them back again, Crum sliced them incredibly thin and then fried them in oil and sprinkled salt on them afterward.
The gentleman love them and ordered more. Seven years later, "Saratoga Chips" were all the rage at both that restaurant and the new restaurant that George Crum founded, appropriately named Crums. He would serve them in boxes, and allow guests to take them homes as well.
George's sister, Katie Wicks, claimed after he passed that she was the one that invented them, from accidentally knocking a thin slice of potato into the deep fryer and then trying it out.
Whichever you believe, this accidental invention soon became the top-selling snack of all time across the United States.

Richard Feynman once asked a silly question. Two MIT students just answered it.
Here's a fun experiment to try. Go to your pantry and see if you have a box of spaghetti. If you do, take out a noodle. Grab both ends of it and bend it until it breaks in half. How many pieces did it break into? If you got two large pieces and at least one small piece you're not alone.
But science loves a good challenge<p>The mystery remained unsolved until 2005, when French scientists <a href="http://www.lmm.jussieu.fr/~audoly/" target="_blank">Basile Audoly</a> and <a href="http://www.lmm.jussieu.fr/~neukirch/" target="_blank">Sebastien Neukirch </a>won an <a href="https://www.improbable.com/ig/" target="_blank">Ig Nobel Prize</a>, an award given to scientists for real work which is of a less serious nature than the discoveries that win Nobel prizes, for finally determining why this happens. <a href="http://www.lmm.jussieu.fr/spaghetti/audoly_neukirch_fragmentation.pdf" target="_blank">Their paper describing the effect is wonderfully funny to read</a>, as it takes such a banal issue so seriously. </p><p>They demonstrated that when a rod is bent past a certain point, such as when spaghetti is snapped in half by bending it at the ends, a "snapback effect" is created. This causes energy to reverberate from the initial break to other parts of the rod, often leading to a second break elsewhere.</p><p>While this settled the issue of <em>why </em>spaghetti noodles break into three or more pieces, it didn't establish if they always had to break this way. The question of if the snapback could be regulated remained unsettled.</p>
Physicists, being themselves, immediately wanted to try and break pasta into two pieces using this info<p><a href="https://roheiss.wordpress.com/fun/" target="_blank">Ronald Heisser</a> and <a href="https://math.mit.edu/directory/profile.php?pid=1787" target="_blank">Vishal Patil</a>, two graduate students currently at Cornell and MIT respectively, read about Feynman's night of noodle snapping in class and were inspired to try and find what could be done to make sure the pasta always broke in two.</p><p><a href="http://news.mit.edu/2018/mit-mathematicians-solve-age-old-spaghetti-mystery-0813" target="_blank">By placing the noodles in a special machine</a> built for the task and recording the bending with a high-powered camera, the young scientists were able to observe in extreme detail exactly what each change in their snapping method did to the pasta. After breaking more than 500 noodles, they found the solution.</p>
The apparatus the MIT researchers built specifically for the task of snapping hundreds of spaghetti sticks.

What possible application could this have?<p>The snapback effect is not limited to uncooked pasta noodles and can be applied to rods of all sorts. The discovery of how to cleanly break them in two could be applied to future engineering projects.</p><p>Likewise, knowing how things fragment and fail is always handy to know when you're trying to build things. Carbon Nanotubes, <a href="https://bigthink.com/ideafeed/carbon-nanotube-space-elevator" target="_self">super strong cylinders often hailed as the building material of the future</a>, are also rods which can be better understood thanks to this odd experiment.</p><p>Sometimes big discoveries can be inspired by silly questions. If it hadn't been for Richard Feynman bending noodles seventy years ago, we wouldn't know what we know now about how energy is dispersed through rods and how to control their fracturing. While not all silly questions will lead to such a significant discovery, they can all help us learn.</p>
Reaching beyond the stereotypes of meditation and embracing the science of mindfulness.
- There are a lot of misconceptions when it comes to what mindfulness is and what meditation can do for those who practice it. In this video, professors, neuroscientists, psychologists, composers, authors, and a former Buddhist monk share their experiences, explain the science behind meditation, and discuss the benefits of learning to be in the moment.
- "Mindfulness allows us to shift our relationship to our experience," explains psychologist Daniel Goleman. The science shows that long-term meditators have higher levels of gamma waves in their brains even when they are not meditating. The effect of this altered response is yet unknown, though it shows that there are lasting cognitive effects.
- "I think we're looking at meditation as the next big public health revolution," says ABC News anchor Dan Harris. "Meditation is going to join the pantheon of no-brainers like exercise, brushing your teeth and taking the meds that your doctor prescribes to you." Closing out the video is a guided meditation experience led by author Damien Echols that can be practiced anywhere and repeated as many times as you'd like.
A study looks at the performance benefits delivered by asthma drugs when they're taken by athletes who don't have asthma.
- One on hand, the most common health condition among Olympic athletes is asthma. On the other, asthmatic athletes regularly outperform their non-asthmatic counterparts.
- A new study assesses the performance-enhancement effects of asthma medication for non-asthmatics.
- The analysis looks at the effects of both allowed and banned asthma medications.

Image source: joel bubble ben/Shutterstock<p>When inhaled β-agonists first came out just before the 1972 Olympics, they were immediately banned altogether by the WADA as possible doping substances. Over the years, the WADA has reexamined their use and refined the organization's stance, evidence of the thorniness of finding an equitable position regarding their use. As of January 2020, only three β-agonists are allowed — salbutamol, formoterol, and salmeterol —and only in inhaled form. Oral consumption appears to have a greater effect on performance.</p>
The study<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzUzNzU0Ny9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1MTIzMDQyMX0.Gk4v-7PCA7NohvJjw12L15p7SumPCY0tLdsSlMrLlGs/img.jpg?width=980" id="d3141" class="rm-shortcode" data-rm-shortcode-id="ebe7b30a315aeffcb4fe739095cf0767" data-rm-shortcode-name="rebelmouse-image" alt="runner at starting position on track" />
Image source: MinDof/Shutterstock<p>Of primary interest to the authors of the study is confirming and measuring the performance improvement to be gained from β-agonists when they're ingested by athletes who don't have asthma.</p><p>The researchers performed a meta-analysis of 34 existing studies documenting 44 randomized trials reporting on 472 participants. The pool of individuals included was broad, encompassing both untrained and elite athletes. In addition, lab tests, as opposed to actual competitions, tracked performance. The authors of the study therefore recommend taking its conclusions with just a grain of salt.</p><p>The effects of both WADA-banned and approved β-agonists were assessed.</p>
Approved β-agonists and non-asthmatic athletes<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzUzNzU1MC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxMzkxODk0M30.3RssFwk_tWkHRkEl_tIee02rdq2tLuAePifnngqcIr8/img.jpg?width=980" id="39a99" class="rm-shortcode" data-rm-shortcode-id="b1fe4a580c6d4f8a0fd021d7d6570e2a" data-rm-shortcode-name="rebelmouse-image" alt="vaulter clearing pole" />
Image source: Andrey Yurlov/Shutterstock<p>What the meta-analysis showed is that the currently approved β-agonists didn't significantly improve athletic performance among those without asthma — what very slight benefit they <em>may</em> produce is just enough to prompt the study's authors to write that "it is still uncertain whether approved doses improve anaerobic performance." They note that the tiny effect did increase slightly over multiple weeks of β-agonist intake.</p>
Banned β-agonist and non-asthmatic athletes<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzUzNzU1Mi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYzNjI3ODU5Mn0.vyoxSE5EYjPGc2ZEbBN8d5F79nSEIiC6TUzTt0ycVqc/img.jpg?width=980" id="de095" class="rm-shortcode" data-rm-shortcode-id="02fdd42dfda8e3665a7b547bb88007ef" data-rm-shortcode-name="rebelmouse-image" alt="swimmer mid stroke" />
Image source: Nejron Photo/Shutterstock<p>The study found that for athletes without asthma, however, the use of currently banned β-agonists did indeed result in enhanced performance. The authors write, "Our meta-analysis shows that β2-agonists improve anaerobic performance by 5%, an improvement that would change the outcome of most athletic competitions."</p><p>That 5 percent is an average: 70-meter sprint performance was improved by 3 percent, while strength performance, MVC (maximal voluntary contraction), was improved by 6 percent.</p><p>The analysis also revealed that different results were produced by different methods of ingestion. The percentages cited above were seen when a β-agonist was ingested orally. The effect was less pronounced when the banned substances were inhaled.</p><p>Given the difference between the results for allowed and banned β-agonists, the study's conclusions suggest that the WADA has it about right, at least in terms of selection of allowable β-agonists, as well as the allowable dosage method.</p>
