There are numerous examples of breakthroughs that humans have used or discovered in their
existence that have catapulted us to the top of the food chain.
The wheel, the steam engine, the printing press, etc.
These advances are known to most people, and we realize that without those things existing,
we’re still in the dark ages.
But there are also lots of little blips on the timeline throughout human history of simpler
things between the lines.
These technologies may not have the same lustre as the heavy hitters, but if you tried to
imagine your daily life without these things being developed and perfected, you would quickly
see that they’re every bit as important.
Here are some simple technologies that changed the world in profound ways.
10.
Duct Tape
That sticky grey tape that seems to hold most of the world together these days draws its
history back to the Second World War.
The military used the tape to keep their ammunition boxes sealed, but quickly found that there
were tons of other uses for it.
What began as medical tape was found to have incredibly adhesive qualities as well as inherent
waterproofing, which led to soldiers calling it “duck tape,” referring to a duck’s
wicking feathers.
Once the war ended, soldiers returned home and began buying houses en masse.
They also took lots of jobs with construction companies, and told their bosses about this
incredibly sticky tape they used during the war.
The tape was used for all sorts of HVAC applications, but mostly for holding ductwork together.
So “duck tape” became “duct tape,” but in 1998, a test of common HVAC sealing
materials was conducted.
Duct tape came in dead last.
Quack.

Teflon pans
When scientists in the 1930s developed a new kind of polymer that was superbly heat resistant
and uber-slippery.
They used it in war, because that’s just what was going on at the time.
But it took until the ‘60s when they decided that it would be great for keeping food from
sticking to pans.
And it wasn’t just pans–the non-stick coating known as Teflon changed the home kitchen
for good by also being applied to muffin and cake tins as well as cookie sheets.
Clean up was a breeze.
The coating could handle high heat.
The only thing they were kind of bad at was not killing people.
The workers that produced Teflon were basically poisoned by the material, and that sickness
was passed on to lord knows how many consumers.
One of the components in Teflon that was responsible wasn’t banned until 2014.

Smoke detectors
Think of all the things you probably take for granted in our homes in the present day,
and smoke detectors are likely near the top of the list.
Those little gadgets have saved countless lives, yet you hardly notice them until their
batteries run low.
They’ve become standard and required in homes these days, so it’s hard to imagine
a time when they weren’t around.
And they happened by accident.
In the 1930s, a scientist in Switzerland was trying to make a device that detected poison
gas in the air.
While it failed to pick up the presence of the tested poison, when he lit a cigarette,
the smoke did trip the alarm.
It took until the late 1960s before they found their way into homes, and have now cut fire-related
deaths by half.
7.
Viagra
A little blue pill that’s only been around for twenty years shouldn’t have such an
impact on the world that it’s had, especially since it’s not cured any major disease,
instead letting men experience the wonder of full erections.
But Viagra has basically changed sex around the world.
In 1991, testing began on what would become Viagra, but it was developed with the intention
of lowering blood pressure.
But during the studies, there was a certain side effect that the men involved could not
ignore.
The development of the drug headed in the direction of restoring sexual health to men,
and within ten years, 200,000 prescriptions a week were being filled.
It changed the way men confronted diminishing sex drives.
It also helped unknown diseases related to erectile dysfunction become treated when men
came to the doctor seeking Viagra.
6.
Credit cards
A fixture of every wallet known to man, the credit card is simultaneously boosting the
economy and bankrupting countless people with no financial acumen.
The concept of “pay us later, we’re sure you’re good for it,” and then tacking
on insane interest amounts is a fairly new concept.
At least in card form.
But they’re ubiquitous now, with around 18 billion in use.
In 1949, businessman Frank McNamarawas at a restaurant and realized he had forgotten
his wallet.
This made him envision a kind of card that could be used at multiple businesses.
He started Diners Club the next year, and within the next decade, more and more banks
started making their own credit cards.
Fast forward to present day, and Americans alone possess over a trillion dollars in credit
card debt.
So in less than a hundred years, we’ve done some damage, haven’t we?
5.
UPC Codes
You’ve seen that little box of black lines on the side of every product you buy, even
more so when you’re struggling to find them in the self-checkout line.
The UPC code gets scanned, the price shows up, and it’s a pretty expedient process.
But how did that get to become the norm?
In 1948, Joseph Woodland (who had actually worked on the Manhattan Project to develop
the first nuclear bomb) was responding to a query from a local store owner about how
to speed up the process of buying products in his store.
Woodland thought about Morse Code and its simple way of giving lots of information with
dots and lines, so he made that his inspiration.
His innovation could describe an item and its price all at once, instead of the snail’s
pace of non-automated operations that most stores suffered through.
The only thing that held back progress was the lack of computers readily available to
read the code, so it took until 1974 when the technology began to roll out to stores
nationwide.
4.
Barbed wire
Two problems faced the American West as it grew and expanded: cattle were getting loose
and trampling precious crops, and there wasn’t enough wood in those regions to build fences.
The Homestead Act of 1862 made it so many people could get vast tracts of land for next
to nothing, so it was important that they be able to work that land and have secure
properties.
Enter Joseph Glidden of Illinois, who patented barbed wire in 1874.
It wasn’t without its growing pains, as the wire trapped dumb cows by the thousands,
and cowboys hated their herds being restricted by the artificial borders.
And those very borders that marked a person’s property also screwed over Native Americans,
as these practices left them with even fewer claims to their ancestral lands.
The Homestead Act required that a person build a home and work the land for five years before
it would become theirs to own.
The barbed wire was a metaphorical and physical realization that their way of life was over.
3.
Velcro
Zippers were still very much the rage in 1941, when Swiss engineer George de Mestral came
upon an idea while walking his dog in the woods one day.
He noticed how his clothing and his dog were covered in sticky burrs, the pointy little
things that always prick your fingers are you’re removing them.
Under a microscope, he saw how the curved hooks of the burrs met with his clothing in
an almost perfect marriage.
Zippers were no longer the only game in town.
Zippers tended to jam all the time.
Velcro, as it would come to be in 1955 (from the French words “velour” and “crochet”)
didn’t have that problem.
Though originally implemented in clothing, it’s now used in everything from sporting
equipment to NASA craft.
And whoever began using it in little kids’ clothing should eventually get their own medal.
2.
Daylight saving time
Ok, so maybe not exactly a technology, but the advent of daylight saving (it’s not
“savings”, by the way) time has changed a lot about our modern world.
First started in Germany in 1916 as a way to enjoy the sunshine and to conserve electricity,
it began to catch on in other countries around the world soon after.
In the United States, it was started in 1918 as a wartime practice.
It was repealed the next year after farmers protested; the next few decades saw back and
forth fighting and different start times for daylight saving across the country.
Finally in 1966, the Uniform Time Act made time, uh, uniform across the country.
The central concept, energy conservation, doesn’t really seem to be a benefit though.
The stuff that uses the most electricity in our homes are things that get used the more
we are home, if that makes sense.
It seems that the money that gets boosted into the economy by people enjoying more leisure
“daytime” in the evening is enough to keep the practice in use.
1.
Transistors
Think of the devices that power your everyday life: smartphones, computers, tablets, etc.
They all have one thing in common at their very core, and that’s the very simple transistor.
The development of the transistor signaled the developmental shift from hardware to software,
and it’s why technology has surged light years ahead since its inception.
A transistor is merely a type of semiconductor that either amplifies signals or switches
them.
Invented in 1947, it was a device far ahead of its time, and as computing devices grew
and became more efficient, so too did the transistor.
Computers got smaller and became household items, while transistors shrunk down to the
size of a few nanometers.
Those tiny transistors are one of the only unchanged (aside from size) building blocks
of the entire digital age.
