Sir Andre Geim, who had been awarded an Ig Nobel Prize (a satiric prize) in 2000 for levitating a frog by magnetism, was awarded a Nobel Prize in physics in 2010 for his work with the electromagnetic properties of graphene. He is the only individual, as of 2023, to have received both a Nobel and an Ig Nobel. https://en.m.wikipedia.org/wiki/Ig_Nobel_Prize

Anti-Tank Dogs - противотанковые собаки

The Anti-Tank Dogs were a Soviet military program where German Shepherds were trained to carry explosives to tanks and armoured vehicles. 40,000 dogs were intended to assist in curbing the German advance at the eastern front.
The first issues arose when the dogs wouldn't dive under the active enemy tanks as they'd only been trained on non-moving and non-shooting vehicles, so they would become scared return to their handlers... which could lead to explosive consequences!
Another serious issue was that the Soviets trained the dogs using their own diesel engine-powered tanks, however the German tanks used gasoline engines. Given dogs rely heavily on their keen sense of smell, they immediately sought out the familiar Soviet tanks, completely ignoring the strange-smelling German ones. As you can imagine, this wasn't particularly ideal for the longevity of the Soviet crews.
The program was started in 1930 and lasted until 1946 when, plagued by issues, it was unsurprisingly shut down.

I learnt a lot writing this fun fact, and not just in writing the post but in preparing a good image. All original photographs from the time period are very low quality (100x100px) and in black & white. To bring the photo up to a standard suitable for Stacker News, I used three tools to help augment the photo:
  1. upscaling using Clipdrop
  2. colourisation using img2go
  3. touch-ups/tweaks using GIMP

German chocolate cake was invented in Texas
The “German” part of German chocolate cake comes from an American man—not a European country. Specifically, it’s named after Sam German, who in 1852 created the formula for a mild dark baking chocolate bar for Baker’s Chocolate Company, which was subsequently named Baker’s German’s Sweet Chocolate. Fast-forward to June 13, 1957. The Dallas Morning Star published the recipe for the cake, invented and submitted by a reader identified as Mrs. George Clay, according to What’s Cooking America.

Lightning can do sub-satoshi payments: payments can be made conditional upon the outcome of a random event, allowing probabilistic payments. For example, Alice can pay Bob 0.1 satoshi by creating a 1-satoshi payment with 10-to-1 odds so that 90% of the time she does this she pays him 0 satoshis and 10% of the time she pays him 1 satoshi for an average payment of 0.1 satoshis.

By this logic a man and a woman (assuming they are both fertile and not using any contraception) make some fraction of a baby every time they have sex
reply
And when they get divorced they can "split the children" for custody!
But no, because it is like if you were likely to impregnate once every ten times having sex. One of those ten times you make 100 percent of a baby.

Since 1977, the American flag was officially modified 26 times

The first flag had 13 stripes and 13 stars arranged in a circle. Both the stars and the stripes represented 13 colonies that declared independence from the Great Britain. Each new flag was the addition of new states. The 48-star flag stood for 47 years until the 49th version of the flag became official on 4th July 1959. Today it displays 50 stars that represent the 50 states of the United States of America.

These Alaskan frogs freeze almost completely at the start of winter, with two-thirds of their body water turning into ice. To all intents and purposes, they seem dead; their heart stops beating, and their blood flow stops. However, once winter starts to thaw so do they and they hop back to life.

Fact: There’s enough gold inside Earth to coat the planet Turns out, there’s quite a bit of gold on—or, really, in—our planet: 99 percent of the precious metal can be found in the Earth’s core, Discover Magazine reports. How much is there? Enough to coat the entire surface of the Earth in 1.5 feet of gold.

Did you know that Satoshi already responded to the U.S. Department of Energy's concerns about Bitcoin's electricity use... in 2010?
In response to a post by gridecon, which reads in part: "I believe that the amount of energy input required to the bitcoin economy represents a serious obstacle to its growth."
Satoshi ⚡️ responded:
It’s the same situation as gold and gold mining. The marginal cost of gold mining tends to stay near the price of gold. Gold mining is a waste, but that waste is far less than the utility of having gold available as a medium of exchange. I think the case will be the same for Bitcoin. The utility of the exchanges made possible by Bitcoin will far exceed the cost of electricity used. Therefore, not having Bitcoin would be the net waste.
In other words, Satoshi said that Bitcoin is so useful to the economy that it would be more wasteful not to direct our electrical resources at it... 🧐

The Wizard of OZ Snow was Asbestos

The poppy field scene in "The Wizard of Oz" became infamous over the years after viewers learned that the fake snow in the scene was 100% asbestos. Chrysotile, which is white asbestos, was also used for this scene. Despite the fact that asbestos' health risks were already known at the time, film sets started using one of the purest forms of asbestos on film stages because it was fireproof and looked close enough to snow that it could fool the audience.
reply
The health risk of asbestos was common knowledge in 1939?

The members of the Butan tribe have a rare genetic defect that gives them electric blue eyes

The Butan tribe is in a remote part of Sulawesi in Indonesia. This is because of a rare genetic disorder called Waardenburg syndrome which causes congenital hearing loss and pigmentation deficiencies, which can include bright blue eyes. Your eye color results from the amount of melanin your body makes. Melanin is a pigment that gives color to your eyes, hair and skin. The colored part of your eye is called the iris. As many as 16 genes influence eye color by determining the amount of melanin inside the specialized cells of the iris. Different eye colors are caused by different amounts of pigment.
Maybe this is not such a fun fact for people affected, however I certainly learnt something this morning.

Buenos Aires Has the Widest and the Longest Street in the World The grand Avenida 9 de Julio is named after the country’s Day of Independence, celebrated on the 9th of July. This colossal avenue spans a staggering 459 ft in width and accommodates 16 lanes of traffic. The street is home to historic buildings, monuments, and landmarks like the Obelisco, making it worth exploring when you visit Argentina. While Av. Rivadavia has more than 35km of distance.
So, we Argentineans, have the widest and the longest! (if you know what I mean).

Hmmm wonder how they paid for that...

People often say if you were to represent pi with letters, every book ever written would be contained therein.
We do not know if this is true or not. In order for this to be true, a number has to be "normal", meaning each number has the same density as every other number. And not just single digit number, but two digit numbers, three digit numbers, and so on. In other words, 11 must have the same density as every other 2 digit number.
It has never been proven that pi is normal, and so we do not know if the initial statement is true. There are conjectures that it is true, but this has yet to be definitively proven. It could be that after some arbitrarily large number, 11 stops occurring with the same density as other 2 digit numbers.

Human beings can use only a small fraction of Earth’s water In school, we were taught that most (specifically, 71 percent) of the planet’s surface is covered in water. While that’s true, humans can use only 0.007 percent of that water, according to National Geographic. That’s because only about 2.5 percent of Earth’s water is fresh water, and only 1 percent of that is accessible. The rest makes up glaciers and snowfields. By the way, have you ever wondering why we can “smell” snow? https://www.rd.com/list/interesting-facts/

Carnvory is no longer a fad in the Bitcoin community.
There is a growing movement of vegans and vegetarians in the Bitcoin space. This is due in part to the environmental impact of meat production, as well as the ethical concerns surrounding animal welfare.
Bitcoiners like their stake, like their money; rare!
