Did you know the longest math equation ever solved is the Boolean Pythagorean Triples problem.

It would take 10 billion years for a human being to read it. With its phenomenal size of 200 terabytes—the equivalent of all of the digital texts held by the Library of Congress—it is the longest mathematical proof ever produced.

Whoa 😮😮 I can understand. when I download a pdf with 100 pages, it's hardly in single Digit MBs and 200TB!! I don't know maths too much but the simplest problems seemed to me the biggest ..

Cows Have Best Friends

An experiment was conducted placing together cows who’d known one another—AKA, their best friend—and those who were strangers. When placed with their best friends, the cow’s heart rates were significantly lower, as were cortisol levels (lower cortisol indicates lower stress). Both of these indicators shot up when cow friends were separated.

Sadly this research was conducted with an eye towards improving milk yields on farms. Not measured were stress levels when newborn calves are separated from their mothers.

It's undeniably funny. It's proof positive that animals have feelings, some more than others. There are some cowboys near my place and I've heard this story before.

Every business news outlet wants to be the one to unmask Satoshi Nakamoto.

It doesn't matter who Satoshi Nakamoto is. What matters is, he invented Bitcoin, by introducing the Bitcoin Whitepaper and we have freedom.

The unique smell of rain actually comes from plant oils, bacteria, and ozone.

These airborne oils combine with other compounds to produce the smell. In moist, forested areas in particular, a common substance is geosmin, a chemical produced by a soil-dwelling bacteria known as actinomycetes. The bacteria secrete the compound when they produce spores, then the force of rain landing on the ground sends these spores up into the air, and the moist air conveys the chemical into our noses.

Back in 1964, a pair of Australian scientists (Isabel Joy Bear and R. G. Thomas) began the scientific study of rain’s aroma in earnest with an article in Nature titled “Nature of Agrillaceous Odor.” In it, they coined the term petrichor to help explain the phenomenon, combining a pair of Greek roots: petra (stone) and ichor (the blood of gods in ancient myth).

In that study and subsequent research, they determined that one of the main causes of this distinctive smell is a blend of oils secreted by some plants during arid periods. When a rainstorm comes after a drought, compounds from the oils—which accumulate over time in dry rocks and soil—are mixed and released into the air. The duo also observed that the oils inhibit seed germination, and speculated that plants produce them to limit competition for scarce water supplies during dry times.

TIL The Statue of Liberty was once used as a lighthouse. After its dedication in 1886, it functioned as a working lighthouse for 16 years, with its torch visible from up to 24 miles away.

Yasushi Takahashi dumped his girlfriend and quit his job to go on a 6-month road trip across Japan, with the goal of creating a grand marriage proposal. Equipped with a GPS, Yasushi traveled 7,163 km (4,450 mi) mostly on foot, but occasionally using a car, ferry, and bicycle. When he returned home, he transferred the data to Google Maps, revealing the result as the words "marry me." This has earned him a certification from Guinness World Records as the largest GPS drawing worldwide.

Some people can voluntarily control their eye focus, making their vision blurry or unfocused.

The ability to defocus your eyes on command is a natural one, but not everyone can do it. It's accomplished by having the ability to relax the ciliary muscles in your eyes, which causes them to lose their focusing powers https://www.healthline.com/health/eye-health/can-everyone-unfocus-their-eyes

Turkey's first car. In the photo, the president of the time gets into the car to take it for a test drive. But unfortunately, it was forgotten to put gasoline in the car. They can't even go 1 meter. Because of this disappointment in front of the press, Turkey is giving up on producing its own car.

The remarkable anatomy of the octopus: Three hearts and nine brains

The octopus is an extraordinary marine creature, not only because of its three hearts but also due to the presence of nine brains. These unique adaptations are crucial to its survival and efficiency in complex underwater environments.

Three hearts

The three hearts function in a specialized manner: two of them, known as branchial hearts, pump blood to the gills, facilitating oxygen exchange, while the systemic heart circulates oxygenated blood throughout the body. Interestingly, the systemic heart stops beating during swimming, which explains why octopuses prefer crawling—they conserve energy by avoiding prolonged swimming, as it limits oxygen circulation.

Nine brains

Even more remarkable is the octopus’s neural system. In addition to a central brain, located between its eyes, each of the octopus's eight arms has its own mini-brain, or neural cluster, dedicated to controlling arm movement. This brings the total to nine brains. These decentralized brains allow the arms to function semi-independently, enabling the octopus to multitask efficiently. For example, an arm can explore, manipulate objects, or hunt prey without direct input from the central brain.

Blue blood

Moreover, the octopus’s blood is blue, due to the presence of hemocyanin, a copper-based molecule that excels at transporting oxygen in cold, low-oxygen environments. This, combined with the circulatory and neural systems, makes the octopus exceptionally well-adapted to life in the deep sea.

TLDR

The octopus’s complex anatomy—three hearts, nine brains, and hemocyanin based blue blood—demonstrates a remarkable example of evolutionary specialization, allowing these animals to thrive in a wide range of challenging marine habitats.

The GENDER of Satoshi Nakamoto is unknown.

While many people assume Satoshi is a man, there's no concrete evidence to support this. ▬▬ι══════════════ι▬▬

The pseudonym could belong to a single person, a group of people, or even a woman. ▬▬ι══════════════ι▬▬

The mystery surrounding Satoshi's identity adds to the allure of Bitcoin's creation.

Coffee was once banned

Coffee wasn’t always as loved as it is today. In the 18th century, governments tried to ban the beverage because it was thought to stimulate radical thinking. Our favourite drink was actually banned in Sweden for a while in 1746, along with anything related to it – including cups and saucers!

The first person convicted of speeding was going eight mph.

According to Guinness World Records, the first person to be charged with speeding Walter Arnold of the English village of Paddock Wood, Kent. On Jan. 28, 1896, Arnold was spotted going four times the speed limit in his 19th-century Benz—but since the speed limit at the time was just two miles per hour, that meant he was not going too fast by today’s standards.
