That's not correct for most cases. You need very specific conditions to reproduce the Mpemba effect.

/\ This counterintuitive fact has been commented on since ancient times, including Aristotle.

Various effects of heat on the freezing of water were described by ancient scientists, including Aristotle: "The fact that the water has previously been warmed contributes to its freezing quickly: for so it cools sooner. Hence many people, when they want to cool water quickly, begin by putting it in the sun." Aristotle's explanation involved antiperistasis: "...the supposed increase in the intensity of a quality as a result of being surrounded by its contrary quality.

There are more trees on Earth than stars in our galaxy/

NASA experts believe there could be anywhere from 100 billion to 400 billion stars in the Milky Way. However, a 2015 paper published in the journal Nature estimated that the number of trees around the world is much higher: 3.04 trillion.

The number 3 is one digit.
The number 3^3 has 2 digits.
The number 3^3^3 has 13 digits.
The number 3^3^3^3 has 3,638,334,640,025 digits.

Humans have genes from other species.

We like to think of humans as being superior to other living creatures, but the reality is that our genome consists of as many as 145 genes that have jumped from bacteria, fungi, other single-celled organisms and viruses.

The longest unbroken alliance in world history is between England and Portugal. It has lasted since 1386 and still stands today.

On 23 Mar 94, Aeroflot Flight 593 crashed because the pilot let his kids fly the plane who unknowingly disengaged the autopilot function. The crash killed everyone on board.


Although the kid caused the initial issue, there were subsequent pilot errors that made the plane crash

It can rain diamonds on other planets.

The atmospheres on Neptune, Uranus and Saturn have such extreme pressure that they can crystallize carbon atoms and turn them into diamonds.

There are over 6,000 known species of grass.

Carbon dioxide cannot become a liquid under standard atmospheric conditions (aka in everyday life). It directly sublimates from it gaseous form into a solid at -78°C / 195K.


To get liquid carbon dioxide a minimum pressure of 5.1bar is necessary (five times the average atmospheric pressure at sea level).

The logo on the Red Bull cans are not bulls, but a type of bovine called a “gaur.”


I guess Red Gaur was not catchy?

There were roughly 2.5 billion T. rexes on Earth, but not all at the same time.

Humans have been marveling at the size of the T. rex ever since they first put a full skeleton together. Now, thanks to research published in April 2021, scientists have a better idea of exactly how many of them once called Earth their (temporary) home. According to the team at the University of California, Berkeley, approximately 2.5 billion of these dinosaurs existed across more than 127,000 generations. They reached this estimate by figuring out what age T. rexes lived to, taking into account the dinosaur’s body size, sexual maturity and energy needs.

/\ Sue, the oldest T-rex found, made it to age 33; but the average lifespan was 22 years.

The collective group of lemurs is called a conspiracy.


Of course, that's what the Lemurs want you to believe :shifty:
