35 Crazy Cats That Will Have You Die Laughing.


Cats Are Crazy
A cat’s eyesight is both better and worse than humans. It is better because cats can see in much dimmer light and they have a wider peripheral view. It’s worse because they don’t see color as well as humans do. Scientists believe grass appears red to cats.
Spanish-Jewish folklore recounts that Adam’s first wife, Lilith, became a black vampire cat, sucking the blood from sleeping babies. This may be the root of the superstition that a cat will smother a sleeping baby or suck out the child’s breath.
Perhaps the most famous comic cat is the Cheshire Cat in Lewis Carroll’s Alice in Wonderland. With the ability to disappear, this mysterious character embodies the magic and sorcery historically associated with cats.f
In the original Italian version of Cinderella, the benevolent fairy godmother figure was a cat.
Two Siamese cats discovered microphones hidden by Russian spies in Holland’s embassy in Moscow  In Holland’s embassy in Moscow, Russia, the staff noticed that the two Siamese cats kept meowing and clawing at the walls of the building. Their owners finally investigated, thinking they would find mice. Instead, they discovered microphones hidden by Russian spies. The cats heard the microphones when they turned on.
The little tufts of hair in a cat’s ear that help keep out dirt direct sounds into the ear, and insulate the ears are called “ear furnishings.”
The ability of a cat to find its way home is called “psi-traveling.” Experts think cats either use the angle of the sunlight to find their way or that cats have magnetized cells in their brains that act as compasses.
Isaac Newton invented the cat flap. Newton was experimenting in a pitch-black room. Spithead, one of his cats, kept opening the door and wrecking his experiment. The cat flap kept both Newton and Spithead happy.

1. When you jump into the air, you fall back to the ground. Because gravity.

Isaac Newton first described the force of gravity. But he couldn’t really explain how it worked.

2. Matter bends space, and that’s how gravity is transmitted.

It was Albert Einstein who worked this out, several centuries after Newton’s discovery.

3. A mathematician called Theodore Kaluza tried to explain another fundamental force – the interaction of electricity with magnetism – in the same way.

4. He imagined that the universe had four dimensions instead of three.

A 34-Step Guide To String Theory, As Explained By Cats
Five dimensions in total, if you include time.

5. Then he worked out what equations would describe this universe.

6. Three of them were the same as Newton’s gravity equations that describe our own universe.

7. And there was one more. The final equation appeared to describe electromagnetism perfectly.

A 34-Step Guide To String Theory, As Explained By Cats
Electricity + magnetism = electromagnetism.

8. Of course, the extra dimension these equations needed to work was nowhere to be seen.

9. Physicists Oskar Klein suggested that the extra dimension was so tiny and curled up that we couldn’t see it.

10. Kaluza and Klein showed that the effect of gravity in the tiny, curled-up dimension would appear to us as electromagnetism.

11. Sadly, there was a hitch. The details of the theory didn’t work out.

12. So it went away for a few years.

13. And scientists got on with working out what the universe is made of.

14. Right now we think particles like quarks (they’re the ones inside protons and neutrons) and electrons are the smallest things that make up the universe.

A 34-Step Guide To String Theory, As Explained By Cats

15. But string theory says there could be something smaller: vibrating strings of energy.

A 34-Step Guide To String Theory, As Explained By Cats

16. These strings vibrate in different patterns.

A 34-Step Guide To String Theory, As Explained By Cats

17. Each pattern creates a different particle, such as an electron or a photon.

A 34-Step Guide To String Theory, As Explained By Cats

18. String theory unites the tiniest scales of the universe with the biggest.

A 34-Step Guide To String Theory, As Explained By Cats
It doesn’t get any bigger than gravitational interactions between huge astronomical objects.

19. But maths says string theory doesn’t work in a three-dimensional universe.

A 34-Step Guide To String Theory, As Explained By Cats

20. It only works in a universe with 10 dimensions of space and time.

A 34-Step Guide To String Theory, As Explained By Cats

21. Which takes us back to the idea that there are small, curled-up dimensions we can’t see.

A 34-Step Guide To String Theory, As Explained By Cats

22. These dimensions fold in on themselves and intertwine.

A 34-Step Guide To String Theory, As Explained By Cats

23. The shape of the extra dimensions affects how the strings can vibrate.

24. Which affects what particles they are, and what the universe looks like.

A 34-Step Guide To String Theory, As Explained By Cats

25. If these strings exist they’re a millionth of a billionth of a billionth of a billionth of a centimetre long.

A 34-Step Guide To String Theory, As Explained By Cats

26. Which means we can’t see them with our current particle accelerators.

A 34-Step Guide To String Theory, As Explained By Cats

27. There are several different versions of string theory.

A 34-Step Guide To String Theory, As Explained By Cats

28. In some theories the strings exist in closed loops. In others, they are open.

29. Some string theories require the universe to obey something called supersymmetry.

A 34-Step Guide To String Theory, As Explained By Cats

30. Supersymmetry says each particle we’ve found so far has a partner particle.

A 34-Step Guide To String Theory, As Explained By Cats
The partners might be heavier, which could explain why we haven’t seen any yet.

31. Evidence for supersymmetry would be good evidence that some version of string theory might be right.

A 34-Step Guide To String Theory, As Explained By Cats

32. As would finding hidden, tiny, curled-up dimensions.

33. The imprint of extra dimensions might even be visible in radiation left over from the Big Bang.

A 34-Step Guide To String Theory, As Explained By Cats

34. But right now, physicists are divided about whether any this evidence will ever appear.

35. Anyone for a nap?
