12 Interesting Math Facts

People Child School Genius Blackboard StudI love math and I love the way it makes way more sense than the English Language.  I also love certain facts I've learned about math that I want to share with you.

1. The Hairy Ball Theorem which boils down to "You can't comb all the hairs on a tennis ball without getting a cowlick."

2.  If you divide any number by 7 that does not have the result in integer form, you will see the numbers 142857 repeat in some way in the answer.

3. International paper sized A4 has a ratio of 1:square root 2.  If you cut the paper in half, the ratio remains constant and doesn't change.

4. There are 52 cards in a deck and 52! ways to shuffle the same deck giving you 80658175170943878571660636856403766975289505440883277824000000000000 different ways.  Such a large number and hard to conceptualize.

5. If you count in binary, you can count to 31 using one hand while if you use two hands you can count to 1023.

6.  73 is an interesting number because its the 21st prime number while its reverse 37 is the 12th prime number.  In addition, 21 = 7 * 3 and 73 when written in binary forms a palindrome of 1001001.

7. Although there are 3 dimensional objects such as Gabrielle's horn with an infinite surface area, they have limited volume.

8. There is a paradox which states you can cut a sphere up and reassemble it into two identical spheres which are exactly the same as the first.

9. If you randomly select 23 people and put them in the room, there is about a 50% chance 2 people in the room will have the same birthday.

10. If it were possible to fold a piece of paper 103 times, its thickness would be larger than the universe we can see.

11. The universe is not big enough to contain the written digits in a googolplex, even if each digit is the size of an atom. 

12. Since the ancient Babylonians did their math in base 60, they gave us 60 seconds in a minute, 360 degrees in a circle, etc.

I hope you found these facts as interesting as I did.  Let me know what you think, I'd love to hear.  Have a great day.
