Okay, so that last post was kind of intense, so I want to lighten the mood. Earlier today, I was thinking of what I could write for my next blog post. Unfortunately, I ran out of ideas, and I was bored. Being the weird math nerd that I am, I looked up “weird math facts” for fun. I saw some pretty wacky stuff, and I want to share it with you. Test out your knowledge of math – let’s see how many of these facts you’re familiar with.

So, did you know…

#### 1. If you write out pi backwards to two decimal places, it spells out “pie.”

#### 2. If you multiply 111,111,111 by 111,111,111, you get 12,345,678,987,654,321. Multiplying ones always results in palindromic numbers.

#### 3. If you shuffle a deck of cards properly, it is likely that the specific order of the cards has never been seen before in the history of the universe.

#### 4. There is not enough space in the known universe to write a googolplex on paper. (To clarify, googolplex is 10 to the power of a googol. A googol is 10 to the power of 10 to the power of 100. Another fun fact: Google was named after googol.)

#### 5. Calculus means “pebbles” in Latin because Romans used to use small pebbles to count on an abacus.

#### 6. Ancient Babylonians did math in Base 60 instead of Base 10 (the decimal system), which is why there are 60 minutes in an hour and 360 degrees in a circle.

#### 7. Newton discovered/invented calculus in the same amount of time that it takes a student to learn it.

#### 8. The number 7 is the most popular number, according to numerous studies. This is because it is “arithmetically unique.”

#### 9. A study found that students who chew gum have better test scores than those who don’t.

#### 10. Ted Kaczynski, more commonly known as the Unabomber, was a great mathematician – until he went insane and started killing people.

#### 11. A sphere has two sides – the outside and the inside.

#### 12. The man who discovered the Fibonacci Sequence used a pseudonym- his real name was Leonardo de Pisa.

#### 13. The only number that could not be written in Roman Numerals is 0. The Hindus were the first to discover this number.

#### 14. The “equal to” sign (=) was invented in 1557 by a Welsh mathematician, Robert Recorde, who didn’t want to write “is equal to” over and over in his mathematical papers.

#### 15. The Mona Lisa was painted according to the Golden Ratio (1.618). This number is found everywhere, not just in art.

#### 16. Circles aren’t the only shapes that have a constant width. Meaning, if I wanted, I could dig a square hole.

#### 17. 0.99999….. (repeating) = 1. There are proofs for this online, but I won’t get into that.

#### 18. In 1900, everything known about math could be written in about 80 books. Today it can fill more than 100,000 thousand books.

#### 19. The next sentence is true but you mustn’t believe it.

#### 20. The last sentence was false.

Alright, technically those last two weren’t actually facts. I just wanted to mess with you guys (I know, I know, I have an odd sense of humor).

Well, this was an extremely short post. I’ll end it by saying that I hope you guys learned something cool. Oh, and I’ll add a math-related picture, too.

Haha. Anyway, see you guys later!
