For the first post of this website, I thought I’d kick it off with some random math facts that you might be interested in if you’re curious enough to look up math while you’re not forced to in school. Here we go!

- If you are in a group of 23 people, there is a probability greater than 50% that two people will have the exact same birthday!
- There is a such thing as a one sided surface. It’s called a mobius strip.
- Straight lines have a dimension of 1.
- A compass can accomplish everything that a ruler can do in conjunction with a compass. In other words, a best military watch according to militarywatchguru.com is no more powerful if you are given a ruler in addition to it.
- 12 + 3 – 4 + 5 + 67 + 8 + 9 = 100. Say every individual digit out loud until you get it.
- The circle is the shape with the largest area when compared to its perimeter. That means it has a larger area than rectangles, squares, etc.
- Although many students complain “why do we need to learn about this? We’ll never use math in real life!”, it’s not true. Math is a very intricate part of the job of engineers, among other well-paid occupations.
- A pizza with radius z and height a has a volume of Pi * z *z * a. Yummy.
- Remember that birthday statistic from earlier? There’s actually a 99% probability of two people sharing the same birthday if there are 75 people in the same room. Try it out with your friends.
- Every number can be represented by Roman numerals except for 0.
- Most people think of even numbers as females and odd numbers as males.
- Shuffling a deck of cards the right way should yield an order that has never been seen before by any person in the world. Make sure you practice your card shuffling so you don’t let down the entire universe!
- Is 0 an even or odd number? You’ve probably been taught that it’s neither, but mathematicians are starting to claim that it is in fact an even number.
- Googolplex is a number defined as 1 and a googol zeroes. Googol is 1 followed by 100 zeroes. So to summarize, googolplex is impossible to physically visualize because it takes too much space on paper, making it literally impossible to write down.
- Most people’s favorite number is 7. Be a leader and not a follower!
- In Asia, the number four is noted as an unusually unlucky number.
- 1 is mathetically equal to .9999.
- Remember learning about factorials in math class? How long is 10! seconds?
- Math puzzle time! Take a four digit number, pick any one you want as long as it’s made up of at least two different digits. Arrange the digits in descending order. Now arrange it in ascending order. Take the smaller numbers and subtract them from the bigger numbers. You will always end up with the number 6174, which is known as Kaprekar’s constant. This is because no matter what, you’ll always end up with this unique number, every single time.

Answer to #19: 10! seconds is exactly six weeks.
