Happy Pi Day, everyone! Today is March 14, or 3/14, which corresponds to the first three digits of the number pi: 3.14 (and here are the first million digits of pi, if you are curious). But anyway, this seems like a great opportunity to celebrate some of the little-known facts about this spectacular number!

1. Pi probably contains literally all of the information that has ever existed or will ever exist.

The digits of pi never repeat, and they never end as far as we can tell. In fact, pi has been calculated up to 12 trillion digits without a single instance of repetition or sign of ending. Because pi contains such a variety of information, if you used a code such as binary to translate the 10-digit number system into letters, you could probably find anything that has ever been written -- or ever will be written -- inside of pi.

The Library of Babel is a website that operates on that principle. It uses an organization system to categorize literally every combination of letters and numbers shorter than 3,200 characters; you can find any passage of that length or shorter that has ever been written within its massive archives.

2. Last year's Pi Day was the coolest Pi Day of the century.

Pi Day is considered awesome because it matches the first two digits of pi. So, mathematically speaking, 53 seconds into 9:26 a.m. or p.m. on last year's pi day was exponentially more awesome by a factor of seven!

OK, that math may not exactly add up to a literal exponential factor of seven, but I was really happy to have celebrated the once-in-a-lifetime event of the "Ultimate Pi Day" last year. I took a screenshot of my computer's clock and everything!

3. Albert Einstein was born on Pi Day.

Albert Einstein is widely known as the extremely intelligent man who revolutionized the field of physics. You also may know him as one of the most widely misquoted people in history -- because, if you want to sound smart, why not pretend that the archetypal genius agrees with you?

Regardless, he was born on March 14, 1879. Maybe that is why he grew up to become such a mathematical genius!

4. Pi could prove that we are not living in a computer simulation.

Some philosophers have proposed the idea that everything we experience is just a computer simulation. They argue that everything we see is just virtual reality and, because of that, we cannot even tell if the universe is truly real. However, some have proposed that the existence of irrational numbers such as pi disproves the simulation hypothesis. Basically, as far as we know, computers cannot store an infinite amount of information. And, again as far as we know, tell pi contains an infinite amount of information. Therefore, pi seems to imply that reality is physically real and not just a computer simulation. Hooray!

5. Some people want to replace pi with tau, but they are wrong.

There is a very passionate movement online to replace the beautiful and sacred number pi that we have all come to know and love with a new, strange number called tau. Put simply, τ= 2 π. The nefarious proponents of tau claim that using it instead of piwould simplify most mathematical formulas. They argue it would make math easier to learn. They lay out these arguments in their holy text, "The Tau Manifesto," claiming that "the combination 2π occurs with astonishing frequency throughout mathematics" so we should use tau instead to make things simpler.

Not only is this heretical and gross, but it is also dead wrong. In a very detailed and in-depth analysis, Giorgia Fortuna at Wolfram found that only 18% of significant formulas involving π use 2π, which makes the Tau Manifesto's statement that the formulas they use as examples "are not cherry-picked" laughably wrong. If you want more details about why pi is superior to tau, I strongly encourage you to read that analysis as it goes into a lot of detail. Even if you don't read it, though, you can rest assured that pi is one of the coolest numbers out there!

Course registration at college can be a big hassle and is almost never talked about. Classes you want to take fill up before you get a chance to register. You might change your mind about a class you want to take and must struggle to find another class to fit in the same time period. You also have to make sure no classes clash by time. Like I said, it's a big hassle.

This semester, I was waitlisted for two classes. Most people in this situation, especially first years, freak out because they don't know what to do. Here is what you should do when this happens.

Whether you met your new love interest online, through mutual friends, or another way entirely, you'll definitely want to know what you're getting into. I mean, really, what's the point in entering a relationship with someone if you don't know whether or not you're compatible on a very basic level?

Consider these 21 questions to ask in the talking stage when getting to know that new guy or girl you just started talking to:

Challah vs. Easter Bread: A Delicious Dilemma

Is there really such a difference in Challah bread or Easter Bread?

Ever since I could remember, it was a treat to receive Easter Bread made by my grandmother. We would only have it once a year and the wait was excruciating. Now that my grandmother has gotten older, she has stopped baking a lot of her recipes that require a lot of hand usage--her traditional Italian baking means no machines. So for the past few years, I have missed enjoying my Easter Bread.

Top 10 Reasons My School Rocks!

Why I Chose a Small School Over a Big University.

I was asked so many times why I wanted to go to a small school when a big university is so much better. Don't get me wrong, I'm sure a big university is great but I absolutely love going to a small school. I know that I miss out on big sporting events and having people actually know where it is. I can't even count how many times I've been asked where it is and I know they won't know so I just say "somewhere in the middle of Wisconsin." But, I get to know most people at my school and I know my professors very well. Not to mention, being able to walk to the other side of campus in 5 minutes at a casual walking pace. I am so happy I made the decision to go to school where I did. I love my school and these are just a few reasons why.
