Happy Pi Day and Albert Einstein's 133rd Birthday!

In honor of both Pi Day and Albert Einstein's 133rd Birthday, here are some fun facts!

Pi Facts:

• Pi is the most recognized mathematical constant in the world. Scholars often consider Pi the most important and intriguing number in all of mathematics.

• Pi occurs in hundreds of equations in many sciences including those describing the DNA double helix, a rainbow, ripples spreading from where a raindrop fell into water, superstrings, general relativity, normal distribution, distribution of primes, geometry problems, waves, navigation....
  
• In 1706, an English mathematician introduced the Greek alphabet pi (π) to represent the said value. However, in 1737, Euler officially adopted this symbol to represent the value.

Here is a video with some more facts about Pi!

Now for some fun facts about Albert Einstein!

• Einstein Failed his University Entrance Exam
• In 1895, at the age of 17, Albert Einstein applied for early admission into the Swiss Federal Polytechnical School (Eidgenössische Technische Hochschule or ETH). He passed the math and science sections of the entrance exam, but failed the rest (history, languages, geography, etc.)! Einstein had to go to a trade school before he retook the exam and was finally admitted to ETH a year later.
  

• When Einstein was five years old his father gave him a pocket compass. It was this compass that sparked Einstein’s interest in science. The fact that the compass pointed in the same direction no matter how it was turned made him curious about understanding the force behind it.
   
• Einstein was offered the Presidency of Israel in 1952 but declined it.
  
• After Albert Einstein’s death in 1955 his brain was removed without approval from his family and an autopsy was conducted. Thomas Harvey conducted this autopsy and eventually it was discovered that Einstein’s brain had large portion of glial cells in the region that synthesizes information. Other studies also indicated that Einstein’s brain did not have a particular kind of wrinkle and this allowed the neurons to communicate better with each other.
