Today, we at Quelab are celebrating pi and it’s most epic of confluences 3.14.15! Pi, being the ratio of the circumference of a circle to it’s diameter, is an irrational number (which repeats infinitely without any repetitions) but is best approximated to the value 3.1415926. Since it is a geometric and mathematical constant, it’s something that we use unconsciously in our daily lives. the discipline undertaken by those who are obsessed with memorizing the digits of Pi is known as Piphilology, and is a skill which rarely comes in handy, but you never know when knowing pi to the 707th digit could win you praise and plaudits.
However, it is also a day to celebrate the Raspberry Pi, a gateway to learning about computers and programming from the ground up.
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.
For the numerical in the audience, here is a playlist of YouYube videos about Pi from some incredibly geeky folks from the channel “Numberphile”. There are even some tidbits in there for the Tau-fanatics.
What is this Tau you speak of? Double-Pi! Let Vi explain:
