The sleek geeks podcast

If your listening to music every morning on the the way to school or work then this may change your mind. If your wondering what I'm talking about it is the sleek geeks podcast. This is a podcast where Dr. Karl and Adam Spencer ask questions about maths and physics and then answer them. They have some fascinating topics including, why one is not a prime number (see my latest post for more details), the number 12, and all about the soccer world cup including advanced mathematical formulars, how the ball works, the history of the game and curving the ball like David Beckham. They are also a bit crazy and here is one of Adam's quotes from his Ted Talk (my second blog post) "In a room full of average people I'm a maths genius, but in a room full of phd mathematicians I'm as dumb as a box of hammers". He's very funny and super smart. You can download it on the podcasts app on your I-phone. the pod cast is called "sleek geeks".

Why 1 is not a prime number

This post investigates the mysterious question, why 1 is not a prime number. Let's quickly define what a prime number is (I have talked about primes before in an my older post called "Prime Numbers", which will tell you all about what a prime number is, and a cool video of Adam Spencer talking about "monster primes"). Alot of people think that number 1 is a prime number because the basic prime number rule is that the number can only be divided by itself and 1 (there are no other possible factors).  In this case, 1 divided by itself = 1, but that is actually the exact reason it is not prime.   In fact, even my sister's maths teacher was telling her class recently that 1 should be considered prime. So why is 1 not prime?  Because, as explained by my favourite mathematician Adam Spencer on the 26 June 2014  Sleek Geeks podcast The Number One, Big Data and Twittertime (you can find it on iTunes - just search up "Sleek Geeks" in Podcasts) no ...
