Degrees vs Radians

For those of you lucky enough to be taking maths at as level, you'll have come across a lovely new way of measuring angles - Radians. It really makes you think why did we choose to be using degrees for so long if use of radians at 16 was inevitable. I mean 360 is a pretty random number.
Why 360? well we don't know. Some people think it's because ancient astronomers thought that there were 360 days in a year, yes, stupid. So why did we carry on with it? Why is it when we found out there were actually 365 days in a year we stopped using degrees? well 360 is actually a very useful number, lots of numbers go into it (oi oi), like 1,2,3,4,5, and 6, this also links to the use of counting with sexagesimal numbers (oi oi) which basically means counting in base 10. But that's a whole different story. In short, it makes 'sense' to use radians rather than degrees, but we find it harder because we've been using degrees for so long.
