Short one today, but I found this video really interesting:
I love a bit of Numberphile and if you remotely enjoyed this one you should check out every other video on the channel.
Anyway what I found interesting is that you can feel this very principle when weight lifting. It’s harder to jump from 10kg to 15kg in an exercise than it is to jump from 100kg to 105kg. It’s something intrinsic we kind of just ‘know’ in the gym, but you can see the theory behind it here.
Another point to take away from this is that you never entirely know when information is going to apply to your field of interest. Maths and physics may not seem connected to sport and exercise on the surface, but the entire field of biomechanics is based on it, so keep your eyes open for inspiration everywhere.
