The Importance of the EXPONENTIAL Function!

Ok. My mum stumbled upon this video while trying to kill time. Since its "The Most IMPORTANT Video You'll Ever See", I thought it would be worth sharing.

This 8 part series talks about the real life implications of the exponential function. May be a bit boring at first - not to worry.. Sit back and let the sheer power of the exponential sweep you away.



Ok fine.. I've only watched the first one (as of this post..).

Takeaways from this video:

1) Doubling time: 70 (aka ln2 x 100%) / percent growth per unit time (e.g. year)

2) Hence for something to double in 10 years, growth per year is around 7%.

3) If *something* increases at a constant % per unit time, by the next doubling time, total quantity of *something* would have more than doubled the sum of *something* before the previous doubling time.

Ok! Watch the video for yourself! (and you would probably have a better understanding compared to the random blabbering above)
