Sexy math

This is what we needed in high school: a cute lady that loves math to also make us love math. Hannah Fry explains the importance of algebra in explaining the phenomenon around us and why using letters like “X” gives us enough flexibility to encompass many answers to out questions. Using letters in algebra lets you plot through a graph or gain more insights on some vectors (speed or acceleration by time or distance for example).

In any case, math is great and Hannah surely crushes some hearts wherever she goes 😀
