Maths and physics you can see.

GradeSense turns ideas in maths and physics into pictures you can explore, one idea at a time.

The first few pictures

Maths and physics you can see, with a wave and a single marked point — Where we start.

A five by five square built from layers of one, three, five, seven and nine squares — Odd numbers add up to squares.

Newton’s cannonball: slow shots land, a fast enough shot circles the Earth — An orbit is falling and missing the ground.

What we’re building

Interactive explainers where you change the numbers and watch the picture respond, so an idea becomes something you can play with before you have to memorise it.

New pictures go up on Instagram first. Follow @gradesense
