Newton’s Birthday

Today’s Issac Newton’s birthday, the man who discovered the simple equations that predict the forces of gravity.

This simple equation is at the heart of Universe Sandbox. It’s what makes it all work.

And while his beautiful equation doesn’t work when you get really small or really big, it’s “adequate over an enormous range of masses of objects from about 10⁻²³ to 10³⁰ kg.” source

It’s amazing how something so simple can explain so much.

Happy Birthday Issac.

For comparison: Earth’s mass about 6 × 10²⁴ and the Sun’s mass is about 2 ×10³⁰ .
