Well, science and baseball. Physicists build models to explain how the world works. It might be an equation, like the ideal ...

Physicists have just dropped a new precise measurement for gravity. The newly published value for the strength of gravity, known as “G” or “Big G”, is significantly smaller than some previous ...

For more than 200 years, scientists have struggled to pin down the exact strength of gravity — and one physicist spent a decade chasing the answer while keeping his own results hidden from himself.
