... Therefore, the statement given makes sense, since we need heavier stars to make the chemical elements upon which our lives are based. In fact, only the most massive stars, greater than about 10 solar masses, will ever form the chemical elements of iron and those more massive than iron, up to and inc ...

... observations made in inertial frames are physically equivalent, even though observers may disagree on the names of these forces (electric or magnetic). Today, we will look at a force (Newtonian gravity) that does not have the property that different inertial frames agree on the physics. That will le ...
