Newton’s first law of motion

“A body at rest will remain at rest, and a body in motion will remain in motion unless acted upon by an external force.”1

I proved this coming home on transit yesterday. I was sitting in a frontward facing seat (the first row of such seating) when the bus which travelling at top road speed suddenly halted to a stop (The bus driver slammed on the brakes to avoid a car which had suddenly come to a stop). I flew forward off the seat hitting the row of seats in front and landing on the floor of the bus. Luckily, I wasn’t hurt, but everyone tried to make a big deal of it. I, in my usual manner, got up and dusted myself off.

So, physics is alive and well (and some people like to assert that they don’t use math and science in everyday life. It’s there; we just don’t think about it).

It’s not often this science major gets to write science-y stuff for my blog.
