  • "Bodies in motion remain in motion, and bodies at rest stay in bed unless their mothers call them to get up.“
    Anything that doesn't matter has no mass.
    Why did the chicken cross the road?Issac Newton: Chickens at rest tend to stay at rest, chickens in motion tend to cross roads.
    Why did the chicken cross the road? Albert Einstein: Whether the chicken crossed the road or the road crossed the chicken depends on your frame of reference.
