  • How Quickly Can a Bacterium Grow?
    All living things must obey the laws of physics — including the second law of thermodynamics, which states that the universe's disorder, or entropy, can only grow. Highly ordered cells and organisms appear to contradict this principle, but they actually do conform because ...More
