Thought for the month

“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”

Margaret Thatcher, 1 October 1996.

Fractional derivatives have physical reality

Proof has finally been achieved for Boltzmann's 140-year-old gas equation which predicts the motion of gas molecules. Robert Strain and Philip Gressman at the University of Pennsylvania have shown that Boltzmann's equation will always produce the right answer for gases that are close to equilibrium, such as the air in a building close to room temperature. However, they still can't say whether the equation holds in more complex situations, such as a storm.
