Thought for the month

“You always own the option of having no opinion. There is never any need to get worked up or to trouble your soul about things you can't control. These things are not asking to be judged by you. Leave them alone.”
Marcus Aurelius Antonius, Emperor and Stoic philosopher (121-180).

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.
