Day 99

Bit by bit, Sean seems to recover from a 2nd defeat and comes back at table tennis games. He was so nervous during the game yesterday that he lost to me. He broke down before finishing the game that he had been longing to for almost a week. He called it the "big game". And he crashed the match ball on purpose.

Today he lost again, but I encourage him to come back. I asked him not to think about the errors he had made, but to think about how he succeeded in beating me in the past and to think about what he did best. I reminded him that the reason he lost is not because I become stronger but he becomes weaker instead. He needs to bring the best out of him.

Apart from table tennis, we enjoyed watching science documentaries by Jim Al-Khalili. Everything and nothing: indeed something can be created out of nothing due to quantum fluctuation. Vacum doesnot mean nothing. Energy transforms to matter and anti-matter, and vice-visa.

The 1st law of thermal dynamics: the total amount energy in the world is constant. Heat always transfers from hot objects to cold objects. It is a one way process. The 2nd law of thermal dynamics: the entropy is always increasing for an isolated system. The elapse of time is also a one way process.
