In a vacuum all photons travel at the same speed. They slow down when travelling through air or water or glass. Photons of different energies are slowed down at different rates. If Tolstoy had known this, would he have recognised the terrible untruth at the beginning of Anna Karenina? 'All happy families are alike; every unhappy family is unhappy in its own particular way.' In fact it's the other way around. Happiness is a specific. Misery is a generalisation. People usually know exactly why they are happy. They very rarely know why they are miserable.
I walked out to brood on this life of ours, which seems from birth to death to be a steady loss, disguised by sudden gains and happiness, which persuade us of good fortune, when all the while the glass is emptying.
I used to think marriage was a plate-glass window just begging for a brick.
Love demands expression. It will not stay still, stay silent, be good, be modest, be seen and not heard, no. It will break out in tongues of praise, the high note that smashes the glass and spills the liquid.
