On Mondays, Wednesdays, and Fridays we use the wave theory; on Tuesdays, Thursdays, and Saturdays we think in streams of flying energy quanta or corpuscles.

My job is to give people who work hard all week something to enjoy on Saturdays and Wednesdays.

 

Arsene Wenger

 

A great many things are dying very violently all the time. The best days for violent deaths are Tuesdays. They are the yellow-paint days. Saturdays are second best -- or worst. Saturdays are red-paint days. The Great Death Game is therefore a contest between red-paint days and yellow-paint days. So far yellow-paint days are winning by thirty-one corpses to twenty-nine. Whatever the colour, a violent death is always celebrated by a firework.

A lot of the old movie stars couldn't act their way out of a box of wet tissue paper, but they were successful because they had distinctive personalities. They were predictable brands of breakfast cereal: on Wednesdays we had Quaker Oats and Gary Cooper; on Fridays we had Wheaties and Clark Gable. They were off-the-shelf products you expected always to be the same, actors and actresses with likable personalities who played themselves more or less the same role the same way every time out.

The Natural History Museum is open to the public on Tuesdays and Fridays. Elephant, rhinoceros, hippopotamus; extraordinary animals! Rubens rendered them marvellously. I had a feeling of happiness as soon as I entered the place and the further I went the stronger it grew. I felt my whole being rise above commonplaces and trivialities and the petty worries of my daily life.

One thing leads to another, and soon you are searching for answers to basic questions.
Another time during lectures on Classical Logic, we were introduced to an “experimentum crucis”. It was illustrated by the deciding experiment of Fizeau on the speed of light in water as compared to its speed in air. Since wave theory predicts that speed in water is less, and corpuscular theory (with point particles) predicts it would be faster, this is supposed to have selected the wave theory is correct. But then how would one accommodate the photoelectric effect? Then it turns out that if the “corpuscle” of light had a finite size, corpuscular theory also predicts lower speed of light in water. But then one can ask how come photoelectric emission being prompt even in feeble light, how could the energy of a photon spread over ?(?/2)2 act as a whole and liberate a single photoelectron! This leads us to question the square of the amplitude being interpreted as the probability of the particle being formed in the immediate vicinity. How do probabilities enter quantum mechanics? Thus the questions (and the quest) go on.
