20649 | The interference of light through two slits confirmed that it is waves [Watson] |
Full Idea: Thomas Young in 1803 confirmed the idea of Huyghens that light is waves, showing how light passing through two slits produces an interference pattern that resembles water waves sluicing through two slits. | |
From: Peter Watson (Convergence [2016], 04 'Conception') | |
A reaction: The great puzzle emerges when it also turns out to be quantised particles. |
20661 | Electrons rotate in hyrogen atoms 10^13 times per second [Watson] |
Full Idea: In the hydrogen atom the electron rotates some 10,000 billion times per second. | |
From: Peter Watson (Convergence [2016], 18 'Evolutionary') | |
A reaction: That's an awful lot. Is it at the speed of light? |
20647 | Quantum theory explains why nature is made up of units, such as elements [Watson] |
Full Idea: Planck's quantum idea explained so much, including the observation that the chemical world is made up of discrete units - the elements. Discrete elements implied fundamental units of matter that were themselves discrete (as Dalton had said). | |
From: Peter Watson (Convergence [2016], 4 'Intro') | |
A reaction: The atomic theory was only finally confirmed by Einstein in 1905. This idea implies that the very lowest level of all must have distinct building blocks, but so far we have got down to 'fields', which seem to be a sort of 'foam'. |
20654 | Only four particles are needed for matter: up and down quark, electron, electron-neutrino [Watson] |
Full Idea: We need twelve particles in the master equation of the standard model, but it is necessary to have only four to build a universe (up and down quarks, the electron and the electron neutrino (or lepton). The existence of the others is 'a bit of a mystery'. | |
From: Peter Watson (Convergence [2016], 11 'First Three') |
