Quantum Mechanics verything in the universe is made of Everything in the universe is made of tiny discrete particles. These particles behave sometimes like waves, and their positions and motions can only be described in terms of probabilities. Quantum mechanics has well defined procedures to calculate anything connected with an experiment ll its predictions have been shown to be correct All its predictions have been shown to be correct. It underlies all of our understanding of physics and chemistry. uantum mechanics together with our empirical Quantum mechanics, together with our empirical knowledge of chemistry, appears to provide us with a ‘foundation of certainty’ on which to build biology.” Francis Crick (1962 Nobel Laureate in Physiology or Medicine)

The Standard Model The Standard Model is the most precise physical theory er developed Millions of ever developed. Millions of experiments have been done to test it, and all are in agreement with it. These often include mathematical values precise to 15 or more decimal places. “Once you know about gauge particles Once you know about gauge particles [force carriers], quarks, and leptons, ou know everything there is to know. Sheldon Glashow you know everything there is to know. That’s all there is. There ain’t no more.”
