Classical physics In contrast to classical physics, "modern physics" is a slightly looser term which may refer to just quantum physics or to 20th and 21st century physics in general. Modern physics includes quantum theory and relativity, when applicable. A physical system can be described by classical physics when it satisfies conditions such that the laws of classical physics are approximately valid. In practice, physical objects ranging from those larger than atoms and molecules, to objects in the macroscopic and astronomical realm, can be well-described (understood) with classical mechanics. Beginning at the atomic level and lower, the laws of classical physics break
What the Bleep Do We Know!? to measure the position and momentum of subatomic particles... this only applies to sub-atomic particles—a rock doesn't need you to bump into it to exist. It's there. The sub-atomic particles that make up the atoms that make up the rock are there too." Hobbs also discusses Hagelin's experiment with Transcendental Meditation and the Washington DC rate of violent crime, saying that "the number of murders actually went up". Hobbs further disputed the film's use of the ten percent of the brain myth. David Albert, a philosopher of physics who appears in the film, has accused the filmmakers of selectively editing
