2,420. The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition resting on sympathetic understanding of experience, can reach them. (Science & Physics & Cosmology & Logic & Intuition & Experience & Laws & Universe) Albert Einstein, cited Principles of Research 1918
71,436. Thus the device by which an organism maintains itself stationary at a fairly high level of orderliness (= fairly low level of entropy) really consists in continually sucking orderliness from its environment. (Entropy & Laws) Erwin Schrödinger, What is Life?
2,429. The law that entropy always increases, holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations – then so much the worse for Maxwell's equations. If it is found to be contradicted by observation – well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation. (Science & Entropy & Nature & Theory & Laws) Arthur Eddington, The Nature of the Physical World 1928
2,373. Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it. (Physics & Newton & Action & Motion & Science & Laws & Gravity) Isaac Newton, Principia Mathematica, Laws of Motion I
48,766. The alternation of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. (Physics & Newton & Action & Motion & Science & Laws & Gravity) ibid. Laws of Motion II
4,478. To every action there is always opposed an equal reaction; or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts. (Physics & Newton & Action & Motion & Science & Laws & Gravity) ibid. Laws of Motion III
2,540. Hooke had spurned the one man with the mathematical talents to help him understand the laws of the universe. (Science & Isaac Newton & Mathematics & Laws) Genius of Britain: The Scientists who Changed the World, Channel 4 2012, Jim Al-Khalili
2,543. The greatest book ever written in history ... Principia Mathematica. (Science & Isaac Newton & Mathematics & Laws) ibid.
2,544. The Principia spelled out for the first time the mathematical principles that governed the universe. And the law of gravity that holds all matter in place. (Science & Isaac Newton & Mathematics & Gravity & Laws) ibid.
48,728. How did humans acquire the power to transform the planet like this? Looking at the Earth at night reveals to us just how successful we’ve been in harnessing and manipulating energy, and how important it is to our existence. Energy is vital to us all. We use it to build the structures that surround and protect us. (Energy & Physics & Laws) Order and Disorder with Jim Al-Khalili I: Energy, BBC 2012
48,729. Energy is essential to life itself. (Energy & Physics & Laws) ibid.
48,730. What exactly is energy? And what makes it so useful to us? (Energy & Physics & Laws) ibid.
48,731. Scientists would come up with a strange set of laws that would link together everything from engines to humans to stars. (Energy & Physics & Laws) ibid.
48,732. Almost no-one had understood the fundamental nature of the steam engine; very few were aware of the cosmic principle that underpinned it. (Energy & Physics & Steam & Laws) ibid.
48,733. Left alone energy always seems to go from being concentrated to being dispersed. (Energy & Physics & Laws) ibid.
48,734. The second law of thermo-dynamics and it turned out to be stranger and more beautiful, more universal ... All things that gave off heat were in some way connected together. All things that gave off heat were part of an irreversible process that was happening everywhere. A process of spreading out and dispersing, a process of increasing entropy. It seemed that somehow the universe shared the same fate as a cup of tea. (Energy & Physics & Universe & Laws) ibid.
48,735. Entropy – why was it always increasing? (Energy & Physics & Laws) ibid.
48,736. Entropy was in fact a measure of the disorder of things. (Energy & Physics & Laws) ibid.
2,582. Boyle’s List: all but two of twenty four things on this list have now been achieved by science. (Science & Laws) Science Britannica III: Clear Blue Skies
2,583. George Watt and George Stevenson harnessed steam power. Where Rutherford and Chadwick unravalled the architecture of the atom. Where Edward Jenner worked out the principles of vaccination ... (Science & Steam & Atom & Vaccination & Laws) ibid.
2,595. The purpose of scientific enquiry is not to compile an inventory of factual information, nor to build up a totalitarian world picture of natural Laws in which every event that is not compulsory is forbidden. We should think of it rather as a logically articulated structure of justifiable beliefs about nature. (Science & Inquiry & Laws & Nature) Peter Medawar, Induction and Intuition in Scientific Thought 1969
2,685. Scientific principles and laws do not lie on the surface of nature. They are hidden, and must be wrested from nature by an active and elaborate technique of inquiry. (Science & Laws & Nature & Inquiry) John Dewey, Reconstruction in Philosophy
2,708. The same laws of physics apply everywhere throughout the cosmos. (Universe & Cosmology & Physics & Laws) Professor Carl Sagan & Ann Druyan, Cosmos: The Shores of the Cosmic Ocean, 1979
2,727. The extraordinary thing is not that there are laws but that we can understand them. Why should we be able to understand them? (Universe & Laws & Science & Cosmology & Understand & Anthropic Principle) Dr David Deutsch
2,728. It’s the comprehensibility of the Laws of Physics that makes the Anthropic Principle work. (Universe & Laws & Physics & Anthropic Principle) Dr David Deutsch
2,741. In effect, we have redefined the task of science to be the discovery of laws that will enable us to predict events up to the limits set by the uncertainty principle. (Universe & Laws) Stephen Hawking, A Brief History of Time 1988
96,076. The second law of thermodynamics: it states that the entropy of an isolated system always increases, and that when two systems are joined together, the entropy of the combined system is greater than the sum of the entropies of the individual systems. (Entropy & Laws) ibid. p112
2,757. Why is the universe the way it is? Why does it follow rules and laws? Why is there order instead of chaos? (Universe & Cosmology & Laws & Anthropic Principle & Chaos) Stephen Hawking’s Grand Design: The Key to the Cosmos
2,765. The tiny electrons appeared to be defying the laws of physics. (Universe & Electron & Laws & Physics & Quantum Physics) ibid.
