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 of Science & 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 of Science) 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 of Science) Arthur Eddington, The Nature of the Physical World 1928

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 of Science & Entropy) Order and Disorder With Jim Al-Khalili I: Energy, BBC 2012

48,733. Left alone energy always seems to go from being concentrated to being dispersed. (Energy & Physics & Laws of Science & Entropy) ibid.
48,734. The second law of thermodynamics 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 of Science & Entropy) ibid.
48,735. Entropy – why was it always increasing? (Energy & Physics & Laws of Science & Entropy) ibid.
48,736. Entropy was in fact a measure of the disorder of things. (Energy & Physics & Laws of Science & Entropy) ibid.
2,582. Boyle’s List: all but two of twenty four things on this list have now been achieved by science. (Science & Laws of Science & Entropy) 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 ... ibid. (Science & Steam & Atom & Vaccination & Laws of Science & Entropy) 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 of Science & 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 of Science & Nature & Inquiry) John Dewey, Reconstruction in Philosophy
2,708. The same laws of physics apply everywhere throughout the cosmos. (Universe & Cosmology & Physics & Laws of Science) 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 of Science & Science & Cosmology & Understand & Anthropic Principle) Dr David Deutsch

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 of Science) 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 of Science & Anthropic Principle & Chaos) Stephen Hawking’s Grand Design: The Key to the Cosmos

(Universe & Cosmology & Nuclear & Laws of Science & Anthropic Principle) Professor Fred Hoyle

2,800. Supernovae would be the key to measuring the expansion of the universe and reveal how it would all end. (Universe & Cosmology & Supernovae & Laws of Science) ibid.
2,801. They could not believe what they were seeing. They knew the universe should be slowing down in its expansion, that gravity should be tugging on it, pulling it in. But they were seeing something that defied the known laws of Physics, and all their expectations. The universe was speeding up not slowing down. (Universe & Cosmology & Laws of Science & Gravity) ibid.
