2,390. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you. (Science & Atom & Experiment & Particle) Ernest Rutherford, experiment in which one in eight thousand alpha particles scattered backwards when fired at a metal sheet of foil, cited E N da C Andrada ‘Rutherford and the Nature of the Atom’ 1964
2,394. If your experiment needs statistics, you ought to have done a better experiment. (Science & Experiment & Statistics) Ernest Rutherford
80,798. The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa. (Measurement & Experiment & Quantum Physics & Certainty) Werner Heisenberg’s uncertainty principle
63,302. The solution of the difficulty is that the two mental pictures which experiment lead us to form – the one of the particles, the other of the waves – are both incomplete and have only the validity of analogies which are accurate only in limiting cases. (Analogy & Wave & Particle & Experiment) Werner Heisenberg
2,444. If you’re doing an experiment, you should report everything that you think might make it invalid – not only what you think is right about it; other causes that could possibly explain your results; and things you thought of that you’ve eliminated by some other experiment, and how they worked – to make sure the other fellow can tell they have been eliminated. Details that could throw doubt on your interpretation must be given, if you know them. (Science & Experiment) Richard Feynman
71,887. If it disagrees with experiment, it’s wrong. In that simple statement is the key to science. (Experiment & Science) Professor Richard Feynman
91,041. It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong. (Theory & Experiment) Richard P Feynman
71,888. Nothing is to wonderful to be true, if it be consistence with the laws of nature, and in such things as these, experiment is the best test of such consistency. Michael Faraday, diary 19th March 1849
86,187. The measurement problem ... An atom only appears in a particular place if you measure it. In other words an atom is spread out all over the place until a conscious observer decides to look at it. So the act of measurement or observation creates the entire universe. (Quantum Physics & Atom & Measurement & Reality & Observation & Experiment) Professor Jim Al-Khalili, Atom: The Illusion of Reality
2,667. Science is based on experiment, on a willingness to challenge old dogma, on an openness to see the universe as it really is. Accordingly, science sometimes requires courage – at the very least the courage to question the conventional wisdom. (Science & Courage & Experiment & Wisdom) Carl Sagan
86,176. In the 1920s physicist Niels Bohr found that Newton’s Laws break down at the atomic level. The replacement Quantum Theory ... showed that the electron orbiting the atomic nucleus doesn’t look like this at all. It’s more smudged out, more like a ripple or a wave. (Quantum Physics & Reality & Observation & Experiment & Electron & Anthropic Principle) Horizon: The Anthropic Principle, BBC 1987
86,177. We have to record some kind of measurement to know where an electron is. In fact, until we decide to find out where the electron is by doing an experiment to observe it the electron as a material entity cannot be really said to exist. (Quantum Physics & Reality & Observation & Experiment & Electron & Anthropic Principle) ibid.
86,178. That by our acts of observation we bring things into existence, at least in the realm of the very small, is supported by scientific experiment. (Quantum Physics & Reality & Observation & Experiment & Electron & Anthropic Principle) ibid.
86,179. If we bring the tiny world of the Quantum to existence by our observations, do we need any other mechanism to account for the whole of reality? (Quantum Physics & Reality & Observation & Experiment & Electron & Anthropic Principle) ibid.
2,507. We have a set of physical laws that we know from laboratory experiments work; we use these laws to formulate a theory; we use that theory to make predictions, then we compare and then we compare these predictions with observations. (Science & Experiment & Theory) Professor Carlos Frenk, Horizon: Of Big Bangs, Stick Men and Galactic Holes, BBC 1991
2,508. Anything that you come up with has to be corroborated, not just by one measurement, one experiment, but by many different groups - that’s the essence of the scientific method - repeatability, rigor, accuracy and relevance. (Science & Experiment) Professor Carlos Frenk, Horizon: Is Everything We Know About the Universe Wrong? BBC 2009
48,967. French engineers and scientists are building a great scientific machine. It’s a nuclear accelerator called the Vivitron. It’s cost eight billion pounds. And part of it has come from Britain. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) Horizon: An Expensive Theology, BBC 1992
48,968. They’re working with the nucleus of the magnesium atom. The magnesium atoms are accelerated down this huge tower ... The nuclei are fired into a target also of magnesium. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) ibid.
48,969. The funding was established by treaty. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) ibid.
48,970. The first Cyclotron was a giant of its day. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) ibid.
48,971. The collision creates a tiny fireball getting close to the Big Bang at the start of our universe. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) ibid.
48,972. Quarks: five have been detected. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) ibid.
48,973. Cern costs three hundred and fifty million pounds a year ... Cern is governed by international treaty. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) ibid.
48,974. Mrs Thatcher even visited Cern to enthuse over the experiments. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) ibid.
48,975. The particle physicists are asking for funds for the next stage of their research. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) ibid.
48,976. The Americans are planning an even bigger rival. Here in Texas they’ve started construction on the Super Conducting Super Collider. (Nuclear & Atom & Particle Accelerator & Experiment & Particle & Science) ibid.
80,756. Welcome to the weird world of quantum reality: where nothing is quite what is seems ... A remarkable experiment that puts the very existence of reality into question: known to physicists as the Double Slit experiment its remarkable because it reveals two astonishing paradoxes about the nature of reality no-one can fully explain. (Quantum Physics & Experiment) Horizon: What Is Reality? BBC 2011
2,562. Cavendish probed the secrets of Nature with brilliant insights and meticulous experiments. (Science & Nature & Experiment & Great Britain) Genius of Britain II: A Roomful of Brilliant Minds, Channel 4 2012
