If you think that is incorrect, it should be easy for you to name a theory that was validated by multiple, indendent, reproducible, experiments and later discarded. -- Jim Pennino Remove .spam.sux to reply. |

No, he appeared to be referring to all theories: "Hypotheses are discarded all the time, theories aren't." And, I'd say that his statement is true, almost by definition. Why? Well, it's because scientists don't upgrade a proposal from something generally called a "hypothesis", to something called a "theory", until it has survived quite a lot of technical challenges and numerous attempts to find experimental evidence which disproves it. In other words, if it were easy (and quick) to disprove it, or if it didn't have substantial predictive power and verifiability, it never would have been called a "theory". Hypotheses are born in large numbers... and are often easily slain while they're still at the "hypothesis" stage. "Theories" are the ones which are still marching along, churning out useful predictions, after many assaults. -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

Just to get you started, mind you: http://en.wikipedia.org/wiki/Obsolet...tific_theories Let's do the physics ones: Aristotelian theory of gravity: no experimental confirmation; discarded. Classical mechanics: experimentally verified; superseded and still used within appropriate boundaries. Classical electrodynamics: experimentally verified; superceded and still used within appropriate boundaries. Ether: no experimental confirmation; discarded. Caloric theory: no experimental confirmation; discarded. Emitter theory: no experimental confirmation; discarded. Persistence of vision: no experimental confirmation; still debated. Let's do astronomical and cosmological theories: Ptolemaic system/Geocentric universe: no experimental confirmation; discarded. Copernican system: no experimental confirmation; discarded. Newtonian gravity: experimentally verified; superseded and still used within appropriate boundaries. -- Jim Pennino Remove .spam.sux to reply. |
