A simplification of Einstein's 1905 paper On Mar 29, 5:49 pm, Dr J Walker <"Androcles"> wrote: "Hence if x' be taken infinitesimally small", @tau/@x' + 1/(c-v) * @tau/@t = @tau/@0 + 1/(c+v)*@tau/@t And just what is @tau/@x'? It denotes the difference in clock settings, @tau, of two clocks of the moving system that are @x' = @(x-vt) apart a... 2 Apr 2010 21:30
Unrelenting Time Our units of temporal measurement, from seconds on up to months, are so complicated, assymetrical and disjunctive so as to make coherent mental reckoning in time all but impossible. Indeed, had some tyrannical God contrived to enslave our minds to time, to make it all but impossible for us to escape subjection to s... 30 Mar 2010 08:19
any injective recursive function inverts the order of infinitelymany numbers Dear all, I'm struggling with an exercise on recursion theory. I'm trying to show that for any injective recursive function f there are infinitely many numbers whose order is inverted by f such that m<n but f(n)<f(m). I'd be grateful for any hint, or reference. Best ... 29 Mar 2010 16:58
_recalibrated_ Boltzman's constant * gravitational constant = Planck's constant #547 Correcting Math Archimedes Plutonium wrote: (snipped) I am beginning to think that Algebra is what the units of definition are in Physics. For example in Physics velocity is m*s^-1, and acceleration is m*s^-2, and force is m*a. Now if I were doing say mathematics instead of physics, I would be saying that ... 29 Mar 2010 13:38
set theory intersection is multiplication, Uncertainty Principle is intersection #546 Correcting Math A wrote: Isn't the probability of both of two independent events occurring--the intersection of the set of outcomes in which event A occurs with the set of outcomes in which event B occurs--exactly the probability of event A occurring multiplied by the probability of event B occurring?

Systematic begging of questions by scientists revealed by Jones: "Are they human or monkeys?" and: "Do they rattle bones?" asks Jones of philosophic usenet group: Atheists ignore him in unusual display of perspicacity On Mar 29, 12:25 pm, John Jones <jonescard...(a)btinternet.com> wrote: Immortalist wrote: [1] - A scientist, in the broadest sense, is any person who engages in a systematic activity to acquire knowledge That begs the question. It begs the question because the term "systematic" implies what is c... 29 Mar 2010 08:02
TWO FOR ONE AT PIZZA HUT Pentcho Valev wrote: Theoretically, the null result of the Michelson-Morley experiment can be obtained by assuming that: (A) The speed of light varies with the speed of the light source (c'=c +v); the principle of relativity is correct; there are no miracles (length contraction, time dilation). ... 29 Mar 2010 06:56
What makes a good scientist? There are only two kinds of scientist. One kind is the monkey-scientist. The monkey-scientist is noisy and leaps from stone to branch posturing, grinning and gibbering to onlookers, who are awestruck by this real-time display of science in action. The other kind of scientist is the bone-rattler. The bone-ratt... 5 Apr 2010 08:18 |
