I have this magical "blackboard" where the equations I write becomes true. There are several layers of equations, i.e. some are more important than others, but it is a piece of cake to add a new equation ... or delete an existing equation. There are equations for many things, also for the...

I remember reading about an experiment a little earlier this year that sent very short laser pulses (atto second or there about) down on an atom in order to see the electrons orbiting it. Normally we consider the electron a smeared-out wave, but they acutally saw/measured the electron's position...

IMHO we won't get a grip on the double slit experiment before we understand the wave function (wf) itself :frown: . When the wf is not collapsed what value(s) does it have? Superposition says theory, but that implies a split of the particle itself. Is the universe really schizofrenic? :smile:

Orion1, If nothing can remain inside a white hole, then it cannot have mass. I'd say that the white hole bounces of the black hole. They could never merge.

If I remember correctly that calculation was debunked. To the best of my knowledge, the speed of gravity is the same as the speed of light.

Don't you guys find it troubling though that the universe on the smallest of scales is allowed to not obey the conservation of energy law (Heisenberg) while we, at macroscopic scales, insist that it must be conserved? What I'm hinting at here is that we have a "when" issue rather than an "if"...

I guess that r[i]>1/(20*z[i]) is "always" true. Then you have z[t+dt](i)=z[t] explicitly in your code.

I just read the latest Scientific American and they have an article about the proof of the Poincaré conjecture. Apparently the proof uses a modified (an extra element) Ricci flow and then the article says that the modification to the Ricci flow pops up in Super String Theory :confused: ...

Infinitely far away, because the force between the bodies is GMm/(r*r). If your question was meant to be when the force between Earth and the comet is the dominant gravitational force, well that's an entirely different question.

The most useless math I have learned so far is fraction calculation.

I think your question was more along the lines if such a program already exists? I am not an expert, but I remember reading that a program that could perform mathematical deductions had been written and that's several years ago. I also remember though that that program was hailed as a...

Isn't quantum logic an extension of boolean logic? I mean, allowing a state to be "temporarily" undefined. Is the tunnel effect not an example of normal logic not being adequate? I mean, particle A is at location X at time T1 and in the next instant it is at location Y at time T2. We can explain...

Talking dimensions like this, i.e. as if the number of dimensions might be (locally?) variable. Is there anybody who have analysed the possibility of this? It seems that our nice inverse square laws puts strict limits to such schemes, no?

I understand what you mean with your questioning our belief in logic. However, logic has taken us pretty far, so it would be strange if it could be proven wrong. I guess it could be "proven" more limited than necessary. It is "strange" that logic works so well, that our universe is logical and...

Let's resort to lambda calculus, shall we? That's where we start by defining what "true" is and what "false" is. Lambda calculus is the basis for all modern computer languages and is in fact logic put into (mathemtical) language. 1=3 is not just illogical it leads to absurdities. If taken at...
