*sigh* Didn't your mother ever teach you that it's impolite to laugh at someone? If you can't detect sarcasm, then perhaps it's my fault for assuming that the internet is a good conductor for dry humor. In any case, there actually were a couple of articles published about this, though they're a bit lackluster at best. http://islamonline.net/english/scie...article04.shtml is one.

Sorry, I was reading in a hurry, and sometimes people actually mean stuff like that, so I didn't notice you were joking. That site is not joking though, or am I mistaken again?

The Roman Catholic church, the greatest exponent of Christian existence in the world, admitting they're wrong? A reference if you please. Galileo never talked about evolution. Evolution is Darwinian theory. That's much later than Galileo. So what did the church admit he was right about?

Sorry I forgot to mention it wasn't directly related to evolutionary theory. They admited they were wrong about the fact that the Earth is orbiting around the Sun. It was just an example to show a church latency in admiting issues they were wrong about. The pope himself apologized for the mistake and it was on tv.

And how did Orwellian arithmetic come into play here? I was saying that it's sketchy at best. You're suggesting that it's so incredibly precise that we should follow it with complete and utter surrender and devotion. Right, so how many times did the theory get adjusted over the past hundred years? Pattern recognition would suggest it will continue to do so until it is perfected, and I honestly doubt we've perfected it. And yes, the theory is always right, even when it supported such notions as polar shift (Sarcasm again. Sorry). I never said the theory was completely wrong, I just refuse to believe that it is 100% right. Reread the posts before you reply.

Ok, it was an exageration, but I said almost. I meant that as an example to show that no theory can be completely proven, but that sometimes it makes enough sense that it doesn't have to be questioned. The theory of evolution may not be proven in every single aspect of it, and some minor details about it may change, but in general, it will change very little.

But classical physics isn't a completely discovered area either, now is it? How many times was the value of G changed before it attained its current 6.67x10^-11?

That's just because of measuring imperfections. Maybe some more things will be found in classical physics (like recent detection of the fifth force that acts as antigravity, but is so very weak that it is only visible on intergalactic scale). Still, those discoveries won't change much the current laws of classical physics.
quote:
Familiar with the double slit experiment? A single-burst photon is emitted, therefore the results on the screen should be either the projection from one slit, or another. Instead, you have a grating pattern. This make sense to you? I think David Deutsch is the only scientist (works on quantum crypto. Belgium, iirc.) who can understand this stuff even close to logically. Two interpretations exist that explain it. Multiple-worlds, and Schroedinger's. Multiple-worlds interpretation states that when the photon is released, the universe splits into two, and interference between the universes is what causes the grating on the screen. Schroedinger states that all possibilities are existing until one is observed, whence all the other universes are destroyed (this is the cat paradox he is so famous for). And this makes sense? Indeed that quantum physics is what takes care of the miniscule aspects of the universe, but how can you have a qubit that can occupy more states than one, since qubits can be either a 1 or a 0, or both, or neither.


I'm familiar with those things, and I agree that the theories here are hard to understand. But again, they don't dissaprove classical physics, only make cp laws generalizations of the actual quantum physics laws.
Btw, correct me if I'm wrong, but if it has both states 1 and 0 as you said it can, then it does occupy more than one state, does it not?

quote:
You say that things will make sense eventually. Bad idea to state definite claims for an indefinite future. It seems a bit... ambitious.

Well, so far they did. Not much is known about quantum physics yet. Remember how many times there were theories like flogiston and ether, which were later dismissed for completely different and more logical theories. Of course, it may not be so, and in the end it all may not make any sense at all.

No need to apologize. Yeah, the site is serious, but the scientific thinking behind it isn't exactly perfect. It has some decent claims, but I don't think it's 100% valid. In either case, I haven't studied this aspect fully, yet.

Ahhh, alright, I see what you mean. Yeah, it's pretty hilarious to have them admit something like that in the 1990's essentially discrediting them further and making them look bad.

I see what you mean, and it makes sense. I think you and I are saying the same thing in different words. You, that although no theory is perfect it can be followed because it is nearly complete. Myself, that although a theory is nearly complete, no theory is perfect.

Won't change, that's for sure. I'm actually eager for things like antimatter, neutron stars, event horizons, etc, to be studied further.

Well, it doesn't occupy both states at the same time, per se, but theory states that both states exist, until one state is observed, in which case the other states no longer exist. Basically this is what would allow a quantum computer to crack a 4096-bit RSA key in 1 minute as opposed to 15 times the lifetime of the universe. What would happen is that let's say you have 16 qubits = 2^16 states, thus creating 65536 computations. So if you have a password that needs to be cracked and there are 65,000 possibilities, then a 16-qubit computer would crack it immediately, by separating the universe into 65536 universes, finding the correct password, and destroying the other universes. So far we're at a measly 7 qubits, but this was over a year ago at one of Princeton's labs, so I'm sure we've advanced further since then.

Haha, precisely.
