[Tycho?]

I'm not particularily well versed in black holes but does this open up the possiblity of 2 way travel?

 

Please excuse my ignorance.

Umm.... what are you talking about?

We already have an astronomy forum. And since you are here trying to get new members, I would bet that the one you are posting in is a lot better than yours.

Einstien wins over Bohr hands down... Borh was definately very smart, and he certainly contributed. But Einstien rewrote the book on physics almost single handedly, and he contributed to other things than SR and GR. He actually won his nobel prize as a result of his work in quantum mechanics (even if later he didn't agree with it).

I'd say Newton should be up there, what with his laws of gravitation, invention of calculus (well, another guy did it as well, but Newton had something to do with it anyway)

This is just the discoveries that I think will be profound, you can ponder them if you feel like it.

In no particular order.

Development of Artificial Intelligence that can match a human

Understanding on the inner workings of our brain, both physical and pychological. Also the augmenting of human brain.

Nuclear Fusion as a viable power source (I hope)

Cloning/genetic engineering of humans. This is just part of the whole medicine catagory, which can include things such as stem cells, artificial or transplanted limbs or organs, immunology, and extending of human life span. Plus enhancing humans, through engineering or cybernetics.

Quantum gravity

All things nanotech, ie new materials, building techniques, medical applications etc.

Quantum computing/improvment and proliferation of computers in general

Of course, as usual the greatest and most important discoveries will be ones that nobody sees coming.

Yes' date=' logic must indeed be central. Sorry to dissapoint you on all counts Tycho. You have totally misunderstood my arguments; that is because you've taken a cursory glance and reached a super quick and super wrong conclusion. On time having a zero point? I claim the exact opposite - the whole construct of time is a mathematical convenience to measure the flow of energy. Time, length, speed and direction are derived from energy flows and not vice-versa.

As for the existence of nothingness? It ties up with our concept of zero, to have a starting point, there has to be a zeroth point (a point of total emptiness devoid of energy). In any event, what does zero really mean? If theres no measurable zeroth point ...and there's none; zero goes out the window like the mathematical construct and mental bound that it is. You have to start from an equilibrium.

C is constant for a medium, just as the speed of sound is contant for a medium. I do not argue that does not vary with condition, to the contrary, if you pay close enough attention to the papers logic, you'll find that I don't treat C as a rigid constant.

Yes, logic must indeed be central.[/quote']

 

 

Dissapoint me on all accounts? You explained remarkably little.

 

"Time tends to be addressed as a fundamental of nature, but for this to be so, time would have to have a beginning or a "zero" point."

 

For time to be a fundamental of nature does not mean that it must have a zero point. You have not explained yourself on this.

 

"No science theory or observation has proven the existence of nothingness."

 

You really havn't explained yourself on this, only talking about no measurable zeroth point... in refference to what? There is no zero point to anything?

 

"This rigid and unexplained mathematical solution has led to a lot of confusion accross mordern physics. (reffering to relativity)"

 

You didn't address this. Relativity is rather the opposite of unexplained.

Alright. Why does time have to have a zero point? Since when is relativity an unexplained mathematical solution? Also, since when has it caused a lot of confusion, any more than any other theories?

And proven the existance of nothingness? I'm not even sure what you are getting at here.

edit: Oh yeah. And why is logic central here? I would not consider c being constant to be logical. Most of quantum mechanics seems quite illogical to me. That doesn't mean its not true, and physics most certianly does not have to be logical to be correct.

Oh yeah, and it said it was published in 1997. That is not new.

"Time tends to be addressed as a fundamental of nature, but for this to be so, time would have to have a beginning or a "zero" point."

"No science theory or observation has proven the existence of nothingness."

"This rigid and unexplained mathematical solution has led to a lot of confusion accross mordern physics. (reffering to relativity)"

Plus, he didn't spell check the damn thing.

I somehow doubt that nasa.gov blast astronauts and sensitive electronic equipment into the solar maelstrom without any protection at all.

 

Anyhoo' date=' there must be a reason they use what they use re: heat shielding. Perhaps there is more info on their web site.[/quote']

 

 

Well, they do have some protection, but I do not believe they have protection from gamma rays. I dont think gamma rays would effect electronics equipment either.

There were 6 attackers with knives? I can see why nobody did anything, they were all scared. Still, man, I hate that racist garbage.

Does the current heat shield block gamma rays? I thought you needed something quite dense for that, like lead.

I sure as hell don't.

My guess would be Martin, but I believe you have already talked to him...

A single electron moving can't really be considered electricity, as there isn't really any current flow to speak of. You need a bunch of electrons moving to get an electric current.

I believe Canada is a good country because anyone can make a party with just 100 signatures and a few thousand dollars very nice system.

Ehhh, Canada's system is ok (I live there) but its not that great. I think Canada should have more political parties as well, so a party can never get a majority government, and must always ally themsevles with another party to maintain power. I would also like proportional representation. A system like Germany's, or Isreal's is pretty good.

Oh yeah, and I think the US system can barely be called a democracy at all, considering that the two main choices are nearly exactly the same.

edit: well I took the quiz (again) i got

Economic Left/Right: -6.50

Social Libertarian/Authoritarian: -6.31

On the graph, pretty much where I was last time I took it.

I dont think the actual workings of age are very well understood, plenty of theory, not so much in the more concrete department.

I saw an interesting documentry on the subject. I forget most of it, but it seemed to point out that there was a corelation in the aging of cells and cancer. Namely, that aging is a mechanism to prevent cancer, turning off cell division before they become damaged enough to potentially turn cancerous. As well they pointed out that cancers are cells that divide indefinately, and do not age. Interesting show, I wish I remember more of it.

I hope nobody makes a movie based on this.

Both. I really can't see why something would be so freaking big and not be a predator.

HAHAHAHAHAHA, oh man, I am so saving that pic, I love it.

If he's right or wrong its hilarious either way.

**shakes head slowly**

Photons have momentum of p=E/c. Whan an atom absorbs a photon' date=' it gets a momentum "kick." When it releases a photon, there is another "kick." But the directions don't have to coincide, so there can be a force on the atom. Even though E/c is small, atoms aren't very massive and an atom can absorb and emit millions of times a second.

 

The 1997 Nobel prize in Physics was awarded for laser cooling, which uses the radiation pressure concept. (Chu, Phillips and Cohen-Tannoudji)[/quote']

 

 

Huh, I didn't know that. I knew they were able to for something like a light sail to work. But boy, thats pretty neat.

I wasn't aware it was a "great mystery" since, you know, lightning is very well understood and has been for a while.

Swoosh

Thats the sound of this thread going over my head.

I dont see why an flywheel device would be needed. It should work fine without one I would think.

How does EM radiation exert pressure on something?
