String Theory and Quantum Physics.
    #2150022 - 12/01/03 05:00 PM (20 years, 2 months ago)

I am looking for recommendations of books in both subjects. Also, any other book that tries to explain the universe and also may tie in alternate dimensions, consciousness, etc.

Thanks!

I figure this must be intended for the science forum.

Any book that tries to relate string theory etc, to conciousness is going to be full of shit. People hardly know what conciousness is, let alone how it relates to the nature of the universe.

I think we should leave this here for a little bit, see what people have to suggest regarding "to explain the universe and also may tie in alternate dimensions, consciousness, etc."

As far as the string theory and quantum physics, this thread will most likely be moved soon to Science and Tech forum.

the only book i ever read on string theory was "hyperspace" by, michio kaku. it's a few years old but i liked it. kinda heavy on the metaphors though.

It's a big long documentary about string theory. It's based on the book by Brian Greene you mentioned.

The Elegant Universe by Brian Greene
The Holotropic Mind by Stanislav Grof
The Holographic Universe by Michael Talbot
The Tao of Physics by Fritjof Capra


The first book deals with string theory.
The second and third tie science to mysticism and alternate dimensions and consciousness.
The fourth book ties mysticism to the broader aspect of physics.

Good luck on your journey.

i have a quantum physics question.

the position and velocity of a particle cannot be precisely known... we measure these things in terms of tendencies and probabilities.

my question is... is it that a particle hasn't actually got a real precise position and velocity at any given moment, or is it just that because of nature of the act of observing one, we just cannot know what they are?

or is it both?

I think most physicists today think that the particle actually does not have a specified position/velocity...it's not just that we can't measure it. This is called the Copenhagen Interpretation, as it is the interpretation of quantum physics that came out of...you guessed it!...Copenhagen :smirk:

Personally, I think it's a false interpretation. Just because we don't know specifically where a particle is or where it is going (due to our measurement) doesn't mean it isn't specific.

I think we are trying to interpret an infinite situation with finite qualities of understanding.

As long as we pretend this is not the case we will continue to experience/observe contradictory information. It is this information that exists between our modes of understanding, of course it makes no sense, because we have no sense to understand it.

Mushmaster has a good question there. In the Uncertainty Principle paper written by Werner Heisenberg in 1927, he seems to answer this question quite explicitly at two distinct points within the text. At one point he says " The more precisely the position is determined, the less precisely the momentum is known in this instant and vice versa." He is of course refering to the simultaneous determination of position and momentum of a dynamic subject, this principle also works when applied to energy and time.
It seems that when Heisenberg says the values are 'determined' or'known', he means to say that there are exact values, but one or the other will be uncertain to us.
The most famous scientist to stand in opposition of uncertainty was Einstein. Heisenberg seemed to back up the theory that the nature of the act of observing a particle was indeed the cause for the uncertainty when he went up against Einstein at a dinner in 1930. Einstein had devised a thought experiment he believed disproved the uncertainty principle. The experiment involved the emission of a particle, either a photon or an electron but I can't remember which.
Anyways, the particle is to be emitted from a box with some sort of shutter device which limits the particle emission to just one single particle. When the emission occurs, the time is measured, then the box is weighed to see how much it had changed from before the emission. Remember how time/energy is equal to position/momentum in the uncertainty equation ? dx*dp>h = dt*de>h
By weighing the box, the energy is measured since e=mc^2. This would mean that the energy and time had both been determined!
Heisenberg found his answer before the next days' end. He found that when the particle is emitted, a force is likewise applied to the box itself which makes the energy measurment less accurate, it is uncertain. This answer hints toward the nature of observation as being the reason for the uncertainty.

However, in another part of the aforementioned uncertainty paper of 1927, Heisenberg relates a different understanding of the principle. He says," I believe the existence of the classical 'path' can be pregnantly formulated as follows: The 'path' comes into existence only when we observe it."
This is a shocking statement which touches the heart of quantum physics controversy. First allow me to clarify why this statement by Heisenberg implies the position/momentum of a particle may not exist as a definitive value.
The path he talks about here is the path which Schrodinger's cat or a particle through a filter would take. What Heisienberg says is that the cat or the particle are in a state of superposition, that is the cat is dead and alive and the particle is in more places than one.
We now know that one particle causes interference with itself, or in other words it is in a superposition. A single particle as we think of one would not cause interfernce with itself, only waves have the property of interference.
So when you measure the position of a particle, the superposition becomes one defined position. The final position is determined by probabilities along the 'wave function'. (To this, Einstein said the famous words, " God does not play dice with the universe" )
It is apparent from Schrodinger's wave equation that a defined position exists only when it is measured or observed. This of course brings many more questions that answers, as any good scientific theory should.

I do hope this thread sparks more interest on the subject

A sub-atomic particle is made of a # of strings that curl or slide around a central string. An electromagnetic string is one dimensional, just as a string of matter. The central string and the surrounding strings pass through a questionable number of dimensions that are slightly larger than Plank's length. As they pass through, the strings curl and some reconnect with there self. Within the center of a curled string is a central point of gravity. This center of gravity causes the particle to remain as a particle. There is multiple points of gravity because some strings curl and slide. However the central point of gravity does not exist in a specific dimension, but in all dimensions. Since the number of dimensions is questionable and exist in any given point; there is no specific point for a particle. I think vibration of string determines velocity. Vibration changes in each dimension, so there is no specific velocity of a particle. However velocity can be measured in waves, as vibration is the distance in height and length between peak and trough of a wave.

Also all around us electrons are appearing, but being cancelled out at the same instant they appear by the positron; and that is definitely uncertain.

I'll second that recommendation of The Elegant Universe. The PBS special based on it is really dumbed down, however. I don't recommend that.

It appears you have the same lamp as I, and a similar understanding of photography. I promise you, as far as I am aware, I created the image independantly of ever seeing or hearing of your avatar.

I've had this same one for a couple years now, with this and an older account (named HateCamel--someone else is using that now, go fig). I'm only an occasional poster though, so it's no surprise if you haven't seen it.
