perturbation theory, variational principle
Hello everyone, I'm new to this place. This is cut-and-pasted from another forum; one of the people over there directed me here. Any help would be appreciated. (I would like to note before you read this that my homework is in fact complete; I'm not...
When i was a kid i read the first book on hitscock the 3 investigators Bob Pete and Jupiter the castle of terror where everytime they would go to the castle they would be terrify, in the end an old movie star would have been hiding in the castle and scare people by using a certain no audible...
The images below are scanned images of work for one of my assigned problems in Calculus 2. Right now I am only concerned with integrating in order to find a position function (ignoring the constant of integration for time being).
How does it look? I am checking my work with Maple 10. I do...
My teacher for Physics hns proposed an extra credit bonus if anyone could answer this question dealing with a pendulm. Why does the pendulm move as if it had a mind of its own. Refering to the circular motion the pendulm starts making after a couple seconds. When the pendulm is released to go...
Can any of you out there explain how this works. I tried it a dozen times. It seems to always work!

is it possible that the universe has a mind of it's own, is it possible that it thinks in it's own way.
we know that information passes thru energy and the universe is full of energy. we may never be able to tolk to it, just like a tree will never be able to tolk to us, but i believe that it...
So I'm on my school's debate team. The topic we're preparing for is stated as the following: "Resolved: In the United States, public high school science curriculum should include the study of the Theory of Intelligent Design." This is my case affirming the resolution, I'm arguing ID should be...
Is it possible to say that we are not a bi-product of some extremely advanced civilizations technology, and we are just biological computers... I really don't like this idea, i just had this pop into my head one day and me and my friends started discussing it, and we came to the conclusion that...
Aghhh.. I just had to reinstall my windows because I was having some problems with it, it´s a windows xp, as I try to reinstall windows, it seems to go fine, and it deletes the old files, and prepares for windows installation, then it does a restart and then I´m back on the windows setup screen...

Can you perceive the fact that there is no end to space or the thought of God always being here and always will be or maybe the thought of there being nothing it can't be nothing it has to be something even being nothing its something,just like there has to be an...
I was bored so I am deciding that since I am only at the level of undergraduate real analysis, i wonder if anybody could solve this problem. In the movie it said that it would take someone months or many yrs or even a life time. Wonder if this is true or not?

As I sit here working and popping in on PF from time to time, I find myself busting at the seams and unable to keep this to myself any longer. According to those who would know [and have the contacts], after twelve long, often gut wrenching, once or twice terrifying, always sleep deprived, often...
I know, I'm years behind the rest of the world, but I just saw this for the first time. I've been wondering what the problem is he writes on the board that Jennifer Connelly tries to solve.
Their view seems to me 'computational.' They are associating thinking with computation and think if you just get nanotechnological about it, you can achieve consciousness and thinking.
Seems to me, this is similar to thinking that the universe is just a computer simulation of 'physics'...
What is your iq, 120, 130, 140, huh ,well that's nothing, i am so intelligent my
mind fills all of spacetime, is it any wonder then that i seem a little dim locally
with a mind spread so thin.
Hello!
What I'd like to ask is, whether there is a mathematical theory of consciousness in development or any promising serious research projects in describing conscious process mathematically or physically with sufficient mathematical background.
If, in fact we have to rely wholly on sentience in order to interpret our world, why should we deem sentience circular? If so, then our attempts to define who and what we are -- or, for that matter, anything -- is worthless. And, while we may stress the need for "empirical evidence," who or what...
What movies, animations, paintings, novels, poems, songs, etc. have you come across that transport you 'inside' someone's head? That is, what artistic portrayals have you seen or heard that effectively communicate a sense of what it is like to experience a certain set of perceptions, thoughts...
I am having an argument with someone else, and I want to see what you guys think.
I believe that the mind perceives what it wants to percieve, and that your reality could be completely different than someone elses. for example:
in person A's mind, or reality, he is talking to person B...
Can thought move or effect matter? Thought is said to be subjective, insubstantial, with no physical existence or extension. The ability for physical matter to be effected in any way by pure thought at first glance seems to be an absurd impossibility. Yet it happens everyday, virtually every...
As is well documented the Defense Advanced Research Projects Agency is funding many progressive biotech research programs.
One such program involves Brain Machine Interfaces and Muti Micro Electrode Arrays.
Some people think that there is a hidden agenda of attempting some sort of mind...
I've been thinking about something for quite a long time now. A muon can decay into two electrons, right? Since the spin of the muon is zero, the total spin of the elctrons must also be zero. That means one of the electron has up spin and the other one has down spin. According to the Copenhagen...
For better or worse, for the thrill or the terror, what do you think are the most mind blowing jobs?
At least one on my list is that of the helicopter lineman.

The Mind of Man
There are many of us here at the Physics Forums who seem to think that the mind of man is nothing more than an emergent property of the electrochemical processes that go on in the physical brain; that any computer of sufficient size and complexity would develop...

How'd you do? :-p
I'm coming to a realization that i really don't get how to do integrals.
i understand the basic concept, it's an anti-derivative. when you evaluate them, you sub in the values that you want to evaluate, and subtract them bottom from top.
i also understand that when you integrate, you get...
Speed is = to distance over time.
That is fine. but what happenes when you reach speed of light? your time would =0 therefore you would have 0 infinet speed. :confused:
These are just the things that I of last night whlest I was delivering Pizza.
Can some one clear that up for me please?
I'm currently reading "Angels and Demons", by Dan Brown - the book is mediocre, but enjoyable, in case you're wondering. Anyway, I perused a sentence that stated the following:
"Langdon felt a trace of self-preservation grip his unconscious mind."
How can someone be aware of what is...
Consider the circuit shown in Figure P28.9. (R = 33.0 .)
The question ask me to find the current flowing through the 33 ohm resistance and also the potential difference between point a and b.
I consider the 10, 5 and (33+5) to be parallel; 33 is in series with 5.
So the equivalent...
The Origin of Mind: Evolution of Brain, Cognition, and General Intelligence, 2005
Hello,
I liked the book The Origin of Mind: Evolution of Brain, Cognition, and General Intelligence, by David C. Geary, 2005 because it not only discusses some of the latest research on human intelligence, but...
I know this might be a biology question. But I think this requires the problem solving minds of people in physics.
The population of the wolves influences the change in population of the mooses. When the population of the wolves increase, the mooses' population also increase. From the...

When Descartes wrote:
"The mind exists just as long as there is a consciousness, which is not an attribute of matter"
was he saying that consciousness (and the mind) can continue even if the material body ceases to exist?
I am quite certain that he believed the reverse to be true, that...
A train is moving relative to Earth at such a high speed that the clock on the train slows down to half rate compared to clocks on earth. A rocket is launched in the opposite direction train is moving to such a high speed that the clock on the rocket slows down to half rate compared to the clock...
i was just curious about this, well here goes.
could the problem that doctors face when working with the body be a direct result of forgetting to include the mind within the process. i mean, could the reason why we haven't had breakthrough advances in human regeneration and what not, be a...
Okay... I am pretty sure this isn't a paradox, so my
reasoning must be flawed somewhere.
Could someone tell me where I am going wrong?
Consider 2 electrons, traveling in straight lines,
parallel to each other, at the same speed v, in
the same direction. An observer in a stationary...
I think every action of the mind, as in conscious the mind can be explained to the most basic instincts. You guys give some actions and ill try and explain down to the basic instincts
