Ok, so temp is a measure of thermal energy, and heat is the transfer of energy? So heat is not the same as temp. Gotcha. Kinda subtle. Motion = energy is probably more in line with the observation I wanted to express in that regard. Im starting to see the limitations of that statement the more I research this also. ; - ) Bear with me guys im new to this, but I am thoroughly addicted and begin classes in the fall.

No debate here, I agree. Talking about heat in terms of motion continues to work even in respect to radiation other than thermal, and is not invalid regardless of semantics. (even as the "process" of transfer) this is not a fundamental difference in definitional at all. I understand your point that in Physics to clarify what is ment by saying heat you define it as the process. But when discussing a topic you want to make clear what is occuring. What is occuring with-in the light radiation? Even in your microwave example. How is the "heat" of a microwave determined? (frequency -- hmm makes me think motion again) How is the Energy of a Microwave Expressed? Compare two different waves? If a wave travels with high frequency giving it greater energy what does that look like side by side with a low energy wave . . . It all comes back to motion. I used the example of molecular motion becuase I thought thats what we where talking about in the example of a station in the antartic making use of a change in temp. Question? At what point does the motion of atoms become a property? At what point does the Frequncy of radiation become a property? This is nonsense. So again I miss your point, and do not see where I made such a statement when describing the enteractions of atoms as giving rise to heat, and the felt nature of temp. Breaking down things into process is how understanding occurs, that was my only point . . .

Beautifull, poetry takes confidence. It opens the door, allows us all a peek inside. I particularly liked the Turtle reference as well, and I agree with the sentiment of rhyme, and meter. The same harmony that entrances us in music makes this style of poetry all the more touching for me.

Well, are we not all Time travelers? We all move through time. If in the same inertial frame then at the same rate. If we use more of our movement through space we use less of our movement through time. obviously different than blink- differnt epoch, but still time travel. ; - ) Ahh Language

Re Black Holes (My Dumb Question)
Jean Maxwell replied to JohnB's topic in Modern and Theoretical Physics
I do not think it has been settled, this question of total mass. Estimates abound. If we had a decisive understanding of the mass, then we would also have very strong evidence to either the validity or the rejection of inflation as a standard model. Most scientists agree on a close range which seems to suggest that mass leaking from black holes into "other universe" is not occuring, but again we have not settled other questions completeley quit yet. -
teleology with out the teleology ; - ) It is not really an argument you can participate in with out placing it in the context of each of the other theories of comoslogical begginings. What is more difficult to believe in super levitating turtles or quantum fuzziness. Its actually a very deep argument. I remain very skeptical, as anyone should that holds science in high regard, however to truely debate this material requires ALOT of logic string, and being willing to participate, many scientists and hobbiest are not willing to debate an anthropic topic (pun intended) "The Cosmic Jackpot" is the book he lays all this out. Very interesting but well within the realm of philosphy due to the lack of experimental capabilities.

Yes, every day. The microwaves excite water Molecules generating heat. Motion of Atoms. Heating the molecules speed up in there movement, so regardless of how they attain there heat atoms being heated is expressed in there motion. Transfer of heat is the kenetic interactions. At room temp, air molecules move 5 miles/ minute, or the speed of sound. This makes great sense. If you raise the temp of the air, the molecules travel faster, and subsequently it will increase the speed of sound. Photons strike atoms causing them to move. Very simple very true statment, im curious what you feel about that is invalid?

Does acceleration greatly affect gravity
Jean Maxwell replied to Killa Klown's topic in Classical Physics
Well and look at what we have here. The expansion of the universe has been observed, if gravity where much different say it did function is such a way that more attraction was generated due to acceleration, or spin. What would happen is that would GREATLY alter the balance of cosmic expansion. More gravity would require a greater outward surge of inflation, or expansion to balance to what we observe. It would alter other observable phenomena such as the formation of galaxies, somthing that isnt fully understood yet, but is being studied heavily. Very intersting line of thinking however. As I was reading this post I began thinking about some abstractions of gravity. I am fairly new to physics and understand certain things less than clearly. (I hope I can effectivley explain this heh) We observe all massive bodies form shperes for reasons of symmetry, and see the heaviest of materials "sift" to the center. What IF we could organize the heavy material in a different fashion. (I know I know it would inevitably crush itself back to a sphere) But suspend disbelief for a moment and supose that we have a technology that could allow us to take the heaviest material and form it into whatever structures we wanted. What shapes could we make that would significatly change the shape of spacetime? Would it really change at all? Or would the force only be lessened, spacedout, and diffusal, canceling ect? I guess alot of the answers to this question would come from a full understnding of the nature of Quantum gravity, and the nature of spacetime. But its interesting to think about. My initial design was inverting mass from center to exterior and have us walking around on the inside of a sphere, but I quickly realized that if I used a quantum gravity thought process enteracting with a higs feild then it would not allow us to walk around the inside with a simple heavy "crust" and hollow interior. It would require massive "lumps" at intervals, and then I started to think well hell then I might as well make it a sphere, and again there is no point to the thought experiment. But then I thought well, if spacetime is fabric like, then a spiral structure with super massive beams could "twist" it enough to detect. ( Whats the thoughts on high density energy such as the lasers possed in this guys "time Machine" theory http://www.physorg.com/news63371210.html ) Also I dont really understand the fundamental reason energy could create gavity? any explaination would be awesome. ; - ) This idea is NOT original I know, but I wanted to hear other opinions, and perhaps I have not thought of something relevant that has been observed, or some geometry, Im very weak in maths, have just started my formal training. -
The issue with making use of change in heat to perform work or create electricity is that you need a closed system, to acomplish this on the level you refer to would require a huge facility to make use of the temp change to a great enough degree (pun intended) (And about heat being the transfer of energy, I think a more specific definition is heat is molecular kinetic energy, heat is the motion of atoms) I agree lets use information from a top down veiw, make it as specific as possible, then if it needs clarification the indivual can speek out asking for such clarification, I know when something interests me I will ask a multitude of questions to better understand and be able to relate it in a more practical way. I am curious about the differing range of energy that encompasses Cosmic rays, and the change in energectic reactions (in the atmosphere) from our sun as it changes from a state of low quantities of solar flare to high quantity, ( hope I stated that meaningfully teehee) Anyone have an info on the subjeck?
