Now it’s TODAY that got to know that my doubts about thermodynamics and electricity were genuine. It took so much (I mean it so much) time to accept electricity as just another form of energy and not something magical. Same with thermodynamics, it took long long time (and finally it was Planck) to understand that heat is really a form of energy
I used to feel tha I was dumb you know bcoz whenever my book wrote “heat is the form of energy” , “electricity is the flow of electrons” I used to get so much hurt bcoz I couldn’t understand these things (you all know understand is not same as accepting the things).
My post was closed but in addition to that it was deleted.
I was communicating with a fellow by the name of Frobenius on my post.
Hope he sees this.
I will like to discuss why the post was totally deleted.
I don't understand why the reaction was so 'STRONG' that my post had to be deleted.
Hope t...
The question was Is tension a conservative force
I am getting down votes on my first answer on physics stack exchange I am not sure about the reason.
I had explained the doubt using an example of a pendullum....
Could you pls have a check if my answer was relevant to the question? Or was there ...
@ACuriousMind I added a 'closure' to my post, connecting things to physics and making it a bit more appropriate for a posting on here. Thanks for the help, that answer cleared my confusion
@Slereah would like to discuss this with you sometime, not totally following your musings, have questions on that, but think there is a solitonic version close to what you are inquiring about, an old conjecture of mine that think is on the horizon of testing/ experiment/ manifestation/ aka result(s). also believe that you would have much of the background required to extract an imminent breakthrough in the area with some not herculean effort... :)
@Slereah honestly am very excited by your ideas, have outlined similar ones over the years, came up with this idea many years ago, have been waiting for fluid dynamics software to evolve to the point its possible to simulate, that day is now probably here and has been for a few yrs... aka ripe for discovery™
@Slereah :( (sigh) this is near to some of my life work... implore you not to drop it (casually), it is vital + monumental, you raised the issue yourself in a question, maybe my +1 is the only one on your question...!
(know the feeling...!) life is what happens while youre making other plans™ ps at least read the quanta link it might cheer you up some, it did for me! :) quantamagazine.org/…
@dsm You're welcome - this question exists somewhere in that grey area of "motivated by physics but kinda just pure math" where it's always ambiguous which of the two sites it should go on, so no worries
@EmilioPisanty Fun fact - you voted to leave closed in at least one of the reopen reviews yourself
I seem to have some misunderstanding of $PdV$ in the first law of thermodynamics.
$$ P dV = T dS - d U $$
I have a ballon. I apply some work (or change the temperature inside the balloon). Now, there are $2$ ways I have to describe the change in volume.
Measure the change in volume in real sp...
Background
I had an idea to write time $dt$ in the first law of thermodynamics. So let us proceed with the $1$'st law in differential form:
$$ dw = T dS - d U $$
where $w$ is the work, $T$ is temperature, $S$ is the entropy and $U$ is the internal energy.
Now, let the work be in terms of pres...
@Slereah lol! just want to say 1 more thing as motivation/ pitch. plz dont abandon it, treat it cavalierly or flippantly. isnt there something in future of physics worth expending energy for, even fighting for? lets continue to talk on it. think of it as once in lifetime opportunity. think the next einstein is on the horizon, and it will be on (basically) a solitonic model of atoms/ quantum mechanics. all the outlines are already there. it could just take 1 guy (or lady!) at this point...! :)
Prepping for student labs next week and am confusing myself
Goal is to test what happens to a rubber band as temperature increases
A neat prediction being that, if you hang a mass on a rubber band and heat it up, then it should contract rather than expand
A way I was trying to test this was to place the mass on an electronic scale and attach a rubber band from above
So that the restoring force would be the actual weight less the scale weight
My intuition was: rubber band heats up (using a hairdryer), so it tries to contract (becomes stiffer). Hence the restoring force goes up and the scale weight would go down
But I tried it, and as best I can tell the scale weight -increases-
@Semiclassical You should make yourself look really disheveled. Come into class acting really eccentric, and use this lab to prove that science is a lie and that you've seen through it finally.
