is anyone of you learning Statistical Mechanics ? come and let's learn together!!!
:biggrin: haha, I am currently taking statistical mechanics in my undergraduate 2nd year. This subject is so interesting! I would like to invite you all to discuss and debate about the our understanding of...
Is it POSSIBLE to integrate C++ with WITec Project 1.88??? urgent call for help~ haha
currently i am doing a project in which i have to extract date MANUALLY from the solfware. It will be VERY tiring because the number of data I have to extract is more than 1000 times...
It is so surprising that athe Wimshurst machine can generate up tp 1,000,000 voltage with the size of 50 cm!
As I know, in order to generate such a high voltage on its 2 terminals, there must be a very large quantity of charges being "collected and stored" in the Leyden Jars.
Am I right...
usually, the solenoid we study in university text books is ideal. That is, the diameter of the solenoid is very small compared to its length.
This ideal solenoid has one important property:
The magnatics field generated (when there is current) is "ALMOST" ZERO everywhere outside the...
people said that most great ideas and developments in sciences (especially physics and mathematics) are made by young men.
For example, Einstein, Heisenberg, Newton, Ramanujan, and so on.
Nowadays, we see that most peiople get their phD at nearly 28. Do you think 28 is stilla Golden...
hi my friends!
I just want to ask, do you like studying in midnight?
I found that, I can concentrate better in midnight, and in afternoon I always feel sleepy!
For me, I prefer studying in midnight because I can HIGHLY concentrate in that time!!!
But as I know, working or studying in...
in the diffraction experiment, the light source and the slit are in the same horizonatal line.
My question is, if the light source is placed at another position which is no longer in the previous horizontal line, would we still get the same diffraction pattern?
Will the diffraction pattern...
I think your question is, why the photon does not deflect, even though it is composed of electromagnetic field.
My idea is,
because the photon carries No charge, hence it will not "feel" the external electric field.
What are the "classical Textbooks" for quantum mechanics and electromagnetism???
I want to use my vacations to study quantum mechanics and eletromagnetism.
Are there any "classical textbook" for these 2 subjects, like "Goldstein classical mechanics" for mechanics?
hi Dimitry Terryn,
here in Malaysia, usually peope start their first year undergraduate at the age of 20!
phD: 3 --5 years
haha, I dont know why the government let people here start their undergraduate study so late... ...
anyway, I am studying my...
At what age you competed your phD?
As I have calculated, I would have completed my phD right at the age of 28, is it too LATE?
I have heard that some professors completed their phD at 23 or even 21.
oh I see....
That means, along the way, the elctrons actually always maintain their kinetic energy at "small magnitude" due to collisions. In other words, the gain in kietic energy (from the battery) is always balanced out by the loss of heat in collisions, roughly speaking.
Kirchoff's law states that, the potential difference along a closed circuit must be ZERO.
Now, lets do a simple question 1.
We have a simple circuit consists of INDUCTOR and Voltage source-->V=V.sin(wt)
At any instant, why must the voltage supplied equal the voltage generated in the...
I was told that, in an simple electronic circuit (consist of resistor and battery), the power supplied by the battery must be equal to the power (heat) dissipated by the resistor.
In form of equation:
VI = RI^2 ,where V=voltage supplied by the battery, I=current, R=resistence.
thanks for your quick reply Dr Transport, I really appreaciate it.
In fact now I am so confused, about the future.
Although studying physicis is my dream, but, the 5 years of jobless period is really a difficult time for me.
I need as many imformation as possible.
Anyway, thanks so much...
I am not an US citizen, but have a plan to study phD in US.
However, I have financial problem.
My question is:
If I am awarded a phD scholarship, is there still any other "financial sources" that I can work for to earn some more money?
If I spend just enough for basic living...
Thanks to you all ladies/guys!
You have given me a clear picture of what a conductor is and whe logic behind the ZERO-E statement.
At the time I post this dicsussion, I missed one point: there is a large amount of eletron sea residing IN the conductor.
As can be understood, these...
I want to be a professor in theoretical physics, but, people said that this position is limited.
My question is, would a University recruit a excellent theoretical professor, even when there has been SO MANY theoretical physicist?
I worry that, because theoretical physicists bring NO...
Ampere's law states that,
the closed integral of B over the loop enclosed it equals uI, where u = permeability of the material and I = current "passing" through the loop.
I feel confused, because, should the current be extended to infinity?
I mean, when we have an infinite wire of current...
