Hi everybody. There has been a thread about this on physics forums, where the Fourier transform X(w) of x(t) volts (with time units in seconds) could be considered as volt second, or volt per Hz. So when we see tables of Fourier transform pairs, we might see Fourier transform plots associated...
Hi Vagn! Thanks so much - actually, incredibly much - for your comments about this. I had always been trying to understand this kind of thing. Thanks for helping me to understand the concept of minority charge carriers. Greatly appreciated!
Hi all, this question comes from an old related thread .. https://www.physicsforums.com/threads/help-in-semiconductors-minority-and-majority-carriers.613598/
I'm also interested in the definition of these 'minority charge carriers' in semiconductors.
I don't understand the explanations in the...
Maths is a discipline that has evolved, beginning from the time when somebody needed to start adding, and subtracting. Then later people discovered multiplication, division, and exotic features of working with numbers. And this discipline can be applied in conjunction with other disciplines to...
Time does exist...it is a working construct that actually is demonstrated to be useful/practical in our society. The future does exist, because if you're still thinking in 1 second from now, then obviously you can assume that there is a future in another 1 second after that...and so on. About...
No... not 'WE'...but 'YOU'. It is YOU that constructed this scenario about 'WE'. If you're going to talk about 'we', then please state which people that you're representing...just to be clear on this. You appear to be creating your own imaginary impressions of people in your own mind - conjuring...
You don't need to prove it. You just know it, because humans just defined 'time' by measuring something that's related to motion...such as how 'long' you have to sit around for when something rotates a full cycle around something. Or how long it takes for something to rotate some fraction of...
In starwars, the laser bolts from tie fighters and x-wings can be seen from side on. Anyway, we still don't understand 'energy'. Right now, we just define things like 'particles' and 'waves' because we observe certain things acting as a discrete bundle or unit when moving around, while other...
The only problem, OOW, is that you don't understand the paradoxical situations. I have no problem with the paradox. I only find it interesting. And I also find it interesting how you brand things that are too intellectually challenging for you as 'meaningless'.
Actually, you are thinking like a fool. I mentioned on many occasions that we all don't know what the deal is with the universe. I don't believe that the universe was NOT created, and at the same time, it appears that the universe 'popped out' from 'nothing'. Now, how that happened...is beyond...
No ...OOW... you're wrong. This just goes to show that you don't understand the situation. If I believe that the universe was created/formed and that it was not always around, then there lies a great question... how did it become abundant - given that the 'universe' the I'm talking about...
robert...I have definitely grasped the definition of infinity. The issue here is not our understanding of infinity, but the paradoxical situation. The paradox is : things are always created...but yet, some people assume that the 'universe' is 'infinite'. So here, there is a direct clash of...
Imagining it was already/always there is an emotional feel-good fantasy. Which is why there is a paradoxical situation on hand. We won't allow you to deviate from the fact that energy is a 'resource', and according to logic, resources are formed...in some way or another. You already know this...
I have a good opinion Robert. I - too - also hope that OOW keeps an eye out for future possibilities too.
Actually, Robert, when one assumes there is something, then - naturally - that something must have been formed or produced somehow or another. Don't worry about 'time' robert, because...
The thing here is that: you fail to understand that there's a possibility that energy was not always abundant. And you also fail to understand that there's a possibility that all resources (which includes energy and its possible constituents) was not always abundant/there/around. Plus you also...
