All of you covered me with your answers thank you very much!

Hello, I was always wondering how in research centres scientists are able to apply quantum mechanics' equations to predict an outcome. I mean, let's say you do an experiment and then collect the results, how can someone use quantum mechanics to predict the outcome ,if he can? For example,in...

Thank you, that's very helpful!

So you say that its much. better to replace the motherboard, I agree. But on that laptop I had much data, could I just change the motherboard and take the internal hard drive from the faulty laptop and put it on the new one? Is there any compatibility issues I should know between internal hard...

I see, I agree that substitution is probably the only way, but there was a case a few months ago, I had a laptop which for some reason I couldn't turn on and when I could even plugged in there was no charging. I went to a laptop technician and told him to see it and that it was probably the...

I see, that's basically what my teachers told me,but what happens if you can't fix it ,or even find the problem. Worst case scenario of course must be the case where the technician makes it worse...but i see your point,thank you

Thank you very much, I understand your point,this procedure you provided is of great help.

I know,but when for example you have a laptop which has many systems inside and the pcbs are very complex,how do you know where to search,and even if you know which part is probably faulty, that section of the pcb still has too many components,how do you know which one is faulty.

Hello, I am a student in mechanical engineering and also like electronics ( repairs and things like that ),i know electronics and how to build circuits,even embedded systems,but have no clue how to repair a circuit. I thought it'd be easy,but I soon found out that trying to fix pcbs isn't a...

Thank you, i already own the book you suggested,but unfortunately Gauss' s law is only for conditions of symmetry, that's the first step in the book was to find an appropriate coordinate system,just for ease of calculations under symmetry conditions. I was covered by the above answers,thank you...

hahaha it wasnt homework

Thank you all for your answers, they have been of great help! I will put them on the test. It's really amazing to see people from all countries come together and give advice to each other when it comes to making progress, despite the fact that most countries were in war a couple of years ago...

None, I didn't need them so far to make something. The only thing I needed till now was circuit theory.

Thank you for your answer. Basically, by asymmetric capacitor I mean, like two parallel plates as electrodes and the dielectric be a sphere, things like that.

Summary: I need to build an asymmetric capacitor, but the mathematics of electromagnetics become too tough, do you have any info that can help? Appreciate it! Hello, I am an undergraduate student in engineering and I want to build an asymmetric capacitor, so I need electromagnetics which I...
