Ya that was more for making a very simple calculation assuming minimal energy and everything was a point particle (very classical approach). Reason I was asking how QM handled this differently. I can understand that Gauss's law causes ∇E = ρ/ε where you have the distribution ρ = 0. Thing is...
My question basically is how is it considered nuetral if the electric field potential outside the electron radius has points that can't be equal to zero? according to coulomb's law. Simple fact is that because charge is inverse squared to distance that being closer to the electron means you will...
My question is this. I have been taught in every textbook, physics lecture, and chemistry lecture that the net charge of a stable atom is 0. The result of that should be a null electric field. But looking at any model of an atom since the electrons are spaced out significantly from the nucleus...
1. Yukawa Potential
So reading about the yukawa potential I notice that the constant k is related to the inverse of the effective distance of the force from what I've been reading. Thing is everything I read about the strong force states it has infinite range but simply has a maximum potential...
ZnO is a semiconductor material that naturally is n-type without doping. Thus it will have a good conductivity because it allows easy transitions to the conduction band (what it means to be n-type).
These slides go over it...
Reading about the strong force and the residual strong force I'm a bit confused about the interaction. Largely it keeps mentioning it the result of particle exchange and mentions that it has infinite distance, but that the residual strong force doesn't have infinite distance. However, it doesn't...
Assume you want this to be 100% passive.
Imagine an auditorium (in fact read about auditorium design). Geometry is going to be the factor for optimal focusing. Then you want to design whatever you do to have a resonance frequency near the Frequency of sound of the engine so it reverbs with the...
Ya been reading the typical way is lensing of an electron beam. They trace out a larger version (micron to 10 micron accuracy) but have lensing effects that convert that to nanometer accuracy.
Light is diffraction limited at visible wavelengths giving maximum accuracy at about 1 - 5 x 10-7...
I don't know 150MPa is really high. As in you'd have to be careful even with cement.

21755 psi. That would break apart a cement mold. Is there a reason you have to use this mold? Sounds like recreating it out of stronger...
Reason two vehicles traveling at 50mph don't add up to 1 vehicle at 100 mph is because energy is related to velocity SQUARED. So 1 vehicle with 100 mph will have more KE than 2 equally sized ones with 50 mph. What stops you in a car crash isn't your brakes it's the energy of the two cars...
High temp and gas is a problem for polymers if your going to be vaporizing organics. You'd be restricted to PTFE hose and all ptfe hose has steel wire mesh reinforcement. Electric field could pose problem though, I'd check with manufacturer and ask what they think. It would for sure keep you...
Earth's gravity is actually really non-constant, but not because of increasing mass.
The Earth isn't a perfect sphere so your latitude has a pretty big effect on the total gravity you experience (the greatest is at the poles). To the point without exact measurement at your location you actually...
Those specs aren't that high, your looking for either a 'high temp' polymer like teflon (they don't melt until 350-450F typically) or a ceramic.
You can also just use normal pipe with an insulating wrap depending on your need. That would probably be cheapest. Next step is teflon coated pipe then...
Solar driven for steam means Parabolic dishes. So you'll have to do something like a solar oven to boil it. Possibly even a cheap half-ball lens ($10-20) with the focal point on a heat exchanger section of your pipe. Large parabolic dish focused on a mirror directing to your ball lens should let...
Few questions:
1. How are the masks made for sub micrometer level accuracy. Laser? Namely even with lasers how would they guarantee the positioning system to that level of accuracy to aim the laser how they want?
2. Any recommended books?
