Thank you both, greatly, for your replies. They are both of help and, I appreciate your time.

If I am using radar to determine the distance of an object from my transmission source by reflecting my radio waves off of the surface of the object and recording the time at which they return and, I want to encase my detector to protect it from the elements, how do I select the material with...

I hadn't thought about that. Thank you. I'll look into it.

Carlgrace, thank you for your reply. I really appreciate the input. I've been told that with a B.S. in physics, I am eligible for an engineering position but, that does not seem to coincide with the attitudes of employers, from what I have seen. Can anyone recommend any certifications for...

I will graduate this spring with a B.S. in Physics. Are there any tests I can take to get a license or a certification that will make me more appealing for an engineering position? Could I take the test to become a P.E. without actually having a degree in engineering? Can I take something...

Very interesting. Thank you, very much, for your reply.

Adiabatic process: a process where no heat is gained or lost. it is my understanding, however, that this is a hypothetical system. There is no insulator on Earth good enough to allow this system to exist, except to approximations. So, what happens is you have a system where whatever is...

Why is it that, when using a Kater's Pendulum where the pivot points are fixed and one weight is adjustable, it is acceptable to discard the factor of the difference between the two distances of the individual pivot points from the center of gravity (1/(l1-l2)) in the following formula? T^2 =...

Using the formula 1/f = 1/object distance + 1/image distance, in the instance where you have two plano-convex lenses glued together on their flat sides, what does it mean if your image distance from the first lens is negative? is the image in front of the second lens or behind the second...

Thank you, all. Your time and help is immensely appreciated.

Why does the laplacian vanish for harmonic functions? Can someone explain this in physical terms?

Well, I guess even taking one segment of infinitely many they are all planes perpendicular to the propagation of motion. I'm sorry. My momentary misunderstanding. Thank you, lost conjugate. It is much appreciated.

But, only some things travel perpendicular to the direction of propagation, correct? Doesn't light travel in 360 degrees?

I'm having some difficulty with quantum which stems from a weak math background as a shaky foundation upon which to start with an inherently difficult subject. So, if anyone would be willing to help me with some conceptual obstacles and thought exercises, I would be very grateful. These are...

What does it mean to say that the fundamental relation of thermodynamics is homogeneous first-order? I struggle with the abstraction of mathematical definitions and, I'm really seeking more to understand the relation of the physical variables of thermodynamics. Why are all of the variables...
