Hi, I'm an engineer working on a subsea pipeline project. Right now I am working on a spreadsheet to calculate the differential net pressure on a sub sea pipeline. I am using API RP 1111 for offshore pipeline design. My question is the following.
For any pipeline with a nonzero wall thickness...
You are right to say that this would be incorrect from a physicists point of view because of the methodology. However, I guess I was looking at it from an engineering point of view (myself being an engineering student in college). Let me respond in the following way.
I understand that a change...
Okay, let me clarify this isn't for homework or anything. Purely something I thought of when I was driving home. I am not sure if there is already a solution to this problem, there probably is but I want to see how correct my solution is.
The problem is the following. Suppose I am traveling...
If you look at Newtonian gravity, there is no major deal with coordinate systems. I am guessing we use coordinate systems because in general relativity we think of coordinate systems as different frames of references and that all frame of references must have the same laws of physics. Is that why?
Say if I have a sample space 2,3, and 5. I want to find by what percent points deviate from the mean. So I would take the standard deviation as follows.
2+3+5 / 3 = 3.33
(2-3.33)^2 + (3-3.33)^2 + (5-3.33)^2 / 3 = 1.55
(1.55)^(1/2) = 0.775
So we get a standard deviation of 0.775. So how do I...
Considering the majority of the universe is intergalactic space and that light gets dimmer by the inverse square law. If you pick a random place in the universe you are going to see no light (Light that's bright enough for the eye) and hear no sound. Is this accurate to say?
Scientifically, we are just a chemical process on the the surface of a giant rock. The only reason why we do what we do is because "It feels nice". All those long hours at the university and studying. What does it ultimately accomplish? This video explains further

You know how every particle has a non zero probability of being anywhere, but what about outside the particles Hubble sphere? In other words, does is there exist a nonzero probability that a particle can travel at superluminal speeds across the universe?
I have been interested in the story of halo lately. I have trying to come up with a way to theoretically create a mechanism that kills all life via radiation in a 25,000 ly radius. (The function of a halo ring).
This is what I have so far, using millions of lasers focusing on one point...
For example, after the big bang, the only thing that decides the future is Newtons laws. However, we must take into account quantum effects we cannot be for sure what the future holds. Doesn't the same thing apply with information. How can we know the information about a system if there is...
Leptons are supposed to be eternal because they do not decay. What about if you through a lepton (say electron in this case) into a black hole. The electron gets destroyed black hole and its mass gets added to the black hole. Wouldn't the electron be converted into a photon by the means of...
Yeah, mathematically what your saying makes sense. However, I don't understand it conceptually. Entropy is supposed to mean disorder and chaos. The future of the universe going to end with a whimper, not a bang. Its going to be anything but chaotic with the temperature becoming absolute zero.
If the universe was hotter in the past, it was more chaotic and disordered with all the molecules and particles colliding with each other. How does this correspond to the second law of thermodynamics where things are supposed to get more chaotic as the time moves on, not backwards?
Neutrinos are thought to be particles with mass. So they aren't even supposed to be traveling at the speed of light to begin with, let alone travel faster. They would have to have some type of imaginary mass in order to do so. So what do you guys think will have to be modified in SR and GR if...
