There is a problem in my technological concept that does not allow the normal development of the plot of the book. It takes place on an ocean planet where being above sea level is absolutely dangerous with the level of technology that exists there. So all combat operations there take place...

If trees are cut and then burned they have not reduced the CO2 in the atmosphere at all. And if they are left in the forest and then rot 90% of their mass also go back into the atmosphere. Here in Germany we have many old salt mines. I wonder if it would be a good idea to cut trees and store...

I thought of this problem: The roads AB and CD have block E in common. There are 6 blocks in road AB and 13 blocks in road CD. Someone has planted a mine in some of the blocks. He gives us this information: 1. There's only one mine in road AB in one of its blocks. 2. There's only one mine...

Hi, I am a Industrial Design student working on my senior Thesis. Since antipersonal landmine cleareance is a very dangerous process; I am working on a remote controlled vehicle concept that will be able to do a controlled detonation. That way the human won't have to manually disarm the landmine...

Hello everyone, I was wondering if anyone had any advice. I have the opportunity to study at either Colorado School of Mines for MECH Eng. or at CU Boulder for Aerospace Eng. I wish to work in engine design at NASA or Space X or really anywhere eventually. So I was wondering if anyone had any...

As we have so many oil mines around the world, how large are these holes left behind, and what is put in place of the oil that is taken out. wouldn't the pressure be different? and what would happen if a oil cavern collapsed?

I'm heading out to CSM for the fall semester, and I'm wondering if anyone knows anything about the school. I've done some research and I know the "party line", but I'd really like to hear what people on PF think about the school, or it's reputation. I'm planning to go into either Chemical or...

I'm planning to transfer to a university soon, and as of now I'm pretty much dead set on studying at Colorado School of Mines. The reason why I'm asking about South Dakota School of Mines is because the cost of attendance is very, very, attractive: $14K a year for out of state students. The...

Hi guys, i am about to graduate from my mechanical engineering degree, i am thinking of going into the mining industries, becoming an on-site engineer. People have been telling me that it's a job that pays VERY WELL, but the downfall is that you will have to be on the site for 6 months every...

Sir, How does the pressure vary as we go deep into the mines and as move up into the atmosphere? I think as we move up into the atmosphere the pressure decreases. I am not sure.
