Is it possible for airplane radars to scan minefields? If we were to take an airplane radar out of the plane and brought it back to land in a vicinity of a minefield, would it scan the mines that are in the minefield? Would it be able to scan because mines are not on the surface, but buried...

I have asked that since I wanted to know if it was possible to create a suit using magnetism that allow people to work in areas contaminated by radiation, like after an explosion of the nuclear bomb. How strong would the magnetic field need to be for a human to enter a contaminated site, like...

People, I am not a physicist, I know physics in theory. I deal with tactics, not physics. This forum is nice and there are a lot of smart people, so I wanted to introduce my ideas to you for you to evaluate from physics' perspective. I am interested in something else: can magnets be used to...

I have found what I needed. Thank you anyway.

First of all, when I research something I go to wikipedia first and read. If there I can't find what I'm interested in, then i go to forums. On wikipedia there is only a superficial article about thermal vision, nothing in detail.

Okay, I just wanted to check if my idea was possible.

I am interested to know how does thermal night vision works. Can anyone explain that to me, I would be thankful. I want to see the physics perspective on this.

I know that the Americans managed to develop helmets that deflect bullets. Weren't the Germans the first to develop those helmets in WW2? The Americans probably developed it further. I am not that familiar with that. I know that, in older versions, if the bullet hits the helmet directly it will...

I have yet to really start studying the details. But yes I am familiar with reactive armor. I have not yet looked at it from physics perspective though, I was more interested in tactics, but I have a lot of ideas. So, now I am checking if any of those ideas could work IRL.

I am interested in military stuff. I have studied helmets and if it is possible to add some form of magnetic current to repel bullets. Of course, copper is essential in the jacket of a bullet, so I am interested to see how strong the magnet has to be. I have read something about magnetism, but I...

I have read that, while copper is not magnetic per se, if we have a strong enough magnet, it can interact with copper. This ties in with the fact that all matter can be magnetic if you have a strong enough magnetic field. But I am interested, how strong must the magnet be to interact with such...

Hi guys! I need help about explanation how to work turbojet. I have read about turbojet on Wikipedia and I know how to work turbojet in base.But some things are unclear to me. I would be thankful if someone explanation how to calculate elements about turbojet. Thanks!
