Where direct current?

In one article on Habre explains how to get 7V from the power supply. Sorry for the stupid question, but I can not understand how it is a steady current when connected to +12V and +5V. And where a minus? Can just give a link to me to read.

What opaque film/plastic is transparent in the near IR range?

Hi all. Comrades, in great need of advice/tip professionals. Problem: need to find a material that will not be transparent in the visible light range and thus will not be a barrier to infrared radiation of the middle range. Example: the eyes see black, opaque film/plastic. And in the image with night surveillance camera - y...

Simulation of motion of a body in orbit?

Apparently zamylilsya eyes. Can't find/understand where the mistake was. I was trying to make: A simple simulation of the motion of a body in orbit around the source of gravity. For this randomly exposed body, and it is calculated: the vector pointing to the center of gravity source => vector of gravity the tangent to t...

Why Geymdevu to know the real world physics, if you can't do in games?

Correct if wrong, work absolutely in other sphere, about the game dev know very little. However, very interesting :) It is obvious that real world physics cannot be used in games. Then why know it the developer? What part of physics can help to develop the game? Interested only in the research plan.

Why multimeter readings when measuring resistance constantly jump and reset and can not give accurate result?

Bought a elitech 100 mm multimeter with probes included. When measuring the resistance value is constantly jumping and reset, can not give the final result. Continuity test works through time. I think it's the probes that came in the kit, but this is just my guess. The problem is whether to buy new probes. If so what? It is...

Why Jupiter has a Hexagon at the North pole, like Saturn?

Why Jupiter can not meet this phenomenon? Because Saturn and Jupiter are similar. Maybe there is some influence of satellites, or a higher speed of rotation of Jupiter, unlike Saturn. Even with the Land you can meet a kaki analogy(https://en.wikipedia.org/wiki/Jet_stream), but with Jupiter or, for example, with Neptune ther...

C++ OpenGL implementation of physics where to start?

My knowledge in this area is extremely small, and yet the only conflict to which I thought, this collision of balls, but somehow not interested, I want to do on OpenGL some mini games, simulation, etc., but can't figure out how to work with physics ( I was on collision ), and I can't even imagine how to make it, and even so...

The laying of two coaxial cable in parallel possible?

There is a repair in the apartment, the apartment comes cable satellite TV and cable KTV, initially they were not met along the way, after repair paved them in parallel (15 meters go hand in hand) will they degrade the interference signal each other? If you can detail and you can link to. I would not want to degrade the sig...
