What is Optical Camouflage?
Optical camouflage is a kind of active camouflage.
This idea is very simple. If you project background image onto the masked object, you can observe the masked object just as if it were virtually transparent.
This shows the principle of the optical camouflage using X'tal Vision. You can select camouflaged object to cover with retroreflector. Moreover, to project a stereoscopic image, the observer looks at the masking object more transparent.
Optical camouflage can be applied for a real scene. In the case of a real scene, a photograph of the scene is taken from the operatorfs viewpoint, and this photograph is projected to exactly the same place as the original. Actually, applying HMP-based optical camouflage to a real scene requires image-based rendering techniques.

The drawback is that when you move to another angle, it fails.

Why don't they consider planets to be only those made of rock like Earth?

I know that another planet sharing Earth's orbit would eventually put both objects into unstable orbits, possibly in a matter of mere years.

But I'm interested in a specific scenario, if Venus were placed in Earth's exact orbit, on the opposite side of the sun, but moving at a higher velocity (in effect “catching up” to Earth) then;

A) At what distance would adverse effects (major and minor) be felt on the two planets?

B) What would these specific effects be?

C) At what stage would the Earth become really unliveable?

Thanks in advance.

Ok, it's been taught to us in basic Algebra that you do multiplication and division first, then addition and subtraction (always left to right). My question is how did mathematicians come to this conclusion? I mean, who's to say that the math we've been doing could have been slightly incorrect?

A basic problem that is used as an example: What is 2+3*4? The answer is 14, but many people may say it's 20. Well why are we multiplying first? Is it because multiplying produces more than addition?

I'm just curious, because if the order were switched the other way, we'd really have a lot of equations to adjust.

I read somewhere of an area in the USA that recently received freak reception of radio programmes that supposedly had been transmitted many years previously. Does anyone know if this actually occured, and if so, was there any explanation as to how this could happen?

Im pretty sure you've heard of Einstein's Theory of Relativity. Anyway, it says that the closer you get to the speed of light, the more times seems to slow down. In other words if you and your friend were 10 yrs old and your friend was sent to say planet x which is 20 light yrs away in a ship that travels at 99.9% of the speed of light. Now this trip takes 50 years when your friend arrives hes only 10 1/2 years old and ur 55 YEARS OLD!!!. Anyway thats how it works now my question are the following. What would happen if we traveled at the speed of light??????? WOULD TIME STOP??? What will happen if we could travel FASTER!! THEN THE SPEED OF LIGHT!!??? WILL WE BE ABLE TO TRAVEL INTO THE PAST?? TELL ME WHAT'S BEEN PROVEN AND IF YOU DON'T KNOW ANY OF THIS JUST GIVE ME YOUR OPINIONS WOULD LIKE TO KNOW. THANK YOU.

Introns are just spaces inbetween exons in DNA. They do not contain any information, and just seem to be there. What is the purpose? Also, is it true that eukaryotes have introns, prokaryotes do not?

My questions are simple ones

My radiometer spins clockwise with black side on the right vertical veins and I would like to know does any person here know for a fact that if the veins on Crookes radiometer were reversed with black side on the left vertical veins, then would it rotate counter clockwise?

Also has there been any tests conducted with the crooks radiometer to determine if it could function if with respect to a slight reconstruction it was placed between two low friction spindles which were inverted at 90 degrees of its current functional state thus the shaft would be mounted horizontal and the veins would rotate against gravitational forces?
