In road signals, red on the top,  green at bottom but in railways is it reverse. Why?

Probably because all train engineers are dislexic.

That would be "counter-clockwise" not "anti-clockwise". Motor sports in Australia are generally run with the drivers turning right on ovals, so that's probably what you saw, unless you are referring to a road course.

Just a quirk of history.  As to safety, there's really no difference.  In places where folks drive on "the other side," the driver is also "on the other side."  This means that visibility remains the same.

Basically as everyone suggests it is to do with magnetism. when electrical items are operated they generate electrical fields that in turn have magnetic fields. the same can be said for fixed magnets. These fields bend the "beams" within the CRT and illuminate the wrong phosphors. such a phenomenon Displays as a purple pink (usually) or red patch on the screen. The degauss coil you operate when you push the button generates a small localized magnetic field of its own which slowly dissipates as electrons through the components within the circuit thus restoring the CRT's normal magnetic field, resulting in the proper phosphors within the CRT being excited rectifying colour problems on the display

It's still considered a "right-of-way" violation. The driver with the legal "right-of-way" is the one with the green light, whether he's an idiot or not. Up here in New England (and I'm sure everywhere else), we have a lot of drivers that go for miles with their blinker on. I wait until they have actually started making the turn to go, because once they start turning, they lose the "right-of-way" on the street they were on.

It stems from our anti-British values back in the days of the revolution.  It is the same reason why our horse races, and car races are ran counter clockwise on the track.  The British ran their horse races clockwise and we were so anti-British back in the day that we did it the opposite.  It snowballed from there.......

You are seeing the effect of pressure on the rods of your eye, which are fooled into thinking they see light. It should appear on the opposite side from which you press. It's called "phosphene".

that ur not using signals(blinkers) to change the lanes

If you are holding the cartridge with the label facing you, the colors go from left to right: yellow, red, blue.  Do not go by the sticker that is on the cartridge itself as HP purposely puts the colors in the wrong order to mess people up.\n\nHere are some instructions:\nhttp://www.pacificink.com/downloads/FHP-78.pdf

Most of the world. Left hand side driving is the exception, and tends to be on islands. UK, Japan, and the like. \n\nNotably, Sweden changed from the left hand side to the right on a day known as Dagen H.\n\nThe second wikipedia link has a map showing right-hand driving countrys in red, and left hand side in blue. You'll  note that most of the world is red.

That's the traffic light on the information superhighway... when it's red, all the information has to stop, it can only go on green.  \n\nThis method is commonly used to prevent data packet collisions and thus minimize loss of data and resent packets.  Nothing clogs up a system more than having to resend a bunch of packets... it can be a real mess.  \n\nEvery once in a while, you will get some rouge program (probably from CANADA) that does not adhere to the red / green convention, and just runs amok.  If this is the case, you have to call the information superhighway patrol (ISHP) and get them to write that guy a ticket.  \n\nCheers!

Because the up/down motion is independent of the side-side motion. The stone is already going at whatever speed the car is and that doesn't change. The only thing that changes is the up/down part of the motion. For someone outside the car, the stone looks like it goes along a parabolic arc, not just up and down.\n\nThis is related to the relativity of motion. If you are moving uniformly, it is impossible to tell whether you are moving or not unless you look outside the car.

I don't know but that pisses me off too. I guess it makes me uncomfortable when the person in front of me stares. My logical guess would be that the train goes in different directions during different parts of the day. When the train is going one direction, they have to bring it back at one point. So they make the seats where whatever direction it's going in, you can see it at different times.

It doesnt reverse. You see yourself how others see you. It's not like the light waves are switching sides. . . it's the fact that they're staying on their own side that makes it look like they switched!!

The 'Doppler Shift' indicates the color or wavelength of light.  Light traveling toward you would be more in the red end of the spectrum, while light traveling away would be more in the blue end.
