Nothing can travel faster than the speed of light? What about when i'm driving my car at 30 MPH and I put my headlights on? Wouldn't the light come out at the speed of light plus 30 MPH? THAT'S FASTER THAN LIGHT BITCH.

/sci/, how come I can't retain any information? Every time I study (which is hell already because I postpone and get distracted and shit) I forget the material learned within a few minutes. And retain maybe 10% after a day. Currently I'm in engineering school and I'm failing because I simply can't remember things long enough for the test. This applies to everything from mathematics( I can't grip concepts for shit) to downright simple shit like bussines. >inb4 not learning enough

Neurophysiology

Hey sci How does an action potential propogate along a neurone? If we assume that sodium ions diffuse passively along the axon, it would cause hyperpolarisation further down the axon (according to the Goldman-Hodgkin-Katz equation and cable theory). From this you could conclude that the initial assumption that sodium diffuses along the axon is wrong. Does anyone know the actual mechanism?

If I shine a flashlight into a handheld mirror, obviously the light bouncing off the mirror is moving at the speed of light. Now if I give the mirror a quick snap of the wrist, I've just increased its speed beyond that of light to Light + the Speed of Wrist Snap. And I didn't achieve infinite mass or anything. Conclusion: faster than light travel is possible. QED

If you where to go in an elevator step on a scale and go down you would "weight less" Because of the normal force being reduced. Is this because since force is mass times acceleration and when you go down you accelerate downward therefor cancelling out the normal force? Also what if you stopped accelerating and went at a negative velocity (Downward) would the normal force already be cancelled out from before and not come back?Also what if you where to move faster than gravity (-9.81) would you experience a "negative normal force" or like complete cancellation of normal force and a new force pushing you upward? Am I at least close?

Would something as this be treatable? Will the doctors have to involve surgery to align all the bones into correct position after which they fix it, or is it done in some other manner?

/v/irgin here, this may be strange and I'm not even sure it's topical for the board but I have a question. I have a cousin who has just graduated from college and has become a physicist. He's fucking awesome so I want to get him a Christmas gift but I need opinions on what a physicist would like. Any ideas?

Dear /sci/, Is it possible to launch a rocket from a balloon? The launch components will get very cold, is there a way to keep the rocket in good condition for ignition and blastoff? https://www.youtube.com/watch?v=fEJGI3NjJso

If I have two integers, say x and y, one of which doesn't divide the other, can I find two other integers, say a,b, such that 1 = ax + by? I add the condition x doesn't divide y because if it does, then you end up with just the multiples of x, and so you may not have integer solutions. (i.e. x = 6, y = 12, then any combination is a multiple of 6.. clearly there is no integer solution a * 6 + b * 12 = 1). The reason I ask is that I believe from trial and error that if you have two integers where x doesn't divide y, and they are two known elements of an ideal of the integers, that the ideal ends up containing all integers (if I can show 1 is in the ideal, then 1 + n * 1 can be solved for any integer). The reason I'm even wondering this in the first place is that I was curious if you can generate an ideal in the integers using more than one number (rather than say, the multiples of a single number). However, exploring it made me think you just end up with all the integers and not a proper ideal. Please help, I've been stuck on this for hours.
