really makes you think

Approaching the speed of sound in an aircraft is relatively difficult, because the closer you get to Mach 1, the denser the pressure is around you (sound accumulates causing vibrations).

Is there a similar effect as you approach the speed of light? Does the Doppler Effect apply for light as it does with sound? Will light accumulate around your aircraft causing heat? Speaking strictly hypothetical.

Is the sum between an irrational and a rational always irrational? How can I prove this?

Hey /sci/,

School student here in final year of high school. For a long time I've had problems remembering formulas, mathematical equations, etc and it has inflicted negative results on my marks for particularly Mathematics and Physics. I want to know if there is anything I could do to improve my retention of such information. When it comes to theory for subjects such as Chemistry, Biology and even Physics, I can manage pretty well. I would like similar for numerical information.

Please help /sci/, any tips or pointers that helped you out in high school.

Are you trolling to make that other guy look bad or did you type that post seriously, you mong?
