I am 16, and I started lifting about 2 months ago. Every 2 days I'll lift for about an hour and a half. I have started to wonder whether this is too much because for some reason the only muscle that seems to get bigger are my biceps, even though I do excersises for my other muscles for about the same amount of time. Is this over training or is there something else?

I am was taking a math test on linear equations (the basics) and did the whole test, but I went and did the reverse of the problem ( like if there is a graph and you had to find the points for a line on the graph, after I found the points I would make another graph and put the line according to the points I had gotten from the original problem) but the second line is not exactly where the original line was. I am finishing the test Monday. I currently have an 87 in math, and if I do good on that test I could have an A. I am open to all suggestions

The navy uses lasers to shoot down missles, what if we could use lasers to shoot down bullets. Does anybody else think this is a good idea. Like if someone could wear a belt of lasers, and a small computer could determine if the bullet was going to hit the person, or even determine where the bullet was going to hit. It would have to be a very fast computer though.

Would magnetic propulsion be physically possible on a scale large enough to power a craft?

Two days ago I woke up and I could barely move my knee. When I sit down for long periods of time and get up, it hurts a lot worse than if I keep moving. It is my left knee that's hurts, and if I touch the right side of it it hurts. This has happened to me one time before, but it just went away after a day. I would rate the pain as a 7 or 8 out of 10. Ibuprofen doesn't seem to do anything, and I am going to the doctor, but it is still in a week, so does anyone have any suggestions on how to fix it or know what it could be. O, and if it helps to know I am 15.

Today I just woke up, and Whenever I bend my knee I feel a pain that I would rate as an 8 or 9 out of 10. I took Ibprofin, but it didn't seem to do anything. Movement seems to make it a little better, but I can't always be moving. This has happened to me 2 other times, but today is definitely the worst. Does anyone know what this is, or have any suggestions on how to make it better?
