You can use your Steam, and GoG games anywhere, they are not tied to one box. This was one of Steam's original touted features, no physical media required to play counterstrike anywhere. This is much more convenient than having to go to that shelf over there to pick something to play, it's just mouse clicks away.
Yes, I'm aware that a force is applied in the opposite direction, but that's not what I'm talking about.
You don't just hit the brick and transfer all your kinetic energy without feeling it.
Actually that's exactly the idea, you'll still feel it, but not as much as the brick will. When you're contacting the brick your charging a spring, so while there is a force pushing back on you, it's not doing work, it's having work done on it. Once you have given the spring lots of energy, you get out of the way so that it doesn't turn around and give that energy right back, in a painful way.
I just went back and read my earlier posts, I was using 'force' to mean 'force that transfers energy' a few times without realizing it, sorry for the confusion.
I think I was being quite unclear before, recoil and opposite reaction force are not the same thing. The opposite force (F=kx) it put in gradually, over a span of about 5ms*. As the force is applied, the brick, as a spring, is being compressed and is gaining spring energy. (In the form E=kx^2). Now once the spring is fully loaded, the hand is either a) removed in time, and avoids getting any recoil energy. As a result the brick breaks and you're happy. b) not removed in time, the brick gives you back lots of energy, your hand hurts, brick is unphased.
So are you saying it's impossible to break a brick with your hand? Or that's it's impossible to break a brick without breaking your hand?
The force is applied gradually, because with the right technique the brick will act as a spring that absorbs the energy from your hand. Once you've transferred lots of energy into the spring, all you have to do is get out of the way before the spring hits you back with most of the energy you just gave it. Leaving the brick broken, and your hand not.
No, of course getting out in time doesn't break the brick, the force has already been applied. As long as you get your hand out of the way before the full force recoils, then the brick will break because it will contain a sound wave with too much energy to cope with.
Stop thinking about it as a rigid board, but as a spring that accepts force and recoils gradually. If your hand slows down during the impact, then the spring will just bounce back and give you a really nasty punch in the hand. This is what you are avoiding when you move out of the way. Since all the force just went back into your hand, the brick will survive.
Yes, there is a force felt as soon as contact is made, but it is not equal to the force of his hand because the brick has give.
The brick is a high-tension spring. Imagine karate guy is hitting a soft spring instead of a rigid object, then you'll probably understand what he meant when he talked about getting out of the way in time.
No, you're the one who has mixed up mechanical and em waves. When he strikes the block he initiates a slow moving pressure (sound) wave, that's why he has time to move out of the way before the force hits him on the rebound.
If physics does not work this way, then please explain why sound propogate through solid (and non-solid) objects at roughly 1 millionith the speed of light?
No, they were rich kids. They both attended a private high school that cost $35k a year room and board. These kids didn't die because their parents drove German cars, they didn't die at all. One kid killed an innocent man because he was a moron rich kid.
Judging by the response to the C&D, he was abiding by Fedex's policies.
Think about it. 2,000 twenty somethings each order enough free boxes to outfit a one bedroom or a small studio in bed frame, chairs and desks. How much will all those boxes cost in raw materials alone???
Nothing if Fedex has any smarts at all, because they just shouldn't send them out.

Closer still, it's 12 nautical miles, approximately 14 miles.

The CRTC will follow by going in the opposide direction, as today they granted UBBell hell.
toast, still not free
Baseball games have breaks every 7 seconds where TV co.'s can put in ads, soccer has only 1 break per game.

Here's a link I found that explains the springy brick feature.

The link touches on some of this, might want to check it out.

WRONG
The board recoils with most of the energy you just gave it when you hit it.
News flash, forces transfer energy.

Plasmas are electron gases. From the first line of the wiki link, "plasma is an ionized gas".

Nope, it's 19.
Nice pun..
Reference, or makin' shit up?

I think you missed the first stage in responding to an argument, reading the original argument.
Making someone press the delete button is not a physical threat.

Don't need to wish me luck, it's not my problem.
Awwwwwwww poor multinational corporation!
a) Read the response to the c & d. He did not violate any agreements. http://cyberlaw.stanford.edu/archives/CIS%20letter .pdf
b) No one has sued anyone here, try RTFA.

I think most people (guys, slashdot readers) might learn about cunnilingus by licking a girl's vagina. I doubt it's just me.
