A little qustion about superhero/manga hero science

[Grimlock]

I was just watching Bleach where Ichigo released his bankai/superpower that allowed him to move at incredible speed. This resulted in that he to his opponent looked like he was several places at once and i remembered that Bleach wasn,´t the only Manga where the hero was capable of that.

Now i know that no human is able to obtain that sort speed, but for the sake of argument lets say they where.
Could you (without completely raping the laws of Physics) actually appear through speed alone, as if your at several places at once? I could imagine it would be like slowing down for a brief millisecond enough for your opponents brain to register your position then speed up again and doing the same thing over and over again.

Oh that illusion is easy to make.

Step 1: pencil.
Step 2: Put it between the thumb and index finger.
Step 3: Wave it fast.

Doing that on human size probably wouldn't be possible without the target being shaken into goo.

Anyways, in theory I guess it is possible. Sorta.
Impossible in practice though.

It reminds me of an electric fan or the propeller of an airplain, once they reach a certain speed, it looks like the propeller is rotating in the opposite direction.

So you noticed that too(though with me it was the wheel on a lego toy) i thought of asking just what in the world was going on if its the mind that,´s playing tricks on you or just what it is.

Maybe our eye is just not fast enough to follow the speed of the fan.

maybe the animator got lazy?

http://www.100fps.com/how_many_frames_can_humans_see.htm <-- grim, this answers our problem. ^^

Now take your hand and move it slowly in front of your face. Then move it faster until it's blurry. How many frames per second do you see? It must be little, because you see only a blurred hand without being able to distinguish every change per millisecond, but it must be many, because you see a fluid motion without any interruption or jump. So this is the eye's trick in both examples: Blurring simulates fluidity, sharpness simulates stuttering. (It's similar to "rotation simulates gravity".)

Maybe if you had a lot of fast twitch muscles you might be able to move that fast. I know that snapping shrimp can snap their claws so fast it produces a fish killing shock wave and happens to fast that human eyes can't even see it happen. Mongooses can also dodge cobra strikes so quick that only high speed cameras can pick up their movement, so I suppose that's kinda close to what you're talking about. At the very least in reminds me of the whole DBZ teleport thing. But I don't think it's possible for a vertebrate (or any other animal) to move that fast and simultaneously switch directions multiple times without pulling a joint out of its sockets to do the whole appear-to-be-in-several-places-at-once-thing.


Btw GITS:SAC pwns Bleach!
