Physics and tricks

As far as I know Richard, physics doesn't need the tachion to be able to express itself in quantum mechanics, it manages that quite easily on its own, correct me if I'm wrong young man

I know that QM has a number of tricks like expressing certain things as a particle. The only example I am certain of is that of the phonon, which is a sound particle. I am aware that the time, which is what a tachion isI seem to remember, is one of the issues that QM has when relating itself to relativity. This is because relativity treats time as a dimension, wheras QM treats is as a perameter. Neither QM, Relativity (special or otherwise), super-string theory nor any other model that scientists use to describe the universe can do it completely, so some of the these fudges and tricks are required to make it all work nicely.

To be fair it is not just physics that requires these tricks, it is chemistry too, but as Feynman said, "We can divide up mother nature, but she doesn't believe a word of it." [sic]

ummm...guys, do I have to break out that pocket protector again? I'd much rather not, as I'm having fun looking for nipple in Tomb Raider... hey, how about that lack of angular momentum in a paintball? And how come I never saw the Animal Girrlls in HB? Some of their pics look as though they were taken in Long Beach.

I was noticing that some of the chrono's were reading a bit higher than others in HB and I wonder if the fact that some of them were being pointed into a metal trash can had anything to do with the discrepancy...I mean, sending out a radar source to bounce around a metal can and expect the electronics to reliably pick the tiny paintball out of the resulting clutter? I think I liked the "Shoot into a traffic cone" idea. The plastic is more transparent to the radio waves (and tough too) and you can place a bucket under the tip of the cone to catch all the goo, just bend the tip down so a paintball can't fly out the opening.

Also, if we start talking quantum physics an Brownian Motion, then isn't there only a percentage probability that we'll occupy a particular physical location? If so, then can I utilize this "percentage" value to "Ghost Walk" on the opposition and to make sure that the probability that I'm in the way of a particular paintball is essentially zero? Hmmm... maybe I've read "A Wrinkle in Time" once too often... of course with my luck, if I randomize my location, more often than not, I'll end up out in the open since there's more open space than behind-bunker space. Oh well, time to go back to staring at Laura Croft... oh, and some people across the pond use the spelling "Tachyon" but then again, some don't...

PS Hey, no lie, I was talking to the Materials Engineer/laison of JPL, Scott, on Monday He's pretty upbeat about the Mars thing coming up.

Nope, you have (I assume) too much mass for that. The problem (or solution, since I don't like the idea of defracting every time I go through a doorway...) is that there is just too much of just about anyhting bigger than an alpha partical, quantum gravity kicks in, and your wavefunction becomes so close to discrete that it makes no odds.

Enjoy looking at Lara, I'm going to do somehting more useful now

There is no definitive explanation of either QM or Relativity as you say; high end physics is all about the compromise of thoeries with observations and in the end, all we have to do is to use our branes !!!
Hee hee, get it ?

Just re-route it through the deflector aray. There ya' go. Works every time.

It's all in our head

As far as observations...I guess that's why most of the guys who stop talking when the overhead shell's pitch gets higher, start talking when the pitch starts dropping, yet they don't even know what "relativity" is or who Doppler was. Reality is there, even if the theories can't always explain it (key in the X-files music)...because "The Truth is Out There"...sorry, couldn't help myself.... I'll go sit in a corner now, 'cause I can't even remember what Green's theorem was, much less how to use a delta function (area = 1).

Flames getting higher.....adding petrol to the mixture

Seems to me the very first original post is right?

If the ball is leaving the barrel at 300 per sec from every marker on the field, (due to the chrono limit of the day) then in theory everyone would have the same range and ball flight characteristics.....

 

[JoseDominguez]

Yup, but every little natural variation will affect flight. humidity, wind, barrel condition, angle of flight, "hop up", etc.. etc..etc ..so "putting an end to the discussion" is never, ever going to happen, but we keep trying. Trying to convince everyone that barrel length doesn't affect accuracy is like trying to convince year nine kids that the primary colours are red, green and blue....... it's like banging your head on a brick wall. And if you think that's bad, try teaching Darwinian Evolution to the daughter of a creationist minister.

At last someone has come up a conclusion Robbo is spot on.
My studying for my masters degree has tought me that it is down to prediction as there is no firm explanation.
the acuracy thing is fine but it all makes the asumption that air is traveling square to the ball for it's duration. This is simple not the case most markers the air flow is turned thro' 90 deg several times so each marker would have it very own effect on the ball.

well I asked my physics teacher bout this sorta stuff, and he said "shut up Paul, and for Christ's sake, sit down." so there ya go.
