Hmm. Now the qusetion is; Are you being polite now?

No, but it is somewhat unusual for someone your age not to know how to
dump google and get a decent newsreader and server. They're both free.

And Jim doesn't have an ilk; they prefer cooler climates.
Thompson is a famous Scottish name, so he does have an ilk. The Scottish
climate is indeed, at present, rather cooler than the Arizonan.
My ancestors were McTavish, came on the 1607 boat, but changed their
names quickly to Thompson to avoid trouble with the heathen Brits ;-)
They moved inland to what is now Culpeper, VA, then up into the North
Mountain (about 4500' altitude) area of what is now WV, a climate not
unlike that of Scotland.

Ah, the Culpepper clan, and a good quarterback they've brought forth. Not
nearly as good as the Brady clan, but he's a fine QB none-the-less.

How well did Arizona do this year (pick a sport)? Ok, your hockey teams

Ok, we have to do *something* up here this time of year. ...though it was

of days and my roof will be clear too!

I don't think this version of the experiment can be actually done. The
"measure the arrival times" part is not easy unless the shutter and the
detector are closer together than the length of the trip. If they aren't
there will be trouble making the shutter and the timer be in sync.
So, use a mirror to reflect the light back to it's source, then put the
transmitter and receiver side by side.
|
Yes this is very much the sort of thing that is done. You will have to
know exactly how far it is the mirror. Knowing the distance is easiest if
you range to it with a laser beam. This turns this version into something
more like the interferance version.

The trouble with that is that they aren't even getting into
thermodynamics yet (I can decode the latin roots of that I think -
temperature change?)
Crudely stated, the three laws of thermodynamics are:
1) You cannot win.
2) You cannot break even.
3) You always lose.
3) You cannot get out of the game. |

Not trusting _you_ and not trusting _anybody_ are two completely
different things, but it doesn't really seem like that's what this is
all about. Ever since you volunteered you age, it seems there's a bit
of "look at me, ain't I smart for 14?!" going on, no?

I don't really know that many 14 year olds, so maybe the question is
best left for you to answer. Do you know anyone else who's 14 who
understands quantum physics at your level of comprehension?

It's unusual for ANYONE to understand quantum physics.

Or even the Schrodinger & Dirac equations..

Maybe she's who she says she is (a kid who just turned 14) or maybe
it's a ossifer dangling hooks for a potential sting operation (if so,
usenet is probably not the best place to start such a career-- the old
farts here are far too sophisticated and vocal in "people" matters).
Or something else entirely.
The one gal in my EngSci class objected to the name "cardioid" for the
function of that name because it she felt the graph "didn't look like
a heart" (IOW the anatomical kind rather than the Feb. 14 kind). IIRC,
she was the daughter of two professors who had lived overseas for many
years, and thus probably more than a bit cut off from popular culture.

Who cares how old you or anybody else on this group is? I don't. But rest
assured: since you don't seem to have figured out yet that in general you
don't gain respect by bragging about your abilities you have proven to be
at least naive enough to pass for a normal, healthy 14-year-old.

No you don't. But she's definitely female.
If she's truly 14 the father needs to get off his football butt and
make sure his erudite daughter gets all the support and education she
will need.

Yes, including a thought about whether the problem with mathematics is

But fix it only if it's in her interest. Precocity should by no means be
repressed, it should be challenged, but, on the other hand, it should
not be *over*-stimulated. I know of a case where a young lad came to
mental harm that way.

Yes, over-fertilizing is as bad (or worse) than not fertilizing at
all, but a large pot is usually better than a small one.
