Bob, then you are an "old fart" like myself. :-)

Actually, you're not quite that old, since the first edition of
Halliday and Resnick was copyrighted in 1970, while Sears and Zemansky
dates back to 1949. Still, both are excellent introductions to physics
for the serious student.

Seems to me I had Sear and Zemansky for thermo. As for H & R, the
copyright date in my volumes is 1960 -- making me the older fart, maybe.

My H&R volumes are worn out partly because I used to keep them
by my bed, along with the Statistical Abstract of the United States
and Goodman & Gilman's Pharmacological Basis of Therapeutics,
any of which I could study for many hours at a time -- purely for
a warped sort of late-night obsessive 'fun.'

These days, I also enjoy watching Goodstein's 'Mechanical Universe'
series, over and over again. As Feynman once remarked, there are
always new insights to be got from the basics.


On a plus note, you've inspired me to visit Radio Shack and pick up one
of those laser pointers to play with. My only laser currently is a
surplus assembly from an early supermarket scanner that will eventually
either electrocute me or zap out my eyeballs! (In my case, having
cataract lens replacements in both eyes, I need to be a little
cautious. Too much neutron flux in my earlier years...I guess.)

Cataracts, huh. Jeez, maybe you are the older fart.

Great idea, to fool with the cheap equiment. E.g., I have a tiny
CCD (~3 mm on an edge) from a Logitech WebCam (or whatever it's
called) that I illuminated with laser light coming through a pinhole in a piece
of brass shim stock. You can see it at http://www.flashevap.com/LI.jpg.
I suspect that what looks like interference in the image is actually
more like a moire pattern on the CCD elements.

Just to run on a moment longer about science on the cheap, I
recently got some sea shells at the beach in Delaware and
mixed them with charcoal from my woodstove, then fused it
all up with the arc from my welder and made calcium carbide,
which can be fun to play with. Aluminum sulfide has
interesting properties, too, and you can make it the same
way. In fact, while I'm on a cheap-science jag, check out the
iron ring that I extracted from the clay in my yard here in Maryland,
with the arc welder. Buy one of those, if you want to have
some high-energy fun.

Where were you exposed to neutrons? I have some questions
about that sort of thing.

Sorcerer, actually I should have steered him to a textbook explaing
Young's Experiment rather than some simplist web crap.

A little late, but here are two:

"Fundamentals of Physics", Halliday & Resnick. Page 784.

Good ol' Halliday & Resnick. I've had both volumes for over
40 years now. I consult them often -- so often the cover has
fallen off Volume II, the one with page 784. Wonderful set
of books.
