and here was me thinking "plasmas" implied those things

Useless....... unless of course you reach the critical temperature in hydrogen gas where fusion becomes self-sustaining. This is how fusion power plants will work in a few decades.

Can't have any connections with brain cells. In general, nerve cells do not regenerate. Some regeneration occurs, but it is typically negligible. Marijuana kills brain cells. This is an undisputable fact. Whether it kills more brain cells than alcohol or tobacco is open to debate, but it's not good for you. It has also been linked to impairment of short term memory.

Why is a photon its own anti-particle if its spin quantum number is 1, shouldn't there be an anti-photon with spin -1... i know all the other quantum numbers are zero.

The difference here: it's over. it was a walk in the park.

You need them if you're lazy and/or don't understand it. Personally I think taking calc 1 again is a waste of my time, so there's no reason not to do a hour long test in 5 minutes on my calc.

You can't possibly compare the military campaign in Iraq to the one in Vietnam.

Unlikely that this won't bother those pesky ethicists, i.e. extremists who believe even if a baby has severe birth defects and won't survive more than a couple days after birth should still be carried full term.

This is the one and only victory Iraq can claim since the war started. NAJAF, Iraq (Reuters) -- U.S. Marines may consider themselves an elite fighting force, but they were no match for an Iraqi soccer side who thrashed them 7-0 in the southern town of Najaf. The Najaf Poets devastated a side drawn from 1st Battalion, 7th Marines, their yellow jerseys flashing past Americans who took to the field in combat boots and camouflaged trousers. Marines said about 600 locals thronged an athletics ground in the town to watch the match, organized by U.S. officers hoping to establish friendly relations with residents. The Marines, who took control of the town from the U.S. Army last week, said their underdog status even won them some sympathy from the home crowd. "They were cheering for the Iraqi side, but they were also rooting for us, because we were getting beaten pretty bad," Major Mark DeVito told Reuters after the match.

So can IE with a simple add-on program.

E = mc2 is and always has been true. No. This is not true. It has never been true, and it never will be true. No body is completely at rest.

Where's the evidence for it? I've seen evidence that the speed of light has not been constant over large timescales. It's also a well known fact that light travels slower through mediums (like air or water), but I haven't read this book... so perhaps you can summarize what evidence the author presented.

Well first of all I'd be highly skeptical of some no-name person who writes a book (vs. a research paper, which would be required to refute the experimental evidence supporting einstein). Books do NOT prove anything wrong. Technical research papers presented to the scientific community (not the general public) do that.

Computers are overtaking TV for occupying kids time... at least they're interacting.

Beats Church rule like Reverend Ashcroft is trying to establish...

The standard model has its problems... But if you had to classify a photon particle (think wave-particle duality, so it's certainly not a very good way of classifying it), it's more like a lepton than a meson or baryon.

what about electroweak unification?

No one thinks all drugs should be illegal. Caffeine, aspirin, etc... are all drugs people take all the time. Where do you draw the line? For example, a few dozen milligrams of DXM is the most popular cough supressant, but a few hundred milligrams is a powerful dissociative drug that produces intoxication and closed-eye hallucinations. 1500 milligrams (2 bottles) will put you at the level of surgical anaesthesia, and much above that will kill you. Also, anything above a few hundred mg will kill billions of brain cells. Yet this is an over-the-counter drug, should it be illegal? It's all about proper use.

You don't, only moderators get custom status.

Photons do interact in the form of energy transfer... certainly you've heard of photons breaking chemical bonds.

... you name your cat Schrödinger.

??????????? a photon is its own anti-particle.

Who would really want to go to Toronto in the first place??? There's no SARS epidemic there, they just finally found something to blame the lack of visitors on!

Not by much... that's why college students can kill millions of brain cells every weekend and still do well in classes

Only massless leptons travel at c. A particles classification as a lepton has little to do with its velocity. If an electron was travelling at c, it would have infinite mass, since its rest mass is non-zero, unlike another lepton-- the photon, which has zero rest mass and travels at c.
