I know this is off topic, but I have a physics question. In the game of computer solitaire, does dragging a stack of cards require more energy than dragging one? At first glance this seems like a frivolous question, but it seems to me that amount of electrons emitted might be different. I realize there wouldn't be a huge difference. Thanks for considering this in advance.
Marvelous show! It answered my question about how collisions can occur in an ever faster expanding universe.

It is interesting that L. Riofrio at http://riofriospacetime.blogspot.com/ claims to prove that the speed of light is slowing down. (Her blog is listed in the left column of this blog as "A babe in the universe")

That must be a masterful poem because I didn't understand it.

Are you familiar with Joy Hakim? I saw a talk she gave that indicated that before she wrote "The Story of Science" series she was scientifically illiterate. She sort of "learned on the fly". I wonder if your own (I think admirable) experience might parallel hers.

When I was learning to solve a loop equation (electronics engineering) of a circuit, a lot of times we would end up with an integral on one side and a differential on the other. Solving such an equation isn't easy (at least for me). Fortunately we were taught Laplace transforms. We could then use plain algebra to solve, and then use the table to transform back to the original domain. The reason I mention this is that there is usually a diferent approach which may be easier (without being wrong). I have often learned concepts that were difficult to grasp by seeing two completely different approaches to the explanation. Hope something in my ramblings makes sense. May the force be against you! (Since it's dark energy).

Curious about the math. 6 cubed = 216 * 3000 = 648,000 Newtons. Correct? (648000 joules/meter)

Thanks, I see I do have some more reading to do.
Am I behind the times in understanding that elementary particles are either a wave (massless) or particle depending on the experiment? Of course even a wave may be thought of as having mass in that it has energy and therefore mass due to E=mc2. Do I have some catching up to do?
Nobody loves Hitchhikers Guide more than me. It is with great distress that I have to point out a critical error in the book. The answer is 36, not 42. If the computers had gotten that right, everything else would have worked out OK. (Example: Rush L would have come in contact with his anti-Rush mass and disappeared by now.)
Isn't capitalism the best system currently known only because it takes it longer in a given soceity to collapse?
1st scientist "What are you working on?" 2nd scientist "Nothing!" {A team of researchers from the University of Calgary and the Tokyo Institute of Technology proudly announced in February that they had successfully stored "nothing" inside a puff of gas and then had managed to retrieve that same "nothing." That "nothing" is called a "squeezed vacuum," and the physicists tell us that a light wave can be manipulated so that its phases are of uncertain amplitude, then the light itself removed so that only the "uncertainty" property of the wave remains.

Ever heard of an anti-neutrino? Kinda puts your time theory into a cocked hat.

PS: If the LHC at Cern does create a black hole which ends up eating the solar system, boy are you guys gonna be sorry you scoffed!

There's no such thing as "time" so how could there be a plausible theory? "Time" is only an abstract concept we have invented to pretend that we kind of understand some things. Actually, it was probably invented by lawyers.

Bravo to those conducting neuroscience experiments! As a sufferer of clinical depression for 56 years, 47 of which it went either undiagnosed or misdiagnosed (depending on which therapist was involved) I look forward to the day when a real cure is at hand. I do not believe I will live to see it, but research must continue. I still believe that our science in general is in it's infancy, contrary to what the producers of TV medical shows would have us believe. In several of Feynmans lectures, he always emphasized how much we still don't know, which convinced me he was one of the ones most knowledgeable. Just wanted to say Keep up the good work. Silly little thing: I am confused how a tumor be implanted in an embryo and have "no contact" with it.

I came across this comment and am rather belatedly metacommenting: ["We could make jokes about top and bottom here, but that would just be tasteless. Please resist the temptation yourselves and aspire to a higher brand of humor." Yeah, quark jokes just aren't a good flavor of humor. We need to bring them up to a higher level of taste; I'm not down with this mindless juvenility. You might think such remarks are charming, but honestly they're just strange.] (Posted by Chris, october 30, 2007) Yes puns are at the bottom of the humor scale, but Chris is on top of the quarkuation.(quark situation), pun-ditly speaking.

I don't suppose some crazy (say Kim Jong IL or Mahmūd Ahmadinejād) might get ahold of some russian SS-25 missles, and use the info in the above study to gauge maximun effectiveness of spread of nuclear contamination?

Thanks for the tribute to one of my "great three" who were an early inspiration in my life, (Aurther C Clark, Isaac Asimov, and Ray Bradbury)
It's a shame that they stopped reading. For absolute clarification about "outliers" read "The Black Swan" by Nassim Taleb, MBA, PHD. His tenant is that improbable events are not just likely they are inevitable. And a lot of further edification.

Can't resist posting this oldie but goodie: There was a young man who was bright Studied Einstein's work with a might Then went out one day In a relative way And returned on the previous night!
How foolish those Japanese were to think that human illness was caused by tiny malevolent creatures. Preposterous! Everyone know illness is a punishment for less than perfect behavior.

Does anyone know what Lee Smolin (co-founder of Perimeter Institute for theoretical physics) is up to now-a-days? I'd kind of like to get in touch with him. Am posting everywhere, so as to spread the question as wide as possible. Thanks.

Someone (everyone?) missed the question above about how can two somethongs be a fraction of any measuring unit apart. I.E. can they be 1/7" apart? I think this is just an abstract question, but it would be interesting to hear some learned folks explain it. Thanks.
