  1. Re:Those who would trade a bit of freedom... on Study: Limiting Bidding On Spectrum Could Cost Billions · · Score: 1

    Surely y'all aren't naive enough to believe that whomever acquires the spectrum *isn't* going to do the same. They still need to be competitive, which means they still need to make money, and so they're still going to charge rates that are within the ballpark of AT&T and Verizon.

    Have you heard of Ting mobile? I have a plan in Illinois with two smartphones on it. My last monthly bill, with voice, text, and data, totaled $34.97. I'm not a heavy data user (only 79 megabytes), but still. You think AT&T or Verizon can beat that? I don't.

  2. Re:Newton? on Physicists Attempting To Test 'Time Crystals' · · Score: 4, Informative

    From the article: "How can something move, and keep moving forever, without expending energy? It seemed an absurd idea — a major break from the accepted laws of physics. "

    This is a real groaner to a physicist. Is there any solid matter near you right now? Matter does seem to be real, doesn't it? In the classical regime, accelerating electrons radiate energy. According to Newton, matter should collapse into itself. The electrons should spiral in until they hit the nucleus.

    Electrons in atomic orbits move without losing energy. The orbits are stable. Negatively charged electrons are attracted to the positive nucleus, yet they don't combine. Matter does not collapse on itself. It's not Newton, it's quantum mechanics, in particular, Heisenberg's uncertainty principle. Heisenberg uncertainty explains the solidity of matter.

    What is different here is the size and mass scale has been upped by orders of magnitude from electron orbits in atoms and molecules in this supercooled atom trap. It remains to be seen if the experiment will produce results. The scientific jury is out.

    Seriously, any part of physics that isn't significantly affected by quantum effects yields much more accurate predictions, as does chemistry.

    Nonsense. You got that backwards. Ever heard of an atomic clock, the most accurate timepiece? It is quantum mechanical. Chemistry is quantum mechanics. How does chemistry work without atoms and electrons, which are quantum objects? I think you confuse Heisenberg uncertainty with measurement accuracy.

    The most accurate measured quantities are quantum mechanical, e.g. the spin-flip transition of the 1s ground state of hydrogen, "hyperfine" frequencies, or maser frequencies. You think you can specify ballistic results to a part in 10^12 or better? Using an atomic fountain, measurements accurate to a few parts in 10^15 have been performed. This extends the results of Norman Ramsey, who won the Nobel Prize for his research.

    Michelson Morley was a negative outcome, wasn't it? This is one of the classic modern physics experiments. In general, tests of Lorentz Invariance are experiments with a "negative outcome." Many have tried to find a violation of Lorentz' dictum, all have failed.

  8. the weak link(s) on Chinese Hack New York Times · · Score: 3, Insightful

    The article makes no mention of the operating system of the compromised computers. This would be like an article on safety faults in automobiles that did not mention the make and model. Can't we have better security reporting from the grey lady? There is mention of a "domain controller" that was compromised to obtain password hashes and that a rainbow table must have been used to crack passwords. Is there anyone who does not think that it was windows computers that were compromised? I can't help wondering if M$ and the NYT have some sort of agreement about how they report on computer security.

    That's bullshit, as demonstrated by ample evidence - there are precious few human societies in existence or in history that had not, at some point, engaged in warfare with other societies.

    Sorry, but your claim about warlike human societies is controversial, as has been amply documented by Ryan and Jetha in "Sex at Dawn." I don't have my copy at hand, but this ancient warlike humans meme is a myth they dissected and disposed of in the book. See Ch. 13, "The Never-Ending Battle over Prehistoric War." For one thing, the earth was sparsely populated in antiquity. Most human communities simply did not interact with humans from other communities. Hard to start a war without an enemy. A large part of the book ("The Way We Weren't") concerns itself with showing some accepted anthropological wisdom is just plain wrong.

    Hmm. With tongue planted in cheek, what did you use for the length of a day, which is slowly increasing, due to tidal acceleration? If I make the simplistic assumption of a linear increase of +1.70 ± 0.05 ms/cy over a time span of 2^64 seconds, the total increase in the length of a day is given by 0.0017*2^64/(100*365.2425*24*3600) 9937419 years (100*365.2425*24*3600 is the number of seconds in a century with accounting for leap years). This obviously cannot be the case. We have no idea what the date will be 2^64 seconds from now, never mind that no humans will be around to record it.

    I have PhD in physics and mathematics. In a utopian USA, the idea of educating more scientists and engineers might be workable. In the current political climate, are you kidding me? Science is a dirty word for half the politicians in Washington, DC. I'm all for better science education. I'm not so sure the majority of my fellow citizens want that, though.

    I am typing this in Shanghai. My company is a microcosm of what is wrong with the USA. We're selling high technology to a Chinese company, and we've been hiring high school grads in our US location to do work that previously required a college degree. I've been watching americans and europeans selling their souls to Chinese businessman in the hotel lobby for two months now. This is where the action is. The US is a fading light. China is a pollution-spewing industrial juggernaut.

    I had the same thought. More time outside the home also exposes the child to more dirt, more bacteria, and more of the tiny little worms out there. The beneficial effect of this exposure is known as the hygiene hypothesis. Kids who grow up on farms and poor people living off the land don't get asthma and a whole host of immune system disorders. There was a recent article by Jane Brody in the New York Times about the hygiene hypothesis.

    Basically, a little dirt is good for you.

    Perhaps most bad reviews come from picky eaters?

    Online reviews simply are not trustworthy. No review is, really. You can't tell me what I like, and vice versa. We can probably agree that rats should not be running around the restaurant. We cannot agree on the proper seasoning levels and the drinks. Who knows what happened to your dish before it came out of the kitchen? If you dine out, you regularly place blind trust in the servers and the cooks. Why then compound this by trusting some guy with a yelp! account, who could be a shill?
