  2. share price argument is not correct on Has Google Lost Its Mojo? · · Score: 1

    I am not a economist, but it seems to me that the share price a company that has a large price/earning ratio is largely based on expected increased future earnings. This acts like a multiplier. Its price will fluctuate more than a company with a lower p/e.
    So it seems to me only natural that google's share will fall more than average when prospects are bad.

  3. Re:An interface called "Shake"? on Open Source Linux Phone Goes On Sale · · Score: 1

    Besides, it is virtually impossible to know your position however precise your accelerometer is. Even if you know (or define) your starting position you have to take a double integral of your acceleration signal over time. This means that any errors (even a perfect accelerometer will have thermal noise) will accumulate pretty fast. Could could be standing still and your accelerometer will have no clue whether its moving or not!

  4. Re:why the moon? on Lunar Lens Takes A Step Forward · · Score: 2, Informative

    The telescope works with gravity, there's no gravity in space. More precisely, there is, but you are continuously falling so you don't feel it. However, you could use a telescope that slowly falls towards the sun and use the solar wind to stop it from falling and also create a weak gravity force. Could be enough to build your telescope in space.

  5. only looking up? on Lunar Lens Takes A Step Forward · · Score: 1

    What about the orientation of this telescope? I guess that if it works with gravity, it can only look up and cannot be rotated. Luckily the moon rotates one full circle per 28 days, but still you miss one dimension to cover the sky. You could use another normal mirror to point it wherever you like (like shown here) but then you will need an enormous normal mirror, let alone that you might nor be able to manufacture it with the same smoothness a liquid mirror has.

  6. Similar things are happening in Greece on Comcast Accused of Blocking VoIP · · Score: 1

    This is not new to greek ADSL users...
    The company OTE is Greece's main telephony and adsl provider. However, the adsl lines (which are by the way extremely expensive) are crippled and it is impossible for many subscribers to use any voip service (skype, voipbuster etc.). This is done as follows:
    The advertised bandwidth is provided on a packet rate basis! (of course not officially, but very easy to test) assuming a maximum MTU of 1500, which of course means that any application that uses small packets (see voip etc.) is doomed not to work as the bandwidth plummets. This is blamed by OTE to network congestion, not able to guarantee bandwidth and other bla blas that you have signed for when getting the adsl line. It just happens that it is very convenient for the major telephony provider in Greece! It is ridiculous but true.
    For anybody interested there is a very long thread where we, the victims, discuss our frustration (in greek)

    My knowledge of capitalism is limited and I have a question:

    Their current owners are also investors, with their interests. I don't see how going public, i.e., more (in number) investors, will change that, could anyone clarify this for me?

  9. Re:Methinks we aren't getting the whole scoop here on Sony Projector Gets Bright Images From Black Screen · · Score: 1

    Indeed "white color" consists of photons of various "colors". The idea here is that a color like, say yellow, is absorbed by the screen. Normally the green ambient photon which would excite your red and green receptors in your eye will be absorbed. However, the yellow pixel formed by the projector will consist of red and green photons which are not absorbed by the screen. So you see the yellow of the projector and not the yellow of the ambient light. The same holds for a cyan ambient photon versus a green-blue (=cyan) pixel of the projector. Of course you're not getting all the ambient light out with this system but the narrower the pass bands the better the effect. I think the system is ingenius.

  10. No limits on Moore's Law Limits Pushed Back Again · · Score: 1

  11. Re:Artificial Eyes? on Philips Develops Fluid Lenses · · Score: 1

    I am not an expert in optics, but from what I remember from school, just changing the focal point does not give you zoom capabilities. This just allows you to change your focus. However, this might be interesting for older people who have use dual focus glasses. The problem they have is actually the fact that their natural lens has lost its flexibility and they cannot change their focus anymore.

  12. Re:Extra Transistors on Current Processors Tested With Linux · · Score: 2, Insightful

    Adding a number stages does not necesarily mean you are adding as much hardware (transistors). You can simply divide a stage into two by adding a few latches and nothing more. This can be done to increase the clock frequency.

    Example: you have a unit (say, multiplier) that has three stages, each of which can complete within 1 nsec. This means your clock can run at 1GHz (1/nsec). If you divide each of these stages in two then each of these new stages will complete in .5nsec which means you can run your clock at 2GHz. No extra functionality and no extra transistors, not counting just a few latches.

  13. How is empty space defined? on The Amazing Properties of Aerogel · · Score: 1
    Could someone explain to me what they mean by empty space? Or maybe someone could define filled space.

    As far as I can remember from some popular science books if you look at angstrom scale or less you find out that what looks like solid is actually empty space filled with small widely spaced entities of very small and fuzzilly defined boundaries

  15. reed hs a point on The Myth of Radio Spectrum Interference · · Score: 1

    Based on my poor knowledge of quantum physics I can say that Reed might have a point. This is what I think it means: An electron can only interfere with ITSELF. In the famous double split experiment when one electron passes through both holes it will interfere with itself. However, if two electrons are emmited, one from each hole, they will not interfere with each other. In that sense photons are fundamentally different than waves on the surface of a lake. However I would not know how and if it is possible to make use of this fact to build an antena that distinguishes which photon is which. That is not at all clear from the article.

  16. Re:I protest against this list on Seven Rules For Spotting Bogus Science · · Score: 1
    Just a thought:

    The EPR particle spooky action at a distance and ESP actually might be related. I am not very knoledgable in particle physics but I've heard that larger entities like atoms etc. can be viewed as single particles with quantum properties. If you see two brains as large particles and assume that their are connected (or entangled) in the same way the photons of the experiment we can have some very premature theoretical basis for ESP :-) Brains of twins are good candidates since they start from some kind of entangled situation (like the photons) and "apparently" they exhibit higher ESP activity!

  17. I protest against this list on Seven Rules For Spotting Bogus Science · · Score: 3, Interesting
    I personally agree with is list since this is aproximately how I also evaluate any new idea.

    However, more generally, making rules for evaluating innovation is a dangerous thing. Like art, there are no rules of what is art and what is not and creating rules for that can only be tyrannic. Who's to decide? There are plenty of scientists working alone in their backyard, UFO's might exist, and extrasensory comunication is not much more freaky than the Einstein-Podolsky-Rosen distant-action paradox.

    By the way, this list rules out the validity of religion as well on all seven points :-)

    What you are refering to is called a hypothesis. In science the word "thoery" is more than just a speculation. For instance, the "theory of relativity" is a theory and you can certainly defy it if you manage to pass the speed of light.

  22. In any case, no case for democracy on The Case for the Empire · · Score: 1

    Whoever the good (politically speaking) guys are in the Star Wars, the series is for sure no strong case for democracy.

    It seems to me unprobable that a bunch of elite blue-blooded (I am refering to "the force" micro-organisms) knights and a princess (which implies a royal family) are really concerned about the reeastablishment of a senate, but rather to regain their past benefits which they probably had inherited from a previous kingdom before it turned into a republic.

    On the other side they are fighting a dictator who, unlike Mussharaf of Pakistan, never even at least promised to reestablish democacy after some time and as any dictator is brutal in his ways.

    In the end, if you remove the political factor then the series is about brave knights and a beatifull princess fighting against black dressed evil!

  24. Re:Do we actually NEED this much CPU power? on Intel Promises A Cool Billion (Transistors) · · Score: 1

    Actually, it will be a chlenge to do something with all these transistors. The problem is that as the number of transistors grows, the number of pins to the outside world can only grow by sqrt(#of transistors). So you can do more inside but you you have not enough I/O. That is the current problem in computer architecture. An issue of IEEE computer was dedicated to that. You need special access to see the articles at IEEE but you could do a google search with the title and the paper might pop up.

  25. Re:WTF on Making LCD Displays Snappier · · Score: 1

    Correct, but this only true in the static case, i.e. when the voltage for black has reached the desired value. But, strictly speaking, you will need some power to set the capacitor on the desired voltage. Various things, like the resistance of the wires and the energy needed to move the crystals around (align them or whatever) between the capacitor plates will make you spend some power. The power plug of the LCD is not only for the back light :-)
