    Nobelprize for quantum optics

    Thanks for the references marcus, i was somewhat disconcerted by the AP feed (a snippet here): "Until Glauber published his theories in 1963, scientists dismissed the idea that quantum theory, which was developed to describe the behavior of particles, had any application to light. But...

    MathType to create different types of mathematical documents

    Your MathType can be used here, check out the "preferences... translators" and export TeX-LaTeX to a text file. All that needs to be added is the start and stop LaTex strings. Then post the text here. This one done in MathType: \mbox{\Huge \[ e^{jz} = cosz +...

    Applying Simpson's Rule to Data Historian Sampling

    I suppose this is too late to answer, wish i had seen this before. You don't need to use Simpson's rule to begin with. Just use rectangular rule. So if one measurement is say 9.3 gal/sec and you measure between 10 sec; 9.3gal/sec x 10sec=93 gallons, then move to next step. Next up approx is...

    Mathematica How to simplify an expression in Mathematica

    Remember: \[ \sqrt {a^2 } \ne a \] And it won't do this invalid operation. Best

    Cancel Microphone Noise w/ Lowpass Filter | Help Needed

    Maybe bandpass, the mic sometimes picks up low freq garbage like breath and/or wind. Try low freq about 300 hz and high at 4 khz. You will have to read the help file to set coef. Good luck.

    XNOR Gate: The Combination of XOR and NOT Gates

    Seems a little odd to me: maybe it's a NXOR or \mbox{\Huge \[ \overline {XOR} \]} Best

    Applications Of differential Equations In Physics

    Differential equations ARE physics, well, almost all differential equations are derived for physics to model a physical system. http://www.sosmath.com/diffeq/modeling/modeling.html Best

    What Scientists Believe is the Purpose of Life

    Unfortunately, scientists do not have the faintest idea what life is. There is something we have not measured. Take this gestalt: if we had a very good ctem and we could place individual atoms at specified coordinates in space : if we put all the atoms in the correct location for an...

    Ploting zero order Bessel function

    Looks good, you have derived the small series representation for Jo : \mbox{\Huge \[ J_\nu (z) = \left( {\frac{z}{2}} \right)^\nu \sum\limits_{k = 0}^\infty {\frac{{\left( { - z^2 /4} \right)^k }}{{k!\Gamma (\nu + k + 1)}}} \]} Unfortunately, this will only converge up to about...

    Degaussing Ships: What do You Know?

    self, that's a great WW2 story. Do you have reference for Axis powers producing a magnetically steered torpedo ? A reference to Allied ship with wires wrapped around it ? This was not common practice. The U boats were point and shoot. And that worked for about 25000 ships sunk. Some kinda...

    What Scientists Believe is the Purpose of Life

    When i was in school, i took eight philosophy classes besides the subfields of mathematics and physics. Ah! you seek consensus ! Whack on the head with ruler !

    Speed of Gravity: Experts' Opinion

    There was a measurement of gravitational wave velocity a year or two ago .. can't remember reference but it was in this solar system. And it found approx c.

    Increasing capacity of hard drive partition

    No. You will not gain speed via putting the swap file on another partition on the same HDD. Think about the pickup head must fly between partitions .. back an fourth. Put the swap on another drive is the only way to gain speed ... the head remains over the needed area to read/write. Better to...

    What are the implications of time travel in popular culture?

    "Time machine could never exist because someone would come back and destroy it before it could be developed?" No, someone would come back and invent it before it was invented. Best

    News How long until the left labels Zell Miller a traitor?

    "For one thing, the list of weapons systems Kerry voted against is a little misleading." Kerry is not a hawk, he is a dove and you know it. Always prefering over 20 years voting record to prefer social programs vs defence programs.
