So what's happening is a high speed polymerization reaction initiated by the action of laser light.
An infrared beam moniters the amount of unreacted acrylate double bonds. But what is an acrylate double bond? Am I correct in saying that a double bond absorbs IR radiation?
The double bond...
I wish I could feel the beauty in the mathematics of order in nature also.
Profound! Thank you for sharing the time to express your thoughts on Gods creation. :smile:
I will certainly go read about number theory, it will be a long struggle haha, but worth it I know!
Five years in college studying physics, yes of course I would regard mathematics as a science. Mathematics describing the trajectories of particles/projectiles ie. trigonometry, dynamics of systems, rates of change in calculas, vector and scaler fields such as electromagnetic waves and...
My answer I keep on obtaining for the De Broglie wavelength seems to be ridiculous. 3.2x10^-46
I am using p = sqrt [(Kinetic energy)^2 + (2(rest mass)(kinetic energy))]
and lambda = h / p
rest mass of electron 0.511 MeV (0.511 x 10^6 eV)
Relativistic or Classical?? Calculation of De Broglie Wavelength
Hi there,
Okay, the question is: Calculate the De Broglie Wavelength of a 10 MeV proton and a 1 MeV electron.
How does one know whether to use relativistic or classical means?
Relativistic => Kinetic / Rest mass >/ = 10%...
Ok, am I right in suggesting that the 'density of states' is, how closely packed the energy levels in an atom are, or is it how closely packed the energy levels in the material as a whole? That is, the energy gap between the valence band and the conduction band?
No betelgeuse is the red supergiant star situated diagonally to rigel. And it was in the south when was I trying to align it.
The image I have attached indicates how the scope is aligned initially when pointing at polaris in the north. Is that right?
The tube points to the west on the horizon.
Yes its on a CG-5 mount.
I mean the counter weight bar is pointing down and the optical tube is pointing at polaris. And the index marks (the two pairs of triangles are aligned with each other).
Hi there,
I am using a celestron C11. But I really need some help with aligning it up through auto 3 star align.
The counter weight bar pointing approximately due north with the index marks aligned and locked.
I aligned the eyepiece with the finderscope on polaris.
I set the exact...
Yesterday I burnt a movie to a dvd using windvd, so last night I went to watch it downstairs in the dvd player, it turned out to be very choppy and a result of the choppiness there was a delay in the sound.
I have a P4 with 512mb RAM in a new laptop. Whats the problem? Anyone else use windvd...
