Let me quote from the article on page 51 :"According to loop gravity, a light wave cannot be continuous; it must fit on the lattice of space. The smaller the wavelength, the more the lattice distorts it. In a sense, the spacetime atoms buffet the wave. As a consequence, light of different...
Re the article by Bojowald in the October issue of Scientific American about Loop Quantum Gravity. He states that one of the consequences of the theory is that the speed of light is a function of wavelength. Any experimental evidence, or even hint of evidence, that anyone knows of?
Thank you, Marcus.
If that is the case, then could one also think that past a certain point the current universe is completely empty? And could that point be thought of as the "edge" of the universe?
You may be interested in reading Relativity Demystified by David McMahon. On page 161 the following problem is worked out: Consider the Robertson-Walker metric and suppose we take the Einstein equation with nonzero constant, find the Friedman equations.
I don't think so.
First, how does that shielding reduce or eliminate the reactivity of full shell atoms?
Second, let's consider the following:
Chlorine 1s(2)2s(2)2p(6)3s(2)3p(5)
Argon 1s(2)2s(2)2p(6)3s(2)3p(6)
Chlorine forms a zillion compounds,both inorganic and organic.Argon...
Thank you for providing me the reference.
A burning test of this kind is not in any way capable to tell the difference between a mixture and a reaction product, The main reason is that it is a destructive test and thus does not allow you to say anything about the formation of new bonds. The way...
Mr.Chiefy:
According to my Handbook of Chemistry and Physics,the change in boiling point with pressure is given by:
\deltat=(273.1+t)(2.8808-logp)/phi+.15(2.8808-logp)
where t is temperature,p is pressure and phi can be obtained from a graph. I picked 4.7 for cyclohexane and 4.6 for toluene...
Your teacher's statement is perfectly correct. Whether you stir or not,crystallization will not take place. That is assuming that the temperature does not change and there is no evaporation. It is a good example of increasing entropy.
I am not quite sure understand your post. The only reason for vacuum distillation as opposed to atmospheric pressure is that because the boiling points are lowered, it is possible to operate with less thermal decomposition.
The green color is due to the presence of boron and tells you nothing about the presence of borate ions or any other ions. It is unlikely that you formed any isopropyl borate without any cooking of the solution.
