comment How do Optically Active Compounds Rotate Plane Polarized Light?
To address the second part of your question, it's possible to determine the specific rotation of a compound using time-dependent density functional theory (TD-DFT) as it drops out of the first-order polarisability. Steven Bachrach has quite few blog entries on calculated specific rotations, including one of 4000 degrees by Henry Rzepa!

comment Apple falls for which of these 2 reasons?
Consider what would happen on the 'trailing' side of a planet, in the case of explanation #2. Apples, people and pretty much everything else would not have an easy time of it.

comment Quantum entanglement faster than speed of light?
You cannot change the spin on one particle and get a corresponding change on the second particle. Niel de Beaudrap sums it up very well as a 'correlation of random results'. Once you make a measurement (i.e. interact meaningfully with one of the entangled particles) the entanglement is collapsed.

comment What is the relationship between AC frequency, volts, amps and watts?
'amperage' is an evil, evil word for 'current'. Although I suppose voltage is also an evil yet alluringly bisyllabic word for 'potential difference'. I guess everyone can call them what they like, but I find 'current','potential difference' and 'power' to be far nicer from a self-description perspective and more helpful in getting an intuitive feel for their interrelation. This said, freqency should definitely be called 'hertzage' :P

comment What is changing in latest light bulb technologies?
@ Mark Booth: Yeah, you're right, I'm amending the answer. I found a chart that illustrates your point nicely, not for a CFL but for a fluorescent tube.

comment What is changing in latest light bulb technologies?
Incandescents were recently phased out here in Australia. Just be aware that CFLs contain a (tiny) quantity of mercury and thus should be recycled properly.
