Just a thought on photon energy and proper time

Had a minor revelation this morning.  About fundamental physics.  Yes, I'm weird this way.  Thanks for noticing.

Photon energy (best known as wavelength or frequency) times proper time (local flow of time) is a constant.  As gravity increases, proper time decreases, and photons gain a proportional amount of energy.  We call this blue shift.

As gravity decreases, proper time increases, and photons lose a proportional amount of energy.  We call this red shift.

Interesting.  It's almost as if gravity has no influence on photon energy - just our perception of it. 

Relative velocity still does alter photon energy.  A photon emitted in the direction of travel still has more energy than a photon emitted in the opposite direction, from the standpoint a stationary particle used as a target.  Of course, that's probably because of the energy differential caused by the velocity deformation around the emitting particle.

So, the only way to tell the actual energy of a photon, is to intercept one emitted at exactly 90 degrees to the path of travel of the emitting particle, along an equal gravitational gradient, by a stationary particle, or one traveling at ninety degrees to the angle of interception.  In that (and only that) circumstance, the energy delivered by the photon will be exactly equal to the energy it was emitted with.

A new job for the EPA and FDA

From a comment by Frank Luke at John Wright's Journal:

"A is for Alar." I remember the 60 Minutes story about Alar like that used on apple trees caused cancer in lab animals. While we were in high school, a friend of mine in FFA gave a speech about his research into pesticides and scare tactics. Alar was his golden example. To get the results it did, the lab gave the mice so much Alar that a human being would need to eat 14 tons of apples a day for 70* years. In that dosage, 5% of the mice developed tumors. In the group having a half dosage (meaning the equivalent of 7 tons of apples a day for 70 years), none developed cancer.
At that statement, the audience went into shock. Half were trying not to interrupt him by laughing at the dosage required. The other half just gasped.
*This is 20+ years ago. My memory may be off on the exact numbers, but "tons per day" and "years" was definitely in the speech.

I propose a new executive order for various government organizations such as the EPA and FDA.  They are to propose no new regulation, ruling, finding or guideline until they have completed an open, replicable, scientific evaluation of all previous rulings, regulations, findings and guidelines.  Study summaries are to be written in plain English, at no more than a 10th grade level, and made freely and easily available to the public.  Each study is to be reviewed by a panel of thirty randomly selected citizens, who are neither government employees nor receiving welfare benefits, with SAT (combined math & verbal) scores of not less than 1000, or ACT overall scores of not less than 20.

Review: .224 Valkyrie

.224 Valkyrie is essentially a .223 redesigned to better handle long for caliber bullets.  It produces similar velocities for the same weight of bullet as a .223, but .223 cartridges can't really handle 95 grain bullets.

If you're really into long range, precision shooting using the AR-15 platform, this caliber will be a good investment.  Unlike most of the other new .22 center fire cartridges, the Valkyrie doesn't come with additional recoil or overall length.

Otherwise?  It doesn't really bring much new to the table.  It might make a decent military round, but increasing the caliber (to at least 6mm, preferably 6.5) would be a better solution.
