What about them?

Photons only have "mass" when in relative motion to the observer due to their energy [E=mc^2 --- m=E/c^2]; otherwise they wouldn't "exist" at all. Electrons still have mass even when at rest (except, of course, quantum-level motion) relative to the observer. This was demonstrated by Millikan's Oil Drop Experiment. Electrons at rest can be easily observed as common static electricity.


Many o' misconceptions on this fine day.

1) m = 0 for photons. Period.

The full energy-momentum relation in special relativity is E^2 = [pc]^2 + [mc^2]^2, not E = mc^2. So please don't argue that photons have mass through E=mc^2.

Read this page. This details the theory and consequences of a massive photon.

2) Millikan's oil drop experiment showed that charge is quantized. It had nothing to do with the mass of the electron.

That´s not right, because a photon has mass, not much but it have (see neutrino has alreadyy a little mass). Only particles with absolutely no mass (i don´t know a particle with no mass) shouldn´t affect by a black hole.



I bet they could. (neutrinios escape a black hole, that is)

I'm not saying that I can 'prove it' using physics, hand gestures or a combination of physics and handwaving. But, if they have 'no mass' then the black hole gravity shouldn't really affect them.

So, experimentally, a neutrino is a theoretical particle which makes heavy water give of a flash of light. Neutrinos might have an issue of going throught the ground up atomic/subatomic matter inside a black hole, but I suspect that the 'no mass' aspect of neutrinos makes them great at escaping the gravity from a black hole.



You are oh so wrong.

Photons are massless. Theory demands it and it is consistent with experiment. The smallest upper bound on photon mass is something on the order of 10^-17 eV.

Neutrinos are massive - all three of them. WMAP data places the sum of the neutrino masses at about three quarters of an electron volt.

pdg.lbl.gov is a great place to start looking.

Gravity couples to any kind of energy. Mass is not required. Any particle - massive or otherwise - will be affected by a black hole. Unlearn what you learned about Newtonian gravity, it is incorrect.

Weird.

BOINC says "no work from project" when I update, but frontpage says ~40,000 WU available. What gives?


Not wierd at all!! :). Just read it more carefully!! :)


Argh.

Reading is hard.

OK Neasan --

Curiousity forces me to ask: with milk or lemon? Any sugar ???


Lemon? Jaysus no. Milk and two sugars(I'm slowly rotting my teeth)


Milk cancels out sugar. The former is good for your teeth, the latter rots it.

At any rate, the update is appreciated, Neasan.

I think statistics in BoincSinergy and BoincStats doesn't reflect the correct number of credits. Something similar occurred in nanohive project time ago and was caused by a change in the project's URL. Then someone (I supose the administrators of that project) informed the new URL to the admins of BoincStats.


Stats aren't being updated? NO SHIT.
