Do you like films about gladiators?

you see - the kettle will boil at a constant rate whatever

however this may not be true - as if you are looking at it you may be absorbing more photons and thus more energy then if you were not as such by the mere act of looking (or observing) you are altering the system.



probably


thats another one!

There's an idea, when our eyes capture photons, are they actually captured or merely observed?

If the photons are captured then the room would get darker if we all had our eyes open! Scary! Stop stealing my photons!!! Shut your eyes!!!

The eyes would be like little black body's, absorbing visible light and emitting light mostly in the infra red. Although every now and then a visible photon might get emitted. So the room would get darker in visible light and brighter in invisible light.

Wow, we're emitting infra-red from our eyes!!!

Like a death ray!!! Well, more like a "doesn't hurt a bit ray" really...

[original PM]

but surely we do 'capture' the photons as do we not turn the energy into what we see as visible light when the photons impact on the cones n rods at the back or our eyes?

need a biologist to sort this one --- any takers
