Yes, sorry, Bq and Hz are different units, same dimension (different name for the same concept).

To elaborate: a "collision" is not a physical quantity, so it doesn't have a unit. Which leaves you with frequency (Hertz), which is actually a kind of artificial unit (derived), since it is any event per second.

Short answer: yes. We have several applied) physicists working here in CFD. A software package is just a tool and software is not hard to learn. It is much more important to learn what you want to model: you need to understand the physics of the system to know which parameters you can tweak. A...

Hi Sredni, Sorry to disappoint you, but as I mentioned, I'm not in the Lighting division and my knowledge of those details is limited to the basics of (organic) LEDs. I happen to know about the applications because I've had some contact with the people involved at Philips Research.

Hi Brainiac, Before I answer, I am obligated to full disclosure: I work at one of the product development sites of Philips, though not in the Lighting sector. I do know about Philips Lighting offering special solutions for e.g. greenhouses, all done with specially tuned LEDs, like CWatters...

Hi there. I thought I already had an account here via Physorg, but apparently not ;-) I have an M.Sc. in Applied Physics and I'm currently working in product development. Signed up here for the occasional discussion and maybe helping out students if I can.

As for your first question: If you are asking if it is possible for more than one time dimension to exist: yes. There is no reason for us to rule that out beforehand. However, like any proper hypothesis in science, you would need to be able to verify or falsify the statement. As far as I know...
