WikiProject Physics

See WP:PHYSICS for how to edit Physics articles properly. Probably worth joining the project too. - Alex valavanis 11:00, 24 April 2007 (UTC)[reply]

WikiProject Electronics

Same applies here... WP:ELEC - Alex valavanis 11:08, 24 April 2007 (UTC)[reply]

Quantum Cascade Laser

Are the rate equations the wrong way round? Shouldn't the first one be dn3/dt and the last dn1/dt? Also, I think the rate equation could be specified for a general state as:

${\frac {\mathrm {d} n_{i}}{\mathrm {d} t}}=\sum \limits _{j=1}^{N}{\frac {n_{j}}{\tau _{ji}}}-n_{i}\sum \limits _{j=1}^{N}{\frac {1}{\tau _{ij}}}+I(\delta _{i0}-\delta _{iN})$ ,

rather than repeating it for each of the three states. If the maths looks dodgy, we can talk it through on Tuesday. - Alex valavanis 01:25, 5 May 2007 (UTC)[reply]

Do you still have the xmgrace image file? If so, it would be better if you saved the image as SVG and uploaded the new version to http://commons.wikimedia.org Ta, Papa November 08:42, 25 August 2007 (UTC)[reply]

WikiProject Physics participation

You received this message because your were on the old list of WikiProject Physics participants.

On 2008-06-25, the WikiProject Physics participant list was rewritten from scratch as a way to remove all inactive participants, and to facilitate the coordination of WikiProject Physics efforts. The list now contains more information, is easier to browse, is visually more appealing, and will be maintained up to date.

If you still are an active participant of WikiProject Physics, please add yourself to the current list of WikiProject Physics participants. Headbomb {ταλκ – WP Physics: PotW} 14:57, 25 June 2008 (UTC)[reply]
