Re: at the same mW which color have more burning p Exactly. If you have a 100mW red or blue, makes no difference. Yet there are some factors to consider. Depending on the colour of the material, some wavelengths might get absorbed better than others. Also, burning needs focussing, and the...

"...and the things that concern you...hahaha, pun intended? yup, a 13yr-old whipping out a multiwatt laser would get me concerned...but then again, any age would.

...and the regular background image of stars and galaxies would reappear.

Re: Possible GB Green, Blue, Red and Yellow lasers Well, I am interested in either blue or yellow (or green, why not?), but am on a rather tight budget. Can you say any more approximate prices, or percentages off the LG price? would be nice if you could send me a short PM on what to expect...

You'd need to further define that. I bet if you were to offer $500k for someone to design you a red single mode diode, powers might go pretty high...who knows, maybe you'd get a 10W single-mode diode that is just too expensive to manufacture/research. Also splits hairs about "commercially...

Re: Hex DIY Red Laser - The ULTIMATE burner idea! Just a little off-topicish sidenote here: Did you know the DX green pen laser's (the standard DX30s etc.) modules have the about same diameter the Aixizs have? So you might be able to turn this thing into a 210mW greenie with 7 DX30s, higher...

But I think you would have to look forward to "collect" the 1-yr-old photons flying before you. @BlueFusion: I don't think it's that easy, maybe look up "http://en.wikipedia.org/wiki/Image:Dice_analogy-_1_to_5_dimensions.svg" or generally the 4D-topic on wikipedia. Problem is, the cubes would...

What did you expect? That Senkat's style of writing would all of a sudden decrease to that of a minor? I mean, as riddle, his choice of words was maybe "not perfect", but it still was "proper english". The new user "senkat" on the other hand wrote in a way that showed that the author was...

Unfortunately, very true. I was once at a kid's camp, and my room-mate saw it (age >20), and then went around to all the grown-ups telling them it was an electric toy guitar, they were to hold it, push the button and hit the "stings" and it would make a sound...everybody did it...

Yup, that's right - my calculator doesn't emit weird sound waves out of nowhere ;) scnr, I know what you meant. I think youn are right with the gravitational lens - it's misformed space, not the photons being bent. About E=mc²: From what we learned, it is a generally valid equation - depending...

Bold statements, young Jedi! Okay, I dare you to a) get me a 3D-Model of a 4D-world. b) prove me wrong when I say "there is no 4th spatial dimension". By the way: your first statement implies there is a fourth dimension of space. Also, it isn't really that hard to picture a fourth dimension...

Re:  BRAND NEW APPLE IPHONE 8GB AT JUST.....$ *-* duh?

Yup, that describes the situation pretty good! @Morepower: The way reflection works: There are two concepts of reflection in my head, and I am unsure where to apply which: On the one hand, light is a (radio-)wave. So this "Radiowave-at-visible-frequencies" flies into a mirror. Now when this...

Well if you add them parallel, that means vour maximum voltage would be higher (if you were using two 1000V caps, you could load 2kV. But don't know about different caps). Still, the total capacitance would be the reciprocal sum (i.e. 1/(1/C1+1/C2), or if you were using a 200µF and a 500µF...

Re:  BRAND NEW APPLE IPHONE 8GB AT JUST.....$ ...on most forums, a thread like this wouldn't even get the chance to see the light of day, lest the chance to get continued and filled with more spam.

Yup, I was gonna post the exact same thing! Got one of these and modded them with two photo flashes. You can really her how slow it is charging them up, but once it was ready I tried zapping a bug...nothing! Tried shorting it with a metal contact...are you kidding me? That was a huge freakin...

Well, I guess we better start donating to al qaeda so that they will not use lasers for their terroristic atcs as well as that they will not equip any laser-countering measuers so that the American Patriotic Terrorist Defense Forces can stop them with lasers and high-power lasers will just be...

Well, photons do have mass, or else you would have trouble setting up a gravitational lens. You can calculate their mass by solving E=mc² for m, and say E is the photon's energy (h*f). Actually, photons are not so special, if you start considering De Broglie's wave equation which says everything...

I doubt it's just you...

<- doesn't see any bottom buttons... Anyways, I didn't notice in the first place, but it is loading much faster. Icestorm does seem to be decent :)
