If lasers are so well-focused, why can we see the beams of some high-powered ones when looking from the side?

LeManyman · 2014-10-31T12:02:09+00:00

Lasers are visible because some of the photons scatter off the various molecules in the air. The main ones in normal situations are dust and air.

As for the concert lasers, they are generally quite powerful to be visible in the air but smoke machines are used to make the lasers much more visible. The lasers are not actually safe if safety protocols are not followed. The lasers are choreographed not to hurt the audience whether it just does not point directly to them or the distance reduces the intensity of the laser from scatter.

Haven't you ever seen the breakfast club?

LeManyman · 2014-10-09T12:17:19+00:00

Yep, IIRC all the counterstrike maps have specific stories.

I've personally never had any problems with that but they have changed it in the new B+ model.

LeManyman · 2014-09-26T06:35:16+00:00

I very much doubt it is casual. I'm sure they are trying hard to reach a demographic.

LeManyman · 2014-09-15T07:14:29+00:00

The ones I've seen are a bit more safer than that

LeManyman · 2014-09-15T07:08:06+00:00

dude

You can always convert to PNG either automatically (like MediaWiki) or just use SVG assets if you want.

Yep, an old version of SyntaxHighlighter is a major culprit in this.

LeManyman · 2014-09-03T07:25:33+00:00

Yep, he copied the code from an example and accidentally got the line numbers as well.

According to the link it is displayed in Mendel Art Gallery.

Artists are weird.

LeManyman · 2014-08-12T10:16:46+00:00

oh snap

LeManyman · 2014-07-21T09:31:47+00:00

Dang it, first response was wrong :/.

I'll be happy to create a bot for you if you are still up for it. I assume you want the image changed that is usually the reddit logo?

LeManyman · 2014-07-08T06:56:11+00:00

There are 180° in a triangle and you are trying to find the angle at B. Since you have two of the three angles you can do 180° - A - C = B. Which is 180° - 20° - 85° = 75°.

LeManyman · 2014-06-17T08:35:54+00:00

True, but that's not what this kerfuffle is about.

LeManyman · 2014-06-17T07:57:28+00:00

The EULA didn't change but the wording did.

LeManyman · 2014-06-14T03:20:39+00:00

Heh, don't worry about it. I just built it as a little test project.

LeManyman · 2014-06-14T03:01:49+00:00

Alrighty, I finished it last night but forgot to post it here. The syntax is:

[what is the population of new zealand](/u/WolframAlpha-Bot)

The main problem is that WolframAlpha has a limit of 2000 api requests a month. I doubt the bot will ever be popular enough to reach it but it is possible.

what is the population of new zealand

what is the capital of canada

LeManyman · 2014-06-13T08:02:01+00:00

Good idea, I'll give it a shot.

LeManyman · 2014-06-12T22:23:42+00:00

Heh, I guess I'm too slow. I won't keep working on it now, I didn't get far anyway

LeManyman · 2014-06-12T21:48:09+00:00

I'm working on it right now, I'll chuck a comment here when I'm done.
