Quantum Physics For Everybody 145

fiziko writes in with a self-described "blatant self-promotion" of a worthwhile service for those wishing to go beyond Khan Academy physics: namely Bureau 42's Summer School. "As those who subscribe to the 'Sci-Fi News' slashbox may know, Bureau 42 has launched its first Summer School. This year we're doing a nine-part series (every Monday in July and August) taking readers from high school physics to graduate level physics, with no particular mathematical background required. Follow the link for part 1."

Comment Re:Doesn't matter. 3D in the browser is stupid. (Score 4, Interesting) 198

We realized that 3D graphics in the browser were stupid and useless back in 1995...

...and slow! I was there when VRML was landing (just finished high school) and all I saw it used for were virtual rooms were avatars would talk in a 3D IRC like environment. Only big problem back then was we didn't have 3D acceleration and the interface was clunky and painfully slideshow like in speed.

As for uses, I could think of a few and have already started coding them. Instead of loading a PNG or GIF, it is pretty nice to be able to download a float array, be able to display it, and allow a user to interrogate it. Giving a user that kind of capability in the browser while not requiring them to download an application or a browser plugin is pretty darn nice. And while not mainstream, scientific fields could greatly benefit from something like that.

Comment You Were Starting The Game Wrong (Score 2, Interesting) 398

The new Prince of Persia reboot ensured that I won't buy a PC game from Ubisoft ever again. It suffered from the same "Let's fill the UI with references to console-controller buttons" issue.

I had the same problem if I started the game from a shortcut I created to the executable. If I used the launcher from the game disk, all the UI references to the console controls went away.

With respect to the port, I played it on both the PC and the PS3 and enjoyed the PC version since the graphics were very crisp compared to the console and I like the mouse/keyboard combo.

Have both parties present documentation on their legal bills. The prevailing party, having also won the fees receives the lesser of the two amounts.

Assume we have Joe vs MegaCorp and Joe's legal bill is $1,500 and MegaCorp's is $400,000.

If Joe wins and is entitled to fees, he gets his entire $1,500 (in addition to any damages). If MegaCorp wins, they get their damages plus the lesser of the two legal bills ($1,500). This promotes efficiency throughout the system.

Corporations will be incentivized to match their legal spending with the size of their "target."

This is good advice, and gives me an opportunity to speak to the community at large: some of us who go to cons and are in a position to shake tons of hands politely decline. It's not because we're being dicks, it's because we know it's a good way to substantially decrease our chances of catching and spreading any germs.

Comment Oh, cruel irony (Score 2, Interesting) 374

I played the PAX Pandemic game, where the Enforcers handed out stickers to attendees that read [Carrier] [Infected] or [Immune] (There was also a [Patient Zero].

I got the [Immune] sticker, and by the time I got home on Monday, it was clear that I had the flu. I've had a fever between 100 and 104 all week that finally broke last night, but I'm going to the doctor today because I think whatever I had settled into my lungs. I'll tell him about the H1N1 outbreak and get tested if he wants to run the test, but at this point I think it's safe to assume that I was [Immune] to the Pig Plague, but definitely [Infected] with the damn PAX pox.

Even though it's been a week of misery, it was entirely worth it, and I don't regret going to PAX for a single second.

Music

Pandora Stabilizes, No Longer Completely Free 268

AbyssWyrm writes "Yesterday, Pandora founder Tim Westergren announced that the music service was on safe ground once again, but will no longer be free for all users. Instead, it will be really cheap — for those with a free account, there will be a cap of 40 hours per month, and a user may pay a one-time fee of $0.99 to resume unlimited listening to music for a month. According to the blog entry, this will affect the top 10% of listeners. Certainly not a bad deal considering the price, and I suspect that Pandora is one of few free internet resources whose users are loyal enough to pay a small fee to keep it afloat. Pandora's future had been uncertain ever since the royalty rates for internet radio were increased in 2007."

Comment Statistical significance in surveys (Score 5, Insightful) 555

Surveys are inherently difficult to present in a neutral fashion, especially when attempting to determine correlation. Take the following (simplified) survey for example:

I like Cheerios:
[Yes] [No] [Sometimes]

Rate your proficiency at math:
[Excellent] [Good] [Average] [Poor]

Now, let's say you found a statistically significant correlation between people who like Cheerios and people who are excellent at math. Congratulations! You just did not find a correlation related to math proficiency at all.

What you did just find is a correlation between people who selected the first option in your survey.

Now, randomizing your answers is a good start and will resolve the above issue. However, there are hundreds of other things which can affect your results and there is an entire survey industry formed around these problems. The immediate problems that spring to mind about the survey in TFA is:
-Respondents must have internet access
-Respondents must have signed up to Amazon's mechanical turk
-Respondents were paid for the survey
-Respondent proficiency at math/language was self-assessed
-Respondents must be able to comprehend English

Anyway, I could go on but my point here is this: despite the fact that a statistically-significant correlation that was found, that correlation may not stem from the questions themselves.

How Do You Greet an Extraterrestrial? 803

The LA Times is running a story about Earth Speaks, a companion project to SETI, which focuses on how we would communicate with intelligent extraterrestrial life, should we happen to discover it. Far more effort has been devoted to searching for signals or a means to communicate than the question of what we might say once contact is established, and the folks at SETI have set up a website to gather opinions on what the best questions and statements are. "So far, the messages break down into a few distinct categories. Some people want to throw a block party to welcome the aliens to the neighborhood. Others, less trusting, would warn the aliens that we've got guns and know how to use them. Another group, possibly influenced by having seen too many movies, would have us hide under the bed until they go away. 'If we discover intelligent life beyond Earth, we should not reply — we should freeze and play dead,' wrote one contributor." What would you say first to an alien?
