“I’m majoring in engineering. AP stat class was soooo hard”

Hey bro you might want to change your major But Uh Yup

I figure this post is a good excuse to tell a story I hear often in our physics department (well, you might have heard it before but it’s a good story so listen again). 

A bright eyed freshman comes to the university majoring in physics, saying that they love science but hate math.  By “love science” they usually mean “science fiction” rather than science.

They drop out so quickly it’s hilarious.

Also:

Another gem: Both the Engineering major and chem major agree that math isn’t their thing

What are you doing

Chemistry majors at my university actually don’t have to take very much math at all (12 credits of math, compared to the 22 I have to take and the 16-19 that engineers take), and I think they don’t necessarily have to take it right away as an Engineer would.  They just need to have multivariable calculus and introductory electromagnetism for physical chemistry, which is a senior course anyways.

That poor engineer though.

So, in the “headcount” scene of The Avengers, Tony Stark puts on a pair of metal wristbands (let’s just call them bracelets, that’s what they are), and later uses them to put on the Iron Man suit. No big spoiler there, yes, Stark wears the Iron Man armor in The Avengers.
As it happens with movie props from time to time, instead of fabricating something new, they go out and find something that already exists and use that, or starts with a real world item and goes from there.
In Star Wars: Episode, Qui-Gon famously spent a lot of time talking into a Gillette For Women SensorExcel razor handle with some spare LEGO bits and parts from an unfinished Ikea computer desk glued on.


In Terminator 3, they crank up a particle accelerator with the throttle from a Saitek joystick:

So anyways, in The Avengers, Tony slaps on some jewelry, which turns out to be a pair of MAGTITAN NEO LEGEND Power Bands from Trion Z. They are made from titanium and stainless steel, decorated with carbon fiber and coated with a protective resin. 
ThinkGeek (among other places) is now selling them. 
So why is this a bad thing?
Well, “powerbands”, along with similar products, are compete bullshit products. They contain very strong magnets inside under the theory that their orientation will cause the magnetic field around you to shift, allowing for things like “more harmonious energy flow” in order to “increase vitality and wellness”.
You’ll notice words like “vitality” and “wellness” used when talking about these things, because they don’t actually mean anything. You can’t measure vitality. It’s a nonsense word in terms of science and health.
In fact, go to the Trion Z website and try to find any mention anywhere on the site about what their bands actually do. The closest they say is that there are magnetic fields everywhere and their bands create negative ions. They never make any claims about what those ions do or what benefit they have, because they aren’t allowed to. Any claim they make would have to be backed up by science, which simply does not exist for these sorts of things.
So what we end up with, through licensing deals now, is a company selling bullshit sham pseudoscience at $200 a pop is getting promoted by the biggest movie of the year.

And they are even making money off the kids:

Now I really wish someone had just bent some metal and made him new bracelets.

I found another terrible blog theme, it doesn’t allow for moving through pages on Firefox, which is very annoying.

A couple of fine folk I know are celebrating their fourth anniversary! Every year so far, they’ve commissioned one of their artist friends to do a commemorative piece for it, taking turns and surprising the other person with their choice. This time around, the fella chose me, and wanted it done in the style of the bus stop scene from My Neighbor Totoro:

It was completed this weekend, but I wanted to wait until I was sure it wouldn’t spoil the surprise for the other person!

Don't play public games on Diablo 3

soselfimportant:

fugiman:

Due to a security hole, bots can scrape your session ID from a public game, then use that to log in as you. This bypasses the authenticator, and allows them to steal all your gold and items. Unsure if they can buy things off the Real Money Auction House or not, but I wouldn’t risk it.

As long as you are just playing with friends or single player, you should be fine!

whoa! thanks dude!

wow this is good to know, I was planning on doing some public games too, hope this gets fixed.

edit:  apparently it’s not just public games/potentially not involving public games according to the official forums.
