How can you pass a straight rod through a curved hole? No, neither of the two are pliable. This demonstration at the Science Museum in Valencia, Spain, shows you in just a few seconds. This reminded me of a hyperboloid, which I discovered when writing about math shapes.
What mathematicians call a hyperboloid of one sheet is a really cool structure that is made up of many (actually an infinite number) of perfectly straight lines that look to us like a curved structure. First, imagine that you have a cube. Stand it on one of its corners and spin it like a top, then look at it from the side -the sides seem to be curved, but you know they aren't. Now, take a handful of uncooked spaghetti noodles. Use two hands, and twist the strands loosely. It forms the shape of a hyperboloid structure, which looks like a cooling tower at a nuclear reactor. All the spaghetti noodles are still straight, but the shape of the handful is curved. In architecture, this idea enables builders to produce curved structures by using straight line supports.
The museum display is the same thing, only they are using one straight support in motion instead of an infinite number to build a structure. The animation here helps to connect the two concepts. -via Viral Viral Videos

If banks "don't need it anymore," why do they even pretend they are a business providing a service?
Actually yes. Yes, I would. (Also, sir, may I strangle you?)
I hope every single one of his customers take their money out of his shitty bank.
Want to do something meaningful to protest Wall Street? Close your account with big banks and open one with a credit union. You will be so glad you did.
Penalty for early withdrawal . . . Almost zero interest on my savings, checking and CD's . . . Give bad loans to people who won't pay it back . . . Passing costs on to small business owners . . . Still have scabs on their knees from begging the government to bail their insolvent a$$ out . . . Dumb hours . . . Rotten customer service . . . High interest rates on credit . . . AND NOW THEY WANT TO CHARGE ME FOR A DEPOSIT?
Sorry, Larry, Curly and Moe have already made that movie. At least they made me laugh.
The whole banking system is gridlocked, too nervous to do anything but think up new ways to scam their customers. Perhaps we shouldn't be so surprised with this latest one.
Do we need more proof that the financial/banking system we have in place today does not work? This is getting absurd.
The people that such a policy will effect are the very same people being call "job-creators" by the gop and need to get larger tax breaks because they invest all this excess cash.
I know some bank have started charging for transactions that require a teller which is just really silly.
But on a marketing point of vue : WTF?!!!
My checking account is already a loan from me to the bank at 0% APR, which they then loan out at substantially higher rates. There's no f&*%ing way I'm going to pay them a monthly fee for the convenience of having access to my money.
I've now switched to USAA credit union, and sent SunTrust a detailed explanation of my view of the matter, and pointing out that they're losing--no, they HAVE LOST--a 16-year customer over $12/month.
