Scientists ‘freeze’ light for an entire minute
—
In what could prove to be a major breakthrough in quantum memory storage and information processing, German researchers have frozen the fastest thing in the universe: light. And they did so for a record-breaking one minute.
It sounds weird and it is. The reason for wanting to hold light in its place (aside from the sheer awesomeness of it) is to ensure that it retains its quantum coherence properties (i.e. its information state), thus making it possible to build light-based quantum memory. And the longer that light can be held, the better as far as computation is concerned. Accordingly, it could allow for more secure quantum communications over longer distances.
Needless to say, halting light is not easy — you can’t just put in the freezer. Light is electromagnetic radiation that moves at 300 million meters per second. Over the course of a one minute span, it can travel about 11 million miles (18 million km), or 20 round trips to the moon. So it’s a rather wily and slippery medium, to say the least.
But light can be slowed down and even halted altogether. And in fact, researchers once kept it still for 16 seconds by using cold atoms.

University of Rochester students protest professor who backed Limbaugh
A new manifestation of the Sandra Fluke case: Thirty students created a wall between professor Steven Landsburg and his class, after Landsburg voiced support for Rush Limbaugh’s insulting descriptions of Georgetown student Sandra Fluke. In a statement released to staff and students, University president Joel Seligman was also quick to condemn the professor’s comments, saying, “we are here to educate, to nurture, to inspire, not to engage in character assassination.” (photo by Jesse Partrick) source

The Glo interactive nightlight has removable illuminated Glo balls that fade to dark after 30 minutes. They have nothing electronic in them so they don’t get warm and they won’t break.

I want this. I really want this.

When a thief forced you to take money from the ATM, do not argue or resist, you might not know what he or she might do to you. What you should do is to punch your PIN in the reverse…Eg: If your PIN is 1234, you punch 4321.The moment you punch in the reverse, the money will come out, but will be stuck into the machine half way out and it will alert the police without the notice of the thief.Every ATM has it; It is specially made to signify danger and help. Not everyone is aware of this. Reblog this and share to your friends.

I did  not know about this. neat. 

Is…this an actual thing.
Um. My PIN is a palindrome.

Good to know.

Just checked.
