Cloaking and Our Seven Common Mothers

Cloaking

I'm sure by now you've heard of the experiment producing a successful time cloak. Moti Fridman and colleagues, at Cornell University in Ithaca, NY, created a hole in time using the temporal equivalent of an invisibility cloak.

Invisibility cloaks are produced by distorting electromagnetic fields in extreme ways, moving light around an area, so that it can't be seen in that area. Physicists have used them for light, sound and ocean waves. There's even an illusion cloak which makes an object look like another object. Excellent.

Granted it took a huge amount of energy and a huge-ass machine to create the time cloak for only a fraction of a fraction of a second. But that won't last.

Fridman says there might be a use for a time gap lasting fractions of a second in routing competing streams of data to a processor. For more on cloaking and links, SEE.

DNA - The Seven Daughter of Eve by Bryan Sykes. This is not so new, published in 1994. It's still a fascinating read. Bryan Sykes is the professor of genetics at the Institute of Molecular Medicine at Oxford University. His collection and analysis of our genetics through the mitochondrial DNA passed on from mothers to daughters has shown us all to be descended from seven common Eves or mothers. He calls them Helena, Katrine, Xenia, Jasmine, Velda, Ursula, and Tara. Who knew a book on DNA could be so fascinating? I found it so. Yes, I read the whole book.

What could you imagine using a time cloak for? What about an invisibility or sound cloak? An illusion cloak? Have an idea for a cloak of you're own? What do you think about our shared genetic ancestry?
