‘Twisted’ waves to increase bandwidth??

This from BBC:

‘Twisted’ waves could boost capacity of wi-fi and TV

The approach, described in the New Journal of Physics, could be applied to radio, wi-fi, and television.

The parts of the electromagnetic spectrum that are used for all three are split up in roughly the same way, with a spread of frequencies allotted to each channel. Each one contains a certain, limited amount of information-carrying capacity: its bandwidth.

As telecommunications have proliferated through the years, the spectrum has become incredibly crowded, with little room left for new means of signal transmission, or for existing means to expand their bandwidths.

But Bo Thide of Swedish Institute of Space Physics and a team of colleagues in Italy hope to change that by exploiting an entirely new physical mechanism to fit more capacity onto the same bandwidth.

Here is a link to Bo Thide’ nice personal page.

PS., I wonder – whether this could be applied/observed in Neuroscience and in the way individual neurons communicate with each other, particularly while processing large-scale network activity?

Internet Explorer users are “Dumb”… LOL!

 

Are users of other Web browsers smarter than the people who use Microsoft’s Internet Explorer?

A new survey doesn’t quite say so. But it sure as heck suggests it.

The survey by AptiQuant, a Vancouver-based Web consulting company, gave more than 100,000 participants an IQ test, while monitoring which browser they used to take the test.

The result? Internet Explorer users scored lower than average, while Chrome, Firefox and Safari users were slightly above average.

And users of the more obscure Camino and Opera browsers, as well as those using Explorer with Chrome Frame (a plug-in designed to let users view emerging HTML5 content), had what AptiQuaint called “exceptionally higher” IQ levels….

Is Bhagavad Gita a Buddhist scripture?

I am reading a book on Hermetic, Pagan and Esoteric Beliefs, and in this book, the author David V. Barrett writes (in Page 30):

…. She wrote a number of influential books, including Esoteric Christianity, Introduction to Yoga and a translation of the Buddhist scipture the Bhagavad Gita…

and I have been thinking whether Bhagavad Gita is a Buddhist scripture!?

I went through many articles and reports on the similarities and differences between the teachings and beliefs of Buddhism and the Bhagavad Gita. Also there are interesting arguments on the chronology.. I don’t know (I’m not an historian or a literary or religious scholar). But I can just say the Bhagavad Gita is a great book and the teachings of Buddhism are equally great.

And this book by David V. Barrett is a good book too.. I’m enjoying reading it.

Indian and African plate motions.. a Nature study.

Abstract:Mantle plumes are thought to play an important part in the Earth’s tectonics, yet it has been difficult to isolate the effect that plumes have on plate motions. Here we analyse the plate motions involved in two apparently disparate events—the unusually rapid motion of India between 67 and 52 million years ago and a contemporaneous, transitory slowing of Africa’s motion—and show that the events are coupled, with the common element being the position of the Indian and African plates relative to the location of the Réunion plume head. The synchroneity of these events suggests that they were both driven by the force of the Réunion plume head. The recognition of this plume force has substantial tectonic implications: the speed-up and slowdown of India, the possible cessation of convergence between Africa and Eurasia in the Palaeocene epoch and the enigmatic bends of the fracture zones on the Southwest Indian Ridge can all be attributed to the Réunion plume.

BBC News – Common medicines for elderly linked to death

BBC News – Common medicines for elderly linked to death.

Commonly used drugs – for conditions such as heart disease, depression and allergies – have been linked to a greater risk of death and declining brain function by UK researchers.

They said half of people over 65 were prescribed these drugs.

The effect was greatest in patients taking multiple courses of medication, according to the study in the Journal of the American Geriatrics Society.

Experts said patients must not panic or stop taking their medicines.

The researchers were investigating medicines which affect a chemical in the brain – acetylcholine. The neurotransmitter is vital for passing messages from nerve cell to nerve cell, but many common drugs interfere with it as a side effect.

Quantum Entanglement

Quantum Entanglement Could Stretch Across Time | Wired Science | Wired.com.

In the weird world of quantum physics, two linked particles can share a single fate, even when they’re miles apart.

Now, two physicists have mathematically described how this spooky effect, called entanglement, could also bind particles across time.

If their proposal can be tested, it could help process information in quantum computers and test physicists’ basic understanding of the universe.

“You can send your quantum state into the future without traversing the middle time,” said quantum physicist S. Jay Olson of Australia’s University of Queensland, lead author of the new study.

In ordinary entanglement, two particles (usually electrons or photons) are so intimately bound that they share one quantum state — spin, momentum and a host of other variables — between them. One particle always “knows” what the other is doing. Make a measurement on one member of an entangled pair, and the other changes immediately.

Physicists have figured out how to use entanglement to encrypt messages in uncrackable codes and build ultrafast computers. Entanglement can also help transmit encyclopedias’ worth of information from one place to another using only a few atoms, a protocol called quantum teleportation.

In a new paper posted on the physics preprint website arXiv.org, Olson and Queensland colleague Timothy Ralph perform the math to show how these same tricks can send quantum messages not only from place to place, but from the past to the future.
