“The stuff that people are doing here is the future.”
-+Geoffrey Hinton, Google Distinguished Researcher

At Google, Neural Networks are behind much of the cutting-edge research in Machine Intelligence that enables speech recognition, computer vision, machine translation and more. Check out an article by the +Toronto Star, which highlights some of the history and promise of Deep Learning, and how it is finding ways into applications used by millions.
Artificial intelligence research using neural networks has taken off, with a $400-million boost from Google, in part thanks to Canadian Geoffrey Hinton.

For what we need artificial intelligence? For creating "more intelligent" spam-profiles to Google-plus?

Okay Google, you win.

Chief Executives of web giant Google have issued a statement warning that if the company is forced to pay tax they’ll in turn force the Australian people to use the terrible search engine Bing.   The company is believed to have paid only $74 million dollars on $2 billion dollars in projected earnings but has said that they’re entirely willing to pay tax provided the Australian people are entirely comfortable “getting on Altavista or finding where...

Einstein's Zurich Notebook
The Zurich notebook, held by the Albert Einstein Archives at the Hebrew University of Jerusalem, represents an almost complete testimony of Einstein's thinking in an intermediate phase of the emergence of General Relativity, beginning in mid-1912 and ending in early 1913.

In the center of his thinking as it is documented by the notebook was the problem of combining the available physical knowledge on gravitation with a generalization of the mathematical formalism of Minkowski's four-dimensional spacetime, with the aim to create a relativistic theory of gravitation which makes sense from a physical point of view and which corresponds, at the same time, to a consistent mathematical framework.

The principal challenge which Einstein faced consisted in constructing a field equation which, on the one hand, satisfies the requirements resulting from his ambitious program of formulating a theory of gravitation generalizing the principle of relativity, and which, on the other hand, can be reduced by an appropriate specialization to the familiar Newtonian law of gravitation. The history of Einstein's search for such an equation can, on the background of the Zurich notebook, essentially be written as that of a mutual adaptation between mathematical formalism and physical meaning.   
    
This notebook, handwritten by Einstein and found after his death, has been put online for anyone to read.

Give it a try here:

New type of gravitational wave detector proposed
The existence of gravitational waves is one of the central predictions of Einstein’s theory of general relativity. Gravitational waves have never been directly observed, though the indirect evidence is so good that Marc Kamionkowski, a theorist at Johns Hop...

Only two nations still refuse to ratify the UN Convention on the Rights of the Child: South Sudan and the United States.

America is working hard to improve the number of homeless children: "For every two homeless children in 2006, there are now three."

Here's how huge accumulation of private wealth helps to reduce child poverty: https://www.solveforx.com/search/moonshots
The callousness of America's political and business leaders is shocking once you start looking at the numbers.

The US is one of only two UN countries that has not ratified the convention. It has signed the convention. South Sudan recently passed a bill to ratify the convention.

Either way the US does not comply with the convention because it prohibits execution or life sentences without parole for under 18s.

But aside from those details, the figures in the actual article are truly shocking.

A very interesting project.

Philipp Emanuel Weidmann scanned OEIS sequences without a "formula" field using the Sequencer system [1] in order to identify new closed-form expressions for the sequence terms.

Recently Weidmann announced on the seqfan list that the search has now finished and that the results are available at [2].

A129254 and A218564 don't look good: the recurrences found surely describe the subsequences where the primes in question are just 2 and 3, respectively just 5, not the sequence for all primes.

Atheists are being hacked to death in Bangladesh, and soon there will be none left

"...these attacks are the methodical work of vigilante extremists working through a list of atheist bloggers. The list was drawn up last year when 100,000 protesters called on the government to introduce the death penalty for blasphemy."
“Words cannot be killed”. This is the Facebook cover page of Bangladeshi blogger Washiqur Rahman. It's a statement of solidarity with Avijit Roy, the Bangladeshi-American atheist blogger who was murdered last month in the capital of Dhaka by religious extremists.
