Submission + - To Launch a Nuclear Strike, Donald Trump Would Follow These Steps (bloomberg.com) 3

bsharma writes: How much power does the president alone have to launch a nuclear strike? Bloomberg News asked Bruce G. Blair, a former Minuteman missile-launch officer and research scholar at Princeton University’s Program on Science and Global Security, to spell out the step-by-step procedure.

The commander-in-chief’s power is clear: He or she has sole authority to use nuclear weapons.

Submission + - North Korea Says It Might Fire Missiles Into Waters Near Guam (nytimes.com)

bsharma writes: North Korea said Thursday that it was drawing up plans to launch four intermediate-range ballistic missiles into waters near Guam in the Western Pacific to teach President Trump a lesson, after the president warned of “fire and fury” against the North if it persisted in threatening the United States.

If the North were to follow through on its threat to launch an “enveloping strike” in the vicinity of Guam, it would be the first time that a North Korean missile landed so close to an American territory. The North’s official Korean Central News Agency reported that, according to the plan, four of the country’s Hwasong-12 intermediate-range ballistic missiles would fly over the three southern Japanese prefectures of Shimane, Hiroshima and Koichi before hitting the ocean about 19 to 25 miles from the coast of Guam.

Submission + - Hearing loss of US diplomats in Cuba is blamed on covert device (bostonglobe.com)

bsharma writes: The two-year-old U.S. diplomatic relationship with Cuba was roiled Wednesday by what U.S. officials say was a string of bizarre incidents that left a group of American diplomats in Havana with severe hearing loss attributed to a covert sonic device.

In the fall of 2016, a series of U.S. diplomats began suffering unexplained losses of hearing, according to officials with knowledge of the investigation into the case. Several of the diplomats were recent arrivals at the embassy, which reopened in 2015 as part of former President Barack Obama’s reestablishment of diplomatic relations with Cuba.

Some of the diplomats’ symptoms were so severe that they were forced to cancel their tours early and return to the United States, officials said. After months of investigation, U.S. officials concluded that the diplomats had been exposed to an advanced device that operated outside the range of audible sound and had been deployed either inside or outside their residences. It was not immediately clear if the device was a weapon used in a deliberate attack, or had some other purpose.

bsharma writes: August 21st will bring a history-making opportunity for the entire United States. On that day, every person in the country, including Hawaii and Alaska, will have an opportunity to witness at least a partial solar eclipse as the moon moves in front of the Sun. If you have the good fortune to be along the path of totality, stretching from Oregon to South Carolina, you will get to witness one of the most awe-inspiring views in nature – the wispy wonders of the solar corona.

Submission + - Scientists photograph BIRTH OF TIME with dark matter camera (express.co.uk)

bsharma writes: SCIENTISTS have pictured the moment the lights came on in the universe – effectively the dawn of recordable time. For the first 300,000 years after the Big Bang the rapidly expanding universe was dark and filled with neutral hydrogen gas doing nothing much.

But over the next half billion years the first stars and galaxies arrive through a process known as re-ionization – turning the lights on in the universe.

Submission + - Apple ordered to pay $506 million to university in patent dispute (reuters.com)

bsharma writes: A U.S. judge on Monday ordered Apple Inc to pay $506 million for infringing on a patent owned by the University of Wisconsin-Madison's patent licensing arm, more than doubling the damages initially imposed on Apple by a jury.

Wisconsin Alumni Research Foundation sued Apple in 2014, alleging processors found in some versions of the iPhone infringe on a patent describing a "predictor circuit," which improves processor performance by predicting what instructions a user will give the system. University of Wisconsin computer science professor Gurindar Sohi and three of his students obtained the patent in 1998.

Studying them is part of course in "Theory of Computation" taught in Computer Science. https://en.wikipedia.org/wiki/... Interestingly, even with "infinitely" fast machines, there will still be problems that may not be computable. https://en.wikipedia.org/wiki/...

There is a possibility that we may discover new forms (phases) of matter. For example study of Bose-Einstein condensate ( https://en.wikipedia.org/wiki/... ) has revealed a lot of new physics. Study of once similarly obscure Superconductivity has given rise to a lot of new physics. Imagine if Hydrogen metallization experiment would lead to a new method to cause nuclear fusion. It may also help to answer the fundamental question: What is matter? and Why does it exist?
