In the most massive test to date, physicists have probed a major paradox in quantum mechanics and found it still holds even for clouds of hundreds of atoms.Using two entangled Bose-Einstein condensates, each consisting of 700 atoms, a team of physicists co-led by Paolo Colciaghi and Yifan Li of the University of Basel in Switzerland has shown that the Einstein-Podolsky-Rosen (EPR) paradox scales up.The researchers say this has important implications for quantum metrology – the study of measuring things under quantum theory...One of the tools we use to close one of the gaps is quantum mechanics, a theory that arose...

Bubbles Red Arrow Five centuries ago, Leonardo da Vinci observed air bubbles deviating from a straight path in a zigzag or spiral motion. However, the cause of this periodic motion remained unknown until now. Researchers from the universities of Seville and Bristol have solved the mystery surrounding the unsteady path of an air bubble rising in water. Professors Miguel Ángel Herrada of the University of Seville and Jens G. Eggers of the University of Bristol have uncovered a mechanism that explains the erratic movement of bubbles rising in water. The findings, published in the prestigious journal Proceedings of the National...

Then there are all the suggestions that the UFOs are optical illusions, meteorological phenomena or electromagnetic events The Silly Season has come early this year. Normally it happens in August, when wicked people all over the northern hemisphere temporarily stop doing evil things to take their children to the beach and enjoy the last of the summer. With no bad news to report, desperate journalists will run any story, however silly. Why is it Silly Season in June this year? Because the US Department of Defence has announced that it will release a report on 'Unidentified Aerial Phenomena' (UAPs), which...

“Classical dynamics says if you know the state of a system at a particular time, this can tell us the entire history of the system,” said Germain Tobar, a student in the School of Mathematics and Physics at the University of Queensland. “This has a wide range of applications, from allowing us to send rockets to other planets and modeling how fluids flow.” “For example, if I know the current position and velocity of an object falling under the force of gravity, I can calculate where it will be at any time.” “However, Einstein’s theory of general relativity predicts the...

President Trump said Thursday, “Twitter 'SHADOW BANNING' prominent Republicans. Not good," Trump tweeted. "We will look into this discriminatory and illegal practice at once! Many complaints.” Shadow banning, also known as ghost banning, is when a user and their content visibility is limited from the online viewers in a way that does not make it clear to the user that they have been banned. For example, Rep. Matt Gaetz, R-Fla., Mark Meadows, R-N.C., Rep. Jim Jordan, R-Ohio, and RNC Chairwoman Ronna McDaniel all failed to appear on Twitter’s autofill search box when users typed in their names, Vice News reported...

The 21st century is reminding of us of some uncomfortable truths. Abroad, recent controversies over the rise of Chinese mercantilism, the specter of Iranian and North Korean nuclear weapons, tensions in the European Union, the calcified Palestinian question, mass migrations, and the resurgence of Islamic terrorism all offer a number of lessons. At home, just as instructive is the strange juxtaposition between Obama’s suave progressivism and Trump’s coarse conservatism. Here are 10 takeaways from our current controversies. The Western world is in turmoil largely because of the widening gap between what the people see as true and the “truth” that...

The Associated Press is out with new polling pitting Democrat Hillary Clinton against Republican Donald Trump. Clinton beats Trump in every category among the general electorate, including on the questions of who is best to create jobs, who is better on international trade and who can "Make America Great Again," which of course is Trump's campaign slogan. First, the criteria:

Two big ideas often come up in discussions about the search for extraterrestrial intelligence, or SETI. One is the Drake Equation, which estimates the number of civilizations in our Galaxy whose signals we might be able to detect--potentially thousands, according to plausible estimates. The other is the so-called Fermi paradox, which claims that we should see intelligent aliens here if they exist anywhere, because they would inevitably colonize the Galaxy by star travel--and since we don't see any obvious signs of aliens here, searching for their signals is pointless. The Drake Equation is perfectly genuine: it was created by astronomer...

Stephen Hawking's New Black-Hole Paper, Translated: An Interview with Co-Author Andrew Strominger The Harvard string theorist explains the collaboration's long-awaited research on the black-hole information paradox Share on Facebook Share on Twitter Share on Reddit Email Print Share via Google+Stumble Upon Penrose diagram for a semiclassical evaporating black hole, as presented in "Soft Hair on Black Holes." CREDIT: Prahar Mitra In the mid 1970s, Stephen Hawking made a string of unnerving discoveries about black holes—that they could evaporate, even explode, and destroy all information about what had fallen in. Physicists spent the next 40 years sorting through the wreckage. Then last year, at a...

The Fermi Paradox By Tim Urban Facebook275k Twitter0 Google+0 Pinterest0 Everyone feels something when they’re in a really good starry place on a really good starry night and they look up and see this:Some people stick with the traditional, feeling struck by the epic beauty or blown away by the insane scale of the universe. Personally, I go for the old “existential meltdown followed by acting weird for the next half hour.” But everyone feels something.Physicist Enrico Fermi felt something too—”Where is everybody?”________________A really starry sky seems vast—but all we’re looking at is our very local neighborhood. On the very...

Mysteries and Paradoxes of Evangelization – A Meditation on a Passage from the Gospel of Mark By: Msgr. Charles PopeIn the Church throughout the world today, we are rightly more focused on evangelization. It is “job one,” and Jesus could not have been clearer: Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you (Matt 28:18-20).However, even as we become more serious and practical about effective ways of evangelization, we must also remember the...

Industry interest and activity in shale reservoirs continues to escalate. The big headline-makers, such as the Barnett, Haynesville, Marcellus, comprise only some chapters of the big story. The less familiar names also are beginning to make their mark. Count the Cane Creek shale in the Pennsylvanian-age Paradox formation in the Paradox Basin in southeast Utah among those receiving considerable attention. "The Cane Creek is a transgressive-regressive sequence in the lower portion of the Paradox," said AAPG member Stephanie Carney, geologist at the Utah Geological Survey (UGS). "It's tens of feet to nearly 200 feet thick, over-and underlain by salt beds,"...

Sun Paradox Challenges Old Earth Theory by Tim Clarey, Ph.D. * Scientists previously uncovered fossil algae in Archean rocks—evidence of life in a period that evolutionists date from 3.0 to 3.5 billion years ago.1 At that supposed time, the sun would have been 70 percent less luminous compared to today, making Earth's surface icy and uninhabitable. But if those rocks are truly 3.0 to 3.5 billion years old, the meager solar energy delivered by the younger sun at that time would have prevented algae or any other life form from growing. Attempting to come up with something to counter the...

(Phys.org) —Scientists as eminent as Stephen Hawking and Carl Sagan have long believed that humans will one day colonise the universe. But how easy would it be, why would we want to, and why haven't we seen any evidence of other life forms making their own bids for universal domination? A new paper by Dr Stuart Armstrong and Dr Anders Sandberg from Oxford University's Future of Humanity Institute (FHI) attempts to answer these questions. To be published in the August/September edition of the journal Acta Astronautica, the paper takes as its starting point the Fermi paradox – the discrepancy between...

Rick Perry says Texas is the most successful state in America. He's right. Texan economic output exceeds Mexico's and Australia's and rivals India's. Rick Perry has been governor of Texas for nearly 11 years. Does the logic of politics lead us to conclude that the governor of the nation's most successful state, ipso facto, is the best man to be president of the economically gasping United States? We are about to find out. Getting lost, however, among the governor's adventures in the lovely hamlets of New Hampshire is that Texas, with or without him, has a story the rest of...

One of the great oddities of the current job market is that job openings (as reported by the BLS) and help-wanted online ads (as reported by the Conference Board) have both been on the rise over the past year. These are usually signs of good labor demand.However, actual new hires and employment growth have only edged up mildly. In other words, good labor demand has not translated into actual hires.We can see this most clearly in the business and professional services sector (advertising, law, computer programming, etc). The chart below plots the rate of new hires against the rate...

Another probability “paradox”, the two-envelope problem1, goes like this: Before you are two envelopes, A and B. One of them contains $X and the other $2X (which is equivalent to $Y/2 and $Y). You pick one envelope and are (1) asked if you would like to keep it or switch, or (2) open it, view its contents, and then asked if you would like to keep it or switch. Which strategy, keeping or switching, is likeliest to win you the big bucks? No peeking solution The traditional paradoxical solution to (1) is to argue this. Suppose you pick A, which...

Mexican singer Sergio Vega was murdered while on a national tour at the weekend, just hours after denying reports of his death, local media reported. The 40-year-old singer, known as El Shaka, was driving his red Cadillac to a concert in the northern Mexican state of Sinaloa on Saturday when his car was intercepted by unidentified shooters in a truck, reports said. His murder came just hours after he told entertainment website La Oreja that online reports of his death were wrong. "It's happened to me for years now, someone tells a radio station or a newspaper I've been killed,...

Obama's surgeon general pick - a doctor who's supposed to be a health role model (if nothing else, I mean what the hell else does the Surgeon General do besides PSA's about 'do this, don't do that) and she's obese. It's more a statement about Obama than her, in reality. THis whole administration and the people working in it. Up is down. Good is bad. Left is right. 36,000 jobs saved/created for 1 trillion in stimulus tax money, but 3.3 million jobs lost since Obama took office. A tax cheat for Treasury Secretary. A huge pro-abort for Health and Human...
