A team at MIT has found a completely unexpected set of changes: Inside the tiniest of spaces — in carbon nanotubes whose inner dimensions are not much bigger than a few water molecules — water can freeze solid even at high temperatures that would normally set it boiling. The discovery illustrates how even very familiar …
The Carnival of Space 486 is up at Stylish Stem Cassini spacecraft prepares for incredible ‘Ring-Grazing Orbits’ at Saturn Cassini will be flying just past the edge of Saturn’s main rings. These close passes by the rings are called “Ring-Grazing Orbits,” during which Cassini will come within 90,000 kilometres (56,000 miles) of Saturn itself. Cassini …
The members of the North Atlantic Treaty Organization (NATO) pledged in 2014 to increase their defense spending to 2 percent of their gross domestic products by 2024 During the campaign, President elect Trump indicated that he would only support NATO only if NATO countries met their commitments. Mr. Trump raised alarm during the election campaign …
Arxiv – A physically inspired model of Dip d792 and d1519 of the Kepler light curve seen at KIC8462852, by Eduard Heindl1 , Furtwangen University, Germany The star KIC 8462852 shows a very unusual and hard to comprehend light curve. The dip d7922 absorbs 16% of the starlight. The light curve is unusually smooth but …
Bjorn Lomborg calculated using the best peer-reviewed economic models show the cost of the Paris promises – through slower gross domestic product growth from higher energy costs — would reach $1 trillion to $2 trillion every year from 2030. U.S. vows alone — to cut greenhouse-gas emissions 26 percent to 28 percent below 2005 levels …
Coal power is a major producer of global warming emissions Hoping that countries like China, India and Russia will act against their self-interest will not work. It is better to develop realistic solutions, like cleaning up coal. China’s first HTR-PM (pebble bed) reactor will be completed in late 2017 and generate 210 MWe. It is …
China’s HTR-PM (high temperature pebble bed nuclear reactor) project is squarely aimed at being a cost-effective solution that will virtually eliminate air pollution and CO2 production from selected units of China’s large installed base of modern 600 MWe supercritical coal plants. It is a deployment program with the first of a kind commercial demonstration approaching …
Here is a link to a 16 page unclassified Summary of A Threat to America’s Global Vigilance, Reach, and Power High-speed maneuvering weapons The U.S. lead in the technologies of high-speed flight is in question, particularly as it pertains to military applications. Several countries around the world have been quite busy establishing their own capabilities, …
China and Russia have deployed anti-satellite capability. Russia has deployed what could be multiple kamikaze satellites such as “Kosmos 2499” — designed to sidle up to American satellites and then, if ordered, disable or destroy them. A technical adviser at the Secure World Foundation, which is a nonprofit organization dedicated to space sustainability, pointed out …
OPEC struck a long-sought agreement to reduce production by 1.2 million barrels a day. Both U.S. and international crude futures are trading north of $50 a barrel. West Texas Intermediate, the U.S. benchmark, is up $1.27, or 2.57%, at $50.71. Brent crude, the global benchmark, is up $1.41, or 2.72%, at $53.25 a barrel. The …
Cognitive Scientist Joscha Bach was asked what ingredients of human-level artificial intelligence we seem to be missing, and how to improve AI forecasts more generally. Before we can implement human-level artificial intelligence (HLAI), we need to understand both mental representations and the overall architecture of a mind There are around 12-200 regularities like backpropagation that …
