Requiem for a Dream (Lux Aeterna)

Ending a half-century of geological speculation, scientists have finally seen the process that causes rocks to move atop Racetrack Playa, a desert lake bed in the mountains above Death Valley, California. Researchers watched a pond freeze atop the playa, then break apart into sheets of ice that — blown by wind — shoved rocks across the lake bed.   …   By the end of the winter, the farthest-moving rock had travelled 224 metres.

Neutrinos from the Sun were detected when they crossed the Borexino detector’s ‘inner vessel’, a nylon sphere 8.5 metres across filled with purified benzene.

After decades of searching, physicists have finally confirmed the existence of low-energy neutrinos that are direct evidence for the first crucial step in the nuclear reaction that makes the Sun shine. While the detection validates well-established stellar fusion theory, future, more sensitive versions of the experiment could look for deviations from the theory that would reveal new physics.

The conversion of hydrogen into helium is the source of 99% of the Sun’s energy. The multistep process begins when the star’s hot, dense core squeezes two protons together to form deuterium, a heavy isotope of hydrogen with a nucleus made of one proton and one neutron. One of the fused protons then transforms into a neutron, a process that releases a neutrino and a positron (the antimatter counterpart of the electron).

While the positrons are almost instantly annihilated in collisions with electrons, the neutrinos zip through matter unscathed, so they escape straight into outer space, radiating in all directions at nearly the speed of light. Other nuclear reactions in the Sun also produce neutrinos, and 100 billion of the particles bombard each square centimetre of Earth every second. The proton–proton reaction accounts for 90% of all solar neutrinos, but the neutrinos it emits have relatively low energy, and their signal can be swamped by the radioactive decay of ordinary terrestrial materials. Thus, although more-energetic solar neutrinos have been detected since the 1960s, those from the proton–proton reaction had eluded detection so far.

…nuclear-power plants, which run at about 90% of capacity, avoid almost four times as much CO{-2} per unit of capacity as do wind turbines, which run at about 25%; they avoid six times as much as solar arrays do. If you assume a carbon price of $50 a tonne—way over most actual prices—nuclear energy avoids over $400,000-worth of carbon emissions per megawatt (MW) of capacity, compared with only $69,500 for solar and $107,000 for wind.   Updated information to August 22 [2014]:   …new figures reduce the benefits of the other technologies and improves the efficiency of renewables. But it does not alter the ranking: gas CC, nuclear and hydropower are still more cost effective at cutting emissions than wind and solar. And the gap between them and the others is still fairly large. 

 

The emerging technologies hype cycle, 2014*   …   Rather than leave things to chance, all the big industrial countries [and companies] nowadays have legions of engineers and scientists scanning the literature for ideas that portend blockbuster innovations capable of carving out new markets. Meanwhile, social networking has made it easier than ever for money and talent to join forces in order to hustle the innovation process along. In addition, today’s far broader channels of communication ensure that any new way of doing things becomes instantly known to everyone interested.

Helmet Mounted Video Camera   …developed by the National Institute for Occupational Safety and Health (NIOSH) for personal sampling of respirable dust. This method uses a video camera worn by the mine worker to provide a visual record of the worker’s activities concurrently with data collected by an appropriate datalogging exposure monitor also worn by the worker.  (Office of Mine Safety and Health Research, 2013)

Trinidad

A History of Freaque Waves:  “There Be Dragons”   …   1498: While on his third voyage on August 4, 1498, Columbus’ fleet of six ships was en-route along the southern tip of Trinidad to the Gulf of Paria when Columbus heard a fearsome roaring from behind his flagship. He turned to see a rogue wave as high as the ship’s masts that was approaching too fast for the fleet to escape. It lifted the vessels; hoisting them higher than anything the Admiral had ever experienced and then dropped the fleet into a huge trough. But it didn’t stop the ships. Once the wave was behind them, the flotilla escaped the constricted passage to get to the Gulf. Columbus named the passageway »Mouth of the Serpent.«  (Source: http://ycaol.com/demons_of_the_deep2.htm)

History of the World in Two Minutes  (Joe Bush)   …   “Hold onto your seat, don’t blink your eyes for a second!  Seventeen year old Joe Bush got a high school assignment to make a video reproduction. He chose history as a theme and tucked it all into two minutes.  He took pictures from the internet, added the track Mind Heist by Zack Hemsey (from the movie Inception) and then you get something like this.  Hold on tight!”
