Here’s Why You Should Never Stand Next To A Building Demolition

 

 

” There are few things finer than watching a building implode—even if it almost kills you.

  That seems to be the feeling shared by a couple who stood among the small crowd of observers during a demolition in the Czech Republic, anyway. As an old clothing factory collapses, a giant hunk of concrete comes bouncing past the non-existent safety perimeter and nearly takes their heads off when it hurtles by. Not that anyone’s too impressed. “

Early Mankind’s Secret Weapon For Slaying Mammoths? Dogs

” After hunting them for at least a million years, humans suddenly became really good at killing woolly mammoths, but modern humans haven’t been able to figure out just how they did it. A new theory suggests that, maybe, man’s best friend played an important role.

  In central Europe and north Asia, there are massive mammoth graveyards dating back to 44,000 years ago, with tens of thousands of mammoth bones, some arranged in geometric patterns and some arranged into huts, found with stone tools and evidence of people. There wasn’t however, any evidence of how they were killing the shaggy ancestors of today’s elephants.

  In an article titled “How do you kill 86 mammoths?,” Penn State anthropologist Pat Shipman theorizes that humans’ secret weapons may have been dogs.

  While combing through the literature about the mammoth megasites, Shipman found that none of the usual big-mammal slayers seemed like plausible explanations for a mass mammoth die-off.”

” In Berelekh – in the north of Siberia’s Sakha Republic – are more than 160 of the tusked goliaths.”

” ‘ One of the greatest puzzles about these sites is how such large numbers of mammoths could have been killed with the weapons available during that time,’ she said.

  Theories on such ‘mammoth megasites’ have included floods washing bones to a certain spot or herds that fell through thin ice. But they seem to date to 44,000 years ago, around the time modern humans emerged.

  She found that ‘few of the mortality patterns from these mammoth deaths matched either those from natural deaths among modern elephants killed by droughts or by culling operations with modern weapons that kill entire family herds of modern elephants at once’.

  The professor concluded in her research, outlined in Quaternary International, that the mammoths were killed in the same spot for many generations. ‘There’s something that’s drawing them to that location,’ she said.

  She believes the sites may have been on migration routes in spots where early humans and their domesticated dogs could attack.”

Biden’s Gavel Gaffe In Poland

 

 

” Vice President Joe Biden wandered a little off course on a trip down memory lane today.

“ Fifteen years ago, I was honored, as the chairman of the Foreign Relations Committee, to lead the fight for Poland’s admission into NATO,” Biden said in Warsaw during a visit designed to reassure America’s Eastern European allies in the wake of Russia’s move to take control of Crimea.

  The only problem: Biden wasn’t chairman back then.

  It was Sen. Jesse Helms, a North Carolina Republican, who guided the committee and launched the floor debate on granting NATO accession to Poland, Hungary and the Czech Republic. Biden did lead minority Democrats in approving the treaty resolution, after having initially expressed doubts about the political viability of expanding NATO.

“ If we are really going to alienate the Russians,” Biden asked in January 1997, according to New York Times columnist Thomas Friedman, “what are we going to get for it?” “

Lawrence Livermore Is Building The Most Powerful Super-Laser Ever

 

 

 

” Sometimes a laser’s quality and usefulness is measured in pure watts. In that respect, a new laser in production at Lawrence Livermore National Laboratories (LLNL) can certainly hold its own: at a full petawatt, otherwise known as one quadrillion watts, it’s powerful enough to drive the world’s most demanding experiments.

  Sometimes, though, you need a laser to be able to produce incredibly short bursts of light, and here it shines as well: each pulse from the laser lasts just 30 femtoseconds. At 10 Hz, it can fire these quadrillion watt bursts of light faster than an AK47.”

 

 

 

 

” The High Repetition Rate Advanced Petawatt Laser System (HAPLS) will be a major step forward for high-energy laser science, primarily because of that firing rate. A petawatt laser is not unheard of, since a watt is a measure of power over time — joules per second, to be precise. Thus, delivering more than 600 joules over a 450 femtoseconds (as LLNL’s previous petawatt laser can) is not all that different from delivering 30 joules over 30 femtoseconds. They’re both around a petawatt. However, with a firing rate of 10 per second, the overall output can be hundreds of times greater over longer periods (like a long, sluggish microsecond).”
