Paper cut: Can a saw made out of paper slice through wood?

By Ultron -
Paper always seemed like the wimpiest player in Rock, Paper, Scissors. Sure, it's easy to imagine a heavy rock crushing a pair of scissors, and we all know that scissors can cut paper. But how does paper win simply by covering rock?





Paper proves itself a lot tougher than it looks in a new video from carpenter John Heisz of the I Build It website and YouTube channel. In the simple two-minute video, Heisz uses one sheet of regular white printer paper to cut out a round saw-blade shape, and inserts it in his saw.
It seems like the thin piece of paper can't possibly cut anything, but he builds up slowly, testing the blade on paper, then cardboard, then finally moving on to a small piece of wood, which it slices through easily.
Don't get too excited, paper pushers. When Heisz tries a thicker cut of wood, the paper blade chugs maybe halfway through before crumpling up against the wooden surface and surrendering in a torn heap of dead tree.



"While this really doesn't have any practical applications, it was interesting to do," he writes on his site. "Even more so, since the paper I used was nothing out of the ordinary -- just regular printer paper with no special treatment. Add to that the time of year (it was hot and humid, making the paper fairly limp with moisture), it's amazing that it worked at all."
He gave the paper-blade concept a shot at cutting a different surface, but it wasn't happening. "I did make another 'blade' to test it on a piece of aluminum, but it more or less just polished the edge before wearing out." he wrote. "The abrasiveness of the paper works well on wood, but is no match for anything harder."
Many YouTube viewer pointed out that the battle is kind of a Civil War, since paper and wood both come from trees. Still, it's a marvel to watch, and Heisz's video has earned nearly 2.5 million views after just one day -- and paper has earned some new fans. Wrote commenter Rom Jaikat, "Thank you, I now have a whole new level of respect for paper."

Warning: Hackers steal millions from ATMs using 'just their smartphones'

Cyber-robbers flee Taiwan with swag swiped from 'malware-infected machines' Authorities in Taiwan are trying to work out how hackers managed to trick a network of bank ATMs into spitting out millions. Police suspect that two Russian nationals wearing masks cashed out dozens of ATMs operated by Taiwan's First Bank on Sunday and left the country the following day. The crooks stole an estimatedT$70m ($2.2m) hours after a typhoon battered the region around Taipei, the Taiwanese capital. The two (or perhaps at least three) crooks behind the theft didn't use bank cards, judging from security camera footage. Instead, the cybercriminals appeared to gain control of the machines with a "connected device," possibly a smartphone, according to police. Targeted ATMs were made by German manufacturer Wincor Nixdorf, which admits some of its machines in Taiwan were hacked as part of a "premeditated attack." Three different (unspecified) strains of mal...

Well dear readers today we will take a look at what a processor is made up of and different components it contains and also we will decipher this technical mambo jumbo for you. This figure illustrates the innards of a typical generic processor or CPU as well all know. The thin wires are visible and connected to this main sort of a chip die. The center rectangle is the main  heart of our processor. The basic building block of any processor are transistors. Billions and Quadrillions of them. Microprocessors Processor Transistor count Date of introduction Quad-core + GPU AMD Trinity 1,303,000,000 2012 Quad-core z196 1,400,000,000 2010 Quad-core + GPU Core i7 Ivy Bridge 1,400,000,000 2012 Quad-core + GPU Core i7 Haswell 1,400,000,000 2014 How do we create processors? We take a raw silicone and then melt it to form an ingot.  Afterwards we spin this ingot to form a wafer which is thoroughly tested with lasers for its the precision in its sur...
