nasa takes inspiration from sports

By -


Apparently, NASA (USA's Space Agency) is studying the aerodynamics involved in sports balls moving through the air in order to make a spacecraft take the most efficient route to Mars. "Sports provide a great opportunity to our researchers to study aerodynamics with something they can relate to", says Rabi Mehta, chief of the Experimental Aero-Physics Branch of NASA's Ames Research Centre. Mehta gave a couple of examples to demonstrate his point - "A smooth golf ball travels half the distance a dimpled one travels, because the dimples delay separation of the ball from the boundary layer" and "When a quarterback throws the football he ideally wants to throw a tight spiral with high rotation rate to help stabilise the ball as it flies through the air".

At this rate, NASA might well field a couple of teams in the sports leagues and win them easily.

re-writeable paper ?

  Heard of re-writeable CD or drives , ever heard of re-writeable paper ?                            Printing has come a long way since the computer landed on the desktop. First,there were daisy-wheel printers, then dot-matrix printers, then inkjet and laser printers . The problem with all of these output devices, of course, is that they require paper -- lots of it -- and expensive consumables, like toner. Why can't someone invent an inkless, tonerless printer that allows the operator to reuse paper? As it turns out, this isn't a new idea. Xerox has been working with so-called electronic paper since the 1970s. Its most promising solution is a type of paper called "Gyricon." A Gyricon sheet is a thin layer of transparent plastic containing millions of small oil-filled cavities. A two-colored bead is free to rotate inside each cavity. When a printer applies a voltage to the surface of the sheet, the beads rotate to present one colored side to the

5 smartphones that have the best battery life

As they say, life with a smartphone is like having a second brain in your pocket. However, there are times when this second brain goes dead because of something as trivial as your phone running out of battery.  With most buyers focusing on phones with bigger displays and faster and more power-hungry processors, the humble battery pack that actually brings all the magic to life is often forgotten. But having said that, a big battery on a low spec, or worse a badly designed phone is also of no use. So here's our list of phones that not just offer great battery life but also come with best specs (well, almost).   Moto E4 Plus Kicking things off is the recently launched Moto E4 Plus which brings with it a massive 5000 mAh battery pack, a 5.5-inch 720p display, a fingerprint sensor running on Android 7.1.1. It's also equipped with a capable MediaTek MT 6737 quad-core processor clocking at 1.3GHz paired with 3GB RAM. There's also 32GB of inbuilt storage which can be exp
