India's Fastest Train

Image
Gatimaan Express is India's first semi-high speed train that runs between Delhi and Jhansi. It operates at a maximum speed of 160 km/h (99 mph). The train takes 265 minutes to cover the 403 km (250 mi) journey from Hazrat Nizamuddin to Jhansi Junction railway stations with an average speed of 91.25 km/h. Operator: Northern Railway Engine: WAP 5 8 coaches are AC 1st Class while remaining 2 coaches are Executive chair car. In October 2014, the railways applied for safety certificate from Commission of Railway Safety to start the service.

World's Fastest Train

The L0 Series is a Japanese maglev train developed by the Central Japan Railway Company. This train holds the land speed record at 603 km/h (375 mph) This train will start it's commercial operation on the Tokyo and Osaka. The operational speed will be 505 km/h (314 mph) and it will take only 40 minutes to go from Tokyo to Nagoya.The  first section to Nagoya is expected to be ready by 2027 . On 16 April 2015, a manned seven-car L0 series trainset reached a speed of 590 km/h (370 mph), breaking the previous world record of 581 km/h (361 mph) set by a Japanese MLX01 maglev trainset in December 2003.  KEEP SUPPORTING US FRIENDS

A new type of transistor

SOLUTION FOR NEXT GENERATION NANOCHIPS COMES OUT OF THIN AIR.    Instead of sending electrical currents through silicon, it sends electrons through narrow air gaps, where they can travel unimpeded as if in space. The device eliminates the use of a semiconductor, making it faster and less prone to heating up.  “Every computer and phone has millions to billions of electronic transistors made from  silicon, but this technology is reaching its physical limits where the silicon atoms get in the way  of the current flow, limiting speed and causing heat,” lead author Shruti Nirantar said.  “ Our air  channel transistor technology has the current flowing through air, so there are no collisions to  slow it down and no resistance in the material to produce heat .”  The design solved a flaw in traditional solid channel transistors – they are packed with atoms, according to the team. This means electrons passing through them collide, sl...

Why Captcha has turned into checkboxes??

Image
A CAPTCHA is a type of challenge–response test used in computing to determine whether or not the user is human. The term was coined in 2003 by Luis von Ahn, Manuel Blum, Nicholas J. Hopper, and John Langford. The most common type of CAPTCHA was first invented in 1997 by two groups working in parallel But google bots are 96% accurate in decoding these Captchas So google introduced a new alternate to captcha. i.e,,Re-Captcha In 2017, Google improved this mechanism, calling it an "invisible reCAPTCHA". According to former Google "click fraud czar"  Shuman Ghosemajumder , this capability "creates a new sort of challenge that very advanced bots can still get around, but introduces a lot less friction to the legitimate human. That is the check box you find in some sites..!!
