Facebook Users Can Now Play Games Like Pac-Man In Messenger

The social network giants wants to make messaging more intensive.















BENGALURU -- For users hooked on to Facebook's Messenger app, it's game on.
The social network on Tuesday rolled out a feature that allows users to play hugely popular games such as Pac-Man and Space Invaders, the company's latest attempt to get users spend more time on its messaging app. The new feature, initially rolled out in 30 countries with 17 games, will be available on the latest versions of iOS and Android operating systems. A user, in the midst of a conversation, can tap on a game controller icon to choose a game and start playing. The feature also allows user to challenge their friends for a game.
Facebook made Messenger a standalone app in 2014, a move that initially irked many users. The app, however, gained popularity after the company added a host of features to it. The social network has also added instant video and payment facilities to the app. Facebook boasts of having more than one billion…

Can You Spare A Zeptosecond? Scientists Have Just Measured The Shortest Unit Of Time Ever

It's a trillionth of a billionth of a second.


A millisecond is a thousandth of a second, and a nanosecond is a billionth of a second, but there’s another measurement of time that makes both of them look slow.  Scientists have for the first time been able to measure something in a zeptosecond, or a trillionth of a billionth of a second. Laser physicists in Munich fired an extreme ultraviolet light pulse onto a helium atom to excite the electrons, causing one to break free ― a process called photoemission. At the same time, they shot an infrared laser pulse to detect the electron as it left the atom. That’s when it happened.  “Depending on the exact electromagnetic field of this pulse at the time of detection, the electron was accelerated or decelerated,” the Technical University of Munich stated in a news release. “Through this change in speed, the physicists were able to measure photoemission with zeptosecond precision.” The experiments also allowed scientists to see how energy f…
