BLACK HOLE MYSTERY DATING BACK 40 YEARS SOLVED BY "BEST EVER" SIMULATION  A team of astrophysicists from Northwestern University, Oxford University, and the University of Amsterdam, used graphical processing units to crunch large sets of data and simulate how black holes interact with their accretion disks. The first photo of a black hole was captured in APRIL this YEAR PARIS: Scientists on Thursday unveiled the most detailed simulation of a black hole yet, solving a mystery dating back more than four decades over how the star-devouring monsters consume matter Coming fresh on the heels of the first ever photo of one of the giant objects, which are scattered across the Universe, astrophysicists are now several steps closer to understanding how they form and develop.

Small Parts / Electronic Components of Mobile Phone and Their  Function                               The PCB of a mobile cell phone has several small parts or electronic components. When LEARNING MOBILE REPAIRING , it is important to learn and understand how to identity these small parts or electronic components and understand their function. Identification of these small parts on the PCB OF MOBILE PHONE is easy if you know and understand some of the basic rules. It is also important to understand what to do if any of these small components is faulty. Most of these electronic components are SMD  ( SURFACE MOUNT DEVICES) They don’t have any leads like thru-hole ELECTRONIC COMPONENTS .                                                            ...
