Say Cheese, Black Hole!

Yes, we have it! The picture we all were waiting for. Powehi, the Black Hole, saying cheese! If you have watched the movie Interstellar, you can see similarities between the actual image and the one shown in the movie. Christopher Nolan put up a beautiful picture in our minds but the credit goes to Sir Albert Einstein. Sir Albert Einstein’s general relativity theory spoke about the presence of black holes.

SpaceX Has Shown its Commercial Might with Falcon Heavy Flight Mission

SpaceX has successfully launched its first-ever triple rocket landing during the Falcon Heavy flight mission for an advanced communications satellite into orbit for Arabsat. Launch itself has created significant buzz by recovering the rocket’s three Falcon 9 core stages. The Falcon Heavy currently holds 27 engines, which are distributed among three Falcon 9 core stages. The entire assembly was mounted on historic pad 39A at the Kennedy Space Center.

Ultra-low Impedance Testing Using the 2-Port Shunt-Through Measurement Technique

Measuring ultra-low impedances (20 micro-ohm) is a challenge for any power distribution network (PDN) design engineer. The 2-port shunt-through measurement is the standard method for measuring milliohm impedances up to very high frequencies (GHz). Unfortunately, this measurement includes an undesirable ground loop related to the instrument grounds and test setup cabling. The ground loop introduces significant errors if proper care is not taken. This application note shows how to measure as low as 20 μΩ using the Picotest J2102A as a ground loop breaker.
