    Op Amp Circuit Dilemmas: Diodes, Current, and Resistors Explained

    Not sure of your basic electronic knowledge, but there is Ohm's Law and the same law for diodes. For diodes, you want a resistor in series with the power source that will drop all the supplied voltage with the exception of the forward voltage drop of the diode. Since you do not have the data...

    I Energy Emission from Black Holes: Exploring the Mystery

    My understanding is that once light or anything else crosses the event horizon, it will not re-emerge. However, we detect high energy beams of radiation coming from opposite sides of some of the celestial bodies that I have been told are types of black holes. Obviously I'm missing something here.

    I Theory of Relativity: Light, Mass & Gravitational Lensing

    Thank you for this answer. Obviously, My high school understanding of physics from back in the 70's is way outdated. I have been reading every science magazine I could find for 50 years and I have not gained as much as I thought I did. Time to go back to the basics.

    I Theory of Relativity: Light, Mass & Gravitational Lensing

    If light is pure energy, then how can gravitational lensing work? And if light has some mass, how can it change directions instantly when it is traveling through a prism? My high school science teacher had no answer 45 years ago.
