Special thanks to Dr. Stephen Spicklemire,, Associate Professor of Physics at the University of Indianapolis. Dr. Spicklemire created this calculator and all of the underlying equations (functions) to help his astronomy students.
"vCalc is awesome for my astronomy students. With vCalc I can give them real problems that would normally require fairly sophisticated reasoning and mathematics, and now they can do the reasoning, because they’re not daunted by the math. It’s great." Dr. Steve Spicklemire
