Ha ha. Funny. But could it really work? What would it take to make a flying Tesla that converts from driving to flying mode with the thrust coming out of the wheels? Time for some physics. I can think ...

Visiting all the children on Earth in one night requires serious horsepower (or, reindeerpower?) and now we know exactly how much. According to research carried out by undergraduates at the University ...

To calculate the force on a wire carrying a current at right angles to a magnetic field, use the equation: force on a conductor carrying a current = magnetic field strength × current × length A 50 cm ...
