Looking for sci-fi novel, 1st book I read in 70's that got me hooked. It was from the pulp era, 40's or 50's? Man discovers the power of his mind can create a spaceship from nothing, and create armor for it from concentrated photons. I believe he ended up in space somehow with some of his college friends, and the excitement starts. I think it was written by one of the masters of sci-fi when he was just starting out.
