I love that book. The "Fixing radios by thinking" part is a great insight on how Feynman developed such powerful intuition around physics at an early age. In contrast, modern electronics are not as transparent and intuitive as their vacuum tube counterparts. I wonder what would have happened if Feynman had to fix radios with transistors or integrated circuits.
