“Don’t tell me it’s impossible; tell me you can’t do it. Tell me it’s never been done… the only things we really know are Maxwell’s equations, the three laws of Newton, the two postulates of relativity, and the periodic table. That’s all we know that’s true. All the rest are man’s laws.” – Dean Kamen, inventor of the Segway and recipient of the National Medal of Technology and Lemelson-MIT Prize.
This quote really struck me. It really got me wondering if this is true? I presume he is talking of Physics and Chemistry. Is everything else, except these things he mentions, we know theories we ourselves have developed with our own experience and thought?
