EnglishMuffin,
Thank you about that note about Dr. Lardner. I wasn't aware of that. I have assumed that physics and engineering have come a long way since the book was written, and I think some of the information is wrong.
Are you sure Lardner said that these things were impossible? There is a simlar story about an aerodynamicist "proving" that bumblebees cannot fly. The story is at best, an inaccurate description of what he actually worked out.
