“We don’t need to understand why a rainbow or fogbow or glassbow is formed in order to appreciate its beauty, of course, but understanding the physics of rainbows does give us a new set of eyes (I call this the beauty of knowledge).”
― Walter Lewin, For the Love of Physics

“Our poor ears can hear a pretty wide range of frequencies—more than three orders of magnitude, in fact—but we aren’t outfitted to hear the music of the heavenly spheres.”
― Walter Lewin, For the Love of Physics

“Genetic engineering is not really something new. Human beings have been fiddling with genes for as long as ten thousand years. That’s how long they have been growing plants and herding animals.”
― Isaac Asimov, The Roving Mind

“One way to think of architecture and construction engineering, then, is that they are the arts of battling the downward force to a standstill. We may think of certain feathery skyscrapers as having escaped gravity. They’ve done no such thing—they’ve taken the battle literally to new heights. If you think about it for a little while, you’ll see that the stalemate is only temporary. Building materials corrode, weaken, and decay, while the forces of our natural world are relentless. It’s only a matter of time.”
― Walter Lewin, For the Love of Physics
