Adam Frank notices a critical breakdown around our expectation of flying cars: We’re masters of electromagnetism, not gravity. It’s fascinating to think about, actually. Our high tech world is based almost entirely on the electomagnetic force. The electron and photon are the basis of most technological progress in the last hundred years. Or, as Adam puts it: And the digital culture we’ve built rests directly on our ability to understand and manipulate electromagnetism’s quantum manifestations.
