I woke with a sudden thought that was so boring I went back to sleep to forget about it. It was something like this thread...

Let me put it this way, if you could have shown Michelson a laser and offered to sell it to him, how much do you think he'd be willing to pay?

He'd have charged it to the US Navy, they'd have to evaluate it. They funded his experiments anyway.

How expensive do you imagine a laser was in Michelson's day?

There was no market. Lasers were not a commodity item back then. They were vanishingly rare. If you had a previously-undiscovered painting by Da Vinci, how much would it sell for? Whatever the second-most avid buyer could afford, right? Like that. If you have the only laser in the world and nobody knows how to make more, how much is it worth? |
