Bertrand Russell: "Physics is mathematical not because we know so much about the physical world, but because we know so little."

Thank you. That's the one. I have quoted it on here a few times before now, with more accuracy on previous occasions I hasten to add.

PS. I believe it was the same geezer who gave us Russell's paradox

Are you thinking of some board other than the BABB, maybe? I didn't notice another time.

Definitely this one, and possibly on this thread, around about the time we discussed QM, albeit briefly. I tried a search but nothing came up. I am sure, nonetheless.

Ah, could be the search engine's fault. Wait until Monday.
