🇨🇦🇺🇸 Physicist ⚡️and Eng. Physicist. Authority cannot justify itself. My arguments stand on their own merits: PhD mentioned only for “ad verecundiam” fools.
"Science is the organized skepticism in the reliability of expert opinion." -- R.P. Feynman "Cargo cult science is the organized support of expert opinion." -- Me Know what you are looking at.
Let’s try this again. @grok, can you prove this expression is true analytically? If you can’t, can the full featured Grok 4 do it?

Jeremy Brett without question. But I still like Basil Rathbone.
Who played Sherlock Holmes the best between these two? Basil Rathbone or Jeremy Brett #PollsterPulse #Actors #SherlockHolmes
He was not entirely ordinary, but it is true that innate potential matched with keen interests and hard work results in people with remarkable accomplishments.

They can't bring net order to the universe -- it must be compensated because ∆S>0. This office may be a direct result of success in mathematics.
Mathematicians: mathematics brings order to the universe. Also mathematicians:

When we use “theory” in the sciences, we mean something with a lot of evidence backing it up, like conservation laws, or the theory of relativity. Its foundations and limitations are well understood. Colloquially, it means something as flimsy as a wild guess, to a working…

If these are your lecture students, what would be the topic of your lecture? ✍️
And to use a colorful expression, AI can’t fart higher than its ass.
No. But the appearance of Wendy O. Williams and the Plasmatics with John Candy as Gil Fisher hosting The Fishin' Musician was groundbreaking.
This was BIG.
July 20, 1969. “Contact light, engine stop.” The Apollo 11 lunar module Eagle touched down at Tranquility Base on the Moon. A few hours later, Neil Armstrong and I stepped foot on the Moon, with Michael Collins orbiting close-by. An achievement resulting from years of…
Seems correct, but there are many mathematically beautiful theories that do not match reality; e.g., Hermann Weyl’s early attempt to unify E&M and gravity. Beautiful, but not our reality.
