Dale replied to the thread Is A.I. more than the sum of its parts?.There are ongoing debates on this topic both in psychology (how much of what we think is a conscious decision is actually a... -
Dale replied to the thread Is A.I. more than the sum of its parts?.We don’t know if humans have agency. We have trouble defining and reliably measuring intelligence in humans. One thing that I think is... -

Like.
I often see the use of the colloquial "meter" in the USA, while the scientific world uses the SI unit of length, the metre. -
Dale replied to the thread Undergrad Why is SI taught in US university physics courses instead of cgs?.That depends on what you are measuring. It reduces the zeroes for particle physics. What I really wonder is why people went from CGS... -
Dale replied to the thread Undergrad Why is SI taught in US university physics courses instead of cgs?.Yes. Ignoring the sizes of the base units, both systems have base units with dimensions of mass, length, and time. But cgs uses only... -
Dale replied to the thread Undergrad Small question about constantly accelerating charges.Not the reference frame. The proper acceleration of the antenna is what matters. Is the antenna inertial or co-accelerating. Yes -
Dale replied to the thread Undergrad Small question about constantly accelerating charges.The question is not particularly controversial if the person asking the question clarifies one specific point that is usually neglected... -
Dale replied to the thread Undergrad Why is SI taught in US university physics courses instead of cgs?.Maxwell's equations are different in SI vs CGS units. The best source for that is this table from Wikipedia... -
Dale reacted to jbriggs444's post in the thread Undergrad Why is thermal energy treated differently than other kinds of energy? with
Like.
No, that is not the frame that I implicitly chose. The table does move with respect to the table+book COM frame. The frame that I had... -

Haha.
We could discuss all that stuff over a Pint of Best! -
Dale replied to the thread Undergrad Why is SI taught in US university physics courses instead of cgs?.Most publications in most STEM fields require SI. There are exceptions, of course, and hybrid units. But most professional science uses SI. -

Like.
When Newton wrote about action and reaction he was referring to forces. It was the 1680's. The concept of energy, if it even existed at... -
Dale replied to the thread Undergrad Why is thermal energy treated differently than other kinds of energy?.That isn’t surprising given how poorly written your original post was. This one was much better These equations are incorrect. The...
