MWhat do we mean by "meaning" if not the relation of ideas?
-
MFor example, that expression of kinetic energy is the one that shows up in (non-relativistic) energy conservation laws. That expression...
-
MThere are reasons why we define things the way we do. Trying to understand those reasons is not a fools errand, but in fact a major...
-
MI could perfectly well define ##H:=\frac{5}{3}m^2v^3## and indeed I'm pretty sure I can prove some "theorems" about this, but who cares?
-
MYes. I actually ran into my conceptual problem with Taylor's example, because I always blindly applied the definition of work as a dot...

MMike_bb replied to the thread Undergrad Work and line integrals.I don't agree with this approach. I can say that by definition 2*2=5. There is always a reason why this or that thing has meaning...
-
MMike_bb replied to the thread Undergrad Work and line integrals.You can't understand why work is dot product of force and displacement, right?
-
MThank you for your detailed explanation. This is not even new to me, I have done it like this myself before. My question was actually...

Like.
Discussion around whether numbers or math exists is in the domain of philosophy of math. The issue also involves the definitional point... -

MMike_bb reacted to Sagittarius A-Star's post in the thread Undergrad Problem in understanding how upwards acceleration works (General Relativity) with
Agree.
No. Both, plus calculating to solve problems, are needed for successful lerning. -
MMike_bb replied to the thread Undergrad Problem in understanding how upwards acceleration works (General Relativity).Dale, Reading the textbooks is good practice but communication with scientists is the best practice. :smile: Mind ignites mind...

MMike_bb reacted to Dale's post in the thread Undergrad Problem in understanding how upwards acceleration works (General Relativity) with Agree.
I am glad. I think that I should recommend that you begin studying physics from a good textbook. So far, asking AI and asking us seems...
