That is a ridiculously pessimistic view. -
weirdoguy replied to the thread Rethinking Physics Education.To the contrary, you were quite unique :smile: A lot of students "know" that, yes, but really knowing and realizing, well that's a...

Thank you guys so much for your time and effort

weirdoguy replied to the thread I Sun gravitational lensing forces.And it is well known, that newtonian gravity gives wrong predictions in this context.

weirdoguy reacted to A.T.'s post in the thread B The work done by two objects on each other with
Love.
Avoiding confusion by being less explicit about what you mean? Is this a joke? -
A way of checking this which I found interesting was with systems of linear equations and trying to understand why, how, adding a...

The Jupiter is very well known and data about Jupiter is easily found . The Sun radiation will act on “thin” side of mirror (“upwards”)...

weirdoguy replied to the thread B Conflict between the conservation of matter and the rapid expansion of our universe.I don't care what AI says, and I'm not gonna discuss with it (and for your interest - it's talking about something different than you...

weirdoguy replied to the thread Rethinking Physics Education.I see a lot of steps here. Which one do you want to consider? And if you treat all of it as one step, then I don't really think that you...

weirdoguy replied to the thread Rethinking Physics Education.Which one? Besides, I don't think that every single mathematic manipulation has physical meaning. Again, what's the physical meaning of...

Well-intentioned but unrealistic. This article encapsulates what I gathered after more than 40 years of teaching university-level...

weirdoguy reacted to Orodruin's post in the thread Writing a vector parallel and normal to a unit vector ##\hat n## with
Like.
I actually think ##\vec A - (\vec A \cdot \hat n)\hat n## is nicer than the double cross product. It also generalises to any dimension. -
weirdoguy reacted to hmparticle9's post in the thread The flux through a cylinder from a charge at the origin with Like.
From looking at a diagram, the only component we need to worry about is the component of the flux in the ##z##-direction. The other...

weirdoguy replied to the thread Rethinking Physics Education.In the context of relativity it's a big waste of time. Your students have to understand that they need to rebuild their intuitions. And...

Hold on a moment. Who is "forcing" them? You are in control of how you teach them what and when. If you suspect that the subject...
