Haha.
Oops. I had to go back and edit that post about 3 times because I kept making mistakes. Too early in the morning maybe? Oh well, what's... -

Like.
Why are we talking about human perception? Relativity worked just fine for the 13.69 billion years before humans came along. It's a... -
DaveE replied to the thread Undergrad Odd coincidence: two people with same name living on the same street.I suspect people named Kowalski are more common in the Chicago area than near San Diego, for example. Of course if it's just a math...

Yeah I’ve seen that documentary style stuff, it’s interesting but I’m still a bit skeptical about how much “language” is actually going...

DaveE reacted to Dale's post in the thread Undergrad Capacitor Voltages at t = 0: Zero or Split? with Like.
Yes. In other words there is no real-valued solution to the problem. I am not sure why you say “Norton” here. It is Kirchoff’s current...

DaveE replied to the thread Undergrad Capacitor Voltages at t = 0: Zero or Split?.Vc1 and Vc2 are initial conditions that have not been specified. You can't really say anything about them. You might choose to specify...

But do you fully understand that the addition of R changes the problem? In other words, everyone will agree about your solution to the...

DaveE replied to the thread Undergrad Capacitor Voltages at t = 0: Zero or Split?.The infinite current flows in an infinitely short time. So how much charge is diverted through R with a finite current in an infinitely...

DaveE replied to the thread Undergrad Why is a Gaussian function used to represent a wave packet?.Because when your only tool is a hammer, everything looks like a nail? It sure makes the math easier to model with gaussians.

DaveE reacted to berkeman's post in the thread Physics/math: how much knowledge does a high school teacher need? with Like.
I'm not sure I like the metaphor of "standing above their pupils", at least in a STEM teaching environment. I've tutored numerous folks...

DaveE reacted to PeterDonis's post in the thread Is the quantum wave function a real object or a mathematical tool? with Like.
Physics is not about opinions. Different QM interpretations say different, and mutually inconsistent, things about what the wave...

DaveE reacted to timmdeeg's post in the thread Is the quantum wave function a real object or a mathematical tool? with Like.
Whether or not the wave function real is in the sense of ontic is interpretation dependent.

DaveE reacted to renormalize's post in the thread Paradox in Induced Dipole Forces: Does it violate Newton's Third Law? with Like.
In Physics Forums you should use ## to wrap in-line LaTeX equations and $$ to wrap display equations. I've reformatted your post below...
