When I first started in PhysicsForums I used to just post links of articles I found interesting. Every time I got various messages... -

Agree.
Hm. It is almost the same question. Reporting to check with mods. -
WWernerQH replied to the thread Undergrad Unexpected findings in need of an explanation (retrograde motion of Mars).The ellipticity of the orbits is important. It just occurred to me that an asteroid with a very elliptic orbit, but a perihelion...

WWernerQH reacted to JimWhoKnew's post in the thread Undergrad The imaginary part of the wave function with Like.
Introductory textbooks usually deal a lot with time-independent Hamiltonians of the form$$H=\frac{\mathbf{P}^2}{2 m}+V(\mathbf{x})\quad...
