24:22 I really wish this interviewer had NOT interrupted Dr Giessibl and pressured him to rush through these slides,
because there were ESPECIALLY fascinating slides at 24:33 and onwards.

I still voted this video up for its amazing fundamental experimentation + research + technology!

17:35 — So the total charge density is not ring-like but the DFT calculations still gave the ring structure in force predictions (for some less or more understood reason).
Some resonance effects in overlap of partially occupied states perhaps?? That is: Is the humps maximum maybe approximately between two allowed standing electron wave wavelengths for a HOMO? But this is all metal and electron gas with no discrete levels at Fermi energy, so theres no HOMO right? Hmm …

21:05 — Superposition of two energy potentials forms an itermediate hump giving a second stable equilibrium-bonding-distance (physisorption) beyond the one with minial bond distance (chemisorption).
I wonder: What are these two potentials and the long distance repulsive part? What repulses something physisorbed when it is not pauli repulsion/degeneracypressue?

23:18 Nice. Here the inner actual pauli repulsion (chemisorption) actually shows up here (the "eyes" pupil). At the former cross sectional force vs distance&offset charts (18:08) this is cut off at the bottom.

So, besides math and science, I am heavily into politics. Is politics "right brain" or "left brain" activity?
(Answer: neither. There is on such BS as "left brain" or "right brain" activity)

Right out of the gate he repeats long-debunked "right vs left" brain myths and lies about "strengthening one part of the brain over another".
