12:48 Could it be the 4 disks on the djed represent the four energy levels of orbiting electrons, the oval "head" of the Ankh the semi-closed eccentric magnetic or electric field line following the fall of an electron from highest orbit level, the Sun above representing the light (photon), etc..

2:15 I think i might have found something to work with in GeoGebra. Pharaoh's crook and flail? Earlier the image was available as google search result, it is now gone however in the meantime i downloaded the file it came from so i can do a screenshot (have to download it to see it). There are some interesting enunciations in the article too. "For the principle of conservation of energy to be hold true, it is necessary to add an extra term to the equation of motion as the radiation reaction force."

8:24 As for self induction of a single electron, it is very simple. Similar with self induction of a current made of many electrons eventually moving inside a conductor (self induction, the magnetic field created by a current generates back a current that opposes its cause).

However the problem gets more complicated and also more captivating when we consider a single accelerated electron moving in vacuum also on a curved trajectory which still fits the definition of an electric current. Then, we might have eccentric self induction and an electric momentum away from its cause which i call a virtual particle.

9:47 E=mc2 also means mass is energy. The photons which move at the speed of light only have mass in the sense they carry energy. However. Speed of light in glass is about 2/3 than in vacuum (BTW, way or infinitely outside of the scariest part of the Lorentz curve, or almost non-relativistic).

I understand the photons might be (instantly) slowed down when they enter glass. However. When light escapes glass it accelerates back to full c (c is always the same bla bla). Where do the slowed down photons get the extra energy to accelerate instantly back to c? (head scratching emoticon here).
