Thank you for these excellent lectures. Much appreciated by this non-physicist.

Special Relativity is extremely intuitive. Anybody can figure it out all by themselves, and can do so while having no prior education in physics. All that is required is a simple, and thorough, step by step analysis of "Motion", via the use of nothing but the mind. The only problem is that this method is the simplest method possible. As a consequence, you end up independently understanding Special Relativity, along with independently having creating all of the SR equations, in just over an hour.

This simplicity and perfection of efficiency, embarrasses many physicists and professors, etc. Some folk just do not accept the fact that it can be done in such a manner. My Special Relativity playlist videos, 1 -> 9, show the simple step by step analysis of motion in the working. But few even bother to look at them.

However, this absolute understanding of Special Relativity, allows the mind to wrap around the entirety of Special Relativity, and thus in turn allows you to see it at work as a single image within the mind.
