I see you implicitly assuming a radical opposition between being mathematical (accurate) and being described in words without equations. I disagree with the idea of such an opposition. Indeed some of the math needs equations hard to understand for the majority, but I still see possibilities to...

I also have a plan to redesign the math and physics curriculum. For this the way I found best was most often to just rewrite everything from scratch rather than collect external references, as in most cases I don't know good enough references compared to what I can make myself. My work remains...

Moreover, my contribution was NOT off-topic. There are many ideas in my speech that are on-topic. But you need to actually take the time to read or hear it to notice this.

Sorry but I see no legitimate right to pretend that I should shut up and let you conclude by such an awful and completely mad personal attack that you are making against me. I think I was clear about the problem. Not only my intelligence, my shyness, my natural temptation to respect and trust...

Yes absolutely I was forced. Especially by my mother, who behaved as a tyrant, under the influence of some authoritative voices around (teachers, etc). I'm very tired of all those people who can't believe that this could happen. As I wrote here :

I agree that, unfortunately, academic degrees are nonsense, and I'm very angry at people around who forced me to "study" up to PhD, following all that academic nonsense after I had already managed to rediscover a mathematical expression of General Relativity when I was 16. I just posted my...

I think you made the right guess at the end of your video already : it's the pixels, the dense periodic succession of vertical lines in the structure of the screen. You can find more detailed explanations in the wikipedia article "Diffraction grating". An interference from 2 slits, alternates...

I provide an answer this question in my page General Relativity : the Einstein field equation. I just wrote this page in the last days; see also the cosmology page linked there for a more intuitive, less formal description. This explanation is quite brief and assumes some familiarity with tensor...

It depends. Only if you have an explicitly finite family of nonempty sets, that you can list : E1,...En then you can use a proof whose length is proportional to n : Let x1 in E1, Let x2 in E2, ... Let xn in En then (x1,...,xn) is in the product, which is thus nonempty. But for the mathematical...

Why post links to articles that cannot be read online for free ? and the title does not sound like a consensual position. The concept of observation in QM indeed first appears as fuzzy and undefined. But it is only so as long as you keep applying the equations to a small isolated system. In...

According to John Baez's page of http://math.ucr.edu/home/baez/open.questions.html, I would describe things like this : QM does not predict anything like a preference for [either "horizontal" or "vertical"] polarization over diagonal polarization, because there is not such a thing as a...

If you look for a process that can produced entangled particles, a natural one is to take a pair of electrons and separate them passively in a spatial manner without using a magnetic field. Then their spins are entangled (opposite to each other in any direction of measurement). Still it is not...

Energy in GR can no more be described as a precise quantity simply obtained by integrating some explicit field along the space-like 3D surface we consider. This does not mean that there is no conservation of energy. But it takes a more subtle, complex form. In particular we can roughly define...

In my opinion the only reasonable interpretation is the "Mind makes collapse" interpretation. I explained this starting with introductions of metaphysics, noting that purely mathematical laws of physics can only describe a mathematical universe, with a merely mathematical existence. There...

I already answered this question in https://www.physicsforums.com/showthread.php?t=613451.
