Why it takes several days to enter inflammatory phase in COVID-19? Updated +Created
Why is it there such a clear separation of phases?
Why do people with mild symptoms go on to die? It is a great mystery.
Ciro Santilli's theory is that COVID is extremely effective at avoiding immune response. Then, in people where this is effective, things reach a point where there is so much virus, that the body notices and moves on to take a more drastic approach. This is compatible with the virus killing older people more, as they have weaker immunes systems. This is however incompatible with the fact that people don't seem to be contagious after the viral phase is over...

Kondo effect Updated +Created
If you adda bit of impurities to certain materials, at low temperatures of a few Kelvin their resistivity actually starts increasing if you go below a certain critical temperature.

Synthetic geometry of the real projective plane Updated +Created
It good to think about how Euclid's postulates look like in the real projective plane:
Unlike the real projective line which is homotopic to the circle, the real projective plane is not homotopic to the sphere.
The topological difference bewteen the sphere and the real projective space is that for the sphere all those points in the x-y circle are identified to a single point.
One more generalized argument of this is the classification of closed surfaces, in which the real projective plane is a sphere with a hole cut and one Möbius strip glued in.
Telephone-based system Updated +Created
This section is about telecommunication systems that are based on top of telephone lines.
Telephone lines were ubiquitous from early on, and many technologies used them to send data, including much after regular phone calls became obsolete with VoIP.
These market forces tended to eventually crush non-telephone-based systems such as telex. Maybe in that case it was just that the name sounded like a thing of the 50's. But still. Dead.

Television series that Ciro Santilli watched all episodes of Updated +Created
The best way to watch a television series is: wait for the thing to end. Then watch the first and last episodes of each season. The rest is fluff. And then pick up any missing interesting clips from YouTube. If a series holds you more than those episodes, it is one of the few amazing ones!
Ten ancient famous songs of China Updated +Created
This is a good place to start your journey, though it misses a lot, and some songs are not as memorable as others, there is huge variability in that list.

Brexit Updated +Created
There are valid reasons to be pro-Brexit, given the uselessness of the European Union.
The problem was how the campaign was conducted, in a purely nationalistic, populist and fake news manner, and largely supported by business leaders who immediately after still wanted to hire cheap foreign labour, use tax havens and move headquarters to other countries, e.g.:
