Ciro Santilli's sinophily Updated +Created
Two things come to mind when Ciro Santilli thinks about his sinohpilia.
There is a strong "Ciro Santilli's knowledge hoarding" side to it. Ciro has decided that he has to know EVERYTHING about China. It's culture. It's people. It's art. And so once that has been decided, it becomes inevitable.
But of course, there is also the "which part of Ciro's inner being led to that hoarding decision" part of things. Mishima's quote often comes to mind:
Every night I return to my desk precisely at midnight. I thoroughly analyze why I am attracted to a particular theme. I drag it into my conscious mind. I boil it into abstraction.
Exoticism is undoubtedly part of it.
Maybe it has something to do with growing up observing 5th+ generation Japanese Brazilians immigrants, well, being Asians and crushing it academically. But also being quiet people, and sometimes misfits. I.e., nerds.
Maybe there is also someting to do with the influence Japanese anime, highly popular during Ciro's hildhood in Brazil. Ciro, unlike many of his friends, left that relatively early, as he got into the deeper pleasures of natural sciences and then more traditional Asian culture. But still.
Largey Brage Updated +Created
The outcome of Larry Page and Sergey Brin performing a Dragon Ball fusion dance.
Both of them attended Montessori education at some point. Interesting! Mentioned in a talk by Sergey and highlighted at The Google Story.
But in 2023 they were somewhat pulled back in by the AI race and competition with ChatGPT.[ref]
As The Google Story puts it about Largey:
Scholarship was not just emphasized in their homes; it was treasured.
Ciro Santilli likes that.
Galilean invariance Updated +Created
A law of physics is Galilean invariant if the same formula works both when you are standing still on land, or when you are on a boat moving at constant velocity.
For example, if we were describing the movement of a point particle, the exact same formulas that predict the evolution of must also predict , even though of course both of those will have different values.
It would be extremely unsatisfactory if the formulas of the laws of physics did not obey Galilean invariance. Especially if you remember that Earth is travelling extremelly fast relative to the Sun. If there was no such invariance, that would mean for example that the laws of physics would be different in other planets that are moving at different speeds. That would be a strong sign that our laws of physics are not complete.
The consequence/cause of that is that you cannot know if you are moving at a constant speed or not.
Lorentz invariance generalizes Galilean invariance to also account for special relativity, in which a more complicated invariant that also takes into account different times observed in different inertial frames of reference is also taken into account. But the fundamental desire for the Lorentz invariance of the laws of physics remains the same.

Time-independent Schrödinger equation Updated +Created
The time-independent Schrödinger equation is a variant of the Schrödinger equation defined as:
Equation 1.
Time-independent Schrodinger equation
.
So we see that for any Schrödinger equation, which is fully defined by the Hamiltonian , there is a corresponding time-independent Schrödinger equation, which is also uniquely defined by the same Hamiltonian.
The cool thing about the Time-independent Schrödinger equation is that we can always reduce solving the full Schrödinger equation to solving this slightly simpler time-independent version, as described at: Section "Solving the Schrodinger equation with the time-independent Schrödinger equation".
Because this method is fully general, and it simplifies the initial time-dependent problem to a time independent one, it is the approach that we will always take when solving the Schrodinger equation, see e.g. quantum harmonic oscillator.
