Laplace's equation Updated 2025-07-16
TODO confirm: does the solution of the heat equation always converge to the solution of the Laplace equation as time tends to infinity?
In one dimension, the Laplace equation is boring as it is just a straight line since the second derivative must be 0. That also matches our intuition of the limit solution of the heat equation.

Largey Brage Updated 2025-07-16
Both of them attended Montessori education at some point. Interesting! Mentioned in a talk by Sergey and highlighted at The Google Story.
They stepped down from leading Google roles in 2019: www.npr.org/2019/12/03/784570156/google-founders-brin-page-step-down-pichai-takes-over-as-alphabet-ceo
As The Google Story puts it about Largey:Ciro Santilli likes that.
Scholarship was not just emphasized in their homes; it was treasured.

Bessel function Updated 2025-07-16
Shows up when trying to solve 2D wave equation on a circular domain in polar coordinates with separation of variables, where we have to decompose the initial condition in termes of a fourier-Bessel series, exactly like the Fourier series appears when solving the wave equation in linear coordinates.
For the same fundamental reasons, also appears when calculating the Schrödinger equation solution for the hydrogen atom.

Caesium standard Updated 2025-07-16
Uses the frequency of the hyperfine structure of caesium-133 ground state, i.e spin up vs spin down of its valence electron , to define the second.
International System of Units definition of the second since 1967, because this is what atomic clocks use.
TODO why does this have more energy than the hyperfine split of the hydrogen line given that it is further from the nucleus?

Can't get you out of my head by Adam Curtis (2021) Updated 2025-07-16
Ciro Santilli was touched by this, and then watched several other documentaries by Curtis.
Notably the part of the governments have lost all power to companies, and can't do anything meaningful anymore to actually represent the people, because globalization reduces the power of governments.

How to reference a book in Wikipedia markup? Updated 2025-07-16
Their reference markup is incredibly overengineered, convoluted, and underdocumented, it is unbelivable!
Use the reference:
This is a fact.{{sfn|Schweber|1994|p=487}}Define the reference:
===Sources===
{{refbegin|2|indent=yes}}
*{{Cite book|author-link=Silvan S. Schweber |title=QED and the Men Who Made It: Dyson, Feynman, Schwinger, and Tomonaga|last=Schweber|first=Silvan S.|location=Princeton|publisher=University Press|year=1994 |isbn=978-0-691-03327-3 |url=https://archive.org/details/qedmenwhomadeitd0000schw/page/492 |url-access=registration}}
{{refend}}sfn is magic and matches the the author last name and date from the Cite, it is documented at: en.wikipedia.org/wiki/Template:SfnUnforutunately, if there are multiple duplicate
Cites inline in the article, it will complain that there are multiple definitions, and you have to first factor out the article by replacing all those existing Cite with sfn, and keeping just one Cite at the bottom. What a pain...You can also link to a specific page of the book, e.g. if it is a book is on Internet Archive Open Library with:
{{sfn|Murray|1997|p=[https://archive.org/details/supermenstory00murr/page/86 86]}}For multiple pages should use
pp= instead of p=. Does not seem to make much difference on the rendered output besides showing p. vs pp., but so be it:{{sfn|Murray|1997|pp=[https://archive.org/details/supermenstory00murr/page/86 86-87]}} Ciro Santilli Myers-Briggs Type Indicator Updated 2025-07-16
