How are the bands measured experimentally?
Why are there gaps? Why aren't bands infinite? What determines the width of gaps?

The bald confident chilled out particle physics guy from Stanford University!
Also one can't stop thinking abot Leonard Hofstadter from The Big Bang Theory upoen hearing his name.
Some people call it "operating System".
The main parts of those systems are:
- sending multiple signals at very precise times to the system
- reading out some quantum error correction bits and sending error correcting signals back in a control loop
Ciro Santilli defines a "business film" as a film about business, enterprises or entrepreneurship. Political thrillers are closed related as well.
This is one of his favorite film genres!

This example is the same as nodejs/sequelize/raw/parallel_select_and_update.js, but going through Sequelize rather than with Sequelize raw queries.
NONE is not supported for now to not have a transaction at all because lazy.The examples illustrates: stackoverflow.com/questions/55452441/for-share-and-for-update-statements-in-sequelize
Sample invocation:where:
node --unhandled-rejections=strict ./parallel_select_and_update.js p 10 100 READ_COMMITTED UPDATEREAD_COMMITTED: one of the keys documented at: sequelize.org/master/class/lib/transaction.js~Transaction.html which correspond to the standard sQL isolation levels. It not given, don't set one, defaulting to the database's/sequelize's default level.UPDATE: one of the keys documented at: sequelize.org/master/class/lib/transaction.js~Transaction.html#static-get-LOCK. Update generates aSELECT FOR UPDATEin PostgreSQL for example. If not given, don't use anyFOR xxxexplicit locking.
Other examples:
node --unhandled-rejections=strict ./parallel_select_and_update.js p 10 100 READ_COMMITTED UPDATE
Then, the outcome is exactly as described at: nodejs/sequelize/raw/parallel_select_and_update.js:
READ_COMMITTED: failsREAD_COMMITTED UPDATE: works- This case also illustrates Sequelize transaction retries, since in this transaction isolation level transactions may fail:
Similar to quantum supremacy, but add the goal that the computation must be useful, i.e. make money or solve some open mathematical problem, Ciro Santilli's wife was quite excited about the possibility of finding some counter examples in number theory with quantum computers.
But now people want to send voice. How to do it?
It would not be practical without modulation: Why can't you send voice without modulation?
DokuWiki about physics, mostly/fully written by Jakob Schwichtenberg and therefore focusing on particle physics, although registration might be open to all.
Single chemical element, single phase (usually solid), but different 3D structures.
Whenever Ciro Santilli walks in front of a school and sees the tall gates it makes him sad. Maybe 8 year olds need gates. But do we need to protect 15 year olds like that? Students should be going out to see the world, both good and evil not hiding from it! We should instead be guiding them to the world. But instead, we are locking them up in brainwashing centers.
Video "The Purpose of Education by Noam Chomsky (2012)" puts it well, education can be either be:He has spoken about that infinitely, e.g. from when he was thin: www.youtube.com/watch?v=JVqMAlgAnlo
- a brainwashing to make people comply with The Establishment
- a way to get people genuinely interested and help them to reach their life goals

A discrete 2D game on a rectangular grid: towardsdatascience.com/reinforcement-learning-implement-grid-world-from-scratch-c5963765ebff
This is analogous to many traditional board games such as chess, the concept is very natural and maps well into computer.
The downsides of gridworld games are:
- it is hard to model speed in discrete worlds. When you 10x faster, when do you collide with something else that is also crossing your path?
- they tend to not use vector representations of objects. So to have an object be 10x longer than another one, the naive implementation has to add 10 smaller objects. This becomes untenable as the number of objects increases.
