In those cases, it can be useful to talk about the "Hall resistance" defined as:So note that it is not a "regular resistance", it just has the same dimensions, and is more usefully understood as a proportionality constant for the voltage given an input current:
This notion can be useful because everything else being equal, if we increase the current , then also increases proportionally, making this a way to talk about the voltage in a current independent manner.
And this is particularly the case for the quantum Hall effect, where is constant for wide ranges of applied magnetic field and TODO presumably the height can be made to a single molecular layer with chemical vapor deposition of the like, and if therefore fixed.
Ciro Santilli's birthplace!
Ciro Santilli lived in Santos from about the year 1998 to 2007, with a 10 month hiatus in Coventry, UK, until he went to the University of São Paulo.
Santos is the nearest beach city to São Paulo City, and for this reason:
- the largest port of Latin America in 2018, through which large chunks of the precious coffee export exited Brazil in the 19th century. There is a Coffee museum in Santos.This importance is also linked to the fact that Santos is one of the oldest european cities in Brazil, being founded in 1546. From this you can infer that it was a good port. One reason for this is obvious if you look at the map of the city: the neighbouring towns of Praia Grande and Guarujá form a large protected bay where ships may safely dock.
- a popular local tourist destination that gets crowded on hot weekends, with the beach line being fully built with tall buildings from the 60's, many of which became incredibly bent due to the inadequate technology used on such soft soil
Ciro idolizes Santos as the perfect location to live nature-wise due to its amazing wide sandy beach, in which Ciro spent endless hours walking on the sand and on the largest beachfront garden in the world (archive), meditating, and playing some soccer after school was over. Santos is also the city where Pelé first played professionally.
Ciro has visited Santos several times after leaving Brazil. Doing this gives him a weird feeling of having a separate life, in which time passes 2 weeks every few years. Of course, as your family grows, it gets harder and harder to go back home, and your family members might want to just go travel to more interesting places than just stay at your wonderful beach which you love in part due to nostalgia.
Ciro is also fond of the concept of the small public buildings near the beach garden (postos de praia), which serve different cultural activities: library, comic book store, art cinema, surf school. It is such a shame that the library and comic book ones are in such bad shape as of 2020, old books and poor people who go there to sleep a bit in the barely working air conditioning. Ciro fantasizes how those could instead be cultural hubs for the gathering of the brightest artists, and scientists, of town. Maybe they are just too small. Maybe it is not within the realm of possibility of public service. Maybe, we should focus instead in the poorer regions, far form the beach. But the dream remains.
Santos only has one natural defect: mosquitoes. By the sea it is fine because the wind is strong, and they don't like salt water. But anywhere else, you will be eaten alive, and maybe get dengue, Ciro got it once. Gene drive, please.
It runs along quiet roads, rather than a mixture of roads and tracks like the National Cycle Network, making it more appropriate for road bikes.
TODO interactive online app? Ahh, those charities that try to make money by individual transactions... when they die, nothing will be left of all their work.
Edit: noticed that it is on by default on OpenStreetMaps web UI under the "Cycle Map" layer marked at "NB".
No open signup it seems. TODO CV of owner.
They are making a proof assistant to integrate into the website: github.com/bookofproofs/fpl/, reminds Ciro Santilli of website front-end for a mathematical formal proof system.
But for infinity, things are messier, e.g. the size of the real numbers is strictly larger than the size of the integers as shown by Cantor's diagonal argument, which is kind of what justifies a fancier word "cardinality" to distinguish it from the more normal word "size".
The key idea is to compare set sizes with bijections.
The Scanning Electron Microscope by MaterialsScience2000 (2014)
Source. Shows operation of the microscope really well. Seems too easy, there must have been some extra setup before however. Impressed by how fast the image update, it is basically instantaneous. Produced by Prof. Dr.-Ing. Rainer Schwab from the Karlsruhe University of Applied Sciences.Mosquito Eye Scanning Electron Microscope Zoom by Mathew Tizard (2005)
Source. Video description mentions is a composite video. Why can't you do it in one shot?Is the only atom that has a closed form solution, which allows for very good predictions, and gives awesome intuition about the orbitals in general.
It is arguably the most important solution of the Schrodinger equation.
In particular, it predicts:
- the major spectral line of the hydrogen atom by taking the difference between energy levels
The explicit solution can be written in terms of spherical harmonics.
Some usage examples under: Section "Sequelize example".
As of 2021, this library is extremely painful to use. It does feel semi-mature, but there are just too much horrible things going on;
- the documentation is a bit messy and misses a lot of stuff. The examples are often too short, and it is hard to understand what specific options they are talking about do because they lack clear input/expected output pairs. Examples:
- the implementation has several inelegant/unintuitive annoyances/requirements of code repetition that drive you mad.The association API feels notably bad, it took a few days for Ciro Santilli to learn to do what he considers "basic" association operations, knowledge which he dumped to: stackoverflow.com/questions/22958683/how-to-implement-many-to-many-association-in-sequelize/67973948#67973948See also: how to decide if an ORM is good?.
- bugs are piling up. It appears that many key devs left, and current maintainers are just not being able to keep up.
Some glaring issues are listed at the horrors of Sequelize.
