Quantum Hall effect Updated 2025-07-16
Quantum version of the Hall effect.
As you increase the magnetic field, you can see the Hall resistance increase, but it does so in discrete steps.
Gotta understand this because the name sounds cool. Maybe also because it is used to define the fucking ampere in the 2019 redefinition of the SI base units.
At least the experiment description itself is easy to understand. The hard part is the physical theory behind.
The effect can be separated into two modes:
- Integer quantum Hall effect: easier to explain from first principles
- Fractional quantum Hall effect: harder to explain from first principles
- Fractional quantum Hall effect for : 1998 Nobel Prize in Physics
- Fractional quantum Hall effect for : one of the most important unsolved physics problems as of 2023

Particular attributes the ideal Chinese scholar would have include:It is in a sense sad (or awesome) that the computer has essentially replaced, or one may argue, enhanced beyong recognition, all of the traditional four arts, to the point that Ciro can't touch anything that is not a computer. Sometimes the old arts live on particularly closely though, e.g. in computer music, computer graphics and computer Go.
- mastery of the Four arts, which also implies the Four Treasures of the Study for caligraphy and painting

One is reminded of Nick Leeson.
One things must be said: the root cause of all of this is the replication crisis.
This is why he managed to go on for so long.

For synthesized streams like but it does not seem to accept multiple fails with:

sine=frequency=500[a];
sine=frequency=1000[b];

'-i for some reason. So is there a way to open a file from some filter? E.g.:ffplay -i tmp.wav -i tmp.mkv -filter_complex "[0:a]atrim=end=2[a];[1:v]trim=end=2[v]" -map '[a]' -map '[v]'Argument 'tmp.mkv' provided as input filename, but 'tmp.wav' was already specified. Epoch times Updated 2025-07-16

These are the final equations that you derive from the Lagrangian via the Euler-Lagrange equation which specify how the system evolves with time.

Erase SSD securely Updated 2025-07-16
You can't just shred individual sSD files because SSD writes only at large granularities, so hardware/drivers have to copy stuff around all the time to compact it. This means that leftover copies are left around everywhere.
What you can do however is to erase the entire thing with vendor support, which most hardware has support for. On hardware encrypted disks, you can even just erase the keys:
