Real-time polymerase chain reaction Updated 2025-07-16
Also known as: Quantitative PCR (qPCR).
Like PCR, but the amplification machine measures the concentration of DNA at each step.
This describes one possible concentration detection method with fluorescent molecules that only become fluorescent when the DNA is double stranded (SYBR Green)

This allows you to predict the exact initial concentration by extrapolating the exponential curve backwards.
TODO: vs non-real-time PCR. Why can't you just divide by 2 for every heating step to reach back the original concentration? Likely the reaction reach saturation at an unknown step.
TODO: vs non-real-time PCR in medical diagnostics: do you really need to know concentration for diagnostics? Isn't it enough to know if the virus is present or not?
In "practice" it is likely "useless", because the functions that it can integrate that Riemann can't are just too funky to appear in practice :-)
Its value is much more indirect and subtle, as in "it serves as a solid basis of quantum mechanics" due to the definition of Hilbert spaces.
Full range achieved, going from fastest to slowest works (downshift), but going from slowest to next slowest (upshift) fails. Limits are good, B-tension screw didn't help
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.

We can get a list of the ordinals at: archive.org/details/bitcoin-ordinal-inscriptions.csv and then sort them by payload size with:
sort -k6 -n -t, ordinals.csv -o ordinals-sort-size.csv
This shows to us that as of block ~831k, there are 4 ordinals which are far far larger than any other between 3 MiB and 4 MiB, at about 10x larger than then 5th one d115a6e689086fd587e5032f24ba2a8c01f2f87cba758c9d5eb8cf7f6e9a816a
In those cases, a single inscription takes almost the entire block, and the inscribers must have had direct dealings with their mining pool:
As of 2024, all of the big ones were made in early 2023, so it seems that the trend has died down a bit.
