This is almost certainly detailed paper that the one pager A New Method of Measuring Nuclear Magnetic Moment promises at the end, they mention:and reference A New Method of Measuring Nuclear Magnetic Moment.
In two letters to this journal, we reported briefly on a new precision method of measuring nuclear moment, and on some results. In this paper we shall give a more detailed account of the method, apparatus and results.

This is the paper that contains the first successful report of experimental nuclear magnetic moment observation.
They promise more at the end:and this promise was fulfilled on the later The Molecular Beam Resonance Method for Measuring Nuclear Magnetic Moments.
We have tried this experiment with LiC1 and observed the resonance peaks of Li and Cl. The effects are very striking and the resonances sharp (Fig. 1). A full account of this experiment, together with the values of the nuclear moments, will be published when the homogeneous field is recalibrated.
This figure sums it all up: they were measuring the intensity of one side of a molecular beam after a Stern-Gerlach experiment.
Then, they vary the constant magnetic field before the splitting, and at the same time apply a fixed radio frequency to the beam.
When the constant magnetic field makes the energy gap match the radio frequency input, nuclear spin of many atoms goes to the anti-aligned direction, the beam gets diverted, so the previously detected beam gets weaker.

Ciro Santilli 34 Updated 2024-12-15 +Created 2024-11-15The goal of our broken educational system is not to teach.
It is simply a test of who can learn the most in the least amount of time.
What is being learnt is of little importance. it doesn't matter if it is useful or beautiful things.
The useless exams are set exactly at a difficulty level that produces a Normal distribution of grades:The difficulty is just set for your particular group of students.
- too hard and everyone gets 0, so you can't split people well
- too easy and everyone gets 100, so you can't split them well either
Molecular beams are cool because they create a one dimensional flow of molecules, which makes it easier to observe certain single-molecule effects, as it removes the multi-particle issues from experiments.
Key molecular beam experiments include:
- Stern-Gerlach experiment, which confirmed the existence of spin
- Rabi's NMR experiment, which confirmed the existence of nuclear spin
The center piece of the control system of atomic clocks is a molecular beam.
School must offer free accommodation for students by Ciro Santilli 34 Updated 2024-12-15 +Created 2024-11-15
Ciro Santilli 34 Updated 2024-12-15 +Created 2024-11-15More precisely, for students whose parents don't live near the school. Or alternatively, online-only courses that offer the same diploma as the presencial version. Or a compromise where the best N% students get accommodation, where N is a parameter of how decent your society is overall.
Since all the learning resources will be available online on OurBigBook.com, or through online 1-to-1 chats with mentors, it might be cheaper for students to work either from their parent's homes if their home has reasonable work conditions: a silent room with reasonable Internet access and no drug addicts in the house.
Alternatively, a public local library with free WiFi would do as well. But there would need to be a strict silence policy enforced, unlike most public libraries we see today. Ciro once saw a bird shaped noise detector that would sing if the noise went above a certain threshold, that was a good idea. Just like linting, it is easier to let machines decide deterministically on subjective questions to reduce useless arguments over who is right. Ciro has even seen libraries where the local council uses the same library open space as a citizen counsel area. What's the fucking point... these people have never done any deep work in their lives.
Then the state only needs to pay transportation and temporary accommodation to attend concentrated month-long laboratory workshop courses and week-long conferences, since the only reason for universities to exist should be the laboratories. In cases where the home conditions are not good enough, the state can either pay for on-demand WeWork-like offices near the student's home, of for a full on-campus accommodation as in a boarding school. What is indispensable is that all students who pass the entry criteria must have such working conditions. Students who stay home can also earn a scholarship to help pay for their rent, food and Internet access.
Anything else is just incredibly unfair to the poor. Ciro Santilli has already witnessed two cases, in developed, and under-developed countries, where very high potential poorer students were forced to work to support themselves in parallel to a demanding degree because their parents couldn't pay their rent on a different city, and the students mental health issues due to this. In one of those cases the student had to abandon the course altogether.
It doesn't help that school has become a pure student-evaluation system, which basically implies putting studets through a lot of useless pressure.
One of the stories that Ciro Santilli's father tells is about how when they were dating, one of Ciro Santilli's mother's greatest wish for her hypotetical child would be that "they should not need to work during their studies as she had". As destiny would have it, Ciro Santilli's family had good conditions and Ciro never thought even once about money. And even then, school still sucked. Imagine without that basic, mandatory, stability!

Ciro Santilli 34 Updated 2024-12-15 +Created 2024-11-09This should come as no surprise, as to be come successful, you have to do something different than the masses, and often take irrational risks that make you worse off on average.
Some mentions:
- in episode 5 "The Partner" of The Playlist, an awesome 20222 Netflix series about the history of Spotify, a hypothetical Peter Thiel diagnozes Spotify co-founder Martin Lorentzon with ADHD, and mentions that a large number of rich people are neurodiverse, 30% in the tech industry as opposed to 5% in the general population
