Jeff has spoken a lot in public about Amazon, perhaps even more than other comparable founders, see e.g. Section "History of Amazon". Kudos for that.

Once you've done the Apache Jena CLI tools setup we can query all users with Full Name (FN) "John Smith" directly fom the rdf/vcard.ttl Turtle RDF file with the rdf/vcard.rq SPARQL query:and that outputs:

Jim Simons Updated 2025-07-16
Ciro Santilli's wife, who was frustrated with academia at some point, admires the fact that Simons managed to make infinite money, and then invested back in actual science, e.g. through the Simons Foundation.

Josephson effect Updated 2025-07-16
Discrete quantum effect observed in superconductors with a small insulating layer, a device known as a Josephson junction.
To understand the behaviour effect, it is important to look at the Josephson equations consider the following Josephson effect regimes separately:

Josephson voltage standard Updated 2025-07-16
The most practical/precise volt standard.
It motivated the definition of the ampere in the 2019 redefinition of the SI base units
The wiki page en.wikipedia.org/wiki/Josephson_voltage_standard contains amazing schematics of the device, apparently made by the US Government.

Julian Schwinger Updated 2025-07-16
He started working at night and sleeping during the moring/early afternoon while he was at university.
He was the type of guy that was so good that he didn't really have to follow the university rules very much. He would get into trouble for not following some stupid requirement, but he was so good that they would just let him get away with it.
Besides quantum electrodynamics, Julian worked on radar at the Rad Lab during World War II, unlike most other top physicists who went to Los Alamos Laboratory to work on the atomic bomb, and he made important contributions there on calculating the best shape of the parts and so on.
He was known for being very formal mathematically and sometimes hard to understand, in stark contrast to Feynman which was much more lose and understandable, especially after Freeman Dyson translated him to the masses.
However, QED and the men who made it: Dyson, Feynman, Schwinger, and Tomonaga by Silvan Schweber (1994) does emphacise that he was actually also very practical in the sense that he always aimed to obtain definite numbers out of his calculations, and that was not only the case for the Lamb shift.

This seems like a decent option, although it has bugs coming in and out all the time! Also it is quite hard to learn to use.
Shortucts:
- Shift + R: cut tracks at current point. You can then select fragments to move around or delete.
- Shift mouse click drag: select multiple clips: video.stackexchange.com/questions/21598/select-range-of-clips-in-kdenlive
Add subtitles:then drag on top of the video track. To add only to part of the video, cut it up first.
