Feynman's first wife, previously his local-high school-days darling. Feynman was like an reversed Stephen Hawking: he married his wife knowing that she had a serious illness, while Hawking's wife married him knowing that as well. Except that in Feynman's case, the disease outcome (tuberculosis) was much more uncertain, and she tragically died in 1945 much earlier while Feynman was at Los Alamos Laboratory, while Hawking, despite his decline, lived much longer.

Feynman first noticed Arline on the beaches on the region of his home in Far Rockaway, in the Queens, New York, near Long Beach. She lived a bit further inland in Cedarhurst. Arline was beautiful and boys competed for her, but Richard persisted, stalking her at an after-school social league sponsored by the local Synagogue and joining an art class she went to, until he eventually won it out. The region was highly Jewish, and both were from Jewish families, as also suggested by their family names.

Reading about her death e.g. at Genius: Richard Feynman and Modern Physics by James Gleick (1994) is a major tearjerker, it's just too horrible. The book mentions on chapter "The Last Springtime" that at last, during the last months of her life, after much hesitation, they did fuck in the sanatorium Arline where was staying at in Albuquerque, the nearest major city to Los Alamos (154 km), despite the risk of Feynman being infected, which would be particularly serious given that Feynman would be in constant contact with students and possibly infect others as part of his career as a researcher/teacher. Feynman would visit her on weekends by bus, and stay in Los Alamos during the week.

Arline finally died on June 16th 1945, exactly one month before the Trinity nuclear test was carried out. The atomic bombings of Hiroshima and Nagasaki were a little later on 6 and 9 of August 1945.

On one of his last trips to Oak Ridge town late 1945, after her death, Feynman walked past a shop window and saw a pretty dress. He thought to himself, "Arline would have liked that", and the reminder made him cry for the first time after Arline's death.

It is even sadder to think that the first antibiotics for tuberculosis, streptomycin, finished its first major clinical trial at around 1948, not long after her death.

Ciro Santilli considers this tragedy a cause of Feynman was a huge womanizer during a certain period of his life.

This is a good book.

It has some overlap with Surely You're Joking, Mr. Feynman, which it likely takes as primary sources of some stories.

However, while Surely goes into a lot of detail of each event, this book paints a more cohesive and global picture of things.

In terms of hard physics/mathematics, this book takes the approach of spending a few paragraphs in some chapters describing in high level terms some of the key ideas, which is a good compromise. It does sometime fall into the sin of to talk about something without giving the real name to not scare off the audience, but it does give a lot of names, notably it talks a lot about Lagrangian mechanics. And it goes into more details than Surely in any case.

In this chapter Richard Feynman talks about his experiences in Brazil.

"O Americano, Outra Vez!" means "The American, once again!" in Portuguese, which is what one of the samba school boss exclaimed when Feynman was not playing well his instrument, the frigideira, during a rehearsal.

Feynman really enjoyed Brazil's (and notably Rio's) stereotypical "take it easy and enjoy life" attitude.

Key quote that names the chapter:

Where Sylvain Poirier dumps his mathematics and physics brain.

Notably, given the domain name, it is clear that he likes formalization of mathematics-stuff, like Ciro Santilli.

At first glance, looks a bit dry though, not many examples.

As of my last knowledge update in October 2021, "Ten15" could refer to several different things, as it's not a widely recognized term on its own. It may refer to a brand, company, product, or initiative depending on the context. However, without additional information, it's difficult to provide a specific answer.

The dude was brutal. Ron Maimon praises that at youtu.be/ObXbKbpkSjQ?t=944 from Video "Ron Maimon interview with Jeff Meverson (2014)".

Signedness refers to the property of a data type that indicates whether it can represent both positive and negative values (signed) or only non-negative values (unsigned). This concept is important in computer science, particularly in programming and data representation. 1. **Signed Data Types**: A signed data type can represent both positive and negative numbers. For example, in many programming languages, an `int` (integer) type is typically signed by default.

"Presumed security" is a concept that refers to the assumption that certain systems, protocols, or environments are secure by default, often due to their design, reputation, or the ways in which they have been implemented. This presumption can lead users and organizations to believe that they do not need to take additional precautions or to scrutinize the security measures in place, potentially leading to vulnerabilities if the underlying assumptions turn out to be incorrect.

A Marsquake refers to seismic activity on the planet Mars, analogous to earthquakes on Earth. These quakes are detected and measured by instruments designed to capture vibrations in the Martian crust. NASA's InSight lander, which landed on Mars in late 2018, is equipped with a seismometer capable of detecting these seismic events.

Sednoid generally refers to a group of trans-Neptunian objects located in the outer region of the solar system, specifically in the distant area beyond Neptune. The term is primarily associated with a particular object known as 90377 Sedna, which was discovered in 2003. Sedna is notable for its highly elongated elliptical orbit, taking it far beyond the traditional boundaries of the solar system.

"Richard Robertson" could refer to multiple individuals depending on the context. Without additional details, it's challenging to provide a specific answer. Here are a few possibilities: 1. **Richard Robertson (Ice Hockey)**: A professional ice hockey player who has played in various leagues. 2. **Richard Robertson (Scottish Cricketer)**: An athlete known in the cricketing world.

**Earthquake**: An earthquake is a natural phenomenon characterized by the sudden shaking of the ground caused by the movement of tectonic plates. These movements can result from faults in the Earth's crust, volcanic activity, or other geological processes. Earthquakes can vary in magnitude, intensity, and duration, and they can lead to significant damage to buildings, infrastructure, and can result in loss of life.
