Seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth. It encompasses a range of topics, methodologies, and related concepts. Here is a list of key elements associated with seismology: ### Key Concepts and Terms 1. **Seismic Waves**: - **P-waves** (Primary waves): Longitudinal waves that travel faster and arrive first.

Fluvial seismology is an interdisciplinary field that combines the study of seismic activity with river and floodplain processes. It involves analyzing seismic waves generated by natural or anthropogenic activities in river systems, including the movement of sediment, erosional processes, and possibly the interactions of these processes with geological structures.

The term "hypocenter" refers to the point within the Earth where an earthquake originates. It is the precise location beneath the surface from which seismic waves radiate outward. The hypocenter is often contrasted with the "epicenter," which is the point on the Earth's surface directly above the hypocenter. The depth of the hypocenter can significantly influence the intensity and impact of the earthquake felt at the surface.

The Headquarters for Earthquake Research Promotion (HERP) is an organization in Japan that focuses on earthquake research, risk assessment, and disaster prevention. Established in 2001, HERP operates under the auspices of the Japanese government and collaborates with various research institutions, universities, and disaster management agencies. The primary functions of HERP include: 1. **Research Coordination:** HERP coordinates and promotes research on earthquakes, including seismic activity, risk assessment, and the development of disaster prevention technologies.

Lunar seismology is the study of seismic activity on the Moon, which involves the analysis of seismic waves generated by moonquakes, meteoroid impacts, and other geological processes. This field of research aims to understand the internal structure and composition of the Moon, as well as its geological history and processes.

It seems like you might be referring to "spiral sections," but if you meant "spiric sections," that term does not have a widely recognized definition in mathematics or related fields.

"Izvestiya Vysshikh Uchebnykh Zavedenii. Radioelektronika" is a scientific journal that publishes research and articles in the field of radio electronics. It is part of a series of journals associated with higher educational institutions in Russia, focusing on various aspects of electrical engineering, telecommunications, and related areas within radio electronics.

A receiver function is a geophysical tool used in seismology to analyze the structure of the Earth's crust and mantle beneath a seismic station. It is particularly useful for studying the transition zone between the crust and the underlying mantle, as well as for investigating lithospheric and asthenospheric properties. Here's how it works: 1. **Seismic Wave Propagation**: When an earthquake occurs, it generates seismic waves that travel through the Earth.

A thrust fault is a type of fault in geology where two blocks of the Earth's crust are pushed together and one block is forced over the other. This typically occurs in regions of compressional stress, where tectonic plates or sections of the Earth's crust collide or converge. In a thrust fault, the angle of the fault plane is typically less than 30 degrees.

The World-Wide Standardized Seismograph Network (WWSSN) was an important global initiative established to improve the detection and analysis of seismic activities around the world. Initiated in the 1960s, the WWSSN aimed to create a uniform system of seismograph stations that could reliably measure and record seismic waves produced by earthquakes, volcanic activity, and even nuclear detonations.

Symbolic interactionism is a sociological framework that focuses on the ways in which individuals create, interpret, and respond to symbols in their social interactions. Developed in the early 20th century, particularly by sociologists like George Herbert Mead and Herbert Blumer, this theory emphasizes the subjective nature of social reality and suggests that meaning is constructed through social interactions rather than being inherent in objects or events.

RepRap Snappy is a type of 3D printer design that is part of the RepRap project, which promotes open-source 3D printing technology. The Snappy design specifically aims to be lightweight, easy to assemble, and capable of producing high-quality prints. Key features of the RepRap Snappy include: 1. **Modular Design**: The Snappy printer often incorporates a modular structure, which means various parts can be easily replaced or upgraded.

Managed to upload the content from the static website cirosantilli.com (OurBigBook Markup source at github.com/cirosantilli/cirosantilli.github.io) to ourbigbook.com/cirosantilli.

Although most of the key requirements were already in place since the last update, as usual doing things with the complex reference content stresses the system further and leads to the exposition of several new bugs.

The upload of OurBigBook Markup files to ourbigbook.com was done with the newly added OurBigBook CLI ourbigbook --web option. Although fully exposed to end users, the setup is not super efficient: a trully decent implementation should only upload changed files, and would basically mean reimplementing/using Git, since version diffing is what Git shines at. But I've decided not to put much emphasis on CLI upload for now, since it is expected that initially the majority of users will use the Web UI only. The functionality was added primarily to upload the reference content.

This is a major milestone, as the new content can start attracting new users, and makes the purpose of the website much clearer. Just having this more realistic content also immediately highlighted what the next development steps need to be.

Once v1.0 is reached, I will actually make all internal links of cirosantilli.com to point to ourbigbook.com/cirosantilli to try and drive some more traffic.

The new content blows up by far the limit of the free Heroku PostgreSQL database of 10k lines. This meant that I needed to upgrade the Heroku Postgres plugin from the free Hobby Dev to the 9 USD/month Hobby Basic: elements.heroku.com/addons/heroku-postgresql, so now hosting costs will increase from 7 USD/month for the dyno to 7 + 9 = 16 UDS/month. After this upgrade and uploading all of cirosantilli.com to ourbigbook.com, Heroku dashboard reads reads:so clearly if we are ever forced to upgrade plans again, it means that a bunch of people are using the website and that things are going very very well! Happy how this storage cost turned out so far.

One key limitation found was that Heroku RAM memory is quite limited at 512MB, and JavaScript is not exactly the most memory economical language out there. Started investigation at: github.com/ourbigbook/ourbigbook/issues/230 Initially working around that by simply splitting the largest files. We were just on the verge of what could be ran however luckily, so a few dozen splits was enough, it managed to handle 70 kB OurBigBook Markup inputs. So hopefully if we manage to optimize a bit more we will be able to set a maximum size of 100 kB and still have a good safety margin.

Made the website navbar and article lists more mobile friendly. Main motivation: improvised demos to people I meet IRL!

I've started rewatching The Water Margin, it is just so good. I'm taking some reasonable notes this time however, because due to Ciro Santilli's bad old event memory I'll forget the details again otherwise.

That type of rebellion symbology could also be useful against the Chinese government. It is interesting that Mao Zedong loved the novel.

The Singer Improved Family refers to a group of sewing machine models produced by the Singer Company, which are based on the design and mechanisms of the original Singer sewing machines. The term usually highlights improvements made in functionality, ease of use, and performance over earlier models. The "Improved" designation generally indicates enhancements in features such as stitch quality, durability, and user-friendly designs. This family of machines has been popular among both casual and professional sewists due to their reliability and efficiency.

Chiaroscuro is a technique used in visual arts, particularly painting and drawing, that employs strong contrasts between light and dark to create a sense of volume and three-dimensionality. The term comes from the Italian words "chiaro" meaning light or clear, and "scuro" meaning dark or obscure. This method enhances the dramatic effect of a piece by highlighting certain areas while casting others into shadow, thereby guiding the viewer's eye and emphasizing the contours and shapes of the subjects portrayed.

Grothendieck topology is a concept from category theory and algebraic geometry that generalizes the notion of open sets in a topological space and allows for the formalization of sheaves and sheaf theory in a more abstract context. It was introduced by the mathematician Alexander Grothendieck in his work on schemes and topos theory.

In the context of sheaf theory and category theory, the concept of "image functor" relates to the way we can understand sheaves on a topological space from their restrictions to open sets through the lens of functoriality. ### Sheaves A **sheaf** is a tool for systematically tracking locally defined data attached to the open sets of a topological space and ensuring that this data can be "glued together" in a coherent way.

As of my last update in October 2023, the term "Human Interference Task Force" does not refer to a widely recognized organization or initiative. However, it may pertain to various contexts, especially in discussions about environmental protection, scientific research, or military operations where human activities may impact natural ecosystems or social systems.
