The Statue of Liberty in Seattle refers to a lesser-known replica of the famous Statue of Liberty in New York City. This smaller version is located on Alki Point in West Seattle. The statue was created as part of a private project by the local Seattle community in the 1950s and is not officially sanctioned by the United States government. The Seattle version of the statue was created in the 1950s to honor education, and it stands at approximately 15 feet tall.
Differential structures refer to the mathematical frameworks that allow us to study and analyze the properties of smooth manifolds using the tools of differential calculus. A smooth manifold is a topological space that locally resembles Euclidean space and has a differential structure that enables the definition of concepts such as smooth functions, differentiability, and tangent spaces. Here are some key aspects of differential structures: 1. **Manifolds**: A manifold is a topological space that is locally homeomorphic to Euclidean space.
A Clifford module bundle is a mathematical construct that arises in the context of differential geometry and representation theory, particularly in relation to spin geometry and the manipulation of spinors. To understand what a Clifford module bundle is, let's break this down into a few components: 1. **Clifford Algebras:** A Clifford algebra is an algebra that is generated by a vector space equipped with a quadratic form.
The Bagger-Lambert-Gustavsson (BLG) action is a theoretical framework in the context of supersymmetric gauge theories, specifically dealing with three-dimensional (3D) theories that include gauge fields and matter fields. The action was proposed independently by Craig Bagger, Neil Lambert, and Per Gustafsson around 2006 as a way to describe certain aspects of multiple M2-branes in string theory.
In the context of string theory, a domain wall refers to a type of solitonic solution in higher-dimensional field theories that can arise within the framework of string theory. Specifically, domain walls can represent interfaces or boundaries in spacetime where the physical properties of the fields change, often associated with a change in vacuum states or phases of the underlying field theory. In more technical terms, a domain wall is typically a (d-1)-dimensional object embedded in a d-dimensional spacetime.
Freund–Rubin compactification is a method used in the context of string theory and higher-dimensional theories of gravity, particularly in relation to the compactification of extra dimensions. The concept was introduced by Justin Freund and Marvin Rubin in the early 1980s. In string theory and related theories, we often encounter scenarios where the observable universe is modeled as a four-dimensional spacetime (3 spatial dimensions plus time) embedded within a higher-dimensional space.
"Real structure" can refer to different concepts depending on the context in which it is used. Here are a few interpretations: 1. **Mathematical Context**: In mathematics, "real structure" might refer to a structure that is defined over the real numbers. For instance, in topology or algebra, a "real structure" can mean a property or attribute of a mathematical object that involves real numbers, such as real vector spaces or real manifolds.
Killer Sudoku is a variant of the traditional Sudoku puzzle that adds an additional layer of complexity by introducing "cages." In a Killer Sudoku, the standard Sudoku rules still apply: the goal is to fill a grid (typically 9x9) with digits from 1 to 9 such that each row, column, and 3x3 subgrid contains each digit exactly once. The unique feature of Killer Sudoku is the presence of these cages, which are outlined by dotted or heavy lines.
Superglass can refer to a couple of different things depending on the context: 1. **Insulation Material**: In construction and insulation, "superglass" may refer to a type of advanced insulation material, often made from fiberglass or mineral wool. These materials are designed to be highly effective at insulating buildings, improving energy efficiency, and reducing heat loss.
Has some good mentions, but often leaves you wanting more details of how certain things happened, especially the early days stuff.
Does however paint a good picture of several notable employees, and non-search projects from the early 2000's including:
- the cook dude
- porn cookie guy
- the unusual IPO process
Paints a very positive picture of the founders. It is likely true. They gave shares generously to early employees. Tried to allow the more general public to buy from IPO, by using a bidding scheme, rather than focusing on the big bankers as was usual.
The introduction mentions that Google is very interested in molecular biology and mining genetics data, much like Ciro Santilli! Can't find external references however...
Two of the most compelling areas that Google and its founders are quietly working on are the promising fields of molecular biology and genetics. Millions of genes in combination with massive amounts of biological and scientific data are an excellent match for the Google search engine, the tremendous database the company has in place, and its immense computing power. Already, Google has downloaded a map of the human genome and is working closely with biologist Dr. Craig Venter and other leaders in genetics on scientific projects that may lead to important breakthroughs in science, medicine, and health. In other words, we may be heading toward a time when people can google their own genes.
The book gives good highlight as to why Google became big: search was just an incredibly computationally intensive task. From very early days, Largey were already making up their own somewhat custom compute systems from very early days, which naturally led into Google custom hardware later on. Google just managed to pull ahead on the reinvest revenue into hardware loop, and no one ever caught them back. This feels more the case than e.g. with Amazon, which notoriously had to buy off dozens of competitors to clear the way.

. The Sudoku Cube is a variation of the classic Sudoku puzzle presented in a three-dimensional format. It combines elements of traditional Sudoku with the structure of a cube, similar to a Rubik's Cube. In a typical Sudoku puzzle, the goal is to fill a grid (commonly 9x9) with numbers such that each row, column, and designated subgrid (like 3x3 boxes) contains all of the numbers without repetition.
The Davenport constant is a concept from additive number theory, particularly in the context of additive bases. It is defined in relation to a finite set of integers.
Kneser's theorem is a result in combinatorial topology and algebraic topology that deals with the intersection properties of certain families of subsets of a finite set. Specifically, it provides a bound on the size of families of subsets that can be chosen from a finite set, under the constraint that certain intersections are empty.
Cryogenic particle detectors are highly sensitive instruments designed to measure and detect low-energy particles, often at very low temperatures. These detectors operate at cryogenic temperatures, typically below 100 Kelvin (-173°C), where thermal noise is significantly reduced. This sensitivity allows them to detect very weak signals from particles, such as photons, electrons, or interactions from dark matter.

Personal knowledge base software recommendation threads:
TODO look into those more:
- roamresearch.com/ no public graphs
- nesslabs.com/roam-research-alternatives a bunch of open source alternatives to it
- Trillium Notes. Notable project! Pun unintended!
- Stroll giffmex.org/stroll/stroll.html. How to publish? How to see tree?
- tiddlyroam joekroese.github.io/tiddlyroam/ graph rather than text searchable ToC. Public instance? Multiuser?
- Athens github.com/athensresearch/athens rudimentary WYSIWYG
- Logseq github.com/logseq/logseq no web interface/centralized server?
- itsfoss.com/obsidian-markdown-editor. Closed source. They have an OK static website publication mechanism: publish.obsidian.md/ram-rachum-research/Public/Agents+aren't+objective+entities%2C+they're+a+model but leaf node view only for now, no cross source page render. They are committed to having plaintext source which is cool: twitter.com/kepano/status/1675626836821409792

Major downsides that most of those personal knowledge databases have:
- very little/no focus on public publishing, which is the primary focus of OurBigBook.com
- either limited or no multiuser features, e.g. edit protection and cross user topics
- graph based instead of tree based. For books we need a single clear ordering of a tree. Graph should come as a secondary thing through tags.

Pyotr Kapitsa, full name Pyotr Leonidovich Kapitsa, was a renowned Russian physicist who made significant contributions to various fields of physics, particularly in low-temperature physics and the study of superfluidity. He was born on July 8, 1894, in Kronstadt, Russia, and passed away on April 8, 1984.
Volcanic lightning, also known as "dirty thunderstorms," refers to lightning that occurs within or above a volcanic eruption. This phenomenon is caused by the interaction of volcanic ash and gas ejected during an eruption. The ash particles collide with one another and with other gases, leading to the buildup of electrical charges within the volcanic plume. When the electrical charge becomes strong enough, it can result in lightning strikes.
The Jucys-Murphy elements are a set of operators that arise in the theory of symmetric groups and representations of the symmetric group algebra. They are named after the mathematicians Alexander Jucys and J. D. Murphy, who introduced them in the context of representation theory.
Ionization instability refers to a phenomenon in the context of atomic or molecular systems, particularly in plasma physics and astrophysics, where the ionization of particles (atoms or molecules) leads to an unstable state. This instability can manifest in various ways, often influencing the behavior of charged particles in a given environment.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
