The shaku is a traditional unit of length that originates from Japan. It is part of the shaku system, which also includes other units like the "sun" (1/10 of a shaku) and the "bu" (1/100 of a shaku). The shaku has a historical significance in various traditional Japanese measurements, particularly in construction, carpentry, and other crafts. As defined in the Meiji era, 1 shaku is approximately equal to 30.
Candela is a unit of measurement for luminous intensity in the International System of Units (SI). It quantifies the amount of light emitted by a source in a specific direction. One candela is defined as the luminous intensity of a source that emits monochromatic radiation of frequency 540 × 10^12 Hz and has a radiant intensity of 1/683 watt per steradian. In practical terms, the candela helps in comparing the brightness of different light sources.
The "wa" (和) is a traditional Japanese unit of energy. It is typically used in the context of measuring heat energy, specifically in the field of physics and engineering. One wa is equivalent to approximately 1.96 joules. However, in modern contexts, especially in scientific literature, the joule is the more commonly used unit of energy. The use of "wa" is largely historical and may not be frequently encountered in contemporary measurements.
Arrátel is a term that may not have widespread recognition or usage, and it could refer to different things depending on context. It could be a misspelling or variant of the word "arattle," which is a type of traditional music instrument in some cultures, or it could be related to a specific location, brand, or concept not widely known. If you meant something specific or if it relates to a particular field (e.g.
"Gram" can refer to several things, depending on the context. Here are a few of the most common meanings: 1. **Unit of Mass**: A gram is a metric unit of mass equal to one thousandth of a kilogram (0.001 kg). It is commonly used to measure small weights in fields such as cooking, nutrition, and science.
The term "Maund" can refer to a few different concepts, but it is most commonly associated with "Maundy," especially in a Christian context. Specifically, Maundy Thursday is the day during Holy Week that commemorates the Last Supper of Jesus Christ with his disciples, as well as the institution of the Eucharist (Communion). It is observed on the Thursday before Easter and is part of the Paschal Triduum.

Argumentation theory is a multidisciplinary field that studies the structure, content, and dynamics of arguments, focusing on how they are constructed, understood, and evaluated. It draws from various fields, including philosophy, linguistics, communication, artificial intelligence, and law. Key aspects of argumentation theory include: 1. **Structure of Arguments**: Examination of the components that make up an argument, such as premises, conclusions, and inferential connections.
In the context of algebraic geometry and representation theory, a **complex reflection group** is a specific type of symmetry group that arises in the study of regular polytopes and their symmetries, particularly in complex vector spaces. Formally, a complex reflection group is defined as a finite group generated by complex reflections.

Not the usual bullshit you were expecting from the philosophy of Science, right?
Some notable quoters:
- Jacques Monod has the exact quote as presented here: pubmed.ncbi.nlm.nih.gov/22042272/, though presumably it was in French, TODO find the French version
- youtu.be/AYC5lE0b8os?t=41 A Computational Whole-Cell Model Predicts Genotype From Phenotype- Markus Covert by "Calit2ube" (2013), see also: Section "Whole cell simulation"
- the book Genius: Richard Feynman and Modern Physics by James Gleick (1994) mentions a few incidents of this involving Feynman, see e.g. chapter "New Particles, New Language" where he and fellow theorist Hans Bethe immediately spot problems with experimentalists' data in suspicious results

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.Figure 1. Screenshot of the "Derivative" topic page.
