Georges Canguilhem (1904–1995) was a French philosopher and historian of science, best known for his contributions to the philosophy of biology and medicine. He is celebrated for his work on the concepts of life, health, illness, and the epistemological foundations of the biological sciences. Canguilhem is particularly noted for his claim that the concept of health must be understood in the context of individual variability and capacities rather than as a fixed norm.
The Centre for Underground Physics (CUP) in Pyhäsalmi, Finland, is a research facility dedicated to conducting studies in various fields of physics, particularly in areas like particle physics, astroparticle physics, and underground astrophysics. The facility is situated in a former copper mine, which provides a unique environment for scientific experiments, as the underground location helps shield sensitive detectors from cosmic radiation and other background noise that can interfere with measurements.
Diplacusis is a auditory phenomenon in which a person perceives a single sound as being divided into two distinct sounds, often with a disparity in pitch or tone. This can occur in one ear or both ears and is typically related to issues with the auditory system, such as damage to the cochlea or auditory nerve. Individuals with diplacusis might hear the same musical note or sound at slightly different frequencies or tones, leading to a confusing or disorienting auditory experience.
Charles Renouvier (1815–1903) was a French philosopher and a prominent figure in the development of 19th-century French thought. He is best known for his work in the philosophy of free will, his critiques of determinism, and his contributions to neo-Kantianism. Renouvier was a strong advocate for the concept of free will and emphasized the importance of individual autonomy in moral and philosophical contexts.
George William Hill (1838-1914) was a prominent British astronomer and mathematician known for his work in celestial mechanics. He is best known for the development of the Hill equations and contributions to the stability of the moon's motion among celestial bodies. His work laid important groundwork for the study of the motion of satellites and the mathematical principles governing their orbits.
The 3rd meridian east is a line of longitude that is situated 3 degrees east of the Prime Meridian, which is defined as 0 degrees longitude and runs through Greenwich, London, United Kingdom. The 3rd meridian east runs from the North Pole to the South Pole, traversing various countries and regions. In Europe, it passes through parts of countries such as Germany and Italy, while in Africa, it crosses through countries like Libya and Tanzania.
The 54th meridian west is a line of longitude located 54 degrees west of the Prime Meridian, which runs through Greenwich, London. Like all lines of longitude, the 54th meridian west runs from the North Pole to the South Pole. This meridian passes through several regions, including parts of eastern Canada, various islands in the Atlantic Ocean, and the eastern coast of South America, specifically through countries like Argentina and Brazil.
The term "560 mm artillery" typically refers to a category of very large caliber artillery pieces, specifically those with a barrel diameter of 560 millimeters. This size of artillery is rarely used in conventional military operations and is generally reserved for specific applications such as siege artillery or coastal defense. One notable example of 560 mm artillery is the Japanese "Type 5 560 mm howitzer," which was developed during World War II.
The 61st meridian east is a line of longitude that is 61 degrees east of the Prime Meridian, which is located at 0 degrees longitude. It runs from the North Pole to the South Pole, passing through various countries. In terms of geography, the 61st meridian east passes through parts of Russia, particularly Siberia, and also crosses through Kazakhstan and several other regions. This meridian is often used in various fields including geography, navigation, and timekeeping.
The 63rd meridian west is a line of longitude that is 63 degrees west of the Prime Meridian, which runs through Greenwich, London. This meridian runs from the North Pole to the South Pole, passing through various countries in the Northern Hemisphere, including parts of Canada and the United States, and then extending into the Southern Hemisphere, where it crosses through parts of South America. In Canada, it traverses areas in Newfoundland and Labrador.
The number 64,079 is simply a numeric value. If you provide more context, I can help you understand its significance or relevance. For example, it could represent a monetary amount, a population count, or something else entirely.
The Riemann–Lebesgue lemma is a fundamental result in Fourier analysis, dealing with the behavior of the Fourier coefficients of integrable functions. It asserts that if \( f \) is an integrable function on the real line (or on a finite interval), then the Fourier coefficients of \( f \) tend to zero as the frequency goes to infinity.
The number 75 is a whole number that follows 74 and precedes 76. It can be used in various contexts such as mathematics, measurement, and more. In terms of mathematics, 75 is an integer that can be expressed in different forms: - **Prime Factors**: 75 can be factored into prime numbers as \(3 \times 5^2\). - **Even or Odd**: 75 is an odd number.
A1703 zD6 is a galaxy that is notable for being one of the most distant known galaxies, located at a redshift of approximately z=6. This places it around 13.1 billion light-years away from Earth, making it a subject of significant interest in the study of the early universe.
Functional neuroimaging is a set of techniques used to visualize and measure brain activity by detecting changes associated with blood flow. It provides insights into the brain's functioning, allowing researchers and clinicians to study how different areas of the brain activate in response to various tasks, stimuli, or conditions. Common methods of functional neuroimaging include: 1. **Functional Magnetic Resonance Imaging (fMRI)**: This technique measures brain activity by detecting changes in blood oxygenation levels.
The Function Field Sieve (FFS) is an algorithm used for factoring large integers, particularly those that are difficult to factor with classical methods. It extends the ideas of the number field sieve (NFS), which is currently one of the most efficient known methods for factoring large composite numbers, especially those with large prime factors.
Abel Klein is a prominent figure in the field of mathematics, particularly known for his contributions to functional analysis and harmonic analysis. He has made significant impacts through his research and studies, but there may be multiple individuals with the same name.
The Abraham–Minkowski controversy refers to a longstanding debate in theoretical physics regarding the momentum of light in a medium and the way that electromagnetic waves interact with matter. Specifically, it revolves around two competing formulations for the momentum of light in a dielectric medium, attributed to physicists Max Abraham and Hermann Minkowski, both of whom derived different expressions for the momentum of photons in a medium.

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!
We have two killer features:
  1. 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-calculus
    Articles 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.
