Analytic continuation by Ciro Santilli 40 Updated 2025-07-16
visualizing the Riemann hypothesis and analytic continuation by 3Blue1Brown (2016) is a good quick visual non-mathematical introduction is to it.
The key question is: how can this continuation be unique since we are defining the function outside of its original domain?
The answer is: due to the identity theorem.

Each player on a team typically dons a specific number on their jersey, which not only helps identify them on the field but also holds significance in terms of tradition and player roles.
Fictitious forces, also known as pseudo forces or inertial forces, are apparent forces that arise in non-inertial reference frames—frames of reference that are accelerating or rotating. These forces are not the result of any physical interaction but are instead perceived due to the acceleration of the observer's frame of reference.
Station P, officially known as Ocean Station P (OSP), is a significant oceanographic measurement site located in the North Pacific Ocean. Positioned approximately 50°N latitude and 145°W longitude, it is part of a long-term monitoring program established to study various oceanic and atmospheric phenomena.

The Talbot effect, also known as the Talbot phenomenon, is an optical phenomenon that occurs when coherent light (such as from a laser) is illuminated on a periodic structure, such as a grating. When the light passes through the grating, it creates a series of diffraction patterns that repeat at specific distances, known as the Talbot distance.
Stuart Campbell is a well-known obstetrician and gynecologist, recognized for his contributions to the field of prenatal imaging and ultrasound. He gained prominence for developing advanced techniques in obstetric ultrasound, particularly in the use of 3D and 4D imaging. His work has significantly enhanced the ability to visualize fetal development and diagnose various conditions before birth. Campbell has been associated with various medical institutions and has also been involved in teaching and training other professionals in the use of ultrasound technology.
Subgroup analysis is a statistical method used in research and clinical trials to examine the effects of an intervention or treatment across different subsets or groups within a larger population. By breaking down the population into subgroups, researchers can identify whether the treatment is more or less effective in specific segments of the population based on characteristics such as age, gender, ethnicity, baseline health status, or other relevant factors.

Super Bit Mapping (SBM) is a digital audio processing technology developed by Sony. It is primarily used to enhance the quality of audio when converting from a higher bit depth to a lower bit depth, such as from 24-bit to 16-bit formats, which is a common requirement for CD audio. The main goal of SBM is to minimize distortion and maintain audio fidelity during the bit-depth reduction process.
SuperPaint is a graphic design and painting software that was developed for the Macintosh platform. Originally released in 1985 by Silicon Beach Software, SuperPaint was one of the first graphics programs for Apple computers, and it allowed users to create and edit images with a variety of features that were innovative for the time. SuperPaint supported pixel-based editing as well as vector graphics, enabling artists to create detailed illustrations.
Walter Tollmien was a notable German mathematician and engineer, recognized for his significant contributions to the field of fluid dynamics. He is best known for the Tollmien-Schlichting waves, which are critical in understanding boundary layer theory and instabilities in fluid flows. His work has had a lasting impact on aerodynamics and the study of turbulent flows, influencing various applications in engineering and physics.
Susan B. Davidson is a prominent computer scientist known for her work in the fields of databases, knowledge representation, and artificial intelligence.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
