Roger Temam is a prominent French mathematician known for his work in the fields of partial differential equations and mathematical analysis. He has contributed significantly to the study of variational methods, fluid dynamics, and the mathematical modeling of physical processes. Temam is also recognized for his influence in the field of applied mathematics and for training a generation of mathematicians through his teaching and mentorship.
The SIAM Fellow designation is an honor awarded by the Society for Industrial and Applied Mathematics (SIAM) to recognize distinguished members for their contributions to the fields of applied and computational mathematics. SIAM Fellows are selected based on their significant achievements in research, education, and service to the community. The recognition aims to highlight individuals who have made substantial impacts through their work, whether in academia, industry, or other areas related to applied mathematics.
Henri Pitot (1695–1771) was a French engineer and hydraulic scientist best known for his invention of the Pitot tube, which is used to measure fluid flow velocity. The Pitot tube operates by comparing static and dynamic pressure, allowing the determination of the fluid's velocity based on the differences in pressure. This device is widely used in various applications, including aircraft speed measurement, wind tunnel testing, and fluid flow analysis in pipes and channels.
Harry Bateman was a prominent British mathematician known for his work in the field of differential equations and mathematical physics. He is particularly recognized for his contributions to the theory of special functions and for formulating what are now known as Bateman's formulas, which relate to the solutions of certain types of differential equations. Bateman also played a significant role in the development of mathematical tools and techniques used in physics and engineering.
Yuwen Zhang can refer to different individuals or contexts depending on specific domains such as academia, literature, business, or other fields. As of my last update in October 2023, there isn't a widely recognized figure or specific event associated with that name that would provide a clear answer without additional context.
Tullio Levi-Civita (1873–1969) was an Italian mathematician and an influential figure in the fields of mathematics and physics, particularly known for his work in differential geometry, tensor calculus, and the mathematical foundations of general relativity. He is best known for the Levi-Civita symbol and the Levi-Civita connection, which are fundamental concepts in the study of tensors and differential geometry.
In the context of mathematics, specifically in the fields of differential geometry and analysis, a **fiber derivative** often refers to a derivative that is taken with respect to a specific direction in a fiber bundle. ### Fiber Bundles and Fibers - A **fiber bundle** consists of a base space, a total space, and a typical fiber. The fibers are the pre-images of points in the base space and can have complicated structures depending on the problem at hand.
The MTZ black hole, or the "M1, T1, and Z1" black hole, is a theoretical type of black hole that arises from a specific model of gravitational collapse and can be described using various metrics in the field of general relativity. The term is often used in the context of particular studies or research papers that focus on certain properties of black holes, such as their thermodynamic behavior, stability, or the nature of their event horizons.
Superoscillation refers to a phenomenon where a function, such as a wave or signal, oscillates at frequencies higher than its highest Fourier component. In simpler terms, it allows a signal to display rapid oscillations that exceed the fastest oscillation of the components that make it up. This can occur in various fields, including optics, signal processing, and quantum mechanics.
A Reliability Block Diagram (RBD) is a graphical representation used to analyze the reliability of a system and its components. In an RBD, components of a system are represented as blocks, and the arrangement of these blocks illustrates how the components interact in terms of their reliability. **Key Features of Reliability Block Diagrams:** 1. **Components:** Each block represents an individual component of the system, such as a machine, part, or subsystem.

Ciro Santilli is for abortion rights of women, until very late in pregnancy.
But it's not something that he would do himself, unless under extreme cases.
Transmon by Ciro Santilli 40 Updated 2025-07-16
Used e.g. in the Sycamore processor.
The most basic type of transmon is in Ciro's ASCII art circuit diagram notation, an LC circuit e.g. as mentioned at youtu.be/cb_f9KpYipk?t=180 from Video "The transmon qubit by Leo Di Carlo (2018)":
+----------+
| Island 1 |
+----------+
   |   |
   X   C
   |   |
+----------+
| Island 2 |
+----------+
youtu.be/eZJjQGu85Ps?t=2443 from Video "Superconducting Qubits I Part 1 by Zlatko Minev (2020)" describes a (possibly simplified) physical model of it, as two superconducting metal islands linked up by a Josephson junction marked as X in the diagram as per-Ciro's ASCII art circuit diagram notation:
+-------+       +-------+
|       |       |       |
| Q_1() |---X---| Q_2() |
|       |       |       |
+-------+       +-------+
The circuit is then analogous to a LC circuit, with the islands being the capacitor. The Josephson junction functions as a non-linear inductor.
Others define it with a SQUID device instead: youtu.be/cb_f9KpYipk?t=328 from Video "The transmon qubit by Leo Di Carlo (2018)". He mentions that this allows tuning the inductive element without creating a new device.

Japanese Brazilians by Ciro Santilli 40 Updated 2025-07-16
Japanese Brazilians are either model children, or they're good for nothings. There is no intermediate.

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
