Gustav Herglotz was a German mathematician and physicist, known for his contributions to various areas including applied mathematics and physics. He is particularly noted for his work in the fields of geophysics and wave propagation. One of Herglotz's notable contributions is the Herglotz-Voigt theorem, which is related to the characterization of functions as real or complex, and has applications in physics, including the study of elastodynamics.
Halayudha, also known as Halayudha Sūri, was a prominent Indian scholar, writer, and philosopher who lived during the 10th century. He is best known for his work in Sanskrit literature, particularly in the field of the ancient Indian science of rhetoric (alaṅkāra) and poetics.

Li Shanlan refers to a Chinese figure known for his contributions in the fields of natural sciences, particularly during the late Qing Dynasty. He was recognized for his work in geology and mineralogy, and he played a significant role in the introduction of Western scientific concepts to China.
Lakkoju Sanjeevaraya Sarma, often simply referred to as Sanjeevaraya Sarma, is an Indian mathematician known for his contributions to mathematics, specifically in the areas of number theory and combinatorics. He has been recognized for his work in popularizing mathematics and his efforts in education and research.
Li Guoping could refer to various individuals, as it is a common Chinese name. Without additional context, it's difficult to determine exactly who you are asking about.

When Lawrence was five, her father gave up his job so that he could educate her at home.
At Oxford, her father continued to be actively involved in her education, accompanying her to all lectures and some tutorials. Lawrence completed her bachelor's degree in two years, instead of the normal three, and graduated in 1985 at the age of 13 with a starred first and special commendation.

he had tried it once before - with an older daughter, Sarah, one of three children he had by a previous marriage.
That experiment ended after he separated from Sarah's increasingly concerned mother, Jutta. He soon found a woman more in tune with his radical ideas in his next spouse, Sylvia Greybourne
Mahendra Sūri was a renowned scholar, poet, and author known primarily for his contributions to Prakrit literature and Jain texts. His most notable work is the "Māhavīracarita," which is considered a significant text in Jain literature. The work reflects his mastery of Prakrit language and provides insights into Jain philosophy and ethics.
A SUN workstation refers to a type of computer workstation that was developed and marketed by Sun Microsystems, a company known for its high-performance computing products. SUN workstations were primarily based on the SPARC (Scalable Processor Architecture) architecture and ran the Solaris operating system, which is a version of Unix optimized for Sun hardware. SUN workstations were widely used in scientific, engineering, and enterprise environments due to their advanced hardware capabilities and robust software support.
It seems there may be a slight confusion in your question, as "Michio Kuga" does not appear to refer to any widely recognized concept, person, or entity as of my last update in October 2023.
Spiccato is a bowing technique used in string instrument playing, particularly for the violin, viola, cello, and double bass. It involves the bow being bounced lightly on the strings, producing a sharp, distinct sound. This technique allows for a rhythmic articulation of notes, creating a staccato effect while maintaining a level of expressiveness. Spiccato is typically played in the middle of the bow and requires a controlled and relaxed grip to achieve the desired bouncy effect.
Nobushige Kurokawa is a notable figure in the field of mathematics, particularly known for his contributions to algebraic geometry and related areas. In addition to his research work, he may have also been involved in education or mentorship within the mathematical community.
As of my last update in October 2023, Takeo Nakasawa may not be a widely recognized public figure or concept in mainstream discourse. It's possible that he could be a notable person in a specific field such as science, literature, or arts, or might even be a fictional character depending on the context.
Takeo Wada is not a widely recognized figure in mainstream media or literature, at least as of my last knowledge update in October 2023. It's possible that Takeo Wada could be a private individual, a character from a work of fiction, or a person emerging in relevance after that date.
Algebraic K-theory is a branch of mathematics that studies the algebraic structures of rings and schemes using tools from homotopy theory and abstract algebra. The fundamental theorems in algebraic K-theory provide critical insights and relationships between various algebraic objects.
Tetsuji Shioda is a notable figure in the world of aikido, a modern Japanese martial art that focuses on harmonious movement and the redirection of an opponent's energy. Born in 1915, Shioda was a direct student of the founder of aikido, Morihei Ueshiba.

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
