The Acoustical Society of America (ASA) offers several awards to recognize outstanding contributions to the field of acoustics. These awards celebrate achievements in research, education, and service within the acoustical community. Some of the notable awards include: 1. **Silver Medal Awards**: These are awarded in various categories such as musical acoustics, psychological and physiological acoustics, and noise. They honor individuals for their significant contributions to research and technology in specific areas of acoustics.
Seashell resonance, often associated with the characteristic sound produced when a seashell is held to the ear, is an intriguing acoustic phenomenon. When you place a seashell against your ear, you might hear a sound reminiscent of ocean waves or a soft, soothing hum. This sound is not actually the ocean or water contained within the shell; rather, it is the result of the amplification of ambient noise by the shape of the shell.
The Lovász conjecture is a well-known conjecture in combinatorial discrete mathematics, specifically in the field of graph theory. Proposed by László Lovász in 1970, the conjecture pertains to the structure of edge-coloring in a certain class of graphs known as Kneser graphs. To explain the conjecture, we first need to define Kneser graphs.
"Free drift" can refer to different concepts depending on the context, but in a general sense, it often describes a state where something is allowed to move or operate without restraint or control.
As of my last knowledge update in October 2023, there is no widely recognized individual or entity named Anton Sushkevich. It is possible that Anton Sushkevich could refer to a private individual or a lesser-known figure in a specific field, such as business, academia, or arts, but without additional context, it is difficult to provide specific information.

Nothing makes the fact that your life is an illusion clearer than animations of molecular biology processes. You just have no idea what is going on inside your own body right now!
And don't get Ciro Santilli started on the brain and the impossibility of free will.
And yet, we live, oblivious to all of it.

Luminiferous aether by Ciro Santilli 40 Updated 2025-07-16
Can you just imagine what if luminiferous aether was one single fixed rigid body? This is apparently what Maxwell believed, Subtle is the Lord by Abraham Pais (1982) page 111 quoting his entry to Encyclopedia Britannica:
There can be no doubt that the interplanetary and interstellar spaces are not empty but are occupied by a material substance or body, which is certainly the largest, and probably the most uniform, body of which we have any knowledge.
Then it would provide a natural space coordinate for the entire universe!
Apparently Einstein was the first to completely say: let's just screw this aether thing completely then, it's getting too complicated, and we don't really need it. As Wikipedia puts it well, in very unencyclopedic tone[ref]: Aether fell to Occam's razor.
Aleksandr Aleksandrov (1912–2001) was a prominent Russian mathematician known for his significant contributions to various areas of mathematics, particularly in topology and geometry. He is most noted for his work in the field of general topology and for his contributions to the theory of convex polyhedra. One of his key achievements was the development of the concept of Alexandrov spaces, which generalizes some properties of geometric spaces, particularly in relation to curvature and metric spaces.
Pentagon, in the context of computers and technology, often refers to a specific computer architecture or a computational model. However, it appears that you may be referring to one of the following: 1. **Pentagon (the building)**: The Pentagon, located in Arlington, Virginia, is the headquarters of the United States Department of Defense. It has an extensive amount of computer systems and networks that support military operations and logistics.
Aleksei Pogorelov could refer to various individuals, as the name may not be widely recognized in public discourse. If you are referring to a specific person, context, or field (such as science, arts, sports, etc.
Nikolai Kapitonovich Nikolski was a prominent Soviet and Russian mathematician known for his contributions to various fields, including analysis, function theory, and complex analysis. Born on April 29, 1898, and passing away on October 20, 1979, Nikolski's work particularly focused on topics such as approximation theory, operator theory, and the study of analytic functions.
As of my last update in October 2023, Gregory Garibian does not appear to be a widely recognized figure in public domains such as politics, entertainment, or academia. It's possible that he could be a private individual or a figure who has gained prominence after my last update.
Leonid Yatsenko does not appear to be a widely recognized public figure or concept as of my last knowledge update in October 2023. It is possible that he may be an individual known in specific local contexts or in certain professional fields, but there may not be significant information available about him in broader public discourse.
Maria Orbeli was a notable figure in the field of physiology and a prominent scientist in the early to mid-20th century. She made significant contributions to our understanding of various physiological processes, with a focus on the nervous system and sensory perception. Her work is particularly recognized in the context of Russian and Soviet scientific research.

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
