The Niels Bohr International Gold Medal is awarded by the Niels Bohr Institute in Denmark to honor individuals who have made significant contributions to the field of physics, particularly in the areas related to the work of the renowned physicist Niels Bohr. The medal serves to recognize advancements in understanding fundamental questions in physics, encompassing both theoretical and experimental approaches.
The Oliver E. Buckley Condensed Matter Prize is awarded annually by the American Physical Society (APS) to recognize outstanding contributions to the field of condensed matter physics. Established in 1978, the prize honors significant achievements such as groundbreaking research, discoveries, or innovations that advance the understanding of condensed matter systems. Winners of the prize are recognized for their influential work and contributions to theories and applications within the field, which can include areas such as solid-state physics, materials science, and more.
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.
Condensed matter physics is a branch of physics that focuses on the physical properties of condensed phases of matter, particularly liquids and solids. It encompasses a wide range of topics, including the study of crystal structures, electronic properties, magnetism, superconductivity, and the quantum behavior of matter at very low temperatures, among others.

Ciro Santilli 37 Updated 2025-06-17 +Created 1970-01-01The Doppler effect is a phenomenon that occurs when there is a change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. This effect is commonly associated with sound waves, but it also applies to electromagnetic waves, such as light. ### Key Points of the Doppler Effect: 1. **Source and Observer Movement**: - If the wave source moves toward the observer, the waves are compressed, resulting in a higher frequency (or shorter wavelength).

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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.
