The Edison Manufacturing Company was an American company founded by Thomas Edison in 1887, primarily focused on the production of electric light bulbs and other electrical equipment. Initially established as a subsidiary of Edison's broader electrical ventures, the company was integral to the development and commercialization of electric lighting technology.
Ellerman bombs are a type of astrophysical phenomenon associated with flares occurring in the lower solar atmosphere, particularly in the chromosphere and transition region of the Sun. They are characterized by localized, explosive bursts of energy and are believed to be related to the magnetic activity and interactions in the Sun. Ellerman bombs typically manifest as temporary brightenings in the H-alpha solar spectrum, indicating significant energy release and associated with the presence of magnetic reconnection events.
Elaine Sadler is an astrophysicist recognized for her work in the field of astronomy and cosmology, particularly in the areas of galaxy formation and evolution, as well as the distribution of galaxies in the universe. She has contributed significantly to our understanding of the large-scale structure of the universe and the behavior of dark matter.
The 955 acorn triode is a type of vacuum tube that was commonly used in mid-20th century electronics. The term "acorn" refers to its compact, cylindrical shape, which resembles an acorn. These tubes were designed for use in applications that required a small size and light weight, such as in portable radios and other low-power devices. The 955 triode specifically has a variety of applications, including audio amplification and signal detection.
A proportioning valve is a component used in hydraulic brake systems, particularly in vehicles, to manage and optimize the braking performance. Its primary function is to ensure that the appropriate amount of hydraulic pressure is distributed to the front and rear brakes, adapting to various driving conditions, loads, and vehicle dynamics.
Endotherms, commonly referred to as warm-blooded animals, are organisms that can regulate their body temperature internally, maintaining it at a relatively constant level regardless of the external environmental conditions. This ability is primarily due to metabolic processes that generate heat. Examples of endotherms include mammals and birds.
The English Electric Canberra is a British jet-powered bomber and reconnaissance aircraft that was designed and built by English Electric. Its first flight took place in 1949, and it entered service with the Royal Air Force (RAF) in 1951. The Canberra was notable for being one of the first jet bombers to be used by the RAF and played a significant role during the Cold War. The aircraft featured a high-wing design, straight wings, and was powered by twin jet engines.
"Envoi" can refer to different concepts depending on the context. Here are a few common meanings: 1. **Literary Term**: In poetry, an "envoi" (or "envoy") is a short stanza at the end of a poem, often used to address a particular person or to summarize the poem's themes. It serves as a concluding remark or message.
The concept of an étale topos arises from algebraic geometry and the study of schemes, particularly in the context of Grothendieck's pursuit of a more geometric point of view on algebraic structures. In basic terms, a topos is a category that behaves similarly to the category of sets, but with additional structure that allows for the handling of sheaves, logic, and categorical properties.
C. H. Waddington refers to Conrad Hal Waddington, a British developmental biologist and geneticist known for his innovative contributions to the fields of genetics and embryology. He is particularly recognized for his work on "epigenetics," a term he coined in the 1940s to describe the processes that lead to the regulation of gene expression and the development of organisms, beyond the influences of the genetic code itself.
Eugene Koonin is a prominent biologist and bioinformatician known for his work in the fields of evolutionary biology, genomics, and computational biology. He is particularly recognized for his research on the origins and evolution of life, as well as the evolutionary dynamics of viruses. Koonin has made significant contributions to our understanding of the evolutionary relationships among different organisms and the role of horizontal gene transfer in evolution.
Vojvodina is an autonomous province located in northern Serbia, with a diverse cultural and historical heritage. The region has a complex history influenced by various ethnic groups, political changes, and historical events. Here is an overview of its history: ### Prehistoric and Ancient Times - **Early Settlements**: The area of Vojvodina has been inhabited since prehistoric times, with archaeological evidence of cultures such as the Vinča and the Iron Age Celts.
Infragravity waves are a type of low-frequency wave typically found in ocean environments. They have periods that range from approximately 30 seconds to several minutes, which makes them significantly longer than regular wind-driven surface waves, which often have periods of a few seconds to around 10 seconds. Infragravity waves are generated by the interaction of regular ocean waves with the shoreline and the seafloor. When wind-generated waves break, they can create these longer-period waves through non-linear interactions.
Misorientation generally refers to a condition in which two objects, such as materials, crystals, or cells, are oriented in a way that does not align with each other. This term is commonly used in various fields, including materials science, crystallography, and biology. In the context of crystallography, misorientation describes the angular difference between the crystallographic directions or planes of two adjacent grains or crystals.
Instructions per second (IPS) is a measure of a computer's performance, specifically its processing speed. It quantifies how many individual instructions a CPU (Central Processing Unit) can execute in one second. This measurement helps to gauge the efficiency and power of a processor in performing tasks.
International Packet Switched Service (IPSS) refers to a telecommunications service that enables the transfer of data packets across international networks using packet-switching technology. Unlike traditional circuit-switched networks, which establish a dedicated circuit for each call, packet-switched networks break data into packets that can take different routes to reach the destination, where they are reassembled.
Internet Explorer (IE) is a web browser developed by Microsoft, first released as part of the add-on package Plus! for Windows 95 in 1995. Over the years, Microsoft released multiple versions of Internet Explorer, gradually adding new features and capabilities. Below is a summary of the major versions and their release dates: ### Internet Explorer Version History 1. **Internet Explorer 1.0** - August 1995 - Initial release, part of Windows 95 Plus!
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!
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.Figure 1. Screenshot of the "Derivative" topic page.
