A dropsonde is a type of meteorological instrument that is used to collect data about the atmosphere. It is typically deployed from aircraft, particularly during research flights into severe weather systems like hurricanes or winter storms. The dropsonde is released from the aircraft and falls freely through the atmosphere, transmitting data back to the aircraft in real time. It measures various atmospheric parameters, including temperature, humidity, pressure, and wind speed/direction, as it descends.
A circumhorizontal arc is a type of optical phenomenon that can be seen in the sky, specifically associated with the refraction of sunlight through ice crystals in cirrus or cirrostratus clouds. It appears as a colorful band of light occurring at the same altitude as the sun but usually appears as a horizontal band or arc that is parallel to the horizon. The circumhorizontal arc is a result of the sunlight passing through ice crystals that have flat, horizontally oriented top surfaces.
A cyanometer is a device that was historically used to measure the blueness of the sky or the intensity of the color blue in the atmosphere. It consists of a circular arrangement of colored disks, typically with shades of blue. By comparing the color of the sky with the disks, observers could gauge the sky's hue and determine its blueness quantitatively.
Earth's shadow is the region in space where sunlight is blocked by Earth, creating areas of darkness and varying illumination. This shadow plays a significant role in various astronomical phenomena, particularly during lunar and solar eclipses. There are two main components of Earth's shadow: 1. **Umbra**: This is the innermost and darkest part of the shadow, where all direct sunlight is blocked.
The term "infralateral arc" is not commonly used in standard anatomical or scientific literature; it might refer to a specific concept in a specialized context (such as neurology, surgery, or a specific study) that is not widely recognized. However, in general anatomical terminology, "infralateral" typically refers to a position that is below and to the side of a particular structure.
In the context of astronomy, a "mirage" usually refers to optical phenomena that can distort the appearance of celestial objects, making them seem altered or displaced from their actual positions. While the term is most commonly associated with atmospheric phenomena on Earth, such as the mirages seen on hot pavement, similar principles can apply when observing astronomical objects.
"Subsun" generally refers to a phenomenon related to atmospheric optics, particularly involving the appearance of a bright spot on the ground or water surface beneath a cloud. This occurs when sunlight shines through a gap in the clouds, creating a concentrated beam of light that illuminates a specific area below, often surrounded by shadow. Subsun can also be used to describe similar optical effects, such as those involving halos or other light phenomena.
A 1s Slater-type function is a mathematical function used in quantum chemistry and atomic physics to describe the spatial distribution of electrons in an atom, particularly for the innermost shell of electrons (the 1s orbital). Slater-type orbitals (STOs) are defined by their exponential decay and can be used to effectively approximate the wavefunctions of electrons.
Audiology is the branch of science and medicine that focuses on the study of hearing, balance, and related disorders. Audiologists are professionals who specialize in diagnosing, managing, and treating hearing loss and balance issues. They work with individuals of all ages, from infants to the elderly, to assess their hearing abilities and develop appropriate treatment plans.
Aphasias are a group of language disorders that result from damage to specific areas of the brain responsible for language processing. These disorders can affect various aspects of language, including speaking, understanding, reading, and writing. Aphasias typically occur after a stroke, traumatic brain injury, or other neurological conditions. There are several types of aphasia, including: 1. **Broca's Aphasia**: Characterized by difficulty in producing speech.
The auditory system is the sensory system responsible for the perception of sound. It includes the anatomical structures and pathways that allow us to detect, transmit, and interpret sound waves. The auditory system can be divided into several key components: 1. **Outer Ear**: This includes the pinna (the visible part of the ear) and the ear canal. The outer ear collects sound waves and directs them toward the eardrum.
The International Society of Audiology (ISA) is a professional organization that focuses on the fields of audiology and hearing science. Founded in 1966, the ISA aims to promote the study and practice of audiology globally, facilitate communication and collaboration among audiology professionals, and advance research and education in the field. Key objectives of the ISA include: 1. **Networking and Collaboration**: Bringing together audiologists, researchers, and practitioners from around the world to share knowledge and experiences.
"Analog ear" doesn't seem to be a commonly recognized term or concept in popular usage or technical literature up to October 2023. It could potentially refer to a variety of topics depending on context, such as: 1. **Audio Technology**: It might refer to analog audio systems, where sound is captured and reproduced in a continuous wave format rather than in digital form. This might involve analog headphone technologies.
A cochlear implant is a medical device designed to provide a sense of sound to individuals who have severe to profound hearing loss and do not benefit from conventional hearing aids. Unlike hearing aids, which amplify sound, cochlear implants bypass damaged portions of the ear and directly stimulate the auditory nerve. ### Components of a Cochlear Implant: 1. **External Processor**: This is worn behind the ear and captures sound from the environment. It converts sound into digital signals and sends them to the internal implant.

White was awarded the Nobel Prize in Literature in 1973, becoming the first Australian to receive this honor.
Beverly Jane Fry is not a widely recognized public figure, historical person, or term that is commonly known. It is possible that she could be a private individual, or perhaps a character in a specific context, such as literature or media. Without additional context about who she is or what she is associated with, it's difficult to provide specific information.

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.
