An earworm happens when you have the “inability to dislodge a song and prevent it from repeating itself” in your head, explains Steven Gordon, M.D ., neurologist at UC Health and assistant ...
In physics, a mass balance, also called a material balance, is an application of conservation of mass [1] to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in ...
In meteorology, an air mass is a volume of air defined by its temperature and humidity. Air masses cover many hundreds or thousands of square miles, and adapt to the characteristics of the surface below them. They are classified according to latitude and their continental or maritime source regions. Colder air masses are termed polar or arctic ...
The fluctuation–dissipation theorem says that when there is a process that dissipates energy, turning it into heat (e.g., friction), there is a reverse process related to thermal fluctuations. This is best understood by considering some examples: Drag and Brownian motion. If an object is moving through a fluid, it experiences drag (air ...
The knives are out, but the scissors are sheathed as Daniel Craig debuts a long hairdo in a first look from Rian Johnson’s next mystery movie. The director dropped a photo on social media ...
One was an airplane mechanic like Ken Lemmons, and the other was a master of the air. After safely flying to Africa, he died on base in a Jeep accident. Because, I do so much fiction, it kept ...
Since at least the 1990s, scientists have researched whether the now-ubiquitous radiation associated with mobile phone antennas or cell phone towers is affecting human health. [1] Mobile phone networks use various bands of RF radiation, some of which overlap with the microwave range. Other digital wireless systems, such as data communication ...
An ice mass balance buoy (IMB) allows scientists studying sea ice to measure its temperature and the evolution of its interfaces remotely. The autonomous mass balance buoys usually consist of a data controller module and a temperature string. Some ice mass balance buoys also include acoustic sounders above and below ice measuring the positions ...
