Dianna Cowern. Dianna Leilani Cowern (born May 4, 1989) is an American science communicator. She is a YouTuber; she uploads videos to her YouTube channel Physics Girl explaining various physical phenomena. She worked in partnership with the PBS Digital Studios from 2015 until 2020, when she discontinued her partnership. [ 5]
Tracking (particle physics) In particle physics, tracking is the process of reconstructing the trajectory (or track) of electrically charged particles in a particle detector known as a tracker. The particles entering such a tracker leave a precise record of their passage through the device, by interaction with suitably constructed components ...
STAR detector. The STAR detector (for Solenoidal Tracker at RHIC) is one of the four experiments at the Relativistic Heavy Ion Collider (RHIC) in Brookhaven National Laboratory, United States. [ 1][ 2][ 3] The primary scientific objective of STAR is to study the formation and characteristics of the quark–gluon plasma (QGP), a state of matter ...
The TRT (Transition Radiation Tracker) central section, the outermost part of the Inner Detector, assembled above ground and taking data from cosmic rays [28] in September 2005. The Inner Detector [ 1 ] [ 2 ] [ 3 ] [ 29 ] begins a few centimetres from the proton beam axis, extends to a radius of 1.2 metres, and is 6.2 metres in length along the ...
MinutePhysics is an educational YouTube channel created by Henry Reich in 2011. The channel's videos use whiteboard animation to explain physics -related topics. Early videos on the channel were approximately one minute long. [ 2] As of March 2024, the channel has over 5.7 million subscribers.
A flow tracer is any fluid property used to track the flow velocity (i.e., flow magnitude and direction) and circulation patterns. Tracers can be chemical properties, such as radioactive material, or chemical compounds, physical properties, such as density, temperature, salinity, or dyes, and can be natural or artificially induced.
Single-particle tracking ( SPT) is the observation of the motion of individual particles within a medium. The coordinates time series, which can be either in two dimensions ( x, y) or in three dimensions ( x, y, z ), is referred to as a trajectory. The trajectory is typically analyzed using statistical methods to extract information about the ...
The Feynman Lectures on Physics. The Feynman Lectures on Physics is a physics textbook based on a great number of lectures by Richard Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". [ 1] The lectures were presented before undergraduate students at the California Institute of Technology (Caltech), during 1961–1964.
