Science Buddies mission is to help students to build their literacy in science and technology so they can become productive and engaged citizens in the 21st century. The site has personalized learning tools, over 15,000 pages of scientist-developed subject matter (including experiments based on the latest academic research), and an online ...
Kenneth Lafferty Hess (born January 22, 1953) is an engineer, author, entrepreneur, and philanthropist. Hess is the founder and president of Science Buddies, a non-profit organization dedicated to furthering science literacy through the creation of free resources and services for K-12 students, teachers, and families.
Time crystals: A state of matter where an object can have movement even at its lowest energy state. Hidden states of matter: Phases that are unattainable or do not exist in thermal equilibrium, but can be induced e.g. by photoexcitation. Microphase separation: Constituent units forming diverse phases while also keeping united.
High-energy-density matter (HEDM) is a class of energetic materials, particularly fuel, with a high ratio of potential chemical energy output to density, usually termed "thrust-to-weight ratio", hence "high energy density". The substances are extremely reactive, therefore potentially dangerous, and some consider them impractical.
Energy quality is a measure of the ease with which a form of energy can be converted to useful work or to another form of energy: i.e. its content of thermodynamic free energy. A high quality form of energy has a high content of thermodynamic free energy, and therefore a high proportion of it can be converted to work; whereas with low quality ...
In regular cold matter, quarks, fundamental particles of nuclear matter, are confined by the strong force into hadrons that consist of 2–4 quarks, such as protons and neutrons. Quark matter or quantum chromodynamical (QCD) matter is a group of phases where the strong force is overcome and quarks are deconfined and free to move.
High-energy-density physics (HEDP) is a subfield of physics intersecting condensed matter physics, nuclear physics, astrophysics and plasma physics.It has been defined as the physics of matter and radiation at energy densities in excess of about 100 GJ/m 3 equivalent to pressures of about 1 Mbar (or roughly 1 million times atmospheric pressure).
Mass–energy equivalence states that all objects having mass, or massive objects, have a corresponding intrinsic energy, even when they are stationary.In the rest frame of an object, where by definition it is motionless and so has no momentum, the mass and energy are equal or they differ only by a constant factor, the speed of light squared (c 2).
