Fermi problem. This article is about the estimation technique. For Fermi's question about extraterrestrial life, see Fermi paradox. A Fermi problem (or Fermi quiz, Fermi question, Fermi estimate), also known as an order-of-magnitude problem (or order-of-magnitude estimate, order estimation), is an estimation problem in physics or engineering ...
2 days ago · Conceptual structure of contemporary thermal physics is by no means simple, understandable and free of contradictions or ambiguities. As many students claim, it is a rather complicated doctrine which is far from to be easy comprehensible (Meltzer in Am J Phys 72:1432–1446, 2004). Therefore, in this polemic contribution, originally the summer school lecture, we will address some lesser-known ...
3 days ago · More formally, the uncertainty principle is any of a variety of mathematical inequalities asserting a fundamental limit to the product of the accuracy of certain related pairs of measurements on a quantum system, such as position, x, and momentum, p. [ 1 ]
5 days ago · Such problems are abundant in physics. For example, the dynamics of an open quantum system can be described in terms of interactions that take place sequentially with different parts of the system’s environment . In quantum thermodynamics, such a description is commonly employed to model the thermalisation of a system that is brought in ...
4 days ago · Some examples of Lyapunov times are: chaotic electrical circuits, about 1 millisecond; weather systems, a few days (unproven); the inner solar system, 4 to 5 million years. [18] In chaotic systems, the uncertainty in a forecast increases exponentially with elapsed time.
1 day ago · Today, some proponents argue that the FEP even encapsulates what it means for something in the universe to exist at all. “You can read the free-energy principle as a physics of self-organisation ...
