1 dzień temu · Quantum computing. Quantum System One, a quantum computer by IBM from 2019 with 20 superconducting qubits [1] A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of both particles and waves, and quantum computing leverages this behavior using specialized hardware.
1 godzinę temu · Quantum field theory. In quantum field theory, the mass gap is the difference in energy between the lowest energy state, the vacuum, and the next lowest energy state. The energy of the vacuum is zero by definition, and assuming that all energy states can be thought of as particles in plane-waves, the mass gap is the mass of the lightest particle.
1 dzień temu · An object resting on a surface and the corresponding free body diagram showing the forces acting on the object. The normal force N is equal, opposite, and collinear to the gravitational force mg so the net force and moment is zero. Consequently, the object is in a state of static mechanical equilibrium. In classical mechanics, a particle is in ...
1 godzinę temu · The replication crisis [a] is an ongoing methodological crisis in which the results of many scientific studies are difficult or impossible to reproduce. Because the reproducibility of empirical results is an essential part of the scientific method, [2] such failures undermine the credibility of theories building on them and potentially call ...
1 dzień temu · The Flying Spaghetti Monster (FSM) is the deity of the Church of the Flying Spaghetti Monster, or Pastafarianism, a parodic new religious movement that promotes a light-hearted view of religion. It originated in opposition to the teaching of intelligent design in public schools in the United States. According to adherents, Pastafarianism (a portmanteau of pasta and Rastafarianism) is a "real ...
1 dzień temu · A view from a space station in a low Earth orbit (LEO) at about 400 km (250 mi), with yellow-green airglow visible at Earth's horizon, where roughly at an altitude of 100 km (62 mi) the boundary between Earth and outer space lies and flying speeds reach orbital velocities.. A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per ...
