Hace 5 días · The Dirac equation is a relativistic wave equation derived by Paul Dirac in 1928 that describes all spin-1/2 massive particles. It is consistent with quantum mechanics and special relativity, and implies the existence of antimatter and spin.
Hace 5 días · The quantum theory of magnetic charge started with a paper by the physicist Paul Dirac in 1931. [10] In this paper, Dirac showed that if any magnetic monopoles exist in the universe, then all electric charge in the universe must be quantized (Dirac quantization condition). [11]
Hace 17 horas · The delta function was introduced by physicist Paul Dirac, and has since been applied routinely in physics and engineering to model point masses and instantaneous impulses. It is called the delta function because it is a continuous analogue of the Kronecker delta function, which is usually defined on a discrete domain and takes values 0 and 1.
Hace 3 días · In addition to Zwicky’s tired light theory, Gupta introduces the idea of evolving “coupling constants,” as hypothesized by Paul Dirac. Coupling constants are fundamental physical constants that govern the interactions between particles. According to Dirac, these constants might have varied over time.
Hace 2 días · Styled and with features to match the Masters M23 power amp, NAD's M66 streaming DAC/preamp takes on all-comers as both a digital and vinyl hub with Dirac onboard First announced in the spring of 2023, unexpected delays to the arrival of NAD's M66 have only heightened anticipation of this flagship 'streaming DAC/preamplifier' - especially among owners of the company's Eigentakt-based M23 power ...
Hace 4 días · Entre 1926 y 1927, Fermi y el físico inglés Paul .A.M. Dirac desarrollaron de forma independiente nuevas estadísticas, ahora conocidas como estadísticas de Fermi-Dirac, para manejar las partículas subatómicas que obedecen al principio de exclusión de Pauli.
Hace 4 días · Historical Insight: Physicist Paul Dirac observed large numbers coincidences in cosmology, suggesting underlying connections that imply fine-tuning. Anthropic Principle: Proposed in the 1970s by Brandon Carter, it states that the universe’s laws appear fine-tuned to allow for observers like us to exist.
