Hace 13 horas · Richard Phillips Feynman (/ ˈ f aɪ n m ə n /; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model.
Hace 13 horas · General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton's law of universal gravitation ...
Hace 1 día · Physics theories of the 19th century assumed that just as surface water waves must have a supporting substance, i.e., a "medium", to move across (in this case water), and audible sound requires a medium to transmit its wave motions (such as air or water), so light must also require a medium, the "luminiferous aether", to transmit its wave motions.
Hace 13 horas · Modernism is an early 20th-century movement in literature, the visual arts and music, emphasizing experimentation, abstraction, and subjective experience. Philosophy, politics and social issues, are also aspects of the movement, which sought to change how 'human beings in a society interact and live together'. [2]
Hace 13 horas · e. The cosmic microwave background ( CMB or CMBR) is microwave radiation that fills all space in the observable universe. It is a remnant that provides an important source of data on the primordial universe. [1] With a standard optical telescope, the background space between stars and galaxies is almost completely dark.
Hace 1 día · A genomics approach has sought to characterise LUCA of modern organisms by identifying the genes shared by Archaea and Bacteria, members of the two major branches of life (with Eukaryotes included in the archaean branch in the two-domain system). 355 genes appear to be common to all life; their functions imply that the LUCA was anaerobic with the Wood–Ljungdahl pathway, deriving energy by ...
