noun, Chemistry, Physics.
a transuranic element. Symbol: Es; atomic number: 99.
a metallic transuranic element artificially produced from plutonium. Symbol: Es; atomic no: 99; half-life of most stable isotope, 252Es: 276 days
discovered in the debris of a 1952 U.S. nuclear test in the Pacific, named 1955 for physicist Albert Einstein (1879-1955).
einsteinium ein·stein·i·um (īn-stī’nē-əm)
A radioactive transuranic element synthesized by neutron irradiation of plutonium or other elements. Its longest-lived isotope is Es 254 with a half-life of 275 days. Atomic number 99; melting point 860°C.
A synthetic, radioactive metallic element of the actinide series that is usually produced by bombarding plutonium or another element with neutrons. It was first isolated in a region near the explosion site of a hydrogen bomb. Its longest-lived isotope is Es 254 with a half-life of 276 days. Atomic number 99; melting point 860°C. See Periodic Table.
noun, Astronomy. 1. Einstein’s solution of the equations of general relativity with the cosmological constant. The solution describes an isotropic, homogeneous, static universe with no cosmological redshift.
noun, Physics, Astronomy. 1. formerly, gravitational redshift. noun 1. (astronomy) a small displacement towards the red in the spectra, caused by the interaction between the radiation and the gravitational field of a massive body, such as the sun
noun, Physics. 1. (def 2).
