Cubic fuzzy Einstein aggregation operators and its application to decision-making
International Journal of Systems Science, 2018In this paper, we define some Einstein operations on cubic fuzzy set (CFS) and develop three arithmetic averaging operators, which are cubic fuzzy Einstein weighted averaging (CFEWA) operator, cubic fuzzy Einstein ordered weighted averaging (CFEOWA ...

Nature, 2005 Scientific celebrity has a relativity all of its own. Some scientists are celebrated by their peers, some are treasured by their students, while others are lionized by the public at large. But very few are given the burden of being a celebrity to everyone, everywhere, all the time. Albert Einstein achieved that universality.

The Young Einstein and the Old Einstein
1976In 1911 Einstein, then thirty-two years old, held the post of Professor of Theoretical Physics in the German University at Prague. He had indicated to his friend and former classmate Marcel Grossmann his interest in returning to Zurich to teach at the Polytechnic (The Federal Institute of Technology).

Bose–Einstein condensation in a plasmonic lattice
, 2017Bose–Einstein condensation is a remarkable manifestation of quantum statistics and macroscopic quantum coherence. Superconductivity and superfluidity have their origin in Bose–Einstein condensation. Ultracold quantum gases have provided condensates close

Interdisciplinary Science Reviews, 1969
I have talked about Einstein many times before. That I speak once more on the same subject is due to the fact that in the leisure of my old age I have looked through the letters which Einstein wrote to me during his lifetime. There are more than fifty of them, short and long. I copied them all by hand to make doubly sure of their preservation, and this

Bose-Einstein condensation in the alkali gases: Some fundamental concepts
, 2001The author presents a tutorial review of some ideas that are basic to our current understanding of the phenomenon of Bose-Einstein condensation (BEC) in the dilute atomic alkali gases, with special emphasis on the case of two or more coexisting hyperfine

Solutions of the Einstein and Einstein-Maxwell Equations
Journal of Mathematical Physics, 1969Algebraically degenerate solutions of the Einstein and Einstein-Maxwell equations are studied. Explicit solutions are obtained which contain two arbitrary functions of a complex variable, one function being associated with the gravitational field and the other mainly with the electromagnetic field.

In this chapter we discuss Einstein’s gravitational equations, which state that the presence of matter and energy creates curvature in spacetime, via $${G}_{jk} = 8\pi \kappa {T}_{jk},$$ (0.1) where Gjk = Ricjk − (1∕2)Sgjk is the Einstein tensor, Tjk is the stress-energy tensor due to the presence of matter, and κ is a positive constant.
