Down with the Big Bang

The "big bang" theory and Down syndrome.

I am convinced that some of the most joyful, life-changing conventions in our field are those that focus on families with children having Down syndrome. Whole families come. Some appear with babes in arms. Clinicians named Pueschel, Crocker, Kumin, Falvey, Rosenberg and many others hold impromptu clinics in halls, lobbies, and special session rooms. It all goes so well because these parents hun...

The Big Bang is bang on.

The Big Bang Theory

The first theoretical evidence for the Big Bang came from Alexander Friedmann in 1922, when he showed that Albert Einstein’s theory of general relativity predicted that the universe was either expanding or contracting. Einstein was so upset with this result that he introduced a cosmological constant into his theory which would make the universe static. Later he said that this was his biggest bl...

STRUCTURAL OPTIMIZATION USING BIG BANG-BIG CRUNCH ALGORITHM: A REVIEW

The big bang-big crunch (BB-BC) algorithm is a popular metaheuristic optimization technique proposed based on one of the theories for the evolution of the universe. The algorithm utilizes a two-phase search mechanism: big-bang phase and big-crunch phase. In the big-bang phase the concept of energy dissipation is considered to produce disorder and randomness in the candidate population while in ...

Big-bang Nucleosynthesis with the Nacre Compilation

Observations of light isotopes have flourished and in particular, high quality Li observations in the halo stars have been accumulated. Thus, it is timely to reassess the determination of the baryonic density of the Universe in the light of advances in nuclear physics and astronomical observations. (For details see K. Olive, these proceedings.) Most of the important reactions for Li production ...
