Matrioshka brain
A matrioshka brain[1][2] is a hypothetical megastructure of immense computational capacity powered by a Dyson sphere. It was proposed in 1997 by Robert J. Bradbury (1956–2011[3]). It is an example of a class-B stellar engine, employing the entire energy output of a star to drive computer systems.[4] This concept derives its name from the nesting Russian matryoshka dolls.[5] The concept was deployed by Bradbury in the anthology Year Million: Science at the Far Edge of Knowledge.[6][7]
Todays Thought
Usually, terrible things that are done with the excuse that progress requires them are not really progress at all, but just terrible things.

Todays Thought
The principal goal of education in the schools should be creating men and women who are capable of doing new things, not simply repeating what other generations have done; men and women who are creative, inventive, and discoverers, who can be critical and verify, and not accept, everything they are offered.
