Abigail Adams Biography. Abigail Smith (Adams) was born on November 11, 1744, in Weymouth, Massachusetts. She was the second child born to Elizabeth Quincy Smith and the Reverend William Smith. Her father was Pastor of Weymouth's North Parish Congregational Church and one of the best educated and most prosperous citizens of the community.
13. Alan Turing, one of the pioneers of (theoretical) computer science, made many seminal scientific contributions to our field, including defining Turing machines, the Church-Turing thesis, undecidability, and the Turing test. However, his important discoveries are not limited to the ones I listed.
The Turing machine was invented in 1936 by Alan Turing, who called it an a-machine (automatic machine).hus, Turing machines prove fundamental limitations on the power of mechanical computation. While they can express arbitrary computations, their minimalistic design makes them unsuitable for computation in practice: actual computers are based on different designs that, unlike Turing machines, use random access memory.
