first computers. It was only physically built much later on. We refer to the
textbook of Cormen et al. [1] for a nice introductory overview of algorithms.
We emphasize that:
Computers = Comput ing Machineries
10.5 Computer science in the 21st century
Nowadays, computers (and computing) are omnipresent. The envisioned
ubiquitous computing of Mark Weiser (Xerox Parc chief scientist) is here.
Computers are abundant and versatile. They are abundant because we probably
carry dozens of CPUs without being conscious of them (cell phones, cameras,
music players, etc.). Furthermore, computing is impacting all traditional
sciences. It is now common to speak of computational sciences. For example,
biology is evolving as systems biology which allows researchers to perform a
rich set of simulation-prediction-experiences (and finally cross-validate these
numerical simulations in wet labs.
The science of computing is Computer Science (CS): Computer science raises
deep theoretical questions. We recommend the Harel's book [3]: “Computers
Ltd.: What They Really Can't Do.” Computer science also brings important
novel technologies. For example, in medical imaging a novel imaging technique
is called diffusion tensor magnetic resonance imagery, or DT-MRI. Computing
will definitively participate in the integration science of the 21st century.
