Webimpact of Cohen’s ideas on the practice of set theory, as well as on the philosophy of mathematics, has been incalculable. Curiously, though, despite the importance of Cohen’s work and the passage of nearly fty years, forcing remains totally mysterious to the vast majority of math-ematicians, even those who know a little mathematical logic.
The exact value of the continuum in the above Cohen model, and variants like for cardinals in general, was worked out by Robert M. Solovay, who also worked out how to violate (the generalized continuum hypothesis), for regular cardinals only, a finite number of times.
