How do we gather stories about ACM's past before it's too late? The charter of the ACM History Committee is "to foster preservation and interpretation of the history of the ACM and its role in the development of computing."
DEPARTMENT: From the president
In a recent column, I questioned whether there was any "science" in computer science. This provoked a great many responses that provided some very valuable perspective. I have come away from this foray into computer 'science'
DEPARTMENT: Letters to the Editor
Concerning the proposed Research Works Act, introduced in the U.S. Congress in 2011, Moshe Y. Vardi's "Editor's Letter" "Why ACM?" (Sept. 2012) left me a little confused as to Vardi's own position on both the law and open

Three breakthrough experiments involving photons have extended coherence times and indicated scalable production.
Drilling down to more detail on a computer screen, or moving out to see the context, is basic. But it's hardly simple and, after 20 years, innovations are still occurring.

This lifting of data structure thinking to the relational level has long inspired computer scientists. In "An Introduction to Data Representation Synthesis," the authors aim at elevating data structure programming to the relational
We consider the problem of specifying combinations of data structures with complex sharing in a manner that is declarative and results in provably correct code.
How do birds flock and fish school? How do individuals in a social network reach agreement, even though they are often only influenced by other like-minded individuals? How can one engineer a swarm of robots to behave like
Algorithms lay the grounds for numerical simulations and, crucially, provide a powerful framework for their analysis. The new area of natural algorithms may reprise in the life sciences the role differential equations have long
COLUMN: Last byte
Last month (November 2012) we posted a
trio of brainteasers
concerning the use of a balance scale to determine the weight of various numbers of coins. Here, we offer solutions to all three. How did you do?
Sanjeev Arora talks about proof, intractability, and finding the best way to approximate problems.
