In case you missed it, mathematicians are pretty obsessed with prime numbers – the limitless ‘atoms’ of the mathematical world that are only divisible by themselves and one.
People are so into them, in fact, that there’s a continual push (and even financial incentive) to compute larger and larger new prime numbers.
But one of the world’s top mathematicians thinks the key to taking things to the next level could come from an ancient Greek algorithm, called the sieve of Eratosthenes.
The sieve of Eratosthenes is pretty much what it sounds like – a mathematical sieve that helps people filter out prime numbers.
Developed by Eratosthenes of Cyrene, a Greek mathematician and astronomer (and former director of the famed Library of Alexandria) back in around 240 BC, the sieve allows people to determine all the primes between a certain set of numbers.
It works by having you write all the numbers out (say 1 to 100) and then you start crossing numbers off in a particular order – the multiples of 2 (other than 2) are first to go, then the multiples of 3, etc. starting from the next number that hadn’t been crossed out.

Quantum mechanics, Carl Sagan once observed, is so strange that “common sense is almost useless in approaching it.” Scientists still don’t understand exactly why matter behaves as it does at the quantum level. Yet they’re getting better at exploiting its peculiar dynamics — in ways that may soon upend the technology business.
One of the most interesting applications is in computing. In theory, quantum computers could take advantage of odd subatomic interactions to solve certain problems far faster than a conventional machine could. Although a full-scale quantum computer is still years off, scientists have lately made a lot of progress on the materials, designs and methods needed to make one.

The changes in culture, markets, and technologies experienced by manufacturing has had a rippling effect into to those institutions charged by societies with the integration of new knowledge.
As we move on further into the 21st century, if we look closely at our university systems we will see that they have, in effect, “reinvented” themselves. Universities are coming to terms in a very proactive sense, with the whole problem of technology change, technology transfer, and the rapid commercialization of technology into useful products and processes.
One way in which this is manifesting itself is the ever increasing exchanges of money, people, and ideas between the university and the industrial sector.
