Destination data

With its 28-mile-long azure lake, framed by the snow-capped Alps, the picturesque city of Como, Italy, is a popular vacation destination for entertainment royalty, including George Clooney, Madonna, and Sting.

Paparazzi keep track of these famous visitors, but how can municipal officials monitor the way the other 1 million tourists who visit Como each year travel among the districts and attractions in this medieval city?

Picture perfect plates

Whether they are surfing the web in search of surf and turf, or browsing for the perfect grass-fed beef burger, more than 90 percent of U.S. consumers search online for restaurants, according to a study by market research firm Chadwick Martin Bailey.

The unintended consequences of rationality

A century of economic theory assumed that, given their available options, humans would always make rational decisions. Economists even had a name for this construct: homo economicus, the economic man.

Have you ever met a human? We’re not always the most rational bunch. More recent economic theory confronts that fact, taking into account the importance of psychology, societal influences and emotion in our decision-making.

IACS Seminar Series

The IACS Seminar series will resume in February 2019.

IACS seminars are generally held every other Friday during the academic year, and are free and open to the public. No registration is required. Unless otherwise noted, all seminars will take place at Harvard University in Maxwell Dworkin G115.

***NEW TIME*** Due to the new class schedule, seminars will now be held from 1:30-2:30pm. Light refreshments will be served from 1-1:30pm.

Built for speed: Designing exascale computers

“Imagine a heart surgeon operating to repair a blocked coronary artery.

Someday soon, the surgeon might run a detailed computer simulation of blood flowing through the patient’s arteries, showing how millions of red blood cells jostle and tumble through the small vessels. The simulation would identify the best repair strategy.

With a fast enough computer, it could all be done in a few minutes, while the operation is under way.”

The need for speed

As described in the Summer 2014 issue of Topics, Harvard researchers are pushing the limits of computing power to achieve new breakthroughs in science and engineering. What will high-performance computing mean for you?
