The iconic MIT home page Spotlight features a daily-changing image and design that focuses on advances in research, technology and education taking place at the Institute. Though some Spotlights do run multiple days - for example Friday's spot usually runs through the weekend, we work very hard to maintain the daily-changing tradition. We've combed our servers and have compiled a digital archive of the Institute home page through the years - well over 2000 images. Enjoy!

Warm welcomeToday’s Spotlight features photographs, taken by Dominick Reuter, of MIT's Freshman Convocation.

“You belong to an extremely select group,” MIT President L. Rafael Reif told the incoming Class of 2018 at this year’s Freshman Convocation, the traditional welcoming ceremony for the Institute’s new freshmen.

Pointing to the 7.9 percent acceptance rate for a group of applicants that is already heavily self-selected to represent the elite of graduating high school students, he told this “extremely strong and talented group” that although they undoubtedly had other options, “you all made an extremely smart choice” by coming to MIT. Recalling his own uncertainties when he first arrived here, he said he quickly realized “this community was like an extended family.”

The MIT home page Spotlight showcases the research, technology and education advances taking place at the Institute every day.

What makes it as a Spotlight image is an editorial decision by the MIT News Office based on factors that include timeliness, promotion of MIT's mission, the balance of interest to both internal and external audiences, and appropriateness.

We do welcome ideas and submissions for spotlights from community members, but please note we are not able to accommodate all requests. We are unable to run event previews or promotions as spotlights; for those looking to promote an event, we are happy to include your listing as an event headline on the homepage (when space is available) and you are free to submit an Of Note to the MIT News office. For more information, e-mail the spotlight team.

Today’s Spotlight image is a photograph, by Weishun Xu and Yuhao Zhang , showing a beam of white light that passes through the angular-selective sample as if it was transparent glass.

Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color or polarization, selectivity based on the direction of propagation has remained elusive.

But now, for the first time, MIT researchers have produced a system that allows light of any color to pass through only if it is coming from one specific angle; the technique reflects all light coming from other directions. This new approach could ultimately lead to advances in solar photovoltaics, detectors for telescopes and microscopes, and privacy filters for display screens.
