Scientific wonder will sweep across New York City on Saturday as curious attendees gather at the World Science Festival to explore gravitational waves, count fish with biologists, and stare up at the stars underneath the Brooklyn Bridge.

Following a thrilling opening night celebration of the life and work of Dr. Oliver Sacks, nine scientists took home Kavli Prizes on Day 2 of the 2016 World Science Festival in recognition of their achievements in astrophysics, nanoscience and neuroscience. The prizes, which awarded every other year by The Norwegian Academy of Science and Letters and come with a cash award of $1 million each, honored the LIGO Scientific Collaboration’s successful detection of gravitational waves, pioneering efforts in atomic force microscopy, and for the discovery of mechanisms that allow experience and neural activity to remodel brain function.

Day 3 is packed chock-full of fascinating events for scientists at every level of expertise. The most advanced attendees will connect with leaders in their fields during World Science U for a Day. Future scientists from schools across New York City (and around the world, through the power of the internet) will join physicist Gabriela González of the LIGO Scientific Collaboration at Google’s New York headquarters for an inspiring conversation about what’s possible with a career in science.

Day 2 of the World Science Festival features a full slate of programs that kicks off with the prestigious Kavli Prizes, which are awarded every other year to the top scientists studying astrophysics, nanoscience and neuroscience. Storytelling takes center stage during a sold-out performance of The Moth, featuring personal stories told by esteemed scientists. The Big Ideas Series series begins on Thursday night with two in-depth conversations featuring some of science’s brightest minds. One dives deep into the nature of dark matter and another explores the big questions surrounding what can science explain about the human experience.

With less than one week to go before the 2016 World Science Festival begins in New York City, co-founder and physicist Brian Greene joined Stephen Colbert on “The Late Show” on Wednesday night to debut a demonstration tailor-made to blow minds and officially set a new Guinness World Record. The experiment is just one of dozens that are set to transform Washington Square Park during Street Science, a free day of science fun for children and families scheduled for Sunday, June 5th, 2016.
