Ever wished you could attend that talk — if only you didn’t have to hike the Rockies, or swim across the Atlantic, to get there; if only it could have been scheduled the following week, because this week is finals; if only you could watch it from your desk, or for that matter directly from your bed?

TCS+, a series of online seminars in theoretical computer science, will solve all your worries. The seminars are run using Google Hangouts. The speaker and slides are broadcast live, as well as recorded and made available online. Anyone can watch the live broadcast, or even join the live audience and participate. The goal is to make engaging talks accessible to the widest possible audience, thereby ensuring a carbon-free dissemination of ideas across the globe.

See below for a schedule of upcoming talks. (To sign up for our mailing list and be informed of upcoming talks, go here.) Times are shown in UTC. After importing into your own calendar, times will automatically adjust to your time zone. Otherwise, for East Coast, subtract 5 hours; for West Coast, subtract 8; for central Europe, add 1. During daylight saving time, add 1 to the above.
