Join us this spring for the sixth annual nexus, the Northeast's largest conference dedicated to critical thinking and science education.

It's all going down in New York City the weekend of April 11th through 13th, 2014.

We're excited to feature a keynote by physicist Lawrence Krause, who's authored bestsellers like the Physics of Star Trek,

and who just starred with Richard Dawkins in a new film last year called The Unbelievers.

This is in addition to a great lineup of other speakers like Paul Offutt,

expert on vaccines and infectious disease,

and Katie Coleman, veteran astronaut for NASA.

Of course, Massimo and I will be there taping a live episode of the rationally speaking podcast,

and so will the cast of The Skeptics Guide to the Universe. Get your tickets now at nexus.org. That's

nec-s-s-S-S-D-org. Registration prices go up after March 20th, so don't wait. Get your tickets today.

Rationally speaking is a presentation of New York City skeptics dedicated to promoting critical thinking, skeptical inquiry, and science education.
