The Cambridge Science Festival is the national leader in its field, with over 200 activities and events spanning 10 days, April 13-22, in Cambridge, greater Boston, and beyond. #CambSciFest is too much to keep in your head. You can filter this year’s online schedule of events by date, age (family/teens/adults), cost, venue, day of the week, time of day, or organizer — and then export your filtered events to your personal calendar.  Browse the lists of Museum of Science activities and exhibits and week-long youth and family workshops. Some events require pre-registration or tickets, and most are free.  Some highlights:

• The opening-night symposium on April 13, 7:30-9:30PM at Harvard’s Science Center ($15):  The Continuing Education of Eugene Mirman, in which this endlessly curious comedian attempts to learn about cognitive neuroscience from MIT professor Rebecca Saxe.
• The Science Carnival and Robot Zoo on Saturday, April 14, 12-4PM at the Cambridge Public Library (free).  Meet robots, explore VR, launch rockets, make slime, and use liquid-nitrogen to make ice cream.
• The Year in Science: Cocktails and Trivia on April 18, 6-8PM ($15) for adults at Mamaleh’s Delicatessen.
• The Science of Local Food on April 21, 10AM-7PM (free drop-in, with fees for some workshops), at Boston Public Market.
