There must be thousands of photos and videos online of the thousands of people attending the March for Science – Boston yesterday, in concert with many, many more people in similar marches around the world that day.  In Boston, MIT Media Lab director Joi Ito spoke to the crowd, saying:

In the ’60s, the President galvanized America under a dream of science. This time, we have an attack on science.  We shouldn’t take that attack and cower in fear. We should take it as a challenge, as an opportunity.  We have all these people who care about science, marching all over the world.  It’s not only our opportunity — it’s our obligation — to take advantage of this energy to come together.  If you’re a scientist, or even if you’re not a scientist, reach out to the people who are not here today, who aren’t excited about science. Don’t argue with them. Share your passion. Get them to join the team. We have to come together under a passion for science, rather than fear, fighting, and arguing. And I think we can do it.

Registration is now open for two Saturday-morning sessions of Science on Saturday, on May 20 at MIT’s Lincoln Laboratory (244 Wood Street in Lexington).   The topic will be The Sound of Science.  All children (5-17 years) must be escorted by an adult, and every adult must be escorted by a child or children.  Children under 5 are not admitted.  Admission is free but each person attending must be registered.  Space is limited, so register online soon for either Session 1 (9AM to 10:30AM) or Session 2: 10:45AM to 12:15PM). Register an adult first, then a child, then others. Adults must bring government photo identification.  See other rules on the registration pages.

The Russian School of Math will host its Spring Math Carnival on April 29, 5-8PM — free and open to the public — at its headquarters (200 Wells Avenue, Newton). It will feature games, exhibit booths, math puzzles, and math art for the entire family.

On May 6, 12:30-3PM, the Massachusetts State Science and Engineering Fair will showcase more than more than 300 of the “best of the best” high-school science fair research and design projects from across the state, at the Johnson Athletics Center at MIT. $500,000 worth of scholarships and prizes will be awarded at a ceremony at 3:30PM. MIT notes that parking will be especially difficult that day, so take public transportation or leave extra time.
