European Bunny is a math teacher from England, who is here with a math-teacher friend from China. She reports her friend plans to use smoots in a homework assignment now, based in part on the video above.

Tamas K-L watched the storm over the Charles this afternoon.

Oliver Smoot, the man who became a unit of measurement, was back in town today to serve as grand marshal of the 100th anniversary of MIT's moving day - the celebration of the school's moving from the Back Bay to Cambridge.

RoadTrip New England snapped him as he rode past the markers bearing his name on the bridge.

Curt Nickish caught him being measured to make sure he still had an ear (the bridge being, of course, 364.4 smoots long, plus or minus an ear): Read more.

A 45-year-old Harvard man jumped off the Massachusetts Avenue Bridge shortly before noon. According to the Suffolk County District Attorney's office:

Troopers were able to bring the man from the water into a State Police vessel and transport him to a nearby dock, from where he was taken to Boston Medical Center. Based on the facts and circumstances available thus far, the incident does not appear to be the result of criminal conduct and the man is expected to survive.

For the second day in a row, Boston and Cambridge firefighters and State Police responded to the Massachusetts Avenue bridge on a report of a possible jumper, only to find no evidence on the bridge or in the water that somebody had actually jumped.

Firefighters used thermal imagers and sonar to search the water, after the report of a possible jumper mid-span came in shortly before 11:50 p.m.

The bridge was shut in both directions. Around 12:20 a.m., Boston firefighters began packing up and leaving.

Shortly after 4 p.m., Boston and Cambridge firefighters and Boston and State police began rushing to the Mass. Ave. Bridge on a report of a sailboat tipping over in the wind and dumping somebody in the water. Just as firefighters were about to begin their "tech rescue," however, the person managed to get back in the boat and make his way to shore on the Cambridge side - where he was met by troopers and Cambridge firefighters. He declined medical attention.

David Cole spotted the Wienermobile on the Mass. Ave. bridge around 6 p.m.

WBUR interviews Silvi Naci, who came up with the idea of "stitching" Boston and Cambridge together.

Among other things, she reports very few hipsters actually contributed to the project, so there.
