It's all smoot...

September 9, 2006 1:25 PM

"364.4 Smoots plus one ear" is the official length of the MIT bridge between Cambridge and Boston. In 1962, pledges to an MIT fraternity were ordered to measure the bridge using the shortest among them, Oliver R. Smoot, as a measuring stick. Since then, members of the fraternity have repainted the marks on the bridge twice a year. Oliver Smoot's daughter Sherry, eventually went to MIT but was not used to remeasure the bridge since she was shorter than her father. Her brother Stephen, also an MIT student, was too tall. Oliver, of course, was just right. He eventually went from being a unit of measure to controlling units of measure: in 2001 he was chosen to be chairman of ANSI and in 2003 he was selected to be president of ISO.

That's awesome. Thanks for the great post.

What a great, quirky little post! Most amusing, thanks, SCDB.

An MIT friend told me the story of the bridge a couple years ago, but I didn't know the guy became chairman of ANSI! That's just too good to be true.

Google Earth recognizes the "smoot" as a unit of measure and will offer distances in that unit. (In case you're curious, a Smoot is officially 67 inches.)

What an excellent FPP!

Funny...I'm familiar with Smoots, seems everyone in Cambridge knows about it (or asks about it when they see the MIT bridge markings) but I had no idea Smoot went on to be involved in standards! Couldn't have been written beter.

Boo! Must fix that. (typity typity) There.

Now, to submit the patch.

Oh, yeah. Just for the record. 55 exasmoot (and an ear) is almost one parsec, and the speed of light is 213085.53 smoots per nanofortnight. Now you know.

Yesterday I swam 1175 smoots!

Working this unit into everyday conversation is going to take a bit of work.

Fortunately Google has a built-in meters to smoots converter.
posted by clevershark at 2:13 PM on September 9, 2006

I can't believe this has never been on MeFi before. I could swear I learned about it here, but the search for smoot turns up nada, other than the Google calculator can do unit conversions into smoots.

The bridge is usually referred to as the /Harvard/ bridge, or the Mass. Ave. bridge, not the MIT bridge. Anecdotally, this is because MIT students structurally analyzed it and gladly ceded any naming rights, although the chronology doesn't really work out (the bridge was built while the Institvte was still on its pre-1916 Boston campus near Copley Square).

In the 1920s, it was so badly deteriorating that it was referred to as the xylophone bridge; a popular student anecdote involved a suicide-attempting student who changed his mind while falling from the bridge and was saved because a passerby threw in a plank loosened the bridge's disintegration, which he used to float ashore.

Ah, the Smoot Bridge.

I remember when my brother (an MIT grad) first showed it to me many moons ago.

Fun group of people, those Institute geeks.

I remember walking accross that bridge in early 2002 and wondering what the hell the markings were all about.

I think we're all smitten with smoots.

Oliver is about 65 (most sources seem to give the bridge-pledge-rush-haze date as 1958). Unless he uses gravity boots, I'm guessing the paradigm has undergone some contraction — and the Old Smoot ain't what he used to be.

I am also a smoot! I feel the need to respond in this format. I hope someone asks for my height soon. Hm, now I just need an unusual measure of weight/mass...

I'm about one smoot high as well!

He must have been intensely interested in measuring things as a young man, and hence infamy enough to warrant such a stunt. He was a measurements geek!

In the 80's the bridge was limited to one lane each way because of it was structurally unsound.
posted by rdr at 8:53 PM on September 9, 2006

Not only is this an excellent post, but it just reminded me about a guy I know named Tom Smoot. That name always gave me a a laugh and now there's another story about it.

Speaking of which, apparently the Millenium Falcon was able to do the Kessel run in just under 2.17577507 × 10¹⁷ smoots. That is all.

And those students who originally did this, they were just so fantastically lucky that the shortest among them was actually named SMOOT! How fantastic is that? If he'd been a Higginbotham, or a Steinberg or a Williams, I dunno, just wouldn't have had that ring.
posted by flapjax at midnite at 3:44 AM on September 10, 2006

I wonder if he was really chosen because he was the shortest guy around or because he had the best name. Smoot. I love it, fantastic story, thanks.

Ha! I'm two inches short of a smoot.
posted by deborah at 10:23 AM on September 10, 2006

So, is an ear roughly equivalent to an inch then? In that case I am one smoot and 2 ears tall.

In the Spenser novel Early Autumn, Boston-based mystery writer Robert B Parker sets an action sequence on the bridge. Early in the scene, Spenser describes the Smoot markings, and later, uses them to describe the action:

"There was another gunshot from five smoots away. I had my gun out and was running toward the Olds when I heard the MG take off with its tires squealing."
