Sorry if you see this behind-the-scenes as "still processing". It's a 4K video and so seems to be taking ages. But the main video is definitely up.

From my video "The bridge which is measured in smoots".

FYI you're right about the graduating years; those marks were from the 2015, 2016, and 2017 classes. (And the 333 1/3 is an "unsanctioned" mark from the 3rd floor of one of the dorms.)

How many Smoots tall is Matt? Then we can have an unofficial Parker designation for the bridge, too.

Thomas Robert Wade

According to Google, I am1.1194029850746272 Smoots tall.

If the Parker was a unit of measurement, would a squared Parker be negative? Now that's what I'd call a complex system.

Matt Parker

It's ok: I'm back in the UK now and have my replacement phone. I'll try to do more 4K videos.

Matt Parker

That would have been great, but I'm back home in England now. I was sadly only in Cambridge (USA) for two days.

Matt Parker

Thanks for letting me know! I half-remembered that classes marked their years. I had no idea about the 333 point though.

Matt Parker

Everything I do is complex! (As in: half of it is imaginary.)

Jochen Römling

How did you record the audio? My first guess would have been a lav-mic into the phone, but: there was no phone.

Doug Jones

Every day I find myself happy that I decided to back you. The behind the scenes footage is just as interesting as the videos. I'll definitely need to check out that bridge when I make it out to Boston next year. (Dropping my daughter off at school)

Doug Jones

I'm guessing lav-mic into the GoPro. ;)

Sjoerd Wennekes

I like these full long videos you make, I don't really care for the abridged versions. (Sorry, I couldn't help myself)

Matt Parker

Thankfully I have an old iphone4 I carry around just to record audio. So I had a lav mic going in to that in my pocket. I use my main phone for audio sometimes but if I'm using it to film, I need a back-up audio-recording phone.

Matt Parker

Glad you're enjoying the bonus footage! I'm finding it a surprising amount of fun to make. It's really low-pressure to just do one long rambling take. I hope your daughter enjoys studying there.

Patrick W. Gilmore

Need to give us more warning! I would have happily treated you & your wife to a nice dinner with some very fine single malt. Anyway, keep up the great videos. Thank you!

Matt Parker

Sorry! It was a flying visit of Boston but we'll hopefully be back some time.
