And if you are in fact a map geek, one of the tiniest changes on the map above may very well be one of the first discrepancies you notice. You might even question if it’s too small to show up at this resolution. It’s not too small.

Answers to the MIT Campus Scavenger Hunt

This post contains the answers to the MIT scavenger hunt I posted 40 months ago, excepting items in the 16 advanced item expansion known as the “Navigator’s Quest”.

I decided to end this due to changes that have occurred to MIT’s campus, the rate of which has been much speedier than I could have imagined 40 months ago. Buildings have been demolished, buildings have been built, buildings have been renovated, stuff has moved around, and permissions to various locations have changed such that original foundational ideas of the hunt could no longer hold. The Picture Scavenger Hunt, on the other hand, I still plan to run indefinitely, and it now has an established mechanism for pictures that become outdated.

In any case, congratulations to jakobw for the most items found during the duration this hunt was up.

As for the answers, long story short:

I decided to not chart locations that are answers to 39 here on a post on the internet. Ask me in real life for an answer to 39.

There are of course probably many more locations that several of these items can be found at than plotted in the map above.

Notes:

For item 1, solidly shaded buildings have the floor numbered 0 aligned with the ground. I also accepted buildings just outlined in the map above, though, as those are cases where ground is between floors numbered 0 and 1, but the floor numbered 0 is closer to the ground level than the floor numbered 1.

For item 8, Senior House was my original intended item. When I was designing the hunt, I momentarily forgot about graduate dorms when writing this item. I was later informed that at least Edgerton House among the graduate dorms have both A/C and elevators. Eventually, Senior House closed, but Edgerton House does still remain, so this item had an answer through the end of this hunt, despite this not being true of the set I was originally thinking of.

I parenthesized the Building 8 answer for item 9, even though I accepted it, because Building 1 is a case where the building is the fairly indisputable central home of a course, whereas Course 8 has substantial portions outside Building 8.

For item 20, there’s many tiny buildings that satisfy the item that I did not bother to mark on the map above. Probably my favorite case of this is Building W55, whose bottom doesn’t even touch the ground. (I was actually fairly sad they did not number its singular floor 2, so that MIT could have the amusing feature of containing a building whose lowest floor is numbered 2.) Of course, Building W55 hadn’t been built yet when I published this hunt. Building 34’s lowest floor is in fact 1 because what lies underneath it is actually not grouped with 34. This is in fact the reason for one of the answers to item 33.

Item 21: the Pharos color printer is in W20-575. This is a quite useful thing to know as an MIT student. When I wrote this hunt, though, the Pharos color printer was in 12-182, a room that no longer exists.

Item 24: the elevator services floors 4, 5, and 6. Without additional permissions, though, travel is restricted to oscillating between 4 and 6.

Southern Cambridge: An Ingress Territories Map

I made an attempt at depicting the southern half of Cambridge, MA in a map showing territorial control in Ingress, pointing out areas well controlled by one faction, like Cambridgeport (an Enlightened stronghold) and West MIT (a Resistance stronghold), also highlighting fronts and battlegrounds where control frequently shifts and action is relatively fast.

Well, in my head it was a lot cooler than it turned out. Perhaps with symbols crafted with more nuance this could look more like a battle map.

The Unavoidability of Red

In a recent referendum, Mauritania voted to add red stripes to their yellow-and-green flag. This means Mauritania has joined the vast majority of countries that have decided that red should be one of the colors on their flag. How vast is this majority? This vast.

No other general category of color (green, yellow, white, etc.) comes close to red’s dominance in prevalence among countries’ flags. A lot of nations find important symbolism in the color red, often representing the blood of those that have died for their country, revolution, courage, or valor, among other meanings.

In fact, if you look at the map above, you’d find that among countries with at least one land border, you cannot avoid either the country you’re in or a country you border having red in their flag if you include maroon as a red. If you exclude maroon, you can achieve this in Uruguay or Qatar.

Note that I have colored non-sovereign countries or territories in the map above according to the flag of the sovereign country that owns the land. If one considers the flags of these regions instead, there will be a few additional instances of flags without red, like Curaçao, Tokelau, and Macau.
