Answer: THERE'S PLENTY OF ROOM AT THE BOTTOM

The ⊥IW.nano round had a peculiar unlocking structure. When solvers first opened the round, it was entitled ⊥IW.giga and the metapuzzle for that round—Rule of Three—was already solved. Solvers needed to determine that one of the puzzles in the round—Twins—was impossible to solve normally and must be backsolved from the meta. When this puzzle was backsolved, the website allowed solvers to “zoom in” to ⊥IW.kilo, a whole new round with Twins as the metapuzzle. Solvers then needed to repeat this process and backsolve a particular puzzle in ⊥IW.kilo to enter ⊥IW.milli. Finally, in ⊥IW.milli, solvers found that one of the individual puzzles was titled ⊥IW.nano. Backsolving ⊥IW.nano completed the entire round and fixed the ⊥IW.nano building.
The answer to this puzzle is a feeder to Level One—the metapuzzle of ⊥IW.milli. We know Level One has the answer LEGACY. As stated above, we must reverse-engineer how Level One worked and use that information to backsolve this puzzle.
The other answers in this round are:
CLOVER FOOD LAB INTERSTELLAR TRADE BUZZFEED THE SPICIEST MEMELORD SOUNDLINK
Indexing by the numbers listed on the meta page into the corresponding answers yields ONE.MI?—this can be completed to ONE.MIT, which clues the artwork associated with MIT.nano that contains the names of every known MIT affiliate from 1861 to 2020. This is confirmed by noting that the outer ring of the circle is the same color as the outer ring of the seal on One.MIT 2020.

At this point, we might realize that each of the answers corresponds to a well-known MIT alum (though the degree of well-known-ness varies greatly).
| Answer | Alum | Letter | Notes |
|---|---|---|---|
| CLOVER FOOD LAB | Ayr Muir | L | Muir founded Clover Food Lab. |
| INTERSTELLAR TRADE | Paul Krugman | E | Krugman wrote a famous paper about interstellar trade. |
| BUZZFEED | Jonah Peretti | G | Peretti co-founded Buzzfeed. |
| THE SPICIEST MEMELORD | Lillian Chin | A | Chin wrote down “Who is the spiciest memelord?” as her final response in the 2017 Jeopardy! College Championship. |
| SOUNDLINK | Amar Bose | C | SoundLink is a brand of portable speakers manufactured by the Bose corporation, which was founded by and named after Amar Bose. |

The One.MIT project built a website where you can look up the position of MIT affiliates’ names on the seal. Entering the above alumni on the website, we can confirm that they’re all present on One.MIT 2020.
One.MIT added the names of people who joined MIT between January and November 2020 in early 2021, which resulted in everyone's positions changing. As such, this puzzle is sadly no longer solvable.
Now we must determine how to extract the meta answer LEGACY. The seal includes the text MASSACHUSETTS INSTITUTE OF TECHNOLOGY and MENS ET MANUS in big letters, and the letters of LEGACY can be found in those phrases. A reasonable assumption is that we should use the arrows on the diagram on the meta page to point to the letters of LEGACY somehow.
All the arrows emanate from the center of the seal, but if we reposition each arrow so that its end starts at the position of a particular alum, it will point to the corresponding letter. For example, the arrow pointing towards the top left can be repositioned to point from Amar Bose’s position on the seal to the letter C.
All arrows except one are used to get from the five solvable puzzles’ answers to the letters L through C, leaving the shortest arrow pointing down and to the right.
Since there is only one remaining arrow and one unique letter Y on the seal, we can determine the position of the missing MIT alum, but we still need to find the name there. The website allows you to zoom in on an arbitrary position and view the names at that location.
If we do so precisely, we’ll find that the name at the desired position is none other than RICHARD P FEYNMAN. This, however, is not the answer to the puzzle.
We’re looking for a word or phrase that is associated with Feynman that begins with the letter T and provides a satisfying response to the grad students who “don’t have enough space for their stuff.”
Scanning through Feynman’s Wikipedia page, we might notice the name of a famous talk he gave in 1959 that is associated with the conceptual beginnings of the field of nanotechnology, which should allay the grad students’ worries: THERE'S PLENTY OF ROOM AT THE BOTTOM.
