Randall Munroe: "What If?" - Talks at Google

The comic consists of a flowchart depicting various ways to tell what era a map is from based on present country borders and land forms. While many of the options are very serious, a few bizarre options reference fictional maps Discworld , Narnia , and Tolkien's Middle-earth , or consider that seagulls, staplers, tubas, or breadboxes could be mistaken for a map. Randall also mentions US President Jimmy Carter being attacked by a giant swimming rabbit, an event previously referenced as one we must never forget in America. The flowchart, although probably effective in eventually identifying the production year of certain maps, is designed in a rather inefficient way, as some early distinctions are already on a very detailed level before some really important distinctions fictional or non-political map are made. This, of course, adds to the humorous tone of the comic. It is also hampered by several smaller or larger error see trivia , the biggest being a whole section on I that gives years in the range —, before I was built, and coming from a question that fixed the year range to —

To the north of this island is a smaller island called Photo Blogs. South of Diary Blogs, and off the southwest coast of Music blogs is a smaller island called Fandom Blogs.

There are other guides to finding the date of presentation of a globe of course, which may or may not pin the date down more precisely. Pault talk3 June UTC. Starting at the Istanbul Division, the Question Date Range no longer fits the definition at the top of the table, and now includes the effects of the Prior Date Range.

Istanbul has been the official name in Western languages since the s although it's been the native name sincealthough Western maps often referred to it as Constantinople as late as the s; on the flowchart, the choice of name appears to go with the s date.

It was renamed Tokyo which means "Eastern Capital" when it became the capital in Most English books around then would actually have called it "Tokei," the Chinese reading.

The name Tokyo didn't take off until Hepburn romanization was popularized in the s.

Mexico and before its independence, New Spain occupied the area modern-day Texas from around when the first permanent Spanish settlements were founded to the Texas Declaration of Independence in the comic apparently cited as the date — the land called "Texas" was only a small part of the modern-day state.

The Republic of Texas only lasted a decade and joined the US in The US? Spain occupied Florida as East Florida and West Florida but frankly they didn't actually want it — it was expensive to send people to settle it, and there wasn't much economic value in it. For some reason, the comic treats Florida as part of the US in ; see questions 7 and 8.

The Kingdom of Saudi Arabia was founded in It is the first modern state to exert control over the area it claims, which previously were controlled by various tribal leaders.

This resulted in the inconclusive Korean War. Jurisdiction over the island of Jan Mayen was given to Norway aroundand it officially joined in Note: Strictly speaking, it should be almost impossible to answer "Yes" to this question — the Ottoman Empire existed untilthe Soviet Union existed from toand North Korea from onwards, so by answering "No" to the previous three questions, the user has ruled out the entire period during which Norway has officially owned Jan Mayen, and almost the entire period it controlled it barring an extremely slim sliver of time between November 1, to December 28, The following questions ignore the previous ones East Germany only existed at the same time as the USSR, and Pakistan was founded later than North Korea, so both should have already been excluded — essentially, the Jan Mayen question reboots the test.

At this point, it is clear that the map in question is not a political map from any time. Therefore, the comic tries to determine whether it is a map of the Earth at all by asking if the continents are there.

A map of the Earth that does not label political regions must be a topological map; or, it can be a satellite image of the Earth.

As settlers made their way west, the prairie land in the Great Plains region was steadily replaced by farmland and ranches. By the s, most of the land had been converted to agricultural use, and the last of the prairie was largely obliterated by the Dust Bowls in the s.

The dividing lines correspond roughly to the three types of prairie: tallgrass prairie grew between the Mississippi and Indiana, mixed grass prairie covered Nebraska and other states on the th meridian westand shortgrass prairie covered the remaining area east of the Rocky Mountains.

The forest Mirkwood was called Greenwood the Great from its discovery by the Elves c. It was cleansed on 'March' 28, in the Third Age which ran for 3, yearsafter which it is called the Wood of Greenleaves.

Not a map of the Earth Yes: map of Narnia No: inconclusive Yes: map of Narnia Go to 38 No: not a map of the Earth Go to 42 Narnia Subbranch Note: This series contains seven books, whose original publication order does not match their chronological order. Questions in this subbranch concern whether the place referenced can be found in the map contained in each book, not in which books' time the place exists.

Therefore, places that exist in a book published later but is chronologically earlier than another book will not appear in the latter book, even if canonically they still exist in its time. Here are the seven books in their original publication order, which they will be referred to as. Calormen is a foreign empire in The Chronicles of Narnia. While it was indirectly referenced in the first three books, it was not included in maps until the later books in the series.

At this point, the map can only be a homemade map of some other fictional world. Although it might be a published map of another world, such as Pern, Oz or Mars but there isn't enough room for these options.

Since we have already done the "made it myself" part, we need to do the other parts too, albeit out of sequence. A homemade map Thank you! Now we are trying to guess something that is not a map. Makes sense to ask if it's something that bites, right? However, instead of asking further questions to narrow down the choices, the comic just gives a guess for each response. The comic guesses a breadbox itself as something about the same size as a breadbox.

It turns out Monday was Steve Waterman's birthday. His site has posters of his map, plus maybe the world's only Winkel Tripel-critiquing poetry. The comic is one large panel, with different types of map projections listed in two columns. Each listing has an illustration of that projection plus a short paragraph describing the individual who prefers that projection. What your favourite Map Projection says about you. Mercator [[A drawing of the Mercator projection is shown.

In this the world is distorted to fit into a perfect square, centred on Africa. Robinson [[A drawing of the Robinson projection is shown. Areas near the poles in this projection are fairly distorted, but the distortion is greatly reduced when moving toward the equator. You like coffee and enjoy the Beatles.

You think the Robinson is the best-looking projection, hands down. Winkel-Tripel [[The Winkel-Tripel projection is similar to the Robinson projection, with less distortion at the poles.

However the distortion at equivalent latitudes differs as the longitude varies. You're worried it's getting played out, and are thinking of switching to the Kavrayskiy.

You once left a party in disgust when a guest showed up wearing shoes with toes. Your favourite musical genre is "post-". Hobo-Dyer [[The Hobo-Dyer projection is a cylindrical projection resulting in significant latitudinal distortion.

The result is a rectangular image with the poles vertically compressed, and land near the equator stretched.
