I fail to see how the fact scholars and other educated people knew the Earth is round means he couldn't have difficulty getting sponsorship because of that.

Because it wasn't just scholars - ''everyone'' knew that the world was a sphere. Sailors, for example, took the monumental task of noticing that when objects appeared in the distance, they seemed to "rise up" over the horizon (hence the phrase). For that to happen, the sea (and by extension the rest of the world) had to be curved.<br />

Looking at the moon and at the earth's shadow during a lunar eclipse would probably make many realize the earth is round. [[User:Ghaller825|Ghaller825]] ([[User talk:Ghaller825|talk]]) 12:45, 23 August 2013 (UTC)<br />
:Unless "round" as in "circular", rather than "spherical". A disc-like Earth could give the same effect. A ''non-tidally-locked moon'' would have been an interesting thing for early understanding of the universe, as it would have shown a clearly spherical ball rotating and let the layperson imagine sphericality under their own feet a lot easier in their own childhood, thus flat-earthing would have been culturally invalid, not just lazy/unthinking. Whether or not farmers 'knew'/cared/were-told-by-the-church that the world was flat isn't really relevent on the scale of farming where you need to worry more about localised hills on your land than global curvature on its actual order of magnitude. Of course, in the absence of any other clues you tend to think of everything as flat as your (crudely worked) kitchen tabletop by default.

I am not sure what people knew and what they believed in earlier times. For example: {{w|M-Theory}} says that the space we live in has 11 dimensions. Assuming this is correct, what will people in 500 years say about us? Did we know it or did we not? Could we have expected what will hit us in a couple of years from out of one of the dimensions that we do not visually perceive?<br />
To apply this to the quesion of whether they knew that the world was round: There is a {{w|Deep-sea_exploration#Milestones_of_deep_sea_exploration|story}} about Magellan (who certainly believed that the world was round because he tried to sail around it): He tried to measure the depth of the ocean with a 700m long rope. When the rope failed to reach the bottom, he concluded that the ocean was infinitely deep. Now how can a round object with a finite perimeter have and infinite radius? (I realize that wikipedia does not give any sources for the story and its origin is somewhat obscure, someone translated the story from the German wikipedia in July 2011; in the German wikipedia it had first appeared in 2006, but the story was around on German language websites since at least [http://www.scinexx.de/dossier-detail-40-11.html 2000]; I have no idea where it originally comes from, but it would be interesting to have a look at Magellan's ship's log if it had such a thing.) <br />

:You suppose that the round earth is imbedded in flat 3-dimensional space. If it were’nt, you could easily have infinitely deep oceans. Maybe Magellan was way ahead of his time by thinking in non-Euclidean categories.<br />
:(Explanation for non-mathematicians: Draw a circle – it surely has a finite radius, but if you measure the depth perpendicular to the sheet of paper, you could go infinitely deep. Now apply this to a round sphere and measure perpendicular to the 3D space you put it in.)<br />

::Your example fails. Magellan sailed in ship with keel pointing in the direction of the depth he tried to measure. His success depended on the fact that earth is round IN THAT DIMENSION.

{{incomplete|1253: Exoplanet Names}}<br />
<br />
On the 14th of August, the {{w|International Astronomical Union}} (IAU) [http://www.iau.org/science/news/179/ issued a document] about public naming of astronomical objects. It stated, "IAU fully supports the involvement of the general public, whether directly or through an independent organised vote, in the naming of planetary satellites, newly discovered planets, and their host stars.". It also contained, amongst other things, guidelines that suggested names should meet. These include stipulations such as "16 characters or less", "preferably one word", being "pronounceable (in as many languages as possible)", "not too similar to an existing name of an astronomical object", avoiding commercial names, and being "respectful of intellectual property". If we go down the list, we can see that many of Randall's suggestions do indeed violate the guidelines. Which is probably part of the joke.<br />
<br />
The document also states that suggestions may be sent to the email mentioned in the title text.<br />

Yes. And also why 2007? Not like him to pick a random year. Was it something to do with the new laser classification and warning/labeling regulations that went into place that year? (http://en.wikipedia.org/wiki/Laser_safety){{unsigned|Drjoe047}}<br />

<br />
I don't think that the explanation needs to include the description of Black Hat. He has his own page. Regarding his desire not to blind people, he's about to shine a laser in the police officers' eyes. He has no problem blinding people. In addition, I don't think the title text is ironic. Black Hat is a hacker. He's always embraced technology. He just embraces it his way.{{unsigned|Theo}}<br />

"The best defense is an discriminate offense." Might this be a play on the idiom "The best defense is a good offense"? The "indiscriminate" part strongly reminds me of NSA's justification that their massive surveillance program was not warrantless search & seizure ''because'' it's indiscriminate, i.e. no one person is targeted. Kind of like in this comic, where the device automatically targets any nearby Glass user but no one user(s) in particular.

What happens to time, when the world ends? It is a 10-day-forecast. That coincides with 10 image frames. We have the days of the week at the bottom of the frames, which are an independent scale, because there is more than one frame for Tuesday. Interpretation/Assumption: 10 days (the forecast) is subjective for the people being in each location (here: ZIP code). Days of week and generally dates are a global reference time. So in these hells time locally stretches for eternity and this day will never end. But from an outside view time goes on normally.<br />
Megan says they are all like that. That does not sound like it would be a special occasion to be there, when the world ends, or having found a ZIP number, where the world ends some days from now. Possible solution: Like a function with several poles the world could end at every location with negative ZIP about every week.

<div>WOW. When I first read the comic, I assumed it was making an analogy to current countries. Like ones that have been invaded because of their oil reserves. When I saw the image-text, my thought was "We can destroy time like we've destroyed these countries." The above explanation makes a lot more sense. [[Special:Contributions/76.106.251.87|76.106.251.87]] 06:17, 27 March 2013 (UTC)<br />
: I don't think there's a distinction. "If history has taught us anything, we can use that information to destroy it". If you destroy the country in the past, then you 'destroy' that timeline of history. (Of course, current consensus seems to be that you'd branch off into a new timeline and both will exist in parallel universes, but nonetheless - to the antagonist - it could well count as a destruction.

With public key systems like PGP you need the public key of the other person to verify the authenticity of the message. Most people do not use PGP or do not know how it works or are just lazy. Some of those are convinced enough just by the outer looks of a signed email: The starting block and the jumbled chars at the end. It is like being impressed by a signature per se in real life without knowing what the one of the person you write to looks like. I think the allusion to pretty good is coincidental.
