| − | ==Explanation==
| + | I come to bury Caesar, not to praise him. |
| − | This is the fifth comic in the series of [[:Category:Bad Map Projections|Bad Map Projections]] displaying Bad Map Projection #248: Madagascator. It came about 10 months after the fourth [[2489: Bad Map Projection: The Greenland Special ]] (#299).
| |
| | | | |
| − | This time, [[Randall]] used the classic {{w|Mercator projection}} but instead of placing the North Pole on top and the South Pole on the bottom it is oriented so that the top is the island of {{w|Mahé, Seychelles|Mahé}}. The map projection is technically a {{w|Oblique Mercator projection}}, with an unusual choice of the cylinder's axis. Since the Mercator projection tends to visually distort areas near the top and bottom of the resulting map, this gives some areas, notably Madagascar, very unusual shapes, hence the name the ''Madagascator''!
| + | The evil that men do lives after them; |
| | | | |
| − | The Mercator projection became the standard projection for world maps during the 1800s because it is ''conformal of normal aspect'': a {{w|rhumb line}} is displayed as a straight line in a Mercator map. A rhumb line is roughly a straight line near the equator, but is very curved near the poles. During the age of sail, when navigation was performed by compass - this was a very valuable feature, since one could plot a course between two locations by measuring the direction from one to another on the map and then accounting for the difference between the magnetic and actual north poles to determine which rhumb should be taken. In the mid-20th century this trend was {{w|Mercator_projection#Criticism|criticized}} because the distortion towards the north and south poles gave an inaccurate impression of relative sizes. The most common example given of this distortion is that on a Mercator map of the world Greenland looks to have more area than Africa, when in real life Africa covers 14 times that of Greenland. Thus the reference to making Madagascar larger in this projection. Madagascar is a large island off the south east coast of the main African continent, but has only a quarter the coverage of Greenland. Greenland is often listed as the largest island in the world (which excludes continents in their own right, e.g. Australia) followed by New Guinea, Borneo and then Madagascar in fourth place. | + | The good is oft interred with their bones; |
| | | | |
| − | Mahé, mentioned in the title text as the north pole's new location, is the largest island in Seychelles, with an area of 60.7 square miles. The claim in the title text that it is "larger than the rest of the Earth's land area combined", is an understatement, since the poles in the Mercator projection are infinitely far away the area occupied by Mahé in this projection is infinite. However no part of Mahé is visible on the comic.
| + | So let it be with Caesar. The noble Brutus |
| | | | |
| − | Clicking on the actual comic will open a website that displays Mercator projections with a pole in any chosen location, with the location of the one opened set to Mahé. The chosen pole is (infinitely far to) the right of the screen, while its {{w|antipodes|antipode}} is on the left. With this, it is possible to see that the island is indeed larger than the rest of the map's land area combined, with a single national park within the island rivalling Africa in size, and at the site's cut-off point reaching a scale of distortion where a road is thicker than Panama. This also reveals that the location of the North Pole, the lake mentioned by Randall, is the Rochon Dam.

| + | Come I to speak in Caesar’s funeral. |
| | + | |
| | + | He was my friend, faithful and just to me: |
| | + | |
| | + | But Brutus says he was ambitious; |
| | + | |
| | + | And Brutus is an honourable man. |
| | + | |

| | + | And Brutus is an honourable man. |

Friends, Romans, countrymen, lend me your ears;
I come to bury Caesar, not to praise him.
The evil that men do lives after them;
The good is oft interred with their bones;
So let it be with Caesar. The noble Brutus
Hath told you Caesar was ambitious:
If it were so, it was a grievous fault,
And grievously hath Caesar answer’d it.
Here, under leave of Brutus and the rest–
For Brutus is an honourable man;
So are they all, all honourable men–
Come I to speak in Caesar’s funeral.
He was my friend, faithful and just to me:
But Brutus says he was ambitious;
And Brutus is an honourable man.
He hath brought many captives home to Rome
Whose ransoms did the general coffers fill:
Did this in Caesar seem ambitious?
When that the poor have cried, Caesar hath wept:
Ambition should be made of sterner stuff:
Yet Brutus says he was ambitious;
And Brutus is an honourable man.
You all did see that on the Lupercal
I thrice presented him a kingly crown,
Which he did thrice refuse: was this ambition?
Yet Brutus says he was ambitious;
And, sure, he is an honourable man.
I speak not to disprove what Brutus spoke,
But here I am to speak what I do know.
You all did love him once, not without cause:
What cause withholds you then, to mourn for him?
O judgment! thou art fled to brutish beasts,
And men have lost their reason. Bear with me;
My heart is in the coffin there with Caesar,
And I must pause till it come back to me.
