Why can't we combine Gall-Peters and Mercator together to create a perfect map that's both accurate to size and shape?

[Anonymous No.6683582]

why can't we have a 3d map readily available online period

[Anonymous No.6683598]

>>6683582
I don't know, it just seems extremely stupid to me we can't have a proper flat map.
I mean just look at how horrible Gall-Peters looks because it distorts shapes so horribly, but then Mercator distorts size the further away from the Equator you go until Antarctica becomes a monster.

How about Fuller projection?

Because there's no effective way of accurately mapping a sphere to a plane.

Its not possible in this universe. Its as fundamentally not possible as... Pi being what it is.

Why don't you just use a globe?

[Anonymous No.6684079]

>>6684053
Or a 2D simulation of one, or a book with like 20 degree rotations of a globe.

[Anonymous No.6684081]

I like it, at least.

>why can't we imbed an n-sphere into Euclidean (n-1) space without loss of information?

Anon, if you find a way, get back to us.

Actually, it's an n-ball. Regardless, it's still impossible to map from an r-dimensional space with no edges to an r-dimensional space with one edge and not lose any information on shape OR size.

[Anonymous No.6684279]

>>6684160
Naval Navigation is less important these days than accurate representation of locations and sizes of continents

What about Winkel tripel projection?

I would prefer the Mollweide projection because it's equal-area.
Rule of thumb: Greenland has about the area of the southern part of India (that extends into the Indian Ocean).

We can, it's called a globe

[Anonymous No.6685867]

People seriously wasted their careers making all their own globe maps? Seriously, how many do we fucking need?

sorry, thats hammer retroazimuthal back hemisphere.

how about hammer retroazimuthal front hemisphere

[Anonymous No.6686446]

>>6685867
Probably not as many as we have, but a few. You use different projections depending on what you are trying to display and analyze.

[Anonymous No.6686977]

Okay who added this stupid shit to the theorema egregium wiki page?

>An application of the Theorema Egregium is seen in a common pizza-eating strategy: A slice of pizza can be seen as a surface with constant Gaussian curvature 0. Gently bending a slice must then roughly maintain this curvature (assuming the bend is roughly a local isometry). If one bends a slice horizontally along a radius, non-zero principal curvatures are created along the bend, dictating that the other principal curvature at these points must be zero. This creates rigidity in the direction perpendicular to the fold, an attribute desirable when eating pizza, as it holds its shape long enough to be consumed without a mess.
