The sequel to Postergasm I, here I drop var­i­ous images of var­i­ous things for var­i­ous pur­poses. As with the first post the high-​​res ver­sions are opti­mized to print on an 11 x 17 sheet — not exactly movie-​​poster size, but large enough to be noticeable.

After the fold, mis­cel­la­neous posters along with descrip­tions. Enjoy!

For starters we have the elec­tro­mag­netic spec­trum. This is actu­ally a cut/​copy/​paste job of some­thing orig­i­nally done in Canada. The graph­ics were the biggest rea­son I used it, though even­tu­ally I think I’ll replace it with some­thing larger and with bet­ter resolution.

Every once in a while you’ll hear some­one claim that they have a mys­ti­cal power that uses an energy “unknown to sci­ence”. The elec­tro­mag­netic spec­trum calls bullshit.

The EM spec­trum is one of the ways we know there’s no such thing as chi energy, or the stuff that Reiki is sup­posed to work with — there are no gaps in the spec­trum wherein some kind of spooky action-​​at-​​a-​​distance energy might be found.

Next we have some mosaics from HST. The first one com­bines the spec­tac­u­lar imagery of an erupt­ing star with a hell of a fine shot of M31, the large spi­ral galaxy in Andromeda.

This sec­ond mosaic com­bines the Crab neb­ula (a super­nova rem­nant) with a dense clus­ter of galax­ies — in Hercules, if mem­ory serves. In the lower image, almost every object is a galaxy. Think about that.

The penul­ti­mate image is a famous one — the peri­odic table of the ele­ments, graph­i­cally. Each ele­ment is pre­sented as a photo object, not sim­ply as a dry list of num­bers indi­cat­ing atomic weight and so on.

The PTE is how we know there aren’t “unknown met­als” or sim­i­lar silli­ness from SF (as in, “The alien spaceship’s hull is made of an alloy com­pletely unknown to us!”). As with the EM spec­trum, there’s no room for unknown ele­ments to exist, not even in the transuran­ics. (This one is a JPEG; right-​​click to open it full-​​size in another window.)

Finally, the poster that began it all — some­thing from the Depression-​​era Works Progress Administration advis­ing New York res­i­dents to keep their liv­ing areas clean.

This poster is great from the ironic per­spec­tive — the idea of blam­ing ten­e­ment res­i­dents for the squalor in which they live, rather than the ruinous rent they’re charged or their land­lords’ unwill­ing­ness to take on main­te­nance, is clas­sic Voice of Privilege.

And of course, for some­thing to be hung up in a kid’s room, it’s just ideal.
