George Bush doing the ice bucket challenge thing is really unsettling to me because it’s all over my dashboard right now and I truly don’t understand why people on this website now seem to think of him as America’s goofy uncle that does bad paintings you do remember who he is right?
alanis: Clouds and shadows on Mars, photographed by Mars Express, 24th May 2012.
Between 28 and 36°S, 284°E, on the arc of highlands that surround the southeast Solis Planum. The crater split between the 2nd and 3rd images is Voeykov, about 75 km across, named for climatologist and geographer Alexander Ivanovich Voeykov (1842-1916). The small, deep crater toward bottom left of the 4th image is Los, named for a village of about 400 people in Gävleborg County, Sweden.
Composite of 3 visible light images for colour, and 5 monochrome images for animation. Colour is not balanced naturalistically, and the slightly psychedelic colours of the clouds are a result of mismatches between the images where the clouds have moved between exposures.

Signal Collection and Parabolic Reflectors
A reflector is a type of antenna that receives and focuses various types of signals. Reflectors have numerous applications, from satellite dishes and telescopes, to long-distance microphones and car headlights. One common feature of these examples is their parabolic shape, giving them the name parabolic reflectors.
It turns out that paraboloids are the perfect shape for focusing signals from distant sources. When pointed directly at the the incoming signal, a parabolic reflector (GIF 1) collects the signal to a single focal point, where a receiver, called a feed horn, is placed to collect the focused transmission.
In many applications, parabolic reflectors are too costly to produce, so spherical reflectors (GIF 2) are used instead. The disadvantage of spherical reflectors is that they have multiple focal points, and therefore produce blurry results.Mathematica code posted here.
This code is incredibly messy and I guarantee there’s a better way to calculate this. Please contact me if you have suggestions!
i talk a lot of shit for someone who can’t choose rude dialogue options in games because i’m scared of hurting a characters feelings

And I, infinitesimal being,
drunk with the starry
likeness, image of
felt myself a pure part
of the abyss,
I wheeled with the stars,
my heart broke loose on the wind.
