DAY 20: A Wilhelm Scream - Ruiner. 2nd press on purple mix /1000
Such a good band and such a good album. Considering the 1st press goes for $150 on eBay, I’m pretty stoked this came out.
Monday May 20 @ 06:33pmJupiter’s moon Io, photographed by Voyager 2, 10 July 1979.
The end of this blog’s Io-thon follows on from yesterday’s post. The photos used in this gif were taken with longer exposures than yesterday’s, so there is a better contrast between Io and the background. Two volcanic eruptions are clearly visible in the top-left: I think that they are from Amirani and Maui. There’s also an eruption on the right-hand side, but as its only lit by reflected light from Jupiter, it requires a lot of brightening to see (NASA’s photojournal shows it here).
You can also see a volcano in the south, tall enough to stay in sunlight even as the surrounding areas fall into darkness.
Yesterday I mentioned the bright spot glinting near the equator. I asked Jason Perry (who used to write an Io blog) about it on Twitter and he said that it “looks like specular reflection off of glassy, cooled lava near Hi’iaka Patera.” So there you go.
It scares the shit out of me that I’m not going to be any good at Astronomy. I’m still at that point where I’m uncontrollably naive enough to think I can do most things without REALLY committing myself, and at the first site of serious mathematics and science I fear that I’m either going to bail or fail.
Which sucks, because I’m really interested in what I’ve seen so far, and I’m eager to learn more.
If I won the lottery I actually think the first thing I would do is buy a ticket to the Himalayas and climb Mount Everest. Doing so after sending my ass into space would just make it insignificant.
On a side note my Nan thinks climbing Everest is “Easy” because they’ve put “Ladders everywhere”. Okay.
I doodled a thing. [x]
The Only Known Photograph of Einstein Deriving his Famous E=mc2 Equation
At a public lecture in Pittsburgh in 1934, four hundred lucky students were privy to a lecture by Albert Einstein, in which the great man mathematically derived his famous mass-energy equivalence equation: E=mc2. What you see above is a photo from that lecture, and what is thought to be the only surviving photo that shows Einstein working on that derivation.
The photo was pulled from a halftone newspaper clipping by David Topper and Dwight Vincent of the University of Winnipeg, who discovered it in 2007. Sadly, everything is a bit fuzzy so you can’t really make out the famed equation itself. And even though the original article had a crisp picture of Einstein posing next to one of his blackboards, he’s next to the wrong one.
Here’s a closer look at the man and the math. If you look closely, you’ll see the mass-energy equivalence in the lower left hand corner of the blackboard on the right:
Fortunately, Topper and Vincent managed to take the blurry photo and reproduce both blackboards in their original paper. Here’s the math behind the magic, the derivation of mass-energy equivalence as presented by Albert Einstein.
In case you’re wondering why the famous equation says Δ

Alex is like my fitness goal
It would be cool to be Superman or someone like Doctor Manhattan. Being able to visit other star systems, planets, galaxies… being able to walk on the surface of a star or at the bottom of the Mariana trench. That the kinda stuff my dreams are made of.
