The Wallace-Bolyai-Gerwien theorem shows that any two polygons with equal area must admit a dissection into finitely many pieces where one is allowed to arbitrarily rotate and translate the pieces to go from one polygon to the other. The problem about whether a hinged dissection exists remained open until 2007. You can read the paper here, which presents a method which always works to find a hinged dissection.”

for me, tao lin’s taipei wasn’t all that enjoyable or rewarding (compared to the sustained attention I gave it). occasionally I found paul’s/lin’s thoughts/words particularly insightful/well-written, but the majority of the text was off-putting/uninteresting (to me). I know lin just has a different style/approach to his writing, and I tried to frame my reading as necessary to appreciate it, but I think I just got bogged down by the flatness of the characters. also doesn’t help that I just recently read infinite jest, ie. it’s now difficult not to compare lin’s (or any author’s) writing to wallace’s.
edit: bret easton ellis’s tweet about taipei is pretty much on point.
While there is a lot of appropriate rage about Ferguson right now, the killing of John Crawford, III is getting less attention than it deserves. I put Shaun King’s tweets and history lesson on the matter in chronological order for easier consumption.
You really should be following Shaun King on Twitter.
someone made a really good point in the commentary of a post once which basically boiled down to the fact that james and lily’s patronuses are complements of each other (stag / doe) as opposed to snape and lily’s (doe / doe) which just goes to show how love and obsession are not the same thing at all thank u for ur time
As much as I agree that Snape’s feelings for Lily were messed up, this still pisses me the fuck off. It’s way too close to the idea that same-sex love is narcissistic and obsessive as opposed to heterosexual love which is meaningful and pure and real.

How far is a light-year?
If you do the math, one light-year is about 9.5 trillion kilometres (5.88 trillion miles). But how can one comprehend and visualise such a huge number? Bruce McClure of Earthsky.org reveals an ingenious way to visualise the said number by way of mathematical coincidence.
It turns out that the number of inches in a mile is equal to the number of astronomical units in a light-year. One astronomical unit is the average distance between the sun and the earth, which amounts to 150 million kilometres or 93 million miles.
