Hfjfjdjfjceijfjon Digital Needle: Ripping vinyl records with a scanner (2013)

Stero channels aren't encoded in the depth and radial axes. They're encoded in the same plane, but rotated 45 degrees, so a mono record player (depth only) plays a balanced sum of each channel.

Edit: mono is radial only, not depth.

My understanding is that the first amendment prohibits federal and state governments (and therefore public schools) from placing restrictions on free speech in the first place. Therefore, parts of the code of conduct are unconstitutional and so unenforceable.

Hfjfjdjfjceijfjon New proof reveals that graphs with no pentagons are fundamentally different

There's a conjecture about graphs, and the conjecture was proven true for a new specific case. So we still don't know whether the conjecture is true in general.

For understanding the conjecture itself, I think the mathematical description is the easier to comprehend than any analogy. See the intro of the Erdős–Hajnal conjecture Wikipedia article[1]. Graphs are pretty intuitive mathematical structures and the description of the conjecture only uses basic graph structures. Although maybe I'm just not clever enough to come up with a suitable analogy.
