Shit I Find Interesting-Chat

-Removing iron from wood -Freeze water -Solid state to a gas state, skipping liquid state -Liquid state (as it dries) pulls all the cells walls together. Causes wood to shrink and collapse the surface tension of the water - pulling the cell walls in. Ship in France

Ferro arm Bugs

“Loose wire” Final screw removed, removed cover, a pile of ants fell out Re-creating the ship exactly how it was in the ground when it was dug up -if wood has changed shape Ship lines -loft the shape of the ship with a series of lines that project the space through the different dimensions Extract original lines of the ship. Replicate those to get the rest of the ship.

Radio astronomy Hydrogen’s signal Aug 15, 1977 -narrow band signal -1420 mega hertz -lasted for 72 seconds -30 times the strength of the background noise -known as the Wow signal -signal never came back

To send a message that carries information, you need change. Humans and animal signals Patterns of change

Random events The rarest outcome is when the ball goes the same direction every time. There is only one path that does that. Most paths lead to the middle. Water -Wave -Trough - the tails of the shape Gaussian distribution Random events having an impact on the next outcome

Same basic shape - rounded convex curve. A fingerprint seen across nature. Detect a mind through what it communicates -Language Linguist - George Zipf Concave curve Straight line Power law Universal pattern Language pattern Noise pattern Nature’s trick up its sleeve Earthquakes Any system that accumulates stress and releases it (ie lightning strikes), produce this shape. Magnetar Zipf’s law - not enough to be the filter because nature can imitate it without a brain “We need a filter that nature cannot fake.”

Claude Shannon -measure sequences of symbols, pairs of symbols, triples, etc Plotting shows the slope gets steeper -keeps going, longer sequences The longer the sequence, the more predictable the next symbol becomes. Each symbol you know narrows what comes next. ..regardless of what language it is

The measure of surprise (Alice and Bob) Entropy changes as you look deeper into a signal Lawrence Doyle - filter for intelligence Naturally occurring symbols (that we know of) stay flat on the chart With “language”, it keeps dropping. More predictable. Only a mind produces this signature. Measurement -if it plunges, a mind was, potentially, behind its creation Mind -how could we understand what it’s saying?
