For those not up to speed with the latest AI jargon, I hope to clarify some things:
Every time a company promises a revolutionary “AI” product, they just exploit cheap labor from India.
Do you think it’s an overstatement to call these concentration camps? Read @AndreaPitzer
Judging by the pictures in Arjen's book I think it must be
My take: clothes are to be used until they rip apart.
Happy birthday to #astronomer Henrietta Swan Leavitt (1868-1921) who set the scale of our Universe. My portrait of Leavitt is printed in silvery lavender ink on Japanese kozo (or mulberry paper). Behind her is a line showing stellar luminosity (capital L with subscript sun-symbol, a circle with a dot) as a function of time (t). She is printed over constellations in gold (Cepheus, Cassiopeia, Draco, 🧵

accomplishment for which she received little recognition during her lifetime.
Cepheid variables are a class of pulsating star. They are named for the star Delta Cephei in the Cepheus constellation. The relationship between a Cepheid variable’s luminosity and pulsation period is quite precise. It had not been obvious to tell whether a star was dim because it was less luminous, or whether it was merely further away. 🧵3/4
Swan Leavitt’s discovery lets astronomers use Cepheids as “standard candles”. They allow astronomers to determine distances to celestial objects and form the foundation of the Extragalactic Distance Scale.

@trrektor what?
This makes no sense to me. Also, not a bro.
@trrektor Absolutely not.
If you’re going to go around chastising strangers for their artistic expression at least have the integrity to apologize when it’s made clear to you that you misunderstood and you’ve mistaken shading in a relief print for facial tattoos (which would have been a weird and irrelevant addition to my portrait of a American astronomer). The thing you’re criticizing never happened.
