Math, cosmology, biology, geology, photography enthusiast and software engineer. They/them I'm not here to argue.

An empty starbucks cup held by a barista with the printed sticker saying "Vt Bl Islco E Drk." It is overly abbreviated from "Venti Blended Island Colada Energy Drink."
A 2cm faceted diamond sphere with slightly rounded edges. It's illuminated by a beam of white light that it scatters and diffracts into rainbow caustics on the floor. The background sunset is out of focus.
satellites are free-flying, the spacing is easily adjusted before launch, with upper bounds being imposed by the sizes of the teiescopes required at each end of the interferometer (which are constrained by the size of the launch vehicle's payload fairing) and the stability of the constellation orbit (larger constellations are more sensitive to the gravitational effects of other planets, limiting the mission lifetime). Another length-dependent factor which must be compensated for is the "point- ahead angle" between the incoming and outgoing laser beams; the telescope must receive its incoming beam from where its partner was a few seconds ago, but send its outgoing beam to where its partner will be a few seconds from now.
Starstruck. A stunning snapshot in time. The Artemis II crew captured this breathtaking photo of our galaxy, the Milky Way. The Milky Way’s elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Spanning more than 100,000 light-years, Earth is located along one of the galaxy’s spiral arms, about halfway from the center. Credit: NASA

Of course, these algorithms are constrained in other ways-random generators simply aren't good enough to do what people can do with an actual deck. But even the most skillful human dealer cannot provide a perfect hand every time.
The nuclear initiative means that NASA will continue to have a hand in nuclear development even after the Pentagon's recent cancellation of a joint program on nuclear-powered rocket engines. " Well, the budget did not prioritize nuclear propulsion, that wasn't because nuclear propulsion isn't seen as a non-worthy technology," the NASA official said.
" we can confirm that Google deepmind has reached the much desired milestone, earning 35 out of a possible 42 points - a gold medal score. Their solutions were astonishing in many respects. IMO graders found them to be clear, precise, and most of them easy to follow." - IMO President Prof. Dr. Gregor Dolinar This achievement is a significant advance over last year's breakthrough of results. At imo 2024, AlphaGeometry and AlphaProof required experts to first translate problems from natural language into domain specific languages, such as Lean, and vice versa for the proofs. It also took 2 to 3 days of computation. This year, our advanced Gemini model operated end-to-end in natural language, producing rigorous mathematical proofs directly from the official problem descriptions - all within the 4.5 hour competition time limit.
