Here is the poster that Paco presented about what it is like to be an astrodog, Chapter IV. He presented it in the front of the room at a conference in Delaware some years ago.
The Brown Dwarf-Exoplanet Connection Conference (BDExoCon) at the University of Delaware, Newark, October 2019.
Paco, the astrodog on top of Parvi, an astronomical instrument in use at Palomar
Here is Paco, guarding PARVI, an instrument my team and I deployed and have now automated to understand what our solar system might look like from ~30 light years away. Paco is gone now, but he had true pride as our spokesdog for two projects. He had a paper published and went to Palomar 10 times.

26.09.2025 07:06 β π 2 π 0 π¬ 1 π 0We certainly can. The technology now is so far superior to the imaginings of the early zoning laws.
26.09.2025 06:39 β π 0 π 0 π¬ 0 π 0Normalize this to population. In 1914 when the first zoning laws in the world came into effect in Manhattan, more than 2 million people lived below 14th street. These data need context. Manhattan is only about 1.6M now. It should be well over 55M as the 1914 law suggested and imagined for the future
26.09.2025 06:38 β π 2 π 1 π¬ 0 π 0I am an amateur urbanist and futurist, but these numbers need to be normalized to the population. 50,000 new apartments or huts in outer boroughs is about 0.5% growth per capita. In a city where the occupancy rate is well over 99.5%, hundreds of times this level of development is needed. Up not out!
