[UPDATE (2021-02-16 14:46:07 UTC): mea culpa! Corrected temperature comparison of Boca Chica vs. Chicago. Also, noted and corrected temperature error in quoted text. --martyb]Boca Chica, Texas is located at the southernmost point in Texas and is where SpaceX builds and launches its next-generation Starship orbital rockets. At 2:30 PM local time, the predicted high temperature for the day was 17°F (-8.3°C) which was colder than nearly as cold as Chicago, Illinois where the day's high temperature was predicted to reach 15°F (-9.4°C) .upstart writes in with an IRC submission:Millions without power in Texas as snow storm slams US:

hubie writes:Wind speed is something that is hard to qualitatively describe from person to person. One person's playful breeze is another's biting annoyance. For a very long time this was a problem in the maritime domain so a couple of centuries ago Francis Beaufort came up with the Beaufort Scale. This scale ties wind speed to objective observations. It was first applied to sea state, but it was later extended for observations on land.There is a research field growing up around the idea of "social sensing", where social media platforms, particularly Twitter, can be used for real-time detection and tracking of natural events, such as earthquakes, forest fires, air quality, etc. A group of researchers from the University of Exeter have established a social Beaufort scale using Twitter. They looked at 110k weather-related tweets in the UK spanning two years to see if they could detect wind-related effects and estimate the wind magnitudes by looking at the language and emojis used, similar to what is done with the Beaufort scale (well, except for the emojis). They found that a simple text classifier can be used to detect high-wind events fairly accurately and the severity of these events can be inferred by considering the tweet volume.Journal Reference:

hubie writes:Biological swarms are fascinating and even mesmerizing things to watch, as hundreds or even thousands of individual entities behave in a manner such that their collective behavior can act almost as a great organism that responds to its immediate environment. A large and diverse number of organisms exhibit collective behavior, so it is generally assumed that this permits tasks to be achieved that are well beyond what a single individual can achieve while operating without the need for top-down control. There has long been significant interest in understanding how to exploit this in engineered systems such as drone or bot swarms.The challenge in understanding collective behavior is that one normally has to assume a priori a mathematical model to simulate, which means trying to extract rules for how the individual entities interact, and their relative interactions can change depending upon their changing environment. A new paper studied swarms of midges and they argued the case for not worrying about the individual particles, but treating it as a thermodynamics problem.
