- ⭐️ 🕵🏼 🎥 Very very good, chilling video on privacy. Also worth noting that it was produced by the Financial Times. We know what you did during lockdown. “And that’s why the data knows best. And that’s why we must hand ourselves over to it. As emotional beings we are simply unable to measure that equivalence ourselves. So your audit trail will enter the system, and an automated verdict delivered to you in due course.”
- 🇧🇷 🤩 🎥 MIT Senseable City Lab maps Brazilian favela with handheld 3D-scanners. “Called Favelas 4D, the project uses point cloud data from handheld LiDAR (Light Detection and Ranging) scans in order to study the form of Rocinha, a favela in Rio de Janeiro. The low-income urban settlements have complex structures that are built by their inhabitants over time.” (Via Target_is_New.)
- 🤯 🌳 Some tree crazyness in this 🧵. This is called inosculation: when branches or roots of different trees are in prolonged intimate contact, they often abrade each other, exposing their inner tissues, which may eventually fuse. It’s not so much one tree feeding another as the formation of a new hybrid organism.
- 🇫🇷 🗺 😍 Blog in French but the goals and the maps are very much in the Sentiers wheelhouse and there’s lots to see, even if you don’t speak it. Kartokobri – cartographies imaginaires. “I draw maps and use them as supports to formalize readings of the world, starting from the idea that a map can tell an infinity of things seen, lived, told, understood and especially perhaps, misunderstood. Through them, I try to question facts, to develop stories, to fix memories, by diverting lines, contours, toponymies.”
- 🤯 🔭 The Final Border Humanity Will Never Cross. “This expansion means that there is a cosmological horizon around us. Everything beyond it, is traveling faster, relative to us, than the speed of light. So everything that passes the horizon, is irretrievably out of reach forever and we will never be able to interact with it again. ”
- 🔋 💩 Millions of electric cars are coming. What happens to all the dead batteries? “[W]hen the battery comes to the end of its life, its green benefits fade. If it ends up in a landfill, its cells can release problematic toxins, including heavy metals. And recycling the battery can be a hazardous business, warns materials scientist Dana Thompson of the University of Leicester. Cut too deep into a Tesla cell, or in the wrong place, and it can short-circuit, combust, and release toxic fumes.”
- 🌌 New dark matter map reveals cosmic mystery. “An international team of researchers has created the largest and most detailed map of the distribution of so-called dark matter in the Universe. The results are a surprise because they show that it is slightly smoother and more spread out than the current best theories predict. The observation appears to stray from Einstein’s theory of general relativity - posing a conundrum for researchers.”
