    Peter Godfrey-Smith discusses this topic at length in his recent-ish book Metazoa and uses observations of insects and other invertebrates to argue, compellingly in my opinion, tha…

    The US put a fission reactor in space too. They did it first, in fact: https://en.wikipedia.org/wiki/SNAP-10A Edit: it’s apparently still there and will be for a long time (!) albe…

    The other pro is cost: cameras are much, much cheaper than LiDAR. Tesla is making the bet that they can close the performance gap between cameras and LiDAR faster than the cost of …

    Off-topic: in the photo lede at the top of the article, are the rescued merchant mariners wearing standard eye/ear protection or is something else going on? Based on how they are h…

    I think language acquisition provides a pretty compelling example of learning affecting the experience of qualia. When someone is learning to speak a foreign language, there is oft…

    David MacKay discusses this in Sustainable Energy Without the Hot Air . He concludes that, while it's on first glance appealing to want to use waste heat from power generation, hea…

    Louis de Broglie's dissertation [1] is mindblowing and quite cogent (at least in the English translation, but presumably in French too ...) 1. https://fondationlouisdebroglie.org/L…

    Max Welling's Kalman Filter tutorial [1] derives the smoother equations using pretty clear and easy to follow notation (and is a great resource generally). Briefly: you first run t…

    That doesn't pose an issue: the "observation model" of a Kalman filer allows for affine transformations (e.g. scale, rotation, and offset) between the sensor data and the "true" la…

    There are many ways to think about the Kalman filter. Here are a few that I like: * You can think of it as a Bayesian update process for linear Gaussian systems. That is: given a p…

    That's a bit of a tautology because the population exchange was done on the basis of religion, not language. There were plenty of Greek speaking muslims and Turkish speaking orthod…
