> "emigrated to the United States in 1943" It's always sad hearing about great minds who fled Europe shortly before or during World War II. It's a reminder of all the great minds whom we lost in the last war, and of how destructive war is to technological and human progress.

I read a few articles on that website specified by the post and I was very happy not to be a contemporary Hungarian, both from a current problem, and political philosophy point of view.

Earlier quoted context omitted.

Something that Toyota apparently doesn't do; their fuel gauges take over a minute to react fully when you turn on the car after filling the tank.

How about a mechanical low-pass filter?: A vertical tube connected to the tank via a tiny hole would not be affected much by sloshing, but would slowly drift towards having the same level of fuel as the tank has on average.

That's pretty much what fuel tanks do.

The Kalman Filter was used the in the Apollo 11 Guidance Computer [0] (discussed in the past on HN [1]). As someone linked previously, here is a historical perspective [2], and a link to the actual state vector update computations [3]. The AGC maintained the state vectors for the KF. Ground control would run batch mode least squares solutions, and pass it on to the LM, where the updates to the state vector would be a…

FYI: I was reading the README to understand what Kalman Filters are. This section seems to end abruptly mid-sentence at "You might imagine" without explaining what Kalman filters are: https://github.com/rlabbe/Kalman-and-Bayesian-Filters-in-Pyt...
