The most impressive optimization in this work is the number of click-bait words crammed into a single title. A number of alarm bells are set off with a cursory reading of the article: 1. The algorithm was run on a model of the Higgs, no

Upperclassmen scared the bajeezus out of me when I got "Killer" Cain for calculus 3 my freshman year. The stories couldn't have been further from the truth - he was certainly tough, but also a fair, rigorous, and thorough te

If you can demonstrate standing and pay a lawyer a ton of money, then yes, you could argue that.

Ah, but it is a filter - it filters out high frequency noise. One interpretation of the Kalman filter is a variable cutoff low-pass filter. The cutoff is determined by the Kalman gain. Note the similarity between the Kalman state update

Not quite. All AWD Subarus (i.e. except the BRZ) have one output shaft out of the engine, 3 out of the transmission/transaxle (2 to the front tires, 1 to the rear diff), and 2 out of the rear diff. Torque split varies between models

I'd agree that the alpha-beta filter is a special case of the Kalman filter (which isn't what I'd call a subset, but maybe we're just arguing semantics). All the filters you mention are certainly related, but claiming t

One of the defining characteristics of the Kalman filter is that it computes a gain (called the Kalman gain) that is a function of the state covariance and the measurement covariance. Alpha-beta filters use constants, so I'd say no, t

If you're really trying to find a cooler name than the obvious low-pass IIR filter, you could call it an "alpha filter", which is equivalent to a position only (no derivatives) Kalman filter in steady-state, using a precomput

>> I had no clue planets could have an elliptical shape. They can't, as one of the defining characteristics of a planet is having enough mass to be rounded under it's own gravity. Dwarf planets have no such restriction.

Does anyone believe that the difference between the Lebesgue and Riemann integrals can have physical significance, and that whether, say, an airplane would or would not fly could depend on this difference? If such were claimed, I should not

High intersection angle CV joints. Similar in purpose to the joints between the driven wheels and power plant (transmission/transaxle/rear diff/whatever) in your car, but Persian joints can tolerate much steeper angles.

"all analogies are false and therefore bad" I disagree with this statement. If you try to learn everything from first principles, you'll never get anywhere. Students need analogies to understand the big picture while learni

Any time someone appeals to quantum physics to offer a handwaving explanation of something that classical physics covers just fine, watch out. Using path integrals to introduce interferometry is a waste of time, and in this case, just plai

I discourage anyone wanting to understand the physics of beamforming antennae from reading this article. The author has a very poor grasp of the concepts.

The efficiency gained by stepping up AC to higher voltage (and correspondingly lower current) is far greater than that lost to skin effect. Since there is no way to efficiently step up DC (modern DC-DC converters are still horribly lossy),

You keep using that term MAD. I do not think it means what you think it means. You seem to imply that it's simply a policy of retaliating against any first strike with massive and lethal force. In fact, MAD, as a theory of nuclear de

Adjusting the measurement covariance to fit the residuals is not part of the Kalman filter algorithm. One could make the argument that any real-world implementation needs to address this problem, but as far as the algorithm is concerned, t
