That sure is one compact document. Pun intended. The document is very readable too.

Very likely no. Airline routes between touchpoints usually follow great circles, not constant bearing paths. Great circles are shortest paths and also they do not need any steering (modulo crosswinds …

True but it's really nice way to get the benefit of type checking in Python. Just like you, I had started using Cython for performance but then realized that I can discard a bulk of type errors i…

That's true for current ML offerings. However, I think an ML designed for machine learning would be nice, especially if the type system is extended to multidimensional arrays shapes. Pattern matc…

You could try Cython and Lush. An ML dialect for ML would have been nice, but doesn't exist.

> Arguably, every classroom (and home with children) should have a globe Or even better is to build one. It is a lot of fun. It is very instructive to understand why you need to shape the gores tha…

The problem that Mercator was trying to solve and the solution he came up with is super interesting to me. Very neat. It is still not known for sure how he came up with mathematical details of the str…

All the best for your endeavour. It's a big one you are tackling.

So you haven't heard from there lawyers yet ? Hope it stays that way. Does Woxi also show intermediate steps ? That to me is a killer feature of Mathematica.

Ah! I see. Thanks for the reference.

For spherical geometry you should not need to do anything special, no ? Compute the Voronoi tessellation as usual and then project the linear separators back to the sphere (by connecting points on it …

The first thing I noticed was the spherical Dodadecahedron and if you turn on Delaunay triangulation button, then it's dual the Icosahedron, my favourite, the relationship is entirely platonic.…

Curious about why you think he is using Euclidean. From the looks of it the separators seem to be segments of great circles. That is what you would get as loci of angular bisectors. Angular bisectors …

Struck by (his) Poes I suppose.

I have no context. Was that sarcasm ? I have no idea if this is expected or unexpected of Raymond.

Not specifically those either. This is about inner product functions in a specific kind of Hilbert spaces, a notion that is very useful in many branches of applied mathematics. Machine learning and fu…

'Shocking', 'striking', 'disappointing', 'will shock you' -- the article is padded with hyperbole.

Indeed. It is probably the most significant thing that ever happens to a person. My sincere condolences. I have not dealt with such a change but have dealt with grief. Try to catch the sun rise. It is…

Definitely an applied maths paper given that it has been published under CS/ML and been accepted at ICML.

Probably happens to other social animals too.

Much bigger than non-derivative stock market for sure. "The derivatives market is, in a word, gigantic—often estimated at over $1 quadrillion". The stock market would be puny in comparison. …

Not just HFT, options market, futures market are all zero sum. They are massive.

Thanks for the correction. I saw the books in the book stores several months after the movie release. I suppose they were doing a rerun to toe in with the movie's popularity.

I think the movie came first, at least in the US.

> my lived experience tells me the Earth is flat. That ship has sailed, beyond the horizon. Hope you catch the reference.

But then according to the tenets of efficiency of a free market system no candidate would be spending so much on advertisement. You can't have it both ways, (i) free market is ideal and efficient…

Same here but was curious about stats of broken heart syndrome anyhow.

Thanks.
