It indeed was a fantastic place, doors nailed to the walls, trying out the newly fledged Mapreduce and Charlie's. Good times. Good times.

They are a fun way to demonstrate LCM and GCD too https://en.wikipedia.org/wiki/Arithmetic_billiards With curved reflecting boundaries and parallel rays you get the beauty of catacaustics. A familiar site in a cup of c

No sarcasm intended, I was being literal. Me and my wife have different mother tongues. What's natural to her isn't to me and vice versa and we keep telling each other that it's easy.

Oh it seems you took it personally, whereas I mentioned "every native speaker". My intention was not to rule you, just to underscore the point that native speakers have it easier and may not be able to experience or understand the

If you ever feel inclined to learn Hindi there is more to grapple with. The verb gender is sometimes set by the gender of the object, sometimes by the gender of the object. Which way this will go loosely depends on tense.

Understanding how complex generating functions help with combinatoric counting makes one's head spin. (Tenuous pun intended. It keep track of how spinning arrowheads align with or cancel each other)

Imagine a civilization that discovers complex numbers before naturals, with naturals showing up to count the turns. If hexagons can claim to be bestagons complex numbers have a legit claim at best numbers.

Maybe so, but for the good shots by the thinking guy, I suspect he would derive longer term emotional gratification from how well they came out. Effort and investment adds to the experience. Making things easy is good as long as it is not t

Is it worthwhile para-droping or glide-dropping excess fuel within airport open grounds reserved for that purpose. I understand that floating into the main theatre will be a serious problem. Current weather should allow making those calls.

Ah! I was talking about the abstraction of point masses, then there is the shell theorem. But now at least I understand the discrepancy. In any case gravitational potential at infinity is formally defined as 0 in Newtonian physics.

by srean 10d ago
But what's the integral of 1/r^2 from 0 to \infty ...that's the part not that not squaring up. Newtonian gravitational potential of a point mass at origin of mass M is - GM/r so at r = \infty the potential is zero. Well,

I think he wanted to get the cuteness of the Archimedean result off his chest. Very understandable emotion.

Yeah, I had read one of your parallel comments and understood what you had meant. Differential privacy is a good formulation (well, the only one I know) to deal with the peeking problem in general.

I should have said that it rises to zero, assuming standard sign conventions. The gravitational potential infinity of a point mass at the origin is defined to be zero. Could you expand on why you think it approaches a constant, presumably a

In a 3d world one can escape from the Earth's gravitational field. On the flat-world equivalent there is no escape. You can checkout but never leave. There ought to be a science fiction story based on this premise. Things get interes

You raise a good point. I had not considered the pedagogical value of starting with PAC Bayesian bounds. It will be interesting to see ML courses that take that route. Similar issues show up in traditional statics when considering multi-hyp

What threw me off was the (possibly misunderstood) suggestion for minimizing the generalization bound over the prior after the data has been incorporated.

" Can be misleading" is an accurate characterization. It is an uniform bound and will have problems with very large hypothesis classes but its statement isnt wrong (just that the tool is a little heavy handed). For simpler models

> Then reduce the variance on a Gaussian prior. Are you sure that doing this after seeing the data is valid and does not suffer from the equivalent of peeking-into-the-test-set problem ? There are ways to address the peeking problem but
