comment Fourier Series: Integral of a Sum or Sum of Integrals?
This does not seem to answer the question.

Also, your drawings are pretty damn good if you don't have a stylus... Also with.

As for the "taking with you". You can put the files in a dropbox folder and the iPad client synchronizes them when you need.

comment Completeness of BMO without duality to $H^1$
That's what I say. In the quotient space. Maybe a bit "strange", but all the constants are now in the class $[0]$. Whatever, just get rid of the average and work with those functions.

comment Completeness of BMO without duality to $H^1$
@AlexanderAmenta I'm not sure what the problem is. As I am a bit ill al the moment, I still have tried to add some information :-). The idea is that it can only be a Banach space if we have a full norm. That means we should divide out that constants. In practice this means that taking the quotient gives us the normal BMO-norm for non-constants and the constant itself for constants. So, you are fine by just considering functions with average 0. Then no worrying about equivalence classes.

In these things seminorms suck. Consider equivalence classes of functions that are the same up to an additive constant.

@AlexanderAmenta But you get it for every compact set, I don't understand the question.

comment Example of application of the Uniform Boundedness Principle
Nice proof, but indeed: it can be done easier. However, you can also use BS to prove there exists a function such that the Fourier series diverges.

comment Advantage of accepting non-measurable sets
@MichaelGreinecker The second part about probability theory seems to suggest to me that we are doing it wrong if we need to consider all the other events which are not even there. Do you know free probability? That takes the random variables as primitives.

comment A question about a proof of a weak form of Hilbert's Nullstellensatz
Thanks for the link. I always wanted to learn more about commutative algebra and your writing style suits me very well (as in that you don't make it sound more fancy than it actually is for example).

comment Drying blood - an algorithm for calculating the geometry of blood stains
@Rahul Maybe for pure mathematics, but it can surely be a good question for applied (and computational) mathematics where things are not so clearly defined. Maybe this is not the right forum?
