An interesting abstract

By Zirui Wang.

The paper is D. J. Platt and T. S. Trudgian’s Zeroes of partial sums of the zeta-function, whose abstract reads:

This article considers the positive integers $N$ for which $\zeta_N(s)=\sum_{n=1}^Nn^{-s}$ has zeroes in the half-plane $\Re(s)>1$. Building on earlier results, we show that there are no zeroes for $1\le N\le18$ and for $N=20,21,28$. For all other $N$ there are infinitely many such zeroes.

I found the Buddhist position defendable!

By Zirui Wang.

Well, it seems absurd, but as you try to adopt the position, it’s very easy to defend. Basically, as they say, all for one and one for all. Or everything is nothing and nothing is everything. Therefore nothing is important; nothing should be attached to; and one should let go of all. And there is nothing to begin with, so nothing to let go of at all! Then you enter this supreme calmness. There is nothing and everything and all these coming-and-go images. You are alone. You come alone and go alone. It’s like traveling. I don’t know if it’s correct. But you are not hurt. The world is separate from you. You do make contacts but that’s also coming-and-go. That’s the feeling. The strategy of escaping is the best strategy; that’s what I know.
