It just piles up

This is the third in line of three posts about “worldly” problems, with the diplomacy one here and the diversity one here. I will probably also write one on freedom of expression at another point, which is a different topic important to me, but you know, this entire site is an exercise in speaking my mind on whatever I want. Needless to say, this is different from mathematics in that the problems are often trivially solved, but the implementation often comes with resistance. I mean, outside of alphabet agencies, a mathematical theorem rarely endangers your life. Well commutative algebra does. And you know, having both in your life is kind of nice 😉

In a small update to this post, I remember visiting a spring next to Jerusalem, in Lifta, with a dear friend. It is small and beautiful, and close to one of my favorite works of architecture, that impressively greets you once you enter my favorite place in the world.

But of Lifta, I mostly remember one thing: The ungodly amounts of trash that were littered in and around the spring. There is a clear issue in that once it reaches a level of visibility, people tend to loose all morals and just add to it.

Not because it is easy…

and not because it is hard either.

A few years ago there was a heated discussion about diversity statements, initiated by an opinion by my friend Abby. And I felt that either way, either side missed a critical point. A quick overview: Diversity statements are a requirement that some universities, some science foundations and some companies require. Abby argued against them, some people argued for her, some against. All in all, it was kind of ugly.

And what is really the issue, the real culprit, the thief in the night, could just get away.

Because you see, universities, governments, companies etc. can say that they required a diversity statement, and they are done. That they imposed a quota for the organization or attendance of a conference, and they did their duty. Alas, the hard part, to actually enable participation, is usually not given. It is not easy for a parent to juggle childcare and studies, it is not easy for a disadvantaged person to attend a conference or workshop or university in the first place.

Sustainability, climate change and intersection cohomology

While I ponder one of my great loves, intersection cohomology, and a cat meows in protest because I can only really think while pacing around, which prevents cuddling (apologies also to the neighbors living below me), I want to discuss, for a second, the issue of sustainability.

Oh my perverse sheaves, why have you forsaken me?

There are immediate things we can and have to do to preserve the planet, such as more sensible and sustainable encounters with our waste, our energy, or transport, with respect to what we eat and what and how much we buy. Most of what we buy and produce is not actually needed, and that includes the hyperloop (which is an interesting engineering project at best).

But these notions are obvious (well, they should be). Then why is it still getting pushback, why are changes slow?

Keynesian dialectics, the Ukraine-Russia war, and the problem with amplitudes

What is a public documentation of half-knowledge if not something one can cringe about when looking back in a few years.

Motivated by a very real rule that made it tricky for me to invite a collaborator.

Let me start with a triviality. The amount and value of information any member of society possesses at any given point in time, is subject to fluctuation. Just like the amount of economic capital we have at our disposal is undergoing ebb and flow, so is the informational content we can lord over.

Corollary is that the flow of information, and its volume, is an ebb and flow.

All high brow nonsense, but let me apply this to the current situation. No particular perspective taken.

The first order of approximation is that we think the other side is doing bad, and hates us.

This applies to every side, however. The west hopes for a coup (which will be bad, at least in short term, for the Russian populace) or a humiliating defeat (which will be equally bad for the Russian populace). The Russian side hopes for a victory, an expansion of territory, and a reemergence of Russian might (which needless to say will be bad for Ukraine). Currently the signs point, mildly speaking, to a defeat of Russia.

And rightly so. Ukraine is fighting for its self-determination, nothing less.

The effect will be a further fracturing of the world. This applies not only to the present conflict, which serves merely as example, but equally to Israel (I remember vividly the first time I arrived to the country, and hearing from encounters of both groups that one could not talk to the other side because “they want to kill us”), the emerging conflict with China or many other examples.

That is not to say that more open people do not exist, in all walks of society (and I count my best friends among them). However, this may become an increasingly fringe viewpoint as not only the respective groups stay in their respective echochambers, but these partitions of the world become increasingly enforced with real and permanent restrictions (see the restriction of social media in some countries).

I feel that I woke up to a post-Covid world that will, for some time, not be open again. That walls were increased in height. And now, behind those walls, pressure will increase further until both sides will suffer an explosion. Or many.

The second order of approximation is that we realize the other side thinks we are doing bad, and that we hate them.

Hence the logical thing is to work anticyclically. In peacetime, one of the tasks of politics is to keep the peace. Now that politics is pointing towards a war of systems, we have to soften the blow. Decrease the pressure. And while my personal modus operandi is to circumvent rules I think are nonsense, there are much easier things that can be done.

This involves keeping lines of communication open.

It involves keep if only to fight with your friends and enemies rather than avoiding uncomfortable discussions.

And while boycotts can be measures that I support on occasion, I like to avoid boycotts of information. Because intel is the one thing that can decrease pressure.

(Unless you are boycotting me, of course. Continue at your own leisure. I have at best been described as weaponized incompetence).

Concretely, I think we have to keep communication to Russians open. Because many are trapped in an echo chamber (as everyone is. I learned only recently I should not use the idiom “jedem das seine” (german for to each his own, with a dark connotation) 😉 ). Because at the very least, while they may not be an empire anymore, a free discourse is welcome. So don’t only communicate to those whose mind is already open, but equally to those whose mind is not.

The current approach I would favor is to speak softly and carry a big stick. We are carrying a big stick, and Russia/Putin knows (the Ukrainians are pushing back the Russian Empire with sticks we made mostly 20-30 years ago, and their own which are even older). We are making that stick even stick even bigger and are putting quite a few thorns on it (which I am afraid will not only be necessary vis-a-vis Russia). That is necessary and good. However, many of them are caught in an information bubble that will invariably collapse, and the cost of the Russian populace will be dire.

Moreover, there is a strategic aspect. A Russia that collapses and is humiliated, but does not reform (either because Putin is still around, or because his successor is just as deluded) and that hence will be ostracized and excluded from Europe will inevitably fall into another domain of influence, most likely ending up a vassal state of some other power.

But to reform Russia, the reformers need support. And this likely cannot come out of the ranks who already support reform. Diplomatically, we have to extend an arm to those that are still caught in the bubble, but only stay there because there is no alternative. I think there is no convincing some of them, but one has to try with those in the middle from time to time.

There are many obstacles. And, if not taken so serious, there are many ways around them.

Fun fact: there was a lot of fun being made about Russia calling it a special military operation, rather than a war. Did you know that the last war congress declared was in 1942 against Romania?

Kabelsalat, Schoolification, science education, flattening PL maps and Ronly Honly Bing

First bullet point: There is an interesting analysis of the secret deals that led to the war in Ukraine at the moment by the New York Times, as well as an account of the Trump administration involvement.

This post is brought to you by the letter A for anger issues, and the failed attempt to find an HDMI cable. Why is it that usually there are enough of them to choke two species into extinction, rid Paris of her rat-issues and still have enough for the Praelatura Sanctae Crucis et Operis Dei to flagellate themselves biweekly, but now I cannot find a single one.

Second: Something is rotten in the state of Denmark. Ok, I am being overdramatic; though if I was talking about the level of paranoia this country sometimes presents when faced with youth whose skin is not piggy-pink, that could well be appropriate.

I am also not referring to royal family affairs and the queen’s dental care.

Also, the issue is not really restricted to Denmark. I just really wanted to quote Marcellus.

What I am referring to is an increasing effort to make university a school. And as someone who hated school, let me say:

Corruption, Lobbyism and postdoc/student positions

A while ago, I learned about a case quite curious. Someone offended a foolish little devil, or a devil playing the fool; something small, irrelevant and mosquitolike, the offender a nyaff and nudnik, a gunnif, really. The offender a public person, as it turned out. A politician, if mind serves me well. The story continued to give background to what had been read in newspapers so often; how, determined, files were obtained to prove corruption and bribery. The files were forwarded to authorities, arrests were made. End story.

Reading this, I am not in principle opposed to those acts; to gain favor can be considered parts of human nature. Confusion just arises as to the what and how. And here I intend to be a little helpful. Now, while I am not currently looking for submarines or have critical infrastructure to sell to foreign dignitaries, there have nevertheless been attempts to bribe me for the little I have to offer. For the readers perusal, I will rate some of the bribery attempts that came in material form; though in reality, I am mostly a sucker for what your mind has to offer.

And currently, I am hiring. My research interests you find in the other posts of this blog and my website, but to be honest, I am almost looking to hear something cool. So hit me up and let’s chat.

If you cannot offer ideas, the following might help (heavy sarcasm, because this is the internet). No particular order.

A (mostly) live lizard

A most transparent attempt to gain my favor by my esteemed coauthor. Nevertheless effective. RIP little fucker. I give it a perfect 5/7 lizard tails.
