Ein mathematischer Gottesbeweis
Ein mathematischer Gottesbeweis geht zurück auf Guido Grandi und wurde vor kurzem wieder mal ausgegraben von u/Prunestand bzw Cliff Pickover.
0 = 0 + 0 + 0 + ... = (1-1) + (1-1) + (1-1) + ... = 1 - 1 + 1 - 1 + 1 - 1 + ... = 1 + (-1 + 1) + (-1 + 1) + (-1 + 1) + ... = 1 + 0 + 0 + 0 + ... = 1
was letztendlich einer Schöpfung aus dem Nichts entspricht wo doch eigentlich “nihilo ex nihilum” gilt.
Die Grandi-Reihe hat nur leider keinen Summenwert, weil sie nicht konvergent ist. Anders gesagt
0 + 0 + 0 + ... # N Elemente (1-1) + (1-1) + (1-1) + ... # 2N Elemente 1 - 1 + 1 - 1 + 1 - 1 + ... # 2N Elemente 1 + (-1 + 1) + (-1 + 1) + (-1 + 1) + ... # 2N + 1 Elemente 1 + 0 + 0 + 0 + ... # N + 1 Elemente
dh die 4. Zeile enthält eine falsche Aussage.
Frustriert oder erleichtert? Auf arXiv geht es weiter mit Gödels Gottesbeweis.

increasing complication
Another famous article from the past: P. W. Anderson “More is different” 50 years ago
… the next stage could be hierarchy or specialization of function, or both. At some point we have to stop talking about decreasing symmetry and start calling it increasing complication. Thus, with increasing complication at each stage, we go up on the hierarchy of the sciences. We expect to encounter fascinating and, I believe, very fundamental questions at each stage in fitting together less complicated pieces into a more complicated system and understanding the basically new types of behavior which can result.

Glad to help
Raspberry Pis are small single-board computers. As I have two of these devices already up and logging solar power production on my roof they could do even more: They are not only supporting a green environment but can also help people from countries with repressive governments by installation of another software package.
Snowflake is a system to defeat internet censorship. People who are censored can use Snowflake to access the internet. Their connection goes through Snowflake proxies, which are run by volunteers.
Setup takes only 2 minutes – full instructions are at kuketz-blog.de
# sudo apt-get install git # sudo apt-get install golang git clone https://git.torproject.org/pluggable-transports/snowflake.git cd snowflake/proxy go build nohup /home/pi/snowflake/proxy/proxy > /home/pi/www/snowflake.log 2>&1 &;

More humility needed
Hoekstra and Vazire on “Aspiring to greater intellectual humility in science”
Although intellectual humility is presented as a widely accepted scientific norm, we argue that current research practice does not incentivize intellectual humility. We provide a set of recommendations on how to increase intellectual humility in research articles
Indeed – many recommendations are counterproductive for a science career…
and well, a divergent view at PubPeer.

The currency of the New Economy won’t be money, but attention
Time to revisit the groundbreaking 1997 @mgoldh paper in Wired “Attention Shoppers! The currency of the New Economy won’t be money, but attention”
As is now obvious, the economies of the industrialized nations – and especially that of the US – have shifted dramatically. We’ve turned a corner toward an economy where an increasing number of workers are no longer involved directly in the production, transportation, and distribution of material goods, but instead earn their living managing or dealing with information in some form. Most call this an “information economy.”

Disagree without being disagreeable?
The NIH director on communication with the NIH
We are committed to ensuring a safe and respectful workplace wherever NIH-supported research occurs. Be it at a recipient institution, at a conference where scientific ideas are exchanged, or in our own intramural labs, everybody deserves to work in an environment that is free of harassment, bullying, intimidation, threats, or other disruptive and inappropriate behaviors. Likewise, this goes for NIH program officers, scientific review officers (SROs), grants management specialists, and other extramural staff.

Civil disobedience by scientists
Time is short to secure a liveable and sustainable future; yet, inaction from governments, industry and civil society is setting the course for 3.2 °C of warming, with all the cascading and catastrophic consequences that this implies. In this context, when does civil disobedience by scientists become justified?
Not all scientists believe in never ending progress.

Endlich neue CV Formulare bei der DFG
Quelle DFG 1.9.22 https://www.dfg.de/en/research_funding
Publication details in proposals and CVs
Performance assessment based on content-related qualitative criteria also explicitly includes ensuring that the entire spectrum of academic publication types are equally displayed and acknowledged in funding proposals and CVs. In addition to a maximum of ten publications in the more common publication formats, the CV can therefore now list up to ten further sets of research outcomes and findings that have been publicised in a variety of other ways, including articles on preprint servers, data sets or software packages, for example. In DFG proposals, the project-specific list of publications will be included in the general bibliography. The intention here is to shift the focus of the review and the evaluation of a proposal away from the list of publications and towards the substance of the applicant’s accomplishments. In order to document their own published preliminary work, applicants can typographically highlight (e.g. in bold) a maximum of ten of their own publications in the bibliography that are important for the project. No information on quantitative metrics such as impact factors and h-indices is required in the CV or the proposal, and such information is not to be considered in the review. The relevant details are included in DFG forms and review instructions.

WordPress displaying Jupyter notebook
I could not find any plugin but a step-by-step guide at a blog commentary
1. Download your notebook as .ipynb file
2. Upload to https://jsvine.github.io/nbpreview/
3. Open your browser dev tools and copy the element id=”notebook-holder” from the DOM
4. Paste it in your WordPress post as raw text
5. Grab CSS from https://jsvine.github.io/nbpreview/css/vendor/notebook.css
Maybe a true notebook in an iframe is a better solution?

Please do not try to tell a story but report your results
When I prepared a lecture last year on scientific paper writing I have found countless advices how to tell a story – it made it even into elife.
Don’t do that – there are lies and damned lies (Disraeli) while you are easily running into a trap when trying to “tell a story”. Preregister your study plan, tell the world what you did right from the beginning, what did not work, why you repeated an experiment or why changed your opinion.
Writing a story from the backend distorts the proportions and misdirects attention. Ulrich Dirnagl highlighted this problem in an earlier talk here in March using the following two slides.
