Robert J Lifton wrote in “Losing reality”

Trump is different. His solipsism is sui generis. He is psychologically remarkable in his capacity to manufacture and continuously assert falsehood in the apparent absence of psychosis.

Not unexpected the advice was rejected by basically all medical professionals. Commentaries are raging in Nature, BMJThe Lancet, JAMA and even the WHO. Continue reading Paracetamol and autism in “Environmental Health”: A dubious paper that made politics

We did not learn the COVID19 lesson

me 2020

The epidemic started with a few cases during the winter holidays, increased exponentially afterwards including significant more cases by beer festivals and another significant excess of cases following the election that occurred in Bavaria only. Compared to other German countries, Bavaria reached the highest prevalence which could not be reversed by even the most restrictive containment measurements. To be effective, NPIs need to applied early, if possible even before the beginning of the exponential phase.

Jeremy Farrar 2022

When you look back, what was the most momentous mistake in the pandemic response?
Farrar: The biggest mistake was that we didn’t take it seriously enough in the first six weeks of 2020. It was the time when a pandemic could still have been prevented. From the beginning of January, it was clear what was happening in Wuhan. By the end of January, it was clear how dangerous the situation was. And even though this information was  available, the rest of the world didn’t act until March – two critical months passed in which the virus was spreading. Instead, we had a U.S. President Donald Trump, who dismissed what was happening as “kung flu,” and in Europe, at least in the UK, there was a sense that this was all happening in faraway China, and northern Italy was also somehow different – it won’t be so bad here. It was a kind of complacency, the arrogance of exceptionalism.

“Ecce Homo” by Caravaggio

An interesting documentary at Isabella/München

It has some unexpected turns while at the end basically everybody seems to be happy — although we neither know the buyer, the price and  the courtage. And just 9 months display at Prado is a bit disapppointing, isn’t it?

Doubts remain also about the authorship as the work is not signed by Caravaggio as nearly all of his paintings. There was  a large number of “follower” as many artists were influenced by Caravaggio’s style and techniques. And well, there is an exceptional high value included where all people involved have a significant financial incentive: seller, auction house, trader, experts, museums …

I am not very much impressed by the hands and also the documentation raises questions

Most of the scholars who have examined the painting date its execution between 1606 and 1607, either during the artist’s last months in Rome or after his escape to Naples after impaling the local gang boss Ranuccio Tommasoni with his rapier during a game of tennis.

So did Caravaggio leave an unfinished painting? Did another painter complete it?

Camillo Manzitti, writing in Finestre sull’Arte (May 2024), contends that after restoration, the painting reveals a moderate chiaroscuro and lack of the dramatic tension characteristic of Caravaggio. He specifically highlights weakened emotional expression. Pilate appears only vaguely sad, not deeply troubled, and the young man behind Christ lacks the hallucinatory horror typical of Caravaggio’s depictions. The poor anatomical modeling, which he argues is incompatible with Caravaggio’s known skill. Christ’s face is asymmetrically deformed, with misaligned eyes and an ear inserted at an unnatural angle. Pilate’s face also shows modeling weaknesses. Kolja Thurner, an art historian based in Berlin, voiced his doubts via X as “a good painting by a talented Caravaggio follower, stylistically imitating the master to a high degree.”

BTW – the Guardian has the best reproductions IMHO.

COVID19 und Politik

Ich habe den Plot  hier schon 2020 gebracht, wie im Osten Deutschlands die Inzidenz vor allem von Landkreisen mit primär AfD, FDP und CDU Wählern nach oben getrieben wurde.

https://www.wjst.de/blog/sciencesurf/2020/12/eine-politische-frage/

Zum Teil stand das auch in unserem Artikel von2021 wobei ich jetzt über den Citation Alert auf eine weitere interessante Arbeit von Zehring und Domahidi  aufmerksam wurde “The language similarity between corona protest  mobilizers on Telegram and German politicians on Twitter“. Sie zeigen

Protestbewegungen gegen Maßnahmen zur Eindämmung der COVID-19-Pandemie, wie beispielsweise die deutsche Bewegung Querdenken, verfolgen das Ziel, ihre Positionen auf die politische Agenda zu setzen. Während die rechtsgerichtete Partei Alternative für Deutschland (AfD) im Deutschen Bundestag als parlamentarischer Arm von Querdenken agierte, bleibt die Rolle anderer Parteien bislang unzureichend erforscht. … Grundlage [der Studie] bilden n = 934.432 Telegram-Nachrichten von Querdenken sowie n = 445.690 Tweets der sechs im Bundestag vertretenen Parteien in den Jahren 2020–2021. Methodisch kamen eine Kombination aus Sentence-Transformer-Modellen, Zeitreihenanalysen sowie einer ergänzenden manuellen Bewertung zum Einsatz. Die Ergebnisse zeigen, dass sich nach Herbst/Winter 2020 sämtliche untersuchten Parteien – wenn auch aus unterschiedlichen Gründen – semantisch zunehmend an die Diskurse von Querdenken angenähert haben. Während die Kommunikationsmuster der AfD die größte inhaltliche Nähe aufweisen, lassen sich auch bei Teilen der Freien Demokratischen Partei (FDP) sowie der Christlich Demokratischen Union/Christlich-Sozialen Union (CDU/CSU) Übereinstimmungen feststellen, etwa hinsichtlich der Abwertung linker und grüner Politik sowie der Ablehnung pandemiebedingter Eindämmungsmaßnahmen….

Aus den Schlagzeilen verschwunden, aber noch längst nicht erledigt

„Freiheit ist die Freiheit zu sagen, dass zwei plus zwei vier ist.”
George Orwell, 1984.

Hier das Manifest Pro Realität

Wir verstehen uns als liberale, progressive, weltoffene, linke und feministische Stimmen, die für Pluralität und Toleranz einstehen. Alle Menschen müssen leben dürfen “nach dem Gesetz, nach dem sie angetreten”. Gerade deswegen aber sehen wir mit Sorge, wie fatal die Debatte um Sex und Gender derzeit läuft. Bestürzt müssen wir zur Kenntnis nehmen, dass falsche und zum Teil regelrecht aberwitzige Verdrehungen (“weiblicher Penis”, “die Biologie ist längst weiter”, “es gibt mehr als zwei Geschlechter”) gerade denen in die Hände spielen, die unsere demokratische Vielfalt mit dumpfen Parolen bedrohen…
Der funktionale Begriff “Geschlecht” ist in der naturwissenschaftlichen Community unstrittig: Biologisch gibt es bei allen Arten, die sich über das Verschmelzen ungleich großer Keimzellen vermehren (Anisogamie), nur zwei Arten von Keimzellen – und daraus abgeleitet zwei Geschlechter, die als männlich und weiblich bezeichnet werden…
Auf dieser biologischen Grundlage der Zweigeschlechtlichkeit gibt es kulturelle und soziale Erwartungen und Geschlechterrollen. Es ist ein Kennzeichen liberaler Gesellschaften und eine große Errungenschaft der Emanzipationsbewegung des neunzehnten und zwanzigsten Jahrhunderts, dass Geschlechterrollen keinen zwingenden Charakter mehr haben und dem Individuum alle gesellschaftlichen Rollen unabhängig vom Geschlecht offen stehen.

The decline of science is now official

Coming from an official announcement

https://www.whitehouse.gov/presidential-actions/2025/08/improving-oversight-of-federal-grantmaking/

Every tax dollar the Government spends should improve American lives or advance American interests.  This often does not happen.  Federal grants have funded drag shows in Ecuador, trained doctoral candidates in critical race theory, and developed transgender-sexual-education programs.  In 2024, one study claimed that more than one-quarter of new National Science Foundation (NSF) grants went to diversity, equity, and inclusion and other far-left initiatives.  These NSF grants included those to educators that promoted Marxism, class warfare propaganda, and other anti-American ideologies in the classroom, masked as rigorous and thoughtful investigation.

While I once believed that funding should primarily support the advancement of core scientific methods and studies rather than numerous DEI initiatives, this view is a grotesque distortion of reality, especially when we consider the so-called “study” the White House is citing. Many DEI projects are, in fact, valuable educational efforts or have an environmental focus, often addressing critical research needs that receive little to no funding from other sources.

Here is  a brief overview how these numbers were produced, and key problems that I have with the methods. The statement comes from the October 9, 2024 Senate Republican staff report Division. Extremism. Ideology: How the Biden-Harris NSF Politicized Science from the U.S. Senate Committee on Commerce, Science & Transportation, then led by Sen. Ted Cruz (PDF, the original is no more available on Aug 12, 2025).  The underlying dataset was released on February 11, 2025 (press release and database).

https://www.commerce.senate.gov/services/files/FA4D5565-5056-4916-AF87-64C96EAB8FEA

Staff analyzed 32,198 NSF prime awards with start dates between January 2021 and April 4, 2024. Using a keyword-based tagging process, they identified 3,483 awards they labeled as “DEI/neo-Marxist,” totaling more than $2.05 billion. The report says that for 2024 (measured only up to April 4), 27% of new grants fell into this category. Appendix A of the report explains the method. Staff pulled all NSF awards from USAspending.gov with start dates in the 2021–2024 window. They ran an n-gram/keyword search using glossaries from sources like NACo and the University of Washington, expanding the list to more than 800,000 variants. Awards with zero or only one keyword match were removed, and additional filtering plus manual checks produced the final set of 3,483. Grants were grouped into five thematic categories (Status, Social Justice, Gender, Race, Environment). The “27% in 2024” figure came from the share of awards in that subset with start dates in the first quarter of 2024.

Faults and shortcomings in the method

  • The keyword approach equates the presence of certain words with being a DEI-focused grant, and the keyword list is very broad (including terms like “equity,” “privilege,” “climate change,” “systemic,” “historic*,” and “intersectional”), which can capture unrelated research.
  • The 27% figure comes from only part of the year (January–April 2024), not a full year.
  • There is ambiguity between counts and dollar amounts; the 27% refers to counts, not necessarily to total funding share.
  • Removing all single-keyword matches and applying manual pruning introduces subjectivity and potential bias.
  • Categories like “Social Justice” or “Race” are based purely on word presence, not actual research aims, conflating standard NSF education/broader impacts work with political advocacy.
  • Reliance on abstracts and spending descriptions means the screen often catches standard boilerplate language that NSF requires by law.
  • A House Science Committee Democratic staff review in April 2025 found numerous false positives in the Cruz dataset, such as biodiversity studies flagged for the word “diversity” or wildlife grants flagged for the word “female.” That review also notes that NSF is required by statute to consider “broader impacts” in all awards.
  • The Senate report is a partisan staff product, not peer-reviewed, and uses normative framing (“neo-Marxist,” “extremist”) rather than neutral description.

Sagan Standard

This is not about the extraordinary cyclist Peter Sagan but about the astronomer Carl Sagan who postulated  in his 1979 book  “Broca’s brain” that “extraordinary claims require extraordinary evidence”

A major part of the book is devoted to debunking “paradoxers” who either live at the edge of science or are outright charlatans.

A forensic analysis of the Prince Andrew/Giuffre/Maxwell image

There are only a few photographs that made headlines recently. One is Man Ray’s Le Violon d’Ingres for its price tag of $12,400,000.  Or the authorship discussion around the  “Napalm Girl” Phan Thị Kim Phúc.  And there is a third photograph – a snapshot from a London house two decades ago – that has a similar price tag attached like Le Violon d’Ingres.

 

My most recent paper at https://arxiv.org/abs/2507.1223 examines this infamous photograph using the latest image analysis techniques.

This study offers a forensic assessment of a widely circulated photograph featuring Prince Andrew, Virginia Giuffre, and Ghislaine Maxwell – an image that has played a pivotal role in public discourse and legal narratives. Through analysis of multiple published versions, several inconsistencies are identified, including irregularities in lighting, posture, and physical interaction, which are more consistent with digital compositing than with an unaltered snapshot. While the absence of the original negative and a verifiable audit trail precludes definitive conclusions, the technical and contextual anomalies suggest that the image may have been deliberately constructed. Nevertheless, without additional evidence, the photograph remains an unresolved but symbolically charged fragment within a complex story of abuse, memory, and contested truth.

 

I provide also a 3D reconstruction of the scene in the preprint although some people  may find it easier to watch a video instead.

 

 

Even after completion of the analysis there are  many open questions – where is the original headshot? There are numerous similar images at various image archives while I haven’t found the original so far. Any pointer would be greatly appreciated.

 

 

Even as there are now reasonable doubts on the image, Prince Andrew could have have met Virginia Giuffre. Maybe like an artist is painting a scene from memory, this photograph could be showing a real scene although not in a physical sense.

So, to repeat my last sentence in the paper – this photograph remains an unresolved but symbolically charged fragment within a complex story of abuse, memory, and contested truth.

Fragen und Antworten zur Staatsräson

Warum steht der Begriff „Staatsräson“ nicht ausdrücklich im Grundgesetz, wenn er doch angeblich das oberste Interesse oder Prinzip beschreibt, nach dem ein Staat handelt, um sein Bestehen, seine Ordnung und seine Sicherheit zu wahren?

– Ursprünglich wurde der Begriff in der Frühneuzeit geprägt, etwa durch Niccolò Machiavelli und später Giovanni Botero oder Richelieu.
– Er diente zur Legitimation staatlicher Machtpolitik, oft losgelöst von ethischen oder rechtlichen Maßstäben.
– In der Moderne ist er normativ begrenzt – d. h. im demokratischen Rechtsstaat muss Staatsräson mit Recht, Moral und Verfassung vereinbar sein.

Also ist Staatsräson das, was ein Staat für unbedingt notwendig hält, um sich selbst zu schützen und zu erhalten. Müsste in das nicht doch in das Grundgesetz?

Das Grundgesetz ist eine rechtsstaatliche Verfassung – kein Machtinstrument. Das Grundgesetz von 1949 wurde bewusst als Gegenentwurf zur NS-Diktatur geschaffen. Es soll:
– Macht begrenzen, nicht rechtfertigen,
– die Grundrechte des Einzelnen schützen, und
– Recht und Moral über staatliche Interessen stellen.
Ein Begriff wie „Staatsräson“, der traditionell die Zwecke des Staates über Recht und Moral stellt, passt nicht zu einer rechtsstaatlichen, demokratischen Verfassung wie dem Grundgesetz.

Enigma of Organismal Death

I asked ChatGPT-4 for more references around the 2024 paper “Unraveling the Enigma of Organismal Death: Insights, Implications, and Unexplored Frontieres” as Tukdam continues to be a hot topic. Here is the updated reading list

1. Organismal Superposition & the Brain‑Death Paradox
Piotr Grzegorz Nowak (2024) argues that defining death as the “termination of the organism” leads to an organismal superposition problem. He suggests that under certain physiological conditions—like brain death—the patient can be argued to be both alive and dead, much like Schrödinger’s cat, creating ethical confusion especially around organ harvesting. https://philpapers.org/rec/NOWOSP

2. Life After Organismal “Death”
Melissa Moschella (2017, revisiting Brain‑Death debates) highlights that even after “organismal death,” significant biological activity persists—cells, tissues, and networks (immune, stress responses) can remain active days postmortem. https://philpapers.org/rec/MOSCOD-2

3. Metaphysical & Ontological Critiques
The Humanum Review and similar critiques challenge the metaphysical basis of the paper’s unity‑based definition of death. They stress that considering a person’s “unity” as automatically tied to brain-function is metaphysically dubious. They also quote John Paul II, arguing death is fundamentally a metaphysical event that science can only confirm empirically. https://philpapers.org/rec/MOSCOD-2

4. Biological Categorization Limits
Additional criticism comes from theoretical biology circles, pointing out that living vs. dead is an inherently fuzzy, non-binary distinction. Any attempt to define death (like in the paper) confronts conceptual limits due to the complexity of life forms and continuous transitions. https://humanumreview.com/articles/revising-the-concept-of-death-again

5. Continuation of Scientific Research
Frontiers in Microbiology (2023) supports the broader approach but emphasizes that transcriptomic and microbiome dynamics postmortem should be more deeply explored, suggesting the paper’s overview was incomplete without enough data-driven follow-up https://pmc.ncbi.nlm.nih.gov/articles/PMC6880069/

Otto Hahn, Lise Meitner und Fritz Straßmann

Hier zur Erinnerung ein Video mit Otto Hahn (1879-1968), Lise Meitner (1878-1968) und Fritz Straßmann (1902-1980) im Gespräch, eine historische Aufnahme aus dem Januar 1960.

Nur Otto Hahn bekam einen Nobelpreis, obwohl unstrittig alle an der Entdeckung der Kernspaltung beteiligt waren.

https://www.ndr.de/geschichte/ndr_retro/Gespraech-mit-Otto-Hahn-Lise-Meitner-und-Fritz-Strassmann-,ausersterhand130.html

Es fällt auf, wie zuvorkommend in der Diskussion immer auch die Leistung von anderen anerkannt wird, die eigentlich demütige Grundeinstellung aller, in der nicht die Selbstdarstellung sondern der Erkenntnisgewinn die treibende Kraft war.

Are we really thinking at 10 bits/s?

There is a funny paper at arXiv, that is now published in Neurology. It claims to have found a

neural conundrum behind the slowness of human behavior. The information throughput of a human being is about 10 bits/s. In comparison, our sensory systems gather data at ~10^9 bits/s. The stark contrast between these numbers remains unexplained and touches on fundamental aspects of brain function: What neural substrate sets this speed limit on the pace of our existence? Why does the brain need billions of neurons to process 10 bits/s? Why can we only think about one thing at a time?

If there are really two brains, an “outer” brain with fast high-dimensional sensory and motor signals and an “inner” brain that does are the processing?  My inner brain says this is a huge speculation.
