Frohen Tag der Deutschen Einheit!

You’re a Cyclist Who Was Just Struck by a Car Driver. Here’s Why It Was Your Fault You were riding during rush hour. Why were you riding then? There are way too many cars on the road. If you were commuting, you should have contact...

"The only people who should ride their bikes during the workday are bike messengers, who I also dislike. They weave, they bob—it’s inappropriate. Bike messengers need to do what drivers do: go straight, get pissed off, and hate everyone."

Although the approaches are different, I believe that science and art are both rooted in the human desires to make sense of this world and make it a better place for mankind.

Physics can still make it into art exhibitions. I am glad that some people understand that science is a cultural (= human) endeavour which carries an intrinsic beauty in its expressions and insights.

Sabine Hossenfelder retweets infamous white supremacist Jordan Lasker aka Crémieux who says I highly recommend unfollowing and blocking snark/sneering accounts They bring negative value into your feed They're incurious, angry, and they make tons of unforced errors that normal people don't make just by virtue of being kinder and more charitable

I assume you're all as shocked as I am

This essay traces the long and turbulent history of American booksellers who have faced censorship, harassment, and even violence for defending the freedom to read. Through vivid anecdotes and historical cases-from undercover stings in the early 1900s and legal battles over “obscene” literature, to FBI surveillance of Black bookstores and bomb threats against feminist and LGBTQ+ shops-the author illustrates how bookstores have repeatedly become battlegrounds in the fight for civil liberties and free expression. Despite intimidation from both government and private groups, booksellers have pushed back, shaping legal precedents and rallying communities to defend First Amendment rights. The essay ultimately calls on readers to recognize bookstores as “arsenals of democracy” and to support their ongoing role in safeguarding intellectual freedom.

Booksellers have faced censorship and harassment defending the freedom to read. Celebrate your local bookstore and support their ongoing role in safeguarding intellectual freedom.

A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.

Auschwitz was at the end of a long process. It did not start from gas chambers.

This hatred was gradually developed by humans. From ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder.

Auschwitz took time.

Niche gripe:

I think there are a lot of people who get good at something via a combination of natural talent and grind, who then grow up to write books about how anyone can do it using a few simple tricks.

Science and math people are especially guilty of this.

And we "only" need to put some SQUIDs near neutrino beams.

In my new paper in collaboration with Jack D. Shergold we discuss a new, model independent way to provide constraints on neutrino charges. Interestingly, that could also be used to competitively constrain new long-range interactions between neutrinos and other SM particles.

Constraining neutrino charges at beam experiments We propose a new method to constrain neutrino charges at neutrino beam experiments. Uncharged in the Standard Model, evidence for a neutrino electric charge would be a smoking gun for new physics, she...

Paper day!

It is a common believe that neutrinos have no electric charge. But that is a question which has to be answered in experiment. There are indeed very strong constraints which are nevertheless often model dependent.
