Puh, da musste ich mich erstmal hinsetzen...

Am Ende hatte die Werkstatt nun neue Ersatzteile wie z.B. Gabel, Laufräder, Schutzbleche, Gepäckträger und sowas...

Und ich hatte jede Menge echten Schrott entsorgen dürfen.

Und ich hatte einen neuen tollen Ort und neue echt nette Leute aus Darmstadt kennen gelernt.

Wir haben gebogen, gezogen, gedreht, gerüttelt, bis die Sattelstütze irgendwann komplett hinüber war. Bewegt hatte sie sich leider trotzdem nicht. 🙃

Das war es dann für diesen schönen Rahmen. Er kam später in die Schrottkiste.
(Also vorher stand er ja schon bei den Schrotträdern, aber jetzt war er tatsächlich reif für die Schrottverwertung.)

Also WD40 drauf, dann kopfüber in so eine Schraubzwinge und den Rahmen von der Sattelstütze drehen...

Ging aber auch nicht.

Nächster Versuch: Den Rahmen heiß Föhnen mit so einem Heißluftgerät, damit er sich dehnt...

Hat aber auch nicht geholfen. Stattdessen ist die Sattelstütze nur noch mehr verbogen.

In der Selbsthilfewerkstatt meines Vertrauens, dem zentral in #darmstadt gelegenen zwanzig° (https://www.asta.tu-darmstadt.de/de/fahrradwerkstatt #zwanzig) durfte ich dann alles auseinander nehmen. Ich wollte ja nur den Rahmen behalten. Hat auch alles gut geklappt. Zwei Mal mußte ich mir kurz helfen lassen, weil Sachen geklemmt haben. Zum Schluss musste nur noch die Sattelstütze raus...

Die hat sich aber leider Null bewegt. 🤔

Im November bekam ich ein altes #Schrottrad geschenkt. Um mir daraus ein #Rennrad bauen zu können. Ich war sofort in die schönen Farben des Rahmens verliebt. 😍 Die Rahmengröße schien auch zu passen. So begann es: Das #manhattanproject

"Achieving AGI is the explicit goal of companies like OpenAI and much of the AI research community. It is treated as a milestone in the same way as building and delivering a nuclear weapon was the key goal of the Manhattan Project.

This goal made sense as a milestone in the Manhattan Project for two reasons. The first is observability. In developing nuclear weapons, there can be no doubt about whether you’re reached the goal or not — an explosion epitomizes observability. The second is immediate impact. The use of nuclear weapons contributed to a quick end to World War 2. It also ushered in a new world order — a long-term transformation of geopolitics.

Many people have the intuition that AGI will have these properties. It will be so powerful and humanlike that it will be obvious when we’ve built it. And it will immediately bring massive benefits and risks — automation of a big swath of the economy, a great acceleration of innovation, including AI research itself, and potentially catastrophic consequences for humanity from uncontrollable superintelligence.

In this essay, we argue that AGI will be exactly the opposite — it is unobservable because there is no clear capability threshold that has particular significance; it will have no immediate impact on the world; and even a long-term transformation of the economy is uncertain."

#Pioneering female #Chinese #American physicist Chien-Shiung Wu, who worked with Robert #Oppenheimer on the #ManhattanProject, was also the first to confirm #QuantumEntanglement – just 14 years after Albert #Einstein questioned the phenomenon. The largely forgotten achievement was included in a profile of Wu, one of the most influential experimental physicists of the 20th century, published in the December 2024 issue of Physics Today.

Wu is also believed to have been the only Chinese scientist involved in the Manhattan Project, the World War II initiative to develop an #AtomicBomb led by Oppenheimer, who affectionately referred to her as Jiejie, which means elder sister, the article said.

Wu’s experiment – detailed in a paper published in 1950 – was conducted before the #scientific community had fully grasped the significance of quantum entanglement, the article noted.

A road trip through New Mexico’s atomic past #travel #NewMexico #tourism #roadtrip #ManhattanProject

A road trip through New Mexico...

Today’s #TMYK (3/365) is also a #PSA: The guidelines for visiting the Trinity test site (location of the first nuclear weapon detonation) have been revised.

Visitors are now permitted only one day per year (used to be two) and the Alamogordo Caravan has been indefinitely canceled. 😭

There is good news, though. Signups are no longer required and it doesn’t seem there’s a cap on attendance.

I know where I plan to be on October 18!

#Americans outnumbered we #Canadians 12 to 1 back In the #War of 1812. Considering that, stalemate meant glorious victory for us & whitewashed #incompetence for the Americans. If we'd had those odds just imagine. Today they'd really in trouble because they only outnumber us 8 to 1. #ManhattanProject
