Wie öffnet man festsitzende #Schraubgläser, wenn einem fast die Hand abfällt? 🚴‍♂️🥫 Ich habe vor einiger Zeit mal einen #Hebelöffner zum Klemmen ausprobiert. Nach 2 Sekunden war er kaputt. Es gibt eine einfachere Lösung, die oft funktioniert. Neugierig auf weitere Details?

Upcycling: Schraubgläser öffnen mit einem Fahrradschlauch
Hat Euch schonmal ein fest sitzender Twist-off-Deckel in den Wahnsinn getrieben? Gerade bei eigenen Konserven sitzen die Deckel oft sehr fest. Wer die Konservengläser wieder zum Einwecken benötigt , möchte den Deckel...

Analytical Perturbative Construction of Initial Data for Binary Black Holes up to Third Order in Spin and Momentum
We analytically solve the constraints in General Relativity for two black holes with arbitrary momenta and spin up to third order in these parameters. We compute the location and geometry of the apparent horizon, which depend on the spins, momenta, relative orientation angles, and the separation between the black holes, and present the result in a coordinate-independent form. We also extract the ADM mass and the irreducible mass and verify their consistency. The final expressions are depicted i…

Evolutionary Links: From Gaia Neutron Star Binaries to Pulsar White Dwarf Endpoints
The discovery of wide, eccentric Gaia neutron stars (NSs) in binaries with still evolving (likely main sequence) companions offers a new probe of mass transfer and pulsar recycling beyond the compact-binary regime. We model their origins and fates using population synthesis with POSYDON and detailed binary evolution with MESA, contrasting two limiting prescriptions at Roche-lobe overflow (RLOF): enforced circularization versus explicitly eccentric mass transfer. Our MESA setups include updated …

Implementing the Quantum Approximate Optimization Algorithms for QUBO problems Across Quantum Hardware Platforms: Performance Analysis, Challenges, and Strategies
Quantum computers are expected to offer significant advantages in solving complex optimization problems that are challenging for classical computers. Quadratic Unconstrained Binary Optimization (QUBO) problems represent an important class of problems with relevance in finance and logistics. The Quantum Approximate Optimization Algorithm (QAOA) is a prominent candidate for solving QUBO problems on near-term quantum devices. In this paper, we investigate the performance of both the standard QAOA …

I made a poll to see what generation do programmers in the Fediverse belong. 1,184 of you participated, and this resulted in the following distribution:
82.88 of you reported being a Baby Boomer.
473.6 of you said you belong to Generation X.
532.8 of you said you are Millennials.
82.88 of you said you don't belong to any of these three.
I was surprised to see these many Generation Xers at 40%, vs Millenials at 45%.

Inferring cosmological parameters from galaxy and dark sirens cross-correlation
The number of observed gravitational wave (GW) events is growing fast thanks to rapidly improving detector sensitivities. GWs from compact binary coalescences like Black Holes or Neutron Stars behave like standard sirens and can be used as cosmological probes. To this aim, generally, the observation of an electromagnetic counterpart and the measurement of the redshift are needed. However, even when those are not available, it is still possible to exploit these "dark sirens" via statistical meth…
