The paper also shows that using a 3D model of magnetic fields dynamically evolved with the cosmic web does not give the same answers one can get using instead a simpler semi-analytical description of random magnetic fields (as usually in the literature).Also: that the magnetic horizon naturally arise for the same primordial magnetic field model which we independently selected a couple of years ago based on entirely different data-> https://mastodon.social/@franco_vazza/113519951147357770

I made some smaller versions of my new #physics inspired ink paintings. You can find them in my shop. All originals, ink on yupo, one of each https://artologica.etsy.com #art #sciart #painting
#PhysicsFactlet I haven't made a single scientific animation in months. I just don't have the mental space right now.But I am preparing a series of lectures on scattering for the Plasmonica 2026 School (https://www.plasmonica.it/2026school/), and it feels like a good excuse to make a few new ones.This one shows a simple finite element simulation of a pulse scattering on a small dielectric obstacle.#Physics #Optics #Scattering #Diffraction
Edit: I've had lots of wonderful people impart their knowledge and spark curiosity about science. This is all still very new to me but we're learning and that's good! Hello chemists and physicists of Mastodon!In my next assignment I have to create a 3D image of a molecule (which I've done) and then I have to label this molecule where we might find H-bonding and London forces. Just one example of each.I think I understand H-bonding, but when it came to studying London forces I just hoped it wouldn't come up.Well. It has.I don't understand London forces at all so I have no idea how to even attempt to label a bond as a London force or not. Is it not all of the bonds? At the moment I just have to randomly guess...#AskFedi #Chemistry #Physics
Pretty cold. Discoveries I made this morning:EVA rubber boots are no longer flexible and difficult to wear until your feet warm them up.LCD displays stop working.The fancy microcontroller thermometer had an integer overflow and showed +64°C when it was... I guess -31 or 32? 😆 The -25°C winter wiper fluid is now solid, but it shouldn't damage the cars as it has contracted rather than expanded like water does.The barn cat is still alive and got warm water and leftover porridge.LRT reports -34°C in nearby Ukmergė and that diesel engines can't run on jelly. Apparently LPG vehicles had problems too, not enough Propane in the mix: https://www.lrt.lt/en/news-in-english/19/2825089/lithuania-records-lowest-temperatures-in-30-years-cold-disrupts-public-transport#Lithuania #Cold #Winter #Diesel #Physics #Electronics
