If the electrons pass by a solenoid, the pattern is shifted - even though the magnetic field is zero everywhere outside this coil. #SciArt #MathArt #Physics25 Jun 2026 18:06 +0000at://did:plc:3lizeiwo7mgrgypp3hf4bxxz/app.bsky.feed.post/3mp4zgaya222uhttps://bsky.app/profile/elkement.art/post/3moq6svioek25I've drawn another hyperboloid, now the two-part version: The Mass Shell of physics, relativistic energy as a function of momentum (two dimensions). #physics #mathsky #mathart #sciart Colored pencils on black paper, traditional descriptive geometry.20 Jun 2026 15:38 +0000at://did:plc:3lizeiwo7mgrgypp3hf4bxxz/app.bsky.feed.post/3moq6svioek25https://bsky.app/profile/elkement.art/post/3molam225u22jExcellent article about one of my favorite books of all time!
