✨ Apparent Magnitude (V) – The Brightness We See! ✨ Ever wonder why some stars shine brighter than others? It all comes down to apparent magnitude (V)—a measure of how bright a star appears from Earth, no matter its actual size or distance. Here’s what makes it fascinating: 🔭 Lower magnitude = Brighter star → A star with V = 1 is much brighter than one with V = 6! 💡 It’s one of the most reliable measurements in astronomy—what we see is what we record! 📡 Unlike other cosmic properties, apparent magnitude doesn’t need complex models—just a telescope and precise photometry. 🌍 But beware! Atmospheric distortion and light pollution can interfere with what we see. ✨ So next time you gaze at the stars, remember—what appears bright might just be a cosmic illusion! #AstronomyFacts #ApparentMagnitude #Stargazing #AstroAthens #ScienceIsAwesome #SpaceExploration #NightSky

Tesla Zero Electric Spin Top: The black disk of this amazing and unique top contains a strong dipole magnet which becomes the rotor in this alternator set up. In accordance with Faraday’s law, the rapidly changing magnetic field of the spinning top induces an AC current in the 1000 turn copper coil in the base. The intensity of the light emitted from the 3 LEDs in the base indicates how much current is being generated- and the base is composed of transparent resin that serves as a light pipe to distribute the emitted light via internal reflection. From a limited production run by artist and maker Tobi Lee and I’m lucky to have it in my collection. ➡ Follow the link in my profile for info on where to get many of the amazing items featured here on @physicsfun #physics #magneto #alternator #spinningtops #desktoy #indiegogo #physicstoy #physicsfun #faraday #faradayslaw #tesla #magneticinduction #science #scienceisawesome
