A rotating ball casts a shadow that perfectly matches a mass on a spring, revealing how circular motion and simple harmonic motion are linked. A visual proof of sine-wave physics in action.
A rotating ball’s shadow moves like a mass on a spring-showing that circular motion projects into simple harmonic motion, a clean visual of sine-wave physics.
@YourSkinCareBot Had both Lasik and Lasek done. Had I had Lasek done first I would never have had it done again. Recovery sucked. Lasik was way better recovery. And for those wondering it was 12 years between the ops. Still the best think I have ever done. worth every penny.
@polaleeks@starheal Sounds like my Moscow fun. Got pulled for a search. Band and crew headed on without me. Wouldn't get on the plane till I got there! Ran the full length and down 3 floors!
Happy birthday to Hermann von Helmholtz. Born today in 1821, he was a German physician and physicist whose work spanned physiology, optics, acoustics, and thermodynamics.
He is best known for formulating the law of conservation of energy, establishing that energy can neither be created nor destroyed, only transformed. Helmholtz also invented the ophthalmoscope, revolutionising eye medicine, and made fundamental contributions to the understanding of vision, hearing, and nerve conduction. His interdisciplinary approach bridged physics and physiology, making him one of the 19th century’s most influential scientists.
The Fourier series is a way to represent any periodic function as a sum of simple sine and cosine waves.
In essence, it breaks down complex signals into a combination of basic trigonometric functions, making it a powerful tool in mathematics, physics, and engineering for analyzing waveforms, heat transfer, vibrations, and more.
