In a previous video, we argued that typical notions of 'something' and 'nothing' don't really make sense according to modern physics. But many commenters objected to this idea, calling it a semantic game. Culture Vaults : Resonant Frequencies and the Human Brain. One of the great revelations of 20th century science is that all existence can be broken down into simple wave functions.
Every photon, energy emission, and elementary particle rings with its own unique wave signature. When we see a color, we are actually seeing a distinct frequency of visible light. When we hear a sound, our eardrums are actually being vibrated by subtle waves in the air molecules around us. Engineering. Chaîne de FlowScience FLOW-3D has many applications for the hydraulics industry, including modeling fish passages, dam breaks, spillways, avalanches, hydroelectric power and other water and environmental engineering challenges.Users can increase the capacity of existing infrastructure in hydropower plants, develop novel approaches to fish passages, design intakes that minimize head loss, develop improved forebay designs and tailrace flows, analyze scour and deposition and evaluate air entrainment.
