Gaurav on Instagram: "日本利用壓電磁磚將腳步轉化為電能。這些瓷磚捕捉來自你腳步的動能。當你行走時,你的重量和動作會對瓷磚產生壓力。磁磚會輕微彎曲,從而產生機械應力磁磚內部的壓電材料將這種應力轉化為電能。每一步都會產生少量電荷,而數百萬步結合在一起就能產生足夠的電力來驅動LED燈、數位顯示器和感測器。在像澀谷車站這樣繁忙的地方,每天大約有240萬個腳步為此系統作出貢獻。這些電能可以被儲存或立即使用,從而減少對傳統電力來源的依賴,並支持可持續的城市基 3,316 礎設施。這個方法將日常運動轉化為實用的可再生能源 #日本#知識#事實#你知道嗎#推薦#科技 #創"

Astronomy | Space | Universe on Instagram: "The first-ever direct visualization of an electron’s orbit inside a hydrogen atom. It's not a single particle captured in motion, but rather a representation of the electron's probability cloud—the area where it is most likely to be found. This groundbreaking image offers a tangible glimpse into the strange world of quantum mechanics and a powerful testament to the advancements in modern physics. It's a profound reminder of the unseen universe that exi
