密彻尔·法拉第(Michnel Faraday)在发现电磁感应后不久,在和首相罗伯特·皮尔(Robert Peel)谈及此问题时,皮尔问法拉第:“电磁感应是否有实用价值?”法拉第回答:“我不清楚,但我敢打赌,总有一天你的政府会为此征税的。”液晶的发表也有类似的故事,液晶是在1888年由奥地利科学家夫雷德利克·雷尼泽(Friedrich Reinitzor)发现的。他描述了一种特殊有机固体——胆甾基苯酸盐的性质,当加热时这有机固体变成混浊状态。继续加热它又变为透明液体。这种物质按现代分类叫做液晶。所有物质按惯例分为三种状态(或相)存在:固体、液体和气体。然而在一定温度范围内,某些有机化合物
Shortly after discovering electromagnetic induction, Michnel Faraday, talking to the Prime Minister Robert Peel, asked Pierre Fardla: “Is Electromagnetic Induction Practical?” Faraday replied: “I do not know, but I bet your government will someday tax it.” The release of the LCD has a similar story, with the LCD in 1888 by Austrian scientist Fredrik Rehnitz (Friedrich Reinitzor) discovered. He described the nature of a special organic solid, cholesterylbenzene, which turns cloudy when heated. Continue to heat it into a transparent liquid. This material is classified as liquid crystal by modern classification. All substances are conventionally divided into three states (or phases): solid, liquid, and gas. However, in certain temperature range, some organic compounds
