As a Hollywood film star, she was called "the most beautiful woman in the world". What she was less known for was her scientific thinking ability. During World War I, Lamarr quietly co-invented the technology that would be the precursor（前身）to Bluetooth, Wi-Fi and other systems we rely on today. She had a natural curiosity about the world around her. As young as 5, she would spend time taking apart and rebuilding her music box to understand how it worked. At 16, she got her first film role and quickly became an international icon（偶像）. As her acting career continued to take off. World War II broke out. Lamarr became restless, feeling that she should do more to contribute to the Allies' war efforts. "Lamarr said that she did not feel very comfortable, sitting there in Hollywood and making lots of money when things were in such a state," says George Antheil. Together with Antheil, Lamarr came up with a groundbreaking new form of wireless communication known as Spread Spectrum（频谱）. The concept was to create a wireless signal that could travel quickly from frequency to frequency. But the military refused to use it in their war efforts. The technology sat unused for years, until one day in the 1960s, the military accepted it and called the system "Spread like Wildfire". Hedy Lamarr played the role she was expected to play in Hollywood—a beautiful star on the big screen. And without her, communication could look completely different today. Lamarr's experience can serve as a reminder：Pursue your talents and passions. Not only will the world be better for it, but every pioneer who challenges the old will pave the way for others to follow. 【译文欣赏】 海蒂·拉玛习惯于因美貌而备受赞赏。作为好莱坞电影明星，她被誉为“世界上最美丽的女人”。但她鲜为人知的是其科学思维能力。在第一次世界大战期间，拉玛悄悄地与人共同发明了一项技术，这项技术成为了如今我们所依赖的蓝牙、Wi-Fi 等系统的前身。 她对周围的世界有着天生的好奇心。五岁时，她就会花时间拆解并重新组装自己的音乐盒，以了解其工作原理。16 岁时，她获得了自己的第一个电影角色，并迅速成为国际偶像。随着她的演艺事业蒸蒸日上，第二次世界大战爆发了。拉玛变得焦躁不安，觉得自己应该为盟军的战争努力做出更多贡献。“拉玛说，当局势如此紧张时，她坐在好莱坞赚大钱，感觉很不舒服。”乔治·安泰尔说道。 拉玛与安泰尔一起发明了一种开创性的新型无线通信方式，称为扩频技术。其概念是创建一种能够在不同频率间快速切换的无线信号。但军方拒绝在战争中使用它。这项技术闲置多年，直到 20 世纪 60 年代的一天，军方才接受了它，并将其命名为“野火蔓延”系统。 海蒂·拉玛在好莱坞扮演了人们期望她扮演的角色———大银幕上的美丽明星。而没有她，如今的 ... ...
