意大利物理学家马可尼(Manconi Guglielmo 1874～1937)是实用无线电报系统的发明人。他将电磁学原理应用于信息空间传输,从而开创了不用导线就能对无数接收机同时进行电波通讯的先河,奠定了几乎所有现代远距离无线电通讯的基础。为此,许多国家先后发行了纪念他的邮票,如图是卢旺达共和国发行的一组纪念邮票。 马可尼出生于意大利博洛尼亚,家道殷实,他没有上过大学,但他热爱物理学。1894年他和哥哥一起去阿尔卑斯山度假,在旅途中,他读到了赫兹的一篇论文,赫兹用实验证明了麦克斯韦提出的电磁波确实存在,并能以光速穿透各种物质。马可尼敏锐地意识到电磁波可以用来传播信息。他回到家中开始进行了实验。他采用一只增压感应线圈和一只发送端由莫尔斯键盘控
Italian physicist Marconi (Manconi Guglielmo 1874 ~ 1937) is the inventor of a practical wireless telegraph system. He applied the principle of electromagnetism to the transmission of information space, creating a precedent for simultaneous wave communication of countless receivers without wires, laying the groundwork for almost all modern long-range radio communications. To this end, many countries have successively issued stamps commemorating his visit, as shown in the set of commemorative stamps issued by the Republic of Rwanda. Marconi was born in Bologna, Italy, family well, he did not go to college, but he loves physics. In 1894 he and his brother went on a holiday in the Alps. During the trip, he read a Hertz essay. Hertz proved by experiments that the electromagnetic waves proposed by Maxwell did exist and penetrate all kinds of matter at the speed of light. Marconi keenly aware that electromagnetic waves can be used to spread information. He returned home and started the experiment. He uses a booster induction coil and a transmitter controlled by a Morse keyboard
