同学们都知道毫米吧,它可能是我们印象中非常小的长度单位了。其实,还有更小的呢,比如丝米。10 个丝米才等于1毫米。而5丝米大约只有几根头发那么粗。可就这5丝米的差距,却决定着100 多年前电话机发明的成与败。19世纪末,英国医生贝尔宣布他发明了电话机,一时轰动科学界。不料,就在他申请这项发明专利之后,科学家莱斯向美国最高法院提出了对贝尔的控诉,声称电话机是他发明的,发明权归他所有。
The classmates all know mm, it may be a very small unit of length in our impressions. In fact, there are smaller, such as silk. 10 silk is equal to 1 millimeter. The 5 silk about only a few hair so thick. However, the gap between these five silk meters determines the success or failure of the telephone invented more than 100 years ago. The late 19th century, the British doctor Bell announced that he invented the telephone, a moment of sensation in the scientific community. Unexpectedly, just after he applied for the invention patent, the scientist Rice presented a complaint to Bell to the Supreme Court of the U.S., claiming that the telephone was invented by him and the invention right belongs to him.
