Important scientific and technological achievements of the 20th century
The 20th century was a 100 years of rapid progress in science and technology, and a bumper harvest of scientific and technological achievements. During this period, many modern scientific and technological achievements have produced huge, even complete changes in our clothing, food, housing, transportation, medical care, information exchange, and even our understanding of the universe... and so on. Many scientific and technological achievements that have been realized today seemed to be just distant fantasies at the beginning of the 20th century, because at that time, even a small paper clip for clipping paper had just been patented.
Looking back at the 20th century, which is about to end, we will definitely realize that these colorful and even almost magical scientific and technological achievements are quite precious and are the result of the accumulation of wisdom and hard work of several generations. Just achieved.
