Miracles come in different forms. Some are fabulous, others are real. For example, launching a person into space. In 1961, many perceived this flight as a technical miracle. It is no coincidence that S.P. Korolev, the chief designer under whose leadership this project was carried out, called this and similar developments “fantasy in drawings.” Similar real miracles often happen today. And sometimes we are not even surprised by them. Each such “miracle” is a concentrate of an ingenious idea, precise calculation, excellent technology and hard work. Such miracles are worth being proud of, they are worth learning from. The next book in the series tells about one hundred of the most amazing discoveries, developments and inventions of the 20th and 21st centuries.
