The correct answer is: None of the above.
Harry R Jordan, Buckminster Fuller, Jack Smith, and Jan Timmer are all notable figures in their respective fields, but none of them are known to have made the statement “The three most important inventions of this century are the nuclear bomb, the high yield hybrid speed, and the computer.”
The statement is most likely apocryphal, and its true author is unknown. It has been attributed to a variety of sources, including Albert Einstein, Winston Churchill, and Thomas Edison. However, there is no evidence that any of these individuals actually said it.
The statement is likely based on the idea that the nuclear bomb, the high yield hybrid speed, and the computer are three of the most important inventions of the 20th century. The nuclear bomb is a weapon of mass destruction that has the potential to kill millions of people. The high yield hybrid speed is a type of engine that is more efficient than traditional engines. The computer is a device that can be used for a variety of purposes, including communication, entertainment, and education.
While these inventions are certainly important, it is difficult to say definitively whether they are the three most important inventions of the 20th century. Other inventions that could be considered for this title include the automobile, the airplane, the television, and the internet.
Ultimately, the question of which inventions are the most important is a matter of opinion. There is no right or wrong answer, and different people will have different opinions.
