Among many things, Luis Alvarez invented a detonating device for the atomic bomb. The acclaimed physicist also co-discovered the East/West effect of cosmic rays, which is what led him to study nuclear physics in depth. During World War II, he created three radar systems including a high-altitude bombing system, a blind landing system and an early warning system.Continue Reading
Luis Alvarez graduated from the University of Chicago, eventually earning his PhD at the school in 1932. He later became part of the Manhattan Project, a government project to invent a nuclear weapon. Alvarez's discoveries and contributions won him the Nobel Prize in Physics in 1968. Alvarez held 22 patents during his lifetime and was also famed for developing a golf training machine specifically for President Eisenhower.
Later on in his life, he aided an exploration to find unearthed chambers in the pyramids in Egypt. Alvarez became interested in archaeology and geology through this expedition and began working with his son, a geology professor at Berkeley, to study dinosaurs and their extinction. Alvarez and his son were the first to publish the theory that dinosaurs may have become extinct due to an asteroid hitting the Earth more than 60 million years ago.Learn more about Inventions
A digital device is an electronic device which uses discrete, numerable data and processes for all its operations. The alternative type of device is analog, which uses continuous data and processes for any operations. Any device which uses a computer of any sort in its operations is at least partially digital.Full Answer >
Although scissors are popularly thought to have been one of Leonardo da Vinci's inventions, earlier examples of the device have been dated to between 3000 and 4000 years ago. While a single original inventor is not known, the earliest scissors are attributed to people of the Middle East.Full Answer >
Since the 1st century when Romans experimented with magnifying small objects by looking at them through glass, the microscope has changed considerably with modern versions of the device capable of presenting three-dimensional images of objects at the sub-atomic level. The most notable advances in microscope technology occurred in the 19th century.Full Answer >
Albert T. Marshall of Brockton, Mass., was issued a patent on Aug. 8, 1899 for his household refrigeration device. Several other refrigeration systems had been invented previously, but Marshall’s was the first to be patented in the United States.Full Answer >
