Pronunciation: [hˈanz d͡ʒˈa͡ɪɡə] (IPA) 
The correct spelling for the name "Hans Geiger" can be confusing due to the pronunciation of the surname. The last name is pronounced as "Ghy-ger" and not like the word "gig". This is due to the German origin of the name where the letter "ei" is pronounced as "ay". The International Phonetic Alphabet (IPA) transcription for the name "Hans Geiger" would be /hæns ˈɡaɪɡər/, with the stress on the second syllable of "Geiger".
Hans Geiger was a German physicist who was born on September 30, 1882, and died on September 24, 1945. He is best known for his invention of the Geiger-Muller counter, a device used in detecting and measuring radiation. Geiger's contributions to the field of nuclear physics were substantial and played a crucial role in advancing our understanding of atomic structure and radioactivity.
In terms of a dictionary definition, Hans Geiger can be described as a German physicist and inventor who made significant contributions to the field of nuclear physics. He is primarily known for developing the Geiger-Muller counter, a device used for detecting and measuring radiation. This instrument, also known as a Geiger counter, revolutionized the field of nuclear science and provided researchers with a reliable and convenient means of studying and quantifying radiation.
Geiger's invention played a vital role in various scientific and practical applications, including radiation monitoring, medical diagnostics, and nuclear research. It operates by detecting ionizing radiation, such as alpha and beta particles, as well as gamma rays, by utilizing the ionization effect produced when charged particles pass through a gas-filled chamber within the counter. This device counts the number of particles or photons detected, thereby providing valuable data regarding the intensity and nature of the radiation.
Hans Geiger's contributions in the field of nuclear physics have left a lasting legacy. His invention, the Geiger-Muller counter, has become an essential tool for scientists, researchers, and professionals in a wide range of disciplines concerned with radiation detection and measurement.
The word Hans Geiger does not have an etymology of its own because it is a combination of two separate words representing a person's name. Hans is a German given name, while Geiger is a German surname. The etymology of Hans can be traced back to the Hebrew name Johanan, meaning graced by God. Meanwhile, the surname Geiger is derived from the German word geige, which means violin.
