Mathilde Carmen Hertz
Mathilde Carmen Hertz (14 January 1891 – 20 November 1975) was a biologist, and was one of the first influential women scientists in the field of biology and a pioneer in the field of comparative psychology. Working in Germany, her career started to unravel in 1933 due to her Jewish ancestry.Kressley RA, Jaeger S. 2003. Rediscovering a missing link: The sensory physiologist and comparative psychologist Mathilde Hertz (1891-1975). ''History of Psychology'' 6(4): 379-396. DOI:10.1037/1093-4510.6.4.379 She was the younger daughter of the famous physicist Heinrich Rudolf Hertz. Biography Mathilde Hertz was born on 14 January 1891 in Bonn, Germany. Her father, Heinrich Hertz, died in 1894 when Mathilde Hertz was still very young. Hertz was born into a wealthy and well-educated family. After finishing secondary schooling, she received training in fine arts and worked as a sculptor. One of her first jobs involved reconstructing fossilized teeth at the German Museum. Ludwig ...

Comparative Psychology
Comparative psychology refers to the scientific study of the behavior and mental processes of non-human animals, especially as these relate to the phylogenetic history, adaptive significance, and development of behavior. Research in this area addresses many different issues, uses many different methods and explores the behavior of many different species from insects to primates. Comparative psychology is sometimes assumed to emphasize cross-species comparisons, including those between humans and animals. However, some researchers feel that direct comparisons should not be the sole focus of comparative psychology and that intense focus on a single organism to understand its behavior is just as desirable; if not more so. Donald Dewsbury reviewed the works of several psychologists and their definitions and concluded that the object of comparative psychology is to establish principles of generality focusing on both proximate and ultimate causation.Dewsbury, D. (1984). ''Comparative Psy ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Raven
A raven is any of several larger-bodied bird species of the genus ''Corvus''. These species do not form a single taxonomic group within the genus. There is no consistent distinction between "crows" and "ravens", common names which are assigned to different species chiefly on the basis of their size. The largest raven species are the common raven and the thick-billed raven. Etymology The term "raven" originally referred to the common raven (''Corvus corax''), the type species of the genus ''Corvus'', which has a larger distribution than any other species of ''Corvus'', ranging over much of the Northern Hemisphere. The modern English word ''raven'' has cognates in all other Germanic languages, including Old Norse (and subsequently modern Icelandic) and Old High German , all of which descend from Proto-Germanic . Collective nouns for a group of ravens (or at least the common raven) include "rave", "treachery", "unkindness" and "conspiracy". In practice, most people use the more ...

Scientists From Bonn
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Medical Ultrasonography
Medical ultrasound includes diagnostic techniques (mainly medical imaging, imaging techniques) using ultrasound, as well as therapeutic ultrasound, therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g. distances and velocities) or to generate an informative audible sound. Its aim is usually to find a source of disease or to exclude pathology. The usage of ultrasound to produce visual images for medicine is called medical ultrasonography or simply sonography. The practice of examining pregnant women using ultrasound is called obstetric ultrasonography, and was an early development of clinical ultrasonography. Ultrasound is composed of sound waves with frequency, frequencies which are significantly higher than the range of human hearing (>20,000 Hz). Ultrasonic images, also known as sonograms, are created by se ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Carl Hellmuth Hertz
Carl Hellmuth Hertz (also written Carl Helmut Hertz, October 15, 1920 – April 29, 1990) was a German physicist known primarily for being involved in the development of inkjet technology and ultrasound technology. He was the son of Gustav Ludwig Hertz and great nephew of Heinrich Hertz. Biography Hellmuth Hertz was born October 15, 1920 in Berlin, Germany. His father was Gustav Hertz who, along with James Franck, was awarded the Nobel Prize in Physics 1925 for their experiments on inelastic electron collisions in gases. Gustav Hertz's uncle was in turn Heinrich Hertz, who first conclusively proved the existence of the electromagnetic waves. Hellmuth graduated from the elite Schule Schloss Salem boarding school in 1939 at the age of 19 years with the highest grade in mathematics and physics. The same year, he was conscripted into the German Army (Wehrmacht) and served as a soldier for Nazi Germany in World War II. In 1943 he was captured in the North African theatre by US ...

Nobel Prize
The Nobel Prizes ( ; sv, Nobelpriset ; no, Nobelprisen ) are five separate prizes that, according to Alfred Nobel's will of 1895, are awarded to "those who, during the preceding year, have conferred the greatest benefit to humankind." Alfred Nobel was a Swedish chemist, engineer, and industrialist most famously known for the invention of dynamite. He died in 1896. In his will, he bequeathed all of his "remaining realisable assets" to be used to establish five prizes which became known as "Nobel Prizes." Nobel Prizes were first awarded in 1901. Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace (Nobel characterized the Peace Prize as "to the person who has done the most or best to advance fellowship among nations, the abolition or reduction of standing armies, and the establishment and promotion of peace congresses"). In 1968, Sveriges Riksbank (Sweden's central bank) funded the establishment of the Prize in Economi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gustav Ludwig Hertz
Gustav Ludwig Hertz (; 22 July 1887 – 30 October 1975) was a German experimental physicist and Nobel Prize winner for his work on inelastic electron collisions in gases, and a nephew of Heinrich Rudolf Hertz. Biography Hertz was born in Hamburg, the son of Auguste (née Arning) and a lawyer, Gustav Theodor Hertz (1858–1904), Heinrich Rudolf Hertz' brother. He attended the Gelehrtenschule des Johanneums before studying at the Georg-August University of Göttingen (1906–1907), the Ludwig Maximilian University of Munich (1907–1908), and the Humboldt University of Berlin (1908–1911). He received his doctorate in 1911 under Heinrich Leopold Rubens.Mehra and Rechenberg, 2001, 197. From 1911 to 1914, Hertz was an assistant to Rubens at the University of Berlin. It was during this time that Hertz and James Franck performed experiments on inelastic electron collisions in gases, known as the Franck–Hertz experiments, and for which they received the Nobel Prize in Physics i ...
