Hans Christian Ørsted

While preparing for an evening lecture on 21 April 1820, Hans Christian Ørsted made a surprising observation.

The recognition of electromagnetism, the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and

The method is named after its inventor, the Danish scientist Hans Christian Gram ( 1850 – 1938 ), who developed the technique while working with Carl Friedländer in the morgue of the city hospital in Berlin.

It is sometimes assumed that he found a relationship between electricity and magnetism, about two decades before Hans Christian Ørsted's 1820 discovery of electromagnetism.

However the exact relationship of the term Ahhiyawa to the Achaeans beyond a similarity in pronunciation is hotly debated by scholars, even following the discovery that Mycenaean Linear B is an early form of Greek ; the earlier debate was summed up in 1984 by Hans G. Güterbock of the Oriental Institute.

The initial discovery was made by Hans Geiger and Ernest Marsden in 1909 when they performed the gold foil experiment under the direction of Rutherford, in which they fired a beam of alpha particles ( helium nuclei ) at layers of gold leaf only a few atoms thick.

This cycle was the first metabolic cycle discovered ( Hans Krebs and Kurt Henseleit, 1932 ), five years before the discovery of the TCA cycle.

He took advantage of the infancy of the usage of electricity, especially the then-novelty of Hans Christian Oersted's discovery of electromagnetism, to his advantage.

More detailed electron microscopic comparisons between cyanobacteria and chloroplasts ( for example studies by Hans Ris ), combined with the discovery that plastids and mitochondria contain their own DNA ( which by that stage was recognized to be the hereditary material of organisms ) led to a resurrection of the idea in the 1960s.

Hans Spemann ( 27 June 1869 – 9 September 1941 ) was a German embryologist who was awarded a Nobel Prize in Physiology or Medicine in 1935 for his discovery of the effect now known as embryonic induction, an influence, exercised by various parts of the embryo, that directs the development of groups of cells into particular tissues and organs.

Kattwinkel's discovery inspired Professor Hans Reck to lead a team to Olduvai Gorge in 1913.

A previous mention of a Hans Island is found in Arctic Explorations: The Second Grinnell Expedition, 1853 ,’ 54 ,’ 55, by Elisha Kent Kane ( 1857 ), pages 317 – 319, making the year 1853 often cited as the date of the discovery and naming of Hans Island, including in the letter by the Danish Ambassador to Canada, published in the Ottawa Citizen, July 28, 2005.

With the discovery of the electroencephalogram ( EEG ) in 1929, Hans Berger revealed that one could measure the electrical activity of the human brain by placing electrodes on the scalp and intensifying the signal.

The history of brain – computer interfaces ( BCIs ) starts with Hans Berger's discovery of the electrical activity of the human brain and the development of electroencephalography ( EEG ).

Hanukoglu was awarded the first Hans Lindner Prize ( 1988 ) of the Israel Endocrine Society, and Lubell Award ( 1991 ) of the Weizmann Institute of Science for his elucidation of the structures of NAD / NADP coenzyme binding enzyme families, and his discovery of common NADP binding motifs in the structure of these enzymes.

First established in 1936, following Hans Merensky's discovery of significant alluvial diamond deposits on the north bank of the Orange River and the adjacent northern coastline.

The discovery of this is often attributed to a German gall bladder surgeon named Hans Kehr, but extensive studies into research he conducted during his life shows inconclusive evidence as to whether or not he actually discovered it.

The discovery was then published on October 25, 2001, in the scientific journal Science by Paul C. Sereno of the University of Chicago and National Geographic's Explorer-in-Residence, Hans C. E. Larsson from Yale University and the University of Toronto ( formerly a student at the University of Chicago ), Christian Sidor of the New York College of Osteopathic Medicine in Old Westbury, New York and Boubé Gado of the Institut de Recherches en Sciences Humaines in Niamey, Niger.

In a tract of 16 pages, published in 1859, Zantedeschi defended the claims of Gian Domenico Romagnosi to the discovery in 1802 of the magnetic effect of the electric current, a discovery which is usually accredited to Hans Christian Ørsted in 1820.
