Willem Einthoven (21 May 1860 – 29 September 1927) was a Dutch medical doctor and physiologist. He invented the first practical electrocardiograph (ECG or EKG) in 1895 and received the Nobel Prize in Physiology or Medicine in 1924 for it ("for the discovery of the mechanism of the electrocardiogram").
The resolution of the problem was completely unknown at the time, and 't Hooft was unable to provide one. In 1969, 't Hooft started on his doctoral research with Martinus Veltman as his advisor. He would work on the same subject Veltman was working on, the renormalization of Yang–Mills theories. In 1971 his first paper was published. [3]
It is a method of defamiliarization of common sense. Problematization is a critical thinking and pedagogical dialogue or process and may be considered demythicisation . Rather than taking the common knowledge ( myth ) of a situation for granted, problematization poses that knowledge as a problem, allowing new viewpoints, consciousness ...
MLA Style Manual, formerly titled MLA Style Manual and Guide to Scholarly Publishing in its second (1998) and third edition (2008), was an academic style guide by the United States–based Modern Language Association of America (MLA) first published in 1985. MLA announced in April 2015 that the publication would be discontinued: the third ...
Graphical representation of Einthoven's triangle. Einthoven's triangle is an imaginary formation of three limb leads in a triangle used in the electrocardiography, formed by the two shoulders and the pubis. [1] The shape forms an inverted equilateral triangle with the heart at the center. It is named after Willem Einthoven, who theorized its ...
Problem structuring methods (PSMs) are a group of techniques used to model or to map the nature or structure of a situation or state of affairs that some people want to change. [1] PSMs are usually used by a group of people in collaboration (rather than by a solitary individual) to create a consensus about, or at least to facilitate ...
Morphological analysis or general morphological analysis is a method for exploring possible solutions to a multi-dimensional, non-quantified complex problem. It was developed by Swiss astronomer Fritz Zwicky . [ 1 ]
However, Einthoven needed an exact way of measuring the minute amounts of current. In 1897 a French electrical engineer, Clement Ader, invented the "string galvanometer", containing a tensioned string of quartz. In 1903, Einthoven modified Ader's machine, adding electrodes attached to the patients limbs and thorax.
