Faraday:

(1791-1867) English scientist contributed to the study of electromagnetism & electrochemistry; main discoveries include the principles underlying electromagnetic induction, diamagnetism & electrolysis.  Despite having minimal formal education was one of the most influential scientists in history.  His research on the magnetic field & current established the concept of the electromagnetic field.  His inventions of electromagnetic rotary devices established the electric motor technology, and his efforts made electricity a practical technology.

 

Morphology:

branch of biology dealing with the study of the form & structure of organisms and specific structural features, including aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology and the form and structure of the internal parts (bones & organs).  In contrast to physiology, which deals primarily with function, Morphology studies of gross structure of an organism, its component parts or of a group of 1 or more populations of an organism.

 

Systematic:

Marked by a methodical plan or procedure and repeatability.  [Not 'systemic' which means "system wide."]  Done or acting according to a fixed plan or system; methodical.
 

Physiognomic:

assessment of character or personality from a person's outer appearance, especially the face; may also refer to the general appearance of a person, object, or terrain without reference to its implied characteristics, as in the physiognomy of an individual plant or a plant community.  In botany it is classification based on external appearance of vegetation, vertical structure & growth forms of the dominant group.  It can be applied to communities (locally related plants) showing emergent traits of the community.  It includes the classification of plants based on their visible structure, aspect or appearance
