The apparent displacement, or difference of position, of an object, as seen from two different stations, or points of view. In contemporary writing parallax can also be the same story, or a similar story from approximately the same time line, from one book told from a different perspective in another book.
In 1838, Theodor Schwann and Matthias Schleiden were enjoying after-dinner coffee and talking about their studies on cells. It has been suggested that when Schwann heard Schleiden describe plant cells with nuclei, he was struck by the similarity of these plant cells to cells he had observed in animal tissues.
The first scientist who described cells is the English scientist Robert Hooke. In 1665, he discovered the cell when he observed tiny boxes from a slice of cork, basically barkâ¦ and named them 'cells'. He then created the cell theory. Hope that helps.
