Mazurs Version of Janet's "Lemniscate" Formulation
Janet's lemniscate formulation periodic table as modified by E.G. Mazur in his Graphic Representations of the Periodic System during One Hundred Years (1974), cited in Punyashloke Mishra's The Role of Abstraction in Scientific Illustration: Implications for Pedagogy (1999) republished in Carolyn Handa's Visual Rhetoric in a Digital World: A Critical Sourcebook", from the Island94 blog, here:
Year: 1974 | PT id = 267, Type = formulation 3D |
Mazurs Wooden Version of Mendeleev's Periodic Table
There is a posting in the The Elements Unearthed blog by David V Black concerning a view of the Marzus archive:
"My biggest discovery this week has been a collection in our archives of the notes of Edward Mazurs, who wrote the definitive work on classifying different systems of periodic tables in 1957 with a revised edition in 1974 (Graphic Representations of the Periodic System During One Hundred Years, University of Alabama Press). He collected articles and wrote extensive, detailed notes on every version of the periodic table he could find as it developed from its start in the early 1860s with the work of de Chancourtois through 1974. All of those notes have been donated to Chemical Heritage Foundation and fill up ten binders, with meticulous drawings, charts, tables, and frequent additions and changes. There are also some pieces of the original artwork prepared for the book, and a wooden model of the periodic table Mazurs built himself. "
Year: 1974 | PT id = 299, Type = formulation spiral 3D misc |
Mazurs' PT Formulation Analysis
In his 1974 book Edward G. Mazurs (2nd edition) Graphic Representations of the Periodic System During One Hundred Years, University of Alabama Press gives a comprehensive analysis of periodic table formulations.
Mazurs identifies most PT formulations as being:
- Spiral
- Plane lemniscate
- Concentric circles
- Helix on a cylinder
- Helix on a cone
- Space lemniscate
- Space concentric circles
Year: 1974 | PT id = 886, Type = element |
Discovery of Seaborgium
Sg
Seaborgium, atomic number 106, has a mass of 271 au.
Synthetic radioactive element.
Seaborgium was first observed in 1974 by A. Ghiorso et al.
Year: 1974 | PT id = 1058, Type = formulation spiral |
Mazurs' Redrawing of Stedman's Formulation
An spiral formulation by Mazurs, cited as being after Janet (1928). However, it is actually, it is after Stedman (1947).
In an article Bull. Hist. Chem., VOLUME 34, Number 2 (2009) O.T. Benfey writes:
"After we had developed our own [Periodic Snail] spiral design, we found that E. G. Mazurs had published a spiral with a separate protrusion for the lanthanides which, under the image, he misleadingly ascribed to Charles Janet in 1928, the same year that Janet had published a simple circular form also shown by Mazurs. The Mazurs diagram with the lanthanide protrusion was reprinted in [the journal] Chemistry. However, [Philip] Stewart informed me that the Mazurs figure bears no resemblance to the Janet diagram he indicated nor to any other of his designs. Detailed references given a few pages later by Mazurs suggested correctly that the spiral derives from Stedman and is so identified and depicted by van Spronsen. The Mazurs diagram is a mirror image of the Stedman spiral, updated to include elements discovered since 1947." [For references, see the article.]"
Mazurs (p. 77) writes:
"Subtype IIIA3–1a Helix on a modified cone. The transition and inner transition elements have special revolutions in the form of loops. This table, originated by Stedman in 1947 is not a successful one."
