Möbius Strip

An early design of the recycling symbol

The figure was designed as a Möbius strip to symbolize continuity within a finite entity. I used the [logo’s] arrows to give directionality to the symbol. I envisioned it with the small edge or the point of the triangle at the bottom. I wanted to suggest both the dynamic (things are changing) and the static (it’s a static equilibrium, a permanent kind of thing). The arrows, as broad as they are, draw back to the static side. [Emphasis is mine.]

Ununpentium shell

Ununpentium, with a staggering hundred and fifteen protons in its nucleus, is the newest, soon-to-be-added, element in the periodic table. Unum is Latin for ‘one’, and Pent- is Greek for ‘five’, so the name of this synthetic super-heavy element literally means 1-1-5-ium. It lies right below Bismuth in the periodic table, and hence was once knows as eka-bismuth.

[Eka means ‘one’ in Sanskrit; here’s my earlier post about Sanskrit in the periodic table.]
