The INTERNET Database of Periodic Tables

There are thousands of periodic tables in web space, but this is the only comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Mark R. Leach Ph.D. The database holds information on periodic tables, the discovery of the elements, the elucidation of atomic weights and the discovery of atomic structure (and much, much more).

Politically Correct Periodic Table of the Elements

By Robert Rose of MIT, appearing in the I²R calendar. (We guess the date at 1995.)

From Craigslist:

"Instruments for Research and Industry, better known to scientists as I²R (eye-squared-are), was founded in the 1960s. Soon after, they started offering humorous, science and research themed calendars as part-catalog, part-advertising, part-promotional and completely entertaining material. I²R was a 'Profits for Peace' company. I²R donated a portion of their profits to charitable causes. (The time was the 1960s - 1970s, the Vietnam War era. I²R estimated how much of their business taxes were going to the Department of Defense and then they offset that with donations to charitable causes.)"

Text:

"To protect the health and weltare of the general public, we must eliminate all sources of toxicity, pollution and radloactivity. Isotopes and artificial elements should not be tolerated, nor should sources of greenhouse gases or causes of hypertension. Sexist nomenclature has no place in modern society. These requirements can be satisfied by making the indicated revisions to the periodic table of the elements.

"This whimisical Periodic Table of the Elements first appeared in the Journal of Irreproducible Results. It is reprinted (slightly edited) here."

The PC-PT identifies:

• T: Toxic Elenents
• S: Sexist Nomenclature
• G: Greenhouse Gas Source
• R: Radioactive Elements (not permitted)
• H: Hazardous Element (raises blood pressure)
• H: Halogens (not permitted)
• A: Artificial Elements (not permitted without prior approval)

Thanks to Eric Scerri for the tip!
