Milestone In Inorganic Chemistry

by George Barany and Friends

This "mid-week level" puzzle was released on a date of particular significance to the puzzle's honoree, who is pictured to the right (photo circa 1989). After completing the puzzle (spoiler), learn more about the honoree, and about the puzzle itself, by clicking here for our "midrash." 

Click here to view or download the "main" puzzle in PDF format; here to download it as a puz file; here to download it as an ipuz file [requires the free Puzzazz app to solve]; here to solve the puzzle interactively (thanks to Jim Horne); here for the solution. Some familiarity with the Periodic Table will certainly come in handy as you work your way through the puzzle. Click here for a version of the puzzle in which about a third of the clues have been rewritten for solvers who are not academic chemists, here for the puz file, here to download it as an ipuz file, and here for interactive play [the theme clues and the overall solution are the same]. I am grateful to Marcia Brott, Jeff Chen, Noam Elkies, Michael Hanko, Brent Hartzel, Martin Herbach, Alex Vratsanos, and Letitia Yao from our usual beta testers, as well as special guest beta testers William Brennessel, Mark Lipton, and Andrew Myers, for helping to vet and significantly improve both the chemical and cruciverbalistic qualities of this puzzle.
