ALAN FRANK wrote that he "found the Bilingual Palindromic Dictionary amazing. With regard to the eponyms list, Avogadro's number is more well-known than his hypothesis, and correct or standard renderings are Lot's wife, Planck's constant, Wheatstone bridge, and Zorro's mask. Personally, I find the eponyms more interesting than the mere possessions such as Banquo, Mary, and Zorro.

I also played around with the atomic formulas. Some of my results are in the attachment [below], which I did not think would survive native e-mail very well.

I came up with a few interesting atomic expressions. I started the first two by looking for elements with numbers divisible by 34 and 8 and the last one looking for one with a name ending with NIUM so that the sevens would cancel.

(14 - 15 + 2) x (12 - 9) x (21 + 13) (3 + 21) / 18 x 9 x (21 - 13) (14 x 5) - [square root of 16] (20-21) + 14 x 9 / 21 + 13

If you allow factorials, as I have generally seen in the rules for similar puzzles, 79 can be expressed as 7 + (15 - 12) x 41.

I came close on some others. 86 is the limit of

18 x (1 + 4) - [square root of (15 + 14)] 18 x (1 + 4) - [square root of (15 + [square root of 14])]

18 x (1 + 4) - [square root of (15 + [square root of [square root of 14]])]

Given the equations below, one would expect XENON to be solvable.

-24 + 5 x (-14 + 15 - 14) = 51 -24 - 5! + 14 x 15 - 14 = 52 -24 + 5! - 14 - 15 - 14 = 53 24 + 5 + 14 + 15 - [square root of 14] [approximately equal to] 54.3 2.4 x 5 + 14 + 15 + 14 = 55
