<\/p>\nThis is how my brain works. <\/p>\n
This morning, on my way to work, I remembered a t-shirt from a TV show we’re currently binging on with the word “sarcasm” written using element symbols from the periodic table:<\/p>\n
<\/p>\n
I then started to wondered about how I would go about finding all the words that would be written using element symbols. So when I got into work, I quickly hacked this together. Out of a starting word set of 58109 words, I find 7417 “periodic” words. The longest word, and one of several with the most component elements (13) is:<\/p>\n
Internationalisation, elements=In,Te,Rn,At,I,O,Na,Li,S,At,I,O,N <\/p>\n
Other amusing ones are: <\/p>\n
Inarticulateness, elements=In,Ar,Ti,Cu,La,Te,Ne,S,S
\nSupersaturation, elements=S,U,P,Er,S,At,U,Ra,Ti,O,N
\nConsciousnesses, elements=CO,N,Sc,I,O,U,Sn,Es,Se,S
\nProcrastination, elements=Pr,O,Cr,As,Ti,Na,Ti,O,N
\nHyperinflation, elements=H,Y,P,Er,In,F,La,Ti,O,N
\nFalsification, elements=F,Al,Si,F,I,Ca,Ti,O,N,S
\nPerniciousness, elements=P,Er,Ni,C,I,O,U,Sn,Es,S
\nPerambulations, elements=P,Er,Am,B,U,La,Ti,O,N,S
\nPontifications, elements=Po,N,Ti,F,I,Ca,Ti,O,N,S
\nHallucinations, elements=H,Al,Lu,C,In,At,I,O,N,S
\nVoluptuousness, elements=V,O,Lu,Pt,U,O,U,Sn,Es,S
\nSensationalism, elements=Se,N,S,At,I,O,Na,Li,Sm<\/p>\n
And many, many more.<\/p>\n
I then added a little tweak to filter out words that use repetitions of elements, and that brings down the number of “periodic” words to 5483. In that case, the longest word, and one of several with the most component elements (10) is:<\/p>\n
Reclassification, elements=Re,Cl,As,Si,F,I,Ca,Ti,O,N<\/p>\n
