(no subject)

I have been exposed to many mnemonics in my life and some of them I have actually successfully memorised but for the most part they are of no practical use to me. Either they are for something I already remember without help (SOHCAHTOA, PEMDAS, which months have 30 days) or they're for something I don't ever really care about (taxonomic ranks). (does the fifth of novemeber rhyme count as a mnemonic? because that one's both)

The only ones I'm glad I learned are the SI prefixes ones from this xkcd comic
