Those things that help you remember... erm... stuff.
PeterTaylor would like to point out that they won't help you remember anything if you don't know what they're supposed to help you remember. I could Google them all, but it'll be quicker for people to annotate those they know.
Aww. AlexChurchill rather enjoyed the game of seeing a mnemonic and trying to figure out what it helped you remember. Maybe the contents of this page should be moved to /Answers? and leave just the mnemonics here, unencumbered by context, in the style of AnyoneKnowAnyCures? --AlexChurchill

Science


This is crying for a .wav :-)
SeeAlso the [flash animation] of TomLehrer's Elements song.
Planets of our Solar System: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. Ordered by mean distance from the Sun, which at present corresponds to the order of actual distance from the Sun. Predates Rupert.
I learned "Please, Sir, Can My Auntie Zena Iron Long Heavy Curtains (made of Silver and Gold)?" Presumably the italicised letters in the middles of the words are obscure metals my school didn't bother with. I'm guessing the L is lithium, but I can't work out the T. --Rachael
I think my school did the same as yours. The above is what I remember, but when I looked up the ReactivitySeries? I
found  lithium, tin and platinum included, which are not covered by the initials, so I thought I'd better highlight them. --Bobacus
Mine school used "Pink Sausages Certainly Make All Zebras In Lincoln Hospital Catch Salmonella" although I found it harder to remember the Mnemonic than the elements, especially since I generally thought of it as KNaCaMgAlZnFePbHCuAgAu? anyway --SF
Kazuhiko's suggestion for the most successful mnemonic of all time in that he still remembers it (and the associated fact) roughly 11 years after being taught it with no intervening need to actual remember.
ChrisHowlett can't figure out the fact assosciated with either of these last two.
I think the last one is biology (although not something we learned at my school, so that is a guess); I don't know the OBAFGKMQ one. --AC
Me neither - can someone explain it? --Rachael
The presence of two variants is consistent with it being an irrational mathematical constant, rounded to end in ...325 or ...32534. Unfortunately, I don't know of a constant that looks like 2.2144(3)42534 (x10^n) --CH
I guessed right on this one, but I had to google to check and get the details right. It's the classes of stars in the course of stellar evolution, from bright, hot stars to old cool ones. The RNS are classes that are no longer used - SunKitten
Kingdom, Phylum, Class, Order, (something, where's SunKitten when you need her?), Group, Species is the right order for classification, yes. --SF
'Family' is the word you want. Nice mnemonic :) - SunKitten, who's never been able to remember them
I learnt G as 'Genus' but I'm guessing the terms are probably interchangeable. --K
Actually, no, I don't think they are - well spotted - SunKitten
Eh? It was, until you added O and N --SF
Ah. Cunning. Mnemonic amended so it actually makes sense. --SF
Er...? Is StuartFraser arguing with himself here? Your honesty is commendable, but confusing... --AC
Yes, I am. This mnemonic (and the one below) is rather confusing because it uses chemical symbols rather than names, and chemical symbols can either be one or two letters. What makes it exceptionally confusing is that the last two refer to the Hydroxide and Nitrate (OH and NO3) anions, which aren't elements at all. The first time through I didn't realise this, hence my comment. I then realised what was going on and amended the Mnemonic for clarity. --SF
Again, this isn't very good. Cu, Fe and Co have multiple valencies, I've got no idea what "P" refers to, but it ain't Phosphorous, and two S's? One's sulphur, but what's the other? --SF
See above, the answer being "Sulphate". --SF
Public is Pb.  Which can also have a valency of four.  Companies is actually carbonate, CO3.  And it isn't very good as it was only GCSE science, so what do you expect? :P --Jumlian
