Favorite Mnemonics

The order of the planets:
My Very Educated Mother Just Sat On Nine Pizzas.

The colors of the rainbow: ROY G. BIV or Richard Of York Gave Battle In Vain

The order of biological taxonomic classification: King Phillip Came Over From Great Spain.

The order of electron orbitals: Sober Physicists Don’t Find Giraffes In the Kitchen

Trig rules: SOHCAHTOA (say it like “sockatowah!” and pretend it’s some ancient Indian word for triangle.)

Lines on the treble clef: Every Good Boy Deserves Fudge.

But my favorite of all, for remembering the order of the phases of cell division:

I Put My Ass Together.

The Great Lakes: HOMES (Huron, Ontario, Michigan, Erie, Superior)

The six counties of Northern Ireland: FAT DAD (Fermanagh, Armagh, Tyrone, Derry, Antrim, Down)

One I still remember from school, so it obviously worked:

Trigonomety: The cat sat on an orange and had hysterics, i.e.
T C S
O A O
A H H
so Cosine = Adjacent over Hypotenuse, for example

Oh, I missed your SOHCAHTOA. But I still prefer mine…

the order of sharps (on the music staff): Father Campbell got dinner at eleven bells.

the order of flats: Be a damn good c*** f***er.

Variations of two already mentioned

Planets: Mother Very Easily Made Jelly Sandwiches Under No Pressure

Great Lakes (in order from W to E): She Made Harry Eat Onions

There’s Righty tighty, Lefty loosie.

And from Scooby Doo of all places, how I remember the difference between cave formations: “Stalagmites hold tight, but stalactites might.” (Stalagmites hold tight to the cave floor-grow upwards- while stalactites might fall from the ceiling-grow downwards.)

The O should be a U for Uranus. I’ve known it as My Very Educated Mother Just Served Us Nine Pizzas

Spaces in the treble clef: FACE

And of course FOIL for Quadratics: First Outer Inner Last

Quiet Nerds Barf Only Near School.

According to Bart Simpson, those are the original Provinces of Canada (Quebec, New Brunswick, Ontario, Nova Scotia). Don’t know enough about Canadian history to verify it, though.

The order of planets

Mary’s Violet Eyes Made John Stay Up Nights Proposing.

The four points on a compass.

Never Eat Sour Watermelons.

Digits of Pi: Gee, I Wish I Could Calculate Pi Easily.

The number of letters in each word is a digit of pi. You can go a bit further, but the rest of the mnemonic isn’t very good. It’s something like: “Gee, I wish I could calculate Pi Easily, Homer did say, and if abominable snowmen…” and I forget the rest. It gets a bit strange - a friend and I had to make up a mnemonic to remember it in maths class when we were much younger and we rather gave up making it memorable after the first bit.

For the Color Code of resistors, it’s
Big Boys Race Our Young Girls But Violet Generally Wins

Apparently an older, politically incorrect version was

Bad Boys Rape Our Young Girls But Violet Gives Willingly

Crude and osbcene, but it performs its purpose – I remember it.
Then there’s the directional mnemonic:

Can Dead Men Vote Twice?
Which works backwards as

Timid Virgins Make Dull Company
In mnemonics, as in all else, sex sells.

My WTF? moment for the day…

I read this thread as “Favorite MENNONITES”

And these are NEW glasses!:smiley:

Value of “e” (base of the natural logarithm)

2.714921492459045

2.7 (you just have to remember this part)
1492 twice (Columbus’ first voyage to the Americas)
45 90 45 (angles of a 45-degree triangle)

Another “Columbus”

Once columbus is two horsepower, ie:
1492 watts = 2 HP

The first mnemonic I can remember is from elementry school, to help to spell “together”.

To - Get - Her

Even to this day, I can’t spell that word and not have this little tiny voice in the back of my brain whisper “to, get, her”.

Unless America was discovered in 1828 that first one is wrong

The version I grew up with is even less PC, and thus apparently even older:

Black Boys Rape Our Young Girls Behind Victory Garden Walls.

Crude yes, but it removes all doubt of which “B” is black and which is brown. Unfortunately, it doesn’t do anything to help with which is “G” is green or gray.

Thirty is hot,
Twenty is nice,
Ten is cool,
Zero is ice.
— how to read a Celsuis weather report when you’re used to Fahrenheit temperatures

I shake my head at all the mnemonics for remembering the planets, as I just remember the names as easily as any mnemonic.

Have seven extra digits on me: “How I Need A Drink, (Alcoholic, Of Course,) After The Heavy Lectures Of Quantum Mechanics.”

For the order of the planets, I’ve always relied on “Many Villians Earn Money Just Stealing Uncle’s Necktie Pins.”

(And in my favourite alternate universe, “Mother Very Easily Made JAM Sandwiches Using No Peanutbutter, Mayonnaise, or Glue.”)

For plant nutrients: “See Hopkin’s Cafe? Mighty Good!” (C, H, O, P, K, N, S, Ca, Fe, Mg)
Works best for growing fava beans, of course. :wink:

My favourites, though are the entirely personal ones.
I tend to remember phone numbers with completely idiomatic memnomic tricks, like “Lithuanian Lunar Jedi.”

Hey, that reminds me, I ought to call her today.

But there’s still plenty of room for confusion. All the “black” boys I know have Brown Behinds. (Sorry.)

You’re right, reviewing it in my head I say “1828” when on autopilot but my Mnemonic is “Columbus”. Now I got to find out what sea voyage took place in 1828 or if Columbus did something significant in that year.

Off to Google…

Well, sure, but when you were five or six, you probably needed a mnemonic.

And thanks to the Coach, from Cheers, I will always remember this about Albania
