h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

These cannont be left out! All of us in the States had to learn them as kids in grade school:

ROY G. BIV = Red, Orange, Yellow, Green, Blue, Indigo, and Violet, the colors in the light spectrum.

My Very Educated Mother Just Served Us Nine Pizzas = Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto, the order of the planets from closest to the sun to farthest from the sun.

Please Excuse My Dear Aunt Sally = Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction, the order of operations in mathmatics.

If I think of any more, I'll let you guys know!

My maths teacher made this up to help us remember how to work out Sine, Cosine and Tangent in triangles. Look at that, I remember the memory aid 16 years later. I've fogotten the spellings though. I also can't remember if they are divided by or multiplied by.

Sin = opposite/hypotenuse
Cosin = Adjacent/hypotenuse
Tangent = Opposite/adjacent

Easier to remember than SOHCAHTOA that my previous teacher tried on us!

On a musical note, and again I can remember the mnemonic but not the correct terms...
Notes on the spaces spelt face, and the ones on the () lines was
Every Good Boy Deserves Favours. Hopefully I've remembered that correctly.

Btw, it's Richard of York Gave Battle In Vain, although I don't know if he did or not. I learnt that one many years after I'd heard of the scientist Roy g. Biv as mentioned above.

Those music notes are for the treble clef only!

Bass clef went as follows:

Spaces= All Cows Eat Grass or All Cars Eat Gas

Lines = Good Boys Do Fine Always

Another way to remember the lines on the treble clef was Empty Garbage Before Dad Flips!

Thanks for adding that Lucreica, I knew my knowledge was very holey there.

Sin/Cos/Tan etc - we learnt using:
Silly Old Harry
Caught A Herring
Trawling Off America

How to remember what order one writes the sharps down in on when writing the key signature on a piece of music:

Fried Chicken Goes Down Awfully Easy Baby

And for the flats:

Big Elephants Always Drive Grey Cars Fast (or the reverse of "Fried Chicken")
