Title: Mnemonic Devices That Worked for You
Post by: wastrel on May 28, 2019, 02:00:12 PM
I was able to instantly recall the mnemonic devices I learned 20+ years ago yesterday for  the basic seven levels of taxonomy (Kings Play Chess On Fine Grain Sand). 

I can also easily recall a couple of math ones, such as:
Some Old Horse (Sine = Opposite/Hypotenuse)
Caught Another Horse (Cosine = Adjacent/Hypotenuse)
Taking Oats Away (Tangent = Opposite/Adjacent)

PEMDAS for order of operations

Any others instantly pop into your head years later?

DDSSHGB  or "DD-destroyer" "SS-submarine" and "HGB-heavy gun boat."*

From that I get
Doc
Dopey
Sneezy
Sleepy
Happy
Grumpy
and
Bashful.

Very important, that one. ;D

I also use "Chose-Hose" to avoid the "Chose-Choose" typo.

*That last one isn't strictly a USN designation, btw.

My mnemonic for remembering the order of the planets:

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.

The last because I learned it prior to 2006.

To remember which direction to move the clocks for Daylight savings (Start and Finish): Spring Forward, Fall Back

Stalactites cling tight to the ceiling. Stalagmites might grow up to meet them.

To remember the difference between Port and Starboard. Port and Left both have 4 letters

For First Aid response. DRS. ABCD (Doctors ABCD) Danger, Response, Send for Help, Airway, Breathing, Circulation, Defibrillation[/b]

Or is it Spring Back, Fall Forward? I can never remember which.

Stalactites cling tight to the ceiling. Stalagmites might grow up to meet them.

When the mites go up, the tites come down.

To remember the difference between Port and Starboard. Port and Left both have 4 letters

There's a little bit of port left in the bottle.

I don't need any of these, they are all instinctive now.  But I still remember.


If you put an 'a' in definitely, you're definitely an a-hole.

WE will remember our West from East.

As far as remembering directions.  The road we lived on went north-south, and so I never had a problem with north and south.

But east-west I would always have to think for a minute.  And the nonsensical way I would think about it was "well, Newfoundland is that way, so that way must be east".  It's also 5000 miles across the country, so why could I remember that Newfoundland it that way, but not that east is that way?

From the Muppet movie, "Hey I've never seen the sun come up in the West?!" is how I used to remember which way the earth rotates. That and, "Half an hour later in Newfoundland."

Here's what I could never understand (and it's similar to the fall forward spring back issue). When you're talking about rotation, which is right and which is left? Is right clockwise? Is left clockwise? It was never clear to me.

Left and right only apply from the 9 o'clock position to the 3 o'clock position

Left is anti-clockwise. Right is clockwise.

I find lefty loosy and righty tighty confusing, as half the time I am on the opposite side or upside down to the nut, fitting etc that I'm working on which makes the mnemonic backwards.
or, as stated above, working on gas fittings which are reverse thread on purpose.

See if someone had told me that, I wouldn't have been as confused!

The left side of bicycle pedals (and many other items, including gas fittings and mower blades and most older vehicle when lugs) it is lefty tighty.

One I have taught is FACETS,  probably the best way to not die in an avalanche.

The human factor. According to avalanche researcher Ian McCammon, the main human factors (heuristics) that may influence decisions are: Familiarity, Acceptance, Consistency, Experts, Tracks/Scarcity and Social Facilitation.These factors form the acronym FACETS.

Might be a concept applicable to other situations as well.

Oh, facets describe a metamorphic snow crystal that can produce weak layers in the snow pack and are a significant factor in avalanches.

For remembering the OSI model:

From top-down order: "All people seem to need data processing."

Or from low-to-high order: "Please do not throw sausage pizza away."

I tend to avoid mnemonics as it's as easy to get them wrong as it is to get them right. But I do remember the difference between" principle" and "principal", as I once attended a school where the principal told us that the princiPAL is your PAL.  The mere thought of that man being mine or anyone else's pal was so ludicrous and horrifying a thought that I still remember it now.

In general, I am opposed to teaching mnemonics, but a few that I've used for myself are:

Oh Be A Fine Girl, Kiss Me (spectral classes for stars). Obviously a bit problematic in a modern context.

King Philip Came Over From Great Spain (taxonomy)

Right hand rule for cross products

Circle diagram from quaternion multiplication

For the planets: My very educated mother just served us nine pickles. (Obviously before the demotion of Pluto.)

To spell the word arithmetic: A red Indian thought he might eat tomatoes in church.

I never needed a mnemonic for starboard and port. Oddly, I have to think about which side is right and which is left more than I have to think about which is starboard and which is larboard (port).

The only word I still remember from high school French is finetra (window) because I had such a hard time with it that I invented: An infinite number of extra fans by the window.

I always used "spring forward, fall back" but now I can forget that one because Hawaii very sensibly does not have daylight saving time. Hawaiian names, however, do not lend themselves well to English language Mnemonics.

You don't need it in the tropics. The variation in day lengths isn't as great as places further from the equator.
