## Eponyms as mnemonics

10 AugDid you know that Melba toast was named after Dame Nellie Melba of that the word “nicotine” honors Jean Nicot de Villemain? These examples are from Alex Novak’s book *Tawdry Knickers and Other Unfortunate Ways to Be Remembered: A Saucy and Spirited History of Ninety Notorious Namesakes*

Eponyms can be powerful mnemonics and you can find a long list of them here.

## How to remember KIC 8462852

26 OctI am fascinated by the very remote possibility that observations of the star KIC 8462852 may be evidence for an extra-terrestrial civilization.

I don’t have the competence to evaluate or comment on the evidence. What I can do is help you to commit the name “KIC 8462852” to memory.

First, you need to know the Dominic System and the Peg System, they will take you only a few minutes to learn and its worth effort.

KIC stands for Kepler Input Catalog, but it might help to remember it as Kentucky Intergalactic Chicken (perhaps what they serve at the Star Wars bar).

Now, in the Domonic System 84 translates to HD – think Humpty Dumpty

62 is SB or Sleeping Beauty

85 is HE, why not Happy Easter?

Now we have one more digit 2 so lets use the Peg System and represent it as a shoe.

So just think of Humpty Dumpty, Sleeping Beauty, celebrating a happy Easter all nestled inside a shoe. The more ridiculous and vivid you can make the image the easier it will be to remember.

Now you’ll sound really smart.

## How to memorize a formula

18 SepYesterday, I blogged about a mnemonic for learning the quadratic equation. Here is an excellent video that teaches a general mnemonic technique for formula memorization:

## Quadratic formula mnemonic

17 SepGoing through some of my notes I rediscovered this mnemonic for the quadratic formula:

From square of b, take 4ac;

Square root extract, and b subtract;

Divide by 2a; you’ve x, hooray!

I am not sure of the origins of this mnemonic. The earliest version I could find was from J. S. Mackay in 1894, but he says the mnemonic was given to him by a member of the Edinburgh Mathematical Society.

Here’s another mnemonic for the quadratic formula:

And let’s not forget the Quadratic Formula Rap:
