The Bully Mnemonic

What is the Bully Mnemonic Device?

A mnemonic device (or memory device) is a technique for retaining information.

The Bully Mnemonic is a technique for remembering the exact number of seconds that occur in Earth's sidereal year, and the approximate relationship that exists between Earth's sidereal year, Earth's Great Year, and the Solar System's Galactic year.

The Bully Mnemonic Step 1

The first step is to write down the first five digits:

$${\begin{matrix}1&2&3&4&5\end{matrix}}$$

The Bully Mnemonic Step 2

The second step is to select odd digits:

$${\begin{matrix}{\color {Red}1}&\scriptstyle {\text{2}}&{\color {Red}3}&\scriptstyle {\text{4}}&{\color {Red}5}\end{matrix}}$$

The Bully Mnemonic Step 3

The third step is to intersperse the odd digits with zeros into the two integers shown below (important to remember that the first integer ends with an extra 0, but the second integer ends with 5):

$${\begin{matrix}{\color {Red}1}&\scriptstyle {\text{2}}&{\color {Red}3}&\scriptstyle {\text{4}}&{\color {Red}5}\end{matrix}}$$

$${\color {Red}1}0{\color {Red}33}0$$

$${\color {Red}3}0{\color {Red}55}$$

The Bully Mnemonic Step 2

Select the odd digits:

$$12345$$

$$({10330}\cdot {0.40})({\frac {10330}{0.40}})({10330}\cdot {3055})=(4132)\cdot (25825)\cdot (31558150)$$
