From Cambridge to Eternity: “Dimension Algebra 03”

 

<Problems and Applications>

         *Note: “T” for time period, “L” for length, “M” for mass and “U” for value of utility

                         There are indefinitely many scales per T, L, L2, L3, M or U.                


1.     The time taken in the 100m dash: T= L/ (LT-1)

- El Condor: 8 milli-sec= 100m/ (12.5m/ milli-sec)

- The winner: 8 sec= 100m/ (12.5m/ sec)

- The laggard: 8 min= 100m/ 12.5m/ min)

- The Snail: 8 hours= 100m (12.5m/ hour)

*Notwithstanding the Solow model, no “marathoner” has ever won in a public event of 100m dash.    


2.     The travel distance of the sunlight: L= T(LT-1)

- In two seconds: 600,000 km= 2 sec(300,000 km/ sec)

- In 100 years: 100 light-years= 100 years ∙(1 light-year/ year)


3.     The private “constant” k (= M/ I) as in the Cambridge equation: T= Um/ (UmT-1)

 (More on this tomorrow)

- The daily bread earner (id): k= (0.5id in average) / (360 id per annum)= 0.001 year  

- The wage-earner (i2w): k= (0.5/27)= 0.02 year

- The “salary-person” of “Tokyo style (im): k=(0.5 /12)= 0.04 year

- The fund manager of “Manhattan style” (iy): k=(0.5/ 1) = 0.5 year

- An Elon Musk (indefinitely large sum at any moment): (definitely unnamable) year

- The central banker: “Begin this Printing Press Now!” year


4.     The percentage rate of economic growth: (100T-1 ) %

- “Finlandia”: 5 % per annum, or (5/ 360) % per diem

- “Failed Nation”: -3 % per annum, or -(3/ 360) % per diem 

- “The Isle of the Dead”: -123 %, +(3.14159x 10456) % or any % of convenience


5.     The purchasing force of money: MU

- The dollar (Um): the utility (MU) worth a dollar

- The euro: the utility worth a euro               

- The thaler: the utility worth a thaler


6.     The speed of time: Flying (= LT-1) vs. Lapsing (= TT-1)

- Flying across space: 300,000 km/ sec

- Lapsing over time: 1= 1 hour/ hour = 1 year/ year

 Oh, time lapses precisely at the speed of time!
