Current Entry: Universal Measurement System
Universal measurement is a system of units based on constants thought to be appropriate for use throughout the universe. Jeff Rand put together this system, and at his suggestion, the system presented below was first adopted for Winter Camp use at Winter Camp II in 1978-indeed, the master copy of the schedule for that encampment is fully demarcated in jiffys without conversion factors. The system at Winter Camp II included units for distance, mass, time, and temperature. In 1994, further work was undertaken at the Winter Camp Bureau of Standards with the intent of defining absolute standards and base units for three additional quantities, thus developing a complete measurement system. While the system has not been in the forefront of Winter Camp measurement since then, it remains an important part of Winter Camp lore.
Universal Measurement: Fundamental Units
- Distance
- 1 tit (t) = The classical radius of an electron at rest. (Also known as the tic, a name assigned by Mark Bollman? on a number of occasions when he has taught about this system to various mathematics and physics classes beginning in 1993.)
- 1 tad (T) = 1015 tits.
- Mass
- 1 dash (d) = The mass of an electron at rest.
- 1 holbrook (hbk) = 1030 dashes.
- Time
- 1 flash (f) = Time taken for light to travel the classical radius of an electron in a vacuum.
- 1 jiffy (J) = 1026 flashes.
- 1 bluemoon (bm) = 1030 flashes.
- 1 hellfreeze (hf) = 1035 flashes.
- Temperature
- 1 scorch (s) = 10?1· Triple point of hydrogen (100% 1H isotopes)
- Electricity
- -1 zap (z) = The charge on an electron. This quantity is chosen so that an electron has charge of -1 zap and a proton has charge +1 zap.
- Amount of Substance
- 1 jimpop (jp) = The number of elementary objects equal to the number of atoms in .1 hbk of hydrogen-1.
- Luminous Intensity
- 1 gary (g) = The luminous intensity generated from the photon emitted by an electron jumping from the first excited state to the ground state in a hydrogen atom.
- Supplemental unit: Volume
While the official unit of volume in this system is the cubic tit, universal measurement follows the example set by the metric system (with the liter) in choosing a slightly more convenient unit for commonplace measurements. The stonesink was added to the system in 1997.- 1 stonesink (S) = 1 cubic decitad (1/1000 T3, 1 * 1042> t3)<.i>
