Listing the hits

Some fortunate coincidences make the TM system convenient to use, over and above what was intentionally arranged for. These accidental hits keep mounting up—I ecently came across several more. Here's an updated list as of February 2003.

• Since the earth's average orbit speed is about one tenthousandth of c, it turns out to be 1000 miles a minute.
• In much of the earth's atmosphere (a deep layer above convection, with roughly constant temperature) sound goes 10 miles a minute, though 11 is typical for room temperature air.
• The earth's average density is slightly over one talent per gallon.
• At human body temp and standard sealevel air pressure the molar volume is one gallon. A gallon-sized lungful of air contains E23 air molecules.
• A cubic mile of space near the earth contains E23 photons of sunlight---a mole of sunlight.
• The talent-mile charge unit is a mole of electrons.
• The talent-mile eevee is E-23 ocmile. That is, the standard energy unit is a mole of electron volts.
• The talent-mile power unit---ocmile per minute---is close to half a horsepower and is called pony. In metric terms a pony of power is about 360 watts. The intensity of sunlight at this distance from the sun is E7 ponies per sqmile.
• The sun's power output is E24 ponies.
• The average energy of a quantum of sunlight is E-23 ocmile. A cubic mile of sunlight at this distance from the sun contains one talent-mile unit (one ocmile) of energy. That is, sunlight has the *unit energy density* in these units.
• The most important energy density in the universe, for its longterm development and eventual fate, is one tenthousandth of this. Dark energy density is one tenthousandth of an ocmile per cubicmile.
• An ocmile is about 5 food Calories.
