the Pacific Ocean is officially the world's biggest ocean.

Lake Shrinkage Due
almost entirely to the extraction of water for irrigation purposes,
Aral Sea has shrunk the most in recent times having lost almost
two-thirds of its original size.
By 1994 (with 10,500 miles left
compared to 26,300 miles in 1950),
it had divided into two smaller
bodies of water.
Surface Area of the Earth:
196,935,000 Sq. Miles
Land Area on the Earth: 29.1%
Total Water Area: 70.9%
Type of Water: (97% salt), (3% fresh)
Circumference at the equator:
The earth orbits the Sun at: 66,700
mph per hour.
Fossil fuels supply over 80%
of the world’s energy needs .
All fossil fuels, whether solid,
liquid, or gas, are the result of
organic material being covered by successive
layers of sediment
over the course of millions of years.
Oil and natural gas were formed
from the slow
decomposition and burying of planktonic marine
and animals that sank to the muds of the sea floor.
...........Every year, the world burns through some thirty-eight billion barrels of oil,
six billion tons of coal, and a hundred trillion cubic feet of natural gas. The combustion
of these fossil fuels will produce, in aggregate, some four hundred quadrillion B.T.U.s
....of energy. It will also yield around thirty billion tons of carbon dioxide

nature of light, made in 1905,

speed of light
what does this sentence really mean???
the answer has nothing to do with the
actual speed of light, which is 186,000 miles per second

Instead, Einstein had an unexpected
that light from a moving source has the same velocity
from a stationary source.
For example, beams of light from a lighthouse,
from a speeding car's
headlights, and from the
lights on a supersonic jet all travel at a
