1000 to 1300 AD can be written as: M - MCCC AD.
43 AD to 410 AD.
Longer periods were given in lifetimes or generations (saecula, aion), period, used by Al-Biruni around AD 1000, and by Roger Bacon in the 13th century.
Let us put reasonable bounds on the value of the world's population in AD 1. For the sake of example, I'll choose a lower bound of 50,000,000 (8 significant figures specified), and an upper bound of 200,000,000 (9 sig. figs. specified). Similarly, I'll put bounds on the population in AD 1000 at 250,000,000 and 350,000,000 (both exact). Note that the world's population must be an integer greater than or equal to 0; therefore, these values are exact -- there can be no loss of precision in the calculation due to these numbers. Using x = 2 (exact) and a generation length of (exactly) 40 years, we generate the following table : Population -------------------------------------------------- AD 1 | AD 1000 | C (rounded for convenience) -------------------------------------------------- 50 mil | 250 mil | 1.0665 200 mil | 250 mil | 1.00897 (min) 50 mil | 350 mil | 1.0809 (max) 200 mil | 350 mil | 1.02264 P(n) is a monotonically increasing function of c for the values of x and n chosen. Therefore, if the actual populations in AD 1 and AD 1000 lie within the given bounds, then c must lie within the interval [1.00897, 1.0809].
CPM for Print is easy. Ad Cost x 1000 / Circulation SO.....for a $3000 print ad....with a 90,000 copy print run $3000 x 1000 = 3,000,000 3,000,000 / 90,000 copies of the paper = $33.33 CPM FYI - CPM = Cost Per Mille (French for Thousand)
Around 1000 AD
Norsemen, also called Vikings, settled briefly at L'Anse aux Meadows in Newfoundland around 1000 AD.
The terrain, the amount of rainfall, and the quality of the soil affected the population density in Western Europe around 1000 AD.
yes.
Village
That was Lief Erikson
1000 to 1300 AD can be written as: M - MCCC AD.
Possibly Leif Ericsson
That was Lief Erikson
Peasant village
Leif Erikson was the first known non-native American explorer to land on North American soil around 1000 ad
He was part of the ancient Greek religion, which flouroshed from some 1000 AD till the advent of Christianity in the fourth century AD.
