Published estimates for the 1st century ("AD 1") suggest uncertainty of the order of 50% (estimates range between 150 and 330 million). Some estimates extend their timeline into deep prehistory, to " 10,000 BC", i.e., the early Holocene , when world population estimates range roughly between 1 and 10 million (with an uncertainty of up to an ...
As water hits the sink, it disperses, increasing in depth to a critical radius where the flow (supercritical with low depth, high velocity, and a Froude number greater than 1) must suddenly jump to a greater, subcritical depth (high depth, low velocity, and a Froude number less than 1) that is known to conserve momentum. Figure 2.
The known icy moons in this range are all ellipsoidal (except Proteus), but trans-Neptunian objects up to 450–500 km radius may be quite porous. [10] For simplicity and comparative purposes, the values are manually calculated assuming that the bodies are all spheres. The size of solid bodies does not include an object's atmosphere.

The 4-meter band (70–70.5 MHz) amateur radio allocation used in many European countries is entirely within the OIRT FM band. Operators on this band and the 6-meter band (50–54 MHz) use the presence of broadcast stations as an indication that there is an "opening" into Eastern Europe or Russia. This can be a mixed blessing because the 4 ...
The size of the Armenian American population is disputed, however. According to a 1988 news article, California had about 500,000 ethnic Armenians with over half of them living in Greater Los Angeles. [58] More than 1,300,000 Jewish Americans live in California, the majority of whom are Ashkenazi Jews. [59]
The usual size of the sensor is 18 mm × 13.5 mm (22.5 mm diagonal), with an imaging area of 17.3 mm × 13.0 mm, giving a diagonal of 21.64 mm. [17] [18] The sensor's area is about 30–40% smaller than APS-C sensors used in most other DSLRs, but still around 9 times larger than the 1/2.5" sensors typically used in compact digital cameras.
The population of England in 2021 was estimated to be 56,489,800. [4] [5] This is the most recent census. [4]In the previous census, in 2011, the population was 53,012,456. ...
