Viewed from space, the Earth appears to have four or five major landmass areas depending on your viewpoint. Despite this, we hold on to the illusion there are more continents.

As we all learned in grade school, there are seven continents. A quick look at a globe, however, reveals this basic assumption is just flat wrong. In particular, how can Europe be considered a continent when there is no clear division with Russia?

To the surprise of many, the Arctic is not classified as a continent. Instead, it is divided up between North America and Asia. Yes, Asia because Russia is considered to be part of it in the seven continents model. Following are the accepted seven continents in alphabetical order.

Africa is undeniably a continent by any definition. It is also the second largest one as a measure of landmass, covering over 11,700,000 square miles and making up 5.9 percent of the total surface of the Earth. As a measure of population, Africa is second most populous continent with over 840 million people.

Antarctica is also considered a continent, if a particularly barren one. 98 percent of Antarctica is covered in ice and it is the only continent neither considered a country nor claimed by any other country.

Based on sheer size, Asia is the dominant continent in the world. It has the largest landmass area and is home to over 60 percent of all humans. Talk about traffic jams! In truth, the measurements on Asia can be a bit misleading. Under the seven continents methodology, Asia extends over much of Russia, the Mideast and even parts of Egypt.

Often referred to as the forgotten continent, Australia is the fourth continent. Incorrectly referred to as an island for significant periods of history, Australia is undoubtedly a continent. That being said, it is the smallest in landmass with just more than 4,000,000 square miles, but has a healthy population of over 20 million people.

Europe is also considered a continent, but there is little geographic evidence supporting this claim. The continental designation is primarily a political and historical development. Regardless, Europe covers an area of 4 million square miles, but is heavily populated with over eleven percent of the world population at 705 million people.

North America is our next continent. Once again, we run into the practical issue of boundaries. Using the seven continent methodology, North America extends into the arctic as expected, but is also considered to include much of Central America. The total landmass is 9.45 million square miles. 514 million people are estimated to live in North America.

Our final continent is South America. Covering 6.9 million square miles, South America covers 3.5 percent of the total surface of the Earth. With a population of 371 million people, it ranks as the fifth most populous nation.

The misleading nature of the seven continent theory has to do with Europe. If the countries of Europe weren’t such powerful entities through history, would we really consider it a continent? Not likely!

The transmission of images obsessed inventors as early as 1875 when George Carey of Boston proposed his cumbersome system. Only five years later, the principle of scanning a picture, line by line and frame by frame – still used in modern television sets – was proposed simultaneously in the USA (by W.E. Sawyer) and in France (by Maurice Leblanc). The first complete television system – using the newly discovered properties of selenium – was patented in Germany in 1884, by Paul Nipkow. Boris Rosing of Russia actually transmitted images in 1907. The idea to incorporated cathode -ray tubes was proposed in 1911 by a Scottish engineer, Campbell Swinton.

Another Scot, John Logie Baird, beat American inventor C.F. Jenkins to the mark by giving the first public demonstration of – a dim and badly flickering – television in 1926 in Soho, London. Britain commenced experimental broadcasting almost immediately thereafter. Irish actress Peggy O’Neil was the first to be interviewed on TV in April 1930. The Japanese televised an elementary school baseball match in September 1931. Nazi Germany started its own broadcasting service in 1935 and offered coverage of the 1936 Olympics. By November 1936, the BBC was broadcasting daily from Alexandra Palace in London to all of 100 TV sets in the kingdom.

At the beginning there were many competing standards on both sides of the Atlantic. Baird’s technological solutions were trounced by Isaac Shoenberg and his team, set up in 1931 by Electric and Musical Industries (EMI). RCA refined its own system, as did the Dutch Philips. Not until 1951 were the standards for public broadcasting set in the USA and in Europe.

But the Americans were the ones to grasp the commercial implications of television. Bulova Clock paid $9 to WNBT of New York for the first 20-seconds TV spot, broadcast during a game between the Brooklyn Dodgers and the Philadelphia Phillies in July 1941. Soap operas followed in February 1947 (DuMont TV’s A Woman to Remember) and the first TV news helicopter was launched by KTLA Channel 5 in Los Angeles on 4 July 1958.

The first patent for color television was issued in Germany in 1904. Vladimir Kosma Zworykin, the Russia-born American innovator, came up with a complete color system in 1925. Baird himself demonstrated color TV transmission in 1928. Various researchers at Bell Laboratories perfected color television in the late 1920s. Georges Valenso of France patented a series of breakthrough technologies in 1938. But color TV became widespread only in the 1960s.

Orthodox Christians celebrate Christmas on January 7. Their “old new year” is a week later, on January 14. It is all Julius Caesar’s fault …

The Romans sometimes neglected to introduce an extra month every two years to amortize the difference between their lunar calendar and the natural solar year. Julius Caesar decreed that the year 46 BC should have 445 days (some historians implausibly say: 443 days) in order to bridge the yawning discrepancy that accumulated over the preceding seven centuries. It was aptly titled the “Year of Confusion”.

To “reset” the calendar, Julius Caesar affixed the New Year on January 1 (the day the Senate traditionally convened) and added a day or two to a few months.

He thus gave rise to the Julian Calendar, a latter day rendition of the Aristarchus calendar from 239 BC. After his assassination, the month of Quintilis was renamed Julius (July) in his honor.

The Julian calendar estimated the length of the natural solar year (the time it takes for the earth to make one orbit of the sun) to be 365 days and 6 hours. Every fourth year the extra six hours were collected and added as an extra day to the year, creating a leap year of 366 days.

But the calendar’s underlying estimate was off by 11 minutes and 14 seconds. It was longer than the natural solar year. The extra minutes accumulated to one whole day. By 325 AD, the Spring Equinox was arriving on March 21st on the Julian Calendar – instead of March 25.

The First Ecumenical Council met in Nicea in 325 and determined that the date to celebrate Pascha was on the first Sunday, after the first full moon, after the Spring Equinox on March 21st. In other words, it enshrined the Julian calendar’s aberration.

Thus, by 1582, the Spring Equinox was arriving on March 11. Half-hearted measures by Popes Paul III and Pius V failed to restore the essential correspondence between the calendar and the seasons.

Pope Gregory XIII decided – in his tenth year in office – to drop 3 leap years every 400 years by specifying that any year whose number ended with 00 must also be evenly divisible by 400 in order to have a 29-day February.

This would have the effect of bringing the Julian calendar closer to the natural length of the solar year – though an error of 26 seconds per year would still remain.

To calibrate the Julian calendar with the Gregorian one and to move the Spring Equinox back to March 21, 10 days were dropped from the civil calendar in October 1582. Thursday, October 4 was followed by Friday, October 15. People rioted in the streets throughout Europe, convinced that they have been robbed of 10 days.

But this was merely a convenient fiction. The Spring Equinox in the Gregorian calendar was, indeed, celebrated on March 21 in perpetuity. But, according to the Julian calendar, in the 17th century it arrived on March 11th, in the 18th century on March 10th, in the 19th century on March 9th, and in the 20th century on March 8th – 13 days earlier that even the erroneous date adopted by the Nicea Council.

The Gregorian calendar was controversial in Protestant countries. Britain and its colonies adopted it only in 1752. They had to drop 11 days from the civil calendar and move the official new year from March 25 to January 1. For centuries, dates followed by OS (“Old Style”) were according to the Julian calendar and dates followed by NS (“New Style”) according to the Gregorian one. Sweden adopted the Gregorian Calendar in 1753, Japan in 1873, Egypt in 1875, Eastern Europe between 1912 to 1919 and Turkey in 1927. In Russia it was decreed by the (bourgeois) revolutionaries that thirteen days would be omitted from the calendar, the day following January 31, 1918 becoming February 14, 1918.

It was Pope Pius X who, in 1910, changed the beginning of the ecclesiastical year from Christmas Day to January 1, effective from 1911 onwards.

All that time, the Christian Orthodox continued to observe the Julian calendar. In 1923, a Conference of Orthodox Churches in Constantinople reduced the number of leap years every 900 years and attained a discrepancy between the calendar and the natural solar year of merely 2.2 seconds per year.

According to this calendar, the Spring Equinox will regress by one day every 40,000 years.

They, too, had to drop 13 days to bring the Spring Equinox back to March 21st. Hence the gap between December 25 (Gregorian calendar) and January 7 (revised Julian-Orthodox calendar).
