The war affected the growth of the federal government in three different major areas: public finance, military spending, and social welfare programs. Until World War II the individual income tax was a minor part of the federal government receipts (affecting no more than 3 percent of the population). However with the introduction of the employee withholding tax in 1943, for the first time a large percentage of the population was subject to the income tax.
Earth's axial tilt (obliquity) is currently about 23.4Â°. Earth's orbital plane is known as the ecliptic plane, and Earth's tilt is known to astronomers as the obliquity of the ecliptic, being the angle between the ecliptic and the celestial equator on the celestial sphere. It is denoted by the Greek letter Îµ. Earth currently has an axial tilt of about 23.4Â°.
If the earth's axis tilt had increased to 49 degrees, it should be possible to photograph vertical objects with no shadow in International Falls, Minnesota near June 21. And of course, you can't. The tropics are two parallels with latitude equal to the earth's axis tilt: 23.5 degrees. According to the axis-shift theory, the tilt is now 49.5 degrees, so the tropics are now at 49.5 north and south. Large cities with deep canyon streets would be a great place to test this theory. In New York, latitude 40.8 degrees, the sun should be directly overhead about May 18 and July 25.
