****The Official Friday Silliness Thread****

February 29th eh?

 

Why do we have Leap Day?

Observatory: Our solar year (the time required for Earth to travel once around the Sun) is 365.24219 days.

Our calendar year is either 365 days in non leap years or 366 days in leap years (Feb 29th inserted).

A leap year every 4 years gives us 365.25 days, sending our seasons off course and eventually in the wrong months.

To change .25 days to .24219, we need to skip a few leap days (Feb 29ths) .... century marks not divisible by 400. So with a few calculations tweek the calendar by skipping 3 of 4 century leap years to average out our calendar year to 365.2425, which is pretty darn close to the solar year 365.24219.

Here’s the history:
The Romans originally had a 355-day calendar. To keep up with the seasons, an extra 22 or 23-day month was inserted every second year. For reasons unknown, this extra month was only observed now and then. By Julius Caesar’s time, the seasons no longer occurred at the same calendar periods as history had shown. To correct this, Caesar eliminated the extra month and added one or two extra days to the end of various months (his month included, which was Quintilis, later renamed Julius we know it as July). This extended the calendar to 365 days. Also intended was an extra calendar day every fourth year (following the 28th day of Februarius). However, after Caesar’s death in 44 B.C., the calendars were written with an extra day every 3 years instead of every 4 until corrected in 8 A.D. So again, the calendar drifted away from the seasons. By 1582, Pope Gregory XIII recognized that Easter would eventually become closer and closer to Christmas. The calendar was reformed so that a leap day would occur in any year that is divisible by 4 but not divisible by 100 except when the year is divisible by 400. Thus 1600 and 2000, although century marks, have a Leap Day.

The calendar we use today, known as the Gregorian calendar, makes our year 365.2425 days only off from our solar year by .00031, which amounts to only one day’s error after 4,000 years.

You're a rather normal person, except that you have extraordinary luck in life.
People want to be around you (even when they're a little sick of you), in hopes of being lucky too!

Not sure if this has been posted today or even before, but thought it was funny so here it is.

For those who slept through World History 101..... here is a condensed version.

Humans originally existed as members of small bands of nomadic hunters/gatherers. They lived on deer in the mountains during the summer and would go to the coast and live on fish and lobster in the winter.

The two most important events in all of history were:
1. The invention of beer, and
2. The invention of the wheel. The wheel was invented to get man to the beer, and the beer to the man.

These facts formed the foundation of modern civilization and together were the catalyst for the splitting of humanity into two distinct subgroups:
1. Liberals
2. Conservatives.

Once beer was discovered, it required grain and that was the beginning of agriculture. Neither the glass bottle nor aluminum can were invented yet, so while our early humans were sitting around waiting for them to be invented, they just stayed close to the brewery. That’s how villages were formed.

Some men spent their days tracking and killing animals to BBQ at night while they were drinking beer. This was the beginning of what is known as the Conservative movement.

Other men who were weaker and less skilled at hunting learned to live off the conservatives by showing up for the nightly BBQ’s and doing the sewing, fetching, and hair dressing. This was the beginning of the Liberal movement. Some of these liberal men eventually evolved into women. The rest became known as girlie-men.

Some noteworthy liberal achievements include the domestication of cats, the invention of group therapy and group hugs, the evolution of the Hollywood actor, and the concept of Democratic voting to decide how to divide all the meat and beer that conservatives provided.

Over the years, Conservatives came to be symbolized by the largest, most powerful land animal on earth, the elephant. Liberals are symbolized by the jackass.

Modern liberals like imported beer (with lime added), but most prefer white wine or imported bottled water. They eat raw fish but like their beef well done. Sushi, tofu, and French food are standard liberal fare. Another interesting evolutionary side note: most of liberal women have higher testosterone levels than their men.

Most social workers, personal injury attorneys, journalists, dreamers in Hollywood and group therapists are liberals. Liberals invented the designated hitter rule because it wasn’t fair to make the pitcher also bat.

Conservatives drink domestic beer. They eat red meat and still provide for their women. Conservatives are big-game hunters, rodeo cowboys, lumberjacks, construction workers, firemen, medical doctors, police officers, corporate executives, athletes, Marines, and generally anyone who works productively.

Conservatives who own companies hire other conservatives who want to work for a living.

Liberals produce little or nothing. They like to govern the producers and decide what to do with the production. Liberals believe Europeans are more enlightened than Americans. That is why most of the liberals remained in Europe when conservatives were coming to America. They crept in after the Wild West was tamed and created a business of trying to get more for nothing.

Here ends today’s lesson in world history.......
