Archives For Sun is approximately 400 times the size of the Moon

This is POST #400!
This is POST #400!

I just figured out that this is my 400th post. I began writing on 7/3/2011, a little over four years ago. I have discovered that writing for this blog has given me the opportunity to research many topics and to explore what I think about those topics as I write.

In other words, I have increased my own background knowledge through reading and writing on this blog.

So, what could be the best way to celebrate this 400th post?

I can demonstrate how a post can increase a reader’s background knowledge on a topic as simple as the number 400!

There are multiple topics in various disciplines related to the number 400.  Here are several examples of what I learned by basing this post on the  significance of the number 400:

 

HISTORY
If this post were in Athens in 413 BCE, it could represent the The Four Hundred , a group that organized a revolution during the Peloponnesian War between Athens and Sparta. Their coup was organized after a financial crisis caused by a series of unsuccessful military campaigns, made them seek to establish an oligarchy of the elite. These Four Hundred were the wealthy members of the ruling class, and they believed that the oligarchy would manage foreign, fiscal, and war policies better than the more democratic government in place. (source: Wikipedia)

If this post was part of a  Gregorian calendar year calculator, it would show the changes according to one cycle of exactly 400 years, of which 97 are leap years and 303 are common. (source: Wikipedia)

COMPUTER CODING
If this post was a message from the Internet, it would be part of an HTTP status code for a bad client request. Receiving the message 400 means that the request was malformed. In other words, the data stream sent by the client to the server did not follow the rules. (source: Wikipedia)

ECONOMICS
If this post was in Forbes Magazine, it would be a listing of the 400 wealthiest people in the world. The methodology for gathering this information is from interviews with employees, handlers, rivals, peers and attorneys. Debt is also consider a factor. Other methods explained by Kerry A. Dolan from the Forbes Magazine staff in her article Inside The 2014 Forbes 400: Facts And Figures About America’s Wealthiest:

“We pored over thousands of SEC documents, court records, probate records, federal financial disclosures, and Web and print stories. We took into account all types of assets: stakes in public and private companies, real estate, art, yachts, planes, ranches, vineyards, jewelry, car collections and more.”

SOCIOLOGY
If this post was a socialite calculator for the mid-19th century, it would hold the number 400 as an elite standard based on a remark by from Manhattan’s most famous social arbiter, Ward McAllister. His remark “There are only 400 people in New York that one really knows,” was the basis for social reports chronicled in the New York Sun. According to Collins Dictionary Online,  The notion ‘elite’ is said to be from the selection of high society guests by the socialite Mrs. William B. Astor Jr., whose ballroom could hold 400.

TRANSPORTATION:
If this post was a passenger train, it would have the nickname “The 400″ because of the distance it traveled (400 miles) between Minneapolis/St. Paul and Chicago, Illinois in 400 minutes. (source: Wikipedia)

If this post was a highway, it would be part of the interstate system in Ontario, Canada, or part of the 400-Series Highways. These highways have high design standards,are regulated at 100 kilometres per hour (60 mph) speed limits, with various collision avoidance and traffic management systems. (source: Wikipedia)

 If this post was a boat yard, it would be the historic boat yard #400 in Belfast, Ireland, where the RMS Olympic was constructed, the first of the three Olympic-class ocean liners. The RMS Olympic was the RMS Titanic‘s sister ship. (source: Wikipedia)

SCIENCE
If this post was an explanation of the appearance of celestial objects, it would explain that while the Sun is approximately 400 times the size of the Moon, it is also approximately 400 times further away. Their astronomical size difference is not comparable because of a temporary illusion causing the Sun and Moon to appear as similar size in the Earth’s sky.

If this post was a tree, it would be one of 400 in the ratio of the number of trees per human on Earth today.  A new study  explained in Science Tech Today (Los Angeles Times / NewsEdge) estimates the number of trees at somewhere around 3.04 trillion, or 400 trees for every person. The new study notes that this is a reduction in about half the number of trees that have been on Earth:

“‘The number of trees cut down is almost 3 trillion since the start of human civilization’ said Thomas Crowther, a postdoctoral fellow at the Yale School of Forestry & Environmental Studies who led the study. ‘That is an astronomical figure.'”

SPORTS:
If this post was a batting average, it would represent (2 hits out of 5 at-bats) which is a numerically significant annual batting average statistic in Major League Baseball. Batting .400 was last accomplished by Ted Williams of the Boston Red Sox in 1941. (source: Wikipedia)

LITERATURE :

"The 400 Blows" is seminal work of the French New Wave (1959) and directorial debut of 27-year old Francois Truffaut

If this post was a measurement of time between the writings of the Hebrew Bible and the Christian New Testament texts, this post would represent the Intertestamental period, or roughly four hundred years.

If this post was part of a Bible as Literature study analysis, then this post would be discussing the verses from Acts in the Revised Standard Version:

“God spoke to this effect, that his posterity would be aliens in a land belonging to others, who would enslave them and ill-treat them four hundred years.‘But I will judge the nation which they serve,’ said God, ‘and after that they shall come out and worship me in this place.’”(Acts 7:6-8 )

If you were looking for this post in the Dewey Decimal system, you would be looking in the 400s-language section. (source: Wikipedia)

MUSIC
If this post was the central idea for a song, it would be for the song 400 Years by Peter Tosh (on the album Catch a Fire, produced by Bob Marley). Tosh was one of the core members of the band The Wailers (1963–1974), after which he established himself as a successful solo artist and a promoter of Rastafari.  Tosh explained that, “My songs are a revolution, not smiling songs.” He was murdered in 1987 during a brutal home invasion.  (source: Wikipedia)

The opening lyrics to this song:

400 years (400 years, 400 years. Wo-o-o-o)
And it’s the same –
The same (wo-o-o-o) philosophy
I’ve said it’s four hundred years;
(400 years, 400 years. Wo-o-o-o, wo-o-o-o)
Look, how long (wo-o-o-o)
And the people they (wo-o-o-o) still can’t see.
Why do they fight against the poor youth of today?
And without these youths, they would be gone –
All gone astray….
So, in celebration of the 400th post, you could listen to the song:

 

All of the above evidence on the significance of the number 400 is proof that every time I sit and write a post, the research that I do for that post has increased my background knowledge.

I hope you learned something new to add to your background knowledge from this 400th post!
