So, can you name the Seven Wonders of the Ancient World? As the list was compiled in Greece, it only includes structures located around the Mediterranean rim. They did not all exist concurrently, and only one remains in existence today.  Although there were actually a number of such lists, the list that is known today is believed to have been finalized around the fifth century A.D.

Pyramid of Giza – The only Wonder still in existence.  The largest and oldest of three pyramids, the Great Pyramid was built by the Egyptians in the 26th century B.C. for Pharaoh Khufu (Cheops).  Its height was more than 480 feet, and it was constructed from about 2.3 million blocks of stone, averaging 2.5 tons in weight.  Each side is oriented to one of the cardinal points of the compass, and it is filled with a number of corridors, shafts, galleries and chambers. The outside was once encased in fine white limestone.  It was the tallest structure on Earth for almost 4000 years.

Hanging Gardens of Babylon – Although there is some dispute as to whether, or where, these gardens actually existed, they are believed to have been built by Babylonian King Nebuchadnezzar II around 600 B.C. for his homesick Queen.  The gardens would have grown from a series of vaulted terraces within his palace grounds, and would have likely been “overhanging” rather than “hanging”.  They are believed to have been irrigated by water pumped up from the Euphrates, and they are thought to have been destroyed by earthquake.

Temple of Artemis at Ephesus – The shrine was destroyed and rebuilt many times, but the Anatolian temple erected around 550 B.C. by Theodorus was considered very impressive.  It was 300 feet in length and 150 feet wide, with more than 100 columns supporting the enormous roof.  In 356 B.C. it was destroyed by arson and rebuilt once again by Scopas of Paros as the first building to be made completely of marble, and stood 425 feet in length and 225 feet in width, with 127 of its 60-foot columns supporting the roof.  Thirty-six of these columns featured figures carved in high relief on their lower portions.  This temple was destroyed during a raid by the Goths in 262 A.D.

Statue of Zeus at Olympia – The Olympics were started in 776 B.C., held on the site of Olympia in Greece, which contained a stadium and a sacred grove where the temples were located.  The centerpiece of its shrine to Zeus was a 40 foot tall statue of Zeus, completed by Phidias in 435 B.C., and covered in gold and ivory plates.  The statue was seated on a throne covered in gold, ebony and ivory, and inlaid with precious stones. In 392 A.D. the games were abolished, and the statue moved to Constantinople, where in was destroyed in a fire in 462 A.D.

Mausoleum of Halicarnassus – Constructed in 356 B.C. by Scopas of Paros and other world-famous sculptors of the day as an elaborate tomb for King Mausolus, a Hellenized Carian, the mausoleum was 135 feet tall.  It had a pyramidal roof, topped by a massive sculpture of four horses pulling a chariot, and sat in an enclosed courtyard filled with statuary.  It was made of bricks covered in white marble, and was covered with relief sculpture.  It survived until an earthquake in medieval times.

Colossus of Rhodes – After successfully resisting a year-long siege resulting from the break-up of Alexander’s empire upon his death, Rhodes’ Hellenistic army melted down its bronze and iron weapons and sold the other war equipment to erect a 110 foot statue of the sun god Helios.  Completed in 280 B.C. by Chares of Lindos, it stood on a 50-foot marble pedestal by the harbor.  It was constructed of bronze plates over an iron framework, with several stone columns inside the statue acting as support.  An earthquake brought it down 56 years later.

Lighthouse of Alexandria – On the small Hellenistic island of Pharos, in Alexandria’s harbor, stood the original lighthouse at around 450 feet in height, although some scholars believe it was even higher.  It was erected in 270 B.C. by Sostrates of Knidos, and constructed of marble blocks with lead mortar, in 3 distinct sections   At the top, bronze mirrors reflected the sunlight during the day, and fire at night.  An earthquake brought it down in the 14th century, making the lighthouse the last of the six wonders no longer in existence to disappear.

Here’s a helpful map of these Wonders to put them in some context: Map at WorldAtlas.com.

Slacker Personal Radio

Slacker Personal Radio

If you love music, any kind of music, then you should check out Slacker. Slacker Personal Radio is free personalized radio with millions of songs from thousands of artists from around the world. For a few dollars a month, you can even lose the few ads, have complete song lyrics and unlimited skips, and their Slacker G2 portable mini player.

The site is very easy to navigate, and is organized into stations. There is a wide range of preprogrammed stations to choose from, including a Slacker’s Spotlight Station and the Top Stations that others are listening to, or you can program your own custom station. While you are listening to a station, you can explore a clickable playlist for the station, and a clickable listing of the artists included on the station, and related artists. It’s so easy to go off clicking and exploring, and end up listening to something completely amazing and unexpected. While the music is playing, you can view a biography of the artist, the album’s cover art, and song lyrics. Slacker also remembers what you have recently played.

There are many active forums, where users can share musical discoveries or their custom stations with each other, or chat about the various preprogrammed stations. Requests can be made here for additional new artists or stations to be included.

And, you can take it everywhere with Slacker’s mobile application, either on your Blackberry Smartphone, IPhone or IPod, or the Slacker G2 device. CNet called Slacker Personal Radio “Best. Streaming music app. Ever.”

I  listened to Bluegrass music and Comedy, discovered the incredible John Lee Hooker and Cristina Branco, and remembered how much I liked Christina Aguilera and Antonin Dvorak.

A word of warning though: it’s too easy to spend hours looking through all of the great music, finding new favorites.  Also, it’s not really designed to listen to song after song by the same artist, but to listen to different artists across a musical genre, much like what you would hear listening to a traditional radio station.  I often keep it playing in the background while I work on something else.

Charity Navigator

I think that many of us would be glad to aid someone less fortunate than ourselves, or contribute to a cause that we care about, given the right circumstances. If we are financially able to help at the time, if we find something to contribute to that we believe in and that moves us to become involved, and if we are confident that our donation will actually reach who or what we are trying to better, then the choice to help is ours to make. If and when each of us gives is a personal matter, but it is possible to easily learn a great deal about which charity to choose, in order to make the best informed decision, and ensure that the greatest percentage of your donation reaches its intended recipient.

There are several independent national charity evaluation sites available to make this decision easier, Charity Navigator being the largest, best known and most comprehensive. Over 5400 of America’s largest charities are reviewed there, and the site is very easy to navigate (no pun intended). It only evaluates tax-exempt organizations, and does not review lobbying groups, religious organizations, private foundations, charities based outside the U.S., hospitals, universities, community foundations, PBS stations, charities newer than 4 years old, or those that receive less than $500,000 in public support. If you are looking to give within these parameters, then you can find a wealth of information to help make your decision.

Charities are rated based upon their organizational efficiency and capacity. Information from income statements, donor privacy policies, mission statements, and CEO compensation reporting is also included, as is a link to the charity’s own site. Charts featuring the percentage of donations that reach the charity’s beneficiaries figure prominently. Links to the rating pages of other charities doing similar types of work are also given. Charities can be browsed through by category, and the data resulting from the reviews is used to create many interesting top ten lists, highlighting such subjects as highly rated charities with low CEO pay, and those of the reverse, those in financial trouble, those stockpiling donation revenue, those most commented upon, and more. If you become a free registered user, you can also view historical data, comment on a charity, and save search results.

At the end of your research, you can actually contribute to the charity of your choice through Network for Good’s secure giving service, if you wish. Charity Navigator is a valuable resource that can help make the decision of which charity to give to an easy, informed and secure one.

Science News

How should the term “intelligence” be defined in scientific research?  Would an accurate definition include a capacity for learning, reasoning or problem-solving?  What of a definition for the term “behavior’?  Would such a definition simply be observable activity in response to stimuli?  There’s an interesting article in the current Science News Magazine that explains how botanists on the cutting edge of research are now struggling with these questions.  The current distinction between the study of animals and plants results in two differing means of research, each with its own unique methods and perspectives.  Could borrowing some of the language and techniques of animal researchers be appropriate in research done by plant scientists, and benefit future understanding in plant research?  After all, much of plants’ activity (behavior?), carried out via chemical secretions, would sound very familiar to an animal behaviorist.  And the key neurotransmitters occuring in animals are also present in plants.

Of course, plants can be said to hunt, in a sense, simply by sending roots out, as they strategically focus on root growth in more rich soil, to the detriment of other root growth in poorer soil.  If a plant is in a medium that does not contain sufficient levels of phosphorus, they do chemically cause the pH of the surrounding medium to drop in order to increase their phosphorus intake.  Neighboring plants will also struggle over limited resources.

If a plant is attacked, it releases a highly-specialized mixture of chemicals.  With some plants, this mixture even differs depending upon the nature of the attacker.  These chemicals serve to specifically attract those insects that eat other insects, and they respond by approaching and eating the insect that is attacking the plant.  These chemicals are quite detailed, as it has been found that any of these insect-eating insects will only respond to those chemical messages sent out regarding the insect prey that they prefer to eat, while they will ignore other chemical messages.  It has also been shown that neighboring leaves and plants that have sensed these airborne chemical messages respond more quickly to an attack on them than they would have otherwise.  Could this not be defined as communication?

Also, plants that have been through this scenario once have been shown to respond more quickly to a subsequent attack.  Would this reaction constitute evidence of some rudimentary form of memory?

There is even evidence that plants have some ability to be aware of self.  Plant leaves will react differently to airborne chemical signals from other leaves on the same plant than they will to airborne chemical signals from different plants.

Perhaps the rigid boundary between plant and animal study is ultimately unnecessary, only serving to hinder a better understanding of each, and only a (to use a rather tired but accurate term) more holistic mindset is what would best gain a more complete understanding of them both.  It is somehow reminiscent of the struggle to discover a unified field theory in physics.  Perhaps scientists can begin to find more of their answers with a simple change in perspective?

Suzani

Suzani

A suzani is a beautiful decorative textile, embroidered with silk thread, that originates in Central Asia, generally in Uzbekistan and Tajikistan along the fabled Silk Road.  The term suzani comes from suzan, the Persian word for needle.  Traditionally, a family began creating suzani at the birth of a daughter, and she continued the work until it became her dowry.  They were created by several women in the family embroidering separate panels, which were then joined together.

As many different peoples have lived scattered throughout Central Asia, different regions developed their own distinct colors and patterns and motifs.  Additionally, each tribe within these groups also had their own crests that they included within their textiles.  The trade along the Silk Road also greatly influenced their designs, as patterns and motifs from India, China and Persia, as well as Hellenic influences from the West, traveled up and down the trade routes.

Suzani are commonly thought of as being divided into Eastern and Western categories, based upon color and design, with the Eastern group closer to the traditional bold designs of the nomadic Uzbeks and Kyrgyz,

while the Western group is often characterized by flower and vegetation motifs, and influences from India and Kashmir.

The beauty and artistry of these textiles is just amazing, and the skill and creativity needed to create these works of art is quite impressive.  A quick search on the term suzani will turn up many beautiful examples to enjoy viewing.

PostSecret Books

Have you found the site PostSecret yet?  The premise of the site is quite interesting, and the outcome is remarkable.  PostSecret describes itself as “an ongoing community art project where people mail in their secrets anonymously on one side of a postcard”.  The resulting collection is both moving and humorous, and it includes messages that are by turns filled with anguish and wisdom, hilarity and pathos.

Scrolling through the site, there is a certain feeling of looking through someone else’s diary, but this somehow doesn’t leave one feeling dirty, perhaps because it is clear how empowering such an experience was for the authors.  The postcards themselves are very often quite creative and artistic in and of themselves.

There are several books compiled from submissions not seen on the site, and there are even traveling exhibitions seen in museums and galleries around the country.  Readers of the site are also able to comment on individual entries, and there is a community chat forum that the compiler visits.

Visiting the site left me considering what secret I would share, and what that secret would say about who I am.

So, I knew that I wanted to change my theme, but I was dreading the almost inevitable I’m-in-way-over-my-head-here outcome.  I’m usually pretty good at figuring things out on my own, but how far was a fairly decent working knowledge of HTML going to get me?  As it turned out, I had nothing to worry about, as the whole process went quickly and easily, thanks in large part to the creators of my new theme, Template Lite.

First I needed to chose my new theme, which of course takes forever.  They all start to look same after a while, don’t they?  And everyone around you quickly tires of, “So, what do you think of this one?”  Finally, I found one that I liked, that could do what I wanted, and didn’t appear ready to bring great buggy disaster down upon my blog.

I needed to install a new plug-in first, flickrRSS, for the Flickr photostream at the bottom of the page, and that was simple enough.  Download, activate the plug-in, and configure the settings.  Then I just copied a bit of code onto my footer template, and it was done.  Very nice, thank you to Dave Kellam and Stefano Verna for the cool plug-in.

Then I was ready to hit the download theme button, as I mumbled a little prayer to the technology gods to please be kind.  I received a folder that I uploaded into my blog directory (in wp-content/themes).  My only confusion came when it took me several minutes to figure out that I couldn’t upload the entire folder at once, but needed to create empty like-named folders in my blog directory first, then upload just the files into their appropriate new folders.  Feel free to chuckle if this seems obvious to you, but it threw me at first.  At any rate, it was then smooth sailing, as I just chose the new theme that appeared as a choice, and Presto!

Well, anyway, I hope that you like the new theme as much as I do.  I’ve heard some truly frightening theme-changing stories, but my experience was great.  Template Lite has a number of nice free themes that don’t just look like everyone else’s, so if you’re looking, they’re a good resource to check out.  I’d definitely give them a good review.
