Have you ever looked at a telephone pole and noticed those glass or porcelain pieces on top? They might look like just decorations, but they actually have an important job in communication. These helpful items are called insulators, and they help keep our electrical wires safe and our phone calls clear.
Safeguarding the Flow of Electricity
Insulators have a key job: they stop electrical wires from touching the pole or the ground. Imagine trying to make a long-distance call, and your voice suddenly cuts out after a little while. That wouldn’t be fun, right? Insulators make sure all the electricity stays in the wires so our important phone calls can keep going without any problems.
The Variety of Insulators
These simple objects come in many different styles and colors. While a lot of the older insulators were made from glass or porcelain, some were made from wood and glass, and even animal parts! You’d be surprised at some of the unusual materials used. The size of the insulator is important too. Smaller ones are used for telephone and telegraph wires, while larger ones are made for high-voltage electrical wires. It’s like having a special section for insulators based on how much voltage they can handle!
Keeping Voltage in Check
When it comes to power lines, the voltage affects how big the insulator needs to be. Electricity can be a bit tricky and might try to jump across a distance. That’s where the design of insulators helps out. Insulators with wide “umbrella” shapes and large lower parts act like careful bouncers at a nightclub, keeping the wires away from the pole and stopping any accidents from happening.
A Surprising Hobby
Believe it or not, collecting insulators is a popular hobby! This started becoming popular in the 1960s when utility companies began burying their wires, leaving a lot of old insulators behind. As the saying goes, one person’s trash is another person’s treasure. People who collect insulators come from all different backgrounds. Some like these glass pieces for how they look and use them to decorate windowsills and gardens, adding a bit of shine to their space. Others look for specific types of insulators. Prices can vary a lot; you might find one for less than a dollar or even get one for free at flea markets!
A Historical Touch
Most insulators that collectors have are between 70 and 145 years old, and some types haven’t been made since the early 1900s. Anything that’s old and no longer being produced often becomes collectible, and insulators are no different. They hold a piece of history and connect us to a time when communication was just starting to grow.
Appreciating the Role of Insulators
The next time you see one of those interesting glass or porcelain insulators on a telephone pole, take a moment to appreciate how important they’ve been in the history of communication. They might seem like old items, but they’ve made a lasting impact on how we connect with each other, whether through a phone call or a quick text message. Who knows? You might even feel inspired to start your own collection and join the many people who find beauty and history in these simple artifacts!
Crews discovered a huge shipwreck underneath the foundations of the World Trade Center Towers after 9/11
Following the finding, archaeologists were left scratching their heads.
When crews responding to the September 11 terrorist attacks discovered a shipwreck, they were astounded.
The World Trade Center terrorist attack site was still being excavated in 2010.
Archaeologists found a ship among the debris; it was only around 22 feet below street level.
It makes sense that the ancient wooden ship raised a lot of concerns. How did it arrive here? Why was it in this location? How did the ship get to be in the center of New York City?
Since then, researchers have unearthed the mysteries surrounding the enigmatic craft.
They were able to determine the age of the shipwreck by analyzing the tree rings on its wooden skeleton.
They learned that the wood from which the vessel was constructed originated in Philadelphia around 1773.
That being said, how in the world did a big wooden ship end up in the center of the city?
The World Trade Center’s exact location was in the Hudson River when Manhattan was initially inhabited.
Researchers are unsure about the cause of the ship’s sinking—a mishap or an accident.
Manhattan’s western shoreline shifted westward as New York built, finally burying the ship under debris and other waste.
Archaeologist Molly McDonald told CNN in 2014: “It’s such an intense site already based on its recent history, so to be in the midst of this urban, modern, very fraught location, and then to be sitting on what was a river bottom, with clams and fish, and the smell of low tide, was really an amazing juxtaposition.”
The ship would have been fully hidden from view by 1818, until the September 11 attacks of 2001.
And when Americans, New Yorkers, and people everywhere else watched in horror as a Boeing 767 filled with 20,000 gallons of jet fuel smashed into the World Trade Center’s northern tower on that terrible day, the ship was well and truly long forgotten.
The 110-story tower had a huge hole in it from the collision, which quickly killed hundreds of people.
An estimated 50,000 people worked in the buildings on a regular weekday.
It was estimated that an additional 140,000 individuals visited the Twin Towers on a daily basis.
It is mind-boggling that the World Trade Center was so big that it got its own zip code, 10048.
2,977 innocent individuals lost their lives as a result of the attacks, while thousands more suffered injuries.
And over the years, a great deal of people have passed by the location without realizing the nautical gem buried beneath.
