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!
Sad news about Brad Pitt. The announcement was made by the great actor himself:
Actor Brad Pitt revealed in a recent interview that he suffers from prosopagnosia, a rare neurological disorder also known as “facial blindness.”
Dani Blum describes the disorder’s signs, causes, and remedies in an article for the New York Times.
Borna Bonakdarpour, a behavioral neurologist at Northwestern Medicine, claims that face blindness—not color blindness or general vision impairment—is the main symptom of prosopagnosia.
The National Institute of Neurological Disorders and Stroke states that there is no connection between the illness and memory loss, vision problems, or learning impairments.
Blum continues, “It is not the same as forgetting or occasionally having trouble finding the correct word.
The severity of prosopagnosia will differ from person to person.
For instance, some people might have problems identifying a familiar face, such as that of a close friend or relative, while others might have trouble identifying their own reflection.
Additionally, some people might not be able to distinguish between faces and objects.
Notably, some data indicates that individuals with prosopagnosia may have chronic anxiety or depression due to the loneliness and fear that are frequently associated with the illness.
Blum notes that some people avoid contact with family members and other loved ones out of concern that they won’t be able to properly recognize or acknowledge them.
“Navigating basic social relationships with prosopagnosia can become difficult,” she says.
Pitt admitted that he has trouble recognizing people’s faces for years in a recent interview with GQ, despite never having gotten a formal prosopagnosia diagnosis.
In fact, Pitt claimed in a 2013 interview with Esquire that his difficulty recognizing people’s appearances was so great that it frequently made him want to isolate himself.
He explained, “That’s why I stay at home.
What is the condition’s cause?
People who are diagnosed with prosopagnosia often fall into one of two categories: either they are born with it or they acquire it.
However, estimations reveal that as many as one in every 50 people may struggle with some lifetime form of the disorder, and experts hypothesize that it may run in families.
According to Blum, research “suggests that congenital, or lifelong, prosopagnosia is less prevalent.”
According to Andrey Stojic, director of general neurology at the Cleveland Clinic, children born with the illness “don’t seem to have any visible structural abnormality” in the brain.
Notably, doctors don’t fully understand what causes congenital prosopagnosia because there aren’t any obvious brain lesions in persons who have it.
In contrast, people who develop prosopagnosia later in life may have brain abnormalities brought on by a trauma or head injury.
According to Bonakdarpour, individuals can also develop prosopagnosia while dealing with Alzheimer’s illness or following a stroke.
What therapies are available for prosopagnosia?
Prosopagnosia is now untreatable, according to Bonakdarpour. The problem can be treated, though.
People who have the syndrome frequently attempt to distinguish between people by focusing on physical characteristics like hair color, gait, or voice.
