Spiders are Our Friends by Adrian Galli

One of the most unpopular positions I defend to the death: don’t kill spiders! 

Personally, I don’t find them creepy but I know plenty who do. They find their way into places we humans don’t expect and they surprise us. To be fair to the eight legged creatures, they just want to find some tasty critters to munch on or a safe place to call home—just like us.

Most never pose a threat to us. Even the ones that could harm us might do so because they perceive us as a threat. Funny thing is, they are probably right to fight back—so many of us homosapiens will kill these friendly arachnids on sight.

In all actuality, they are really, really important to the ecosystem. Having some in your home are in fact beneficial. Those meals they seek are other insects and pests that might otherwise be bad for you. They aren't picky—mosquito, ants, mites, whatever they can catch they will likely try to eat.

Spiders don’t damage your property, they won’t burrow into the wood of your house like termites, and a spider usually lives a very secluded life. You’ll likely never find a hive of thousands and thousands of spiders like in the film Arachnophobia.

 
Don’t kill the next spider you see in your home.

Why?Because spiders are an important part of nature and our indoor ecosystem—as well as being fellow organisms in their own right.

Live and let live. And how could you squash a cute spider like this one? He just wants to dance!

Rebranding my 'Blog' page, I've never been a fan of the word. It is ugly and clumsy shortening of 'web' and 'log'—weblog—blog.

My passions: Filmmaking, Photography, Science, Travel, Design, and Technology. Back in the day, I ran a site called Adrian's Gear all about the cool gear I had found. And it is high time to bring that back.

I have no one thing I wish to write about but many. These passions form the sides of this journal and the evolution of AdrianGalli.com.

Welcome to Hexagon.

Voyager 1, Four Decades of Exploration by Adrian Galli

Many people say, “I was born decades too early, I should have been a...” While the past has a certain charm, I’ve always been born of the future. I always say, “I was born 300 years too early, I should have been on the bridge of the Enterprise.” While my life will never take me to distant star systems, encountering the Klingons, or engaging warp drive, at heart, I am explorer and September 5th, 1977 was a date important to humanities exploration of the Universe  

Today, marks forty years since the launch of Voyager 1. Its story is one of exploration and science and to this very moment, it is still transmitting incredible data back to NASA. Not only it this an incredible feet, imagine a car or computer running for four decades with no maintenance, Voyager 1 is the only device made by humanity to have left our solar system and ventured into interstellar space. 

Speeding away from us at 38,000mph (48,000kph) towards a star known as AC +79 3888, about 17.8 lightyears from us. Voyager will lose power long before it reaches that star but the little probe that could will hopefully remain intact.

Aboard Voyager 1 is the Golden Record. Scientist affixed this item to Voyager 1 in hope that one day it would be found by some space fairing life form who could decipher its message. Among the details engraved on the Golden Record is a diagram defining our sun’s location relative to fourteen known pulsars, a binary code to instruct the proper speed by which the record should rotate to play properly, other instruction to play the record, and details about the video portion.

One of my favorite features of the record is the inclusion of Uranium-238. With a half-life of 4.51 billion years, measuring the amount of the daughter element would allow an extraterrestrial to calculate the time Voyager 1 has been in space – a true universal clock. 

Today (September 5, 2017), at a distance of about 140 AU, the power from three radioisotope thermoelectric generators dwindles at a rate of 4 watts per year according to NASA. In 2030, the power it generates will be too little and Voyager 1 will power down forever; an end to the lonely space probe. However, not too far behind is Voyager 1’s sister, Voyager 2, which will also enter interstellar space on its own mission to pass near Sirius.

Further, Pioneer 10 and 11 will also leave our system and a more recent probe, launched in 2006, New Horizons, too, but there is certain romanticism to Voyager 1. It was the first and perhaps the most important of all the space probes in an era when space exploration was at the pinnacle of American, and I argue human, interest and accomplishments.

Voyager 1 will perhaps wander our galaxy for eternity, a monument to human ingenuity and curiosity, a legacy adrift in the Universe.
