What is the shortest distance between two points?
common knowledge dictates it is a straight line.
Hmmmmm that may not be the reality…
Here we have one of those cases where real reality isn’t like modelled reality, such as in geometry or navigation.
Let me show you a picture to explain.
The shortest distance between two points is over 287,040 kilometres a little more more than the 3 or 4 inches that actually separates them.
So what is going on here?
Two computers that wont talk to each other, but as can be clearly seen they are side by side, with only a couple of inches separating them.
One of them has an important file that is needed by the other, however they have different languages and are of different ages, right?
Now if it wasn’t for the fact that, that one important file needs to pass from one to the other, it wouldn’t make any difference where they are, however what links them, and increases the distance between them, is a single common task that requires both of them to communicate with each other.
Don’t panic there is help, its the internet.
Both computers are connected to the Internet. So we can now send that all important file to my cloud server, somewhere in South Africa.
In order to transfer the file I have to send it to a local server that throws it 35,880 km into the air to an orbiting satellite which in turn drops it the same distance down to my server. The second laptop sends a request to my server via the same satellites to access the file which then sends back the file.
I could have got up from my desk and got a USB cable from the drawer a distance of about 30 feet, plugged them together spanning the 4 inch gap. However my file will have travelled 287,040 kilometres in its entirety in less time than it would take me to connect the two laptops
And the moral of the tail?
In this case, the shortest distance between two points which were 4 inches apart, turned out to be over a quarter of a million kilometres. not the shortest distance between two points but surely the most effective.
