so i just received a text from a friend from the other side of the world and i replied to it. less than 2 minutes later he sent another one.

this got me thinking…

…how, by pressing a series of buttons on something smaller than my hand, can someone 6000 miles away instantly read what i have written by him pressing a certain button? how can these couple of sentences circle the globe in less than a few seconds? how can i be heard in another country simply by speaking into a hole at the end of my phone?

this blows my mind!! i’m not looking for scientific explanations but can anyone explain to me how this is possible?

it’s the same with radio. someone talking into a microphone which i can hear while driving in my car…

and don’t even get me started about Sky-pe…
