Long ago, before our sleek flat-screen TVs and streaming shows, people’s living rooms were filled with big, boxy televisions that sometimes showed fuzzy “snow.” This static wasn’t a mistake, it was just how older technology, called analog, worked.
Back then, many homes had dishes on their rooftops that pointed up at the sky. These dishes weren’t looking at stars—they were looking at satellites floating 22,500 miles above Earth. Those satellites were placed so high that they matched the speed of Earth’s spin, making them seem like they were standing still in the sky. The dish would catch a signal sent from the TV station, bounce it to the satellite, and then bounce it back down to your house. However, because analog signals could have endless possible values, they sometimes picked up extra “noise” on their way, which showed up as static on the screen.
Then, in 2009, everything changed. TVs stopped using analog signals and switched to digital signals. Instead of sending endless possibilities, digital signals are made only of 1s and 0s, like tiny light switches that are either on or off. Because there are only two choices, there’s no extra “noise” to confuse the picture. That’s why you don’t see static on modern TVs, just a crisp picture or nothing at all.
But here’s something surprising: even long before the internet or televisions, people had already created something digital—the alphabet. Each letter is a set symbol with only a few possible options. If someone writes a messy “A,” you can still figure out that it’s meant to be an “A.” That’s how digital things work: a small set of clear choices.
On the other hand, a painting is like analog. No two people see it the exact same way, and there are an infinite number of possible colors and shades that make it up. There’s no limit to the options, just like the old static-filled signals.
So, the world around us is full of both digital and analog things. Digital technology, such as modern TVs, helps make our lives clearer and simpler, while analog things, such as art, remind us of the endless variety and uniqueness in life. Without realizing it, both have shaped the way we experience the world.
