Living in a Technicolor Universe

In the past, we can only see black and white images on the television, but now we can see colorful pictures on the HDTV like the colors we see in reality. And now, the scientists can even use new technologies to take picture of the universe, which at first we can only see it in black and white. And with these new technologies we can see the Milky Way in bright color, such as red, green, and blue. These three colors are the primary of colors. In this age of digital photography, people have forgotten that photography is science not art; it is the tool that we use to explore the things that we don’t know about this world.

This article is related to both science and biology, because this is talking about the spectrum that we will receive in our vision. In biology, we can know that our brain assembles a full color image with millions of hues from signals by three different types of receptor cells in our eyes. This is also related to science is because many of those celestial pictures that look colorful in photos is gray when you see it just with your eyes.

We should care about this information because this is a type of technology that shows how human are starting to improve from natural to technical. And it is about how this world starting to use technologies to help us remember some of the great images in our life.
