Society has developed an obsession with wanting to see things before they believe them. So much of new technology is designed to help expand people’s ways of seeing things. I figured the most interesting device to talk about would be the radar. The radar is neat because it tells a person about things that they cannot see. Submarines use radar because under water it’s much harder to see things. With radar everything within the ocean is now known. The radar allows people to see in places that would otherwise be impossible to see. This is not only fascinating but also quite useful places like an ocean or cave are now able to explore, allowing people to discover things that were never before possible to explore. The military uses radar especially because of its discreteness and its usefulness, knowing where the enemy is, is crucial for an army. Imagining how the military has benefitted from the radar is astonishing.
