Radio Waves

Radio waves are the longest of the electromagnetic waves. Radio waves are over a football field long. They are the waves that radio stations use to send music across their channels. "During a live broadcast in New York, the music will reach listeners in California a fraction of a second before it can be heard by the New York audience sitting in the back of the concert hall"(University of Michigan The Basic Facts About Radio Waves). These waves are formed by molecules vibrating slowly.

Radio waves are so big that a 64 meter satellite dish can see as much as a backyard telescope clearly. That's why, as you can maybe see in this picture, they have fields of satellite dishes to get a clear picture of space. Radio waves can also have harmful effects on your body. Scientists have found that radio waves after prolonged exposure has a very small possibility of increasing your chance to get a brain tumor. You can get this from telephones or headphones.

Radio waves can help us see gases that you can't see with the naked eye like the above picture which is showing carbon monoxide in our galaxy the milky way. "By studying the radio waves originating from these sources, astronomers can learn about their composition, structure, and motion"(NASA)

Aquatic Science

Marine biology is the study of aquatic animals. I want to be a marine biologist because I like oceans and lakes, I like to fish and I like to swim. My favorite fish is a large mouth bass because they are a challenge to catch because they are strong and fast. I would also love to discover a new species or find the cure for cancer in some fish. It fits my learning style because I'm actively learning by observing specimens or scuba diving and looking new species and interacting with them. A goal of mine is to help marine life survive when humans continuously pollute the ocean or any other marine habitat.

According to MarineBio.org "marine biology could have started in 1200 BC when the Phoenicians began ocean voyages." However it wasn't until Aristotle in 384-322 BC made observations and species were identified. Modern day marine biology wasn't started until James Cook mapped unknown waters and described unknown plants and organisms that he saw. Since marine biology is so diverse scientists usually only pick one area such as fishery or rehabilitation or many more. According to What Does a Marine Biologist Do? marine biologists don't handle marine mammals.

In the future I believe that we will be able to go deeper and discover more species of fish. Maybe even discover fish that were once believed to be extinct. Like the prehistoric shark found in Asia that died while trying to observe it, even though they were trying to keep it alive.
