Research paper on the physics behind one of your favorite biological application. Should be based on physics 7 concepts (electricity, magnetism, optics, etc.).
The research paper should include the following!
i) Theory (must describe the physical concept used for the application, feel free to use appropriate equations)
ii) Background history of the Applied application (how the theory is being used for the implementation of the application)
iii) Current state of the application, and future developments (if applicable)
iv) must cite all the sources.
It should be four pages long (double space) with citations provided. You can include pictures and graphs but make them small and only if necessary.
