Physicists and astronomers study the ways in which various forms of matter and energy interact. Theoretical physicists and astronomers may study the nature of time or the origin of the universe. Some physicists design and perform experiments with sophisticated equipment such as particle accelerators, electron microscopes, and lasers.
Wwind and solar forms of renewable energy, other forms like bioenergy, geothermal, and hydropower are also becoming more competitive when compared with fossil fuels.
Watch how solar can be use for heat the water and as purifier. For more update related science project or agriculture project stay tuned with justscience.com
