Chemistry is the study of matter -- and since just about everything we are and do involves matter, chemistry can help us understand and control it.

The problem is stated, a formula is identified, the known quantities are substituted into the formula, the equation is solved for the unknown, and the problem’s question is answered. What problems are you trying to solve right now, are you trying to do something to help people through your chemistry? We have two unknown quantities, length and width. A quarter said that a career in chemistry might encompass "uninteresting work and poor remuneration." Computing has revolutionized the way that we live and the way that we practice science. This content is available over a spectrum of formats that includes journals, books, eBooks, undergraduate textbooks, multi-volume reference works, and innovative databases and online products like Reaxys. Typically, these problems involve two equations representing two trips, two investments, two areas, and so on. Games That Solve Real Problems: Crowdsourcing Biochemistry. For example, there is a need for such data for the design of nuclear waste processing facilities to clean up the environmental issues including radioactive contamination from the processing of nuclear weapons during the Cold War. more than the width, so we can write length as [latex]L=W+6[/latex]. Computational chemistry provides insights into how chemicals can bind in the active site of a protein to block or promote its function. Challenging students with finding solutions to real-world problems will get them excited about science, technology, engineering, and math classes, writes Anne Jolly. They have the tools and resources. By: Caitlin Beddows, Posted on: July 8, 2016. Again computational chemistry can provide critical data and important insights into the chemistry. If the problem of lack of access to clean drinking water is solved, many other related problems can be solved. This is part of the individual medicine approach where physicians will be able to track any issues and treat a single person as he or she ages. Computational chemistry can provide data not available from experiment to enable the design of improved catalysts and acid gas (such as carbon dioxide) capture systems. Note that the square root of [latex]{W}^{2}[/latex] would result in a positive and a negative value. However, we can write the length in terms of the width as [latex]L=W+3[/latex]. I agree that energy is the biggie, but I'd also include finding or making substitutes for the critical elements that are becoming more scarce every day, like helium, gold, lithium, and the useful rare earths. What other problems are there, that are obvious, not so obvious, that people may not know about, that may not help everybody but will still help millions, et c?
