Mastering the Art of Hydroponics (STEM) by Ryan M. Taylor ? What is STEM Science Welcome to the initial installment of the Mastering the Art of Hydroponic (STEM) column. Ryan M. Taylor is here to explain what this concept, which has nothing to do with plant physiology or human cells, is really all about… Before anyone gets the wrong idea, STEM does not refer to plant physiology, human cells or metaphorical resistance to something. Rather, it’s the educational acronym for “Science, Technology, Engineering and Mathematics.” A Technology few brief definitions are needed at this point: • Science: both a methodical approach to studying phenomena and the body of knowledge that is accumulated and reproduced. • Technology: a collection of machinery, procedures and tools used to accomplish a goal. In hydroponics, you can thumb through a product catalog and see the diverse array of technology—including the systems themselves, timers, growing substrates, etc.—that can be used to construct your set-up and grow your plants. • Engineering: the application of scientific knowledge and use of technology for practical purposes, such as constructing grow set-ups and growing systems. • Mathematics: the bedrock of physical sciences and engineering that allows us to abstractly quantify properties of system dynamics, structure, etc. 152 Maximum Yield USA | September 2012 STEM Mathematics
