Engineering vs. Science
What’s the difference? Generally, Science is the study of the physical world, while Engineering applies scientific knowledge to design processes, structures or equipment. Both Engineers and Scientists will have a strong knowledge of science, mathematics and technology, but Engineering students will learn to apply these principles to designing creative solutions to Engineering challenges. As explained above, it's more shades of grey than black and white, but in essence, science is about exploring the universe (physically and mathematically) to learn more about it. Engineering is about learning, inventing and developing solutions to real problems. In the latter, more often than not, it is to meet human needs for food, shelter, transportation, healthcare, etc. A researcher might determine that a certain compound is effective in fighting a disease. Engineers would design the delivery systems as well as the production methods and machinery so that the researcher's discovery can actually be applied to help people. A microbiologist might determine that a certain microbe will digest a toxic chemical and turn it into something benign. Engineers would design the systems and machinery that would make it possible to process those chemicals using that microbe.

Science vs. Engineering vs. Technology
Scientists seek to understand the natural world, and often need new tools to help discover the answers. Engineers use scientific discoveries to design products and processes that Technologies (products and processes) are the result of engineered designs. They are created by technicians to solve societal needs and wants. SCIENCE meet society’s needs.

A Problem Describe three entirely different (but practical) ways for determining the area of the darkened region to within 0.1%. Pick one. Then deduce the area (in cm2). Would a different method give a more accurate result with less effort? Explain. Might one method be better for rough estimates, another better for precise estimates. Explain. Does the effectiveness of your methods depend on the shape of the figure? Explain.

Some possibe answers: 1) Superpose a finely-spaced grid over the figure and count squares 2) Cut out the figure and weigh it. Then compare that weight to that of a piece of paper of known area. If the weight is too small to be measured with an available scale, transfer the figure to another piece of uniformly-dense material which is in the range of your scale. 3) Throw darts (figuratively, of course). Draw a rectangle (whose area can be calculated) which completely encloses the figure. Pick random points within the rectangle and count which ones fall within the darkened figure. The ratio of the number of those points within the darkened area to those within the entire rectangle can be used to estimate the darkened area. (Monte-Carlo integration.)

More possible answers. . . 4) Divide the darkened figure into local regions which can be piecewise integrated numerically. 5) Use a “polar planimeter”—a gadget which mechanically integrates the area defined by a closed curve. (How does a planimeter work?) 6) Draw a rectangle on the darkened region of known area. Computer-scan the darkened figure. Write a program to count the number of pixels of the darkened color. Compare that number with those pixels within the rectangle. 7) Build a container whose cross-section is that of the darkened figure. Fill the container with 1000cc of water and measure the water level in the container.
