Engineers and Scientists

By: John S. Usher, Associate Dean

My last blog post basically laid out the idea that engineers play a role in the design of just about every man-made object that we see in our daily lives.  I often hear people say that engineers “apply science”, that is, take the findings from scientists like biologists, geologists, chemists, physicists, mathematicians, and more, and apply those scientific concepts to solve problems.  In some cases that is true.  However, I would argue that it much more commonly goes the other way around.  Engineers usually design working systems long before the science is ever understood.

Take for example the steam engine, arguably one of the greatest inventions of all time, and the one which dramatically lead to the Industrial Revolution in the United States.   In 1712 the first commercially successful steam engine was developed by Thomas Newcomen.  The machine operated,  but was crude and very little of the input energy was converted to actual work, with as much as 80% wasted as heat.   Much later in the century, James Watt, (yes, that “watt” as in a 60-watt light bulb) worked as instrument maker at the University of Glasgow.  He was shown a small model of the Newcomen “atmospheric  engine”.  Watt studied it and in 1765 realized it could be greatly improved by introducing an external condenser.  Watt became famous for his steam engine designs as they became the backbone upon which the American mass production was built.

Yet, the actual science underlying the steam engine, namely “thermodynamics” was virtually non-existent in the late 1700’s.   Sadi Carnot, the so called Father of Thermodynamics, published Reflections on the Motive Power of Fire in 1824, nearly a half century after Watt’s findings were well known.  The first and second laws of thermodynamics were not known until the late 1850s, based on the works of William Rankine, Rudolf Clausius, and William Thomson (Lord Kelvin).  Rankine’s thermodynamic textbook, the first of its kind, was not written until 1859, nearly 100 years after steam engines were commonplace.

Now, I will admit, this is but one example of science trailing engineering, but we can see similar results in many other fields such as electro-magnetism, computer science, chemistry, medicine and more.  Look no further than the work of Steve Jobs and Bill Gates and their success with building and selling complex computers while the field of computer science was still forming.  Again,  we see the engineer “tinkerer” in the garage making an invention work, to improve the quality of life for someone,  without the benefit of well-formed scientific principles to help guide the design process.

Fortunately, we are now seeing the lines between science and engineering blur significantly, especially on the cutting edges of additive manufacturing, nanotechnology, genetics and bioinformatics, data analytics and cyber enable discovery.   Scientists and engineers now work side by side to unlock the mysteries of mother nature and find ways to apply them to our new technological world.   I am enthusiastic and excited about the science and engineering professions and the roles they will play in solving some of the world’s most challenging problems, including, disease, poverty, terrorism, energy, sustainability, and more.

Electrical and Computer Engineering Dept. Welcomes New Students

Welcome incoming freshmen!  We hope that your studies are off to a great start. We understand that as someone who is new to the Speed School, you still may be unsure what engineering field is best for you.  To help you make your decision, we’d like to introduce you to the Electrical and Computer Engineering department, and tell you a little bit about what we have to offer.

What is Electrical and Computer Engineering?

Speed School's Plug-in Hybrid Research Vehicle

Electrical and Computer Engineering students conduct a variety of research on Speed School’s Plug-in Hybrid Research Vehicle

Electrical engineers study applications of electricity, electronics, and electromagnetism.  This encompasses a wide range of fascinating topics including electronics, power systems, control systems, image processing, signal processing, communications, and micro/nanoscale electronics.  Students in the Electrical and Computer Engineering Department learn both hardware design and the programming and logic design required to operate the hardware.  For example, ECE students recently developed a battery management system for electric vehicles which requires both the sensor hardware to interface with the battery cells and the software to manage and interpret the measured data.

Is ECE the right fit for me?

If you are interested in both hardware and software design, the ECE department is the place for you.  ECE graduates obtain high-paying jobs in microelectronic design, controls systems, power systems, and process engineering.  You’ll find recent ECE graduates working for large local companies (General Electric, LG&E, KU, and UPS); high flying local start-ups (QSR Automation and Genscape), and well known national corporations (Intel, IBM, Micron, and Google).
