Episode 131 — Five Years

Adam, Brian, Carmen, and Jeff discuss the importance of accurately estimating time and budget as a practicing engineer. Brian frequently makes estimates as part of his professional duties. Detrimental effects of our anchoring bias are noted by Jeff. We reference lecture notes from Francine Warner of Kennesaw State University in this episode. In making estimates, … Continue reading Episode 139 — Estimation →

We catch up with Sam Feller (who previously joined us in Episode 70), discussing his interests, projects, and latest entrepreneurial ventures. Having left industry to pursue an academic career, Jeff isn’t chomping at the bit to move back into the entrepreneurial world. Our guest for this episode is Sam Feller, a mechanical engineer who may … Continue reading Episode 138 — Still Awkward →

In an episode that was recorded in early October, Adam, Carmen, and Jeff reflect on their summer activities, and on plans for the remaining months of 2017. Carmen spent a lot of his summer traveling, both domestically and internationally. Although he spends a good deal of time dealing with marketing people, Carmen claims that he’s … Continue reading Episode 137 — Late Summer →

Adam, Brian, Carmen, and Jeff consider the boundaries of one’s own competence in this episode of The Engineering Commons. Competencies seem to be driven by past failures, notes Brian. For learning about “magical potions” developed with “unicorn science” (chemical engineering), Brian recommends the NurdRage channel on YouTube. Brian takes a cruel pleasure in seeing Mehdi … Continue reading Episode 136 — Circle of Competence →

In this episode of The Engineering Commons, the gang discusses tailoring a presentation to meet the needs and interests of your intended audience. Adam’s favorite form of communication is an old-fashioned face-to-face conversation. The data throughput of smoke signals is a bit too slow for Carmen’s needs. Jeff suggests flag semaphore as an alternative means … Continue reading Episode 135 — Target Audience →

Adam, Carmen and Jeff discuss how engineering might change by the year 2040 in this episode of The Engineering Commons. Adam hopes to move a little higher into middle management over the next decade… unless he wins the lottery and can immediately proceed to retirement! We begin by looking back 23 years, to what engineering … Continue reading Episode 134 — Twenty Forty →

This episode finds the gang discussing engineering projects that went awry, but did not result in the loss of human life. While map makers include trap streets to catch copyright violators, Adam reassures us he’s never been asked to physically construct such a street. It seems that mapping software sometimes makes traffic worse. At the … Continue reading Episode 133 — Embarrassed Engineer →

We discuss the case of an Oregon man fined for “practicing engineering without a license” in this episode of The Engineering Commons. Both Jeff and Adam have attended a few plays authored by William Shakespeare. A line from Shakespeare’s play Romeo and Juliet is often used to assert that names do not change what something … Continue reading Episode 132 — By Any Other Name →

Chris Gammell returns to The Engineering Commons to discuss how his views on engineering education (and the engineering profession) have evolved over the past five years. Jeff is coming to appreciate that learning is a social event. Massively open online courses (MOOCs) were once thought to be the next “big thing” in education. Our guest … Continue reading Episode 131 — Five Years →

In this episode of The Engineering Commons, we discuss an electromechanical component commonly used to achieve physical motion; the ubiquitous direct-current (DC) motor. Carmen admits to getting turned on by electricity… and sugar! Although differences between engines and motors can be argued, at least one definition claims that an engine converts chemical energy to mechanical … Continue reading Episode 130 — DC Motors →
