Episode 32 — Fitting In

FittingInIn this episode, we discuss working with those from other technical disciplines, and also touch upon the software skills that engineers should possess.

  • Our guest for this episode is Paul Davis, a software engineer who currently writes jet engine control code.
  • Although there is some dispute about the quotation’s origin, EdsgerDijkstra is frequently credited with proclaiming that “Computer science is not about machines, in the same way that astronomy is not about telescopes. There is an essential unity of mathematics and computer science.”
  • Computer science relies on a number of developments found in discrete mathematics.
  • Paul’s first job after college involved getting Windows 3.1 users connected to the internet via a program called Winsock.
  • His next job found him managing a VAX cluster that ran on the VMS operating system.
  • To gain software development experience, Paul earned a masters degree in Software Engineering from Embry–Riddle Aeronautical University in Daytona Beach, Florida.
  • One tool for managing software development is the Capability Maturity Model (CMM).
  • Paul found the study of formal methods, using Z notation, to be both useful and intellectually challenging.
  • In an old blog post, Jeff reasoned that software engineers are really “engineers.”
  • Since code can be easily changed, tweaking software is often the lowest cost “fix,” but can cause unimagined and unintended consequences.
  • Paul has encountered a number of engineers that use an interface package, such as Simulink, to isolate them from having to generate low level code.
  • Engineers can benefit from learning more about software development, according to Paul, since so much of modern engineering involves programming.
  • Writing code is the best way to learn about coding issues. Paul suggests Python, since it is a widely supported language with a lot of good tutorials.
  • Does anyone actually read these show notes? Perhaps I could simply string together random words like baseball, snowshoe and bubble gum.
  • Jeff struggles to describe a linear variable differential transformer (LVDT), even though he taught a Mechatronics course this past spring. He promises to do better in the future!
  • Paul suggests that software developers specialize in a particular domain, and that physical engineers strengthen their awareness of software concerns.

Episode 31 — Crowdfunding

crowdfundingWe discuss how crowdfunding might influence the future of scientific research in this episode of The Engineering Commons.

  • Adam is willing to fork over a few dollars to further scientific studies of the universe; how about you?
  • Crowdfunding is a means for raising money that has recently been garnering a lot of attention. Websites that cover the crowdfunding phenomenon include Crowd Funding Eye and crowdsourcing.org.
  • A few of the most popular crowdfunding platforms include Kickstarter, Indiegogo and RocketHub. Many other crowdfunding platforms also exist.
  • The Pebble E-Paper Watch campaign raised more than $10 million on Kickstarter last year.
  • Basic Research studies the nature of the universe, without seeking any particular commercial benefit. The bulk of basic research in the United States is funded by the federal government and universities.
  • In contrast, Applied Research attempts to solve practical problems, and is most commonly supported by industrial interests.
  • Projects the size of the cancelled Superconducting Super Collider are obviously too large to be crowdfunded at this point.
  • Brian first became aware of scientific crowdfunding via the Weekly Weinersmith podcast.
  • The #SciFund Challenge helps scientists prepare for crowdfunding, with the actual fundraising campaign being hosted on RocketHub.
  • Jeff recently noticed a Kickstarter project where a Michigan State professor was looking to fund a self-paced course in analog electronics.
  • Microryza is “a platform for scientists to launch and share their research projects with the world.”
  • FundaGeek supports “crowdfunding for innovation.”
  • Medstartr “enables patients, doctors, institutions, partners, and investors to find and fund the best ideas in healthcare and bring them to life.”
  • Petridish “lets you fund promising research projects and join first hand in new discoveries.”
  • iAMscientist “is a global community of science, technology and medical researchers who come together to accelerate research, support career development and drive the distribution of discoveries.”
  • In a recent interview, #SciFund Challenge founder Jai Ranganathan talked about how scientists are adapting to today’s funding environment.
  • Brian notes an Indiegogo campaign that raised more than $700,000 to send a bus monitor on vacation.
  • Jeff mentions the Folding@home project that networks together personal computers from all over the world to form a supercomputer capable of simulating protein folding.
  • A space telescope, with the acronym of ARKYD, is being crowdfunded on Kickstarter with a funding goal of $1 million. In comparison, NASA’s James Webb Space Telescope has already spent more than $3 billion, with the project not yet completed.
  • The plasma technology video that Jeff mentions is a spoof, making light of how scientists might have to go about getting funding in the future.
  • Carmen mentions the YouTube channels of Veritasium and Minute Physics.
  • The Mantis Shrimp seems to be getting more attention in the scientific community these days.
  • The decision on how to allocate dollars to marketing is not an easy one for charities, and Jeff thinks that it will be no easier for scientists trying to raise funds from the general public.
  • The fruit fly has four pairs of chromosomes, and is frequently used in genetics research.
  • Brian notes that Local Motors is an organization that shares information about vehicle design. They are currently crowdsourcing the design of a motorized bike.
  • Jeff has a crazy notion about engineering APIs; Carmen and Brian point out that such “tribal knowledge” already exists as app notes and online forums!

Episode 30 — Travel

GreatWallClayIn this episode we discuss some lessons that our guest, aeronautical engineer Clay Coons, has learned while traveling abroad.

  • Our guest is Clay Coons, an aeronautical engineer who currently works as an applications engineer for Cummins, Inc.
  • Clay attributes a portion of his interest in aeronautical engineering to the 1960’s TV show, My Three Sons.
  • New cars aren’t likely to be found in Clay’s driveway, as most of his family’s vehicles have been driven over 200,000 miles.
  • Clay’s first job with General Dynamics lasted all of a day and a half, before he quit to go work for NASA.
  • Our guest worked about nine years at NASA Lewis Research Center, now known as the Glenn Research Center.
  • Brian references a book by Ben Rich, titled Skunk Works: A Personal Memoir of My Years of Lockheed.
  • Upon leaving NASA, Clay took a position with Cummins working on fuel systems for diesel engines.
  • A position in Mining Applications Engineering opened up about six years after Clay started with Cummins, and he has worked in that group ever since.
  • Clay works with companies such as Hitachi and Komatsu in selecting and optimizing diesel engines for their mining trucks.
  • Carmen mentions an “FAE” job, which stands for Field Applications Engineer.
  • Clay estimates he made about 40 trips his first year as an applications engineer. His trips are now fewer in number, but longer in duration.
  • While at a Siberian diamond mine, our guest worked on trucks while coping with temperatures of -40 degrees F.
  • Eating and drinking with the local staff can go a long way toward building rapport.
  • Clay’s philosophy is that travel is an adventure, and that you should “eat what is put in front of you.”
  • Since mines are frequently located far off the beaten path, Clay is somewhat limited in the amount of sightseeing he can do while on the road.
  • Despite never wanting to be a manager, Clay now has several people reporting to him, so he now has to handle some managerial duties.
  • One of the most unique spots that our guest has visited is the Grasberg mine in Indonesia.
  • Clay’s employer requires engineers working in mining applications to complete Mine Safety and Health Administration (MSHA) training.
  • Although he has traveled to several scenic parts of the world, our guest has also had to travel to less aesthetically pleasing venues, such as the Staten Island landfill.
  • Clay’s least favorite airport is Chicago O’Hare. He thinks the airport in Singapore is definitely the cleanest he has seen.
  • Engineers traveling for the first time should simply enjoy their opportunity to travel, according to our guest.
  • Those wishing to learn more about Clay’s travel adventures can browse his “infrequently updated” blog, Engineered4Life.
