Multi-variable decisions, Stuart Pugh, and donuts

Decisions can be difficult. We often must choose the “best” option from a list of possible alternatives that each possess a unique set of advantages and disadvantages. When buying a car, for example, we will consider factors such as affordability, size, fuel efficiency, appearance, and quality. Rarely is there one alternative that clearly represents the strongest option for every criterion. Instead, we attempt to find an optimal choice that gives us the best mix of qualities based on those factors we deem most important. Continue reading

Design lessons from the Nalgene bottle

Consider the Nalgene. Anyone who has done even a modest amount of camping will be familiar with these colorful bottles. They are ubiquitous on college and university campuses. You will find them in people’s offices, in people’s homes. In short, they are everywhere. This popularity can be ascribed to a number of features such as their durability,[1] their wide mouths, or the way they don’t affect the taste of their contents.

But the Nalgene originally had a much more narrow focus. It was a laboratory container, one of many developed and sold by the Nalge Company of Rochester, New York. Continue reading

Laurentian University coat of arms

Recently, there was an article in University Affairs about heraldry that described the history and symbolism associated with the coats of arms of a few Canadian universities.[1] While Laurentian’s coat of arms was shown and mentioned briefly, its features were not explained in any detail. This omission piqued my interest and spurred a little investigation.

It turns out that there is a Canadian Heraldic Authority (CHA), headed by the Governor General of Canada, that is responsible for administering coats of arms and related symbols in this country. They also maintain a registry that explains the symbolic meaning of the various features. Continue reading

Setting up email or SMS notifications on D2L

We use a piece of software at Laurentian called D2L (formerly known as Desire2Learn). For those who are unfamiliar with it, D2L is what is refered to as a Course Management System (CMS) or a Learning Management System (LMS). Blackboard, Moodle, and Canvas are some of the other popular alternatives within this market segment.

When a student logs into D2L they find entries for each of the courses in which they are enrolled. The amount of material available in each course depends entirely on the instructor. Some elect not to use it at all. I use it extensively for distributing lecture materials and assignments, posting announcements, hosting course-related discussions, and even collecting and marking assignments. Because we use it so much in my classes, I inform the students during the first lecture that they are responsible for staying updated on the news and content available on D2L.

One piece of feedback I have received from students is that they sometimes forget to check the site regularly. Thankfully, D2L has notification features which will automatically send email or text reminders about new content. This post will walk you through how to set up these notifications so that you can remain updated without having to login to D2L on a regular basis. Continue reading

Design lessons from the badminton birdie

One may not naturally associate badminton birdies with space flight, but Burt Rutan saw a connection. A shuttlecock inspired his solution to a significant engineering problem.

The Ansari X-Prize was created in 1996 to spur the development of private space travel. Ten million dollars was offered to the first team capable of designing a re-usable system that could take three people 100 km above the Earth, then return them safely to the ground, and do so twice within a two week period. Rutan’s company Scaled Composites, in collaboration with Microsoft co-founder Paul Allen, developed a vehicle called SpaceShipOne which won the X-Prize in October 2004. Continue reading
