Engineering 7 Building Impressions

I was at a conference and missed the official E7 building opening, but below is a video showing some of the facility highlights.  I walk through the building frequently, and I really like the environment.  Nice open spaces, well lit, great and vibrant “energy”.  There are always people around, talking, having events, and working together in one of the many gathering areas, drawing diagrams on the walls.  Definitely seems like a pleasurable place to be.

The Burden of the Iron Ring

A typical Iron Ring.

As some people know, Canadian engineers usually choose to wear an Iron Ring, as illustrated in the picture, on the small finger of their “working” hand.  Actually, it’s now usually stainless steel, and so about 72% iron, 18% chromium, 8% nickel and some other elements.  It is originally a Canadian invention, so engineers in the U.S. and elsewhere are often unaware of it.  What is its significance?  Let’s start with what it is Not supposed to be about:

  • It is not a reward from the university for finishing an engineering program.
  • It is not a status symbol.
  • It is not a sign of belonging to some prestigious or secret society.
  • It is not an indicator of any competence or qualification.

So what is it all about?  First, consider its history… Continue reading

Engineering Failure Rates-Redux

Here’s an update on a popular old post, with some new data and comments.

I’m never quite sure why people ask about failure rates, or what they are expecting.  Do they want to hear that the failure rate is high, so they are convinced it’s a tough (and therefore good) program?  Or maybe they don’t want the failure rate to be high, because they are concerned that they won’t be successful?  I’m not sure what the motivation for the question is, but anyways let’s examine failure rates.  Continue reading

German Baking

Waterloo Region has a long history of German immigration and influence since its initial settlement, leading to place names like Berlin (now Kitchener), New Hamburg, Baden, and local events like Oktoberfest.  Around the area you can find various places with German-style cuisine and products including at the bakery featured in this local news video link:  https://kitchener.ctvnews.ca/video?clipId=1477166   From personal experience, their Christmas Stollen bread and chocolates are highly addictive.  But what does this have to do with chemical engineering?
