The year was 1982. "Food for Thought", a new and innovative course conceived by Drs. David Harpp, Joe Schwarcz & Ariel Fenster.

That's right. McGill presents its very-first MOOC (massive open online course), & the McGill Office for Science and Society (OSS) is up at bat. Are you ready for some Food for Thought?

You Asked: How close to the wind can a conventional sailboat sail? Is there a theoretical limit to the angle to the TRUE wind that a boat can achieve (including lateral drift)? I was taught (many years ago) that the limit is 45%. Is this considered correct today?
Good question. I don't think there's a fundamental limit that is the result of some physical law. I think the 45 degree rule is about **efficiency** - if you sail any closer than this, then you're not taking maximum advantage of the wind. Read More.
Did You Know?
Turbulence during a flight may make plates crash to the floor but it doesn't make planes crash. Airplanes are built to withstand turbulence, but people aren't, so it can make for a most unpleasant experience.
