The Ambiguous Case of the Sine Law

Because the sine of angles between 0º and 180º is cyclical, in some occasions when calculating an angle of a non-right triangle using the sine law it is possible to produce two different solutions. The title of the grade 11 trigonometry lesson, “The Ambiguous Case of the Sine Law,” has always struck me as the possible title of a … [Read more…]

Twin Toddlers

My nephews at 21 months. I had not visited them since their first couple weeks. I am fascinated by their differences and their energy and their freshness. Aari is chubbier, relaxed, thoughtful. Beau is slight, dizzying, curious. Beau falls. Aari gives him his soother.

Two young brothers played their violin and piano duet of O Come, O Come, Emmanuel. Still reeling from … [Read more…]

Jean-Dominique Bauby authored this book by dictating with blinks from his left eye at a hospital an afternoon drive from Paris at Berck-sur-Mer, France. He is paralyzed by a stroke with something called locked-in syndrome. Formerly … [Read more…]
