Lightweight Isotruss Bike Using Carbon Fibers
Engineers used elements of architecture and geometry to create a strong but lightweight triangle-based isotruss bicycle frame. The isotruss is first wound with carbon fiber using a sheet that holds the tension constant. The engineers then hand-wind Kevlar strands over the isotruss. Students might be suprised that geometry is being used in making bike frames. It is also a good introduction into the triangle and its strengths.

"Her Dilemma" by Thomas Hardy (poetry reading)
Hardy did put his heroines in difficult situations and inflict cruel and unusual punishments on them. Fundamentalists have to face the moral dilemma of whether lying is ever justified. This wouldn't be a controversial topic now but it was in Hardy's day. His novel Jude the Obscure met such public outrage that he never wrote another book. After that he put his creative energy into poetry instead. Recently I saw a question put to those who say that lying is fundamentally wrong and never just
