    Knot Views

    Interested in playing around with some mathematical knots? Manuel Arala Chaves of the University of Porto in Portugal has created a table illustrating all 75 knots with up to 9 crossings in their standard representation. If your computer can handle LiveGraphics3D, you can manipulate the knots in three dimensions and look at them from different […]

    Waves of Congestion

    You’re confined to a single lane as you drive along a narrow, winding road. The car in front of you suddenly slows, then just as inexplicably accelerates a short time later, only to slow again. As you keep adjusting to the leading car’s erratic speed changes, you sometimes find a clump of vehicles closely tailing […]
