"By encouraging, or even requiring, students to take stands where they have neither the knowledge nor the intellectual training to seriously examine complex issues, teachers promote the expression of unsubstantiated opinions, the venting of uninformed emotions, and the habit of acting on those opinions and emotions, while ignoring or dismissing opposing views, without having either the intellectual equipment or the personal experience to weigh one view against another in any serious way."

Taking a Break

Source: http://earth.nullschool.net/#current/wind/surface/level/orthographic=-14.76,84.65,349
































My apologies to any regular visitors here, but I am taking a break from blogging for another couple of weeks or so.  In the meantime, here is an entrancing site showing recently estimated surface winds in an animation (with numerical values for speed and direction at any point clicked).  The view can be rotated and zoomed, and additional computer-model generated fields can be added (click on 'earth' at bottom left to get the menu):

Note added 3rd July.  The model gives a dramatic picture of tropical storm Arthur's surface winds off the east coast of the States:  http://earth.nullschool.net/#current/wind/surface/level/orthographic=-73.54,30.96,1512
