One new approach to teaching mathematics downplays the importance of exact or even approximate numbers. These are said to be less important than understanding broad patterns. A distinguished authority figure apparently agrees:
Global warming is taking place… And the fact is there is probably little to worry about. The increased temperatures will almost certainly be reversed eventually, although how long this will take is unknown.
So writes James Farquhar, in a letter in the May 28 issue of Chemistry and Industry.
Mr. Farquhar identifies himself as: former environment manager at Albright & Wilson and the Tenneco Corporation, Texas; chairman of the CBI Thames Area Environment committee; member of the UK Dept of the Environment Advisory committee; and consultant to the EC.
