Fact of the day: It was at 8.46am local time that the first plane hit the World Trade Center in New York. A total of 2996 people died that day and many more later from the toxic dust. Let us remember all who have died in attacks and in war, and resolve to live in peace and harmony.

Quote: All truths are easy to understand once they are discovered; the point is to discover them. Galileo Galilei (1564 - 1642) Italian physicist and astronomer

Point to ponder: If you cannot understand something, then say it is intuitively obvious.
