When do children look at the stars? In our urban society, few
people look up to contemplate the heavens, and there is so much
light pollution that it is often difficult to see anything (the
weather doesn't help either!). If we can't see the sky, we are
denied some fundamental wonders to experience, and even in the
countryside it is getting more difficult to see the events
'especially near the horizon ' where the events that
were the basis of the calendar, navigation, and time reckoning
occurred. The study of astronomy became an essential part of human
activity, and led to significant developments in a wide variety of
mathematical knowledge. The references below could encourage you to
start something serious!
There are many sites labelled
'astronomy for kids'. A couple of the better ones are:
This is the website of the Astronomy
Magazine section for young people (and adults!) http://www.astronomy.com/asy/default.aspx?c=ss&id=127
Something a bit more technical here:
This site is Astronomy without a Telescope and is much more
This is the homepage for the above
site. All you might want to know!
