who created a foundation for many more scientists to come and developed theories that went against the teachings of the church. In about 1609‚ Galileo worked with other scientists to come up with the first refracting telescope to help them observe stars‚ planets‚ and moons. Through this telescope‚ Galileo was able to observe the many changes of the Earth’s moon. He also discovered the four major moons

If galleries are the only thing you knew a science centre had‚ then think again! National Science Centre is a hub of science activities and they are presented to you not just through galleries but with an assortment of events and outdoor activities as well. Our calendar notifies us about important days every year like our birthdays‚ any memorable event‚ wedding dates and many more. But we also come across days which are dedicated to remembering a special cause like World Telecommunication Day‚ World

(b) the Earth revolves around the Sun. (c) the tilt of the Earth’s axis changes. (d) their right ascensions constantly change. (e) their declinations constantly change. 2.

enlarge the image of the object and the second magnifies the image formed by the first. It uses light reflected from or passed through the sample being observed to form a magnified image of the object‚ refracting the light with an arrangement of lenses and mirrors similar to those found in telescopes (Houghton Mifflin Company 2003). On the other hand‚ the adjustment of knobs enables exact focus by moving object slightly while the coarse adjustment knob enables the adjustment of stage for the object

Galileo Galilei Galileo Galilei (Pisa‚ February 15‚ 1564 Arcetri‚ January 8‚ 1642)‚ was a Tuscan astronomer‚ philosopher‚ and physicist who is closely associated with the scientific revolution. His achievements include improving the telescope‚ a variety of astronomical observations‚ the first law of motion‚ and supporting Copernicanism effectively. He has been referred to as the "father of modern astronomy‚" as the "father of modern physics‚" and as "father of science." His experimental work
