Science Museums and technology centers revolve around scientific achievements, and marvels and their history. To explain complicated inventions, a combination of demonstrations, interactive programs and thought-provoking media are used. Some museums may have exhibits on topics such as computers, aviation, railway museums, physics, astronomy and the animal kingdom.
Also new virtual museums, known as Net Museums, have recently been created. These are usually web sites belonging to real museums and containing photo galleries of items found in those real museums. This new presentation is very useful for people living far away who wish to see the contents of these museums.
