Even though science is more important today that in the past, there is less in sciences around the world. People who are taking science studies as majors of universities is going down and this is especially important for science teachers. It is harder to find a good sciences teacher now than it was the past. Most people think that it isn't interesting or important. One of the reasons for this is many claims for new discoveries which turn out to be false.
The number of students going to university to study pure and applied sciences is decreasing by about five per cent each year.
