Diagrams and models based on aspect ratio of the material and limiting factors. Especially when it factors into quantum physics where the the active observer disrupts the results.
Nebulas often create stars.
The result of impurities is that you create 'super material' because many pure materials are weak. So scientists often mix materials to create better materials that soot our needs better. e.g. stainless steel
research is often to expensive to do without governments help.
It doesn't wear away easily.
This is a misnomer. Scientists often and do prove their findings, particularly through repetition of an experiment. Scientists cannot prove a negative (reindeer can't fly), but can only prove such under specific conditions (these reindeer can't fly in March). Theories are not said to be proven until they can fully explain a set of conditions. Even then, parts of a theory can be proven, but the whole remains open to refinement.

The scientists often revise the hypothesis.
Very often. Scientists make a lot of mistakes. Cause they don't do some of their experiments with love.
Scientists are often trying to find out whether certain factors changed or remained the same.

Discovery
Not all naturalists are earth scientists and not all earth scientists are naturalists. Some people are both.Naturalists often provide data to scientists, teach, monitor populations, manage parks, create artwork and author books.Earth scientists apply the scientific method to support predictions of change, identify the location of minerals, and manage game resources by studying and analyzing collected data.
Scientists do that because they are skeptical about other scientists' work. They do not usually believe what other scientists have concluded, so other scientists come up with a hypothesis (or simply state a question) as to contradict, or theorize why another scientists' work and conclusions are wrong. In short: Scientists are skeptical and do not believe what another scientist has come up with as a conclusion.
The phrase 'create jobs' is used as often as possible by politicians in speeches and at any other possible time. If there was a new job created every time a politician used this term, the unemployment rate could easily sink lower than zero.
