Earlier scientists made designs of the thing they wanted to invent. But some scientists didnt succeeded in inventing them. And some succeeded. Thomas Edison invented electricity.

Since glass was invented, the scientists were able to create the microscope. If this was never invented, the scientists would never have been able to discover cells.
A model can be useful by helping scientists study and understand things that are complex or can't be observed directly. It allows scientists to visualize and examine things that might not otherwise be physically accessible i.e. anything microscopic.
Someone help me out and send me a credible source citing this. I am curious about the percentage of American scientists that are emplyed, directly or indirectly, by the military?!

Directly: physicists Indirectly: scientists
Scientist research hurricanes by flying instrument laden airplanes directly into the storms. They also study them from the ground and from satellites.
Because humans cant directly access the sun, scientist study it by usinq a satellite called SOHO.
political scientist
A geologist studies rocks and what the earth is made of. A petrologist is someone who looks at rocks directly.
Most scientists believe that birds evolved directly from bipedal, terrestrial dinosaurs.
Scientists can use anemometers and Doppler radar to measure winds directly. It is also possible to estimate wind speeds with satellite imagery of cloud tops.
Sensors
In cases where things are on such a huge scale that it becomes hard for scientists to study, it's important for a scientist to construct a model. Scientists create models to learn about complex phenomenon and to simulate real conditions. For example, it may be easier to study global warming on a small model than studying it across the entire earth.
