A scientific theory is more elaborated than a simple hypothesis and generally is validated by experiments.
What is the gas scientific name
The scientific symbol for a Bunsen burner is a simple drawing of the device, typically represented by a small circle with a flame on top.
Scientists use the concepts of scale and magnitude to explain phenomena that are very small or very large. These concepts help put the size of objects or events into perspective by comparing them to familiar objects or distances. Scientists also use scientific notation to express very large or very small numbers in a more manageable way.

yes, it is a simple machine
The answer is very simple it is heredity.
Yes.

Apis. quite simple actually. :)
Simple... You don't!
Yes, it does "appear" to be continuous, by the simple fact that it is continuous for all values of the input.

Models and simulations are used for a few simple reasons, cost, health and safety, models and sims a simply cheaper than working with the actual materials, some materials are either explosive, corrosive, poisonous, or radioactive. Though you can only go so far with a simulation, eventually you'll have to break down and use the material itself to perform the study, that is the only sure way to get accurate result.
