Rocket science is a colloquial term for aerospace engineering and orbital mechanics.. It may also include the chemistry and engineering behind rockets.. In popular terminology, it's not rocket science is a layperson's passive aggressive phrase uttered meaning something that is not difficult to understand to attack one's inactions that is a byproduct of anti-intellectualism.
The design and construction of rockets. The hobbyist or (semi-)professional use of model rockets; Aerospace engineering, also known as rocket science; Amateur rocketry, a hobby in which participants experiment with fuels or custom rocket motors
The term is used ironically in the expression "It's not rocket science" to indicate that a task is simple. [27] Strictly speaking, the use of "science" in "rocket science" is a misnomer since science is about understanding the origins, nature, and behavior of the universe; engineering is about using scientific and engineering principles to ...
Where does the term "rocket scientist" come from, and does it have a wider meaning than just "very smart" (or "designing rockets")? —Preceding unsigned comment added by 80.202.125.146 (talk • contribs) It means dealing with rockets. Thus became the term rocket science. See how it all works out. Because a rocket scientist deals with ROCKETS.
Multistage rocket – or step rocket [153] is a launch vehicle that uses two or more rocket stages, each of which contains its own engines and propellant. A tandem or serial stage is mounted on top of another stage; a parallel stage is attached alongside another stage.
"Rocket science" in finance is a metaphor for activity carried out by specialised quantitative staff to provide detailed output from mathematical modeling and computational simulations to support investment decisions.
The phrase "survival of the fittest" refers to biological fitness, not physical fitness. Biological fitness is the quantitative measure of individual reproductive success, e.g. the tendency of lineages containing individuals that produce more offspring in a particular environment to persist and thrive in that environment.
Because of the geocentric factor of g 0 in the equation for specific impulse, many prefer an alternative definition. The specific impulse of a rocket can be defined in terms of thrust per unit mass flow of propellant. This is an equally valid (and in some ways somewhat simpler) way of defining the effectiveness of a rocket propellant.
