One of the most important people in the history of aeronautics , [7] Cayley was a pioneer in aeronautical engineering [8] and is credited as the first person to separate the forces of lift and drag , which are in effect on any flight vehicle. Early knowledge of aeronautical engineering was largely empirical with some concepts and skills imported from other branches of engineering.
Many years later after the successful flights by the Wright brothers , the s saw the development of aeronautical engineering through the design of World War I military aircraft. The first definition of aerospace engineering appeared in February Some of the elements of aerospace engineering are: The basis of most of these elements lies in theoretical physics , such as fluid dynamics for aerodynamics or the equations of motion for flight dynamics.
There is also a large empirical component. Historically, this empirical component was derived from testing of scale models and prototypes, either in wind tunnels or in the free atmosphere. More recently, advances in computing have enabled the use of computational fluid dynamics to simulate the behavior of the fluid, reducing time and expense spent on wind-tunnel testing. Those studying hydrodynamics or Hydroacoustics often obtained degrees in Aerospace Engineering. Additionally, aerospace engineering addresses the integration of all components that constitute an aerospace vehicle subsystems including power, aerospace bearings , communications, thermal control , life support , etc.
Aerospace engineering may be studied at the advanced diploma , bachelor's , master's , and Ph. A few departments offer degrees in space-focused astronautical engineering. Some institutions differentiate between aeronautical and astronautical engineering. Graduate degrees are offered in advanced or specialty areas for the aerospace industry. A background in chemistry, physics, computer science and mathematics is important for students pursuing an aerospace engineering degree.
The term " rocket scientist " is sometimes used to describe a person of great intelligence since rocket science is seen as a practice requiring great mental ability, especially technically and mathematically. The term is used ironically in the expression "It's not rocket science" to indicate that a task is simple.
Why I stopped using the phrase “This is not rocket science.” | Hacker News
From Wikipedia, the free encyclopedia. Aerospace Engineer NASA engineers, seen here in mission control during Apollo 13 , worked diligently to protect the lives of the astronauts on the mission. This section needs expansion with: You can help by adding to it. List of aerospace engineering topics. List of aerospace engineering schools.
“It ain't always rocket science, sometimes a door is just a door.”
Nowadays we tend to regard the complex Curiosity landing as ordinary. But the more important point is: It's never pointed in the OP why rocket science is simpler than social problems, e. I think that the reason is that most social problems are "Wicked Problems" http: The most important difference between a problems such as solving religious extremism and putting a satellite in orbit or nuclear fusion or brain surgery is that in the latter case you can isolate affecting factors and study them in relative isolation and sub-problems are well-defined and have well-defined answers, at least compared to social problems.
Rockets used to be hard. See the book "Ignition! Clark for some of the details. Interestingly, poking Google's ngram search suggests that whilst the phrase "rocket science" saw a little use around I've no idea why: DennisP on Oct 18, That's the second time recently I've seen that book mentioned. The first was in a couple reddit comments, with high praise. A little searching will lead you to a pdf if you're willing to channel your inner pirate. The rocket always lands as predicted?
He didn't pay much attention to the Space Shuttle accidents, did he? Perhaps he's referring to ballistics. Rocket science generally refers to designing the rockets, which to this day sometimes blow up, lose engines, spiral off course, and suffer various other catastrophes.
Yes, but relatively rarely, and when they do we can almost always work exactly why they did what they did and exactly what went wrong where to cause that failure. There is no debate as to the science behind the failures of Colombia and Challenger, but there is a lot of debate about what human factors led up to those failures and what to do about them, which rather strengthens his point. They forgot a comma - "The rocket always lands, as predicted.
For many rockets the whole point is that part of them doesn't - see e. Isn't the person being quoted a man? Research, who explains why people exhibit such behavior. Here is my favorite part of his TED talk. Yes, twitter account confirms: Men can have husbands, too, you know.
Percentages are small, and the name was not male. DanBC on Oct 18, Unfortunately this is not true for most of the world. There's a distinction between engineering icy o-rings and science. I believe the author of the article misses the mark on many situations where the expression is used. In the technical domain, when my colleagues or I use the phrase, it's usually in disdainful reference to an inane request or situation where someone can't accomplish or learn a very basic task that they should know due to their lack of effort or attitude. It's not rocket science.
StavrosK on Oct 18, It's odd to me that everyone comments on the phrase "rocket science", when hindsight bias is a much meatier subject to discuss. I've learnt by reading Harry Potter and the Methods of Rationality[1] that hindsight bias is pervasive, yet easy to get rid of. Whenever you find that something is common sense, reverse the outcome and see if it's still common sense or not. If you find both cases equally very likely, then you've just fallen prey to hindsight bias. Here's an excellent post about it: If one solution is obviously extremely likely, all the others must be equally unlikely.
If you've liked the original series, you'll love this. I read this before reading Harry Potter, and now the latter seems childish. Feb 21, Cynthia books view quotes.
