What makes rocket science hard




















And who said that "One small step for man…" quote? Was it a neuroscientist? No, it was not. Neuroscience: The science and activities of the brain have given rise to all manner of pseudoscience. Indeed, when you consider that all pseudoscience is the product of human invention, the brain is responsible for pseudoscience in general. The placebo effect and confirmation bias has allowed alternative medicine to flourish, the unknown extent of the capabilities of the brain is exploited by psychics and the like, and poorly understood malfunctions in the brain may have potentially altered the course of human history.

That's some powerful neuroscience, there. Rocket science: Essentially "responsible" for moon-landing deniers, rocket science has produced its fair share of pseudoscience, mostly linked to conspiracy theories. Outcome: Pseudoscience stems from the human brain, so neuroscience can claim the bulk of it.

You may see this as a cop out, but you don't get to keep a personal science platform on a high-profile media site by enraging potential readers. That should have been easy to figure out. Come on, it's not quantum mechanics. Dean Burnett usually reserves his neuroscience cheer-leading for Twitter, garwboy. Neuroscience v rocket science: which is biggest and best? When people emphasise how complicated something is, they often compare it to either one or the other, but which one wins?

Neuroscience v rocket science: is this an MRI scan of a brain or a picture from space? Admittedly, the stars give it away somewhat. Outcome: Damn Greenfield! Reuse this content. Skip to main content.

The question is common for young people like myself who are interested in the aviation industry, so let me tell you about how my degree supports my work at To70 Thailand.

When choosing an engineering field to study, aerospace sounds very specific and limited in its usefulness. My Aircraft Design professor often emphasised the similarities between aerospace and systems engineers, since both require splitting systems into subsystems from different fields while simultaneously ensuring that the whole system meets requirements. And because aerospace combines so many other engineering disciplines often all rolled into one class!

The curriculum may vary in different countries, but as you begin to specialise, the reason for that broad foundation becomes clear and the work becomes much more interesting.

My favourite was the laboratory research. Nitrogen tetroxide N 2 O 4 and hydrazine N 2 H 4 are liquids at room temperature and can be stored indefinitely, ready to use. They are hypergolic with one another: they burst into combustion spontaneously on contact, so when used in rocket engines, no igniter is required; this makes them attractive for engines which must restart multiple times.

Unfortunately, both nitrogen tetroxide and hydrazine are highly toxic and must be handled with extreme caution. A wide variety of solid rocket propellants are used. They have both fuel and oxidiser mixed together, and require only an igniter to set them burning. All right, enough with the equations, numbers, and acronyms. We will have no payload: just the rocket itself. Fully packed with propellant, the GEM weighs 33, kg m 0. At burn-out, just 91 seconds later, the final mass m f is but 3, kg.

The 5. Pretty impressive, but what if we want to go to orbit? Forget about it! Orbital velocity in low Earth orbit is around 7.

How hard can it be? With a little algebra we can rewrite the equation as:.
