Pragmatism Ex Machina

Following the recent news of the Virgin Galactic malfunction and crash I thought I’d write something about these type of endeavours. Many have said limiting these projects would hold back science. Virgin Galactic, SpaceX etc, aren’t scientific pursuits however, but merely joyrides for millionaires. I don’t agree with limiting them either; if people with enough cash want to go into space and peer at the earth that’s great and they’ll have an incredible experience, but they’re not pushing back any scientific frontiers.
If I was offered the prospect of going to Mars and being the first person to set foot on the Martian soil I’d gladly take it, even if it might be a one way ticket. My name would go down in history. I wouldn’t be taking a tiny step towards getting humanity to the stars though.
We’ve just about reached the theoretical efficiency limit of jet engines and chemical rocket engines. We could maybe squeeze another 10% out, but that’s it. Rockets are not going to get people into space in the way space travel is often thought of i.e. beyond Mars, the Solar System or even across the galaxy. This might seem obvious, but it could be that no future technology can take us very far from this massive rock we currently reside on.
A corollary to all the amazing scientific discoveries of the past 150 years is that the knowledge we gained has also put a limit on what we can achieve. We know, for instance, all the stable chemical elements and their isotopes. That there’s an element lighter than hydrogen or a stable element with 300 protons is extremely unlikely if all the universe obeys the same laws (there’s no reason to think it doesn’t). This means there’s a limit on the strength, robustness and longevity of anything you can construct. We don’t know what a lot of the universe is made of but it would be a logical leap too far to say that one day we will know what dark matter/energy is… and we can manipulate it, and it can solve a tangible engineering problem we have. The effects of the fundamental physical forces at a macroscopic level are understood for all practical purposes. If one day electromagnetism and gravity are combined in a unified theory this wouldn’t make getting a payload into orbit any easier.
If science is limitless then you are free to believe anything. This type of thinking is more akin to religious faith rather than scientific thought. Whenever there is an insurmountable problem regarding space travel the argument generally goes that ‘we’ll figure it out in the future’ or ‘if we use this unproven (and often impractical theory) we can do this or that’ or ‘if we can travel at 0.1 times the speed of light then…’ (an ambitious premise to build an argument on). This is akin to an ontological argument; that if we can conceive of an idea then it can exist in reality. This is flawed logic. The idea that mankind has a grand destiny in populating the galaxy and beyond is analogous to a theological framework. It’s instinctive to think this way; we like to think there is a point to our existence and are predestined to greatness, set apart somehow from the natural world.
These statements could come across as overly pessimistic and similar to statements made at the end of the 19th century when some thought every useful object had already been invented. Many point to the car and air travel as proof that seemingly impossible things can be done. The car was not a scientific problem however, it was an engineering one. Small explosions producing a force on a piston, changing its momentum and driving an axle wasn’t outside of known physics and chemistry before the first auto-mobile. The engineering problem of making parts small and robust enough was the major hurdle. Likewise with flight, even though the equations were unknown people knew flight was possible just by looking at nature. Humans are incredibly impressed by their own constructions; the pyramids, skyscrapers, computers etc. Termites and ants have been building giant elaborate constructions for millions of years and the brain is much more complex and efficient than any computer. Through the relatively simple trial and error process of evolution nature has accomplished more than we have in many areas. Yet we think we can manipulate gravitons (not even known to exist), fold space or journey through wormholes.
In fiction there’s often the story of bringing a person from the distant past back to life in the present day. It’s true that person would initially be amazed by the modern world. After a few weeks and months what may strike them is how similar life is however. The main changes that have occurred are that we can journey from place to place quicker, we can exchange information almost instantly and we die less from disease. Major steps forward, but in all other aspects life is generally the same. Electric lights, kettles, fridges etc. are wonderful inventions but they all work using the same fundamental forces and heat exchanges as their crude predecessors.
Christopher Nolan’s space epic Interstellar has just been released at the cinema, which portrays a journey to find a new world after the earth has become unable to produce food. I haven’t seen the film so can’t make any judgement on how good or bad it is. There is a slightly worrying political message in the film that if we ruin the earth and its environment it’s not a major problem because we can just move to a new planet. This set-up is a convenience so the film’s protagonists and the audience can journey into space, but if taken totally seriously seems to indicate some curious priorities on behalf of mankind. I’m not sure if the film addresses the problem that scientists and engineers can’t work out how to produce food after an environmental disaster but can construct an Alcubierre drive or similar enabling faster than light travel (speculative, unproven, impractical). It’s a science fiction film so plot devices can be fantastical without being a major problem, but confusing science fiction with reality can be a problem.
There’s an incredible amount of exciting research at the moment in genetics, neuroscience, biochemistry, robotics, cybernetics etc. that are pushing forward our knowledge of the world and ourselves. Research that seeks to make our lives sustainable and the earth environmentally secure seem to have more to offer in the long term.

TL;DR – I’m not advocating limiting science research. I’m saying that what we know of the natural world limits what we can achieve and our flesh and bone bodies limit what we can endure.

Stripped down style

I’ve just finished reading Wolf Hall by Hilary Mantel. The novel won the Man Booker Prize and a host of other plaudits, so I thought it would be a worthwhile read. The book deals with the life of Thomas Cromwell, the no-nonsense chief minister in Henry VII’s court, and his relationships with the tudor nobility, the church and also his own family.
I enjoyed the novel, especially the natural tone of the dialogue and lack of literary tricks to highten the drama. The uncontrived nature of the story is probably helped by it being partly based on factual events. Too many novels are reverse engineered labyrinths where the author decides the endpoint and works backwards devising meandering paths for the protagonist, nudged on by contrived coincidences. It’s designed to keep the reader off-balance but feels unorganic after a while. Science fiction and fantasy writers are the worst for this: ‘our hero is in a tight spot! is this the end of his adventure? but wait, the sword of amulcar is glowing with energy!’. Every scenario has to have a recherché escape route, every enemy an achilles heel. The missile into the death star moment.
There are problems with Wolf Hall however. Many readers have pointed these problems out, and have sometimes been criticised for doing so. The main problem for the reader is getting lost, but not in the plot. Rather, it’s something more fundamental: the situation, the characters present, and who is speaking. Mantel seems to have made a conscious decision to largely strip away introductions of scene, character and dialogue. This means geographical location and cast are changed surreptitiously and you can be halfway down a page before you realise. Tracking dialogue is like reading a transcript of a real conversion being read out by a single person. This style helps with the flow of the prose as jarring cascades of ‘Mr Soandso said…’, , ‘Miss Thingy whimpered…’ etc can stultify the dialogue. It reminded me of the brutal style of ‘The Road’ by Cormac McCarthy. A style easy to admire but hard to love. The conversations are largely between only two characters in that novel, with one being a child, so it was impossible to lose track as to who is speaking.
A less serious problem is the portrayal of Cromwell himself. For many years he has been portrayed as a bit of a villain and a bully (e.g. A Man for all Seasons by Robert Bolt). Mantel seeks to redress this but describes him in terms of a quintessential modern humanist. He’s a bit too secular and irreligious for that period of time, in my opinion.
I’m looking foward to the next book in the series ‘Bringing up the Bodies’. There’s definite quality in Mantel’s writing and even the infuriating aspects add to its individuality.

 

the vocabulary of vacancies

There’s an old adage in reference to the workplace that says ‘if you can’t give a raise, give a title’. This ploy is often used for members of staff who feel they deserve monetary reward for their hard work, but could be placated with a (sometimes meaningless) upgraded job title. There could be a new adage for the recent trend of making the title of menial/mundane jobs sound more exciting than they are. Maybe ‘if the job’s shit, verjazzle it’. Maybe not. Here’s a few I’ve noticed in the past few weeks.

Pizza Artist – Dominos Pizza
I’m not sure what extent of artistic vision employees can create on a pizza for a customer. Maybe they can roll out a circular expanse of dough and then ride round it on a bicycle like Jackson Pollock freely scattering pepperoni and purée in abstract expression of their inner turmoil. Or maybe cut the vegetables in slender oblongs and arrange them in geometrical tesselation like Mondrian. Probably they’ll just make pizzas based on Domino’s menus and set recipes.

Chilled Colleague – Asda
Do Asda want someone like the Fonz to work alongside their more uptight Richie Cunningham-type staff? Someone to wear a leather jacket and nudge the jukebox when the party starts to drag? I don’t think I’m cool enough to apply for this job.

Hygiene Technician – OCS
The accompanying job description sounded a lot like scrubbing floors.

Apple Genius – Apple Stores
I’ve never been in an Apple store but I’m guessing the staff there aren’t actually of genius level intellect. I was always under the impression Apple products were simple to use. If you need to employ a phalanx of genuises to explain the products maybe they need a re-dedsign to something more user-friendly that any old punter, like you or me, can figure out. Also there is only one personage that comes to mind when discussing genius and apples. Someone who stood on the shoulders of giants. That person is Granny Smith (she perched on altitudinous fellows to reach the apples)

Chief Visionary Officer – Obsidian
This guy sounds important. Try to ingratiate yourself with him. Laugh at his jokes. Frustrate his competitors. Frown at his enemies. Maybe pat his dog.

Biz Dev Guru – Sandbox
Are you an Indus grand master of abbreviation? Apply here.

Nandoca – Nando’s
Work your way to a black belt in chicken preparation under the tutelage of the Nandojo’s peri peri sensei.

Assistant to the Regional Manager – Wernham Hogg
Sounds a lot like Assistant Regional Manager, hence Gareth Keenan’s delusional view of his own importance in The Office.
