Martians

The Martian.

I read this a couple weekends ago. Guy at work recommended it. Mom gave me a copy because her "book club" group was reading it; I think that was because they were working on book/movie combinations.

Mom couldn't finish it. Too much sciencey-numbery stuff going on--not her cuppa.

I found three things annoying. Seriously annoying.


1. All that number chatter was distracting in the wrong way. And I understood all of it. It read too much like someone juvenile's private lab notebook/journal.


2. When you work for NASA, and you're an astronaut, and male, you are very nearly for sure an Eagle Scout. Almost all have been.

Problem is, you're also a Rocket Scientist. And when you're a Rocket Scientist, all problems get Rocket Science solutions.

So I'm on page 5, everyone else is gone, and our hero has recovered from the accident enough to walk around, and is in pursuit of repairing his radio, so he can tell NASA he's alive.

This is brainless. It's a Rocket Science solution, when he needs a Boy Scout solution. It does NOT take an Advanced Degree(tm) to figure this out.

That solution is to go outside an pile rocks up to make letters to spell out "Injured. Still alive." and a date. Granted that's one-way comm, but you do that first, before figuring out how to fix the radio. And later he can go out and spell more words.

Takes to page 160 before that occurs to him. Page 160. Or 170, I forget.

NASA has a dozen low-orbit satellites around Mars, and there's only 15 mins/day when the ground-site is not in visual range of one of them. So a REAL Rocket Scientist back at NASA would have been looking at the ground site as soon as the sand-storm passed, to see what remained. THIS NASA waits 30 days, and even then they aren't running change-detection software on the images, someone has to eyeball a detail or two, and THAT doesn't happen immediately.

And how come the spaceship that departs doesn't have a telescope/camera that can point at the landing site to look at the storm damage? No visual sensors that look backwards? Seriously? no comm to the satellites?


3. And then when he drives out to Pathfinder/Sojourner, he complains about navigating over a featureless but rocky terrain via dead-reckoning. He complains about there being no natural landmarks, and of course there's no GPS. And no compass, either, because there's no iron core to the planet, no planetary magnetic field, yadda, yadda...

What a knucklehead. Once again, you need a Boy Scout solution. If there are no landmarks, MAKE SOME. Pile up rocks every mile, in a straight line from the last couple of piles, you can go in a straight line a long ways. You're guaranteed to drift somewhat, but it'll be close. Pretty sure I learned this idea in 1970. Maybe 69.

He thinks of that on the way back. Well past when he should have been making them.

-----

Yeesh. I hope the movie is better. Well, you know he isn't going to go out and pile rocks up.

And I hope my tax dollars that go to NASA are helping them understand that they need multiple backup systems and alternatives for these sort of difficulties. The army has man-portable radios with funky antennas that fold up into tiny spaces. The landing site ought to have a wide variety of stuff dropped, with extras, especially comm gear.

Is our President read?

Just a week ago, Richard Cohen, writing in the Washington Post, reacts to an op-ed piece by Karl Rove some days earlier that I didn't see, asserting that apparently George W Bush reads A LOT. Apparently something like 100 books per year.

That's two per week. Really? Shouldn't take an Advanced Degree to figure this out...

For comparison:

I have been a heavy reader since about 1972 or so. Prior to that I just didn't have enough access. About 1970 or so I began to have enough of my own books that I was re-reading them a lot, in addition to new ones. Mom took us to the library fairly often, as she was a heavy reader too (from having been stuck in bed for a year as a child, apparently with TB, although apparently decades later that was debunked).

Since 1972 I've read about 3000 books. I still have most of them. That's almost two per week. The shortest ones are probably 125 pages. The longest, over a thousand pages.

I read fast. Damn fast.

In 5th grade I had a nearly unique experience in school--all the 5th-graders took speed-reading. This was in Montgomery, Alabama, in 1968/69, not a location you connect with advanced thinking like this...I'm not aware of this happening anywhere else, really. i was only there for a year, but this was almost unimaginably valuable. (I was back there in 10th grade, and took typing, comparably valuable.)

The scoop: we learn to read by reading aloud. (Think back on your earliest years in school, and before.) So we read at the same speed we talk. On average, this is about 150 words per minute. Everyone in my class started speed-reading training at 150 words a minute. The trick to going faster, in your brain, is that you have to decouple reading and speaking. This is doable by most folks, and pretty much everyone can progress to about 300 words a minute. This is roughly one page in a novel every minute (a page in a printed book usually has about 300 words, I've counted this a number of times in the past; it varies with font-size, but 300 is a good approx). I think I remember everyone in my class being at least at 300 by the end of the school year.

(Lacking speed-reading training, you don't read faster than you talk, and I don't mean the "Evelyn Wood" noise, that isn't really speed reading, but it too requires you to decouple from your speech.)

How was this done? They had a film-strip-like machine that would move a sliding box across a line of text, L to R, then repeat with a new line of text. (There's a computer program that more or less duplicates this, called "Ace Reader"; the sliding box motion is jerky rather than smooth, I found it jarring to try to read that way.) You have to move your eyes to follow the box, so you begin to separate eye movement and subconscious vocalizing. The complete text was a story. You'd take a quiz at the end. High enough score on the quiz, and you moved ahead 25 words/min the next week. The machine's speed incremented in 25 words/minute quanta. So we only did the jumps once a week. At the beginning of the training everyone is at 150. Next week, some still are, some have moved on. By the end of the school year, the spread has increased, and there are kids at most speeds. Nearly everyone has moved beyond 150. I am in the fastest group, at 625, along with 2 or 3 others. Yes--I read 4X faster than I did before.

Damn fast. I still read pretty fast now, but it's variable, depending on the content. A technical manual is a slow read; Janet Evanovich is fast, maybe even faster than 600...

Which means that most novels unfold for me at the pace of a theatrical movie. AND, it means that reading 100 in a year isn't that hard or unlikely. Altho these days I'm busy enough with other things that I don't read that many. Suppose you read one page/min. Suppose the average book is 300 pages, so Bush reads 600 pp/week. Roughly 100 per day, or 100 minutes per day. Does he actually have that kind of time?

But apparently in this Karl Rove article they've been keeping a list of them (which sounds a bit artificial to being with). I haven't seen the list, apparently Cohen has. Apparently the list content has its own interesting features, but that's his discussion. My blog entry argues against his even having done the reading, regardless of what it was.

I don't even have a list of what books I've *bought* in the last year, much less read.

But wait...what did Rove mean by "read"? Did Bush read every word? Or just the first paragraph in the chapters? Skim the chapters? If we assume he reads at 150, then he didn't read 600 pp/week. The President just would not have that kind of time, that's about 3 hours per day. Any more, *I* don't manage to have 3 hours/day for it (although 100 pp takes me < 1 hour).

Cohen's article is about the books themselves. Apparently they are biographies, and their thematic content is such that they would be reinforcing Bush's self-image, and offering some personal vindication for his actions as President. Are there in fact 500+ books like that so that one *could* read that many? That too strikes me as unlikely--but I can imagine it, and if there's really a list...

My conclusion: the mechanics of it indicate that Bush does not, and has not, read 100 books per year. (Of course, if he's had that same speed-reading training I have, well, maybe he did.)


(Aside: why I think this reading machine does this well: our eyes/brains are attracted to motion. Why? I think it's probably ancient racial memory--things that are moving could be predators, so we need to focus on them. There's an interesting bit of imagery/video I'm thinking of here; it begins with a still photo, mostly of non-uniform vertical lines, but when you see part of it move you are able to resolve that it is a tiger (vertical stripes) obscured by nearly-vertical vegetation leaves; no motion = no danger, motion means the tiger (danger) needs to be watched.)

Science Fiction novels

I encountered this again this past week...having begun reading David Weber's "Off Armageddon Reef" -- it's clear where an author's real knowledge/experience are, and usually clear where it's not. His seems to be nautical, and naval, in the time-frame of 1400-1850...that era of human naval battles and tech advances plays heavily in the middle of the book.

What's also clearly NOT his expertise is at the beginning. Book starts in roughly 2430 AD. i.e., just over 400 years from now. Tech advances between now and then are only vaguely imaginable right now. Think backwards 400 years. Jamestown has just been colonized the year before. Shakespeare is still writing. Galileo has NOT yet published his round-earth and heliocentric writings--the earth is still flat, in essence. Electronics, computing, nanotech--all inconceivable and unexplainable. What tech will exist 400 years from now?

At one point Weber says something along the lines of "they couldn't smuggle a computer out because it was too big". I'm sorry, in 400 years computers won't exist the way we think of them now, and they darned sure won't be big. My guess is that long before then computers will have evolved into nanites that essentially exist everywhere, in unimaginable quantities. They will run through your veins. They will BE your clothes, and will dynamically change color/style/shape. Your nanites will be DNA-reconfiguring, protective. The internet won't exist as this separate thing we now have, it will be ubiquitous.

But his book is predicated on things not happening like that...which leads to my central complaint. If you are an author, but not a tech expert, HIRE someone who IS a tech expert, and have that person read your book from early on, so you don't write something that is so far off-target.

Weber's book is enjoyable enough, kind of a Hornblower-on-another-planet story. and the premise is totally dependent on things being pre-steam-era low-tech. So the story is really about post-Renaissance but still feudal politics and religion. You've read THAT before...

But the main character turns out to have to be a recorded personality installed in a very strong robot...if such robots exist, why did they not fight the battle against the aliens that's in chapter one? Said robots don't need O2, don't need food, don't sleep. So they don't need spaceships anything like what people would need...so they could be fairly bizarre looking, incorporate much funkier designs, no worry about things like life support, radiation shielding, low-gravity propulsion...your largest issue would be micro-particles ripping holes in spaceships.

So if you can't get the tech details straight, LEAVE THEM OUT! and don't base the story on premises that couldn't possible be true...this one: the aliens nearly wiped out humanity, and will be around to finish the job if they detect any RF signals from far far away. So I expect that by 2432 AD, or 3200 AD, there probably won't be any more RF anyway. What would be the point? Networks will have evolved from copper to fiber to quantum long before...broadcast will have gone from RF to cable to fiber to __? Satellite comm will be burst-mode laser soon, and quantum eventually. So no RF to detect anyway. Sorry--premise doesn't hold water from the get-go.

favorite things...

there's only one thing I like more than reading...but I'm probably not writing about that here...primarily I read science fiction. Being an engineer and software jockey, that shouldn't be too surprising.

finally read all the titles by Charles Stross that I have (Timelike Dip, Accelerando, Glasshouse, OHMOS)...he's done more, but mostly short stories in the mags, and things under contract but not yet in print. See his FAQ for more info. a little bit of his writing is actually on his website.

Accelerando is absolutely amazing...wish I'd written it...the wild-n-crazy-idea density in this novel is almost off the scale, like nothing you've ever read. (it originated as a series of short stories) The funky ideas roll off (like the classic, oft-mentioned Heinlein "the door dilated", which was about the only time Heinlein tossed off something like that) at a pace you've never seen before. read the electronic version here.

All the stories I read have some inter-related flavor (incl use of certain phrases), they are all about "the singularity", a point in time (probably in the future, but perhaps the recent past, too) beyond which it is no longer possible to imagine what the future is going to be like, because the rate of change due to technological advances is so high that you are future-shocked continuously. Bring it on, I say--can't happen to soon.

Stross handles that all like it's a walk in the park. We are certainly approaching that time, I'd argue that it's this century, because we are basically progressing in terms of computing and biotech at an unbelievable speed, and the convergence of those two things is going to happen soon.

Timelike Diplomacy is only a little based on the singularity. Accelerando is ALL about it, OHMOS is differently based on it (mixing tech with the occult -- not hard to imagine, "sufficiently advanced tech = magic")

Stross has been a computer jockey, too...in the stories I read, he mentions two programming languages, one I consider scruffy in the extreme, the other my all-time favorite (and which I used to be *very* good with).

I haven't been this impressed with a new (at least to me) write since I discovered Peter Hamilton a few years ago.

recent reading...

Read the latest Janet Evanovich "Stephanie Plum" book two weeks ago titled "Twelve Sharp". Pretty good, but Stephanie's car doesn't get blown up--hey! You gotta stick with your conventions once you establish them. And when's the movie coming out?

and apparently Evanovich wrote some "romance" novels under a pen-name before happening onto Ms Plum and they are getting reprinted now. Not sure if I want to read them, altho they are self-described as "romantic comedies", which might be ok. I think there's a couple of other new ones by JE that I don't have, in her other series. It's about to be xmas vacation time, which means more reading. (Yeah, I know, when do I fit that in between the game-playing).

if you look at JE's website (http://www.evanovich.com/), you can see she has now gone to having fans submit book titles for the Plum series. hmm. And there's another in-between Plum book, like the xmas book a couple of years ago; this one is for Valentine's Day.
