Geeking Science: Lightsail in Time

To celebrate today’s announcement (about the Time magazine article) the mission team released a new image from the spacecraft, taken on 28 September 2019. LIGHTSAIL 2 WITH SUN ON THE HORIZON – the Sun peeks over the horizon in this image from LightSail 2 captured on 28 September 2019. The sail appears curved due to the spacecraft’s 185-degree fisheye camera lens. The image has been color corrected and some of the distortion has been removed. (From the 11/21/2019 Kickstarter announcement)

In today’s (11/22/2019) Time Magazine, the LIghtsail was listed in the 100 Best Inventions of 2019.

It’s still up there. Still circling – well, ovaling at this point – the Earth. If you want to follow it, go to the Planetary Society Mission Control. One hundred forty-three days elapsed mission time. Battery charge down to 3.68 volts (from max of 4.2). When I looked this morning, it was a little cool at -5.5 degrees F and about to pass into daylight over the Pacific Ocean.

Geeking Science: The Search for Water

We are bags of mostly water, about 60%, with the brains pushing 75% and lungs over 80%. When humans go into space, the second consideration after air (and air pressure) is water. With air, we face a volume transport problem – but air does compact nicely; though runs toward the explosive during the unpacking. Water, though, is a weight problem and nearly all the hard-to-impossible-to-solve problems with space travel so far have been weight problems.

How does one get off the planet? Fight the weight of gravity. How does one travel through space? Fight the weight of inertia. Every pound in space requires a force to get it off the planet and moving where we will want it to go. Places like the Moon for training and exploration, Mars for first stage colonization testing, and other stars for immigration.

All the best situations for long-term habitation in space are to have water already be there at the end. Yes, we can (and are) studying every manner recycling of water during the journeys. Controlling a dozen gallons per person recycled in a closed system has been challenging. Forward osmosis is just one of the many processes being studied.

But for colonization, where the need for water will be hundreds of gallons per person – not a few dozen – between the requirements for crops and manufacturing and washing and population growth, water must be at the other end. 

We are beginning to find it among the exo-planets. Our tech isn’t *quite* there yet – new cameras and satellites are coming on line to double-check initial findings. But we have some suspects. Each step, each discovery, brings us that much closer to the stars.

Geeking Science: The Aliens Among Us

Why do I love writing about children so much? Because they are the closest to alien thinking we adults experience. Concrete vs. Abstract thinking is such a big gulf.

I love the mene of working with children (babysitting, being a kindergarten teacher, being a parent) is like being an ambassador to beings from another planet and teaching them how to assimilate to our culture.

No, eating fire or dirt is not the best nutrition option on this planet. Sorry, your ambassadorship, but gravity works a bit different here – if you throw something, it will break. Your excellency, I don’t mean to imply anything, but what exactly were you thinking when you did this?

Part of it is everything really is new to them. They are still testing if gravity is consistent everywhere, why are some things good to eat and others not, and what is all this history that happened before they got here that they are expected to understand. Children really need diplomatic attaches to survive in the alien world they’ve been thrust into.

Terrell (in Honestly and Home Cooking Part 1) reacts differently to Mr. Troy’s disability, and very much needs all the adults in his life to keep him together and dressed. Scott (in It’s Dirty and Memory of a Lifetime) is slightly younger than Terrell and goes off the rails a lot more. I don’t think I will ever do a POV inside a child’s head simply because I cannot conceive what they are thinking. 

Things like – a child believes that by staying out of their bedroom, bedtime won’t happen. Because bedtime is associated with the bedroom. Or how my niece K (mentioned in my editing rant this month) didn’t want to write the character having problems because she really couldn’t dissociate herself from the character and she didn’t want to deal with the problems.

The cognitive difference between concrete and abstract thinking is fascinating. I love using fiction to explore it. And I sometimes let the difference in thinking bleed into exploring alien creatures, such as in Grass.

All of the amazement and exasperation in the differences between adults and children especially comes out in classic teen question “What were you thinking?” We expect the adult-sized children to understand cause-and-effect (which they do) and apply it to every situation, especially complicated ones (which they can’t) that we adults know from experience and shared stories is a beyond-dumb idea. They don’t have experience, their friends haven’t survived through the experience to tell the story, and they just don’t think that many steps ahead.

“Look mom, we did think it through. I made sure there was a mattress for when we fall.” “But mattresses have springs. You bounced!” “Mattresses have springs?”

These aliens live among us.

How about you? Are there aspects in children – from baby, through toddler, to teen – which make you geek? Do you have any stories to share?

Geeking Science: Video Game Time Sucks

Astrogarden/Farming Game Image

I call them Inventory Games. You know those games with lots of steps to gather this and that, then build an item, to build another item. The object is not to beat the bad guy but get all the stuff. They appeal to our natural hunt and gather instinct, to have enough to get through the winter. I swear we are hard programmed to play these games, at least I am. Astrogarden takes up far too much of my time, as my 130 level “character” indicates.

Why are these games so addictive? It’s like the manufacturers are tapping directly into our dopamine receptors and drugging us senseless. 

After all, the only thing humans really own is time, and to waste it cutting down virtual trees for hours on end makes no sense.

Originally games were aimed at fulling about 20 to 40 hours, maybe 100 hours of time, complete with a story. Unless it was just mindless Tetris, but even that had natural stop points to sleep and eat and go to work. These Inventory Games NEVER end. They are Grinds. Yet, still, we play.

Sometimes, part of the grind can be short-cut through purchase of items with real-world money. Like you have time to hold down a job while playing these games. This is how the companies make their money. I’ve limited myself to a certain amount per month, treating the “free” Astrogarden as a subscription service. But, really, you can easily drop hundreds of dollars on virtual nothingness. It is worse than Kindle and buying books you never will touch and if your device goes away (or Amazon does, don’t laugh, it has happened for other book and music dealers), everything goes away. I spent weeks getting a new kindle and fixing it just the way I like it when my old one got the black-lines-of-death during the 2019 tax season.

Why, why do I Grind through Inventory Games which provide no meals on my real-world table? One, it is therapeutic. Like doing embroidery and sewing. I notice the more I videogame, the less I sew. They provide the same need, to take a brain break. And the game, with its colored lights, happy music, and noticeable, achievable goals is much more fun, without being really fun, than sewing for 10 hours. Plus I can click my mouse for 10 hours in a single day, and I can’t stab cloth that long without my eyes crossing.

And tons more fun than putting words on a screen. Not reading them after the words successfully fought their way out of my head, but the process of words on screen makes grinding through the trees and rock appealing.

You want to kill the productivity of a nation – get the more active, the more intelligent, the go-getters, and the children – addicted to something that feels like it produces something but actually produces nothing. Kind-of like a paper-pusher job, only with fun lights every five minutes instead of a coffee break every two hours.

I need to figure out how to funnel my “time wasting” habits, the brain breaks, where I am not thinking, back into productive actions like sewing and cleaning house.

In the meantime, I’m off – my Tiger-Cows need milking and my hybrid-crops need harvesting.

Editing Rant: Dark Web Trope

When an Editing Rant gets Short Circuited…

Going through today’s edit.

Oh no, not another “Hacker” tapping into the “Dark Web.” As someone with a bit of background in computers, this always makes me gag. Hacking is not that simple. I mean – ugh. And to have a “dark web” that only a select few know about? Please.

Well, they got to have the remote hacker follow the car chase through the street camera. The whole thing is located in Florida.

I can’t kill it. It’s too integral to the story. Plus it is an accepted trope from the Urban Fantasy genre, that your computer guru guy/gal can do this.

But you know what? I have had enough of this. I am sick to death of this trope. Time to fact check it. Maybe I can make an alternative. I’ve managed to bring a fresh twist to overused tropes before with just a bit of google-fu. I’ll just search on “Florida Street Cams” for giggles. My know-it-all-ness can get smug satisfac….

Holy sweet half-skeletal baby Hel!!!

FL511 – Florida Traffic – https://fl511.com/

Okay, okay. Did not expect to have all those street cams available for anyone to see. You don’t need the friggin’ Dark Web or be a hacker at all.

 But Florida has some really weird privacy rules. North Carolina (where I live) ain’t goin’ to be like that. Right?

Dang-gum Loki’s maternity bra.

This link can connect you with cams from any state! – not all of them everywhere, but the weather cams are a start. If you are hacker collecting them over time for a particular area, I don’t think there will be much of a problem to build up the necessary database to follow a car or person through major streets. – https://www.weatherusa.net/skycamnet/list/North_Carolina

I stand corrected.

Dear author(s) you can have this hacker trope all you want.

I’m going to go into a corner and rock for a while.
