Today’s post is brought to you by fiber optic cable, the innovation currently being inserted into my lawn.

In a discussion about grass vs. clover lawns today, I mentioned that our neighborhood is being wired for fiber internet. For weeks, we’ve had orange-vested dudes (and they’re all dudes) roaming in packs, hauling giant spools of multi-colored cables, digging up driveways and yards (and reseeding with industrial-strength grass seed), and generally doing their best to drag our 1990s development into the modern era.

Now we’ve got cable ends sticking up everywhere, a new panel in the grass looking like a secret bunker entrance, and neighbors wondering whether all this fuss is worth it. 

It also led to the question, how do fiber optics work, exactly?

Answer: I have a layman’s understanding of the technology (data becomes light and zoom zooms down a shiny glass tube) but yeah, better look that up:)

Here’s a quick backgrounder about fiber optics from the folks who invented it.

Educational Resources | Optical Fiber | Optical Communications | Corning

Corning scientists Dr. Robert Maurer, Dr. Peter Schultz, and Dr. Donald Keck invented the first low-loss optical fiber in 1970. Inspired by their belief that information could be transmitted through light, Drs. Maurer, Schultz, and Keck spent four years experimenting with different properties of glass until they succeeded, creating the first low-loss optical fiber for telecommunications use.

How does it work?

Encoded into a pattern of light waves, information travels through each optical fiber by a process of internal reflection. The waves move through the fiber from a given source to a destination such as a cable box where it is then decoded.

(So is it a little like a super sophisticated version of an Aldis signal lamp? I guess that’s one way to think about it.)

And just for fun, how do they connect North America to Africa to Asia, and everywhere else?

If we do find aliens someday, I hope they are carbon-based and heck, while I’m wishing, mammals. Why? Because I want to try their food.

On some days I think that food is as close to a universal language as we’ve got. This is hardly an original thought, but the millions of cookbooks and posts and discussions on food and its importance only serve to make my point.

Food is good stuff. It supports us, sure, but it also helps define us as individuals and as social animals. What did you have for lunch today? How did you get your ingredients? How did you cook it? Did you share it?

Many folks’ introduction to other cultures happens over a meal. I grew up in a small town that was relatively isolated in terms of culture. Meat by the loin, heaping helpings of potatoes, sweet corn, one overcooked and somewhat suspect green at the edge of the plate. That sort of thing. I still have a soft spot in my tastebuds for pork and sauerkraut, but by and large the food was straightforward, hardly adventurous.

My parents took care of that.

Facing down a future with nothing more radical than chicken and waffles (yes, my poutine-loving Canadian friends, it’s a thing and you’d adore it:), the parental units got their hands on books like The New York Times Large Type Cookbook and Mrs. Chiang’s Szechwan Cookbook (both of which I still have on my shelf) and went to work. My palate and my social perspective are better for it.

An article on NPR talks about a group of Hungarian foodies fighting anti-immigrant prejudice with dinner. What a brilliant idea. Eritrean sourdough pancake bread, Somali fried bananas, or Afghan pie with fresh Syrian cream cheese? Sign me up, and while I’m there introduce me to the people too.

Think about your day, and the role food played in it. Did you go out to the barn to harvest eggs? Or did you open the refrigerator? What would breakfast look like (yours or mine) if the international shipping industry shut down?*

Food is a big deal, and sharing it is sharing part of who you are. It’s why we invite people over for dinner instead of going out, It’s why Italy, of all places, has made significant progress in gluten-free food awareness as a way to make sure that gluten intolerance doesn’t get in the way of social communion.

Honestly, I’ve always felt that one major flaw in much speculative fiction revolves around food. Let’s see, fantasy = stew plus berries and mead, science fiction = rations that sound a lot like the worst protein bar you’ve every had or meals in a pill.** That’s not entirely fair but it’s not all that far off, either. It’s also not, from my food-oriented point of view, all that realistic.*** Sure, humans can put up with a lot when we must. Conflict, migration, that first year away from home, all times of upheaval, culinary and otherwise. But people still remember their traditions.

What we really want is that moment when life returns to normal, and among other things “normal” means real food. Whether your definition of “real” means Thanksgiving dinner or a Ramadan feast or congee, we use food as a touchstone. Lose that, and we lose an important piece of ourselves. (That doesn’t mean we can’t change, as my childhood diet attests, but it’s not like I’m eating hydrolyzed protein three meals a day either. Things got better. And hey, I feel the urge to add yet another footnote!****)

I’ve always been a bit shy but I learned early that one surefire way to start a conversation is to ask someone what they eat.

So if aliens arrive and invite us to the table, I’ll bring a fork.

** For future reference, fellow SF Canada writer Krista D. Ball has a highly detailed and useful book on realism in fantasy food (just how long does it take to make stew and how in blazes do I carry leftovers?): What Kings Ate and Wizards Drank.

*** For a fascinating look at the intersection of food and space exploration, check out NASA’s Food for Spaceflight or read the section on food (titled “Discomfort Food, When Veterinarians Make Dinner, and Other Tales of Woe from Aerospace Test Kitchens”) in Mary Roach’s excellent Packing for Mars.

**** A good example of this is our family’s holiday smorgasbord: a few years ago we made the shift from Grandma Johnson’s handwritten recipes (so homey!) for dishes like Swedish meatballs and limpa and roast pork to the spectacular versions of same in Marcus Samuelsson’s Aquavit. Yes, an Ethiopian-born immigrant throws down on traditional Swedish food and wins big. See what I mean? The food still says home, only better:)
