“I wanna be in Hawaii now,” you’ll whine.
“Sometimes it’s good to wait,” I’ll say. “The anticipation makes it more fun when you get there.”
You’ll just pout.

In the next report I submitted, I suggested that the term “logogram” was a misnomer because it implied that each graph represented a spoken word, when in fact the graphs didn’t correspond to our notion of spoken words at all. I didn’t want to use the term “ideogram” either because of how it had been used in the past; I suggested the term “semagram” instead.
It appeared that a semagram corresponded roughly to a written word in human languages: it was meaningful on its own, and in combination with other semagrams could form endless statements. We couldn’t define it precisely, but then no one had ever satisfactorily defined “word” for human languages either. When it came to sentences in Heptapod B, though, things became much more confusing. The language had no written punctuation: its syntax was indicated in the way the semagrams were combined, and there was no need to indicate the cadence of speech. There was certainly no way to slice out subject-predicate pairings neatly to make sentences. A “sentence” seemed to be whatever number of semagrams a heptapod wanted to join together; the only difference between a sentence and a paragraph, or a page, was size.
When a Heptapod B sentence grew fairly sizable, its visual impact was remarkable. If I wasn’t trying to decipher it, the writing looked like fanciful praying mantids drawn in a cursive style, all clinging to each other to form an Escheresque lattice, each slightly different in its stance. And the biggest sentences had an effect similar to that of psychedelic posters: sometimes eye-watering, sometimes hypnotic.

I remember a picture of you taken at your college graduation. In the photo you’re striking a pose for the camera, mortarboard stylishly tilted on your head, one hand touching your sunglasses, the other hand on your hip, holding open your gown to reveal the tank top and shorts you’re wearing underneath.
I remember your graduation. There will be the distraction of having Nelson and your father and what’s-her-name there all at the same time, but that will be minor. That entire weekend, while you’re introducing me to your classmates and hugging everyone incessantly, I’ll be all but mute with amazement. I can’t believe that you, a grown woman taller than me and beautiful enough to make my heart ache, will be the same girl I used to lift off the ground so you could reach the drinking fountain, the same girl who used to trundle out of my bedroom draped in a dress and hat and four scarves from my closet.
And after graduation, you’ll be heading for a job as a financial analyst. I won’t understand what you do there, I won’t even understand your fascination with money, the preeminence you gave to salary when negotiating job offers. I would prefer it if you’d pursue something without regard for its monetary rewards, but I’ll have no complaints. My own mother could never understand why I couldn’t just be a high school English teacher. You’ll do what makes you happy, and that’ll be all I ask for.

As time went on, the teams at each looking glass began working in earnest on learning heptapod terminology for elementary mathematics and physics. We worked together on presentations, with the linguists focusing on procedure and the physicists focusing on subject matter. The physicists showed us previously devised systems for communicating with aliens, based on mathematics, but those were intended for use over a radio telescope. We reworked them for face-to-face communication.
Our teams were successful with basic arithmetic, but we hit a roadblock with geometry and algebra. We tried using a spherical coordinate system instead of a rectangular one, thinking it might be more natural to the heptapods given their anatomy, but that approach wasn’t any more fruitful. The heptapods didn’t seem to understand what we were getting at.
Likewise, the physics discussions went poorly. Only with the most concrete terms, like the names of the elements, did we have any success; after several attempts at representing the periodic table, the heptapods got the idea. For anything remotely abstract, we might as well have been gibbering. We tried to demonstrate basic physical attributes like mass and acceleration so we could elicit their terms for them, but the heptapods simply responded with requests for clarification. To avoid perceptual problems that might be associated with any particular medium, we tried physical demonstrations as well as line drawings, photos, and animations; none were effective. Days with no progress became weeks, and the physicists were becoming disillusioned.
By contrast, the linguists were having much more success. We made steady progress decoding the grammar of the spoken language, Heptapod A. It didn’t follow the pattern of human languages, as expected, but it was comprehensible so far: free word order, even to the extent that there was no preferred order for the clauses in a conditional statement, in defiance of a human language “universal.” It also appeared that the heptapods had no objection to many levels of center-embedding of clauses, something that quickly defeated humans. Peculiar, but not impenetrable.
Much more interesting were the newly discovered morphological and grammatical processes in Heptapod B that were uniquely two-dimensional. Depending on a semagram’s declension, inflections could be indicated by varying a certain stroke’s curvature, or its thickness, or its manner of undulation; or by varying the relative sizes of two radicals, or their relative distance to another radical, or their orientations; or various other means. These were non-segmental graphemes; they couldn’t be isolated from the rest of a semagram. And despite how such traits behaved in human writing, these had nothing to do with calligraphic style; their meanings were defined according to a consistent and unambiguous grammar.
We regularly asked the heptapods why they had come. Each time, they answered “To see,” or “To observe.” Indeed, sometimes they preferred to watch us silently rather than answer our questions. Perhaps they were scientists, perhaps they were tourists. The State Department instructed us to reveal as little as possible about humanity, in case that information could be used as a bargaining chip in subsequent negotiations. We obliged, though it didn’t require much effort: the heptapods never asked questions about anything. Whether scientists or tourists, they were an awfully incurious bunch.

I remember once when we’ll be driving to the mall to buy some new clothes for you. You’ll be thirteen. One moment you’ll be sprawled in your seat, completely unself-conscious, all child; the next, you’ll toss your hair with a practiced casualness, like a fashion model in training.
You’ll give me some instructions as I’m parking the car. “Okay, Mom, give me one of the credit cards, and we can meet back at the entrance here in two hours.”
I’ll laugh. “Not a chance. All the credit cards stay with me.”
“You’re kidding.” You’ll become the embodiment of exasperation. We’ll get out of the car and I will start walking to the mall entrance. After seeing that I won’t budge on the matter, you’ll quickly reformulate your plans.
“Okay, Mom, okay. You can come with me, just walk a little ways behind me, so it doesn’t look like we’re together. If I see any friends of mine, I’m gonna stop and talk to them, but you just keep walking, okay? I’ll come find you later.”
I’ll stop in my tracks. “Excuse me? I am not the hired help, nor am I some mutant relative for you to be ashamed of.”
“But, Mom, I can’t let anyone see you with me.”
“What are you talking about? I’ve already met your friends; they’ve been to the house.”
“That was different,” you’ll say, incredulous that you have to explain it. “This is shopping.”
“Too bad.”
Then the explosion: “You won’t do the least thing to make me happy! You don’t care about me at all!”
It won’t have been that long since you enjoyed going shopping with me; it will forever astonish me how quickly you grow out of one phase and enter another. Living wi
th you will be like aiming for a moving target; you’ll always be further along than I expect.

I looked at the sentence in Heptapod B that I had just written, using simple pen and paper. Like all the sentences I generated myself, this one looked misshapen, like a heptapod-written sentence that had been smashed with a hammer and then inexpertly taped back together. I had sheets of such inelegant semagrams covering my desk, fluttering occasionally when the oscillating fan swung past.
It was strange trying to learn a language that had no spoken form. Instead of practicing my pronunciation, I had taken to squeezing my eyes shut and trying to paint semagrams on the insides of my eyelids.
There was a knock at the door and before I could answer Gary came in looking jubilant. “Illinois got a repetition in physics.”
“Really? That’s great; when did it happen?”
“It happened a few hours ago; we just had the videoconference. Let me show you what it is.” He started erasing my blackboard.
“Don’t worry, I didn’t need any of that.”
“Good.” He picked up a nub of chalk and drew a diagram:
“Okay, here’s the path a ray of light takes when crossing from air to water. The light ray travels in a straight line until it hits the water; the water has a different index of refraction, so the light changes direction. You’ve heard of this before, right?”
I nodded. “Sure.”
“Now here’s an interesting property about the path the light takes. The path is the fastest possible route between these two points.”
“Come again?”
“Imagine, just for grins, that the ray of light traveled along this path.” He added a dotted line to his diagram:
“This hypothetical path is shorter than the path the light actually takes. But light travels more slowly in water than it does in air, and a greater percentage of this path is underwater. So it would take longer for light to travel along this path than it does along the real path.”
“Okay, I get it.”
“Now imagine if light were to travel along this other path.” He drew a second dotted path:
“This path reduces the percentage that’s underwater, but the total length is larger. It would also take longer for light to travel along this path than along the actual one.”
Gary put down the chalk and gestured at the diagram on the chalkboard with white-tipped fingers. “Any hypothetical path would require more time to traverse than the one actually taken. In other words, the route that the light ray takes is always the fastest possible one. That’s Fermat’s principle of least time.”
“Hmm, interesting. And this is what the heptapods responded to?”
“Exactly. Moorehead gave an animated presentation of Fermat’s principle at the Illinois looking glass, and the heptapods repeated it back. Now he’s trying to get a symbolic description.” He grinned. “Now is that highly neat, or what?”
“It’s neat all right, but how come I haven’t heard of Fermat’s principle before?” I picked up a binder and waved it at him; it was a primer on the physics topics suggested for use in communication with the heptapods. “This thing goes on forever about Planck masses and the spin-flip of atomic hydrogen, and not a word about the refraction of light.”
“We guessed wrong about what’d be most useful for you to know,” Gary said without embarrassment. “In fact, it’s curious that Fermat’s principle was the first breakthrough; even though it’s easy to explain, you need calculus to describe it mathematically. And not ordinary calculus; you need the calculus of variations. We thought that some simple theorem of geometry or algebra would be the breakthrough.”
“Curious indeed. You think the heptapods’ idea of what’s simple doesn’t match ours?”
“Exactly, which is why I’m dying to see what their mathematical description of Fermat’s principle looks like.” He paced as he talked. “If their version of the calculus of variations is simpler to them than their equivalent of algebra, that might explain why we’ve had so much trouble talking about physics; their entire system of mathematics may be topsy-turvy compared to ours.” He pointed to the physics primer. “You can be sure that we’re going to revise that.”
“So can you build from Fermat’s principle to other areas of physics?”
“Probably. There are lots of physical principles just like Fermat’s.”
“What, like Louise’s principle of least closet space? When did physics become so minimalist?”
“Well, the word ‘least’ is misleading. You see, Fermat’s principle of least time is incomplete; in certain situations light follows a path that takes more time than any of the other possibilities. It’s more accurate to say that light always follows an extreme path, either one that minimizes the time taken or one that maximizes it. A minimum and a maximum share certain mathematical properties, so both situations can be described with one equation. So to be precise, Fermat’s principle isn’t a minimal principle; instead it’s what’s known as a ‘variational’ principle.”
“And there are more of these variational principles?”
He nodded. “In all branches of physics. Almost every physical law can be restated as a variational principle. The only difference between these principles is in which attribute is minimized or maximized.” He gestured as if the different branches of physics were arrayed before him on a table. “In optics, where Fermat’s principle applies, time is the attribute that has to be an extreme. In mechanics, it’s a different attribute. In electromagnetism, it’s something else again. But all these principles are similar mathematically.”
“So once you get their mathematical description of Fermat’s principle, you should be able to decode the other ones.”
“God, I hope so. I think this is the wedge that we’ve been looking for, the one that cracks open their formulation of physics. This calls for a celebration.” He stopped his pacing and turned to me. “Hey, Louise, want to go out for dinner? My treat.”
I was mildly surprised. “Sure,” I said.

It’ll be when you first learn to walk that I get daily demonstrations of the asymmetry in our relationship. You’ll be incessantly running off somewhere, and each time you walk into a door frame or scrape your knee, the pain feels like it’s my own. It’ll be like growing an errant limb, an extension of myself whose sensory nerves report pain just fine, but whose motor nerves don’t convey my commands at all. It’s so unfair: I’m going to give birth to an animated voodoo doll of myself. I didn’t see this in the contract when I signed up. Was this part of the deal?
And then there will be the times when I see you laughing. Like the time you’ll be playing with the neighbor’s puppy, poking your hands through the chain-link fence separating our backyards, and you’ll be laughing so hard you’ll start hiccuping. The puppy will run inside the neighbor’s house, and your laughter will gradually subside, letting you catch your breath. Then the puppy will come back to the fence to lick your fingers again, and you’ll shriek and start laughing again. It will be the most wonderful sound I could ever imagine, a sound that makes me feel like a fountain, or a wellspring.
Now if only I can remember that sound the next time your blithe disregard for self-preservation gives me a heart attack.

After the breakthrough with Fermat’s principle, discussions of scientific concepts became more fruitful. It wasn’t as if all of heptapod physics was suddenly rendered transparent, but progress was steady. According to Gary, the heptapods’ formulation of physics was indeed topsy-turvy relative to ours. Physical attributes that humans defined using integral calculus were seen as fundamental by the heptapods. As an example, Gary described an attribute that, in physics jargon, bore the deceptively simple name “action,” which represented “the difference between kinetic and potential energy, integrated over time,” whatever that meant. Calculus for us; elementary to them.
Conversely, to define attributes that humans thought of as fundamental, like v
elocity, the heptapods employed mathematics that were, Gary assured me, “highly weird.” The physicists were ultimately able to prove the equivalence of heptapod mathematics and human mathematics; even though their approaches were almost the reverse of one another, both were systems of describing the same physical universe.
I tried following some of the equations that the physicists were coming up with, but it was no use. I couldn’t really grasp the significance of physical attributes like “action”; I couldn’t, with any confidence, ponder the significance of treating such an attribute as fundamental. Still, I tried to ponder questions formulated in terms more familiar to me: What kind of worldview did the heptapods have, that they would consider Fermat’s principle the simplest explanation of light refraction? What kind of perception made a minimum or maximum readily apparent to them?

Your eyes will be blue like your dad’s, not mud brown like mine. Boys will stare into those eyes the way I did, and do, into your dad’s, surprised and enchanted, as I was and am, to find them in combination with black hair. You will have many suitors.
I remember when you are fifteen, coming home after a weekend at your dad’s, incredulous over the interrogation he’ll have put you through regarding the boy you’re currently dating. You’ll sprawl on the sofa, recounting your dad’s latest breach of common sense: “You know what he said? He said, ‘I know what teenage boys are like.’ ” Roll of the eyes. “Like I don’t?”
“Don’t hold it against him,” I’ll say. “He’s a father; he can’t help it.” Having seen you interact with your friends, I won’t worry much about a boy taking advantage of you; if anything, the opposite will be more likely. I’ll worry about that.
“He wishes I were still a kid. He hasn’t known how to act toward me since I grew breasts.”
“Well, that development was a shock for him. Give him time to recover.”
