Don’t ever stop

This one’s a life update post, but it’s also a “here’s some cool science!” post.

A few days ago, I graduated from Vassar College with a Bachelor of Arts in Cognitive Science and a correlate in Computer Science. I was decorated with general honors, departmental honors, membership to Psi Chi, and membership to Sigma Xi. My time there was awesome.

What’s next?

No lazy summer!

Well, no lazy summer break for me! I’ve already spent three days in my summer lab at NASA Goddard Space Flight Center, where I’ll be working on a number of software development projects. The primary one is a LIDAR-assisted robotic group exploration project, in which we’re going to have a small fleet of robots — a mothership and some workerbots — use 3D LIDAR data to autonomously map and plot paths through an area. This kind of robot fleet could, eventually, be used to explore other planets. One of the big challenges will be dealing with the 3D image data. I’m looking forward to learning more image processing algorithms!

Another project is the redesign of the Greenland Robotic Vehicle, a big autonomous rover that’ll drive across Greenland, collecting a data about snowfall, mapping, and exploring. Did you know there’s ice on that country two miles thick? I may also get to play with a robot that has stereo vision.

You can see some of these robots (and what life in the lab may be like) in this great video about last year’s interns.

So far, I’ve met a bunch of intelligent, friendly folks, started catching up on already-written code, and begun to delve into the platforms, libraries, and algorithms we’ll be using and developing this summer. Our mentors have already proven themselves to be enthusiastic and helpful. Just yesterday, one of them told us,

“You’re engineers at NASA. You want to go where things are, and then go beyond.”

That may end up being our theme for the summer.

A little overwhelming?

There’s going to be so much going on. It’d be easy to get overwhelmed — especially now, jumping in and floundering around in the code, the projects, the people. So much to learn.

But as I sat in the lab today, reading about ROS, going through tutorials, reading about PCL and feature detection in point clouds, digging through last summer’s confusing pile of C# and C++ programs, I realized I wasn’t overwhelmed. And it was because of all the other experiences I’ve had that’ve gotten me to this point.

Confidence. My first URSI summer, flailing through Microsoft Robotics Studio and complicated conceptual theories. Figuring out how to deal with webcams and image data my second URSI summer, reading papers on optical flow and implementing algorithms. Last summer: excavations of an open source flight simulator, the Aeronautics Student Forum, dealing with different work styles and communication styles in my LARSS lab. And more.

I think about all those experiences, and I’m not afraid of this summer. I could almost be overwhelmed — perhaps thinking that everyone else has more of the right kind of experience; I wasn’t trained as a classic engineer — but I know I can succeed. My non-engineering, cognitive science background sets me apart and lets me look at problems a little differently than everyone else. I’m an asset.

I know how to learn. I know how to do research.

I can conquer this summer.

Beautiful and good to eat

Deep down, maybe we all know we are, every one of us, a unique snowflake. But a lot of people, they don’t want it to be true. They want all the snowflakes to melt together into one big puddle. They want to be able to share their subjective view of the world with everyone else. They want to be able to look at a sunset and know that what it’s like for me to see the sunset is the same as what it’s like for you to see the sunset.

Hey, we all want things we can’t have. And in this case, science says no! Here’s a piece of wisdom from David Brin’s sci-fi novel Kiln People:

“We may use similar terms to describe a sunset. Our subjective worlds often correspond, correlate, and map onto each other. That makes cooperation and relationships possible, even complex civilization. Yet a person’s actual sensations and feelings remain forever unique. Because a brain isn’t a computer and neurons aren’t transistors.

It’s why telepathy can’t happen. We are, each of us, singular and forever alien…”

The amazing thing about people is that this fact doesn’t deter us. We keep trying to share our sensations and feelings with each other. As Virginia Woolf writes in her book Orlando:

For it is a curious fact that though human beings have such imperfect means of communication, that they can only say “good to eat” when they mean “beautiful” and the other way about, they will yet endure ridicule and misunderstanding rather than keep any experience to themselves.

To be known and understood

Maybe we’re just stubborn. Maybe we’re clinging to a shred of hope that science is wrong and someday, instead of just overlapping with pieces of each other, we’ll be able to know what it’s like to experience the sunset the way someone else does. Here’s a passage from a favorite book of mine, Man Walks Into a Room by Nicole Krauss:

“When you’re young, you think it’s going to be solved by love. But it never is. Being close—as close as you can get—to another person only makes clear the impassable distance between you. . . .

“But see, the incredible thing about people is that we forgot,” Ray continued. “Time passes and somehow the hope creeps back and sooner or later someone else comes along and we think this is the one. And the whole thing starts all over again. We got through our lives like that, and either we just accept the lesser relationship—it may not be total understanding, but it’s pretty good—or we keep trying for that perfect union, trying and failing, leaving behind us a trail of broken hearts, our own included. In the end, we die as alone as we were born, having struggled to understand others, to make ourselves understood, but having failed in what we once imagined was possible.”

“People really want that, what did you say, merging souls? Total union?” [Samson]

“Yes. Or at least they think they do. Mostly what they want, I think, is to feel known.”

What do you think? Is the ultimate human goal to feel known and understood? And if that’s the case, is the illusion of feeling known enough to compensate for never truly being able to share one’s experiences with anyone else?
