Where’s Waldo Goes to Outer Space

There’s a long excerpt from Eureka: Discovering Your Inner Scientist posted at Medium. This is taken from Chapter 4, and discusses pattern-matching games, astronomy, and citizen science:

While such books may seem like merely an amusing diversion for children, the mental process involved in finding Waldo and his friends in Handford’s elaborate drawings is remarkably sophisticated.
There are multiple web sites and academic papers devoted to computer algorithms for locating Waldo within Handford’s drawings, using a variety of software packages, and these are impressively complex, running to hundreds of lines of code and invoking sophisticated image-processing tools. Child’s play, this is not.

The essential element of these books is pattern matching, looking for a particular arrangement of colors and shapes in the midst of a distracting field. There are numerous more “adult” variations on this game, some of them obvious, like the image-based “hidden object” puzzle games Kate sometimes plays for relaxation, or the classic video game Myst. Other classes of games may not seem directly connected, but use the same pattern-finding tricks, such as solitaire card games like Free Cell (my own go-to time-waster) or colored-blob-matching games like the massively popular Candy Crush. In all of these, the key to the game is spotting a useful pattern within a large collection of visual data. This is a task at which human brains excel, and millions of people do it for fun and relaxation.

The unmatched ability of humans to spot meaningful patterns in visual data is the basis for many scientific discoveries, in all sorts of different fields.

Probably no field has benefitted more from pattern-matching than astronomy, though, with many of the field’s most important and unusual discoveries having their origin in the spotting of an odd pattern.

Eureka in APS News

There’s an excerpt from Eureka: discovering Your Inner Scientist in the American Physical Society’s monthly newsletter for December. This takes off from Ernest Rutherford’s (in)famous line deviding science between physics and stamp collecting:

Like a lot of kids, I had a stamp collection for a while. I never collected anything particularly notable, but going through old letters and boxes of stamps from relatives who had had collections was enjoyable in a quiet way. And putting the individual stamps together to make a larger picture was fascinating. I remember an intimidatingly large three-ring binder with spots for every US stamp that had been issued to that point, and the satisfaction of completing a page. My hobby also gave a sense of history outside the collection — for example, seeing all the stamps of the 1893 Columbian Issue commemorating the 400th anniversary of Christopher Columbus’ famous voyages showed me there was a good deal more to the story than I had heard in grade school.

Beyond the immediate pleasures of building a collection, though, the impulse to collect can be a starting point for science. The most obvious product of collecting hobbies is an array of physical objects, but collecting is also a mental state. Serious collectors develop habits of mind particular to their hobbies — a sort of constant low-level awareness of possible sources of stamps, an ability to spot new specimens, and close observation and knowledge of the fine gradations that separate valuable stamps from worthless bits of colored paper. These habits of mind also serve well in science; the simple act of collecting a diverse array of interesting objects or observations also serves as the starting point for most sciences.

This is drawn from Chapter 1, and the same basic argument is presented in this video:

Eureka at the Big Idea

An essay for John Scalzi’s Big Idea series:

It seems very appropriate to be writing about the new book in a feature called “The Big Idea,” because I can say without hyperbole that it’s a book about the biggest idea in the history of humanity.

OK, maybe there’s a trace of hyperbole there, but just a little. Eureka is about an idea that is radically transformative on every level from individuals to the entire human species. It’s not an Internet technology, or a particular fact, but a process:

You look at the world around you,

You think about why it might work the way it does,

You test your theory with experiments and further observations, and

You tell everyone you know the results.

This four-step process is the essential core of all of science. More than that, it’s central to just about everything we do. Science leads directly to all the technologies that have allowed a not especially threatening species of hairless plains apes to thoroughly dominate the surface of the planet (for good or ill). More than that, science is central to activities that we do just for fun.

Eureka Excerpt at the Science of Us

New York Magazine’s blog The Science of Us has an excerpt from the Introduction of Eureka: Discovering Your Inner Scientist, Scientists Are Not That Smart:

The popular image of scientists is of a tiny, elite (and possibly deranged) minority of people engaged in esoteric pursuits. One of the three most common responses when I tell somebody I’m a physicist is, “You must be really smart. I could never do that.” (The other responses are, “I hated that when I took it in high school/college,” and, “Can you explain string theory to me?” This goes a long way toward explaining why physicists have a reputation as lousy conversationalists.)

While the idea that scientists are uniquely smart and capable is flattering to the vanity of nerds like me, it’s a compliment with an edge. There’s a distracting effect to being called “really smart” in this sense — it sets scientists off as people who think in a way that’s qualitatively different from “normal” people. We’re set off even from other highly educated academics — my faculty colleagues in arts, literature, and social science don’t hear that same “You must be really smart” despite the fact that they’ve generally spent at least as much time acquiring academic credentials as I have. The sort of scholarship they do is seen as just an extension of normal activities, whereas science is seen as alien and incomprehensible.

Even in the twenty-first century the popular image of a scientist is a reclusive genius in a lab coat, mixing formulas or working out equations inaccessible to all but the initiated few. The idea that scientists are somehow smarter than the rest of us is a common, yet dangerous, misconception, getting us off the hook for not knowing—or caring—how the world works. How did science become so divorced from our everyday experience? Is scientific understanding so far out of reach for the non-scientists among us?

As science popularizer Chad Orzel argues in Eureka, even the people who are most forthright about hating science are doing science, often without even knowing it. Orzel shows that science isn’t something alien and inscrutable beyond the capabilities of ordinary people, it’s central to the human experience. Every human can think like a scientist, and regularly does so in the course of everyday activities. The disconnect between this reality and most people’s perception is mostly due to the common misconception that science is a body of (boring, abstract, often mathematical) facts. In truth, science is best thought of as a process: Looking at the world, Thinking about what makes it work, Testing your mental model by comparing it to reality, and Telling others about your results. The facts that we too often think of as the whole of science are merely the product of this scientific process. Eureka shows that this process is one we all regularly use, and something that everybody can do.

By revealing the connection between the everyday activities that people do—solving crossword puzzles, playing sports, or even watching mystery shows on television—and the processes used to make great scientific discoveries, Orzel shows that if we recognize the process of doing science as something familiar, we will be better able to appreciate scientific discoveries, and use scientific facts and thinking to help address the problems that affect us all.

People Saying Nice Things About It:

“This fun, diverse, and accessible look at how science works will convert even the biggest science phobe.” —Publishers Weekly (starred review)

“Similar to Richard Rhodes or Dava Sobel, Orzel makes complicated scientific narratives accessible to lay readers.” —Library Journal

“In writing that is welcoming but not overly bouncy, persuasive in a careful way but also enticing, Orzel reveals the ‘process of looking at the world, figuring out how things work, testing that knowledge, and sharing it with others.’” —Kirkus Reviews

“I know, I know, you think you’re just not smart enough to be a scientist. Chad Orzel might convince you otherwise with Eureka. Drawing on basketball, stamp collecting, Angry Birds, Iron Chef, and Antiques Roadshow among his many colorful examples, he ably demonstrates that science is not a rarefied alien endeavor performed solely by those with genius IQs. It’s a process, and a way of thinking about the world available to all. Surprise! You’re probably committing acts of science every day.”—Jennifer Ouellette, author of The Calculus Diaries and Me, Myself and Why

“Chad Orzel is absolutely right: everyone has a scientist inside them, eager to burst out and look at the world in a new way. This book provides great examples that will inspire you to let your inner scientist free.”—Sean Carroll, theoretical physicist at Caltech and author of The Particle at the End of the Universe

“Many people are curious about the natural world, but few consider themselves scientists. Using an engaging array of examples of scientific discovery—some recent, others drawn from history—Chad Orzel takes readers on a wonderful tour of how scientists think.”—David Kaiser, Germeshausen Professor of the History of Science, MIT and author of How the Hippies Saved Physics: Science, Counterculture, and the Quantum Revival

“Chad Orzel’s previous two books were just fine and dandy. However, this one is awesome. If anyone wants an insight into nature and the process of science, this is the book to get. Chad uses his witty writing style along with historical stories to show that science is part of our human nature.
Do you have a non-scientist friend? They will love this book. Or maybe your friend is a scientist—yup, it’s for scientists too.”—Rhett Allain, Professor of Physics at Southeastern Louisiana University and author of WIRED Magazine’s Dot Physics

How to Teach Relativity to Your Dog

Published by Basic Books, 2012.

Cover Copy

Physics professor Chad Orzel and his inquisitive canine companion, Emmy, tackle the concepts of general relativity in this irresistible introduction to Einstein’s physics. Through armchair —and sometimes passenger-seat —conversations with Emmy about the relative speeds of dog and cat motion or the logistics of squirrel-chasing, Orzel translates complex Einsteinian ideas — the slowing of time for a moving observer, the shrinking of moving objects, the effects of gravity on light and time, black holes, the Big Bang, and of course, E=mc2 —into examples simple enough for a dog to understand.

A lively romp through one of the great theories of modern physics, How to Teach Relativity to Your Dog will teach you everything you ever wanted to know about space, time, and anything else you might have slept through in high school physics class.
