Like the old-fashioned version, it’s a square showing the chemical symbol C, the word “carbon” and the atomic number. But it’s also emblazoned with the image of a diamond (which is of course made of carbon) and also a diagram of the molecule C60, or Buckminsterfullerene, a.k.a. the “buckyball.”
Once she got started, she couldn’t stop. The result, which she finished over winter break this year as a first-year student at Bowdoin College, is a complete and idiosyncratic periodic table of the elements (the original was created 150 years ago this year). Or, as she likes to call it, the periodic graphics of the elements.
Some of the illustrations are quite straightforward: a drawing of the Golden Gate Bridge represents iron; a thermometer is the symbol for mercury; and portraits of Nobel, Fermi, Einstein and Gregor Mendel (creator of the original periodic table) for nobelium, fermium, einsteinium and mendelevium. Others are positively quirky: a cow in a bathtub of milk for calcium; the grill of a retro car for chromium; an avocado and other vegetables for potassium.
One of her personal favorites is gallium, represented by a melting spoon. The reason: gallium is a metal with a melting point of just 85.58° Fahrenheit, so if you use a gallium spoon to stir a hot drink, it disappears before your eyes. She’s also partial to francium. “It has a half-life of just 20 minutes,” she says, so part of the illustration is a clock showing “00:20”—and since it’s named in honor of France, there’s an Eiffel Tower and a chateau as well.
Now that she’s finished, Hu, who intends to major in visual art, environmental science or literature, plans to turn her graphics into notebooks or postcards. “I want to use them to promote knowledge about chemistry to a broad audience,” she says. And she’s building a website where her future projects on science visualization will live. “I want to promote knowledge of chemistry to a broader audience—like teenagers.”
Making chemistry fun seems like a pretty good way to go about it.
