Small Things Can Have a Big Impact

The Earth Issue

Small things add up. As you'll read in this issue of fields, that goes for the good as well as the bad.

This spring marks the 50th anniversary of Earth Day. In honor of that semicentennial, we've created a special section in this issue that highlights how high magnetic fields are tackling environmental challenges.

 

These challenges involve very small things, including PFAS (so-called "forever chemicals") and potentially poisonous petroleum molecules found in asphalt roads. Though tiny, these compounds have insinuated themselves far and wide, from the North Pole to your driveway. High-field magnets are shedding light on many other environmental issues, too, including better batteries and solar cells, more efficient conductors, microplastics, fracking fluids, historic climate change and more.

In the face of all these problems, one person can feel powerless. But every small, helpful action adds up, too. Take inspiration from the scientists we interviewed who work hard every day to make the planet better — on their off time. As scientists, they feel a special call to act, and they challenge each of us to step up in whatever ways we can.

So, Happy Earth Day. Whether you’re a scientist at an office, a lab or at heart, we hope these stories spur you to act in ways big and small to help our planet on April 22 — and on every other day of the year.
