Heidi Arjes wearing one of her resistor beanies .

Heads up: There’s a new protest hat in township and it’s a must-have for science lovers.

After pussyhats became the go-to protest accessory at the Women’s Marches in January, scientists were inspired to create their own symbolic beanies to wear to the March for Science on April 22 in D.C. and hundreds of other cities worldwide.

The beanies have a very geeky “resistor” design. They symbolically feature a battery, three resistors in a series, and a closed circuit stimulated with white yarn. Resistors are used in electronics “to slow down the current from information sources such as a battery” and avoid the items from violating, the Stanford University microbiologist behind the design said in an online video.

And instead of pink, thehats will be green and blue to honor our good age-old planet Earth.

Not simply is the design, created by Heidi Arjes, familiar to scientists, but it packs a powerful political message.

“The symbol for three resistors in a series, as any person whose taken physics knows, would increase the opposition, ” Arjes explained in the video. How appropriate for a protest, right !?

With the hopes of stimulating her beanies as inclusive to the science community as is practicable, the talented knitter made several other designs, such as ones that represent a DNA double-helix, laboratory glassware, renewable energy, computers, and a heartbeat EKG.

And for those who live in areas that will be too hot to rep a beanie during late April, she’s likewise made resistor knit headbands and armbands.

Arjes will be marching at a rallying in San Fransisco, but with more than425 other processions around the world, she’s encouraging others to make their own hats as well.

To further spread the spunky science-wear tendency, Arje’s knitting blog Craftimismpartnered with Project Thinking Cap to encourage knitters, crocheters, and sewers around the world to join in and mail over hats for distribution at the D.C. march.
