Blue sunflower? This is really a mi­cro­scope im­age of liq­uid drop­let res­i­due from water-based chem­i­cals, one-half mil­li­me­ter wide. The drop­lets on the out­er edges are 50 times less wide, and sev­en times less wide than a hu­man hair. This im­age, ti­tled "Blue Sun Flow­er," was cre­at­ed by Devin Brown, sen­ior re­search en­gi­neer at the In­sti­tute for Elec­tron­ics and Nan­otech­nol­ogy at the Geor­gia In­sti­tute of Tech­nol­o­gy. The im­age won grand prize in the 2013 EIPBN (Elec­tron, Ion and Pho­ton Beam Tech­nol­o­gy and Nanofab­ri­ca­tion) mi­cro­graph con­test. (Cred­it: Devin K.
