Hairstylist Creates Hair Dyeing Masterpieces Inspired by Classic Fine Art Paintings

Street art by SAM3, an artist that paints big as well as small shadows and silhouettes in his urban surroundings. 

“look again at that dot. that’s here. that’s home. that’s us. on it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. 

“the earth is a very small stage in a vast cosmic arena. think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.  

“our posturings, our imagined self importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. our planet is a lonely speck in the great enveloping cosmic dark. in our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves. 

“the earth is the only world known so far to harbour life. there is nowhere else, at least in the near future, to which our species could migrate. visit, yes. settle, not yet. like it or not, for the moment the earth is where we make our stand. 

“there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. to me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.”

First materials woven at atomic and molecular levels: Weaving a new story for COFS and MOFs

An international collaboration led by Berkeley Lab scientists has woven the first 3-D covalent organic frameworks (COFs) from helical organic threads. The woven COFs display significant advantages in structural flexibility, resiliency and reversibility over previous COFs.

There are many different ways to make nanomaterials but weaving, the oldest and most enduring method of making fabrics, has not been one of them – until now. An international collaboration led by scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley, has woven the first three-dimensional covalent organic frameworks (COFs) from helical organic threads. The woven COFs display significant advantages in structural flexibility, resiliency and reversibility over previous COFs – materials that are highly prized for their potential to capture and store carbon dioxide then convert it into valuable chemical products.

“We have taken the art of weaving into the atomic and molecular level, giving us a powerful new way of manipulating matter with incredible precision in order to achieve unique and valuable mechanical properties,” says Omar Yaghi, a chemist who holds joint appointments with Berkeley Lab’s Materials Sciences Division and UC Berkeley’s Chemistry Department, and is the co-director of the Kavli Energy NanoScience Institute (Kavli-ENSI).

“Weaving in chemistry has been long sought after and is unknown in biology,” Yaghi says. “However, we have found a way of weaving organic threads that enables us to design and make complex two- and three-dimensional organic extended structures.”

NDT just murdered B.o.B.

😭

all too well was requested so i decided to try something different.

imagine: all too well as a voicemail.
