“These three images are snapshots of a spark-ignited expanding flame in different environments of the same hydrogen-air mixture. The top flame shows the ideal, reference case of a stable, smooth flame surface in a quiescent environment at atmospheric pressure. The middle flame is taken under elevated pressure simulating that within an internal combustion engine. The bottom flame is taken in a highly turbulent environment simulating another aspect of the engine interior. All images were taken at 8000 frames per second, using schlieren photography. The radius of the top flame is 11.4 millimeters.” C.K. Law, Swetaprovo Chaudhuri, and Fujia Wu (Princeton University).
Theories of Everything by Dayna Thacker
Thacker on her work:
John Muir wrote, “When we try to pick out anything by itself we find that it is bound fast by a thousand invisible cords that cannot be broken, to everything in the universe.”
This body of work takes inspiration from the “thousand invisible cords” of modern string theory, ancient Islamic sacred geometry, and the principles of ecology. These complex areas of study have several overlapping concerns: the harmony of relationships; the correlation between the very large and infinitely small; symmetry; repetition; beauty; an appreciation for the elegance of a perfectly balanced system; and the extreme interconnection of everything.
Kupalo festival (also Kupailo, Ivan Kupalo). A Slavic celebration of ancient pagan origin marking the end of the summer solstice and the beginning of the harvest (midsummer). In the western Ukrainian Lemko region and Prešov region it was called Sobitka. In Christian times, the church tried to suppress the tradition, substituting it with the feast day of the Nativity of Saint John the Baptist (24 June), but it remained firmly part of folk ritual as the festival of Ivan (John, from Saint John) Kupalo.
