“I think the most amazing fact I learned was that they have a part of the brain that we don’t have—a part that we can’t even identify. This suggests that they sense, understand, and even feel more than we do. It still blows me away to think about it.”—Gabriela Cowperthwaite, Director of Blackfish
baby's first words
- baby: d-d-da..
- father: daddy?
- baby: dada /ˈdɑːdɑː/ or Dadaism was an art movement of the European avant-garde in the early 20th century. Many claim Dada began in Zurich, Switzerland in 1916, spreading to Berlin shortly thereafter but the height of New York Dada was the year before, in 1915. To quote Dona Budd's The Language of Art Knowledge,
- Dada was born out of negative reaction to the horrors of World War I. This international movement was begun by a group of artists and poets associated with the Cabaret Voltaire in Zurich. Dada rejected reason and logic, prizing nonsense, irrationality and intuition. The origin of the name Dada is unclear; some believe that it is a nonsensical word. Others maintain that it originates from the Romanian artists Tristan Tzara's and Marcel Janco's frequent use of the words "da, da," meaning "yes, yes" in the Romanian language. Another theory says that the name "Dada" came during a meeting of the group when a paper knife stuck into a French-German dictionary happened to point to 'dada', a French word for 'hobbyhorse'.
- The movement primarily involved visual arts, literature, poetry, art manifestoes, art theory, theatre, and graphic design, and concentrated its anti-war politics through a rejection of the prevailing standards in art through anti-art cultural works. In addition to being anti-war, Dada was also anti-bourgeois and had political affinities with the radical left.
W Magazine and Tim Walker adventure to Burma
It is a four-hour train ride from Yangon, the former capital of Burma, followed by an arduous hour-long climb in a retrofitted dump truck, to Golden Rock, a 25-foot-high naturally formed granite boulder so impossibly perched on the edge of a mountain that the only logical explanation for its precarious existence is the Buddhist one. According to lore, a single strand of hair holds the hallowed rock, which is devotionally covered in layers of gold leaf, in place. For Tim Walker, a photographer known for his monumental fantasy-world sets, Burma was the ultimate stage for a shoot. “When they first saw the pictures, people asked if we had built the backgrounds,” he says. “But, in fact, they were beyond anything I could have even imagined.”
You are looking at the most precise gravity map ever made of a distant galaxy cluster. Using the map, astronomers have determined that the cluster is roughly 650,000 light-years across and contains enough matter to make 160 trillion suns.

The cluster, known as MCS J0416.1–2403, is located about 4 billion light-years away and consists of hundreds of galaxies all orbiting one another. Newton’s gravitational equations can tell you the mass of two objects orbiting one another, provided you already know the mass of one of them. However, because these galaxies are all so distant, there is no way for scientists to determine any of their individual masses.
But there is another way. Einstein’s theory of general relativity tells us that heavy objects warp the fabric of space-time around them. As light travels through these warped regions it will become distorted, and we see that as smeared out rings and arcs in our telescopes, an effect known as gravitational lensing. Using the Hubble space telescope, astronomers identified smudges in the light seen around MCS J0416.1–2403. These distortions are images of even more distant galaxies sitting behind the cluster; their light has been lensed by its enormous mass. By carefully determining just how much the light is smeared out, researchers can calculate the amount of matter sitting within the galaxy cluster.
The 160 trillion solar masses includes both visible matter and dark matter, which gives off no light but makes up the bulk of the cluster’s mass. By studying the dynamics of all the galaxies within the cluster, astronomers can better understand this mysterious substance. Researchers will also continue mapping the smeared out images to increase the precision of their mass calculations, learning about the cluster’s finer details to figure out its history and evolution.
