Dark  Matter - “The Tip of an Iceberg of Another World Unrelated to Ours

Answering the observation that the dark matter particle might not be detectable at a colloquium organized by the Kavli Institute for Cosmological Physics at the University of Chicago, Michael Turner, a theoretical cosmologist trained in both particle physics and astrophysics who coined the term “dark energy,” said that for 20 to 30 years, this idea that dark matter is part of a unified theory has been our Holy Grail and has led to the WIMP hypothesis and the belief that the dark matter particle is detectable. “But there’s a new generation of physicists that is saying, ‘Well, there’s an alternative view. Dark matter is actually just the tip of an iceberg of another world that is unrelated to our world. And I cannot even tell you about that world. There are no rules for that other world, at least that we know of yet.

“Ten years ago,” Turner says, “I don’t think you would’ve found astronomers, cosmologists, and particle physicists all agreeing that dark matter was really important. And now, they do. And all of them believe we can solve the problem soon. It’s wonderful listening to particle physicists explain the evidence for dark matter, and vice versa –astronomers explaining WIMPs as dark matter. ”

“As cosmologists,” said Rocky Kolb, who studies the application of elementary-particle physics to the very early Universe, and is the co-author with Michael Turner of The Early Universe, the standard textbook on particle physics and cosmology, “one of our jobs is to understand what the universe is made of. To a good approximation, the galaxies and other structures we see in the universe are made predominantly of dark matter. We have concluded this from a tremendous body of evidence, and now we need to discover what exactly is dark matter. The excitement now is that we are closing in on an answer, and only once in the history of humans will someone discover it. “

“Nothing in cosmology makes sense without dark matter, says Turner. “We needed it to form galaxies, stars and other structures in the Universe. And so it’s absolutely central to cosmology. We also know that none of the particles known to exist can be the dark matter particle. So it has to be a new particle of nature. Remarkably, our most conservative hypothesis right now is that the dark matter is a new form of matter – out there to be discovered and to teach us about particle physics.”

“Dark matter is absolutely central to cosmology, said Turner, “and the evidence for it comes from many different measurements: the amount of deuterium produced in the big bang, the cosmic microwave background, the formation of structure in the Universe, galaxy rotation curves, gravitational lensing, and on and on.”

Precise Images of Buildings That 3D Scanning Enables by Scott Page Design

3D scanning—though it’s been around since the 1960s—has been in the news of late, with Harvard using the technology to recreate ancient statues and MakerBot announcing a desktop scanner last month. But cheaper, faster, and more accessible 3D scanners aren’t just revolutionizing how we print terrifying models of our own faces. They’re also changing how we understand the city.

A fascinating story about urban-scale 3D scanning published on the Atlantic Cities this week explores how a Bay Area architect named Scott Page is using a 3D scanner to generate super-accurate models of historic and dilapidated buildings.

Page’s system takes a series of photographs and patches them together based on how light bounces off each surface. Rather than taking weeks to survey an old building, architects can now generate precise dimensions in just a few hours. Because the scanner uses color photographs, the models are also incredibly beautiful, expressive documents—Page compares them to the first photographs ever made. “There is a magical quality to point cloud imagery, similar to the earliest photos that froze time onto small metallic plates,” he writes on his website.

Eyes of architecture: Staircase spirals

Many of you turned a usually monotonous stairway ascent or descent into fascinating architectural explorations through photos, and here’s a sample of the vertigo-inducing designs captured in stunning shots across the globe. From Antoni Gaudi’s nautilus-shaped steps of La Sagrada Familia, Barcelona, Spain, to the golden spiral inside the Hilton Hotel of Reykjavik, Iceland, these stairwell-centered pictures show visual appreciation for functional swirls found in a variety of buildings worldwide.
