projection chamber (TPC) and the transition radiation detector (TRD). A schematic of the ALICE detector is shown in Fig.1a. The material composition of the three subdetectors is diverse. The detailed knowledge of the detector geometry and composition50,52(see the Supplemental Material of ref.48...
Motivated by the phenomenology in the condensed-matter flat-band Dirac systems, we here construct a holographic model that imprints the symmetry breaking pattern of a rather simple Dirac fermion model at zero chemical potential. In the bulk we explicitly include the backreaction to the corresponding...
When you bend forward, your center of mass is located below your bent belly in a place where there is no mass at all. Weird to think about, but that's the average position of all your mass. Many objects' center of mass are outside their bodies. Think of doughnuts or boomerangs. ...
This book explains many of the most entertaining aspects of the physical world and its principles, including optical illusions, light tricks and mirages, watermelon “bombs” of force, gravity and flight, travel to the moon as Jules Verne predicted, brain teasers, heat, boomerangs, “perpetual ...
In comparison, the coldest recorded place on Earth’s surface is Vostok, Antarctica at 183 K (–89ºC), and the coldest place (outside the lab) known in the universe is the Boomerang Nebula, with a temperature of 1 K. Figure 6. Each increment on this logarithmic scale indicates an ...
Make a boomerang. Tell how lift is created with your boomerang. Here is a YouTube video with directions for an origami boomerang. Get permission before going to YouTube. Lesson 39 Level 1-4 (Materials: balloon, straw, fishing line or strong thread or something similar) Take a straw and...
volume. Picture something shaped like a giant boomerang in space with big pods on the ends. The reason to dothatis that the spacecraft could use its maneuvering gyros to flip its body around to avoid incoming missiles and such – which would then pass through the empty center of the space...
However, it led to the development of many other studies, such as the balloon-borne Boomerang and Maxima experiments, which sought to obtain more information about the higher-frequency content so as to map the CMB sky with greater angular resolution. Then, starting in 2003, a team of ...
Oh? So it's not true, as they suggest, that finding the same features in both the maps of WMAP and of BOOMERanG’s excludes that instrumental noise can account for the result? Well, it does show that the general shape isn't due to the instrument noise. The difficulty is that...
