Mathematics. World. Randomness.
Brownian motion describes the random movement of particles in fluids, however, this revolutionary model only works when a fluid is static, or at equilibrium. In real-life environments, fluids often contain particles that move by themselves, such as tiny swimming microorganisms. These self-propelled swimmers can cause movement or stirring in the fluid, which drives it away…

Grain… Seed… Born!
Researchers examined stable isotopes from bone collagen and dental enamel to reconstruct the diets of ancient Mongolians. Findings challenge the popular notion of a completely nomadic prehistoric population, linking grain cultivation with the success of the Xiongnu Empire (c. 200 BCE-150 CE) and showing continual grain consumption during the Mongol Empire of the Khans (c.…

Rough.
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that…

Essence over Form…
What clues does our memory use to connect a current situation to a situation from the past? A study conducted by researchers from the University of Geneva (UNIGE), Switzerland, - working in collaboration with CY Cergy Paris University in France - demonstrated that similarities in structure and essence (the heart of a situation) guide our…

Dichotomies…
In a study published in Nature Astronomy, researchers from the United States and Japan unveiled the possible origins of our cosmic neighborhood's "Great Divide". A well-known schism which resulted to have on the one side the "terrestrial" planets, such as Earth and Mars and on the other side the more distant planets such as Jupiter…
