SIMPLE DOES NOT EXIST. “Because helium does not form molecules, understanding the microscopic mechanisms underpinning its transition from an insulator to a warm dense metal should be more straightforward. Helium therefore constitutes an excellent testbed for advanced numerical and theoretical methods for warm dense low-Z system physics. Unfortunately, large discrepancies still exist between the scarce existing experimental data and state-of-the-art simulation results.” https://lnkd.in/dtAti2a View in LinkedIn

PHASE CHANGES. “There has been significant progress recently toward a better understanding of the insulator-to-metal transition in dense fluid hydrogen.However, the relationship of the molecular dissociation to the metalization and ionization processes must be described before we can understand the roles of density and temperature in that transition.” https://lnkd.in/dtAti2a View in LinkedIn

THE SIMPLEST UNKNOWNS. “In the wake of the tremendous amount of data collected by NASA's Juno and Cassini probes at Jupiter and Saturn, the need increases for accurate models of the physical and chemical properties of gas-giant constituents such as hydrogen isotopes, helium, and their mixtures.” https://lnkd.in/dtAti2a View in LinkedIn

POLYPLOID FERNS. “Three different cytotypes, diploid, triploid, and tetraploid, occur within the fern species Polypodium vivginianum or rock polypody.” https://lnkd.in/dthseww View in LinkedIn

Called dandylion after dent de lion, teeth of the lion, which describes the shape of the leaves. View in LinkedIn

THE CODE. “What is the algorithm running on the laptop of the Universe? If such an algorithm exists, I would argue that it should be a simple one defined on the discrete spacetime lattice. The complexity and richness of the Universe come from the enormous memory size and CPU power of the laptop, but the algorithm itself could be simple." https://lnkd.in/dZi_jmp View in LinkedIn
