I will present the latest understanding of the structure and molecular dynamics of water and ice from the viewpoint of condensed matter physics and based on the state-of-the-art experimental spectroscopic data available. I will discuss the role of short sub-picosecond dynamics in the dielectric response of water and ice from direct current to terahertz. I will demonstrate a recently developed ionic model of water [1] that accounts for its spatial-time heterogeneity and sheds light on its anomalous properties in bulk and at the nanoscale. Finally, I will highlight the possible applications of the fundamental knowledge on water dynamics in energy systems, nanofiltration, and biological sciences.
