Isotope effects are widely used in infrared analyses of a range of chemical systems. Water molecules with three active modes are one of the most studied for testing the applicability of theoretical models. Whereas the IR spectrum of free gaseous water is very complex due to the accompanying rotational spectral features, the ATR-FTIR spectrum of a…

Hands-on experiments with overturning some prisms (partially filled with water) lead students to a conjecture which can be confirmed by using a 3D geometry programme and reinterpreting the process of "overturning of a prism" in an appropriate way. But such confirmations are not a proof and particularly cannot answer the question…

Water is one of the most common molecules in the universe. Water is polarized, but it has many states besides the normal tetrahedron depicted in standard biology texts. Water is also the most ubiquitous molecule on Earth, the universal solvent. It is the internal and external habitat of cells. Ecologically, water is contiguous with life and the…

This article illustrates the potential for hackathons to serve as an innovative educational tool in addressing the underrepresentation of minority communities in science, technology, engineering, and mathematics (STEM) fields. Using Merced, California--a region recognised for its agricultural economy, socioeconomic disparities, and diverse…

This new report documents 10 years of Space to Grow, celebrating this dynamic program's significant impact on Chicago schools, neighborhoods and the environment. From transforming schoolyards into vibrant, multifunctional spaces that foster learning, play, connection to nature, and community engagement, to helping mitigate flooding, Space to Grow…

Addressing food, energy, and water issues through a systems approach is essential for Native American communities, where climate change, natural disasters, and pandemics further strain access to these vital resources. Tribal communities experience a disproportionate impact from these global crises, which heightens and exposes existing…

Mathematical modeling involves using mathematics to represent, analyze, and make predictions or decisions about real- world situations. Garfunkel and Montgomery (2016) elaborate on six components of the mathematical modeling process, including identifying the problem, making assumptions and identifying variables, doing the math, analyzing and…
