Chemistry Across Scales

Explore in detail how the principles of chemistry apply across the molecular, cellular and Earth systems levels. Learn about the latest research approaches that rely on chemical and other fundamental properties, with a focus on how these can advance understanding and pave the way toward technological solutions to some of the world's most daunting problems.

Core courses

Chemistry Across Scales (Natural Sciences Major)

In their second year, Natural Sciences majors enroll in core courses that provide the foundation for the Natural Sciences concentrations. They also take electives from core courses offered in other majors.

NS110L / Physics of Life

We explore how physics, ranging from mechanics through atomic physics, can be applied to the life sciences. Examples of applications are: fluid flow and heat regulation in biological organisms, electrostatics in the nervous system, and wave phenomena in hearing and vision. The course emphasizes the development of tools and problem-solving approaches needed to describe the physical phenomena at hand.

Prerequisite: CS51 / Formal Analyses

Corequisite:

NS110U / Physics of the Universe

We use gravitational and electromagnetic interactions as representatives for how physics takes experimental evidence and then encodes it into a theoretical framework that can be used to make predictions and draw inferences about new phenomena. The course emphasizes the development of the tools needed to describe the physical structure of nature and then uses these tools to infer the domain of validity of theories in physics and what might lie beyond them.

Prerequisite: CS51 / Formal AnalysesCS111 / Single and Multivariable Calculus

Corequisite:

NS111 / Implications of Earth's Cycles

The Earth system is investigated from its origin to its functioning today. Beginning with the origin of the Universe and the creation of elements in stars, the course progresses to an understanding of solar systems and the conditions that gave rise to habitable planets. Earth evolved from a lifeless, reduced planet with a simple mineralogy to a complex, oxidized planet that can support advanced life such as human beings. An aim of the course is to place human beings in a universal and planetary context, and to see the steps in planetary evolution as an essential perspective on how we relate to Earth today. This course qualifies as part of the Interdisciplinary Minor in Sustainability because it addresses the evolution of Earth and the natural processes regulating the planet. In order to sustainably care for the planet, it is essential to understand the systems and processes operating on Earth from climate regulation to natural resource formation and how human activities impact these processes.

Prerequisite: NS51 / Empirical Analyses

Corequisite:

NS112 / Evolution Across Multiple Scales

“Nothing in biology makes sense, except in the light of evolution” – T. Dobzhansky. From the relationships among species in a forest to the interactions of molecules in a cell, evolution is ultimately responsible. One might be tempted to view Dobzhansky’s quote as indicating that evolution is one key that unlocks the complexity of biology. That view is supported by statements such as “survival of the fittest,” which oversimplify the complexity of evolution. Instead, Evolution at Multiple Scales views evolution as the elaborate set of interconnected concepts it is. Although Darwin published On the Origin of Species over 150 years ago, evolutionary biology continues to be augmented, as new discoveries are driven by new technologies. By evaluating evolutionary concepts in a broad range of biological scenarios, students deepen their understanding of evolution itself, shedding light on the diversity of life it has produced. This course qualifies as part of the Interdisciplinary Minor in Sustainability because it addresses biodiversity. NS112 focuses on the evolutionary processes producing biodiversity, and also addresses the benefits of biodiversity to humans, the consequences of biodiversity loss, and strategies to maintain it.

Prerequisite: NS51 / Empirical Analyses

Corequisite:

NS113 / Chemical Structure and Reactivity

This course explores the physical and chemical properties of nature based on molecular, atomic, and sub-atomic structures, with an emphasis on how structure determines reactivity. Empirical observations will be combined with the principles of chemistry and physics to understand the microscopic properties of nature that underpin phenomena at various scales. Students who complete this course will be able to generate strong mechanistic chemical explanations and apply them in advanced chemistry, physics, earth science, and biology courses.

Concentrations Courses

Chemistry Across Scales (Natural Sciences Major)

In their third year, Natural Sciences majors select a concentration, begin taking courses within it and begin work on their capstone courses. They also take electives chosen from other Minerva courses (other concentration courses in Natural Sciences, core and concentration courses in other colleges). Natural Sciences offers concentrations shown in the table below.

In the fourth year, Natural Sciences majors enroll in additional electives chosen from Minerva’s course offerings within or outside the major. Additionally, they take senior tutorials in the major, and finish their capstone courses.

NS152 / Analyzing Matter and Molecules

Understanding what matter is, how matter and small molecules are studied, and how they can be manipulated is the gateway to technological solutions to many world challenges. Learn principles underlying optics, chemical identification, and chemical separation, and employ analytical tools for molecular and elemental analyses to tackle important interdisciplinary problems. In this course, we explore the application of analytical techniques to a range of topics, from everyday concerns of water quality, to major problems such as oil spill monitoring and cleanup, to ecosystem- and planetary-scale research questions that rely on remote sensing technologies. The first unit focuses on how light and electromagnetic radiation are used to view matter and molecules both directly and indirectly. The second unit focuses on identifying and quantifying molecules based upon their reactions and interactions with other, known chemicals. The third unit focuses on using sub-atomic properties, such as charge or isotopic composition, to characterize analytes. Students explore common techniques to separate and identify specific atoms or molecules within such mixtures. In the final unit we combine approaches from all earlier parts of the course to address current, multi-faceted research questions associated with the Earth’s past, present and future climate. NOTE: In addition to the listed prerequisites, the following courses are recommended prior to taking this course: CS111

NS154 / Life's Chemistry

Investigate biological systems from the cellular and molecular levels of analysis. Learn how the physical and chemical properties of molecular interactions within and between cells give rise to the emergent properties of life. Apply the principles of organic chemistry to understand the reactions that structure and power living systems. Explore key questions about cellular functions of diverse organisms ranging from plants and animals to microbes. Learn about experimental techniques that inform our understanding of cellular function and molecular interactions—including microscopy, x-ray diffraction, stable-isotope probing, enzyme activity assays—and apply them to current research questions.

NS156 / Monitoring and Modeling Earth's Systems

Explore how researchers study and monitor earth systems, including the latest methods for climate, pollution, and ocean monitoring. Delve into how models are used to understand and predict earth systems and how to construct your own models of environmental systems. Use this knowledge to understand the major challenges facing the Earth system, the current state-of-the-science, and to design future solutions. This course will introduce students to the fundamental processes that control weather, air pollution, and climate change and enable them to reduce this complex system to simple, yet useful, models. We will critique current models and remote sensing observations to determine what we can and cannot see or predict. Students will evaluate environmental assessments and forecasts, then extend that knowledge to how science is able to inform and change public policy. We will address what are the most important next steps to solve the pressing environmental challenges facing both science and society.
