Kaća Bradonjić received her B.S. in philosophy and physics from Northeastern University and her Ph.D. in physics from Boston University.

 

Situated at the intersection of physics and philosophy, Kaća’s research is focused on foundational questions of the physical interpretation of the mathematical formulations of gauge theories of gravity, and particularly on the role of conformal and projective structures. 

Kaća’s artistic work explores the use of metaphor as means of understanding the relations among physical, intellectual, and emotional spaces. A project of note is Projections, a series of paintings based on impressions of academic talks.

Prior to coming to Hampshire College, she taught at Wellesley College and Boston University. More details about her work can be found at www.kacabradonjic.com.

Recent and Upcoming Courses

  • Physics I covers the fundamental principles and methods of physics by teaching classical mechanics, while emphasizing its limits and sketching out how they are modified in quantum physics. The topics will include the essence of measurement, data collection and analysis, the basic models (point particle, plane wave, harmonic oscillator, etc.), mechanics (motion and its causes), and fundamental interactions. Special focus will be given to general principles, such as the conservation laws. Students will approach these topics in an active-learning style, wherein hands-on lab activities are integrated with problem-solving sessions and mini-lectures. The course aims itself at all who seek an understanding of the fundamental laws of physics, including students on pre-professional track and students who focus on physical or mathematical sciences. Readings and written work will be assigned for each class.

  • Modern physics encompasses the major discoveries made in the early 20th century, which can be broadly divided isnto relativity and quantum mechanics. This course is a survey introduction to the special theory of relativity, the development of quantum theories of matter, light, and their interactions, and the application of these theories to atomic, nuclear, and solid state physics. The topics covered will include special-relativistic mechanics, the atomic structure of matter, black body radiation, photo-electric effect, particle-wave duality, Schrodinger equation in one and three dimensions, and electron spin. The course is essential for students intending to pursue advanced physics courses on these topics and would be of interest to science students who want to gain a basic understanding of the foundations of modern physics.

  • What is energy? This course will cover the concept of energy in the contexts of theoretical and applied physics. Starting with the idea of energy as a way to explain the interactions of elementary particles in fundamental physics, we will then explore the role of energy in physical processes on larger length scales. Our trajectory will take us from the interactions of matter and light described by quantum physics, which govern biological and chemical processes, to interactions of macroscopic objects and thermodynamic systems, which are relevant to our daily lives and are described by classical physics. This theoretical basis will allow us to discuss a variety of mechanisms of energy generation, conversion, transfer, storage, and use efficiency in various practical contexts. Key Words: Physics, Energy, Environment

  • Nature seems abundant in symmetry, manifesting not only in spatial symmetries of living beings, but also in visual art, music, and even social interactions (do to others as you would.). In an intuitive, hands-on approach this course will introduce and develop the key ideas of group theory, a branch of mathematics used for the study of symmetry. It will cover the core definitions (subgroups, quotient groups, cosets, isomorphisms, and homomorphisms), and a detailed study of certain types of groups (finite groups, cyclic groups, permutation groups, and abelian groups). Interweaving theory and application, we will understand the value of group theory in the fields of chemistry, physics, and biology, as well as its place in music and art. The course is suited both to students with concentrations in math and physical sciences, and to those who want to understand symmetry and its applications in an accessible, yet formal way. Key words: math, symmetry, science

  • What are space and time? This course will follow the evolution of the scientific understanding of these concepts which are so fundamental to our experience of the world and of ourselves. Our journey will trace the intellectual paths of physicists who grappled with these questions, including Newton and Einstein, taking us from the conceptions of space and time familiar from our daily experiences to the modern understanding of four-dimensional spacetime as described by the special theory of relativity. Occasionally we will look for insights from philosophers and for inspiration from writers and artist. Since mathematics is the language of physics, we will use basic high school algebra and graphs. No prior exposure to physics is necessary. This course is best suited for students so fascinated with the ideas of space and time that they are willing to grapple with abstract concepts and sometimes tedious algebra in order to gain a basic, but genuine understanding of special relativity. Keywords: physics, space, time, relativity

  • This course develops the basic geometric, algebraic, and computational foundations of vector spaces and matrices and applies them to a wide range of problems and models. In addition to containing real finite dimensional vector spaces, linear independence, linear transformations and inner product spaces, the course will cover eigenvalues and eigenvectors, diagonalization, and linear programming theory with applications to graph theory, game theory, differential equations, Markov chains, and least squares approximation. Basic programming will be taught and used throughout the course. Readings and written work will be assigned for each class. Keywords: math, linear algebra
