¿Sabes cómo vuelan los aviones, tan pesados y no se caen mientras vuelan? ¿Sabes que viajamos por el espacio sobre el planeta Tierra que se traslada y gira muy rápido y no lo percibimos? ¿O acaso, notas efectos de su movimiento? ¿Cuál es nuestro lugar en el universo? ¿Podemos viajar en el tiempo? ¡Preguntas, muchas preguntas! Con espíritu de descubridores nuestra curiosidad nos motiva a buscar respuestas, a explorar nuestro entorno, a entrar a lo desconocido y hallar nuevo conocimiento.

The 20th century was known as the century of physics. In the past 120 years, concepts such as space, time, energy, entropy and particles were understood to much deeper levels. New paradigms of thinking such as relativity and quantum mechanics emerged. This course is the first course in the Understanding Modern Physics series, which covers an introduction to special relativity, general relativity and cosmology.

"History of Medicine" provides an accessible historical and interdisciplinary perspective on medicine, focused primarily upon therapy and practice, to achieve better understanding of the scope, practice, and limits of medicine. Medicine is defined as the treatment of disease. Human attempts to understand and treat disease will be seen as evolving from the spiritual and mystical practices of the distant past, to the rational approach of the Classical World, and finally to the scientific thinking of the Renaissance and beyond.

Faced with difficult questions people often tend to dismiss and marginalize dissent. Political and moral disagreements can be incredibly polarizing, and sometimes even dangerous. And whether it’s Christian fundamentalism, Islamic extremism, or militant atheism, religious dialogue remains tinted by arrogance, dogma, and ignorance. The world needs more people who are sensitive to reasons both for and against their beliefs, and are willing to consider the possibility that their political, religious and moral beliefs might be mistaken. The world needs more intellectual humility.

Using publicly available data from NASA of actual satellite observations of astronomical x-ray sources, we explore some of the mysteries of the cosmos, including neutron stars, black holes, quasars and supernovae. We will analyze energy spectra and time series data to understand how these incredible objects work. We utilize an imaging tool called DS9 to explore the amazing diversity of astronomical observations that have made x-ray astronomy one of the most active and exciting fields of scientific investigation in the past 50 years.

"Quantum Optics 1, Single photons", allowed learners to be introduced to the basic principles of light quantization, and to the standard formalism of Quantum Optics. All the examples were taken in single photons phenomena, including applications to quantum technologies.

The first MOOC “Photovoltaic solar energy” is a general presentation of the solar photovoltaics technologies in the global energetic context, without extensive details. In particular the description of the solar cell operation is restricted to the ideal case. In contrast this second MOOC allows a deep understanding of the properties of solar cells based on crystalline semiconductors.

This course examines the nature of both science and religion and attempts to explore the possible relationships between them. The primary purpose is to dispel the popular myth that science and religion are entrenched in a never-ending conflict. As a result, this course argues that if the limits of both science and religion are respected, then their relationship can be complementary.
