AstroTech: The Science and Technology behind Astronomical Discovery (Coursera)

Modern astronomy has made some astonishing discoveries - how stars burn and how black holes form; galaxies from the edge of the universe and killer rocks right next door; where the elements come from and how the expanding universe is accelerating. But how do we know all that? The truth is that astronomy would be impossible without technology, and every advance in astronomy is really an advance in technology. But the technology by itself is not enough. We have to apply it critically with a knowledge of physics to unlock the secrets of the Universe.

Each week we will cover a different aspect of Astronomical technology, matching each piece of technology to a highlight science result. We will explain how the technology works, how it has allowed us to collect astronomical data, and, with some basic physics, how we interpret the data to make scientific discoveries.
The class will consist of video lectures, weekly quizzes, and discussion forums. Each week there will be five videos, totalling approximately 40 minutes. They will be in a regular pattern - a short introduction, an example science story, an explanation of the key technology area, a look at how the technology is used in practice, and finally a look at what the future may hold.

Syllabus

WEEK 1
Science and Technology
Introducing the themes of the course, and a first look at the science and technology we will study.

WEEK 2
Telescopes and Stars
How telescopes work, how we use them to make images in different colours, and how we use those measurements to understand how stars work.

WEEK 3
Space and Black Holes
Hunting for black holes, and why we need to get above the atmosphere to do it.

WEEK 4
Detectors and the First Galaxies
Detectors, how they work, and how we use them to catch the light from the very first galaxies.

WEEK 5
Computers and Killer Rocks
Why computers are crucial in astronomy, and how they are used to find rare objects.

WEEK 6
Spectroscopy and Dark Energy
How to break up light into its component parts, how that allows us to do astrophysics, and why we believe the Universe is full of a mysterious dark energy.

Journey of the Universe: The Unfolding of Life (Coursera)

Journey of the Universe weaves together the discoveries of the evolutionary sciences together with humanities such as history, philosophy, art, and religion. The course draws on the Emmy-award winning film, Journey of the Universe, and the book from Yale University Press. Journey explores cosmic evolution as a creative process based on connection, interdependence, and emergence. It examines a range of dynamic interactions in the unfolding of galaxies, Earth, life, and human communities. It investigates ways in which we understand evolutionary processes and the implications for humans and our ecological future.

Mechanics: Motion, Forces, Energy and Gravity, from Particles to Planets (Coursera)

Most of the phenomena in the world around you are, at the fundamental level, based on physics, and much of physics is based on mechanics. Mechanics begins by quantifying motion, and then explaining it in terms of forces, energy and momentum. This allows us to analyse the operation of many familiar phenomena around us, but also the mechanics of planets, stars and galaxies.

The Brain and Space (Coursera)

This course is about how the brain creates our sense of spatial location from a variety of sensory and motor sources, and how this spatial sense in turn shapes our cognitive abilities. Knowing where things are is effortless. But “under the hood,” your brain must figure out even the simplest of details about the world around you and your position in it.

Philosophy, Science and Religion: Religion and Science (Coursera) Coursera

Philosophy, Science and Religion: Religion and Science (Coursera)

Philosophy, Science and Religion mark three of the most fundamental modes of thinking about the world and our place in it. Are these modes incompatible? Put another way: is the intellectually responsible thing to do to ‘pick sides’ and identify with one of these approaches at the exclusion of others? Or, are they complementary or mutually supportive? As is typical of questions of such magnitude, the devil is in the details. For example, it is important to work out what is really distinctive about each of these ways of inquiring about the world. In order to gain some clarity here, we’ll be investigating what some of the current leading thinkers in philosophy, science and religion are actually doing.
