This course is part 1 of the specialization Advanced Spacecraft Dynamics and Control. It is a direct continuation of the Coursera specialization Spacecraft Dynamics and Control. This first course focuses on nonlinear attitude feedback control using a range of angular momentum devices. The course provides a comprehensive review of prerequisite material. Next it develops equations of motion of a spacecraft with momentum exchange devices such as reaction wheels (RWs), control momentum gyroscopes (CMGs) and variable speed control moment gyroscopes (VSCMGs). The course discusses developing a complex spacecraft simulation with a number VSCMGs and how to approach debugging such complex software. The use of the work/energy theorem is discussed to assist with debugging the simulation by validating angular momentum, energy, changes in momentum and mechanical power. Further, the use of null motion is explored to reconfigure the attitude control devices to avoid singularities and gimbal lock. The redundancy is exploited to seek control solutions that avoid classical CMG singularities.

Mechanics is one the most important subject in physics. You will learn many concepts and key points under mechanics title those will also be used in other subjects of physics. Mechanics can be defined as the behavior of the particle under any effects. It can be studied under main two topics which are kinematics concerning the motion of the particle and dynamics concerning the causes of motion. Kinematics is one of the two branches of mechanics. It deals with the motion of particles not the causes of the motion. Motion in one dimension in other words linear motion and projectile motion are the subtitles of kinematics they are also called as 1D and 2D kinematics. Dynamics deal with the causes of motion. What makes objects move is our primary concern. Moreover, we give Newton’s law of motion and try to explain causes of motion with these laws. Let’s begin with concepts one by one that will help us in analyzing motion. In this 1-hour long project-based course, you will be able to- analyze the variables that affect Force as a function, compute newtons second law of motion, Compute the motion of block on an inclined plane, Compute torque, analyze the variables that affect momentum of a body and calculate centripetal acceleration of a body on a circular path.

Learn the mathematics behind the Fibonacci numbers, the golden ratio, and how they are related. These topics are not usually taught in a typical math curriculum, yet contain many fascinating results that are still accessible to an advanced high school student. The course culminates in an explanation of why the Fibonacci numbers appear unexpectedly in nature, such as the number of spirals in the head of a sunflower.

Understanding renewable energy technologies is important, but equally important is knowing how to effectively deploy these technologies to provide renewable energy to end-users – the topic of this course. Upon completion of the course, you will understand the development and management of renewable energy projects, large and small, from conception to launch and subsequent operation. This course will teach you to plan, execute, and operate renewable energy projects such as solar PV plants, wind farms, and geothermal generators. We first describe how to develop a renewable energy feasibility study and make go-no-go project decisions. We then examine project site selection and evaluation of renewable technology alternatives and technology vendors. Next, we review methods for financing and organizing renewable energy projects. The course concludes with an examinations of project construction, operations and maintenance, repowering, and plant decommissioning. These capabilities will round out your understanding of renewable energy uses and deployment – come join us! Note that this course is the third in a four-course Coursera specialization in Renewable Energy: 1. Renewable Energy Technology Fundamentals 2. Renewable Power Systems 3. Renewable Energy Projects 4. Renewable Energy Futures

Chemical biology is a burgeoning field that has rapidly risen to prominence. This surge of interest has been fuelled by chemical biology’s applicability to understanding critical processes in live cells or model organisms in real time. This success has arisen because chemical biology straddles a nexus between chemistry, biology, and physics. Thus, chemical biology can harness rapid chemistry to observe or perturb biological processes, that are in turn reported using physical assays, all in an otherwise unperturbed living entity. Although its boundaries are endless, the multidisciplinary nature of chemical biology can make the field seem daunting; we beg to differ! Here, we deconstruct chemical biology into its core components, and repackage the material. In the process we build up for each student a practical and theoretical knowledge bank that will set these students on their way to understanding and designing their own chemical biology experiments. We will discuss fluorescence as a general language used to read out biological phenomena as diverse as protein localization, membrane tension, surface phenomena, and enzyme activity. We will proceed to discuss protein labeling strategies and fusion protein design. Then we will discuss larger and larger scale chemical biology mechanism and screening efforts. Highlights include a large amount of new data, tailored in the lab videos, and a large number of skilled presenters.
