A cosine wave emerges from Euler's Formula. Music, no narration. Animated with d3.js. Created by Willy McAllister.

Euler's formula relates the complex exponential to the cosine and sine functions. This formula is the most important tool in AC analysis. It is why electrical engineers need to understand complex numbers. Created by Willy McAllister.

The course applies molecular biology and reverse genetics approaches to the study of apoptosis, or programmed cell death (PCD), in Drosophila cells. RNA interference (RNAi), or double stranded RNA-mediated gene silencing, will be used to inhibit expression of candidate apoptosis-related genes in cultured Drosophila cells. Teams of 2 or 3 students will design and carry out experiments to address questions about the genes involved in the regulation and execution of PCD in this system. Some projects involve the use of DNA damaging agents or other cytotoxic chemicals or drugs to help understand the pathways that control a cell's decision to undergo apoptosis. Instruction and practice in written and oral communication are provided.

The Experimental Project Lab in the Department of Aeronautics and Astronautics is a two-semester course sequence: 16.621 Experimental Projects I (this course) and 16.622 Experimental Projects II. This site offers material on 16.621. In the course, two-person teams initiate a project of their own conception and design in 16.621 and then complete it in 16.622. For many students, this is a first encounter with research standards and techniques. It is a complicated course that requires a lot of interaction and support and also access to facilities and materials, but it is rewarding for students to explore an hypothesis under the guidance of a faculty advisor.
This OCW site presents the building block materials of the course, which can provide only a profile of the course because the most important learning elements are the interactions between student team, faculty, project advisor, and shop staff and also between student team members. However, this site offers some of the preparation and guidance materials for students embarking on an experimental project. To emphasize the focus on communication skills, a set of study materials and examples of student work are provided.

The Experimental Project Lab in the Department of Aeronautics and Astronautics is a two-semester course sequence: 16.621 Experimental Projects I and 16.622 Experimental Projects II (this course). Students in 16.622 gain practical insight and improved understanding of engineering experimentation through design and execution of "project" experiments. Building upon work in course 16.621, students construct and test equipment, make systematic experimental measurements of phenomena, analyze data, and compare theoretical predictions with results. Deliverables comprise a written final project report and formal oral presentations. Instructions on oral presentations and multi-section reporting are given. Experimental Projects I and II provide a valuable link between theory (16.621) and practice (16.622).

Explore the global history of nuclear reactors from 1951 to 2022. This visualization showcases 626 operational reactors, highlighting the dominance of pressurized light water reactors (PWRs). Different reactor types exhibit geographic patterns, with retired reactors and ongoing upgrades observed in various countries. The average age of reactors in the United States was 41 years in 2021.

In 2020, 437 new solar electricity projects worldwide added a total capacity of 38,941 MW. The largest project was the 1348 MW Karapınar YEKA-1 solar farm in Turkey. Asia, North America, and Europe were the main contributors to solar capacity, with China leading with 23% of the global additions.

Student teams formulate and complete space/earth/ocean exploration-based design projects with weekly milestones. This course introduces core engineering themes, principles, and modes of thinking, and includes exercises in written and oral communication and team building. Specialized learning modules enable teams to focus on the knowledge required to complete their projects, such as machine elements, electronics, design process, visualization and communication. Examples of projects include surveying a lake for millfoil from a remote controlled aircraft, then sending out robotic harvesters to clear the invasive growth; and exploration to search for the evidence of life on a moon of Jupiter, with scientists participating through teleoperation and supervisory control of robots.

Short Description:
In sheet metal, you work with a wide array of different metals, including steel, aluminum, copper, and brass. Identifying and selecting the right metal for the job is an essential skill for a sheet metal worker. This book covers different styles of metals, how to identify them, and the different ways they can be used.

These astronauts aren't just cool because they took a trip of a lifetime, they also hold some famous firsts in history.

Feedback is the design technique where a part of the amplifier output "feeds back" to the input of the amplifier. The overall effect creates a very stable gain determined by resistor ratios. Created by Willy McAllister.

This course will teach fundamentals of control design and analysis using state-space methods. This includes both the practical and theoretical aspects of the topic. By the end of the course, you should be able to design controllers using state-space methods and evaluate whether these controllers are robust to some types of modeling errors and nonlinearities. You will learn to:

Design controllers using state-space methods and analyze using classical tools.
Understand impact of implementation issues (nonlinearity, delay).
Indicate the robustness of your control design.
Linearize a nonlinear system, and analyze stability.

This course introduces the basic driving forces for electric current, fluid flow, and mass transport, plus their application to a variety of biological systems. Basic mathematical and engineering tools will be introduced, in the context of biology and physiology. Various electrokinetic phenomena are also considered as an example of coupled nature of chemical-electro-mechanical driving forces. Applications include transport in biological tissues and across membranes, manipulation of cells and biomolecules, and microfluidics.
