Rated 3 out of 5 by from Different coursr, same issue The problem I had with this course is the same one I've had with several courses; your expectations are rarely satisfied. I understand the difficulty in choosing topics for a survey course such as this, but when you try to be all things to all people, you often end up being very little.

Rated 5 out of 5 by from An Informative Survey of Electrical Engineering I began your course in Electronics and stopped when I needed to subscribe to computer simulation software. I thought I would return to the course when I was ready to work with the simulation software but then discovered this course in Electrical Engineering. When I looked at it I realized I needed to learn about Electrical Engineering before I studied Electronics in depth. This course provided me with the background and depth of knowledge to go back to the Electronics course and begin again to work through it. I enjoyed Professor Bottomley's lectures and benefited from them greatly. For anyone who does not know much about Electrical Engineering, this is an ideal course.

Rated 5 out of 5 by from Very well done. Many things I've wondered about for years, set forth clearly and graciously, and with a nice touch of occasional humor. She is a wondrous lecturer. (I only wish that in the cell phone lecture she had explained how a tiny battery can power a transmission that must go perhaps 30 miles; or, conversely, how the towers are so sensitive as to pick up the tiny signal so sent.)

Rated 4 out of 5 by from Where's the rest? The catalogue says that the course comes with a 408 page course synopsis, glossary and bibliography. I'll be calling The Great Courses to find out where these are. The Guide Book is 185 pages.. No synopsis, glossary or bibliography !

Rated 5 out of 5 by from Informative I found this to be very interesting, especially the information regarding sensors and medical applications. I appreciate that the presenter took time to discuss electronics basics, for which I have no background. This was disappointing as a Wondrium product in that the presenter's background and work surface were so dark. Sometimes I found it difficult to follow what she was demonstrating. A lighter surface and over-the-shoulder views would have helped.

Rated 5 out of 5 by from Electrical Engineering for Everybody Having reviewed the 24 lectures, and would congratulate Professor Laura Bottomley on a comprehensive, well constructed and delivered course (including humour). I highly recommend this course. Thank you Professor Bottomley.

Rated 4 out of 5 by from interesting topic, demos could be better This course covers a broad range of electrical and electronic engineering, topics that few people outside of those majoring in engineering would ever have exposure to. Understanding at a high level how power is generated and transmitted, how a motor works, how cellphones work, etc. can be pretty interesting. The drawback to this course is the quality of the demonstrations which were lower than I expected. To demonstrate how a magnet moving past wires generates a current she shakes a tube with a magnet in it and an external LED; it's impossible to tell if the LED lights up. She has a nail wrapped with wire as an electromagnet to demonstrate how a telegraph works but then just taps a piece of metal onto it; she might as well been tapping it on the table since the magnet plays no part. And so on; many demos miss an opportunity to better understand the effect she is discussing. Overall, though, I thought the course was well worth the time to watch it.

Overview

To many of us, electricity can still seem like the “magic” our ancestors imagined it to be when they saw it in the natural world. But the science of electricity is considerably more amazing than magic, as you’ll see in the 24 fascinating lectures of Electrical Engineering for Everyone. With dozens of live demonstrations, along with explanatory graphics and video, Dr. Laura J. Bottomley brings you on the amazing journey of electrical engineering—the discipline that has taken us from the electric lightbulb to interstellar space to artificial intelligence in less than 150 years.

Radio and Television Transmission

07: Radio and Television Transmission

In the 1880s, Heinrich Hertz proved that the high-frequency phenomena of light and heat are also electromagnetic waves and Nikola Tesla invented the “Tesla coil” which served as the basis for the radio oscillator. Just a few years later, radio signals were being sent and received across the Atlantic Ocean. Examine the additional, fascinating developments that led to the television monitor and then the emergence of digital TV.

Computer Processors and Memory

13: Computer Processors and Memory

Explore the very earliest electronic computers, including Charles Babbage’s Analytical Engine. Although Babbage was not able to completely build it out before his death, his “engine” was based on the same four components that define computers today—input device, some type of memory to store data and temporary calculations, a calculating processor, and an output device.

Computer Networks: Ethernet to Internet

14: Computer Networks: Ethernet to Internet

In the original telephone system, connections were made end to end through switches, and the connection stayed in place until that one conversation was complete. But when email was developed in the 1970s and ‘80s, people weren’t satisfied sending just one type of signal. Explore the development of the ethernet and internet and learn about the protocols that now allow us to send such a wide variety of information types.
