The small indicators of the huge warnings ..unseen, unnoticed

I take courses from EdX, a conglomeration of MIT, CalTech, Harvard, Stanford, Georgetown, U Ca, amd many other fins schools.

They are free and you may be one of up to 20k students depending on the course.

I take tech.

Their site is HERE

Today I was alerted to several new courses.

Here is one of them.

Principles of Electric Circuits: Part 1

This course provides a solid introduction to the real-world application of electric circuits used in cutting-edge technologies. (In Mandarin with English subtitles).

Prerequisites:

It is necessary to understand the basic ideas of calculus. Knowledge of ODE and electromagnetic fields will help your understanding, but are not necessary conditions for taking the course.

ABOUT THIS COURSE

The principles of electric circuits are critical for electrical engineering and computer science students. In this course, we will cover linear and nonlinear resistive circuits, and dynamic circuits in time and phasor domains. In addition to learning critical methods for analyzing circuits, the course will discuss modern circuit elements, such as MOSFETs and Op Amps, used in cutting-edge technologies. This course provides a solid introduction to the real-world application of electric circuits. You will gain a deeper understanding of the important role circuits play in our lives.

关于本课程

电路原理课程是电类各专业最重要的一门学科基础课，后续各专业基础课和专业课都建立在这门课程的知识体系之上，因此是电类专业本科生的“看家 课”之一。电路原理课程的主要内容包括：线性电阻电路分析、非线性电阻电路分析、动态电路的时域分析和正弦激励下动态电路的稳态分析4大部分。清华大学电 路原理课程的教学包括电路分析基本方法、当代电路元器件、电路原理的实际工程应用等，为学生提供了扎实的基础和丰富的应用。

All knowledge is GOOD. You take it from any source, but that is not the point. Americans who worked in manufacturing, EE, and design shoud get the point here quite clearly. It’s not subtle for any of us. This knowledge is the basis of products. Products are the basis of manufacturing. Manufacturing is the basis of jobs and LARGE GROSS PROFIT. Gross profit is the basis of research, and university endowments.

And here we are.

'Will that be large or extra large, ma'am?'
