Remember MIT Open Courseware? It’s the program to put all of the MIT curriculum online so you can learn mechanical engineering or whatever you want for free. Well, there’s something else you should be aware of, because some of you might find the MIT offerings a bit too much to start with. If that’s the case, try Khan Academy.
One of the problems we run into on The Kneeslider, is many posts delve into topics that demand a bit of technical knowledge. How many times have we made a reference to torque, for instance, when off we go in the comments with statements showing some folks could use a refresher, or even an introduction, to what torque is and how it’s measured.
As electric motorcycles are added to the mix, you need to know something of chemistry and electricity, and any motorcycle is an entire physics demonstration in itself. Dealing with any of these topics requires math, you can only talk in generalities so long before you need a bit of geometry and even basic algebra to illustrate what you’re saying and others need knowledge of the same subjects to know if you’re making any sense.
So how can Khan Academy help? According to Salman Khan, the originator of the site, “The Khan Academy is a not-for-profit organization with the mission of providing a high quality education to anyone, anywhere.” OK, but what actually is it? It’s over 1400 videos on subjects ranging from basic arithmetic to advanced algebra, linear algebra, geometry, trig, calculus, physics and lots, lots more. Each video is a bite sized piece where Khan walks you through the topic for maybe 5 or 10 minutes. It is very, very good. Whether you have zero background in any of the topics or just want to brush up, these videos are worth the time.
With all of this free technical training available online, all of the excuses fade away. If you want to learn, there it is. If you’re using a computer to read this, you have everything you need. Of course, the motivation is up to you.
