Lectures recorded from actual classes are probably a very good for economical reasons, it is one way communication anyway so money or time of professor could be better spent answering questions for example via E-mail. Classes are more useful as you could discuss with others, help each other and ask questions to the teacher provided teacher do not speak to much of the time. > What you don't get is a diploma or a degree.

Have taken courses more less by studying for myself and attend the written exam. In my last exam they had been able to span the course very well in just a few questions, I passed but did not get good grade, this is partly because I had other priorities work full time, fix a few things at my home, spent quite much time on night clubs as I live alone. A written exam you have to take in person, sometimes there is a given task you have to do in group and I guess this might be harder to check as some members could get away with very little effort spent on it. >MIT was one of the first to do this, and still does. > https://ocw.mit.edu/index.htm Think they had or have some kind of cooperation with University there I studied. ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Some colleges and universities offer many online courses for free or very low cost. The online course materials are identical to what's used in the classes at the schools, and lectures are either recorded from actual classes or are the same material the professors present to a class. For some of them the professors will answer questions e-mailed to them. What you don't get is a diploma or a degree. For the free or low cost you get a "Certificate of Completion". If you want a degree or diploma then that costs more and there are specific sets of classes one has to take, but it's still far less costly than attending the classes in person. MIT was one of the first to do this, and still does. https://ocw.mit.edu/index.htm On Sunday, February 16, 2020, 11:23:53 AM MST, N wrote: > > There are plenty and quite many scientific articles available for free on > > Internet.

Re: [Emc-users] Open source CNC architecture - open source complexity OT, more off it
There are plenty and quite many scientific articles available for free on Internet. Universities at least have some check, quite often a written Exam before course could be passed, a little hard to check what kind of books/articles someone have read and even more so what they might have learned. There is a difference between knowing something and passing exams. Who would you trust more? Someone who is self taught and has recent experience or someone who passed the exam 10 years ago and has never touched the subject since? If you need proof of someone's competence then test results are indeed a reasonable indicator, as long as those results are relatively recent. In that case there is nothing stopping the self taught person from taking the tests. Anyone who passes the test has the required knowledge to pass the test, no matter how they learned it. Of course you are relying on the test asking the right questions. Met this attitude then working, "it will all be fine if we just get the project". No, that's just putting your head in the sand and hoping for the best. Quite often try even though I do not think I can do it or good enough. The point is that you try, and in many cases probably succeed. Too many people don't try. It must help to know something about the connection between the stick and the rudders. For the passengers? Not really. It's a big metal tube that flies. That's all they need to know. For motion control using an electric motor it is really good to know the equation of a DC motor. It's not that complex get thing moving but to make it perfect is and require knowledge in mechanics, electronics, mathematics and to some degree software. True if you are building the machine. If you are the operator you don't even have to know what a servo is, let alone the theory of how it works. The required level of knowledge depends on what you want to do. As with any subject, the harder you look the more there is to know. Les ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
