    Sorry if I came off harsh and ignorant with my defense of HappyDad. I should have been more tactful and the words I used were uncalled for. Respect to you...

    Doctor Who ...

    Thank you. But what you responded was not needed, but again, thank you.

    In re-reading what I said, it was more harsh than what I was actually trying to convey.

    Maybe we both can help others here to be more respectful even when we have different viewpoints of matters.

    Peace my friend.

    I was first introduced to algebra during the final few weeks of Primary School, and remember approaching the subject with a distinctive lack of enthusiasm!

    However, it was very much a case of just having to come to grips with the matter, particularly when deciding to learn the electrical trade. Take for example Ohm's Law, E = I.R. which is arguably the most fundamental calculation for electrical circuits.

    Once you encounter three-phase systems, it starts getting more involved; to calculate the power in a three-phase circuit the formula is P=√3.V.I.CosՓ

    Then, if ever involved with Electrical Test Work, it gets more involved again; an example being Wenner's Equation for calculating soil resistivity (a project our team is embarking on next week)


    I have been engaged in Electrical Testing since 1980, and can vouch for the fact that this field of the electrical trade calls for both the use of algebra, and a readiness to get ones "hands dirty".

    A good example of that is the project that I have just come back from, which was testing the protection relays at a manganese mine in northern Australia. At that site, everything is liberally coated in a sticky black dust from off the manganese ore. Not the sort of job you front up to in a white shirt, tie and three-piece suit!

    If I had even thought of posting something similar to what you posted I would have been afraid of getting remarks that I was arrogant.

    Bless you my friend. But I do have to admit, I had to look at that calculation several times before I would even try to begin to solve it. But today we have Excel. I wonder how many people in the world today could do a square root on paper as I was taught to do "back in the day (late 70's)."? .. lol

    I know very little about electrical theory or electrical engineering. But I can't begin to imagine the number of supporting notes, references and documents that Wenner must have used to arrive with his formula.

    Peace.

    I did poorly at math in grade school. My first run at college I majored in English because I knew I couldn't cut it in the STEM classes. Nine years after I graduated college I went back to study something that people would pay me to do. A year later I had a certificate in business managment with an emphasis in accounting. I spent the next tweny-six years of my life doing Algebra every day. Somewhere along the line I got good at it. I suspect that most people on this thread actually use algebra at lot more than they think.

    Our college finance system (at least here in the US) is more f****D up that our medical insurance. It's a device for turning the future income of students into the current income of college profs and staff. The loan program makes no distinction between majoring in brain surgery and Lithuanian Art History. So we send people into the world with no job skills and $100k in debt and wonder why they are struggling.

    High school algebra was ok, once you realized that whatever you do to one side of the equation, you must do to the other. Hated the word problems though. But loved geometry. Got 97% on my high school final. We had an excellent teacher, Dr. Saul, who would painstakingly make sure everyone understood the proofs for the propositions before he went on. Great teacher model.

    I did not enjoy algebra until I was being educated in Electronics.

    Even to troubleshoot the little conveniences we have around us, supposing we aren't just going to throw them away, algebra is useful. In my previous work (re-furbishing phones) I was able to fix some built-in power supply problems because the caps were not rated with a sufficient voltage margin and would stop functioning. Yes, I use algebra.
