they did with the square root of negative one. They assigned the letter i to the value of square root of negative one. The letter “ i ” represents imaginary. Now, I want to contrast the idea of imaginary with the idea of you cannot see it, because they are different ideas. The square root of negative one is imaginary, because there is no value for that question, but there are many things that you cannot see that are still very much real and true. There is an idea out in our culture that you may or may not have come across yet that says the only things that are true are things that you can sense with your five senses. Part of what I hope to teach you in math is being able to think critically. To show an idea is not true, you can find a counterexample to the claim, just like you did in geometry.

2 There are many examples that contradict the view that the only things that are true are things that you can sense with your five senses. For example each of you have ideas and thoughts that are real. If Jamie, here, is thinking of a pink elephant, she has that thought in her mind that she can see and know in her mind. But if I had a way of looking into her brain, I would not see a pink elephant.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
