"Synthetic Biology and Materials Science Part 1: Biological Manufacturing We've discussed some aspects of biotechnology already but we have yet to discuss the promising field of synthetic biology. We are now able to manipulate biological organisms in ways that have technological applications and one of the most important of these applications has to do with materials science. We are now beginning to figure out how to engineer microorganisms that will manufacture important materials for us which circumvents traditional chemical manufacturing via petrochemicals.

Most systems are multi-star systems with binary systems being extremely common. These are systems where two stars orbit around their center of mass and some of them even have planets. But we also know that stars come in so many varieties due to their differing masses and they leave behind different remnants. For this reason there are a great many possible combinations of star types that produce different kinds of binary systems. What happens when you"

"Complex Numbers: Operations Complex Conjugates and the Linear Factorization Theorem In getting through algebra we never talked about complex numbers but they are important so let's discuss them now These are numbers with a real component and an imaginary component so we first have to understand what i means in a mathematical context. It's the square root of negative one. Then we need to learn how to do arithmetic with these expressions and finally we can understand how we get answers in this form when using the quadratic formula but with a negative discriminant. Much to discuss check this out"

"Calculating the Area of Shapes We know about all kinds of one-dimensional parameters like side lengths and what not but now we want to talk about the two-dimensional area that a shape will occupy. This can be thought of as the amount of surface that a shape covers. In this clip we go over some of the formulas we can use to calculate the area for different shapes and how these are derived.
