The importance of math and science in the modern world involves navigating your way through traffic, among other qualities. Find out about the importance of math and science in the modern world with help from an expert in computers, with two degrees in both Computer Science and Applied Mathematics, in this free video clip.
Hi, my name's Stefan. Today, I'm going to be speaking on the importance of math and science in the modern world. A great example of how math and science is important is the amount of time it takes for traffic lights to travel from red to green. Let's say we have the intersection here. This is a random intersection. And I'll call this road 1 and this road number 2. First you'll get a collective study of cars, the amount of cars to travel through. How long it takes for this intersection to get clear. And I'll call that t-1, and then you'll look at the cars assembled on this intersection and see how long it takes to get cleared. And we'll call this t-2 and we'll add these numbers together and we'll come up with a cycle. And what you want to do here is you set the cycle to repeat in your computer system to go from red to green. So for example let's say it takes, on average, 30 seconds for this intersection to be clear. And then it takes 40 seconds for this intersection to be clear. Well we know that the cycle is going to be equivalent to 70. And there's a great way that math and science are still used in the modern world.
