March 14^{th} or 3.14 is known as Pi Day. Pi is an irrational number and the ratio of the circumference of a circle to its diameter. Almost every job requires people to have knowledge of math. In honor of Pi Day, CareerLocker focuses on occupations where people rely heavily on math to complete job tasks. Occupations include climate change analysts, computer programmers, construction materials estimators, mathematicians, and mathematical statisticians. Many of these occupations are hot occupations and projected to grow by at least 27% over the next 10 years. This adds up to great opportunities!

**Climate Change Analysts**–Climate change analysts study weather patterns to see how and why our modern climate is different from the climate of the past. They spend their time analyzing data and writing papers and speeches. They specifically study atmospheric temperature, ocean conditions, ice masses, and greenhouse gases. They are concerned with determining how these changes impact natural resources, animals, and people. Climate change analysts attempt to create mathematical models of climate change.

**Computer Programmers**–Computer programmers write instructions that tell computers to perform a variety of different tasks.Programmers use computer languages to write programs. They may write programs that will perform accounting or billing functions. Other programs may operate robots or computer-aided design (CAD) machine tool operations. Some programs allow people to create artwork or graphics, while others coordinate space flight operations.

**Construction Material Estimators**— Cost estimators determine the cost of manufacturing products or providing services to prospective customers. They must arrive at costs that meet customer expectations, are lower than their competitors, and are profitable to the organization. They calculate the cost of all the necessary parts, raw materials, and equipment. Estimators arrive at labor costs based on hourly rates and the time they think it will take to produce the product or provide the service desired. They prepare itemized cost estimates and/or present total project costs.

**Mathematicians**–Mathematicians specialize in either theoretical mathematics or applied mathematics. Most mathematicians work in applied mathematics. They solve problems using many different kinds of math and math-related areas. These include computer science, engineering, physics, and business management.

**Mathematical Statisticians—**Statisticians use math to design, interpret, and evaluate the results of experiments, surveys, and opinion polls. They also use math to predict future events. They often apply their mathematical knowledge to specific subject areas, such as economics, human behavior, natural science, or engineering.

**Construction material estimators, mathematicians, and mathematical statisticians are Hot Occupations. Over the next 10 years, job openings in this occupation are projected to increase by at least 27%.**
