The time-consuming, paper-based animation techniques of Disney’s golden years are a thing of the past. Today, most animators use computer programs to render the worlds of movies and TV shows. Often, young animators get into the field armed with a background in computer science and an affinity for art. Many animators also emphasize the advantage of mastering multiple types of computer platforms and software.
4. Fashion Designer
Clothes of different cuts, sizes, and fabrics don’t just magically drape themselves on the human body. To create the initial pattern, a designer must craft a 3-D garment on 2-D fabric, which requires a knowledge of geometry. Of course, the garment has to fit the model in all the right places and be scaled up appropriately for different sizes, which means it also involves algebra and arithmetic. And in order to make a profit, the designer has to calculate the cost of the fabric and labor, then determine how much he or she should charge for a piece of clothing.
5. Park Ranger
Custodians of our national parks don’t have to be as frustrated as Ranger Smith, constantly arguing with Yogi Bear. Their work is made easier by strong backgrounds in forestry and conservation, and an intimate knowledge of the delicate ecosystems they work to protect. Employing their knowledge of botany and biology, they are sometimes called upon to help fight forest fires or take care of injured animals in the park.
Back in the days of the explorers, cartographers made maps using sundials, compasses, and telescopes, pinpointing and drawing out different locations with all the information available to them (which, in the early days of mapmaking, wasn’t very much). Today, cartographers use aerial imagery and digital databases to make maps, sometimes indicating three dimensions on paper or a screen. Even though computers now help with many calculations, cartographers need to know algebra, calculus, trigonometry, geology, and statistics.
When a carpenter starts to make a set of stairs, how does she determine how many to make? With math, of course! Carpenters use geometry to determine the dimensions for what they build, as well as during the building process. No one likes a slanted set of stairs!
Although zookeepers have the awesome privilege of hanging out with exotic animals like lions and elephants, most of their time is spent caring for these creatures. Much like a veterinarian tends to a cat or dog, zookeepers care for the physical and mental wellbeing of the animals. They achieve this through careful observation and by using their training in biology and life science to treat any illnesses the animals may have.
9. Ship Captain
Even in these days of high-speed travel, the seas are filled with ships, many of them delivering cargo from one side of the world to another. When setting the course, a ship captain must make some sophisticated calculations, taking into account a vessel’s position, wind speed, current, tide, and cargo weight. The advent of GPS has aided this somewhat, but captains must still be able to use older technologies like maritime charts in case computers fail at sea. In addition to a knowledge of physics and computer science, a captain has to know how to work all the machinery on board, and will often be asked to log the ship’s pollution.
Scuba divers have some great job perks, like interacting with incredible wildlife and seeing the world in a new way. But they couldn’t do so safely without an intimate knowledge of math and physics. For even the simplest plunges, divers need to calculate the rate at which they should rise to the surface to avoid decompression sickness. They also need to know the laws of physics to determine how long their oxygen tanks will last given the water pressure at various depths.
