Career description and Mathematics involved:

An astronomer is a scientist in the field of astronomy who studies stars, planets, moons, comets, and galaxies, as well as many other celestial objects. A related but distinct subject, cosmology, is concerned with studying the universe as a whole. An astronomer researches the world beyond Earth.

Mathematics and Astronomy have been closely linked since their respective inception. Isaac Newton discovered the laws of gravity and described the planets' motion in relation to one another. Newton's equations are still used for calculating gravitational forces. As a modern example, astronauts use mathematics to direct a spacecraft that moves at a large speed (approx 17,500 miles per hour) to the International Space Station for a rendezvous. Complex mathematical calculations must be performed so that the two objects moving at high speed can meet at one point without causing damage to each other. Another example may be the use of Radio telescopes to provide information from the unseen electromagnetic spectrum. This includes infrared radiation, X-rays, gamma rays and cosmic radiation. Radio telescopes use complex equations to separate radio frequency “noise” from true deep space signals. This process is known as filtering.

A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish land maps and boundaries for ownership, locations like building corners or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales.

Surveyors used mathematics especially geometry and trigonometry to calculate angles and distances between fixed points. The need to measure areas of irregular surfaces such as fields,

Theoretical Physicist
Career description and Mathematics involved:

A theoretical physicist studies the branch of physics which employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena.

An advanced understanding of all major areas in mathematics is needed for theoretical physics.
