Electrical engineers are involved in electric power generation and distribution, as well as in the development of personal devices such as smartphones and computers. They also work on the design and development of electric power systems for buildings and cities, and play a crucial role in connecting society through wireless communication networks.
The work of electrical engineers often involves designing and building wireless and telecommunications networks, such as the internet, cellular networks, and satellite systems. They are responsible for developing technologies that enable the transmission and reception of digital and analog data, including voice and video signals, over long distances using optical fibers, wireless radio waves, and copper cables. Electrical engineers are also involved in signal processing, which deals with the analysis and manipulation of signals. These signals can be analog, involving continuous variations, or digital, where the signal varies according to discrete values.
Electrical engineers also contribute to the development of algorithms and techniques for signal analysis and manipulation, ensuring effective data transmission, speech recognition, image processing, and medical imaging. They design control systems that govern the operation of machines, electronic systems, and devices. By utilizing information from sensors and mathematical algorithms, electrical engineers fine-tune the operations of these systems.
Electrical engineering is closely related to computer science, with some overlap in the skills required and the courses offered in degree programs. However, electrical engineering specifically focuses on building solutions using electrical components, while computer science involves developing theoretical solutions with logic and computation. Electrical engineers may work on circuit design, solid-state circuits, and computer-aided design, contributing to the development of powerful computers and electronic devices.

This is an algorithm that students can quickly learn to apply to new problems and implement in different ways.
Mathematics is a fundamental intellectual tool in computing, and many universities offer joint programs in computer science and mathematics. For instance, the Massachusetts Institute of Technology offers a Bachelor of Science in Computer Science and Molecular Biology and a Bachelor of Science in Computation and Cognition.
Additionally, computer scientists require strong mathematical knowledge and skills to succeed in their careers. Mathematics helps develop the capacity for abstract reasoning, critical thought, and logical deduction, which are essential for computer science. A strong background in mathematics also enables computer scientists to work with calculus, probability and statistics, and number theory, which are crucial in cryptography, data science, simulations, game development, and machine learning models.
Overall, computer science has roots in mathematics, and a solid understanding of mathematics is necessary for a successful career in computer science.
