NJ Wildberger's Lecture on Infinity in Greek Mathematics and an Australian Website about Engineering

Infinity in Greek mathematics | Math History | NJ Wildberger

A professor, known as NJ Wildberger, published his lectures on the Internet. The description of this particular video is "We discuss primarily the work of Eudoxus and Archimedes, the founders of calculus. Archimedes in particular discovered formulas that are only found in advanced calculus courses, concerning the relations between the volumes and surface areas of a sphere and a circumscribing cylinder. We also discuss his work on the area of a parabolic arc, Heron's formula (improved using ideas of Rational Trigonometry), hydrostatics, and the Principle of the Lever. He was a true genius."


The same professor also has several mathematics playlists. Click on the description of the video to find the links to the playlists. Below are the titles of the playlists available:

About engineering


Here is the introduction on the website, "Traditionally engineers worked across five broad disciplines – chemical, civil, electrical, mechanical and structural. Today there are many more specialized subgroups such as biomedical engineering, aerospace engineering, environmental engineering, agricultural engineering, and software engineering, to name a few. These subgroups are growing and so are the job opportunities for engineers. Engineering is a broad and exciting field with a diverse range of career paths following graduation. We encourage students of all ages to consider and pursue a career in STEM and engineering." The web page serves as a menu to 4 different articles:

  1. Occupational categories -- "Learn about the occupational categories within the engineering profession."

  2. Articulation -- "Engineering articulation is the process of transferring from one occupational category to another."

  3. Statistics -- "Learn why statistics are important for the future of engineering."

  4. Study engineering -- "Discover endless creative possibilities."
