For those of us who struggle to remember even the most basic things taught during our high school science classes, educator and physicist Dominic Walliman has just the solution. His growing YouTube channel “Domain of Science” contains a number of short videos that provide a comprehensive overview of different topics with startling clarity. These teaching tools, designed primarily for the average person, attempt to map out such otherwise complicated subjects as physics, chemistry and mathematics, all within the scope of 10-minute-long animations.
With the help of colorful visuals, charts and lists, each of these “maps” offers a wealth of information not only about the field’s general intellectual history, but also about its various intersecting sub-disciplines. “The Map of Chemistry”, for instance, points out how humans have been relying on chemistry since prehistoric times when fire was invented for cooking and, metals were used to build tools and weapons.
The video then delves into the more fundamental concepts of chemistry, such as the atomic structure and the periodic table. Walliman goes on to explain the four different types of chemical bonds as well as the lesser known Van der Waals intermolecular forces. He also distinguishes between the two basic branches of organic and inorganic chemistry. The map itself is divided into two parts: the green portion deals with the concepts and principles of chemistry, while the yellow section focuses on the different areas and applications of the subject.
If you like Walliman’s approach to chemistry, you should consider purchasing a poster form of the map (available here). The videos, however, leaves certain things unexplained, which is understandable given the sheer amount of information he is working with. The creator states:
I endeavor to be as accurate as possible in my videos, but I am human and definitely don’t know everything, so there are sometimes mistakes. Also, due to the nature of my videos, there are bound to be oversimplifications.
