Course Overview

Matter is the raw material of the universe. Stars, planets, mountains, oceans, and atmospheres are all made of matter. So are plants and animals—including humans and every material thing we have ever produced. Amazingly, this immense variety is generated by a limited number of chemical elements that combine in simple, well-defined ways.

Consider carbon, a relatively common atom with many faces:

    Diamond: When one carbon atom bonds to four others in a cubic structure, repeated many times, the result is diamond, a form of pure carbon that is the hardest known mineral.

    Graphite: In a different geometric arrangement, carbon atoms bond in a flat lattice that is among the softest known substances, graphite, which is used in pencil leads and lubricants.

    Nanotubes: Loop a sheet of graphite, one atom thick, into a cylindrical shape and you get a carbon nanotube, a material 300 times stronger than steel with remarkable electrical properties.

    Life: You would not be reading this if carbon were not an atom of surprising versatility, able to combine with other elements to create the complex chemicals that are the basis of life.

And carbon is just one element among roughly 100 that are the basic, indivisible constituents of all normal matter. They are the ingredients of our universe, and the science of chemistry tells us how elements combine and why the resulting compounds have the properties they do.

This physical picture of the world has taken centuries to assemble, but its insights are now available to anyone. No scientific background is needed to appreciate such miracles of everyday life as the bounce of a rubber ball or water’s astonishing power to dissolve. Moreover, the study of matter has led directly to such inventions as semiconductor circuits for computers, new fabrics for clothes, and powerful adhesives for medicine and industry. These discoveries were hard-won by scientific sleuths, but we can all sit back and enjoy the details—just as we delight in the solution to a good detective story.

The Nature of Matter: Understanding the Physical World deciphers the mystery of matter in 24 engaging and enlightening half-hour lectures that are geared toward anyone with a curious mind; there are no other prerequisites. Your guide is Professor David W. Ball of Cleveland State University, a noted researcher, textbook author, and award-winning teacher, who has a gift for making chemistry beautifully accessible and engaging.

How the World Works

Starting with the fundamental components of the universe—matter, energy, and entropy—you quickly build your conceptual toolkit to include atoms and the different ways they bond to each other, forming molecules and other compounds. Plentiful graphics and animations help make these ideas crystal clear, launching you into the crucial mission of chemistry: explaining how matter behaves. In The Nature of Matter, you investigate the principles behind a fascinating array of substances, including some very familiar products:

    Teflon: Discovered by accident, this long chain of molecules, called a polymer, is chemically unreactive and very slippery, giving it a multitude of uses—from non-stick coatings to leak-proof tape for pipe fittings.

    Cotton textiles: Cotton towels and clothes are absorbent and comfortable because cotton fibers act as tiny capillaries, wicking away moisture by a phenomenon known as adhesion.

    Soap: If oil and water don’t mix, then why does soapy water remove oil? The reason is the long hydrocarbon chain of a soap molecule, which is attracted to water at one end and oil at the other.

    Gasoline: Liquid gasoline doesn’t burn easily, contrary to many movie explosions—but gasoline vapor does. It evaporates at a relatively low temperature, making it an ideal fuel for internal combustion engines.

You’ll discover that chemistry is a truly practical science, for after hearing the many examples that Professor Ball presents, you’ll be able to make informed decisions in such areas as nutrition, dental care, and recycling. This knowledge is even relevant to issues in the news like environmental pollution and climate change.

Delve Deep into Matter

Professor Ball takes you deep into the details of his field, explaining how to read the periodic table of the elements (which he calls “the most important, one-page tool in all of science”), why the electron shells in an atom are like a house, and the differences between a compound, a solution, a composite, and other arrangements of matter. Armed with this background, you’ll find that a number of life’s ordinary enigmas suddenly make sense:

    Why does salt melt ice? In the lecture on solutions, you learn how particles of salt (the solute) interfere with the formation of crystals in water ice, giving it a lower freezing point and causing it to melt.

    How do you tell a vitamin from a mineral? Vitamin and mineral nutrients illustrate an important division in chemistry: vitamins are typically covalent compounds, while minerals are usually ionic compounds.

    Is car wax necessary? Water beads rather than pools on a waxed car, inhibiting the formation of rust. In chemical terms, the adhesion between water and wax is much lower than the cohesion within bulk water.

    How do lizards climb up walls? Solved only recently, this mystery involves tiny hairs on the lizard’s toes, which stick to the wall through intermolecular forces, a phenomenon that has inspired new adhesives.

      You’ll also study some extraordinary enigmas, such as superconductivity, which is the flow of electricity with zero resistance. Long thought to be achievable only at temperatures close to absolute zero, this phenomenon has been observed at higher temperatures in certain ceramics and other materials, raising the possibility of power transmission with perfect efficiency.

      Why Matter Matters

      Since prehistoric times, knowledge of materials has driven the development of civilization. The Stone Age was succeeded by the Bronze Age, the Iron Age, the industrial age, and now the age of silicon—the element that is the basis of the semiconductor revolution.

      What’s next? Professor Ball devotes his final lecture to future trends in the science of matter. Speculation about the future often feels unreal. But after absorbing the previous 23 lectures of The Nature of Matter, you will know enough to form your own opinions. Is nanotechnology around the corner? Will 3-D printing take off in spectacular new directions? Can we adapt the secrets of spider silk, barnacle glue, and other remarkable biomaterials for our own uses?

      It all depends on how we manipulate the raw materials of the world. Professor Ball notes that the “fun part about being a chemist is that we still have lots of combinations of these raw materials to explore.” And the joy of this course is learning from an outstanding teacher who is part of this exciting quest.

Rated 5 out of 5 by from Taught an old dog some new tricks First, I am a materials engineer so I have something of a grasp on the topic. FYI: Materials Science is a discipline that lay between physical chemistry and physics. Our good lecturer comes at this topic from the chemistry side but isn't limited to just that. For me, he presented many refreshing and new perspectives on materials. He had a knack for saying things just the right way to allow me to gain some new insight into this broad topic. I found the prof to be easy to understand and easy to listen to. You won't have to be schooled in materials to enjoy his presentations.

Rated 4 out of 5 by from Very Worthwhile! Although its title may be interpreted to refer to particle physics, this offering actually deals almost exclusively with chemistry. Indeed, Professor David Ball presents an interesting chemistry course that goes way beyond what is covered in high school. He not only discusses abstract issues such as the structure of atoms and covalent and ionic bonds but discusses at length actual substances such as food, fuels and explosives, air and semiconductors. The course is very well structured and neither too elementary nor too specialized. However, minor shortcomings must be pointed out: • no doubt to be more accessible to the US public, Professor Ball uses feet, pounds and Fahrenheit degrees while occasionally referring to SI units what generates an unnecessary and potentially confusing mishmash; • there are some annoying repetitions from one lecture to another though, thank goodness, no contradictions. Overall, this interesting course is highly advisable to all.

Rated 1 out of 5 by from Fed up with Magento Dear people at The Great Courses, In the last weeks, very often, when I try to stream a course from my digital library, I get some error indication from a so called Magento Company. Some days it is really upsetting. Please, solve this issue. Thank you PS, please, remove this notice from the "Nature of Matter" reviews, as it is unfair for the course. This issue affects all the courses. It is simply that you ask in the same day the errors are vey frequent.

Rated 5 out of 5 by from Pleasantly surprised I bought this course as a followup to "Redefining Reality" because I was intrigued by the title, "The Nature of Matter." If it had been called "Basic Chemistry" I probably would not have bought it, because nothing in my exposure to the field in high school (50+ years ago) gave me any reason to think I would be interested. I still recall trying (somewhat resentfully) to memorize the valences of various elements without any real understanding of what valences were or why anyone should care about them; so Prof. Ball's discussion of that topic was a real "aha" moment for me. In ordering this course, I had been especially interested in learning more about the atomic and molecular level, where chemistry and physics overlap, and the first half of the course satisfied that expectation in an engaging manner. The real surprises for me were in the second half, where Prof. Ball got into practical applications, such as fuels, recycling, semiconductors, and more. With a basic foundation in chemistry having been laid, I found myself looking at the world around me with different, more appreciative eyes. I agree that the course is aimed at a pretty elementary level; that's why it was a good one for me. I personally found the graphics helpful and would not have wanted to navigate the course without them. In the occasional instances where new terms and concepts came too fast, the synopses in the guidebook were helpful as usual.

Rated 3 out of 5 by from Reviewing the nature of matter So far I have seen the first six lectures. They were good. However, I thought that seeing the professor pace back and forth in front of a stylized blue back ground with funny symbols on it was ridiculous. Having him in a classroom in front of charts showing chemical information would be useful. At lecture six I was particularly repelled by the use of the diagram showing the first ionization energy for removing an electron from an element. The elements are not placed correctly according to their atomic numbers. Lithium with an atomic number of three is placed as though it had an atomic number of nine. This type of error results from the fact that the professor does not have the graph in front of him as he lectures. If he could see the graph that you have produced by computer graphics he would immediately realize that lithium and the other elements are not at their appropriate atomic numbers The other problem I have with your use of computer graphics is that you show the graphic for about fifteen seconds and then you go to the professor who talks about it for about two minutes as he paces back and forth while we cannot see the graphic. This is dumb. Also it would be much more effective to retain the diagram of the periodic table on your screen rather than see the professor pace back and forth as he discusses that diagram which we cannot see.Your use of computer graphics needs improvement. Your final editing of a course needs to be done by students, not video professionals.

Date published: 2016-01-29
Rated 5 out of 5 by from Good Broad Overview This course presents a sweeping overview of key facets of materials science. I especially enjoyed the lectures on polymers and fuels/explosives. It is crammed with applications. It is way technical to start out with, but gets a lot more accessible after the first few lectures.
Date published: 2016-01-23
Rated 4 out of 5 by from Very useful course! I bought this for my daughter to complement what she learns in school, and I can see she is learning something new from each lecture. The Professor's brief explanations of the background behind the new concepts being taught is very helpful for the student to see the big picture. Whereas in other lectures, I have seen my daughter fast-forwarding material, she was very interested in the entire "Nature of Matter" session. We haven't seen all of the lectures, but I think they are excellent.
Date published: 2016-01-21
Rated 5 out of 5 by from Quite a surprise! This course could have taken several directions, but I was most pleased with the down-to-earth approach by this professor. I came away with a good understanding of many physical concepts that I had struggled with for years. I bought a copy of the Periodic Table and really understood it for the first time!

Rated 5 out of 5 by from well worth it I have always loved chemistry, but never had time to really study it in depth. I finally took intro chemistry recently at junior college and even though it was great, a lot was still unclear. This filled in the gaps in a wonderful way. Yes, it is chem 101, but that is where we start and if the foundation is not rock solid anything we build on it will crumble. Now I can move ahead. Thank you! The only reason I give 4 stars for presentation is that I am more used to a teacher behind a desk. He walks around a lot and I find it a little distracting, but that is of course just a style issue.
Date published: 2015-12-29
Rated 3 out of 5 by from Chemistry 101 Despite the title, this is a chemistry course, an introductory chemistry course, and it's targeting an audience that has had little or no exposure to the field. Since my education and work experience is in this field, specifically chemical engineering, I found little in this course that I have not already been exposed to. That said, if the viewer does not have a science background and wants to learn important chemical principles and how they are used in modern society, this is the course for you. The instructor is competent and his delivery and teaching style keeps you interested. There is also some useful crossover topics in physics particularly those in stellar creation and subatomic physics.

Rated 4 out of 5 by from The nature of matter / chemistry for poets This was a valuable course. I had AP chem and an intro to chemistry course in college. I didn't pay as much attention in either as I should have. This course gives one a solid background in chemistry, I think, without getting too in depth. I gained a better understanding of entropy, energy states, and why certain elements or substances are reactive and why others aren't. Other than that, it's an interesting course. You learn something about each of the topics of each lecture. I would say that it was a little too basic for my liking. I am a graduate student in the humanities. I want to know more about how matter functions for my own research. This course was interesting, but not amazing. I would recommend it as a light introduction to chemistry, with a touch of physics here and there. I should say that I thought Dr. Ball was a very good and engaging lecturer. Beyond the basic chemistry, some of the highlights were learning about some of the applications of chemistry to practical matters in the world, e.g. semi-conductors, recycling, etc. Basically, the topics you'll see in the course overview. I would recommend it, but not wholeheartedly. About 4/5 heartedly.

Rated 5 out of 5 by from Enchanting Chemistry This course manages to stay in touch with the magic of chemistry. Generally, I didn't find this quality in either of the courses titled Foundations of Organic Chemistry or Chemistry, 2nd Edition. (The "Why Carbon" lecture of Foundations of Organic Chemistry DOES have this quality.)

Rated 5 out of 5 by from What More Can I Say The other Reviewers have pretty much said it all. I was most grateful for his explanations of atoms & molecules, and the periodic table. But then when I start to think about it, I can't say I appreciated one part more than the rest. A good course on the subject.
Date published: 2015-08-01
Rated 5 out of 5 by from Practical Applications of Chemistry The professor presented a very practical course on materials science/ chemistry. His explanation of the Periodic Table of the Elements was the best ever that I have seen. Each lecture contained practical information, clearly explained. The lecture about recycling is a gem and the entire course is a wonderful discussion about the nature of matter. The professor opens new horizons and encourages further reading and study about the subject. Having a background in electronics engineering, I appreciated the information presented in this course. Best of all, the professor organized the course to appeal to a wide range of interests. I highly recommend this excellent course.
Date published: 2015-07-20
Rated 4 out of 5 by from Why matter matters? This course includes a review of (high-school) chemistry principles. It seems to me very basic. However, I liked the lectures on superconductors, semiconductors and recycling materials.
Date published: 2015-07-16
Rated 5 out of 5 by from The fun side of science. I really enjoyed this course. Once you get through the first couple of lectures the material becomes very qualitative. I am a fan of the more technical (and quantitative) courses that are available through the Great Courses, but the bottom line is that this material would probably be out of reach for many people if it were more mathematical. As I watched this course, I was reminded of the classes that I took in college where the professors would discuss current applications of the material we were studying or share interesting stories about how things in the real world work. This course is 24 lectures of "Wow, I didn't know that." The professor makes the material engaging and entertaining. I hope Professor Ball does another course, perhaps a follow up to this one for those of us who would like a more quantitative peek at the subject. If you like learning about leading edge science and want to learn more about chemistry, you will probably like this course.

Rated 4 out of 5 by from Material Science for Poets This is a very, very simple and basic introduction to material science, building on the most minimal possible foundation of chemistry . For what it is, the course is quite nicely done. It certainly covers a broad range of often fascinating topics, from atomic structure to body implants to super- and semi-conductors, as can be seen from the lecture titles. Professor Ball is a very likable and articulate guide, giving clear and well-organized, if superficial, explanations of these many remarkable phenomena. He speaks in a pleasant, conversational tone which is easy to follow, although he often sounds as if he is addressing middle-schoolers. ("What determines if something bounces? Believe it or not, molecules do!") Absolutely no math or science background is needed to fully appreciate this course. (A few actual equations are thrown in here and there, for no good reason and without adequate explanation, but these can be ignored.) The visuals are plentiful and generally excellent, and I particularly liked the frequent interpolation of topic headings within each lecture to help us follow what is going on. Oversimplification does have its drawbacks, however. These are a few examples, from Lectures 1 and 2, which are just wrong as stated, although later in the course they are clarified: "Entropy is the distribution of energy." "Iron is heavy, lead is heavier." "Temperature is a measure of the energy of a substance." "We have a word for when energy is fixed: quantized." In addition, many times when even a simple explanation would have been appreciated, we must be content with "It turns out that . . ." or "As it turns out . . ." And in Lecture 6, "The Amazing Periodic Table," our professor strains for an analogy to the value of comparing the properties of the elements, and gets it wrong: "Darwin had to compare the beaks of the finches on the Galapagos Islands before he could come up with the theory of evolution." In fact, Darwin didn't have any insight into the finches at all, and certainly didn't figure out evolution by comparing their beaks. That was done later, by others; Darwin developed his theory just fine without them. I will say that Professor Ball's explanation of the periodic table is the least boring I have ever heard! This is quite an accomplishment. I do want to emphasize, though, that I greatly enjoyed the course as a once-over-lightly treatment of an area which I find fascinating. With the above caveats, I very much recommend it. (P.S. - For any that don't know the reference of my review title, basic university physics courses for non-scientists are frequently nicknamed "Physics for Poets." No denigration of poets is intended! Similarly, and with apologies to all of the athletic scientists out there, basic geology is often called "Rocks for Jocks.")

Rated 5 out of 5 by from Fascinating Matter (Audio) The last time I studied Chemistry in any formal sense was about three decades ago when I was in high school. My university training was in physics, and though I eventually did a Ph.D., I was never obligated to take a course in chemistry (and in fact I did not). I have always felt a little self-conscious about being a physicist and yet being almost clueless in Chemistry and have long had it on my list to gain at least a basic understanding. This course fits the bill quite well, but not perfectly, though not through any fault of its own. Roughly the first ten lectures I guess are what you may call classical chemistry. Many basic and important topics are discussed. A prime example is how the elements are formed in stellar processes; some in Supernovas, and others in stellar nuclear fusion processes. Another important topic is the electronic shell structure of atoms, which can only be explained using quantum mechanics. Next, the previous lectures are used to explain the fantastically elegant table of elements, and as a direct consequence, the various complex and fascinating chemical "dispositions" of the various elements such as their tendency to create covalent chemical bonds, ionic chemical bonds, be good solvents etc… Now, all of this was actually pretty fascinating, but almost all of it was not new to me. A lot of it was covered in my high-school studies (which I discovered I remembered much better than I thought), while other parts were covered in my Physics studies. So was it interesting? Absolutely! Was it new? Not so much; but this has to do more with my personal background than with the course itself. From lecture thirteen and onwards, the course changes focus a little bit. The lecturer does not go about teaching the basic concepts of chemistry in great depth from this point on. Instead, the basic chemical concepts are explained rather briefly (I guess there have to be limits on what you can teach about Chemistry in Audio format), and the large part of the lecture is devoted to describing applications of the subjects that are surveyed. Many, many different aspects of matter are tackled. What materials make for good body transplants, what are the chemical characteristics of food? I found these discussions to be absolutely fascinating, and a lot of what was taught was new to me. Naturally, the discussions are very broad, but not very deep. I guess you have to think of them as teasers; if there is something you find really interesting, you will have to find the in depth discussions elsewhere. I really enjoyed Professor Ball's presentation of the course. He conveys a deep enthusiasm for the subject and a deep respect for Chemistry. His tone is casual and light and often tinged with humorous remarks that make the lectures fun to listen to. He does not hesitate to plunge into deep water such as super-conductivity and quantum mechanics – and the explanations are really quite understandable. At least they seemed so to me though I do have a rather solid background in natural science. So overall, this has been a fun course. I thought initially there would be more basic Chemistry that I would learn that I had no clue about before, and that turned out not to be the case. But the broad discussion of different matter and its applications in various fields was extremely interesting and gratifying, so overall the course was well worth the effort.

Rated 5 out of 5 by from Another excellent science course The course covers subjects that are not included in other science courses by TGC, and the professor's delivery is clear and engaging, I have found that one of the major questions concerning the choice of a course is its level, and some people may find too demanding what others think too basic. This course strikes a note which feels right to someone who is (or was) almost completely ignorant of chemistry, and yet expects more than a simplistic overview about the subject. As a bonus, it helped me to better understand some relevant aspects of quantum physics. The standards of the TGC science courses are very high, and this one follows the pattern.
