Course Overview

Cosmology. Neurology. Genetics. Chemistry. These are just a few of many fascinating branches of the scientific world ripe for exploration. But because science is such a vast arena of knowledge, people looking for a better grasp of its secrets often wonder where to begin. The answer: with the essentials.

Science’s most vital concepts and ideas—some of which have been around for centuries, others of which we’ve only uncovered in recent decades—make the perfect starting point for a deeper dive into regions of the scientific world you’ve long wanted to take a closer look at. Whether it’s evolution, electromagnetism, thermodynamics, or the nature of matter, these and other eye-opening concepts are all connected by the profound role they play in our everyday lives and in our larger understanding of the world.

By narrowing your approach to the expansiveness of science and drilling down to some of its essentials, you’ll

  • grasp the true nature, challenge, and excitement of scientific inquiry;
  • shed light on the scientific marvels of today and tomorrow, from nanotechnology to artificial intelligence;
  • develop a solid foundation of knowledge that will put more advanced areas of science within your reach; and
  • enhance your sense of wonder at the hidden marvels of everything from driving to work to creating new memories.

With 12 Essential Scientific Concepts, you can finally satisfy your desire for scientific inquiry in a way that makes this enormous field accessible, understandable, and undeniably captivating. Indre Viskontas, an award-winning cognitive neuroscientist affiliated with the Memory and Aging Center at the University of California, San Francisco, has a knack for making hard science clear to laypeople. She boils down the scientific world into 12 key concepts every educated person should know. Devoting two lectures to each concept to give you more time to engage with it, her 24-lecture course is your introduction to everything from the behavior of subatomic particles to the latest theories about the Big Bang. Concepts that may have eluded you in school, that you may not be familiar with, or that you simply never appreciated for their intricate beauty are now brought to vivid life in a way that sticks. Welcome to the world of science—reduced to its powerful essence.

Explore 12 of Science’s Bedrock Ideas

This course is your chance to get a single, accessible way to explore essential concepts from a broad range of scientific areas. Professor Viskontas offers you an engaging and accessible look at key building blocks of scientific knowledge.

  • The modular brain: With so many intricate, scattered parts and actions going into how human beings perceive the world, how is it that we experience reality as a seamless, coherent story? This is where the mind-boggling concept of modularity and coherence comes into play, which probes how our conscious experience emerges.
  • Brain plasticity: Scientists now understand that our brains act like plastic, in that they can be molded over time into many different shapes—a concept that’s caused a radical paradigm shift in the field of neuroscience. From breaking bad habits to learning new ideas, brain plasticity encompasses the tiniest modifications to a single brain cell to sweeping changes across neural circuits.
  • Quantum theory: How do we explain the behavior of particles smaller than an atom? The answer lies in the concepts of quantum mechanics, which operate within a unique set of mathematical rules and formulas different from those in classical physics. And, as you’ll learn, the ramifications of quantum theory, in everything from robots to supercomputers, are astounding.
  • Emergence: The quest to understand how complex systems work lies at the heart of the concept of emergence, where simple agents (following simple rules) together perform complex feats impossible for any individual unit to accomplish on its own. Where can you see emergence at work around you? It’s in everything from migrating flocks of birds to the layout of your neighborhood. But it may explain human consciousness as well.

You’ll also investigate other essential concepts: life, evolution, genetics, electromagnetism, thermodynamics, fluid mechanics, the Big Bang, and the nature of matter. For each of them, Professor Viskontas gives you an expert’s introduction to their key ideas, the math and science behind them, the great minds responsible for uncovering them, and their relevant applications to (sometimes surprising) areas of life.

Learn Eye-Opening Scientific Facts

Every lecture of 12 Essential Scientific Concepts is filled with a sense of wonder and awe at the knowledge that scientific inquiry has brought us. Just as memorable as the concepts you explore are the eye-opening facts you’ll learn along the way.

  • Hurricanes transform heat into work much more efficiently than a car or jet does; so much so that a tropical cyclone can release heat energy at a rate of 10 to 15 watts per day—about 70 times the daily world energy consumption, or the equivalent of setting off a nuclear bomb every 20 minutes for the life of the storm.
  • The Big Bounce, a possible alternate theory for the origin of the universe, posits that before the Big Bang, there was no singularity but instead a tiny, compressed universe that preceded it. So instead of a beginning of everything, there could just be an infinite loop, of which we occupy a small part and during which the universe expands and contracts for eternity.
  • One possible explanation for the emergence of the theory of mind (the recognition that other people have thoughts, desires, and goals just as we do) lies in so-called “mirror neurons” that encourage babies to mimic other people’s actions. These specific neurons also offer neurologists a solid case study for how sentience and self-awareness might emerge from simple cells.

Spark Your Curiosity about Science

Regardless of how complex the concepts may appear at first, Professor Viskontas always takes care to present each one in a clear and concise way that will inform and delight you. She brings her remarkable teaching talent as well as an undeniable passion for sharing the wonders of science with an audience eager to learn.

An experienced observer of human behavior, Dr. Viskontas has published groundbreaking work on the neural basis of memory and creativity and has won numerous research awards. And as a professor of music at the San Francisco Conservatory of Music, she is pioneering the application of neuroscience to musical training and performance.

Accompanying you on this exploration are hundreds of informative visual elements to aid in your understanding, including green screen technology, helpful in-studio demonstrations, and explanatory 3-D graphics and animations. These captivating enhancements add an even greater level of depth and clarity to 12 Essential Scientific Concepts, giving you the opportunity to probe the invisible life of living cells, to tour the tiniest corners of the human brain, and even to visit the universe seconds after its birth.

Above all, Professor Viskontas has crafted this course to excite you for the countless possibilities ahead. “Science doesn’t reduce our imagination, it expands it,” she says. “Instead of quenching your curiosity, I hope I’ve sparked it—because there’s so much more to explore.”

  • 1
    The Miracle of Life
    To truly understand what makes life special, you have to understand the fundamental makeup of life. In this first lecture, investigate the basic chemistry of living organisms, from the fundamental importance of water and carbon to the critical functions of proteins—the molecules that allow cells to survive, reproduce, and adapt. x
  • 2
    The Organization of Life
    Turn now to cells and the intricate organization of life. As you take an in-depth tour of eukaryotic cells (the kind your body is made of), you’ll learn how to make sense of mitochondria, lysosomes, and other cell parts. You’ll also see cellular organization at work in everything from making proteins to generating energy. x
  • 3
    Evolution—The Tireless Tinkerer
    Today, Charles Darwin’s landmark theory of evolution is biology’s fundamental organizing principle. So how did this revolutionary idea come about, and what were its roots? What scientific evidence proves the fundamental importance of evolution? What do antibiotics reveal about how the tireless tinkering of natural selection works in everyday life? x
  • 4
    Other Mechanisms of Evolution
    Explore some alternative mechanisms through which species can change, including genetic drift and gene flow, and the key role allele frequency plays in our understanding of evolution. You’ll also examine the Hardy-Weinberg principle, used by evolutionary scientists to determine whether a population is actually evolving, and which mechanisms are driving the evolution. x
  • 5
    DNA and Heritability
    Professor Viskontas takes you back to the birth of genetics through the pioneering work of Gregor Mendel. Then, she shows you how to understand DNA as a simple code read by cells to produce new cellular components. And finally, she breaks down the complexities of how genes express themselves: through the generation of proteins. x
  • 6
    Epigenetics, Mutations, and Gene Insertion
    It turns out that our genes aren’t fixed but change across our lifespans. In this fascinating lecture, investigate three major ways in which that happens: epigenetics, the modification of gene expression through environmental changes; mutations, which involve alterations in the genetic code; and gene insertion, in which viruses play a surprising role. x
  • 7
    The Illusion of Coherence—How We See
    The way you see is modular—but your consciousness is coherent. How is this possible? To answer this perplexing question, you’ll explore the biology of the eye and investigate the curious “binding problem” at the heart of the intersection between neural physiology, cognition, and the philosophy of consciousness. x
  • 8
    Acoustic Perception Deconstructed
    First, get a better understanding of how our ears are built, and how that construction affects the hearing process. Then, learn why hearing loss offers the perfect demonstration of just how complex this process is. Finally, consider the essential subjectivity of pitch and how hearing and sight interact with one another. x
  • 9
    Our Changing Brain
    Science has revealed that our brains actually change shape over time. But how? Where in the brain does this occur? How are memories created? What is the relationship between brain plasticity and learning (or unlearning) skills and habits? These are just four of the many questions you’ll encounter in this first lecture on neuroplasticity. x
  • 10
    Plasticity, Brain Training, and Beyond
    Delve deeper into the implications of neuroplasticity, and how we can harness its power to stave off the cognitive effects of aging, recover from disease, and master complex skills. The secrets lie in specific parts of the brain, like the hippocampus and specific proteins, like the brain-derived neurotrophic factor, or BDNF. x
  • 11
    Magnetism and Its Magic
    Magnetism is undoubtedly a strange aspect of the scientific world. Here, Professor Viskontas reveals what we know (and have yet to uncover) about magnets and how they work. You’ll learn what makes a magnet magnetic, how spinning electrons create magnetic fields, the secrets of ferromagnetism, and much more. x
  • 12
    Electrical Forces, Fields, and Circuits
    To truly understand magnetism, you have to understand its cousin: electricity. First, get a primer on the basics of electricity. Then, explore the concept of electric potential (a combination of an object’s electric charge and its position to other charged objects) and find out how electric circuits actually work in the human body and beyond. x
  • 13
    Thermodynamics—Heat, Energy, and Work
    Explore the concept of power in the inanimate world—as predicted through the three fascinating laws of thermodynamics (which describe the relationship between heat and work). Along the way, you’ll understand how an ideal engine works and witness thermodynamics in action through the famous examples of steam and internal combustion engines. x
  • 14
    Metabolism—Energy in the Cell
    See how the laws of thermodynamics apply to metabolism, the energy exchanges between cells that keep us alive. Explore the inner workings of metabolism with detailed investigations of photosynthesis and cellular respiration. Learn how metabolism plays a role in today’s metabolic engineering, a process by which we harness single-celled organisms to create useful products. x
  • 15
    Fluid Mechanics—Pressure, Buoyancy, Flow
    Professor Viskontas offers you a clear explanation of how aerodynamics (or fluid mechanics) works. Central to this illuminating lecture: the opportunity to finally make sense of the fundamentals of this scientific concept, including buoyant force, the relationship between pressure and depth, Bernoulli’s equation, and the equation of continuity. x
  • 16
    Navigation and Propulsion in Fluids
    How has our greater scientific understanding of fluid mechanics given us the tools to move (and dominate) the land, sea, and air? How do we power the machines that allow us to do so? What’s the difference between form drag and skin friction? What’s actually happening when your plane hits turbulence? x
  • 17
    The Big Bang That Didn’t
    Travel back to the very start of time and navigate the murky—but undeniably eye-opening—science behind the Big Bang. As you evaluate this scientific theory by considering the evidence available, you’ll also ponder three ways the universe could end: the Big Crunch, the Big Freeze, and the Big Rip. x
  • 18
    The Four Forces of Nature
    Explore the four fundamental forces of nature, which scientists believe have guided the formation, expansion, and essence of our universe since it began. Not only will you learn the nuances of the strong force, the weak force, the electromagnetic force, and gravity—you’ll learn the practical implications this knowledge has given us. x
  • 19
    The Elements of Everything
    Break down the elements of the periodic table and discover how it explains why elements behave the way they do—and points the way to elements that we have yet to discover. Afterward, peek inside the atom and explore subatomic particles, including fermions and the long-elusive Higgs boson. x
  • 20
    Looks like a Particle, Acts like a Wave
    Is light a wave or a particle? To find the answer, comb through revolutionary ideas by Max Planck and Albert Einstein to encounter the wave-particle duality (a paradox best captured by the famous Heisenberg principle). Then, investigate some of the applications of this duality, specifically through the development and use of lasers. x
  • 21
    Quanta, Uncertainty, and a Cat
    Quantum mechanics is full of strange contradictions, including a cat that is simultaneously alive and dead. Professor Viskontas introduces you to the Copenhagen Interpretation—the most popular (though still not universally accepted) way to think about this field. You’ll also consider some of quantum mechanics’ remarkable applications, from nanoscience to quantum computing. x
  • 22
    String Theory, Membranes, and the Multiverse
    What exactly is string theory? What can M-theory and the behavior of black holes reveal about it? How does the theory of Loop Quantum Gravity explain how gravity works at the quantum level? Answers to all this and more are here in this lecture on a mind-bending scientific concept. x
  • 23
    Emergence—Simple Rules, Complex Systems
    The science of emergence explains how simple agents together perform complex feats that are impossible for individual agents to accomplish on their own. Consider what emergence can tell us about seemingly chaotic scenarios through several case studies from wildlife, including ant colonies and flocks of birds. x
  • 24
    Order out of Chaos
    Continue your look at the most interesting ideas in emergence. First, learn about artificial intelligence and social robotics. Then, ponder the rise of the theory of mind and human self-awareness.

12 Essential Scientific Concepts is rated 4.0 out of 5 by 56.
Rated 2 out of 5 by from Distracted by the condition of the lecturer The content was ok, and the professor did an adequate job. But I feel The Great Courses was wrong to use a very pregnant-looking college professor for this course. Bought it for my young nephew and brother for Christmas. Despite the content, they found it hard to concentrate on the subject matter. With the enceinte condition of the presenter on such obvious display. I feel that The Great Courses should have delayed taping this lecture a few months until the lecturer had her baby. My nephew and brother wanted to see examples of great scientific concepts. NOT the fecundity of the lecturer!
Date published: 2018-01-28
Rated 2 out of 5 by from 12 Essential Scientific Concepts Honestly I'm disappointed. I feel I should have bought the book since she reads her text and she is not as engaging as other professors. Not disputing the content but I find myself drifting away sometimes listening to the course.
Date published: 2017-12-11
Rated 2 out of 5 by from - little feel for the topic Wife & I bought this- didn't find that it conveyed an understanding of the basic ideas and focused on very specific examples/topics rather than the overall concept. It's been a couple of years and I don't recall a lot of details but we gave up without completing the series
Date published: 2017-11-01
Rated 5 out of 5 by from Fine introduction Maybe I shouldn't review this, as I skipped all the biology classes (I have an advanced degree in microbiology). But I need to say that I immensely enjoyed the physics classes; I thought her presentations were very clear. I would suggest this to anyone wanting an introduction to current science. She covered a topic I had no exposure to,namely emergence (hello, Amazon.... I bought two books). The professor profile says she's an opera singer as well as a scientist. I would like to have heard her, but considering that she was discussing gravity, organic chemistry, and quantum mechanics, it was not at all obvious where music would go....
Date published: 2017-08-03
Rated 5 out of 5 by from I'm thoroughly enjoying this course, but taking my time with it because it has been 53 years since I graduated college and my major in under grad and graduate level was lit, not math or science. Reading the course material before I watch the video helps me get it and I will watch it all again because repetition definitely helps. Thank you! I have another one which I'll watch after this one. I'm looking to fill in the gaps because my knowledge of physics was very limited before watching this course.
Date published: 2017-05-27
Rated 4 out of 5 by from very well presented. approach to the topics not quite what I expected, but demost rated a thorough knowlegde and skill in making the subjects interesting. I'm not certain who the target audience is,but some science background is useful in füll appreciation of thr information. highly recommend ,but not for everyone
Date published: 2017-05-22
Rated 5 out of 5 by from Excellent course! I love this course. I really like the way this was done. This is the only course that I bought twice. The first one was the audio, it was so good that I had to see it. So I bought the video version. Buy the video version. I have bought other courses because of what is in this one. Well done.
Date published: 2017-04-24
Rated 4 out of 5 by from Need a team teaching approach Choosing only 12 concepts from science to cover is a difficult task and these 12 are well chosen. My studies have been in physics and not life sciences and I hoped the first half or so of this course would begin to fill in some gaps in my education. I was not disappointed. What I did not expect was Dr. Viskontas would do such a great job of relating basic physics concepts to physiology and biology. Because of that, her lectures on thermodynamics, energy and fluid mechanics were very illuminating even though the physics content was quite basic. This view of these concepts would be very helpful to any physics teacher. I also hoped that a neuroscientist would have much to add to my understanding of hearing and vision. The discussion of the problems of creating a unified sensory experience in the brain was exciting as well as amazing. I would say the first 16 lectures were excellent and often exceeded my expectations. The last 8 however met my (much lower) expectations. No one can be expert at all 12 of these concepts and given her background it was no surprise that these last lectures were more superficial and lacked any novel insights. They were much more like reading an article in a popular magazine than a college level class. This course would have benefitted from a team teaching approach where the last third was handed off to someone with a background in physics or cosmology. The middle third would have benefitted from combining their knowledge and backgrounds as well but her ability to relate those concepts to her personal experience carried it off. While there were a few things to quibble about in lectures 17 through 24 there was one serious error that should be corrected. When a violin string vibrates more strongly (louder) the peaks get larger but their spacing does not change. That would mean their wavelength and therefore their pitch would change and this does not happen. If it did, you couldn’t tune a stringed instrument because the pitch would change as the loudness decreased. In contrast, when the energy of a photon or an elementary particle increases, the wavelength does decrease and presumably the same is true in string theory. Another mistake is in the guidebook question for lecture 15. When you put your thumb over the mouth of a garden hose the pressure in the fluid does not increase. The speed of the fluid increases and when this faster flowing fluid hit pebbles in your driveway it knocks them harder. This is difficult to get students to understand so it’s bothersome when an instructor gets it wrong. But it really just shows when anyone tries to cover such a wide range of topics, multiple editors with various backgrounds should be used. A final comment is about her speaking style. If you are put off by it in her first lecture don’t give up. I almost did and I would certainly have lost a lot if I did so. In the first lecture, following all those rules of good public speaking she modulates her voice in pitch and intonation and changes the speed of her speech in exaggerated and unnatural ways. It reminded very strongly of Miss Nancy from Romper Room speaking to 4 year olds! With each subsequent lecture however, she relaxed and it became first less annoying and by the last half she did quite well.
