Rated 5 out of 5 by from Fabulous, Insightful This course is excellent for those who have had doubts about certain aspects of science. It starts out simply (“Yes, if Benjamin Franklin’s kite were hit by lightning he would have been killed") and gradually introduces more complex misconceptions. Lecture 2 (=L2) contains math, but while he shows the basic equations, he explains what they show. Starting in L3 he explains that more accurate equations exist (ie.: the Van der Waals equation over the Ideal Gas Law) and are useful for specialists in the field (ie: the Redlich -Kwong model is even better than the Van der Waals). This is an important part of the course, as he is very good at providing simple insight but doesn’t deny that better models AND even then limitations exist. FAVORITES: L4 “How Flying Works” scratched a life-long doubt: why the Bernoulli equation for fluid flow over the top/bottom of an aircraft wing is wrong. Instead “extremely complex math" (not shown) shows that when the air moves over a wing, it also flows upward creating a lower pressure on the top of the wing AND the wing’s deflection of air creating an upward force on the top. L5 “How Falling Works" nicely explains the befuddling Coriolis effects on long-range cannon trajectory and makes you wonder why you didn’t know the reason that astronauts appear (but are not) "weightless" in the Space Station. L7 gradually builds up to a most amazing paragraph that deserves to be considered in everything from science fiction to sermons. Since atoms are made of quarks, which have little mass, but E=mc2 means that energy and mass are equivalent: “The quarks inside you carry about 2% of your mass. The other 98% is actually just energy. You are force fields, not ‘stuff’ ". Perhaps this perspective will lead to a deeper respect for each other. His L8 summation of the 1962 Drake equation agrees with my personal bias regarding the possibility of alien civilizations. He points out that "...it neglects important parameters” and “...(its) factors (have) to be much rarer than we imagine.” L9 cautions: “Evolution does not mean more complex organisms will form” but rather to variety. The evolution of variety is exquisitely important – without its massive support, how long would we last? L12’s statement that IQs are no longer biased against disenfranchised groups is hopefully correct. His caution that “women tend not to be as interested in the hard sciences” resulting in a skewed IQ vs. college major graph is an old interpretation which might need to be confirmed by a woman led study. CON: L10 emphasizes different gut biomes as responsible for obesity rather than food availability/choices. Perhaps there is some small truth here, but having breakfasted this morning with a restaurant full of obese diabetics eating huge amounts of horrendous “food”, I suspect gut malfeasance is a minor factor. SUGGESTED COURSE ORDER: There are two Great Courses that prepare you for Lincoln’s more complex observations, especially L7, L13, L22-24: "Impossible Physics" by Shumaker and “Particle Physics for Non-physicists" by Pollock were useful preparations. Shumacher is good for physics “newbies" and discusses topics including perpetual motion machines, what absolute zero entails, symmetry, quantum cloning, conservation of energy and charge, time travel, FTL, the uncertainty principle, and whether one can predict the future of a chaotic system. Pollock creates a story about the mental steps it took to arrive at an increasingly accurate understanding of the particle nature of the universe. CONCLUSION: The last two lectures of this 2019 course brilliantly explain why quantum observation (and Schrodinger’s Cat) “does not require a mind”; why a Theory of Everything seems to need a single building block and a single force; where dark matter doesn't fit in; how the Higgs boson confirmed that the 4 forces of gravity, electromagnetism, the weak nuclear and strong nuclear forces have now become (on the quantum level) gravity, the strong nuclear force, and the electroweak force; and briefly mentions “Superstring Theory" as the “imagined connection...that might be right”. QUIZZES: The 4 quizzes are fabulous AND they have answers! Each question actually helps you better understand the course lectures. Take the quizzes!

Rated 4 out of 5 by from Good but needs more metaphysics The physicist seeks to improve milk production by postulating a spherical cow that radiates milk in all directions. There is no such cow. Dr. Lincoln knows that; however, by lecture 20, he discusses the Big Bang theory as if it were factual Gospel. Please consult I. Kant, Thos. Kuhn and/or Alvin Gouldner for the appropriate grain of salt to add.

Rated 5 out of 5 by from Clear and understandable to the non scientist This is one of the best lecture series I've done, and I've done at least 15. This lecturer is engaging and lucid. He explains complicated ideas in simple terms so that a non scientist can understand. I think all high school students should watch this course. I'm not in high school any more, but I wish I had a teacher this good when I was. I knew most of the concepts and didn't have a lot of misinformation myself, but I understood many concepts in physics much better after watching this course. BTW, there were 2 physicists in my family.

Rated 4 out of 5 by from Fascinating Most topics left me wanting more, probably a very healthy response. I do have a caveat to add to the Statistics presentation. Large numbers can provide a "significant" result, but really that is "statistically significant" and not necessarily practically significant. A treatment for cancer that only extends life one day is not medically useful, nor is a pricey product modification that extends use by one day likely to be adopted by the manufacturer. Yet given a large enough sample base, either of these can be statistically significant.

Rated 1 out of 5 by from A disappointment I enjoyed the first episodes of the course. The lecturer seemed well informed. But in the later episodes seemed slipshod and uninformed. The episode in which he opines on IQ is awful. He cites approvingly a WSJ article "Mainstream Sciences on Intelligence" signed by many psychologists defending the Bell Curve view as if stated established science. It isn't-- see the Wikiipedia entry on the article
