Gravity - an eye opener

Date:February 20, 2014

" We tend to take gravity for granted ... the apple falls from the tree. How can this require 24 lectures? However, Professor Schumacher takes this basic premise, using an historical perspective, and takes the viewer on a journey of discovery into what gravity really is, and isn't. He is a great teacher, always engaging the audience, and able to put complex concepts into a framework that can be understood by the non-astrophysicist even though they are not intuitive. And, as indicated in the title, concepts including tides and black holes are integrated into this grand concept of gravity. Professor Schumacher does a wonderful job in laying out what turns out to be a very interesting, yet complex, topic.

Opens up a difficult subject to the layperson

Date:January 17, 2014

" This course offers a good historical, largely qualitative introduction to students interested in the study of gravity. The mathematics in the course are not so rigorous as to alienate viewers with a modest background in Algebra, but probably won't satisfy the student seeking a more quantitative exploration of gravity.

My background is in accounting and economics and I had no trouble following the equations. In a number of places, professor Schumacher obviously employs metaphor as substitute for mathematics, which, again, may or may not appeal to one, depending on his or her background.

As far as content goes, although much of the material on gravity and black holes is covered in earlier Great Courses, in my opinion, there is enough new material and fresh takes on the topics here to warrant the purchase.

One thing deserves special mention. The professor did a superb job of anticipating and addressing questions which occurred to me during the lectures. One such question involved how black holes are believed to have formed at the center of galaxies. As this particular lecture wound to a close, I felt certain that he would not answer the question, but, in the end, he did. This occurred several times during each lecture and I can't applaud professor Schumacher enough for it.

If one is new to the subject, perhaps professor Filippenko's excellent course on Astronomy and/or professor Carroll's equally excellent series, "Dark Matter, Dark Energy," might help to lay the groundwork for this course.

Excellent

Date:November 14, 2015

" I bought this in honor of the 100th anniversary of Einstein's greatest discovery, and have been completely satisfied. Professor Schumacher has an engaging and non pretentious style, is clearly a master of the subject, and neatly weaves together the history of the evaluation of gravity and its effects. I particularly enjoyed how he pays tribute to the discoverers since Gallileo and shows how Einstein's discovery is based on the efforts of geniuses from the past. Like many of the Great Courses professors, I constantly ask myself "where were these guys when I was in college?".

Exceptional great course - Dr Schumacher is superb

Date:November 3, 2015

" This is the second physic course presented by Dr Schumacher that I have taken ("Impossible: Physics beyond the Edge" was the first#. He was great in the first but even better in this one. He makes this extremely complex subject understandable. I was taught that a good presenter should "tell them what you're going to tell them, tell them and then tell them what you just told them". Dr Schumacher used this approach with great effect. In this course he reviews Newtonian physics and then goes over in detail the revolutionary changes introduced by Einstein's laws of general relativity. He then goes on to discuss a wide range of phenomena including curved spacetime, gravitational tides and black holes plus a brief excursion into other modern physics theories #string and m-theory#. I was truly impressed with the excellent organization and presentation of this Great Course.

another brilliant physics course from TGC

Date:May 16, 2015

" i love how the TGC physics courses help you unlearn most of the nonsense you were fed at school - you end up with a picture of our cosmos you can only marvel about and the realization that we still have a looong way to go in our understanding. Professor Schumacher can explain complicated stuff extremely well, even better than Sean Carroll, who is another favourite from the TGC courses. I hope to see more courses by these brilliant teachers in the future. Keep up the good work! :)

" The Professor makes what is a very difficult subject quite understandable. The brief descriptions of the various individuals who were so important in the development of our knowledge of this subject was greatly appreciated.

His examples of how to under the complex mathematics was a definite boon. This course certainly helped me bring together the disparate pieces of information that i already knew about this subject. "

A physicts view of gravity

Date:February 3, 2015

" Professor Schumacher's lectures were word for word of what was in the guidebook that came with the course. One could just read the guidebook and not watch the disc. The only extra thing the disc provided was some pictures of the cosmos and diagrams of descriptive models in the guidebook. His lectures were filled with physics equations to back up his points. Those who just want a basic understanding of gravity and not accustomed to heavy math equations might become put off by so many equations and not finish the course. Without the time on the equations the course would be only 6 lectures long. He also seems to have a very extreme regard for Newton though Einstein and others have corrected some of his theories. His lecture on the quantum physics of gravity was very weak and could have been omitted from the course. I wouldn't recommend this for anyone who wants just a basic understanding of gravity, especially for one who isn't acquainted with mathematical equations.

Concepts Clearly Explained

Date:January 31, 2015

" I was a physics major and can confirm that only the most basic general relativity was offered to undergraduates. There are two reasons for that. First, undergraduates don't yet have the mathematics to master general relativity. Even Einstein needed help with the math! Second, undergraduates need to cover lots of other areas of physics as well. (To ensure my education was not unusual, I confirmed this with a friend who agreed they had the same experience as a physics major at a different college. Ok, a sample space of two, but that's all I had time for.)

How, then, could Schumacher teach this course? Instead of spending a great many lectures on teaching us math, he instead concentrates on concepts. And I, for one, believe he did an excellent job with those concepts. I really enjoyed this course and have a much better understanding of gravity. His explanations are clear and the drawings, graphics, and other illustrations really helped.

Although I have a physics background, I think anyone could understand the concepts in this course. I have all of Schumacher's courses and can't wait for him to do more.

Excellent explanation of a difficult topic

Date:January 31, 2015

" It's difficult for a non-physicist to wrap the mind around the concept of space-time, but the professor does an excellent job of explaining gravity in a reasonably understandable way. Combined with some other courses, such as those on Time and Quantum Mechanics, the universe is becoming a little more clear.

Difficult, but I would recommend to anyone

Date:January 8, 2015

" The concepts regarding gravity are very abstract and complex, but the professor uses analogies, concrete examples, and visual aids to make them more accessible. He starts with easily understood math and builds on that to what would otherwise be abstruse equations. He humanizes the subject by giving an historic and philosophical background. The course is well balanced in that he emphasizes both the theoretical and experimental aspects of the science. Moreover, his love of physics is infectious. Because of his enthusiasm and knowledge I would recommend this course to anyone.

" If I could give Professor Schumacher 6 stars I would. Having read fairly widely in physics as a non-scientist before I bought and viewed this course, I brought some high expectations to it. Professor Schumacher hit the mark precisely with this course. It's a fascinating and exceedingly professional presentation. I'm convinced that if more young adults had science professors of this caliber then we'd have more scientists. Very well done, Professor.

Many ambiguities and even errors

Date:August 10, 2014

" I could forgive minor errors such as "Galileo invented the telescope" and "Laplace was born an Italien" but the misleading graphics for the eotvos experiment and even the explanation of the tides reminded me of similar problems with another course I bought (quantum mechanics). It is not bad to have to go to Wikipedia to get the story straight but I am not accustomed to this from the Teaching Company.

Ambiguities and Errors

Posted March 4, 2015

First, I have just begun the course so am not ready to review it. Further I have not checked the accuracy of the information in question. What I do question however, is the reliability of Wikipedia. At the high school where I teach it is locked on the school's network as a research source for our students due to its poor reliability history. It has its uses, but if and when I do look up any facts I need to check, it will not be on Wikipedia.

One of the Best - A Home Run

Date:August 6, 2014

" Professor Schumacher has done a masterful job of giving all of us a thorough introduction to the many concepts presented in this course. There was just enough math to illustrate his lectures. Whenever he used a term that he wasn't sure it familiar to the audience, he carefully explained.

I especially liked his out from behind the lectern approach to teaching. He handled some complex topics with an aplomb only possible with both confidence in his knowledge and his teaching style.

Excellent! I recommend it.

Hard Topic Made Accessible

Date:June 1, 2014

" Once again, Dr. Schumacher has nailed it. He's incredibly clear, concise, articulate in a way that's inviting us to, in a sense, participate in his explanation and excitement of the topic.

He repeats and reviews previously presented concepts all throughout the course such that by the end the important concepts have been driven home.

Whereas he does derive (in a very simplistic way, of course) the equation of the "curvature" of spacetime, he does it in a completely logical and understandable way - he simplifies the concepts but takes it to the next level where important.

His lectures have spanned Quantum Mechanics, unusual Physics, and now Spacetime. I look forward to his next course no matter what it might be. He is clearly one of the finest lecturers in The Great Courses roster and this is one of the best courses.

" Purchased this course to fill in the blanks left over from previous astronomy and cosmology courses purchased from the Teaching Company. The course and course content far exceeded my expectations. What Greenberg is to music, Schumaker is to physics and astronomy. Course material covered the history of gravity science from Galileo to Einstein and beyond. But beyond its historical perspective, gravitational concepts were presented which allowed an understanding of how the Universe works and some insight into the problems facing science today in marrying Newtonian gravity with Quantum theory. Complex issues were discussed clearly. Some familiarity with basic algebra is required to fully comprehend the complex issues presented. A first class course!

" I was already familiar with many of the concepts in this course but the presentation was so compelling that the sum was far more than the parts. The words that come to mind, insightful, provocative, thought provoking, profound are all insufficient. What a truly wonderful synthesis of so many related topics.

My only regret is that I have but 5 stars to give to this course!

An excellent survey

Date:December 4, 2013

" Prof. Schumacher has a knack for reaching the most interesting pinnacles of the subject with a minimum of background preliminaries. It's good that he didn't attempt this class under the frequent "no equations" constraint, but also good that he kept the equations to an unintimidating level. This class is for the student looking for the meaning behind the equations, and Prof. Schumacher focusses on that meaning. I'm content to look for the mathematical details elsewhere.
