Publication of a research work to Rudolf Steiner's statements and scetches on the planets' lemniscatory paths. For the first time in almost a hundred years, Rudolf Steiner's statements and sketches on the subject of the "Lemniscatory paths of the planets", distributed over several lecture cycles, have been brought into a larger context and examined for the consequences of this. Steiner's suggestions for a new consideration of the planetary movement were taken up and tried to develop them further in the given sense. The work "The Lemniscatory Path System" arose from this. The treatise comprises 192 pages with 253 mostly coloured illustrations.

In this article the author uses techniques from algebraic geometry and homological algebra, together with ideas from string theory to construct a class of 3-dimensional Calabi-Yau algebras. The Calabi-Yau property appears throughout geometry and string theory and is increasingly being studied in algebra. He further shows that the algebras constructed are examples of non-commutative crepant resolutions (NCCRs), in the sense of Van den Bergh, of Gorenstein affine toric threefolds. Dimer models, first studied in theoretical physics, give a way of writing down a class of non-commutative algebras, as the path algebra of a quiver with relations obtained from a `superpotential'. Some examples are Calabi-Yau and some are not. The author considers two types of `consistency' conditions on dimer models, and shows that a `geometrically consistent' dimer model is `algebraically consistent'. He proves that the algebras obtained from algebraically consistent dimer models are 3-dimensional Calabi-Yau algebras. This is the key step which allows him to prove that these algebras are NCCRs of the Gorenstein affine toric threefolds associated to the dimer models.

The present English edition is not a mere translation of the German original. Many new problems have been added and there are also other changes, mostly minor. Yet all the alterations amount to less than ten percent of the text. We intended to keep intact the general plan and the original flavor of the work. Thus we have not introduced any essentially new subject matter, although the mathematical fashion has greatly changed since 1924. We have restricted ourselves to supplementing the topics originally chosen. Some of our problems first published in this work have given rise to extensive research. To include all such developments would have changed the character of the work, and even an incomplete account, which would be unsatisfactory in itself, would have cost too much labor and taken up too much space. We have to thank many readers who, since the publication of this work almost fifty years ago, communicated to us various remarks on it, some of which have been incorporated into this edition. We have not listed their names; we have forgotten the origin of some contributions, and an incomplete list would have been even less desirable than no list. The first volume has been translated by Mrs. Dorothee Aeppli, the second volume by Professor Claude Billigheimer. We wish to express our warmest thanks to both for the unselfish devotion and scrupulous conscientiousness with which they attacked their far from easy task.

A Loving Tribute To A Unique Upbringing When Stephen Alter Is Asked The Simple Question Where Are You From, Originally? He Hesitates. Although He Is In Almost Every Way An American-Granted With A Trace Of British Accent-He Has An Unexpected Reply: My Real Home Was In India, A Hill Station Called Mussoorie, Seven And A Half Thousand Feet Up The Himalayas. That Was Where I Was Born And Raised, In A Section Known As Landour... It Is A Landscape, And A Time, That Haunts Him Still: I Miss The Place Itself; The Mountains, The View Of The High Himalayas Beyond Mussoorie, Stretching All The Way To Heaven. The Son And Grandson Of Presbytarian Missionaries Living In India For More Than Half A Century, Every Day Alter Straddled The Profound Boundary Between Utterly Different Peoples, Cultures, Languages And Religions. He And His Brothers Spoke A Pidgin Dialect Of Hindustani And English As Young Boys, Fished In The Rivers Song, Ganga And The Jumna, And Later Hunted For Barking Deer And Ghoral In The Steep Foothills Of The Mountains Always Looming Behind Them. They Studied American History But Knew More About India'S Recent Independence From England. In All The Way To Heaven, Alter Writes Affectionately Of His Family, His Indian Friends And His Memories Exotic And Mundane.
