Hybridization Geometries & Bond Angles Understanding the terminology and geometries of hybridized orbitals (part of the valence bond theory). sp = linear = 180 deg sp2= trigonal planar = 120 deg sp3 = tetrahedral = 109.5 deg dsp3 = trigonal bipyramid = 120 and 90 d2sp3 = octahedral = 90 deg I also give a brief explanation of sigma and pi bonds, hybridization, and some of the predictions you can make once you've studied the theory. No, the valence bond theory isn't perfect (consider the paramagnetic properties of O2). It also does a really bad job of predicting some of the real bond angles (measured by crystallography and spectroscopy experimental methods). Overall, it's still a useful explanation. ...It's helped us understand bonding enough to make predictions about unknown molecules that can be verified by experiment. :) I find this fascinating! :) hehe

Lecture 8: Hopper Design Example - determining hopper geometries - Joe Marinelli In Lecture 8, Design Example, Joe Marinelli of Solids Handling Technologies takes you through a typical design example. The example begins with an assignment you may receive to design a bin and feeder to reliably handle your product. Joe discusses the actual data plots that would typically be generated during testing of your materials and their interpretation. He uses the Jenike design approach to calculate opening sizes and hopper angles. Joe discusses minimum opening size calculations and hopper angles for mass flow conical hoppers and wedge type hoppers. He also describes funnel flow bin designs requiring calculation of your materials rathole dimensions. A design is ultimately created according to the data and calculations made during the presentation.Lecture includes downloadable class notes and a self administered quiz with answer sheet. The seven-day subscription allows you to watch and review this video class as many times as you need.

Animation depicting Fuller's geometric explorations - Whitney Museum Digital animation by Michelle Chang with Helen Han and Temple Simpson. This animation presents the geometry that is the basis of many of Fuller's key ideas and concepts. At the beginning, twelve spheres are packed as closely as possible around a single central sphere. As the spheres shrink and disappear, they generate a polyhedron in which all edges and all radii are of equal length. This shape is what Fuller called a vector equilibrium. One of the characteristics of a vector equilibrium is its ability to contract by folding in on itself. The animation demonstrates how this simple geometric shape can be transformed to create several complex polyhedra. Next, it produces a different version of a vector equilibrium that Fuller called tensegrity—short for a stable structure of tensional integrity. In the last part of the animation, a map of the entire globe is transferred onto the vector equilibrium, which unfolds to produce a flat map of the earth made from six squares and eight triangles. Unlike conventional world maps, Fuller's vector equilibrium map represents the world with minimal distortions to the relative size of the continents. For more information on Buckminster Fuller, visit

Euclidean & Non-Euclidean Geometries Part 3: Definitions In Part 2, I said that Part 3 would tell what the axioms of Euclidean geometry are. Instead, this is the first video entirely about definitions. There will be another later in the series, but not immediately. The undefined terms are: point line lie on between congruent
Euclidean & Non-Euclidean Geometries Part 1 This is a series of videos ostensibly about geometry; however, if you don't already know some geometry, you're unlikely to learn it here. The series was inspired by Prepoceros' video about differences between proving theories and theorems and some mind-boggling (to me) points I learned from a non-Euclidean geometry course many years ago. I am going to emphasize the roles of definitions and axions way way more than one might think necessary, considering that I am already assuming some knowledge on the part of the listeners. Trust me. Although I don't say so until Part 5, this is about plane geometry unless I explicity say otherwise, which I haven't done at least through Part 5. Don't look for any elegant proofs in these videos. The book that I am borrowing ideas, anecdotes and other stuff from is: Euclidean and Non-Euclidean Geometries: Development and History, Second Edition, by Marvin Jay Greenberg, published by WH Freeman and Company. Although it is not obvious, there is more than geometry to this book, and it is worth searching for.

Euclidean & Non-Euclidean Geometries Part 5: Axioms (Cont.) Continued from Part 4. I knock a glass candleholder off the shelf during the video, and the sound, while not very loud, might surprise you or your cat. I also knock something else off the ledge, but I don't remember what it was. EUCLID'S POSTULATE III. For every point O and every point A not equal to O there exists a circle with center O and radius OA. DEFINITION. The ray AB is the following set of points lying on the line AB: those points that belong to the segment AB and all points C such that B is between A and C. The ray AB is said to emanate from A and to be part of line AB. DEFINITION. Rays AB and AC are opposite if they are distinct, if they emanate from the same point A, and if they are part of the same line AB = AC. DEFINITION. An "angle with vertex A" is a point A together with two nonopposite rays AB and AC (called the sides of the angel) emanating from A. DEFINITION. If two angles BAD and CAD have a common side AD and the other two sides AB and AC form opposite rays, the angles are supplements of each other, or supplementary angles. DEFINITION. An angle BAD is a right angle if it has a supplementary angle to which it is congruent. EUCLID'S POSTULATE IV. All right angles are congruent to each other. DEFINITION. Two lines m and n are parallel if they do not intersect, ie, if no point lies on both of them. EUCLID'S POSTULATE V. (THE PARALLEL POSTULATE) For every line l (el) and for every point P that does not lie on l (el) there exists and unique line m through P ...
Euclidean & Non-Euclidean Geometries Part 2 How geometrical ideas originally were fashioned (without deductive logic), what the Greeks did to formalize geometry, and what some of our basic concepts will be. (Definitions, axioms or postulates, logic, theorems. Do they yield reality?) The two parallelograms that I drew don't use the same lengths for a and b. I also use the word equation when I really wish I had said formula. Hey, someone could take apart practically every sentence I said, but I just hope they are there when I get to the conclusion of the series to help me defend the big surprise. Because the board isn't clear, let me summarize here: EGYPTIANS: Definitions + Inspiration or experimentation = formulae which describe part of reality pertaining to interesting spacial relationships. GREEKS: Definitions + Minimal axioms + logic = Theorems Theorems + more logic = More theorems and a many more aspects of spacial relationships than can be empirically derived.

Geometries by Roger Zare This work was commissioned by Nathan Cole and the UBS Chamber Music Festival of Lexington ( ) and premiered on August 29, 2010 in the Fasig-Tipton Pavilion in Lexington, KY, with Alexander Fiterstein, clarinet; Nathan Cole, violin; Priscilla Lee, cello; and Alessio Bax, piano. I. Fractals II. Tangents Geometries is a two-movement work in which I use musical lines to imitate simple geometric ideas. The first movement, Fractals, begins structured as a hybrid of a fugue and a canon, where the theme is imitated simultaneously at the same pitch and at different pitches. It is first stated with the clarinet leading the right hand of the piano, then with the cello leading the left hand of the piano, and finally with the violin leading the right hand of the piano. Eventually, an acceleration in the texture yields a grand statement of the theme, with the violin soaring above. The material used in this movement is extremely economical, consisting of little more than the single theme, but through its saturation and recursion, it is able to spin itself into a wide variety of shapes and textures. The second movement, Tangents, is a "moto perpetuo" that traces single lines as they swoop and curve between the instruments. Often the piano will initiate a gesture that moves towards a single point where the clarinet, violin, and cello begin a new line, as if emerging from the piano. Complimenting the quickly flowing lines, a sweeping melody is revealed, first in the ...

Euclidean & Non-Euclidean Geometries Part 4: Axioms I bought twelve new markers thinking that I would use each of them for one video, and throw it away, so that I would always be writing with a nice, clear, legible black marker. So much for thinking. I may try chalk and a board next. For a list of the undefined terms, see Part 3. The following representations of axioms (or postulates) and definitions are flawed because typographical limitations prevent them from being displayed in a manner that mathematicians would approve. Suggestions welcome. EUCLID'S POSTULATE I. For every point P and for every point Q not equal to P there exists a unique line m that passes through P and Q. DEFINITION. Given two points A and B. The segment AB is the set whose members are the points A and B and all points that lie on the line AB and are between A and B. The two given points A and B are called the endpoints of the segment AB. EUCLID'S POSTULATE II. For every segment AB and for every segment CD there exists a unique point E such that B is between A and E and segment CD is congruent to segment BE. ("Any segment AB can be extended by a segment BE congruent to a given segment CD.") DEFINITION. Given two points O and A. The set of all points P such that segment OP is congruent to segment OA is called a circle with O as center, and each of the segments OP is called a radius of the circle. Continued in Part 5.
Root Geometries Structuring The Polyhedra-Copyright PStefanides 2011 ROOT GEOMETRIES STRUCTURING THE ICOSAHEDRON, THE OTHER BASIC POLYHEDRA AND THE GEOMETRIC FORMS RELATED TO THEM by PANAGIOTIS STEFANIDES Copyright PANAGIOTIS STEFANIDES Under "Root Geometries Structuring the Icosahedron, the other Basic Polyhedra and the Geometric Forms Related to them", we refer to the Basic Geometric Forms by which this theory contemplates the progressive mode of formation of the "Five Polyhedra" via Lines, Areas and Volumes. The Root Geometries are two triangles. A very Special one the SCALENE ORTHOGONAL TRIANGLE [ Srefanides interpretation of the Timaeic Most Beautiful Triangle] ] with sides [T^3], [T^2] and [T^1] in geometric ratio [T], where T is the Square Root of the Golden Ratio, and the ISOSCELES ORTHOGONAL TRIANGLE with sides [T], [T] and [T*SQRT(2)], WHERE T =SQRT [Φ] . Angle [Θ] of the Scalene equals to ArcTan [T], and the Specialty of this triangle is that the product of its Small side by its Hypotenuse is equal to the Square of its Big-ger side:[T]*[T^3] = [T^2]^2. Using a pair of the Special Scalene Triangle, and a pair of a Similar Triangle with sides 1,T and T^2 [Kepler's Triangle with sides 1, SQRT[Φ], and Φ] a Tetrahedron is obtained, basic to structuring the Great Pyramid Model. Splitting the Triangular Faceof the GP into two orthogonal co-planar triangles to form a Parallelogramme [with sides T and T^3] we have constructed the Basic Skeleton of the Icosahedron, since three such parallelograms, orthogon-al to each other, determine the ...

High-Quality Rendering of Varying Isosurfaces Smooth trivariate splines on uniform tetrahedral partitions are well suited for high-quality visualization of isosurfaces from scalar volumetric data. We propose a novel rendering approach based on spline patches with low total degree, for which ray-isosurface intersections are computed using effcient root finding algorithms. Smoothly varying surface normals are directly extracted from the underlying spline representation. Our approach is using a combined CUDA and graphics pipeline and yields two key advantages over previous work. First, we can interactively vary the isovalues since all required processing steps are performed on the GPU. Second, we employ instancing in order to reduce shader complexity and to minimize overall memory usage. In particular, this allows to compute the spline coeffcients on-the-fly in real-time on the GPU. rmatik.tu-
