Symmetries of Bravais Latticings

Each Bravais lattice has a different set of T. G is measured in units of length. The symmetry properties of the lattices can be classified.

The rectangular lattice in Figure 1 has reflection lines which can be seen through the horizontal and vertical rows of points. There are additional symmetry elements between the lattice points shown in Figure 2. Not all regular array of points are lattices because they must have the same environment.

In one dimensions there is only one lattice that has an array of equally-spaced points. The relative magnitudes of the translation vectors and angle between them can be used to group the lattices of Figure 4. A periodic physical system can be described as a lattice with repeating units attached to each point.

The basis may be a single atom, a molecule or a larger assembly. The space group that characterizes the structure is the result of the lattice and basis symmetries. One expects a larger number of space groups than lattices since bases with different symmetries can be attached to a lattice.

There are 17 space groups in two dimensions. The International Tables for X-ray Crystallography describes the combined symmetries of the 14 Bravais lattices and all possible bases, which lead to 230 space groups in three dimensions. The classification of periodic structures as members of specific space groups is important in predicting properties, such as allowed reflections in X-ray diffraction and allowed vibrational modes in optical spectroscopy.

Directed Line Segments

A directed line segment is a segment with an arrow at one end that shows the direction of movement. A directed line segment has a specific length.

Translation Math

A figure can be moved upward, downward, left, right, or anywhere in the coordinate system using translation. The mini-lesson was focused on translation math. The journey of translation in math starts with a student already knowing what they are talking about and then they use their creativity to create a new idea. It is easy to grasp and will stay with them forever, because it is done in a way that is easy to understand.

Linear translations

The points in the object are moved in a straight line. The size, shape and orientation of the image are the same as the original object. The object and image are facing the same direction. A translation can be represented by a column matrix or column vector where a number of units to move right or left along the x- axis and a number of units to move up or down along the y- axis are all shown.

The camera ToClipMatrix is GLSLsmat4

The matrix cameraToClipMatrix has the same properties as a GLSL mat4. The zero-based column of the matrix is returned as a vec4 if the mat4 is included in the array. A diagonal matrix is a type of matrix that is constructed using only a single value.

There is a matrix with zeros except for the diagonal from the upper- left to the lower-right. The value will be passed to the constructor. A diagonal matrix with 1 as the value is called an identity matrix.

Word vectors and word2vec model

Word vectors are numbers that represent the meaning of a word. We'll come back to it a bit, but for now, that's not very clear. It is useful to consider why word vectors are considered a leap forward from traditional representations of words.

The word's distributed weight is represented by the numbers in the word. The meaning of each of the dimensions is represented by the word's numerical weight on that dimensions and the connection it has to that meaning. The word's meaning is embedded across the dimensions of the vector.

The words are mapped in the space. Notice how close "cat" and "dog" are to "pet", how clustered "elephant" and "lion" are, and how descriptive words also cluster together. It is useful to discuss the workings of the word2vec model, which is popular and useful.

The magnitude of a vector

A quantity with both magnitude and direction is called a vector. A direction component along with the magnitude helps to determine the position of one point relative to the other in a vector quantity. You can learn more about the subject here.

A number is a quantity that describes the magnitude of an object or the position of an object with respect to another point. It is also known as a geometric or spatial vector. The magnitude of a vector is the length of the directed line and the angle at which the vector is inclined is what is shown in mathematics.
