  • 1-Intro I9:36

    Introduction to the course ,

    Please have a look at the Resources before purchasing the course . It is an open source course by prof. Rajesh Prasad .

    You might find what you were looking for in them and not have to buy the course .

    But of course the style of teaching is completely different in this course , in addition to using new tools of illustration here , Like AUTOCAD .

    I hope you will find what you hoped for in this course .


    **NOTE :

    You might need to speed up the videos a little bit ,as I  am talking somewhat slowly .


    Best wishes and Happy Learning !  .

  • 2-Intro II12:56

    Explore the microscopic crystal structure, distinguishing crystalline and amorphous solids, with domains and grains that govern optical and mechanical properties, and introduce x-ray diffraction as a tool.

  • 3-Lattice I12:48

    Explore how identical spheres can fill space with translational symmetry, defining a lattice and distinguishing true lattices from non-lattice arrangements through the concept of identical environments.

  • 4-Lattice II18:52
  • 5-1-Crystal VS Lattice13:18

    Distinguish crystals from lattices by framing crystals as a lattice with a basis or motive, where the lattice provides repeating positions and the basis defines the atoms.

  • 5-2-Crystal VS Lattice II11:04
  • 6-1-Unit Cell I - Intro15:27

    Understand how translation symmetry builds a lattice from a unit cell, using basis vectors a and b and the angle alpha to generate the whole lattice.

  • 6-2-Unit Cell II - Uniqueness9:42
  • 6-3-Unit Cell III - choice criteria9:39

    Identify and compare primitive and non-primitive unit cells, prioritizing symmetry as the primary criterion, then consider size and convention to classify lattices and define lattice parameters.

  • 6-4-Unit Cell III -3D5:43
  • 7-1-Lattices Classification I13:17

    Explore how lattices are classified by basic shapes and additive centers, from 2D five lattice types to 3D fourteen lattices, using primitive, body-centered, face-centered, and base-centered arrangements.

  • 7-2-Lattices Classification II -example13:13

    Explore crystal systems and the classification of lattices, detailing primitive, body-centered, face-centered, and end-centered lattices among the 14 lattice types, and how to identify units to generate a full crystal.

  • 7-3-Quiz-Edge-Centred4:20
  • 8-1-Messing Lattices5:36
  • 8-2-UC-choice-example14:23

Requirements

  • Basic Geometry of Simple Shapes , ex: square, parallelogram, cube, parallelepiped.
  • Basics of Vectors (Not crucial)

Description

Materials Science and Engineering  ,

An important field of science that has always had a strong effect on the evolution of civilizations and how advanced they were .

Being a measure of humanity's capability, knowledge of materials was used to mark ages , we say "stone age"... . As time passes, our knowledge became more comprehensive and accurate about the different types of materials and their properties ,

So advanced that we can now produce new materials, which is what we call materials engineering. And That's why I present this course to you .

One of the fields that I study passionately is materials science, because it is a crucial prerequisite for designing any structure or machine . This course "Crystallography" is an introductory course for materials science, starting from the very basics ,designed for high school students or college students in early years , who are interested to know how do solid materials look like at the deepest levels of the atomic scale . how are atoms oriented together, and how could we describe this orientation.


In this course we'll not follow the traditional way of teaching . It is meant to be a comprehensive course covering a large group of topics regarding crystalline solids , especially steels ceramics and polymers . As they are the most commonly used materials in manufacturing.  We will study these topics in full detail ,and move slowly but surely towards building a strong foundation for future studies in engineering fields .

This is the first batch of the course covering the following topics :

- Crystal structure and its different levels

- 2d & 3d Lattices -unit cells - symmetry in 2d &3d , 

- Square lattice as an example of 2d lattices 

- Cubic lattice as an example of 3d lattices . 


Special illustration methods are used to make sure the information is properly delivered .

This course consists of : 4:47 hours , 31 videos, average 8.7 minutes per video .

And remember that you have a 30 day money back guarantee, if you are not totally satisfied with the course.   Looking forward to your suggestions and Support and,

See you in the course.

Who this course is for:

  • High School Students .
  • College Students in their early years.
  • Interested people about understanding Materials.
