3D Structure and Bonding: Crash Course Organic Chemistry #4

The organic molecules that make up life on Earth are more than just the 2-D structures we’ve been drawing so far. Molecules have 3-D shapes that help us understand what they can do. In this episode of Crash Course Organic Chemistry, we’ll learn how orbital hybridization and valence bond theory can help us explain 3D molecular structures and about constitutional and geometric isomers.

    "The thinking mind must constantly be stirred by new experience and by adaptation to new experience and new understanding in order to be vital and capable of learning. It is like stirring concrete. If you do not keep stirring it and adding water and new things to it, it hardens. And once it hardens, it can only be broken. People who are learning and living The Way of Knowledge are constantly being renewed and refreshed because they are close to life, and they are close to Knowledge. Their thoughts change, grow and evolve. Their ideas change, grow and evolve. Their conclusions change, grow and evolve. They can do this because there is something greater. There is Knowledge, the dynamic force of life within you, within the world and within the Greater Community as well. Knowledge brings you to the edge of life where you have to learn and adapt, communicate and contribute. This keeps you young, alive and close to the heart of life. Your mind, then, becomes constantly relevant to the present and is able to prepare for the future." This is a quote from a book titled Living the Way of Knowledge. For those who wish to educate themselves about the human mind, about the deeper spiritual intelligence within each person, about the meaning and purpose of life, about the great changes happening in the world and even greater yet to come, about the Greater Community of intelligent life in the universe, you can read this book free online, among many others at *NewMessage org*

    The animators of these contents deserve a big salute but the teachers a middle finger!!!They are just telling who did this ,when he did this most of the time giving less time to the concept what we actually need.They have been working on these things for their entire life but almost all of us watching this are new to this.I understand this stuff,but not deeply ,because they just introduce unrelevant things,this topic was to be corely focused how molecules actually look at a deeper level,the animations are the only reasons to watch these videos .Einstien said,"If you cant explain the thing you know to a 6 year old,then you are actually either showing off or not getting yourelf". These people have understood no doubt for their life is just rumbling around these things and they fall into the second category of einstien's saying
