Homotopic, Enantiotopic, Diastereotopic, and Heterotopic Protons
In doing NMR spectroscopy, we must be able to predict chemical shifts for a variety of protons. When comparing specific pairs of protons, we can assign them a few different relationships, those being homotopic, enantiotopic, diasteretopic, and heterotopic. Let's see what these words mean a

Homogeneous vs Heterogeneous Catalysts - Basic Introduction
This video provides a basic introduction into homogeneous and heterogeneous catalysts. A Homogeneous catalyst exists in the same phase as the reactants and products. A heterogeneous catalyst exists in a different phase as the reactants and products. New Chemistry Video Playlist: https

Introduction to Homotopy Theory- PART 1: UNIVERSAL CONSTRUCTIONS
The goal of this series is to develop homotopy theory from a categorical perspective, alongside the theory of model categories. We do this with the hope of eventually developing stable homotopy theory, a personal goal a passion of mine. I'm going to follow nLab's notes, but I hope to add t

Homogeneous and Heterogeneous Mixtures Examples, Classification of Matter, Chemistry
This chemistry video tutorial explains the difference between homogeneous and heterogeneous mixtures within the subtopic of the classification of matter. It contains plenty of examples. Homogeneous mixtures have constant composition. Salt water is a homogeneous mixture - it has one visi

Homomorphisms in abstract algebra
In this video we add some more definition to our toolbox before we go any further in our study into group theory and abstract algebra. The definition at hand is the homomorphism. A homomorphism is a function that maps the elements for one group to another whilst maintaining their structu

Stereospecificity vs. Stereoselectivity and Regiospecificity vs. Regioselectivity
Many organic chemistry students think that specificity and selectivity are essentially synonymous when describing the potential products of a chemical reaction. But this is not true! They have separate meanings and imply different things, so let's make sure we know how this works when appl

Divisibility, Prime Numbers, and Prime Factorization
Now that we understand division, we can talk about divisibility. A number is divisible by another if their quotient is a whole number. The smaller number is a factor of the larger one, but are there numbers with no factors at all? There's some pretty surprising stuff in this one! Watch th

Understanding the Causal Impact of Climate on Human Conflict
Scholars, writers, and policymakers from Shakespeare to Obama have noted linkages between the physical environment and human behavior toward one another. Professor Marshall Burke synthesizes a growing cottage industry of research that seeks to quantitatively measure how changes in climate

A Level Chemistry Revision "Heterogeneous and Homogeneous Catalysts"
In this video, we look at heterogeneous and homogeneous catalysts. First we explore heterogeneous catalysts, using the Haber process as an example. We look at how heterogeneous catalysts work in terms of adsorption and desorption. We then look at homogeneous catalysts using the reactions o

Causal Behavioral Modeling Framework - Discrete Choice Modeling of Consumer Demand
There are increasing demands for "causal ML models" of the agent behaviors, which enable us to unbox the complex black-box models and make inferences or do proper counterfactual simulations. Many applications (especially in Marketing) intrinsically call for measurement of the causal impact

Assessing the Direct and Spillover Effects of Shocks to Refugee Remittances

Homomorphisms in abstract algebra examples
Yesterday we took a look at the definition of a homomorphism. In today's lecture I want to show you a couple of example of homomorphisms. One example gives us a group, but I take the time to prove that it is a group just to remind ourselves of the properties of a group. In this video th
