Four Temperaments Scale & Initial Thoughts

Hey all! Since I'm a bit of the reflective type, I decided to take the Four Temperaments personality test today. Here are my results, and my thoughts on the system. My main temperament is Melancholic, followed by Sanguine, and then Phlegmatic, and finally Choleric. I've included the results below so you can get a better … Continue reading Four Temperaments Scale & Initial Thoughts

Acids & Bases (Basic Principles Of)

Hello hello! We're coming into the last stretch of the semester, with finals week starting this very Friday for us (yoohoo, hi Wellesley students!) So, that leaves me with one more unit of chemistry that I want to cover, which is.... acids and bases! Go ahead and check out last time's crash course on Electrochemistry if you … Continue reading Acids & Bases (Basic Principles Of)

Electrochemistry

Thrilled you're here. If you haven't already, I would recommend checking out some of my previous crash courses on Chemistry, such as Chemical Equilibrium from last week. Electrochemistry is the study of redox reactions in the production of (1) electrical currents from spontaneous chemical reactions, and (2) non-spontaneous chemical changes by the use of electrical currents. There … Continue reading Electrochemistry

Chemical Equilibrium

Thanks for joining me again for the newest installment of my crash course series on Chemistry! In case you missed it, last time I wrote on Spontaneity, Entropy, & Free Energy, and today's lesson will be on chemical equilibrium! From last time, we know that If we take the antilogarithm, we get From this equation we … Continue reading Chemical Equilibrium

An Initiation to Chemical Kinetics

In chemical reactions, we seek to answer two main questions: How can we know whether a reaction will be spontaneous? Once started, how fast will the reaction proceed? The laws of thermodynamics help us answer (1). Chemical kinetics help us answer (2). The energy difference between products (C+D) and reactants (A+B) pertains to thermodynamics. The … Continue reading An Initiation to Chemical Kinetics

Chemical Bonds, Especially Covalent Ones

I'm back again with my crash course series on chemistry! Chemical bonds are strong links between atoms within a molecule and are really hard to break. Between molecules, there can be attractive forces too, but these are much weaker and not considered chemical bonds. Today we will be seeing how the shapes of atomic orbitals … Continue reading Chemical Bonds, Especially Covalent Ones

A look at “many-electron atoms”

Last time, when talking about quantum mechanics, we used Hydrogen as our prime example. That's because Schrödinger's equation for H can be exactly solved, but that's not so for the other elements on the periodic table. Any atom that contains two or more electrons is called a many-electron atom. This excludes H, He+, Li2+, etc. … Continue reading A look at “many-electron atoms”

Intro to Nuclear Chemistry

Hey there. I'm assuming you know a little bit about what atoms, molecules, and ions are, and you might know a bit of stoichiometry and the types of chemical reactions that happen in our crazy big/little world, and you're probably reading this because either you (a) are taking a course covering this topic, (b) you … Continue reading Intro to Nuclear Chemistry

An Introduction to the Tropical Marine Environment

My last post in my "Learn Something!" column, An Introduction to Neotropical Birds, pretty much wrapped up what my series on rainforest ecology had to say. Today I'll be beginning a new series on reef ecology, which is also very exciting and is something I'm very passionate about. The importance of coral reefs When we talk about … Continue reading An Introduction to the Tropical Marine Environment

An Introduction to Neotropical Birds

To continue my series on rainforest ecology, let's take a look at the birds that live in this fascinating area.   Evolution Neotropical birds were evolved from dinosaurs from possibly up to 125 million years ago, having both inherited reptile features and feathers. From there, different birds, for example the chaffinches and the bramblings, were separated, … Continue reading An Introduction to Neotropical Birds
