Move to Global War: Germany (Part 2)
Question: What role did Germany play in the factors that led to World War 2?
This is the second part of the post which will cover the second point on the various incidents Nazi Germany was involved in up to the outbreak of WW2.
Before I delve into the various situations and conflicts Nazi Germany was involved in up to the outbreak of WW2,...
Move to Global War: Germany (Part 1)
Question: What role did Germany play in the factors that led to World War 2?
To avoid an overly long article, this question will be answered in two posts:
Firstly, Nazi Germany’s aggressive expansionist policies from 1933-1939.
Secondly, the various incidents Nazi Germany was involved in up to the outbreak of WW2, which is defined as the inv...
General Tips for History DBQ
Question: How to DBQ???
How much content do I need to know for DBQ? Can I bs my way through?? (ans: no.)
The interesting thing about the Document Based Question (DBQ) in History Paper 1 is it tests skills rather than solely content.
DBQ consists of 4 sources and 4 questions. Usually, three of the sources are texts and one is a cartoon.

Market Failure
Question: How to address a market failure question
Hallo everyone! I’m back with another econs article. Today I’m going to be talking about market failure, which I feel is one of the more difficult topics in unit 1 (barring theory of the firm for all the HL kiddos) and is widely tested in both paper 1 for the micro question and paper 2 in parts...
Tips for Integration by Parts
Hi y’all.
Here are some tips for tackling a few types of integrals. I’ll be focusing on integrals that you solve using Integration By Parts (IBP).
Here’s the formula for IBP:
$\int{u\frac{dv}{dx}}=uv-\int{v\frac{du}{dx}}$
This formula tells you that you have to differentiate one term (the term that you set as $v$) and you have to integrate o...

Energetics: Definitions of Enthalpy Change Reactions
Hello everyone! In this article I am going to group the main types of enthalpy change reactions to the best of my abilities, as well as summarise what they do and how to use them. Enthalpy change to put in layman terms, is the energy change to a system after any reaction. Hence if a system releases heat it is losing energy (hence exothermic and ...
Introduction to Ethics: Morality and Ethics
This is Part 1 of 4 of the AOK Guide for Ethics
Ethics is an AOK which most people wouldn’t touch with a 10-foot pole. Hopefully, this guide will make it more ACcessible (wink) to people who think ethics is interesting but just can’t wrap their heads around it.
Morality
For any action or moral agent (ie. a being capable of moral action such as...
Naming Organic Reactions
What is the difference between an addition or a substitution reaction in Organic chemistry?
For those who have just started learning organic chemistry, many of you may be intimidated by the many long confusing names all the reaction has, like “Nucleophilic Substitution” or “Electrophilic Addition” and confused as to what they all actually mean....
Meursault doesn’t play the game
Question: In what way is Meursault the outsider?
Hi :)
Today I’ll be analysing the characterisation of Meursault as an outsider, and the implications it has, where society ostracises and condemns him for being different. (There are a lot of points on how Meursault is different, so I’ll just state the main points and 1 quote + explanation)
Meu...
On Force Carriers and the Higgs Boson
Question: Hi I have a question about force carriers in atomic physics, is there a definition of what they are and what’s the difference between them and the Higgs Boson Particles?
Hi y’all.
According to Wikipedia: In particle physics, a gauge boson is a force carrier, a bosonic particle that carries any of the fundamental interactions of natur...
$S_N1$ vs $S_N2$ reaction mechanism
What is the difference between $S_N1$ and $S_N2$ reaction mechanism in Nucleophilic substitution?
Hello, just to preface this post the question given is rather general and conceptual, and as such the post would be quite long but I will try to break it up neatly as much as I can. In an attempt to stay focused, I may gloss over certain concepts w...
Stoichiometry Guide
Why do we do stoichiometry? If we want to do any quantitative chemistry (that is, involving numbers and stuff), we need to know how much of a reactant a reaction uses and how much of a product is formed. Stoichiometry is the foundation of all mathematical calculations regarding chemistry and chemical equations.
Step 1: Balance equation and find...
Determining Molecular Geometry
Question: How do we determine the molecular geometry of a given molecule?
The core idea of molecular geometry is that electron pairs (whether bonding pairs or lone pairs) don’t like each other. They want to be as far apart as they possibly can from each other.
The way I like to think about it, is to combine both lone pairs and bonding location...
Role of valves in allowing the heart to pump blood in a single direction
Question: How do different valves in the heart allow blood to flow in a single direction?
Hey y’all!
The heart is made up of various parts that allow it to function as an efficient pump but one of the most crucial parts are the 4 sets of valves that allow blood to flow in a single direction. These valves are a lot like the valves found in the ...
Examine the methods used in the emergence of 1 authoritarian state
Question: How do I examine the methods used in the emergence of authoritarian states?
This essay question applies to both HL and SL history students. The question would appear in Paper 2 under the topic “Authoritarian states (20th century).”
The first thing to do when writing any history essay is to understand the demands of the question. In ...
Growing towards development
Question: How does economic growth lead to economic development?
Hallo everybody !!
I know many of y’all may be unclear on how to tackle questions related to development economics, which is one of the 2 topics tested for paper 2 (DRQ) as the usual lectures could not be held due to COIVD. So today I’m just gonna give some general guidelines on ...
Regarding Electron flow in circuits
Question: Regarding Electron flow in circuits
Hi y’all.
I’m addressing a misconception that I feel many people (even some year 6 students) have about circuits.
We are told that “Electrons flow through the wires in a circuit, from the negative terminal of the battery to the positive terminal of the battery”
So intuitively it’s easy to think o...
Why is ozone non-polar?
Why does Ozone have a higher boiling point than oxygen? Why is it not for because $O_3$ is polar and has dipole-dipole forces while $O_2$ is non polar and only has London dispersion forces.
Based on the question, I feel that the misconception here is that O$_3$ is polar because of two reasons, its “bent” molecular geometry and the charges on th...
How does bonding between 2 or more elements work?
How does bonding work? How do you identify the type of bond in a compound if there are more than three elements?
I think what’s Important here is that what specifically is a bond. A bond is a force of attraction between two atoms in the periodic table, but the type of attraction varies from bond to bond. So, if there are more than two atoms i...
How does electronegativity work?
As we all know, elements all have a nucleus and electrons around it. And in a covalent bond, a pair of electrons is shared between two elements, with electrostatic forces of attraction between the positively charged nuclei and the shared pair of electrons. However, in order to grasp the concept of electronegativity, one must think of electrons a...
Organic Chemistry Study Tips
Step 1: Familiarise yourself with reaction mechanisms.
There are only a few generic kinds of organic reactions tested (at least for IB), and hence I find it easier to memorise the general mechanism behind the different reactions. This would give you a deeper understanding of the steps and the factors which lead up to the final product. For IB st...
Acid Buffer
Question: How does an Acid Buffer work?
An acidic buffer is a solution which is able to maintain the pH of the solution (at an acidic level) even if small amounts of base or acid is added.
In every acid molecule, there is a hydrogen atom as part of the molecule. When dissolved in water, the acid molecule would dissociate, forming a $H_3O^+$ ...
