How Does a Calculator Find Sine of an Angle?
Ever wonder how you can calculate sine of an angle without a scientific calculator? Here is a brief introduction on finding the answer with only adding, subtracting, multiplying, and dividing.
Chemistry How To: Titration
In order to determine the content in an unknown solution, chemist would use a method called titration. Not only is it common in laboratories, it appears on tests too! Follow these 3 steps to understand every titration process!
Monty Hall Problem
The Monty Hall Problem is a famous problem that has been around for decades and originated from an American game show. This brain teaser was first solved by Steve Selvin and later Marilyn vos Savant, but many have debated whether their answer is mathematically accurate.

In this article, we will examine how resonance works. Resonance is a very powerful phenomenon in nature, be it climate change to collapsing bridge.
Devices: form and function
Devices move across genres—there are poetic devices, literary devices and rhetorical devices—but, no matter their genre or their names, their form (what they look like) remains constant and their function (what they do) will always be variable. Knowing this about devices makes language analysis all the more easier and interesting. Let me show you.

Golden Ratio: Math or Art?
The Golden Ratio is a Mathematical concept that dates back centuries and has been widely studied by many renowned mathematicians. Over the course of time, it is no longer just applied in Math but can now be seen in virtually all fields, especially the Arts.
Setting your Sights on Success
Many students approach Paper 1 with only one goal in mind, analysing the text’s stylistic devices. But there’s more to it. Fifty-percent of the task is analysing the text’s structural features. So, come exam day, if you're analysing for both structure and style, you're sure to increase your score.
How to Use Chi Square Test on Raw Data
In any experiment, raw data has to be converted to something scientifically significant. One of the ways being taught in IB is chi-square, which is confusing to many students. Here is a 4-step example that turns raw data into a conclusion.
