Welcome to part 4 of my series on cryptography! After taking an in-depth look into ciphers in the previous two posts, now it's time to delve into the other big category of cryptographic methods. So, this week's post is going to be about cryptographic … [Continue reading]

## Vigenère and the Age of Polyalphabetic Ciphers

In this week's post, I'm going to introduce you to the world of polyalphabetic substitution ciphers. And to the most famous cipher from this category: the Vigenère cipher. This post is part of my series Cryptography: Historical Intro & … [Continue reading]

## The Column and Caesar Ciphers: Ancient Cryptography

Today, I'm going to introduce two ciphers from the dawn of cryptography: the column cipher and the Caesar cipher. These ciphers illustrate some of the first human ideas in the direction of cryptographic thought. This post is part of my series … [Continue reading]

## Cryptography: Historical Introduction & Combinatoric Analysis (Series)

Hi everyone, and welcome to my series on cryptography! Initially, I started writing this as a single post, but as I was planning what I wanted to include, and seeing how long it would become, I decided it's best to split it into separate posts. … [Continue reading]

## Discrete Probability Distributions: Overview (Series)

In my previous two posts I sketched the frame of the big picture around probability distributions. In my introductory post I gave some intuition about the general concept and talked about the two major kinds: discrete and continuous distributions. … [Continue reading]

## Mean and Variance of Probability Distributions

In my previous post I introduced you to probability distributions. In short, a probability distribution is simply taking the whole probability mass of a random variable and distributing it across its possible outcomes. Since every random variable … [Continue reading]
