The Quotient Rule: Proof

This video explains and proves the quotient rule as seen in A Level mathematics and beyond. I do "borrow" a result that I don't prove, so this proof lacks a little rigour, but I'm hoping the trade-off is the video will be easier to understand. Introduction:

The Contrapositive and Proof by Contrapositive

The contrapositive is a powerful tool that can be used to prove various mathematical statements. It is most useful when a direct proof is awkward or impossible, and - if it can be used - is often a much more elegant method that employing proof by contradiction. #proof #contrapositive #proo

Bitcoin Q&A: Directed Acyclic Graphs (DAGs) and IOTA

What is your opinion on directed acyclic graphs (DAGs) and whether they can achieve the same level of decentralisation, security, and censorship resistance? DAGs are not vaporware, but the cryptocurrency projects using them mostly employ proof-of-stake (PoS) or proof-of-authority consensus

"Blockchain" or Bitcoin: Understanding the Differences

In this talk, Andreas explores the rise of the term "blockchain" as a counterweight to bitcoin. The term blockchain does not provide a definition, as it has been diluted to be meaningless. Saying "blockchain" simply invites questions, such as "what is the consensus algorithm". Meanwhile, b
