Scientific papers: innovation … or imitation?
Sometimes a paper comes out that has the seeds of a great idea that could lead to a whole new line of pioneering research. But, instead, nothing much happens, except imitative works that do not push the core idea forward at all. For example the McCulloch Pitts paper from 1943

I just stumbled across the binomial number system in Exercise 5.38 of Concrete Mathematics. The exercise asks the reader to show that every non-negative integer n can be written as and that the representation is unique if you require 0 ≤ a < b < c. The book calls this the binomial number

While it’s true that creativity is a key component of most ventures, having a practical playbook can often make the difference when navigating a complex problem or trying to master something that is completely new. Many of life’s more challenging endeavors don’t come with instructions or clear guidelines, leaving us

Casting out nines is a well-known way of finding the remainder when a number is divided by 9. You add all the digits of a number n. And if that number is bigger than 9, add all the digits of that number. You keep this up until you get a

Today, it would be hard to find someone who hasn’t had at least some experience with using generative AI for personal or professional use. Generative AI systems like ChatGPT, Bard, and Copilot rely on these prompts to interpret user intent and deliver the necessary results to make their model more
Read moreIterated logarithm
Logarithms give a way to describe large numbers compactly. But sometimes even the logarithm is a huge number, and it would be convenient to take the log again. And maybe again. For example, consider googolplex = 10googol where googol = 10100. (The name googol is older than “Google,” and in

With pressure mounting to move fast, reduce bias, and prove ROI on every new technical hire, traditional screening methods no longer cut it for companies that want to maintain a competitive hiring edge. Fortunately, technical assessment platforms and tools provide smarter, more objective ways to identify top developers. Even before

“The inverse of an approximation is an approximation of the inverse.” This statement is either obvious or really clever. Maybe both. Logs and exponents Let’s start with an example. For moderately small x, That means that near 1 (i.e. near 10 raised to a small number, The inverse of a
