Recently, a proof of the collatz conjecture was presented. While the proof seems convincing, it does contain a critical flaw.

The Collatz Conjecture: A Simple Proof
The collatz conjecture, first proposed in 1937 by Lothar Collatz, is a problem that seems simple, but has confounded mathematicians, who have been unable to prove or disprove it, for decades. So, without further ado, here is a simple proof of the collatz conjecture.
3D Printing a Better Black and Tan Part 6b: Beyond The Second Layer
In the ongoing saga of designing siphons for making layered drinks, we have previously presented the Mk II mini siphon for making two-layer shots, which works quite well. However, the nature of the self-starting siphon means that the volume of each pour is fixed.
But what if there were a way to modify the volume of the pour so a three-layer shot could be made?
3D Printing a Better Black and Tan Part 6: The Next Generation
Since our previous attempts at 3D printing a siphon to make a layered beverage, there have many advancements in the world of 3D printing, the most significant of which is the release of the Prusa XL with its multiple print heads. So, we figured it was high time to try printing some new siphons with newer technologies.
Here we try to make a new, hopefully better, version of the mini siphon for making layered shots.
Flawed Reasoning Awareness Through Gamification
Reading through comments on social media is often infuriating due to flawed reasoning that allows people to believe false claims or reach false conclusions. Since gamification has been used to raise awareness of other topics, why not flawed reasoning?
The 1.676hp Microwave Saga: Part 4
As luck would have it, a friend recently replaced their microwave and lent us their old 1100W microwave for sciencing, before proper disposal. Until now, the focus of our ongoing series on understanding the power output of a new 1250W microwave has been based on estimating the output of an 1100W microwave. In this installment we can see how accurate those estimates were.

The 1.676hp Microwave Saga: Part 3
In our ongoing series attempting to determine which power level on a new 1250W microwave is closest to 1100W, we now take a closer look at the oddities of power levels P1 and P2.

The 1.676hp Microwave Saga: Part 2
While attempting to determine which power level on a new 1250W microwave corresponds to 1100W, some of the data collected was a bit odd. So we needed to take a closer look to see what was going on. Here we examine power levels P9 and P10.

The 1.676hp Microwave Saga: Part 1
After over two decades of faithful service, our trusty 1100W microwave recently failed, giving us the opportunity to upgrade to a more modern 1250W microwave with an inverter. Unfortunately the extra power has caused some problems in estimating power levels and cook times, as most instructions are based on an 1100W model.

A-mazing Cubes II: The Flattening
After a longer than expected delay, MazeCubeGenerator now has the ability to produce 3D models that should be easier to print on a typical 3D printer.
