Bowl a Strike with Wolfram System Modeler

Explore the contents of this article with a free Wolfram System Modeler trial. Bowling is a simple game that consists of a ball, 10 pins and a lane. You take the ball, come to the starting line, aim between pins 1 and 3 and throw the ball. You instinctively assume that the ball and the lane are perfect and expect the ball to go straight where you aimed.

Newick Trees, Proximity Resources and Accessions Analyzing SARS-CoV-2 Genetic Sequences

While working with SARS-CoV-2 genetic data in the Wolfram Data Repository, we noticed that there was frequently only a relative handful of differences compared with the overall size of the sequences. This allowed us a number of interesting opportunities for further processing.

John Snow & the Birth of Epidemiology Data Analysis & Visualization

In 1854, there was a major cholera outbreak in Soho, a neighborhood in London that Judith Summers described as full of “cow-sheds, animal droppings, slaughterhouses, grease-boiling dens and primitive, decaying sewers.” At the time, the cause of the outbreak was unknown because germ theory was still being developed and disease transmission was not well understood. Miasma theory was the dominant hypothesis, and it proposed that diseases, including cholera and the plague, were spread by foul gasses emitted from decomposing organic matter.

The Solution of the Zodiac Killer’s 340-Character Cipher

In 2020, Melbourne, Australia, had a 112-day lockdown of the entire city to help stop the spread of COVID-19. The wearing of masks was mandatory and we were limited to one hour a day of outside activity. Otherwise, we were stuck in our homes. This gave me lots of time to look into interesting problems I’d been putting off for years.

I was inspired by a YouTube video by David Oranchak, which looked at the Zodiac Killer’s 340-character cipher (Z340), which is pictured below. This cipher is considered one of the holy grails of cryptography, as at the time the cipher had resisted attacks for 50 years, so any attempts to find a solution were truly a moonshot.
