Learn you Galois Fields for Great Good (00) Navigation | first | next Introduction This is the introduction to a series on Abstract Algebra. In particular, our focus will be on Galois Fields (also known as Finite Fields) and their applications in Computer Science.

Drinks in glass bottles contain more microplastics than those in other container

news.ycombinator.com Unknown 2025-09-10 00:01:34

The aim of the ANSES study was to determine the level of microplastic contamination in drinks such as water, soda, iced tea, wine and beer; it also sought to establish the impact of their containers on this level. For most of the drinks studied, the level of microplastics was found to be higher in glass bottles than in other containers. For example, on average, in glass bottles of cola, lemonade, iced tea and beer, there were around 100 microplastic particles per litre. This number was five to 5

Cracovians: The Twisted Twins of Matrices

news.ycombinator.com Unknown 2025-09-09 22:35:05

Linear algebra is typically explained using matrices. But matrix theory is just one possible perspective. Below, I describe an alternative approach to linear algebra. Tadeusz Banachiewicz (1882–1954), a Polish astronomer living in Krakow, was passionate about calculating machines. From the 1920s, Banachiewicz developed a method for computations on tables of numbers, which was particularly easy to perform with arithmometers. In honor of Krakow, Banachiewicz named these computational objects crac

The golden Trump Phone is almost certainly not made in the US

Not content with a real estate empire and the presidency of the United States, the Trump family is wading into the phone wars like it's 2011 with a shiny gold monstrosity called the T1, the marketing of which leans extensively on the narrowest idea of patriotism. Beyond the immediate question — why do this, like, at all? — the T1 invites a question that's perhaps easier to interrogate: How can any modern smartphone claim to be made in the US?
