In this article we walk through the history of π and learn a bit of Python programming along the way. https://cienciaprogramada.com/2022/04/mass-balance-python-sympy/ Wed, 20 Apr 2022 00:00:00 +0000 contato[@]cienciaprogramada.com.br (Francisco Bustamante) https://cienciaprogramada.com/2022/04/mass-balance-python-sympy/ Mass balance equations are important for practically all calculations in solving chemical engineering problems. In this article, we will solve two mass balance problems using the SymPy library and review some important principles. https://cienciaprogramada.com/2022/02/top-3-python-libraries-chemistry/ Mon, 07 Feb 2022 00:00:00 +0000 contato[@]cienciaprogramada.com.br (Francisco Bustamante) https://cienciaprogramada.com/2022/02/top-3-python-libraries-chemistry/ In this article, we explore 3 chemistry libraries available for the Python language, showing how they are useful in the daily routine of chemistry professionals and students. https://cienciaprogramada.com/2020/12/studying-atmosphere-python/ Sat, 05 Dec 2020 00:00:00 +0000 contato[@]cienciaprogramada.com.br (Francisco Bustamante) https://cienciaprogramada.com/2020/12/studying-atmosphere-python/ Colorless, made of invisible constituents, and odorless (we hope!). We often forget that we are surrounded by the gases that make up our atmosphere. In this article, we will see how to easily get a list of the main constituents of air with Python and web scraping. We will also do some calculations, such as density and mean molar mass, and, of course, present everything in spectacular plots. https://cienciaprogramada.com/2020/08/nasa-loses-millions-unit-errors/ Thu, 20 Aug 2020 00:00:00 +0000 contato[@]cienciaprogramada.com.br (Francisco Bustamante) https://cienciaprogramada.com/2020/08/nasa-loses-millions-unit-errors/ In this article we will see how NASA has lost multimillion-dollar projects to simple unit conversion errors. We will also see which system of units took humans to the Moon in the Apollo Program, by looking at the source code of the onboard computer. https://cienciaprogramada.com/2020/08/unit-conversion-error-plane/ Sat, 15 Aug 2020 00:00:00 +0000 contato[@]cienciaprogramada.com.br (Francisco Bustamante) https://cienciaprogramada.com/2020/08/unit-conversion-error-plane/ How can a plane run out of fuel at 12 km of altitude? Today’s article is about a Boeing that became a 100-ton-plus “glider” and how it all happened because of a simple unit conversion error.
