Estimate the Area of an Image Segment
Hi there! I am (Kirill Vasin) working as a spectroscopist. We shine light through the samples and estimate how much is absorbed and at which frequency. In this case, it is quite crucial to know the light spot, which is collimated by a speci...

About
As an open-source initiative, our mission is to bring the power of Wolfram Language computation—traditionally associated with heavyweight closed commercial tools—into a portable, browser-based environment. Developed through the collective effort of physicists and programmers this freeware notebook environment helps in solving real-world scientific challenges, teach students complex concepts from science more intuitively, and explore mathematics and computational thinking in a more interactive and accessible way using symbolic programming paradigm.
WLJS Notebook is the first open-source solution to feature true 2D math input combined with powerful syntax sugar and the fastest granular interactive evaluation engine, making it ideal for advanced mathematical workflows, scientific computing, and data exploration.
