Theorem and Algorithm Lab

Core STEM lab for Pythagoras, Kruskal MST, Einstein mass-energy, and Gantt planning, with quick links to dedicated Math, Physics, Processor, and Science Labs.

Open tool →

Pythagorean Theorem Calculator

Calculate the hypotenuse or missing side of any right triangle using the Pythagorean theorem a² + b² = c². Free, private, browser-based.

Open tool →

Kruskal MST Visualizer

Visualize Kruskal's minimum spanning tree algorithm step by step. Add weighted edges, watch Union-Find detect cycles, and see the MST build in real time.

Open tool →

Einstein E=mc² Calculator

Calculate mass-energy equivalence using Einstein's E=mc². Enter mass in kilograms to find energy in joules, or reverse. Browser-based and private.

Open tool →

Gantt Chart Planner

Create Gantt chart project timelines in your browser. Add tasks with start dates and durations, visualize overlaps, and identify the critical path.
