Welcome to the01 / 09
Königsberger Bridges Institute
We build communities that apply practical STEM to solve real-world problems.
Our name comes from a famous example of exactly that.

Königsberg · 173602 / 09
Seven bridges. One question.
The river Pregel divided the city into four pieces of land, joined by seven bridges. Could anyone walk through the city and cross every bridge exactly once?
Euler's method03 / 09
Land becomes a point. A bridge becomes a line.
In 1736, Leonhard Euler set aside streets, distances, and shapes. Only the connections remained. This was the start of graph theory.
Euler's answer04 / 09
Every point is odd. No such walk exists.
A walk that crosses every bridge once allows at most two points with an odd number of bridges. Königsberg had four of these points, thus proving mission impossible.
Why our name05 / 09
Practical STEM for a real-world problem.
Euler took a question from everyday life and answered it with mathematics. It was a fun problem, but a real one.
That is what our communities do: they apply practical STEM to solve real-world problems.
Our vision06 / 09
Prepare humanity for unknown unknowns through continuous innovation.
Unknown unknowns are the challenges we cannot yet see. They may be bigger than the biggest problems we face today, such as climate change, and some could threaten the survival of humanity.
Our mission07 / 09
Build communities of competent, curious, kind, and fun people.
We uplift each other and our society towards our vision. It is a journey that never ends, and a rewarding and meaningful one.

KBI joins Euler's city as a new point, with four new bridges. Now every point has an even number of bridges.
Every point is now even09 / 09
Now the walk exists.
One walk crosses every bridge exactly once. Build the next bridge with us for a better tomorrow.
