🌟Highlights

My name is Chris van Tienhoven, and I live in the Netherlands.

I was born in 1950 in a quiet village nestled at the foot of a dike, where the river Lek gently traced the landscape. I spent my youth in Rotterdam, surrounded by the energy of the harbours, before moving to Leiden to study Mathematics—with a subsidiary focus on Computer Science—at Leiden University, the oldest in the country.

After graduating in 1975, I began a long and varied career in IT and automation, working as a programmer, analyst, consultant, and project manager. In 1994, I took a creative turn and became the owner and director of a company specializing in graphic design and printing. Since 2008, I’ve shifted my focus toward family, personal exploration, and my lifelong fascination with mathematics.

I’m happily married and a proud father. My family is my anchor—and my compass.

🧠 Interests & Hobbies

• Mathematics: Especially geometry and algebra. I’ve always been captivated by the elegant structures of lines, points, and curves, and I enjoy pushing the boundaries of scientific understanding.
• History: With a particular interest in prehistory and ancient civilizations.
• Music: I play guitar and find joy in musical expression, especially in the sounds of the sixties.
• Mountains & Hiking: Nature inspires me. I regularly seek out challenges:
  • 2001: Climbed Mont Blanc (4,800 m)
  • 2017: Hiked from Saint-Jean-Pied-de-Port to Finisterre (900 km in 37 Days)
  • 2022/2023: Hiked from Utrecht to Santiago de Compostela (2,800 km in 120 Days)

🧭Philosophy

I’m drawn to the intersection of logic, spirituality, and philosophy. My journey has moved from religious belief to spiritual curiosity to philosophical reasoning. I don’t claim certainty; instead, I assign degrees of probability. For me, everything is open to rational exploration—and the journey of understanding never truly ends.
