A Pulse in the LiDAR
A sudden flicker in the spinning beam, Two wheels approaching, a rhythmic stream. A shadow moves, a rapid, spinning trace, Captured in light, held in digital space. The path is cleared, the trajectory is known, Safety preserved in a silicon zone.

Christiaan Huygens
Christiaan Huygens was a Dutch polymath who fundamentally changed our understanding of light through his wave theory. He invented the pendulum clock, which revolutionized timekeeping accuracy, and discovered the composition of Saturn's rings. His work laid the essential groundwork for much of modern classical mechanics.

The Cleanliness of Square-Free Integers
A square-free integer is a number that isn't divisible by any perfect square other than 1. This means its prime factorization contains no repeated factors, making it 'clean' of any redundant prime components. Interestingly, as you look at larger and larger ranges of numbers, the probability that a random integer is square-free approaches 6/π².
