Frenet–Serret Formula ✍️
It explains how a curve reveals its hidden geometry by tracking the way it bends and twists through space. Imagine tracing the path of a roller coaster, a winding river, or the spiral of a DNA strand. At every point along the path, the curve is constantly changing direction, and the Frenet–Serret formulas provide a precise way to describe that change.
They do this by attaching a moving frame of three special directions to each point on the curve. The first points forward along the path, showing where the curve is heading. The second points inward, toward the direction of bending. The third stands perpendicular to both, capturing how the curve twists out of its plane. Together, they form a local coordinate system that travels with the curve itself.
As you move along the curve, these three directions rotate and evolve. The formulas measure this evolution using two key quantities: curvature and torsion. Curvature tells how sharply the path bends, while torsion tells how strongly it twists into three dimensions. If curvature vanishes, the path becomes straight; if torsion vanishes, the curve lies flat in a plane.
Mathematicians and physicists use the Frenet–Serret formulas to study motion, design smooth paths in engineering, understand particle trajectories, and analyze natural shapes. They transform a simple line into a rich geometric story, revealing exactly how space is being navigated at every step.

Our Functional Annotation course has come to an end, and we are happy with how it went. More than 20 early-career researchers explored plant genomics together and brought amazing curiosity to every session. Grateful to all participants—your passion and hard work give us real optimism for the next generation of plant science. 🌱🧬

So Astrofest is done and dusted for another year. For the first time since the early 2000s (when we did model rocket displays) we were volunteers. This time we were running one of the telescope pods - the Smart Telescope pod, which, unlike the other pods, was not limited to a single target. We were all over the sky, making the most of the ease of control and versatility of these fun devices.
@leece and I had three DwarfIIs, there was a pair of Seestar S50s, a Unistellar EVScopeII, and even a Vaonis Vespera II (which is a work of art, as well as being a stunning telescope).
We even had someone doing it oldschool with a guide mount and a DSLR with a very beefy lens!
We started the afternoon with sun and moon viewing - made challenging with the sunlight on our screens. After, one of the S50s continued with the moon for the rest of the night, while the rest of us went on to other targets, including 47 Tucanae, the Cat's Paw Nebula, C65 (The Sculptor Galaxy), The Lagoon Nebula, the SMC, the LMC, and even a random star that someone had the coordinates for tattooed on their arm!
We were on our feet pretty much from 2:30 when we set up to 10:30 when we finally departed, and talked to the public almost non-stop from about 4pm. We answered questions about what these weird looking devices were, and why people were not looking through them, what they could do, how much they cost, and which were the best. This last one was a tough one, as we own one brand, and there was another brand in the same price bracket right next to us :) We were fair, though, and highlighted the pluses and minuses of each. And explaining, many times, that we were not selling them.
Early in the evening Leece did duck off to watch the Astrophotography competition awards, as she had been shortlisted. And, to her surprise, she had just sat down when they announced the winner for the Night Sky Friendly Lighting category - with her image of the rising galactic core over a resort near Bindoon taking the prize!
It was a fantastic, if exhausting experience, and one we look forward to repeating in Feb 2026.

Is there anyone out there who would be interested in developing Course-based Undergraduate Research Experiences (CUREs) based on the genomics of non-model arthropods?
