Some thought experiment about the well known Ship of Theseus. It goes like this: imagine a ship leaving shore to go on adventures. Every day, the ship gets damaged and repaired with new material. One day it is a piece of the hull, another day, it is the sail, and so, and so. Eventually, all the elements of the ship have been changed. Is it still the same ship? One might say yes....
Genetic algorithms are really interesting in my opinion. Not the most efficient, but rather beautiful in the way they work. I especially like them because of the similarities that they share with life. Genetic algorithms are special kind of algorithms that work by modelling how natural selection works in the real world. I shouldn't need to explain how evolution works, but for the sake of it, here ...
The first image from the James Webb Space Telescope (JWST) was uncover a few days ago [1]. This is truely an incredible image, showing the galactic cluster SMACS 0723, which is slowly becoming the de-facto target for newly deployed space telescopes as it was imaged by Hubble, Planck and Chandra before JWST. This image in particular took the JWST 12.5 hours of exposure to be able to see these objec...
I was at AKL 22 a couple of weeks ago: the international laser technology congress at Aachen, Germany. I was present for the interesting technology conference and the live presentations at Fraunhofer ILT....
Time flies: we are already in May, and I haven't got time to even post these pictures in time......
I wrote last year about the effect of CME on the thermospheric density and what are the effects on satellites inside the thermosphere, typically at the altitude of the Starlink satellites. You can find this post here....
So this post is a simple shout-out to some other blog I discovered a few months ago. At the time, I was browsing hacker news and saw this post about optics. Great! I love hacker news for this. They mostly have posts about computers and programming but every now and then, there is a post about something totally unrelated, be it optics, physics, environment, etc... but always some quality content. T...
I have always been interested with optics and vision. My path led me to a more technological approach of optics, aka photonics, but I still am fascinated by the process of vision. How the image is formed in the eye, how it is interpreted in the brain and so on. This led me to learn a few things that apparently are not so well known about our own eyes. One of these things is the subject of this pos...
