Activity: Week of Reflection
n this year 2023, I have been living the easter week, in plenty of meditation from the Peñol, I have enjoyed good readings, the enjoyment of nature, my favorite red wine, and the inevitable rock classics that have always fascinated me.
n incident that allowed me to transcend: Make the permanent
monitoring of the emergency that threatens the communities surrounding the Nevado del Ruiz (Huila and Tolima regions in Colombia) in the event of possible eruption. My sensitive contribution has been the prayer to God so that the Nevado calms down from throwing gases or ashes exceeding 1,700 meters, according to the Colombian Geological Service.
istory reminds us today the tragedy of Armero that 13 of November of 1985, a tragedy that presented the horrifying number of more than 23.000 deaths because of the avalanche, lots of tears that increased throughout the world with the touching episode starring by Omaira Sanchez, the child of 13 years old, a symbol of courage and love for the humanity, the heroine who before dying, was trapped 3 days by her legs, and with water up to her neck, the painful and touching reality that kept step by step the entire world, when there were still no realitys. All the hearts were broken when the girl was saying that she only was worried because she didn’t do her homework, and because the journalists weren’t going to rest.
ut also, during this week that just passed, our curse of drones was present in the midst of the Nevado emergency, and I am saying this because of a transmission of technical experts of the Radio difusora Nacional. They talked about the use of the Parrot Anafi Thermal, the drone 4k- thermographic, they said that is the lightest for the monitoring in the ground, which in the case of height and environment of the Nevado area makes it very easy for the transportation, and I heard that it can fly in the rain. All that report on the radio motivated me to research more, I was able to find out that this drone only weighs 315 grams, and it owns three types of colors, in the thermal spectrum, the absolute thermal mode, the relative thermal mode and the punctual thermal mode, which is used to isolate cold or hot spots and that can very well take advantage of the CCD sensor, because it offers a slightly higher light sensitivity (it captures light better ), produce less noise than CMOS sensors, although they are more complex to incorporate into a camera and can consume up to 100 times more energy than a CMOS sensor, it is also noted that they are larger equipment.
you can see, this report is about my experience during the easter week, which develops from the reflexion mostly in the actual world, the threat of the people life, and the role of the science and the technology to solve problems, sadly, was the issue that was absent in 1985, where before the fragile technology and science, only the spiritual and the conjectures were present.
