De estas elecciones solo queda algo claro: hay que leer Los hermanos Karamazov de Dostoyevski. Es obvio que la gente prefiere tener seguridad y perder la libertad, porque el precio de la libertad es tener que pensar
Los “errores” de Fajardo:
- votar en blanco
- no participar en una consulta
- no aliarse con Petro o Uribe.
Los errores de los otros:
- cercanía a grupos armados
- silencio ante la corrupción
- cambiar de principios según las encuestas
- defensa jurídica de mafiosos
- crear bodegas para matonear a los rivales
- hacer campaña con recursos públicos
- falta de experiencia administrativa
- autoría de la fallida ‘Paz total’
- alianzas con políticos condenados
- llamar a destripar a los contrarios
- cambiar de religión por votos…
A mí me parece claro quién sería el mejor gobernante. #FajardoEnPrimera
That snake is scared of falling. In a 2014 study, biologists rigged a fake tree trunk with pressure sensors and watched five snake species climb it. Every single snake gripped the trunk about three times harder than it had to.
The paper, in Biology Letters, gave a clear answer. A climbing snake will spend extra energy to keep from slipping.
A snake has no arms, no claws, and none of the sticky toepads that let geckos hang upside down on glass. The whole climb runs on muscle. A python or a boa has between 200 and 400 spine bones (humans have 33), and the muscles along its ribs squeeze in slow waves. One section grips the bark hard while the other section stretches up, anchors, and pulls the rest of the body forward. Biologists named this motion “concertina locomotion,” after the accordion. It is hard work and it is slow. The snake in the video is moving at roughly 2% of its own body length each second. If a six-foot man climbed a rope at that pace, he would cover about an inch and a half per second.
Greg Byrnes, the snake biologist who led the 2014 study, told National Geographic why his snakes burned so much extra energy holding on: “For a snake, being safe is way, way more important than being cost-effective.” A 30-foot fall probably will not kill the snake. But it lands the snake back on the forest floor, where ground predators are watching. It also means starting the climb over.
The overgrip is a quiet bargain. Burn some energy now, or risk getting eaten later.
In 2021, scientists at Colorado State and Cincinnati discovered a brand-new climbing mode. Brown tree snakes were tying their bodies into a single big loop and inching up smooth poles, almost like a lasso pulling itself up a flagpole. The team called it “lasso locomotion.” It lets the snake climb cylinders more than twice as wide as the older method allowed. It also explains how brown tree snakes have been climbing power poles in Guam and knocking out the electricity.
What looks scary in the video is mostly a snake doing the math on every grip. Most days, that careful overgrip is the only reason a body that long stays in the canopy.

Qué desgracia infinita animalistas peluchistas con cero conocimientos sobre biodiversidad, biología y conservación.
Propuestas que son un desperdicio de dinero cuando la conservación de la biodiversidad y cuando las comunidades rurales están desafinanciafas
@BogotAnfield Egan no es mejor que Nairo, hay que tener en cuenta que tour gano Egan (cortado y con rivales sin mucho peso en la historia), Nairo compitió y ganó más que Egan contra grandes leyendas del ciclismo.
