A CROW TRIED TO GO IN OUR CLASSROOM AND HE HAD A PEN
yes hello i am here to learn geometries
That crow is more prepared than some of my students.
You’ve all just like, completely skipped over the possibility that this crow has seen people using pens in this room, found one, and is trying to return it. There’s been videos of crows picking up sweet wrappers and stuff and placing them in bins after seeing humans put their litter in bins. I really do believe that this crow is trying to return the pen and that is ADORABLE AS HELL.
THEY ARE SO SMART I LOVE THEM
Crows are thought to be self aware by some scientists. Its perfectly possible the crow wants to return the pen to humans. Knowing it belongs to humans.
Corvids. Who KNOWS. :)
Another cool crow deal: Once, when trying to assess if crows could reason and use tools, scientists had two crows who didn’t know each other each take a wire from a table (one was hooked, one was straight) and try to grab meat from a bottle with it. The crows could see each other, though they had separate bottles. Only the straight wire worked for this, so they hypothesized that if crows could reason, the second trial would have the two crows fighting over the straight wire. The second trial started and, to the surprise of the scientists, the two crows both went for the bent wire, one held it down and the other unbent it. They both got meat out of their bottles. They came to a peaceful solution without verbal communication. Crows are probably smarter than we are.
Is this Canada? This seems like Canada.
canuckistan is a really interesting place
Pulling Polymers Yields Insights into Mechanical Behavior
In collaboration with colleagues from Berlin and Madrid, researchers at the Department of Physics at the Univ. of Basel have pulled up isolated molecular chains from a gold surface, using the tip of an atomic force microscope (AFM). The observed signal provides insight into the detachment force and binding energy of molecules. The results have been published in the renowned scientific journal PNAS.
Atomic force microscopy is a method normally used for imaging matter with very high resolution. The sharp tip of the microscope is used to scan the surface line by line. The resolution is so high, that single atoms can be seen. “This method is roughly equivalent to using the tip of the Matterhorn to scan the surface of a tennis ball,” says Prof. Ernst Meyer of the Department for Physics at the Univ. of Basel. Because of an improved method, the scientists are now able to investigate the mechanical behavior of a single polymer being pulled off a surface.
