Imagining the "Zeroth" Dimension

Imagining the "Zeroth" Dimension

On philosophy and friendship - Seneca, Letter 9 :Stoicism Imagining the Fourth Dimension A direct link to the above video is at Here's where we start getting into some possible confusion because the same word can have many different meanings. When people say that "time" is the fourth dimension, what does that mean? But the more we learn about "space-time" and general relativity, the more we realize that time is not just an arrow. This is why, with this project, I prefer to call the fourth dimension duration. Here's something important to remember: none of these dimensions exist in isolation. So. In "Aren't There Really 11 Dimensions?" Last entry, we talked about how it's really impossible for us to "see" the third dimension, because it takes a certain amount of time for the light from anything in the third dimension to reach our eye - and that's just as true for our hand in front of our face as it is for a star ten light years away. One word physicists use to describe the path an object takes within space-time is a world line.

How Brainless Slime Molds Redefine Intelligence [Video] Gardeners sometimes encounter them in their backyards—spongy yellow masses squatting in the dirt or slowly swallowing wood chips. Hikers often spot them clinging to the sides of rotting logs like spilled bowls of extra cheesy macaroni. In Mexico some people reportedly scrape their tender bodies from trees and rocks and scramble them like eggs. They are slime molds: gelatinous amoebae that have little to do with the kinds of fungal mold that ruin sourdough and pumpernickel. Biologists currently classify slime molds as protists, a taxonomic group reserved for "everything we don't really understand," says Chris Reid of the University of Sydney. Something scientists have come to understand is that slime molds are much smarter than they look. This video was produced through a collaboration between NOVA and Scientific American. To test this idea, Reid and his colleagues placed slime molds in a petri dish behind a U-shaped barrier that blocked a direct route to a piece of food.

Mercury and Relativity - Periodic Table of Videos The mind-bending effects of foreign accent syndrome A little-known condition causes people to adopt a new accent – and lose a part of their identity in the process, finds David Robson. Julie Matthias’s family have a game they sometimes like to play after she comes home, disappointed, from another doctor’s appointment. During dinner, they pick a foreign accent, and challenge each other to speak in the strange voice. The playful jokes help to distract from the distress of a condition that her doctors have struggled to treat. Despite having lived in the UK her whole life, Matthias suddenly found that she no longer speaks with an English accent – sounding French or Chinese instead. Matthias is one of a handful of people in the UK with foreign accent syndrome. The causes are complicated, and sometimes puzzling to scientists. Hear Julie Matthias’s accent in an interview with BBC News Then, a few months after these painful episodes started, something even stranger happened. It’s not clear exactly why the car accident caused that shift.
