The Hertzspring-Russell Diagram is a chart that shows the relationship between luminosity and colour of stars. The chart itself contains information for about 23,000 nearby stars and illustrates the fact that stars only fall within certain allowed regions of the diagram.Image

Just an interesting series of graphs I found showing the varying knowledge of basic scientific facts. While they seem quite good I’m still shocked and at how many people don’t know about the heliocentric model of the solar system. But here’s the real crux of the matter: In 2001 only 53% of Americans replied true to the statement “human beings, as we know them today, developed from earlier species of animals”. When I read that I can somewhat understand why only ~90% of people know about tectonic theory or heliocentrism. Evolution is the key theory in biology, denying this is would be like denying the existence of energy in physics, or atoms in chemistry, or gravitation in astronomy. It simply doesn’t make sense without it.

This graph is showing the relationship between perceived levels of pain (of electric shock) when women are exposed to three sets of images, pictures of long-term relationship partners, pictures of strangers and finally pictures of inanimate objects.
