Is the Gulf of Mexico getting warmer? The Gulf of Mexico sea surface temperatures have run above normal over the past year, but they have sharply risen even higher in recent months. Now, they are about three degrees above average, and that is likely to have a bearing on weather across the central and eastern […]

How do you calculate the parallax angle? star parallax relation: parallax angle p in arc seconds = B / d. The baseline B is in units of A.U. and the distance d is in units of parsecs. For measurements from the Earth, B = 1. How do astronomers use parallax? Astronomers estimate the distance of […]

What is the lightest magnetic material? With a density of about 2 mg/cm3, comparable to that of aerogel, carbon nanofoam is one of the lightest known solid substances. But what’s most remarkable about the material, the researchers said, is that unlike other forms of carbon, the nanofoam is ferromagnetic, like a refrigerator magnet. What kind […]

What is the relationship between reflection and refraction? Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or the bending of the path of the waves, is accompanied by a […]

What must occur in order for matter to change states? In order for matter to change phases, there must be an overall loss or gain of heat energy. During the processes of freezing and condensing (i.e., when a liquid becomes a solid or when a gas becomes a liquid), there is a loss of heat […]

What is the purpose of the grasshopper? Grasshoppers are the major, above ground, insect consumer of vegetation on grasslands. They have an important role in the ecosystem as prey for other animals and in nutrient cycling.
