Does Earth Have Its Own Neon Sign?

You might wonder what the Northern Lights and neon signs have in common. Actually, a lot! What makes luminous colors shimmer across the Northern sky? The answer is in the Sun. Charged particles are constantly ejected from the Sun. These particles, collectively called solar winds, travel toward Earth with an average speed of 400 kilometers per ...

Botrytis: The Noble Rot

Gray mold is a common disease of small fruits (e.g. strawberries) and flowers (e.g. petunias) in warm, humid weather. It is caused by the fungus Botrytis cinerea, which produces huge numbers of ... Continue reading

Weathering, Erosion, and Deposition

Weathering, erosion, and deposition are processes continually at work on or near earth's surface. Over time, these processes result in the formation of sedimentary rocks. Weathering occurs when rocks ... Continue reading

Fibonacci Patterns In Nature?

FibonacciOften it takes a second look to see how mathematical numbers and patterns fit into the natural world. Numbers, after all, are manmade. However some very interesting number patterns underlie some natural systems in a surprising way. One such number pattern is called the Fibonacci Series, where each subsequent number is the sum of the two preceding numbers. For example 0, 1, 1, 2, 3, 5, 8, 13, 21... The next in the series is 13 + 21 = 34, and so on.

The trick with mathematical patterns is to see them in the first place, and it wasn't until the 13th century that Leonard Fibonacci, of Pisa, Italy, first described this series in a book on calculations. Since that time, scientists have found the Fibonacci Series in many different places. In the plant kingdom petals on flowers and leaves on stems are often arranged in groups of 3s, 5s and 8s. Pine cones, too, show the same series. In the animal kingdom, the spirals of seashells can be found following the series, as can genealogical patterns of honey bees.
