The human propensity for pattern recognition and storytelling has led every culture to invent constellations. Trace the birth of the star groups known in the West, many of which originated in ancient Mesopotamia. At least one constellation is almost certainly more than 14,000 years old and may be humanity's oldest surviving creative work.

A selection of Frost's poems chosen to suit a perfect New England autumn day. Filmed in the beautiful farm country of Massachusetts.

Groove wants someone to keep him company while he’s out collecting.

In the first of six lectures on the bird families of North America, study four groups of birds that most people will find close to home. Begin with waterfowl, birds that swim in fresh water or near the ocean shore. Continue with wading birds, with their distinct physical profile; shorebirds, a vast group which includes sandpipers; and upland game birds.

So far, you've been practicing five-finger scales, but in Western music, a complete scale is an octave, or eight notes. Expand your abilities to play full eight-note scales, and practice with C major, G major and D major. In addition to working on your existing repertoire, you'll add the jazzy "Minor Romp" and "A Turkish Tune" to the mix.

Relive The Rite of Spring's riotous premiere, and examine the qualities that made it the most influential musical work of the 20th century. Observe how Stravinsky evoked ancient pagan rituals through stunning rhythmic asymmetry, bi-tonal harmony, and other daring compositional techniques. Take account of how the Rite changed the way composers thought about rhythm, melody, and orchestration.

Turn from synthetic polymers to biopolymers - those that occur naturally. Focus on polysaccharides, nucleic acids, and proteins (including a special class of proteins, enzymes). Discover that living systems exercise a level of control over the synthesis of these polymers that no chemist could ever hope to achieve in the lab.

Enter another dimension - a fractional dimension! First, hone your understanding of dimensionality by solving the riddle of Gabriel's horn, which has finite volume but infinite surface area. Then venture into the fractal world of Sierpinski's triangle, which has 1.58 dimensions, and the Menger sponge, which has 2.73 dimensions.

Delve into decision trees, which are graphs that use a branching method to determine all possible outcomes of a decision. Trees for continuous outcomes are called regression trees, while those for categorical outcomes are called classification trees. Learn how and when to use each, producing inferences that are easily understood by non-statisticians.
