The Importance of a Good Sketchbook

A sketchbook is a book or pad with blank pages for sketching and is frequently used by artists for drawing or painting as a part of their creative process. Artists often use large sketchbooks which include wide spaces of blank paper appropriate for drawing. Lawyers use rather large sketchbooks or notebooks known as legal pads that contain lined paper (often yellow) and are appropriate for use on tables and desks.

Principal types of binding are padding, perfect, spiral, comb, sewn, clasp, disc, and pressure, some of which can be combined. Binding methods can affect whether a notebook can lie flat when open and whether the pages are likely to remain attached. The cover material is usually distinct from the writing surface material, more durable, more decorative, and more firmly attached.

Exploring Pinnacles National Park

Pinnacles National Monument was established in 1908 by U.S. President Theodore Roosevelt.

Pinnacles National Park is a U.S. National Park protecting a mountainous area located east of the Salinas Valley in Central California, about 5 miles east of Soledad and 80 miles southeast of San Jose. The park’s namesakes are the eroded leftovers of the western half of an extinct volcano that has moved 150 miles from its original location on the San Andreas Fault, embedded in a portion of the California Pacific Coast Ranges. Pinnacles is managed by the National Park Service and the majority of the park is protected as wilderness.

The national park is divided by the rock formations into East and West Divisions, connected by foot trails; there is no through road that connects the east and west entrances to the park. The east side has shade and water.

Searching for the Milky Way Galaxy

The Milky Way is a barred spiral galaxy some 100,000–120,000 light-years in diameter, which contains 100–400 billion stars.

The Milky Way is the galaxy that contains our Solar System. Its name “milky” is derived from its appearance as a dim glowing band arching across the night sky in which the naked eye cannot distinguish individual stars.

Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Up until the 1920s, most astronomers thought that all of the stars in the universe were contained inside of the Milky Way. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble definitively showed that the Milky Way is just one of many billions of galaxies.

A Spiral Galaxy

The Milky Way is a barred spiral galaxy some 100,000–120,000 light-years in diameter, which contains 100–400 billion stars. It may contain at least as many planets as well. The Solar System is located within the disk, about 27,000 light-years away from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm. The stars in the inner ≈10,000 light-years form a bulge and one or more bars that radiate from the bulge. The very center is marked by an intense radio source named, Sagittarius A*, which is likely to be a supermassive black hole.
