Experience Strandbeest: The Dream Machines of Theo Jansen at the Exploratorium from May 27 to September 5, 2016. Jansen’s strandbeests—“beach animals” in Dutch—are enormous, self-propelling kinetic creations. Constructed largely of PVC tubing and other hardware store materials, strandbeests are mesmerizing in their motions and eerily lifelike. Equipped with sensory organs and ever-evolving survival strategies, they walk a wandering, wind-blown line between art and engineering, mechanics and biology. Physicist-turned-artist Jansen has been creating strandbeests since 1990. Iteratively designed and intricately assembled, Jansen’s self-propelled creatures have evolved over the years, becoming increasingly complex and lifelike, with specialized adaptations to help them survive in their seaside environment. On tour for the first time in North America, the exhibition is illuminated by artist sketches, immersive video, live demonstrations, and the lyrical photography of Lena Herzog, who spent more than seven years documenting the strandbeests’ evolution.

Versatile aluminum, once worth nearly twice its weight in gold, has since become the quintessential metal of our modern lives. While successfully isolated by Hans Christian Ørsted in 1825 and Friedrich Wöhler in 1827, metallic aluminum remained hard to obtain until the end of the nineteenth century, when a new smelting process made it inexpensive to produce. Find out more about aluminum from Exploratorium scientist, Ron Hipschman.

For the solar eclipse of 2016, the Exploratorium was on the island of Woleai, in Micronesia, with multiple telescopes trained on the sun. These telescopes were connected to a laptop holding custom-made software that looks at the movement of the moon and the brightness of the sun. Composer Wayne Grim used this software to create a live composition based on the data. The musical composition uses rotational and orbital periods of the Earth, moon, and sun as formal elements.

In this video, Exploratorium Senior Scientist Paul Doherty explains why you rarely see a true scale model of the Earth, sun, and moon. Understanding the true scale of the solar system helps us appreciate the rarity of total solar eclipses: it’s unusual when objects at such distances line up perfectly.

Únete a la astrónoma del Exploratorium Isabel Hawkins quien junto a la educadora del Exploratorium Liliana Blanco explican los movimientos de los astros durante un eclipse total de sol. A través de demostraciones, ellas muestran cómo la luna, el sol y la Tierra se alinean para crear la coincidencia cósmica que llamamos un eclipse total de sol.

In this video, Exploratorium Senior Scientist Paul Doherty explains why we don't have a total solar eclipse every month. A total solar eclipse happens when the moon crosses between the sun and Earth and casts its shadow onto our planet. But the orbit of the moon is tilted relative to the orbit of the Earth around the sun, so the moon often passes below or above Earth. At those times, it does not cross the line between the sun and the Earth, and therefore does not create a solar eclipse. There are just two times a year in the Earth's orbit when there is a possibility of a total solar eclipse.
