Mark Twain would be happy to know that the fog has returned to San Francisco. Record-breaking heat in mid-July found many of us who don't have air-conditioned homes wishing for fog. We got our wish.

Tune in for the next live Webcast in this popular series, or come to the Exploratorium to cheer on the competitors in person.

5 - ANCIENT WRITINGS REVEALED!
Recently, we watched ancient text revealed and read for the first time in a thousand years! Archimedes was one of the world's greatest scientific and mathematical minds. His thoughts were inscribed on goatskin parchment, but the letters and diagrams were scraped off and written over by Greek monks in the Middle Ages. Now, using an intense x-ray beam generated at Stanford University's linear accelerator, some of the original Greek text was revealed for the first time in the modern world.
6 - AT THE MUSEUM: TACTILE DOME
The Tactile Dome is a geodesic dome about the size of a large weather balloon that you explore in total darkness. For 75 minutes, you feel, bump, slide, and crawl through and past hundreds of materials that have a huge range of shapes, temperatures, and textures. The idea behind this interactive excursion is to make visitors aware of how complex, sensitive, and underappreciated the sense of touch is.
artist who created the dome, Richard Register, said this
about his creation:
"The Tactile [Dome] draws your body in like the Mother Earth herself, pulling you back through evolutionary time and vague fears of death, opening an inner perspective, a magic theater pouring through the mind from places unknown. If you don't believe me, you've probably never been there, because this place is a powerful experience, a reality/imagination trip that leaves few people unshaken."
who have experienced the Tactile Dome describe it in many
"It's like seeing with your hands."
"Very odd & exciting. Great, excellent. WEIRD."
"Sheer fun--surprise mixed with pleasure of discovery and some brief elements of fear."
"Exciting and mysterious, unusual."
