Abracadabra! Magic exhibit now open

The wait is over! Magic is finally open at HMNS. Come explore an array of artifacts connected with legendary performers of the past and present. Among the many intriguing artifacts featured are torches for fire eating; magic lanterns and automatons; Harry Houdini’s trademark milk can and water escape trunk; Harry Blackstone’s “Zig Zag Girl” prop; Mike Caveney’s linking coat hangers; and items from the acts of Doug Henning, Penn & Teller, and other superstars of magic.

“As fascinating as the artifacts are by themselves, we became convinced that they were only “complete” when they were accompanied by performances—in our case both live and taped,” said Joel Bartsch, the museum’s president. “It is only when these artifacts are animated and brought to life by talented magicians that the dialogue loop between the artifact and the museum visitor is completed. The exhibit showcases the wonders of magic without revealing the secrets that make it fun.”

The exhibition will also feature film and video clips of famous magicians, as well as guest illusionists performing live. (Live performances take place between 11 a.m. and 3 p.m., Wednesday – Sunday)

Check out the video below for a preview of the exhibit – Ilona Carson from Channel 13 interviews our magician Richard Hatch, as well as magician/dancers Michael and Jessica from the Rhythm of Magic.

Magic! Houdini’s Needles and Thread

How much do you know about magic? It’s time to see through the illusion! The Magic! exhibit opens tomorrow, Feb. 26, 2010 at HMNS. Throughout the run of the exhibit, check back here for exclusive videos and descriptions of the unique items on display from curator Scott Cervine.

Although Houdini performed large scale illusions, such as making an adult elephant vanish in the Hippodrome Theater in New York, his masterful showmanship also allowed him to make a signature performance from a handful of needles and several yards of thread.

Houdini Needles and Thread
On display in Magic! starting Feb. 26

Houdini would swallow the needles, then the thread. His mouth would be inspected by a doctor to be shown free of guile, and then he would apparently regurgitate the thread, which suddenly appeared between his lips. In pulling the thread from his mouth, the needles were now seen to be threaded at intervals on the thread.

Although not original with Houdini, prior performers had done the feat with a few dozen needles and a few feet of thread. Houdini used enough needles and thread to fill the stage and created as great an impression with these simple, inexpensive items as did with larger props from his workshop in which he invested thousands of dollars.

Charcoal, Bio Char and Nanotechnology

Where's the beef?!

Most of you, my dear readers, have heard of charring or charcoal at some point (a few might even know the term “Charyou Tree” from the novels of Stephen King). So you may be asking yourselves what is biochar? Is it different from normal charcoal? Why are people putting it in the ground and not using it for bar-b-q?

Biochar is organic material, mostly wood, that has been heated until it has been completely carbonized. How is this different from charcoal? It differs in its primary use. When people think of and use charcoal in America, it’s mainly for burning the charcoal. Biochar’s main uses are as a carbon sequester and a fertilizer. What that means is that when wood is turned into charcoal (or biochar) the carbon it holds is not released into the atmosphere. Instead you end up with a little lump of carbon (not like this, but like this). It turns out that lump of carbon can be used as a very effective fertilizer.

Now why do I bring all this up? It’s not only to talk a little about carbon sequestration or to talk about a hobby of mine, but to talk about up and coming science.

Over at Rice University they are using modern methods of chemistry to try and create the best biochar for fertilizer and how to promote it in developing countries.

Why is this important? First it is a way to improve soil quality without adding too many artificial fertilizers and pesticides. Second, it is a way to store the carbon without releasing it immediately into the atmosphere.

Using charcoal as fertilizer is not a new invention. The idea and practice has been around for thousands of years. One example of it has been slash and burn agriculture.

So what does biochar have to with carbon nanofibers?  Both are made from carbon. Both are being worked on at Rice.

So what is a carbon fiber nanotube? It is a string of carbon molecules that have been put together that are about 1 nanometer in diameter.

These smallest of the small have big potential. A long carbon string made using these carbon nanofibers (and buckyballs) have the potential to help revolutionize fields such as electronics and building materials.

Carbon nanofibers have the strongest tensile strength (how well the material stands up to stress) and can also hold an electrical current 1,000 times greater than the copper wires we use.

So, why aren’t we already using it? That’s the really amazing thing. The technology is so cutting (and bleeding) edge that the implementation is not there yet. 

And there are greater things yet to come. “Oh brave new world that has such people in it.”

Happy New (Chinese) Year!

On Sunday, Feb. 14, while we were observing Valentine’s Day, a much bigger celebration got underway in the Far East.  That was the  Chinese New Year, the day when the Year of the Ox ended and the Year of the Tiger began.  And the celebration is still ongoing, as it lasts until the Lantern Festival on the 15th day of the month (this year, Feb. 28).

Like most Americans, I learned the sky as imagined by westerners around the Mediterranean basin, with images from Babylon, ancient Egypt, ancient Greece and Rome, and star names preserved during the Middle Ages by Arabs. So I find it fascinating to think of an entirely different culture and how they imagined the night sky. The Chinese New Year celebration is a perfectly appropriate time to do this, especially since objects in the sky, in particular the moon and Jupiter, serve as the basis of the ancient Chinese calendar.

The date of Chinese New Year varies; it can occur as early as Jan. 21 or as late as Feb. 19. However, anyone familiar with the lunar cycle can easily predict the date for a given year. That’s because China’s New Year always begins with the second new moon after the winter solstice.

Our Gregorian calendar is a solar calendar, based on the apparent position of the sun (and thus, on the Earth’s orbit around the sun).  However, the apparent position of the sun compared to the stars is difficult to observe.  Much more readily observable are the phases of the moon.  Thus the Chinese, like many ancient cultures, adopted a lunar calendar, measuring months from new moon to new moon.  Unlike the Islamic or ancient Roman calendars, the Chinese calendar begins months with the dark of the moon–the day the moon is invisible, not the first slender crescent seen at dusk.

It would be convenient if one year equaled an even number of phase cycles. In fact, however, the moon takes about 29.5 days to go through one phase cycle, so 12 such cycles is 354 days.  This is significantly less than the solar year of 365.25 days, so a purely lunar calendar quickly becomes disconnected from the seasons and useless as a guide for when to plant or harvest.   To keep their lunar months connected with the seasons, the Chinese added a rule: the second-to-last lunar month must contain the winter solstice.  If the old crescent moon of the eleventh lunar month is waning towards new and the winter solstice has not yet happened, that month is repeated.  Similar rules exist for the second lunar month (which must contain the spring equinox), the fifth lunar month (which must contain the summer solstice), and the eighth lunar month (which must contain the fall equinox).  Accordingly, the first new moon after the winter solstice always begins the last month in the Chinese year, and the second new moon after the solstice begins the next year.

Chinese astronomers noticed that every twelve years, Jupiter reappears next to the same stars.   (This is because Jupiter takes 11.86 years to orbit the Sun.)  There were twelve months in a typical Chinese year (although occasionally one was doubled, as explained above).  Also, the Chinese divided the day into twelve double-hours.  They used a system of twelve ‘Earthly Branches’ to designate the months of the year and the double-hours in a day.  Jupiter’s motion in the sky established a cycle of years analogous to the cycles of months and double-hours.  Thus Jupiter became the ‘Year Star’ (Suixing) and years, too, were designated with the Earthly Branches.

Later, as a mnemonic device, the Chinese began to associate the Earthly branches with animals.  (Sources disagree as to exactly when.)  Legends tell that Buddha (or the Jade Emperor) summoned all of the animals to him; each of the first twelve to appear became associated with an Earthly Branch.  The twelve animals are:

1) Rat  2) Ox  3) Tiger  4) Rabbit  5)Dragon  6)Snake  7)Horse  8)Sheep  9)Monkey  10)Rooster  11)Dog  12)Pig

The signs of the Chinese zodiac, then, unlike those of the western zodiac, are not constellations in the sky.  The most well known of the Chinese constellations are the 28 ‘lunar mansions.’  These are small groups of stars very roughly arrayed along the ecliptic, which is the apparent path of the sun, moon and planets across the sky.  As you’ll see in the links below, the Chinese used some stars, such as those in Orion, that are too far from the ecliptic for the moon to pass through them.  The 28 mansions were subdivided into four groups of seven; each group of seven represented one of four Chinese animals associated with the directions and the seasons:

1) The Blue/Green Dragon (Qing Long) of the East, associated with spring.  Note that the ancient Chinese color word qing was quite broad in meaning.  Blue and green were considered different shades of this broadly defined color.

2) The Red Bird (Zhu Que) of the South, associated with summer.   This mythical bird, with red and orange plumage, is distinct from the feng huang, also called the Chinese phoenix.

3) The White Tiger (Bai Hu) of the West, associated with autumn.

4) The Black Tortoise (literally Dark Warrior, Xuan Wu) of the North, associated with winter.  Xuan Wu was always shown as a tortoise with a snake wrapped around it, reflecting the folkloric belief that all tortoises were female and needed to copulate with snakes to reproduce.

Of the stars in tonight’s evening sky, those in Orion and Taurus form part of the White Tiger, while Gemini and the dimmer stars south and east of it belong to the Red Bird.

Along with the four large animals, Chinese astronomers defined three large constellations known as the three enclosures.  The largest of these is the ‘Purple Forbidden Enclosure‘ (Zi Wei Yuan) which includes all those stars near the North Pole of the sky which never set as seen from mid-northern latitudes.  The enclosure is ‘forbidden’ because it includes the North Star, which was the Emperor of Heaven because it always remains in one spot while other stars seem to go in circles around it, as if paying court.

The ‘Supreme Palace Enclosure‘ (Tai Wei Yuan) actually rises in the late evening in February.  Look east about 9 tonight for a set of stars in the shape of a backwards question mark.  We see this as the head of Leo, the Lion.  Rising under the backwards question mark is a right triangle of similar brightness.  For us, this is Leo’s hindquarters, but in China, it’s the northwest corner of the Supreme Palace enclosure.  The other side of this enclosure is a semi-circle of stars westerners recognize as part of Virgo, the Virgin.

The final enclosure, the ‘Heavenly Market Enclosure‘ (Tian Shi Yuan), won’t rise until very early in the morning in February, and isn’t in the evening sky until late May.  It centers on our constellations Ophiuchus and Serpens (Caput and Cauda), just north of the bright summer constellations Scorpius and Sagittarius.

So, I wish everyone a happy Year of the Tiger.  I’ll celebrate it by looking at the stars in a way I ‘m not accustomed to seeing them.
