Ask a Scientist's 5th BIRTHDAY PARTY: Physics Circus Part II
Hey everybody, Ask a Scientist is FIVE years old! To help us celebrate this momentous milestone, ringmaster Zeke Kossover and his crew of sensational sideshow scientists are returning to the big top to astound, confound, and expound! Tonight Zeke will perform a whole new set of dazzling demonstrations that illustrate physical principles — this time kicking it up a notch with torches, machetes, and broken glass. Why is a wooden stake better than steel for killing a vampire? What happens to an iPod dropped into liquid nitrogen? Will a toy boat float on gas? Can Zeke break a stack of wooden boards with his hand? How much fun is it to ride a hovercraft? Find out tonight!
Ringmaster: Zeke Kossover, physics teacher at Jewish Community High School of the Bay.
The crew: Tucker Hiatt, physics teacher at The Branson School and director of Wonderfest; Leif Steinhour, Constructor, One Off Shoppe.

Topic: Robots
From Talos and Golem to Rosie the Maid and KITT the Car, artifical humans have long been a source of fascination to real humans. While fiction and fantasy abound with an animated cast of automatons ranging from evil to endearing, today's real robots are building our cars, defusing roadside bombs, and vacuuming up the dog hairs while we're at work. Find out what David Calkins, one of America's most respected robotics authorities, has to say about the past, present, and future of artificial intelligence. Among his numerous titles, David is president of the Robotics Society of America, founder of the ROBOGames, and co-founder and president of ComBots — the country's largest organizer of robot combat. So if you've got questions about robots, this is clearly the guy to ask. Oh, and I forgot to mention, David will also be bringing some very special guests with him: ROBOTS!

Topic: Native American Science
Tonight Berkeley astronomer Isabel Hawkins and the Native American Academy's Rose von Thater Braan will join forces to discuss the topic of Native science. Isabel will talk with us about Native American astronomy from a western perpective, and Rose will address how Indigenous learning processes differ from the western scientific method that most of us are probably used to. You may already know that among the ancient world's top astronomers were Native Americans. For example, Mayan measurements of the known planets' synodic periods were every bit as accurate as Ptolemy's, and their calendar was so precise that it could predict the occurrence of eclipses to an error of one day in 6,000 years. But despite the concurrence of Mayan and Greco-Roman observations, the methods and goals of western vs. Native science contrast with one another in some thought-provoking ways. Discover how these two world views differ, what they share, and how bringing them together holds the potential for a paradigmatic shift and the emergence of a whole new kind of science.
Speakers: Isabel Hawkins, Research Astronomer at UC Berkeley. Rose von Thater Braan, cofounder of the Native American Academy.

Topic: Birds, Bees, and Boids
Everyone's seen birds flying, ants foraging, bees working, and fish swimming — all with the apparent purpose and coordination of a single conscious organism. But with no leader, no centralized management, how does each individual participant know what to do and where to go? The collective behavior of such animals — each oblivious to the master plan, but contributing to the group's goals and success — is what's known as swarm intelligence. Researchers have found that such self-organizing systems function through constant interactions between individuals, each of which is following simple rules. In 1986, computer graphics researcher Craig Reynolds created a steering program called boids, in which life-like graphical objects follow three basic rules of motion. The result looks awfully familiar. He is now a leader in the field of computer animated crowd simulation, doing research on visual effects for films and video games. Tonight Craig will talk with us about his work and how it relates to biology, society, business, robots, and more!

Topic: Individual Differences in Perception
It's probably occurred to you that the way you perceive the physical world might not necessarily be the way other people perceive it — that what you see, hear, feel, taste and smell may be experienced differently by someone else. But what does science have to say about the matter? Research on the subject of individual differences in perception bears some interesting observations. For example, gender plays a role in the performance of visual tasks involving spatial discrimination and color, sensitivity to sounds and odor, and responsiveness to pain. Personal experience contributes as well — wine connoisseurs, musicians, and video gamers develop, respectively, heightened ability in detecting odors, sounds, and visual targets. And of course genetic quirks (like color-blindness, synesthesia, or supertasting abilities) also shape each person's unique experience of the material world. Come learn more about this fascinating and most fundamental of topics, and participate in a casual on-site research study!

Topic: Tornado Research in the Field
"Tornadoes are without question the ultimate manifestation of extreme weather. No other meteorological event is as violent or awe inspiring." (Chris Burt, Extreme Weather) You better believe it! While even a humble F0 or F1 on the Fujita Scale (like the one that visited South San Francisco in 2005) can damage property and push cars off the road, a monster F5 tornado can rip a house right off its foundation and obliterate it. These treacherous giants can reach a mile or more in width and can charge across the landscape at over 70mph. And while the sustained rate of hurricane winds has never exceeded 200mph (in recorded history), the winds of the most intense tornadoes can exceed a mind-boggling 300mph. Why and how do these atmospheric powerhouses form? What is it about the unique topography of North America that makes the U.S. home to more tornadoes than any other country? And most important, why would anyone want to get anywhere near one? One way to find out: let's ask John Monteverdi, meteorologist and storm chaser.

Topic: The Science of Baseball
With baseball season just around the corner, whose mind doesn't naturally turn to dreamy springtime thoughts of green grass, peanuts, science, and math? Come hear what our panel of experts has to say about the science of America's favorite pastime. Why is a curveball curved? What makes the sweet spot so sweet? Why do outfielders instinctively run in an arc instead of a straight line? Statistically speaking, are record-breaking players just really lucky? And why have some physicists stated that, at least on paper, hitting a home run is impossible? Come learn the answers to these questions and whatever else you've been wondering about the science and math of baseball. Tonight's event is presented in collaboration with KQED's QUEST Science and Environment Series and Exploratorium. We'll start off the evening by watching QUEST's "Physics of Baseball" video.
Speakers: Linda Shore, Exploratorium Physicist and Director of Exploratorium's Teacher Institute. David Barker, Exploratorium's senior graphic designer and resident baseball fanatic. Mathematician and NPR's "Math Guy," Keith Devlin of Stanford University.

Topic: The 2000-Year-Old Computer (and Other Achievements of Ancient Science)
We learn in school that the science of our ancestors included such endearing bunk as flat planets, geocentric solar systems, and the balancing of the body's four humors. (Even the pre-internet decades of my youth now seem to me like a dark, distant era of ignorance that I can't believe we all survived.) Did our ancient predecessors get anything right? Of course they did. Tonight, science historian Richard Carrier will discuss the nature and limitations of ancient science. While crucial contributions have come from many different cultures throughout history, Richard will talk about a handful of Graeco-Roman scientific and technological advances that might surprise you. Here's a teaser: we'll learn about the Antikythera mechanism, the oldest known computer — discovered in a 2000-year-old shipwreck near Crete. Cool.

Come join ringmaster Zeke Kossover and his crew of sensational sideshow scientists as they (and YOU) perform dazzling demonstrations that illustrate physical principles! Watch, and listen, as sound shatters a wine glass! Ride a hovercraft! Turn on an electric pickle! Try to look at invisible glass! Witness the stopping of time! (Ok, not time exactly, but the hands of a watch.) Zeke and his crew will astound, amaze and explain, every step of the way. Can you think of a more appropriate way to celebrate Mardi Gras, than sledgehammering a bed of nails into the chest of a physics teacher from New Orleans? I sure can't!

Topic: Where Did Language Come From?
Of all the features often proposed for distinguishing humans from the other animals — bipedalism, tool making — it's language that seems to be the most compelling difference between us and them. Even with the disputed definitions of what exactly makes communication among members of a species a "language," there is clearly something unique about the robust, versatile, complex and innovative way we humans transmit ideas and information to one another. The question that neurologist and anthropologist Terry Deacon attempts to answer is one every child has wondered: why can't animals talk? Deacon's research investigates the differences between the brain anatomy and chemistry of humans and that of the other primates, how those differences evolved, and what it all may tell us about the origins of our uniquely human cognitive and language abilities.
Speaker: Terrence Deacon; Professor of Biological Anthropology and Linguistics, UC Berkeley. Author of The Symbolic Species: The Co-Evolution of Language and the Brain.

Topic: The Dark Side of the Universe
A scientific revolution in our understanding of the universe is under way. In the last decade or so, cosmology has become an experimental science that has led to two mysterious observations: about a quarter of the universe is "dark matter," which gravitationally attracts but is otherwise invisible, and about two-thirds is "dark energy," which causes space itself to expand at an ever-increasing rate. That means only a small fraction of the energy in the universe is due to matter that we understand! Pretty spooky. In tonight's presentation, Stanford physics professor Patricia Burchat will guide us in exploring the evidence for dark matter and dark energy, and the experiments being developed to investigate their fundamental nature.

Ask a Scientist's Holiday Puzzle Party
Family dinners are a treasured tradition, and non-denominational mid-winter office functions totally rock, but let's face facts: most holiday parties lack math problems. Not so at Ask a Scientist! Kick off the season of celebration with merriment AND math at our Holiday Puzzle Party — a rollicking math and logic puzzle competition, hosted by teaser-of-brains Wes Carroll.

Topic: Synesthesia
How does violin music smell? What color is Thursday? To most people these questions might seem completely nonsensical, but to people with synesthesia they sound perfectly reasonable. (I've known for as long as I can remember that Thursday is a fuzzy, light olive green. Isn't it?) Synesthesia is a perceptual condition in which there is an involuntary blending of one or more of the senses. The most common form is chromagraphemia, the associating of colors with numbers and letters — but the sense-mingling can get a lot weirder. A synesthete might see moving blobs of color when tasting foods, or taste specific flavors upon hearing certain words. Some savants with computer-like math skills describe their ability in terms of being able to see the shapes and colors of the numbers they're calculating! Once dismissed as a product of an overly active imagination, drug use or even just craziness, synesthesia is finally being recognized as having a biological basis. UC Berkeley's Lynn Robertson will tell us about the current research on this intriguing condition.

Topic: The Science of Big Waves
If you're anything like me, you've watched all the big wave surfing movies just to see the waves. Maybe you've even been down to Mavericks in Half Moon Bay to watch intrepid athletes from around the world ride what many consider to be the most dangerous waves on Earth. If so, you've probably found yourself wondering: just what is it about this legendary surfing spot that makes mountains of water the size of office buildings rise out of the sea? Physical oceanographer Toby Garfield will talk with us about the geography, atmospheric conditions, and basic laws of physics that conspire to create monster waves so big they register on the UC Berkeley seismograph when they crash! Tonight's event is presented in collaboration with KQED's QUEST program — a new weekly multimedia series about Bay Area science and environmental issues. Special guest attendee: Grant Washburn, big wave surfer and filmmaker!

Topic: Exoplanet Update
The last time Chris McCarthy spoke at Ask a Scientist, back in July 2005, I wrote: "In 1995 astronomers detected the first known planet outside of our own solar system — a gas giant (like Jupiter) orbiting a star called 51 Pegasi. Since then, about 150 extrasolar planets have been found around distant stars." Now, two years later, the story is begging for an update. The recent announcement of the discovery of 28 more planets outside of our solar system has brought the total number of known exoplanets to 236! Of particular interest is Gliese 581c, the smallest exoplanet discovered to date. Estimated to be only five times more massive than Earth, Gliese 581c orbits within its dim sun's habitable zone, the region around a star within which a planet's temperature can sustain liquid water on its surface. While we don't yet know if there is water, let alone life, on Gliese 581c, its discovery is a milestone that has astronomers very excited. BONUS: Weather permitting, we'll do a little telescope-assisted skygazing afterwards with Kenneth Frank from the SFAA, the SFSA, and Scope City.

Ask a Scientist's ANNIVERSARY TRIVIA CONTEST!
Can you believe it? Ask a Scientist is celebrating its Linen Anniversary! That's right, it was four years ago that we held our very first event — a lively and illuminating talk about the search for extraterrestrial life, held at San Francisco's beloved Bazaar Cafe. Four years and four dozen topics later, Ask a Scientist is still going strong. Come help us celebrate this perfect-squarish milestone the best way we know how — with a boisterous science trivia contest hosted by science writer Robin Marks. (It's just like a pub trivia night, but without all those other boring categories!) You can bring your own team of ringers with you, assemble a team with others on the spot, compete solo, or just come to cheer, hang out, and learn stuff. The winning team will receive a round of drinks and a really cool feeling of superiority that should last at least several days.

Topic: The Reality of Age Research
Understanding and dealing with disease associated with aging is arguably the greatest challenge for biomedicine in the 21st Century. In fact growing old is the single largest risk factor for human disease in developed countries. Unfortunately, we don't know much about the biological basis of aging — but a series of remarkable discoveries in simple animal models indicates that our understanding of the subject is beginning to change. For example, it is now commonplace to extend the lifespan of lab worms and flies by genetic or chemical interventions. (Do some of you remember Cynthia Kenyon's talk way back in August 2003?) These discoveries have far-reaching implications for how we think about human disease and may serve as the basis for the development of therapeutic interventions. Come learn about the latest in the new field of geroscience and talk about opportunities for living better, more productive lives.

Topic: Sea Urchins
The sea urchin, a spiny little marine critter that looks far more like a plant than a person, has been a jackpot of biomedical insights for over 100 years. In the late 19th century, sea urchins provided researchers with their first glimpse of the fusion of sperm and egg nuclei. Their embryos, which develop rapidly and are easy to observe and manipulate, are providing today's biologists with insights into genetic diseases, cancers, and stem cells. Adding to its value as an interesting research subject, the sea urchin has a surprisingly advanced immune system totally unlike anything seen before. And certain species can live more than 200 years without showing much wear from aging. But biomedical researchers are not the only scientists interested in the sea urchin — its recently sequenced genome yields some tantalizing clues to the mysteries of evolution as well. What is a creature that has no eyes, nose, or centralized brain for dealing with visual or olfactory signals doing with almost 1000 genes for proteins designed to sense light and odors? Darn good question. Let's ask Fred Wilt.

Topic: Terra Incognita
Antarctica, our planet's southernmost continent, is no longer terra incognita ("unknown territory") as far as explorers and cartographers are concerned, but what do the rest of us really know about this mysterious land of extremes? Evidence suggests that the White Continent was once part of a much larger land mass, with a temperate climate, before it began drifting down to its current position back in the Triassic period. Nowadays, 98% of its surface is covered with an ice sheet averaging about 1 mile in thickness, and containing 70% of all the world's fresh water. Antarctica is the coldest, windiest, and driest of the continents — in fact it gets so little precipitation that its interior, despite all the frozen water underfoot, is technically the world's largest desert. If you've never given much thought to this bizarre, distant land — or if you think about it all the time, like I do — this is your chance to learn more. Glaciologist Kurt Cuffey will tell us what his Antarctic research suggests about the continent's icy mantle, and also about the rest of the planet.

Topic: Amnesia
Amnesia, a condition in which memory is disturbed, is no doubt a familiar concept to anyone who's seen a Hollywood movie, a sitcom, or a soap opera. In real life, maybe you've heard the occasional news report about a missing person found wandering around in a fugue state — confused, far from home, with no idea who he is. Or more commonly, of a victim of head injury who retains no memory of the moments, or days, or even years, leading up to the trauma. Horrifying at a most elemental level, the idea of amnesia fills us with angst...and questions. Why is it that some victims forget the past but are able to form new memories, while for others it's exactly the opposite? Is it really possible to repress years of constant childhood trauma and then recall it suddenly, decades later? How can someone be at a total loss for personal and emotional memories, but still be able to read, write, and do math? Come learn how the study of amnesia has provided researchers with important insights into how the normally functioning brain forms memories.

Topic: The Mind-Body Connection
With billions of nerve cells and trillions of connections between them, the human brain is considered the most complex structure in the known universe. But thinking, feeling, and behaving are so fundamental to our existence that healthy individuals rarely stop to ponder the marvelous motherboard behind this effortless functioning. To UC Berkeley professor David Presti, the question of how chemical processes in the brain are related to manifestations of behavior remains one of the most fascinating and challenging issues in neuroscience. How does meditation affect brain chemistry? Why do placebos (sometimes) work? Can our minds influence our health? What do fancy new imaging technologies reveal about the connection between activity in the brain and our thoughts and feelings? Come find out what the current research tells us about these questions and more.

Topic: String Theory Demystified
Modern physics has reduced the complexity of the world to two grand theories: (1) general relativity, the theory of gravity, and (2) quantum mechanics, the theory of the very small. Each theory agrees with experiment beautifully, but only in its own realm. Where the two realms overlap — inside black holes, say, and deep inside the atomic nucleus — these two mighty theories contradict each other. Most physicists agree that string theory offers our best hope of reconciliation. It is a candidate "theory of everything" that shows promise in explaining the "standard model" of all ordinary matter. But can string theory go further? Can it make predictions that are testable? Can it be mathematically elegant? Theorists like Shamit Kachru are working to find out.

Topic: Gene Regulation and You
Before the human genome project was completed, the best estimates were that humans had at least 100,000 genes. But after the genome was sequenced, that number fell to about 30,000. That doesn't exactly sound like enough to account for all of the different cells and proteins that make up our bodies. Furthermore, if humans and chimpanzees share a nearly identical genome, as we've all heard, how is it that we're such different creatures? The answer lies partly in gene regulation — the "switching on and off" of an organism's genes in early development and throughout its life. So it turns out that the source of the differences between us and chimps (and flies and mice and worms et al.) lies not only in the differences between our genomes, but in how our genes are used. Some pretty fascinating stuff has come out of the research on this subject. Mike Eisen will tell us more.

Topic: E=mc2
This legendary equation, part of the theory of relativity set forth by Einstein in April 1905, changed our understanding of nature at the most fundamental level. "c" is the speed of light. It is the ultimate speed in the universe; nothing can go faster. "m" stands for mass. For centuries after Newton it was believed that mass is absolute. But Einstein's equation revealed that mass is yet another form of energy, "E", that can change to other forms — kinetic, gravitational, chemical, thermal, nuclear — and back again to mass. Come learn the meaning of the world's most famous equation, as we explore energy, mass, matter, antimatter, and those pesky missing pieces of the universe: dark matter and dark energy.

Topic: Why We Study Monkeys
Just like humans, the furrier primates exhibit an extraordinarily diverse array of behaviors and social systems, allowing them to exploit a wide range of habitats. By studying monkeys we gain insight into the physiological and behavioral evolution of our own lineage. In other words, when we study them, we're essentially studying ourselves. Anthropologist Alexander Harcourt has been has been travelling the world conducting fieldwork on primate behavior studies since the early 1970’s. He'll tell us how research in the field and laboratory can elucidate the cognitive and behavioral capabilities of monkeys, providing  a window into the evolution of intelligence, and a deeper insight into the biological and behavioral processes that drive our own behavior and thought processes. Tonight's event is presented in partnership with The Leakey Foundation.

Topic: Attention and Memory in the Aging Brain
Normal aging is characterized by deficits that cross multiple cognitive domains, including attention, working memory and episodic memory. UCSF neuroscientist Adam Gazzaley studies the common neural mechanisms whose impairments underlie a broad range of age-related cognitive deficits. Have you ever caught a glimpse of someone and had a flash of recognition, only to find out after further inspection that he or she had some similar features, like clothing or hairstyle, but was otherwise just a random person? Our brains make assumptions to sort through the deluge of sensory information they're constantly receiving. Scientists call this top-down modulation, and its role in the study of the aging brain is one focus of Dr. Gazzaley's research.

Topic: A Cleaner Future for Cars
Our beloved internal combustion engine has gotten us into a whole lot of trouble — namely, pollution, price, and politics. Is there really an efficient, affordable, clean, safe alternative on the horizon? You've probably heard a lot of talk about hydrogen fuel cells — a source of electricity that could power cars whose exhaust would be clean enough to drink (water!). But this technology presents its own challenges, like the amount of energy it takes to isolate pure hydrogen, and the potential to create pollutants in the process. Presented in conjunction with the American Chemical Society, tonight's talk will focus on this and other alternative energy technologies, and will feature selected clips from Nova's fun and friendly new ScienceNOW programming.

Topic: Vision and Misperception
As we go through our daily lives, most of us rarely give a thought to the miraculously complex operations that allow us to understand and negotiate all the stuff we see. The field of vision research has advanced by leaps and bounds in the past two decades, with the advent of functional magnetic resonance imaging. But what do those pretty pictures of highlights on the brain really tell us about how we see? Ariella Popple, a vision scientist from UC Berkeley, will demonstrate the limits of our perception and understanding with stunning visual illusions and entertaining audience participation experiments, to show that sometimes even neuroscientists don't know what they're talking about.

Ask a Scientist and KQED present: Gray Whale Mystery
Once hunted to the brink of extinction, the gray whale has made an amazing comeback in the last 80 years. But in 1999 and 2000, these unique creatures suddenly began to disappear by the thousands — losing an entire one-third of their population. In the Gray Whale Obstacle Course episode of KQED's Jean-Michel Cousteau Ocean Adventures (airing July 19th), Cousteau and his team look for answers as they travel the friendly giants' long migration route through polluted waters fraught with hungry killer whales and dangerous military sonar, all the way to their diminishing Arctic feeding grounds. Come get a sneak preview of this thought-provoking episode and learn more about these fascinating animals at tonight's talk, co-presented with KQED.

Topic: From Galileo to Einstein—Classical Physics 101
Classical physics tells us many things that are both little-known and fascinating, and has implications that are both profound and controversial. Tucker Hiatt, everyone's favorite physics teacher (even if you don't know it yet), will show us how every step we take moves the entire Earth; how Galileo's insights into relativity led smoothly to Einstein's; and how while Newtonian mechanics is deterministic and quantum mechanics is random, neither quite leaves room for free will. Whether you last picked up a physics book decades or days ago, don't miss this chance to brush up on space, matter, energy, entropy, heat, electricity, magnetism, light, radioactivity, and even a little chaos.

Topic: Forensic Science—the Science of the Sleuth
Forensic science has come a long way since fingerprint comparison, "dust" analysis, and toxicology were first introduced at the beginning of the last century. The methods used by these disciplines have since been modernized, and scientists have expanded their mystery-solving toolkit to include such powerful techniques as forensic DNA typing, bloodstain pattern interpretation, and trace evidence analysis. What can DNA analysis of the grime under the fingernails of a corpse tell us? What mysteries can be revealed by an examination of the pattern of blood drops on a wall? Do fingerprints really provide an absolute identification? Come find out!

Topic: Genomes—From Human to Neanderthal
Until very recently, the only DNA recoverable from extinct species was from the mitochondria — the cell's energy producing organelles. While mtDNA reveals much about our evolutionary family tree, it's nuclear DNA that tells the real story of life. Now, with the exciting news that scientists at the DOE Joint Genome Institute have successfully sequenced nuclear DNA from an extinct cave bear species, that story is about to get even more interesting.
