Day 31 - Just A Little Shakey

3/7/2012

:120307: My cell is firmly established on solid ground. Early Monday morning, two strong earthquakes awakened the Bay Area. At 5:33 am, a magnitude 3.5 quake, followed immediately by a magnitude 4.0 quake shook approximately 5.5 miles below the surface in El Cerrito, CA. Another mild aftershock was felt a half hour later.

Though the quakes served as a rude awakening and were felt as far away as Santa Cruz, they were relatively minor. Police dispatchers in the surrounding cities received no reports of injuries or major damage. Nearby transit systems and bridges were inspected and given the all-clear.

My friend, Mac (below) was less than 2.5 miles from the epicenter that morning, and his important job of keeping my mother's feet warm while she sleeps was interrupted by the jolt.

Earthquakes are a constant threat in the vicinity of the seismically active San Andreas Fault, but individual minor quakes are only as significant as something like a nearby tornado: sure you pay attention to it, but if it doesn't destroy your house or community, you can forget about it pretty quickly. Here it is just a few days later and I bet most people have forgotten it already.

Every once in a while, though, an earthquake is a big deal. Longtime residents of the Bay Area will certainly remember the Loma Prieta earthquake (a.k.a. the Quake of '89 or the World Series Earthquake) as vividly as others remember 9/11 or the assassination of JFK.

The Loma Prieta Quake measured 6.9 on the Richter Magnitude Scale. The Richter Scale is logarithmic in nature, so each whole number is 10 times as powerful as the preceding number. That makes the '89 quake roughly 1000 times as powerful as Monday's quake.

Because of the timing of the event, the earthquake happened during the warm-up of a World Series game, making it the first major quake to have live, national coverage on television. It was also the event that triggered more long-distance phone calls than any other date in history up to that point. Everyone wanted to know if their Bay Area loved ones were OK.

As, of course, did I. My mother (the one whose feet are warmed by Mac) was unable to cross the San Francisco-Oakland Bay Bridge because of the collapsed section, and took a circuitous route around the bay on public transportation to get home from work that night, along with everyone else in the same boat. A commute that normally took about an hour on the bus ended up taking her closer to seven hours.

Before cell phones, there was really no way for me to know if she was going to be able to come home at all that night. As a ten-year-old who had just experienced a major earthquake, it was pretty scary. I stayed at a friend's house that night, as did my brother. We didn't leave a note for Mom, mostly because we didn't want to remain in the high-rise apartment building longer than necessary, but she knew exactly where to find us anyway. She called our respective friends' houses around midnight when she finally got home.

Twenty-two years later, I can still remember exactly what I was eating just a moment before the shaking started. I can remember the underside of the heavy wooden table under which we took cover. I can remember exactly what the shaking felt like. I can remember the color of my friend's socks as we ran down eleven flights of stairs without stopping to put on our shoes. I can remember debating whether to continue walking to my friend's (one story) house in just our socks, or to risk going back inside for shoes (ultimately, we decided to go back inside for shoes and to rescue the cat). I can remember the exact clothing items I had to borrow from my friend to wear to school the next morning. I can remember looking around at the empty desks of my classmates the next day, and hoping that nothing terrible had happened to them.

And I can remember swapping where-where-you-when? stories for years afterward.

Day 30 - Neil DeGrasse Tyson Goes All Sagan On Us

3/6/2012

:120306: My captors are still keeping me confined to a small space, but space is all I need...

Plugging his new book, Space Chronicles, Neil DeGrasse Tyson appeared on The Daily Show with Jon Stewart, and nearly made Jon want to become an astrophysicist himself (watch the clip, you'll want to become one, too!).

Tyson is doing pretty well bringing the wonder back to science and making it friggin' awesome—just like the great Carl Sagan. Known as a popularizer of science, Sagan helped people want to learn about the Universe with the same passion as Sagan himself. In Carl Sagan's words:

Some part of our being knows this is where we came from. We've longed to return, and we can, because the cosmos is also within us. We're made of starstuff. We are a way for the cosmos to know itself. The journey for each of us begins here.

As it turns out, the very thing that Carl loved most about the Universe, is also what Neil loves most, and both of them just make you want to pack a bag and head for the stars (well, them and Doctor Who), because really, you're just going home.
The transcript of the video:
The most astounding fact is the knowledge that the atoms that comprise life on Earth, the atoms that make up the human body are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures.

These stars, the high mass ones among them went unstable in their later years. They collapsed and then exploded scattering their enriched guts across the galaxy—guts made of carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself.

These ingredients become part of a gas cloud that condense, collapse, form the next generation of solar systems, stars with orbiting planets, and those planets now have the ingredients for life itself.

So that when I look up at the night sky and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up—many people feel small because they're small and the Universe is big—but I feel big, because my atoms came from those stars.

There's a level of connectivity. That's really what you want in life, you want to feel connected, you want to feel relevant. You want to feel like a participant in the goings on of activities and events around you. That's precisely what we are, just by being alive.
Thanks, Neil. Carl would be proud.

    "A human being is part of a whole, called by us the 'Universe,' a part limited in time and space. He experiences himself, his thoughts and feelings, as something sepa- rated from the rest—a kind of optical delu- sion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest us. Our task must be to free ourselves from this prison by widen- ing our circles of compassion to embrace all living creatures and the whole of nature in its beauty."
                                                         - Albert Einstein
