In Science We Trust?

Put on the headphones if you're at work. It's worksafe, but there's music. The first few seconds of the video explain the point of it all:

They really don't make flags like they used to

Wikipedia says: "The Benin Empire or Edo Empire (1440-1897) was a pre-colonial African state of modern Nigeria. It is not to be confused with the modern-day country called Benin." In Nigeria, Benin City still sits to mark the region, a central part of the slave-trading region of the 17th century.



I want to learn more of the kinds of world history I missed in middle and high school, either because it just wasn't taught (where do kids learn about the Benin Empire in high school history?) or because in all my moving around (five high schools, really and truly) in my youth, I missed out on some curriculum.

This is the sort of thing I've missed.

Nothing's where you think it is



"What do maps have to do with social equality, you ask?"

The good doctor (don't let me say "phlox" here) has a point. Size on a map matters, kids grow up seeing disproportionate sizes, and perhaps, attributing disproportionate values, even unconsciously. I think that as they learn mapping, learning about different projections, and the reasons for them, will continue to be important.

When I lived in Australia, I had a "corrective map of the world."

How much do these things matter? Why?

And I did crack up at the video clip. A lot.

The Spirit Bears

I'd never even heard of the Sloth Bears of Sri Lanka. Wow.



The subsequent parts of this documentary are at http://www.youtube.com/user/neofelisman

There's more to this than Sloth Bears, of course. There are vultures, leopards, deer, buffalo, the aboriginal Vedda people, hornbills,

Scientific literacy for girls - it's like seeding the future

Maybe I just cry easily, but this video from the National Science Foundation pushed me over into tears:



I'm saddened when I listen to teenagers, or even adults, or read what they've written online, and it smacks of scientific illiteracy, or even scientific ambivalence.

A couple of years ago, I took a college-level class in which we studied, among other things, the effect of the full moon on behavior. Study after study we examined showed that even when, for example, emergency room staff or police officers say people behave more wildly during a full moon, statistics -- based on arrests, ER visits, psych ward incidents, and other apparent behavior measures -- show that there really is no causal relationship between behavior and the phase of the moon. (In the few small studies that show some minor correlation, it can be explained elsehow, e.g. the full moon only increased wild behavior when the weather was also warm and folks were hanging out on the street more.) But after this investigation, students still insisted that no matter what science suggested, they knew that the full moon affects behavior because their nieces and nephews threw more tantrums, or they saw more chaos on the job, or whatever. Science was irrelevant. They didn't seem to get how it worked.

The kids in this program are excited about science. The topic at hand is astronomy, but they're not all interested in that, specifically. Some want to be doctors, one says she wants to be a marine biologist. Some might even end up being teachers, or stay-at-home parents, or captain ferries that cross the bay. But they're learning, they're excited about learning, and they're excited about science. This is priceless. These are the kids we need growing up into our future, and making it go.

I'm not sure why I cried when I read this. Maybe it's because these are kids mostly from Oakland, and mostly African-American, and the high school dropout rate in Oakland's phenomenal, especially within the African-American community. Maybe it's because a female, African-American astronomer is part of their worldview now. Maybe it's because these are girls, and the adults working with them seem so much to care that they grow up with positive, science-related educational experiences. Maybe it's because these are kids and need a positive science background, and many public schools can be a hard place to get that these days, and the Girl Scouts and Chabot Space and Science Center and the other people and organizations behind this program are offering it to them.

These are kids who will grow up as better critical thinkers, with experience reading about science and learning how it applies in "real life." Their own experiences and perceptions won't, as much, form the bases for their realities. Their understanding of what is possible out there, both in science in general, in the universe, and in their own lives, are forever expanded.

Now it's your turn to ride across North America

smooth cruising

Cruising on a cable car northeast down Market Street, 1905 (San Francisco, California, USA)



A year later, most of these buildings would be shaken or burned down, or both.

The Ferry Building is still there. What else can you see?

Please note that the interplay of pedestrians, bicycles, automobiles, and public transit was only a little less chaotic then than it is now.

Spring came in like a big red lion

After several years of Australian drought, Broken Hill, on the west side of New South Wales, goes black in a dust storm:



But that's not all. Sydney is hundreds of kilometers to the east, and is getting whacked with it too, as is Queensland farther north. This is pretty much kicking ass in the western third and northern two thirds of the whole huge country.

It brings to mind images I've seen of the storms heralding North America's dust bowl of the Great Depression in the 1930s.



Share photos on twitter with Twitpic dust storm in Sydney






Reuters covers some of the reasons for the dust storm. A friend of mine was reporting rain where I used to live, in Australia, with some of the creeks flowing across roads. (This is normal, it's rural, and the bridges are concreted smooth spots across the creeks.) The front that caused those storms stirred up the dust:
During winter in Australia low pressure storms are generated in the Indian and Southern Oceans, whipping up huge seas and creating severe cold fronts which sweep across southern and eastern Australia.
This caused a thunderstorm with winds of 100+km/hr in South Australia. Those winds lifted the dust from dessicated outback and marginal lands. Just as happened in the thirties in North America (and Australia too, for that matter), the soil was loosened and blew east into Queensland and New South Wales.

And addressing the question of whether climate change caused the dust storm:
....dust storms are usually restricted to the inland of Australia. Occasionally, during widespread drought they can affect coastal areas. Australia is battling one of its worst droughts and weather officials say an El Nino is slowly developing in the Pacific which will mean drier conditions for Australia's eastern states.


We also, for what it's worth, can't say whether climate change caused Hurricane Katrina. (Al Gore was wrong to imply that it did, and it affected his credibility for me, when I saw An Inconvenient Truth.) We can only look at patterns, not isolated events. But we do know that this dust storm was caused by changes in Australia that have come about as a part of a pattern of change in their part of the world. Did climate change cause the dust storm? No way to say. Did climate change cause the conditions that led to it? So far, probably. We shall see.

Dramatic pics in this story
Quite a lot of pictures here
My friend David Morgan-Mar has a dramatic set of photos, and his reaction, here.

Slipping past another marker on the orbital calendar

This is the September equinox. I grew up calling it the Autumnal Equinox, but having traveled in the Southern Hemisphere now, I'm going to have to go with the global flow and call it the September Equinox. Here in central California, summer has been droughty, not as hot as it can be, but with some sizzling days. As much as that autumn is still dry most of the time, and grasses turn from gold to brown, I welcome it. I welcome the shifting of the stars, the return of Orion to prominence. I welcome being able to sleep at night without tossing and turning on top of the blankets in a sweat. I welcome the buckeyes falling from the buckeye tree next door. This year I intend to plant quite a lot of them in cans, to keep the species going through habitat loss.

Points along the path as the earth turns aren't part of a religion for me. I notice the Pagan and Christian, and sometimes other markers for stops along the seasonal paths, but I don't notice them in terms of gods or goddesses or the supernatural.



They keep my eyes and ears open.

They tie me to the earth, and that's important for me. Keeping my awareness on the planet (and the universe) that, probably without even knowing it, keeps conditions so that I can live the life I live now, helps me remember that one of my responsibilities is to care for it. One reason I like geography is that it's about something, some place, I love -- and if we love something, why wouldn't we want to learn more about it and take care of it?

Not only does the Time and Date link have a great explanation of how and why the equinox is what it is, it's full of more awesome links to information and fun.

Today, I'm heading out into the garden to separate the green-bin pruning from the compost-pile pruning, to pull down the remains of the corn, harvest some potatoes, sort out some pole-bean seeds for saving (and feed the rest to the chickens), and start preparing the planting beds for fall's parsnips, spinach, lettuce, carrots, and sugar snap peas.

I figure the bad guys can take care of themselves.

When the polar ice melts and the secret lairs are exposed, Superman will be at risk, too -- that's a terrifying thought.

sense of place - Beach Chalet


Beach Chalet mural
Originally uploaded by marymactavish.
The Beach Chalet, with breathtaking Depression-era art downstairs, and fabulous burgers, beer, and ocean view upstairs, is probably one of the least well known of San Francisco's most wonderful places. It's in the northwest corner of Golden Gate Park, across the Great Highway from the beach. When you visit, I will take you there.

Before my sister died, this was on the list of places she wanted to go again. I'd never been, had no idea it was there despite years of hanging out (and a few months of living in) San Francisco. Now, it has emotional value for its art, as well as having been the last place I had a coherent conversation with my sister. (Brain cancer sucks.)

(Clicking through to the flickr page will give you more info, and lots of links.)

The maker explains at http://blog.blprnt.com/ -
GoodMorning! is a Twitter visualization tool that shows about 11,000 ‘good morning’ tweets over a 24 hour period, rendering a simple sample of Twitter activity around the globe. The tweets are colour-coded: green blocks are early tweets, orange ones are around 9am, and red tweets are later in the morning. Black blocks are ‘out of time’ tweets which said good morning (or a non-english equivalent) at a strange time in the day.


Much more info is at the post, with related images and explanation.

I awoke last night to the sound of thunder...

Just one more gorgeous picture from the "big" bay area storm. Would have linked this earlier had it been up then.

It's still raining, but not lightninging. It feels unsettled, like seasons are changing a bit earlier this year. I hope this portends a proper wet El Niño effect this coming winter.

I wasn't expecting an earth-shattering kaboom

Ian O'Neill posted about his experience watching the shuttle sail overhead, and I added mine in a comment:

In 1996, for some reason, the shuttle flew over Sacramento on its way to Edwards.

It went over at the very crack of dawn, so I went outside a bit before that, wrapped in a blanket, and lay back on the sidewalk to wait.

Soon, in the dark east, a hot pink triangle materialized, and slid quickly overhead. I think it was pink from the heat. It was close enough to see that it was clearly a triangle, and clearly the shuttle, but I could see no details.

It moved silently over me, then disappeared into the equally pink sunrise to the east.

I wandered back into my apartment, curled up in bed, then as I was drifting off, the BOOM that you experienced rattled my window glass. I jumped out of my skin, and then burst into laughter.

It was honest joy.

I am a total shuttle-hugger, and that morning made among my most memorable space-related events.
