Bajau: The Undersea Hunters

The Bajau people of Indonesia, Malaysia and the Phillipines live their whole lives in and around the ocean. They can dive for 13 minutes at a time to depths of 200 feet and their bodies are different from the rest of us. In particular, they have larger spleens and eyes adapted to water.

In Malaysia, they are banned from the land, so they have made villages on stilts.

The people has a founding myth of a mission to escort a princess, possibly to a marriage. They fail in their duty to deliver her safely. Through shame or banishment, they never return home but wander the ocean for the generations since.

Visualizing Mortality

The Author is 34 and expecting to live to 90. If you are 17 expecting to live to 73, you have half as many X's and exactly the same number of winters. Your odds of living past 73 are pretty good but the shocking lack of infiniteness is unchanged.

Notably, the number of days you get to spend with your parents is probably already past the halfway mark. OTOH, the number of days you deliberately choose to spend with your parents may be much, much below halfway.

Spring 2018 Bridge: Lilliput

For years, I’ve been telling students that under my rules small bridges might have an advantage. For rules like this, it’s a pretty big advantage.

Usually, they all ignore me. Last time, a few didn’t ignore me. This year, six groups took my little advice to heart, and then some. 

Things got a teeny-bit ridiculous.

Wi-Fi Might Have Made Us Smarter

Instead it has spawned an industry with the largest research budgets in history and the smartest people in the world dedicated to making us addicted.

Almost all Americans own a smartphone or a computer.
Each device contains the library of Alexandria.
The sum total of all world knowledge.
You can learn anything. Why don't you?
Too busy tracking social status.
Too enthralled by imagery your evolution can't resist.

Millennials: The New Victorians

When I grew up, Victorian was a term of ridicule. It meant stuffy people who couldn't tolerate the least bit of earthy reality. Most emphatically in matters of romance, Victorians found the sight of a table leg too sensuous.* Exposing an ankle was the sign of a shameless flirt.

At best, it was said that the Victorians' inability to confront human sexuality was compensated by their ability to confront death. I came to expect that these were exaggerations by people who needed to feel better than their grandparents but the word Victorian stuck as a synonym for irrational prudery.

The twentieth century moved steadily away from that ideal. Matt Ridley says the twenty-first is moving back (minus the care for others, fortitude, courage and economic success.) Illiberality in ideas has taken over for years. Now it seems that illiberality in behavior is next.

*It's not true but it is a myth we commonly shared.

SpaceX Launches to Mars

The Falcon Heavy rocket from SpaceX launched on Tuesday. That means that a private company is now the organization in the world most capable of taking large payloads into space; not NASA, not the Russians, European Space Agency, China, Japan nor India: SpaceX.

If the drama was hard to appreciate, consider this for context:

Dinosaurs: Dead Again

You've heard that an asteroid killed the dinosaurs. 65 M years ago an asteroid hit Mexico's Yucatan peninsula, covered the earth in a layer of dust, including rare iridium, destroyed the plant life, then herbivores, then carnivores.

You may not have heard that it was the volcanoes. Starting 70 M years ago, near Mumbai in India, a collection of volcanoes called the Deccan Traps spewed sulphur and ash, including iridium, acidifying the oceans and blocking out the sun...etc. But could you have sworn that it mightn't be both?
