Walter Munk's Astonishing Wave-Tracking Experiment

An anonymous reader writes in with a look at a scientist's interesting wave-tracking experiment and the incredible journeys that waves make. His name is Walter Munk, now in his 90s and a professor emeritus at the Scripps Institution of Oceanography in La Jolla, California. About 60 years ago, he was anchored off Guadalupe Island, on Mexico's west coast, watching swells come in, and using an equation that he and others had devised to plot a wave's trajectory backward in time, he plotted the probable origins of those swells. But the answer he got was so startling, so over-the-top improbable, that he thought, "No, there must be something wrong." His equations said that the swells hitting beaches In Mexico began some 9,000 miles away — somewhere in the southern reaches of the Indian Ocean, near Antarctica. "Could it be?" he wrote in an autobiographical sketch. Could a storm half way across the world produce a patch of moving water that traveled from near the South Pole, up past Australia, then past New Zealand, then across the vast expanse of the Pacific, arriving still intact – at a beach off Mexico? He decided to find out for himself. That is why, in 1957, Walter Munk designed a global, real life, wave-watching experiment.

I'm not really sure why this whole thing is offensive.

My Mum had sex. At least once because, you know, I'm here. This much should be clear. And if she wanted to have sex with you too? Well, she's a grown woman, she can do whatever she wants. Hell, I hope that at age 60 I'm still getting some as well, especially from people who are around a third my age.

I mean, really. That's some high grade success there. Having earth-shattering sex with nubile young 20-something's when you're 60. That's hardly an insult.

I love my Mum a lot. I want her to be happy. If that means having all the crazy sex she wants, by all means. She can. I'm not going to judge her.

And another thing... what does that say about you? "Yeah bro, I had intercourse with a 60 year old woman! Fuck yeah!". I mean, by all means, if that's what you're into then whatever mate, go for your life. Some people like that. It's fine. Some people are into having sex with blowup dolls. That's weird but if it's their thing, then I'm cool with it. They tend to brag about it a lot less though.

Honestly, the most offensive thing about that is the waterbed. Those things are a piece of shit.

After 1/4 of the Earth's circumference (6000 miles) the wavefront stops dissipating and starts converging.
