You Are Getting Sleeeeeeepy.....

Posted October 02, 2012 8:51 AM

From Discover Magazine | rsslist:

Ikeguchi Laboratories has posted one of the most fantastic "physics in action" videos I've seen in a long time. The concept is simple - 32 metronomes on a table, all set to the same tempo, but started at slightly different times. But here's the fun bit - although they begin "out of phase", after about 2 minutes, they all lock onto the same phase and synchronize! (Well, almost all - there's a rebel on the far right that takes an extra minute to get with the program).

Read the whole article and watch the video

And my wife would just say, "So? That's nice dear."

She totally doesn't get the nerdy fascination so many of us are infected with.

My first response to the story was "Why/How do they do that??"

Guess I'm the rebel on the right...

OK. Watched the video now and quickly spotted it was a flexible/unfixed surface.Interesting was that columns (front/back) synchronised before columns (side to side). Apart from the rogue one. I noticed that the rogue's period lengthened in order to get in step...much as a bellringer would do if that far out of place in round ringing.

Sympathiser. Sorry. Note dearth of ZEDz in the corrected version. Happy now?

So you liked 'gandma', huh? (You didn't catch it either, hahahaha! Pulled a Fast One I did!)

You try fat-fingering these posts on a tiny little crap screen at 3 AM and a TOTALLY uncooperative CR4 editor attempting to run (I'm being very generous here; Admins take note) on an Android browser and falling flat on its bloomin' arse? You're darn lucky it didn't come out 'Gandhi with the Wind' or some such. You know, that huge Bollywood Blockbuster wot came out whenever? Or 'Goyim with the Wind'? That campy Israeli Me2 Bollywoodesque yawner, filmed in some backwater Joppa garage? You guys are dman lukky I stirve so hard fer kwalitie!! You've no idea how good you've got it. Bluddy whingers!

Now, let's get down and dirty and get talkin' 'bout that Blighty Weather. You know, Stuff of Serious Import!

Gandma? Pshaw! Trifles!

When I was a kid, I was ALWAYS the one on the end. My Mom didn't get Science, but she GOT me! I came in once with my hair all singed off my head, my face bright red (burnt, no blisters, YET!) and soot all over my head and shoulders. She said three things:

What did you do (no pause to answer).

Dinner's in 5 minutes.

Go wash up.

Most of my friend's parents would have FREAKED! My Mom got it.

My wife gets it, but she's an artist. Things that look cool (like the metronomes) don't require a reason. The just DO!

But explaining it makes her uneasy. So I just go with the flow. And have more great art around my house than I could EVER afford to buy!

There ARE compensations to "being the one on the end".

Good thing some of us march to the beat of a different kettle of fish, no?

"Ug, why can't you just be a normal child like the others? Why must you you draw pix of animals on the cave wall?"

"'Pix of animals', ma? Hell no! This here is the beginnings of 'written language' and is gonna make it possible for our descendants to land on Mars, ma!"

"That's nice, dear."

Check out the archives of BBC Radio 4's "In Our Time" programme. [If the rights legislations let you] Listen to the 5 part series on the invention of language (first broadcast Jan 2012) - it's facinating. I stumbled across them last week.

Now I'm home, I'm able to find the link. Be aware the page number will change as more episodes are added.

Enjoy.

It is a well-know fact that women in their reproductive years will, if grouped together for long periods of time, synchronize their menstrual cycles; grouped together such as in convents and harems, which just goes to show you that King Solomon's having 300 wives and 700 concubines - a THOUSAND woman, total - all having PMS AT THE SAME TIME is proof enough that Solomon wasn't *even* the Wisest Man Who Ever Lived.

Nah. It happens in the countryside too.

[Never noticed that Mum, sis and I synchronised though. Then again, I spent 8 hours a day with a bunch of girls at school, so maybe a higher degree of sequestration is needed.]

Women's prisons would be another source of data.

One wife, two daughters, one niece. Wife slept in our bed, girls all slept in their (one) room. My wife must REALLY have a strong personality, because All of the girls synched with her, over time, but none seemed to synch with each other prior to synching with her.

Yep, I'm the one on the end. I observe these things. Too bad I didn't learn NOT to talk about my observations BEFORE finding out they didn't WANT ME TO KNOW THE RULES.

I got my ears whipped for "WAAAYYYY TMI" before I learned that lesson.

Now one is a nurse (hospital), one is a Med Tech (everywhere they need her), and my niece has gone back home.

The rest of us talk Biological Science all the time. I just don't ever "connect the dots" to my own girls, or wife.

Thanks for finding and posting this great article. GA.

ps: It would be fun to model coupled oscillators as a SPICE model and fiddle with the parameters to see what happens.
