![]() ![]() He did have a point, it was unlikely that the party would go on for longer than an hour and I was feeling in the mood for some after-party hanky panky. "Besides, you've been looking so fine tonight, I've been dying to take you home for hours." I pouted, half sulkily – half sexily. "I know babe.but they do live next door, and it won't be going on for much more than an hour here anyway." He pulled me to him and kissed my lips. ![]() For us, it seemed very much on the wind-down. It was barely midnight, the drinks had been flowing and the party was still in full swing, at least for everyone else. Still, it had meant we didn't have to call a taxi which had seemed a good idea at the time – right up until little miss miserable had started complaining about one of her impending migraines. He is taking some antibiotics for an ear infection, but a couple of drinks wouldn't have hurt him. Why Jas had volunteered to drive tonight is beyond me. But I like to enjoy life, and the Christmas party is the one time of year we get to put our glad rags on and let our hair down. I like nothing more than a hot scented bath and a quiet glass of wine with Jas.my hubby. I mean, don't get me wrong – I'm very much the stay at home type. She was never happy unless there was something wrong with her. They were an ok couple.as neighbors go, but Kim was one of those hypochondriac types. Experiments were done in Cambridge and Lyon and results published in Physical Review E on June 26, 2009."Aw honey, she always feels ill.I really don't see why they don't just get a taxi home." I was talking about our neighbors Kim and Geoff. In addition to Morris, the research collaboration includes lead author Anne-Florence Bitbol and Nicolas Taberlet of Ecole Normale Superieure in Lyon and Jim McElwaine of the University of Cambridge. Washboard can also cause tiny bumps on steel railway tracks and even the read head in a hard disk can sometimes hop along the surface of the disk to make a washboard pattern. Motocross bikes and snowmobiles also make ripples. Washboard road is analogous to the little ripples that form on wind- or water-driven sand at the beach, and to the moguls which develop on ski hills. Just about any time a malleable surface is acted upon by a sideways force, you will get ripples. Washboard road is familiar to drivers of back country roads the world over but also appears in some other surprising places in nature and technology. ![]() A washboarding plow is quite similar the main difference is that the sandy surface "remembers" its shape on later passes of the blade, amplifying the effect." A skipping stone needs to go above a specific speed in order to develop enough force to be thrown off the surface of the water. "We analyzed this threshold speed theoretically and found a connection to the physics of stone skipping. Ripples appear when the plow moves above a certain threshold speed." We built lab experiments in which we replaced the wheel with a suspension rolling over a road with a simple inclined plow blade, without any spring or suspension, dragging over a bed of dry sand. "To understand the washboard road effect, we tried to find the simplest instance of it, he explains. "The hopping of the wheel over the ripples turns out to be mathematically similar to skipping a stone over water," says University of Toronto physicist, Stephen Morris, a member of the research team. ![]()
