It turns out that Val Kilmer is a man of extraordinary faith. But by the time he finally agreed to speak with me earlier this year, I found a completely different story there. So I thought I was telling a story about where Val Kilmer was. All of a sudden, I realized it had been a really long time since I’d seen Val Kilmer on a big screen. taffy brodesser-aknerĪnd then one day he stopped showing up in movies. Well, I wish I could say that my interest in you was. He was Batman! archived recording (batman forever) 1 He starred as Jim Morrison in “The Doors.” Let’s just say I was testing the bounds of reality. I don’t like you because you’re dangerous. “Top Gun.” archived recording (top gun) 1 What’s your problem, Kazansky? taffy brodesser-akner He was in - archived recording (top gun) 1 He was the quintessential blockbuster matinee movie idol of my youth. I have been trying to write a story about Val Kilmer for about five years. Hi, It’s Taffy Brodesser-Akner, and I’m a staff writer at The New York Times Magazine. Produced by Kelly Prime edited by Mike Benoist written by Taffy Brodesser-Akner and narrated by Julia Whelan Taffy Brodesser-Akner tells a story about how sometimes, in the end, everything is different but everything is good. These results could be relevant for the future design of artificial microswimmers in confined geometries.Transcript Listen to This Article. Similar dynamics is observed for swimming into a curved tube. In contrast, pusher swimmers and those employing normal deformation are unstable and end up crashing into the walls of the tube. Swimmers of the puller type always display stable locomotion at a location which depends on the strength of their force dipoles: swimmers with weak dipoles (small $\alpha $) swim in the centre of the tube while those with strong dipoles (large $\alpha $) swim near the walls. Swimmers with no force dipoles in the far field generally follow helical trajectories, solely induced by hydrodynamic interactions with the tube walls, and in qualitative agreement with recent experimental observations for Paramecium. In all cases, the rate of work necessary for swimming is increased by confinement. In the case of swimming parallel to the tube axis, the locomotion speed is always reduced (respectively, increased) for swimmers with tangential (respectively, normal) deformation. Hydrodynamic interactions with the tube walls significantly affect the average swimming speed and power consumption of the model microorganism. The swimmer propels itself by tangential or normal surface motion in a tube whose radius is of the order of the swimmer size. We use the boundary element method to study the low-Reynolds-number locomotion of a spherical model microorganism in a circular tube.
