The film opens with Jean Michel Basquiat's wondering why he is in a hospital and closes with his driving away from New York City. What happens in between seems almost unimportant in this remarkable film that follows the artist through a day in his life. The plot is not the main attraction: Downtown 81 is as much about the painter, Jean Michel Basquiat, as it is about the old New York City.


In pre-Giuliani times, the Lower East Side looked "like a war zone," not a Bohemian playground. Graffiti and sex stores were still rampant. Astor Place didn't have two Starbucks. Most importantly, it seems as though there were as many creative, crazy, and experimental artists then as there are Barnes and Nobles now.


The film seems almost like a home video with something of a budget. The course of events are utterly stream of consciousness. Basquiat runs into some musician friends (rap legend Melle Mel, John Lurie, Lydia Lunch, and Suicide are just a few of the artists on the soundtrack), meets a model/ sugar mama who falls in love with him, sells a painting for $500 (you have to wonder how many thousands it would be worth now), and runs across a suitcase full of money in a dark alley. The plot is merely a whimsical means to the main draw: Basquiat's narration and the visuals,which are stunning after seeing the gentrification of downtown twenty years later.


Throughout the film, Basquiat provides a running commentary in his cool, poetic voice. At times he sounds as if he is trying too hard to be wise, yet his musings evoke Yogi Berra. At other moments, his words resonate with a stirring rhythm like that of slam poetry. In his monologues, he glorifies New York City even while he is being accosted by drug dealers and prostitutes. He revels in the grimy and colorful downtown that seems to be bursting with creativity. On impulse, he graffitis one of his characteristically nonsensical sayings on a wall; the next moment even Basquiat's landlord grabs his french horn and plays.


The atmosphere of the film is almost unrealistic in this sense. As Basquiat stumbles upon friends who always offer him help, or who are struggling with their own artistic endeavors, one has to wonder how uncommon Basquiat's experience had to have been. It seems then that the mission of the film is to educate the viewers, presumably not all artists, as to what it is like to be one. The film focuses on artists, frustrated and successful alike, by showing musicians in the recording studios or performing at a concert and designers creating and showcasing fashion.


Manhattan residents may rejoice in seeing New York as a place where those who are truly talented (or just desperate to become famous) can triumph. As Basquiat says as he is being released from the hospital in the beginning of the film, "I was off to be the wizard." At 19, when Downtown 81 was shot, he probably didn't suspect his rise to fame and ultimately sad end. But, for all the praise he gives Manhattan, he seems perpetually lonely and uneasy. The common ways we identify the 1980s (drugs, bad hair and clothes, promiscuity) are all present in the film, but instead of regarding them as the excesses of the time, they for once seem like the symbols of people who were trying to find a new identity for artists in America and more specifically in New York City.


Downtown 81 will also be shown with Heart of the World, a six-minute black-and-white short.

Researchers Find How ‘Oobleck’ Works

The secret to understanding how oobleck — a Dr. Seuss-derived nickname for the combination of corn starch and water — works has finally been unraveled, a new Cornell study reports.

As a non-Newtonian fluid, oobleck has properties of both liquids and solids. When stirred slowly, Oobleck behaves like a liquid, but when squeezed or punched, it suddenly solidifies. This phenomenon of increased fluid resistance, or viscosity, as more pressure is applied is called shear thickening and it occurs in suspensions, or mixtures of particles suspended in a liquid.

Researchers at Cornell and the University of Edinburgh worked together to figure out the underlying mechanism in shear thickening.

According to first author Neil Lin grad, there are two likely explanations for shear thickening. The first and most popular one proposes that when stress is applied, particles are pushed closer together and the fluid between them drains out causing resistance.

“When the shear created by pressure is severe, this resistance can be so large that it locks the particles into clusters,” Lin said. “And these large clusters of particles, due to the hydrodynamic interactions, can inhibit the global flow, which gives you the shear thickening behavior.”

The second hypothesis suggests contact forces, rather than hydrodynamic forces, are behind shear thickening.

“When you deform or shear the sample, the particles come into close contact with each other,” Lin said. Instead of the resistance from fluid drainage, “the frictional contact force between particles gives you this shear thickening behavior.”

Lin’s research group found that this latter hypothesis was correct in explaining shear thickening.

“The first hypothesis has been a more popular explanation in the field for the last few decades,” Lin said. “And we basically proved that this is not the reason. It’s the other way around.”

To test the two hypotheses, researchers performed an experiment in which they stirred a suspension until it created a constant amount of resistance and then measured the resistance just after reversing the direction of stirring. If the hydrodynamic forces hypothesis was correct, the resistance should remain constant after switching the stirring direction, Lin said. The force due to resistance, according to this hypothesis, is the same in the fluid whether the fluid is being drained or flowing back into the space between particles, so it should stay constant when the direction is reversed. If the contact forces hypothesis was correct, the resistance should drop, they reasoned, as soon as the stirring direction is reversed.

Using an MIT-supplied rheometer, a device specifically meant to measure how fluids respond to changes in applied pressure, the researchers stirred a suspension of spherical micro-particles in salt water and measured the resistance in the fluid immediately after the direction of stirring was reversed. They found that the force suddenly drops, which matches the contact force hypothesis. Since the interactions between these micro-particles are simpler than those between corn starch molecules, using this simplified suspension allowed the researchers to unambiguously nail down the origin of thickening as fitting the contact hypothesis.

By beginning to understand the mechanism of thickening, researchers can start to improve its current applications. For example, one of the most popular examples of non-Newtonian fluids in use is body armor. It exploits its strange properties by solidifying under the impact of the bullet, providing protection to the wearer.

Knowledge about thickening can also help to optimize its other applications, potentially improving concussion-preventing helmets, reducing problems in industrial processes, and aiding in the creation of flexible, yet protective spacesuits for astronauts, according to Lin.

The results of this study were published in Physical Review Letters.

    • If you don’t want to be known as the embarrassing resident crackpot, why don’t you try convincing the physicists and related professors on campus of the validity of your ideas rather than spamming comment sections?

      • Dear anon,
        I would be happy to discuss my work with you and to listen to any and all of your scientific arguments why my work is flawed or why my theories are wrong. I would also be happy to give a public seminar to you and any group you think is able to show why my work is flawed and my theories are wrong. You can find the Mathematica presentation of a seminar I gave at Cornell on October 2, 2015. http://labs.plantbio.cornell.edu/wayne/
        If you ask people who attended the seminar, I think that you will find that they do not accept my work yet they cannot find anything wrong with it.
        If you would like to meet, the coffee is on me.
