The Right Stuff Ending (1983)

A falling stream of water will break into droplets due to the Plateau-Rayleigh instability. Small disturbances can create a wavy perturbation in the falling jet. Under the right conditions, the pressure caused by surface tension will be larger in the narrower regions and smaller in the wider ones. This imbalance will drive flow toward the wider regions and away from the narrower ones, thereby increasing the waviness in the jet. Eventually, the wavy jet breaks into droplets, which enclose the same volume of water with less surface area than the perturbed jet did. The instability is named for Joseph Plateau and Lord Rayleigh, who studied it in the late 19th century and showed that a falling jet of a non-viscous fluid would break into droplets if the wavelength of its disturbance was larger than the jet’s circumference.

Watching rain drops hit a puddle or lake is remarkably fascinating. Each drop creates a little cavity in the water surface when it impacts. Large, energetic drops will create a crown-shaped splash, like the ones in the upper animation. When the cavity below the surface collapses, the water rebounds into a pillar known as a Worthington jet. Look carefully and you’ll see some of those jets are energetic enough to produce a little satellite droplet that falls back and coalesces. Altogether it’s a beautifully complex process to watch happen over and over again. (Image credit: K. Weiner, source)

Help us do some science! I’ve teamed up with researcher Paige Brown Jarreau to create a survey of FYFD readers. By participating, you’ll be helping me improve FYFD and contributing to novel academic research on the readers of science blogs. It should only take 10-15 minutes to complete. You can find the survey here.
Whether you want to slap a simple filter on your photo or get granular and change attributes like color levels and saturation, we've got a list of the Android apps you'll want to use.
” Why is nobody talking about the fact that the Florida shooting was an anti-Semitic hate crime except for Jews? The school was more than 40% Jewish. The shooter was a part of a white supremacist organization, actively and openly hated Jews more than anyone else, would beat up Jewish kids, etc. The head of the white supremacist organization made a public statement that the organization had nothing to do with the shooting but if he had to guess why Cruz did it, it was because the school was predominantly Jewish. “We’re not a big fan of Jews,“ Republic of Florida Militia leader Jordan Jerub stated in an interview with The Daily Beast. “I think there were a lot of Jews at the school that might have been messing with him.”
It seems like only Jewish news sources are reporting on this and the comments on the articles by non-Jews are sickening. People are saying that “Jews want to be oppressed so badly. He shot up the school because they expelled him, not because he hated Jews.” People are saying we’re “appropriating struggles of people of color” by claiming that he killed Jewish kids because he’s a white supremacist. I’m sorry, why can’t we acknowledge that someone shot up a Jewish school because he was anti-Semitic without it taking away from the struggles of other minorities?
When Jews say we are oppressed, people often respond with “show me real hate crimes against Jews and then we’ll believe you when you say you’re discriminated against,” but then someone who talks about wanting Jews dead shoots up a school that’s mostly Jewish and people still refuse to acknowledge that it’s a real hate crime.
The Jewish community is not a large one. I know people who knew some of those kids, who went to Jewish summer camp with them, whose parents were family friends etc. Fuck anti-Semites and fuck people who shoot children and fuck people who refuse to acknowledge that people are targeted, assaulted, and even killed for being Jewish on a regular basis. According to the FBI, 1.7% of Americans are Jewish, but last year 54.2% of religiously motivated hate crimes were against Jews and 11.5% of overall hate crimes were against Jews.
If your intersectionality doesn’t include Jews, you’re doing social justice wrong.”
