Tonight: "Prophets of Science Fiction" Starts

Set your DVRs for "Prophets of Science Fiction" starting tonight (November 9, 2011) at 10pm EST/PST on The Science Channel.

Tonight the Science Channel debuts a new series about science fiction masters, hosted by Ridley Scott (director of Alien, Blade Runner, Gladiator, etc.). The eight-part series focuses on past masters of sci-fi literature, and how their foreward-looking notions have affected modern science. The first episode is about Mary Shelley (who wrote Frankenstein), and talks about notions of creating life. But the episode also talks extensively about Shelley's personal story (without spoiling it, let's say she had a lot of issues with creating life herself). This is an interesting series for nerds because it's both about history (specifically, the stories behind major sci-fi writers and their work) and about science (cutting-edge stuff that is arguably sorta kinda related to the sci-fi). While some of the science is fairly pedestrian (like mapping the human genome), the history of the writers may not be as well-known, and that keeps things lively. Although I've only seen the Mary Shelley episode, the series looks solid, and I'm looking forward to it. Future episodes will feature: H.G. Wells, Philip K. Dick, Arthur C. Clarke, Isaac Asimov, Jules Verne, Robert Heinlein, and George Lucas.

Here's a good intro video -- it doesn't show much actual footage from the show, but gives a sense of what the series is all about:

Blogger disclosure: I was not specially compensated for writing this review. I'm a big fan of Ridley Scott, so I thought I'd check it out...and hey, I actually learned some stuff about Mary Shelley!

Why a Howling Wind Sounds So Spooky, According to Science

Halloween is swiftly approaching, meaning you'll likely soon hear creepy soundtracks—replete with screams, clanking chains, and howling winds—blaring from haunted houses and home displays. While the sound of human suffering is frightful for obvious reasons, what is it, exactly, about a brisk fall gust that sends shivers up our spines? In horror movie scenes and ghost stories, these spooky gales are always presented as blowing through dead trees. Do bare branches actually make the natural wailing noises louder, or is this detail added simply for atmospheric purposes?

As the SciShow's Hank Green explains in the video below, wind howls because it curves around obstacles like trees or buildings. When fast-moving air goes around, say, a tree, it splits up as it whips past, before coming back together on the other side. Due to factors such as natural randomness, air speed, and the tree's surface, one side's wind is going to be slightly stronger when the two currents rejoin, pushing the other side's gust out of the way. The two continue to interact back-and-forth in what could be likened to an invisible wrestling match, as high-pressure airwaves and whirlpools mix together and vibrate the air. If the wind is fast enough, this phenomenon will produce the eerie noise we've all come to recognize in horror films.

Leafy trees "will absorb some of the vibrations in the air and dull the sound, but without leaves—like if it's the middle of the winter or the entire forest is dead—the howling will travel a lot farther," Green explains. That's why a dead forest on a windy night sounds so much like the undead.

SpaceX's Landing Blooper Reel Shows That Even Rocket Scientists Make Mistakes

On March 30, 2017, SpaceX did something no space program had done before: They relaunched an orbital class rocket from Earth that had successfully achieved lift-off just a year earlier. It wasn't the first time Elon Musk's company broke new ground: In December 2015, it nailed the landing on a reusable rocket—the first time that had been done—and five months later landed a rocket on a droneship in the middle of the ocean, which was also unprecedented. These feats marked significant moments in the history of space travel, but they were just a few of the steps in the long, messy journey to achieve them. In SpaceX's new blooper reel, spotted by Ars Technica, you can see just some of the many failures the company has had along the way.

The video demonstrates that failure is an important part of the scientific process. Of course when the science you're working in deals with launching and landing rockets, failure can be a lot more dramatic than it is in a lab. SpaceX has filmed their rockets blowing up in the air, disintegrating in the ocean, and smashing against landing pads, often because of something small like a radar glitch or lack of propellant.

While explosions—or "rapid unscheduled disassemblies," as the video calls them—are never ideal, some are preferable to others. The Falcon 9 explosion that shook buildings for miles last year, for instance, ended up destroying the $200 million Facebook satellite onboard. But even costly hiccups such as that one are important to future successes. As Musk once said, "If things are not failing, you are not innovating enough."
