The Late Movies: The Secret Life of Machines

I love The Secret Life of Machines, a late-1980s series about how everyday machines work. Presented primarily by engineer/cartoonist/artist Tim Hunkin, it's understated, funny, and deeply smart -- a gently curious investigation of how things go. Hunkin wrote about the first series:

The two sides of my life - researching stuff in books for the cartoon strip and making things, had made me realise just how much clever human activity in the world can not be explained in words or suit the format of a book, let alone fit with the publishing fashion of the day. The examples of this which seemed most immediate to me were the everyday machines around the home that everyone takes for granted. I’ve always enjoyed taking machines to bits and trying to mend them. It was always frustrating doing my cartoon strip about this sort of machine – it would be so much better if people could actually watch the machine working.

Hunkin has made loads of machines, as well as the flying pigs and sheep for Pink Floyd's Animals tour. He currently makes coin-operated machines for the Under the Pier Show in Suffolk -- which makes me really, really want to go to Suffolk. But for tonight, enjoy a few of my favorite episodes of The Secret Life of Machines. If you like these, they're all available for free online. (They're also on YouTube and various other spots, with Hunkin's permission.)

The Fax Machine

The first fax machine was patented way back in 1843 by Alexander Bain. In this 24-minute episode, Hunkin and copresenter Rex Garrod explain how the fax machine works.

The Vacuum Cleaner

The very first episode, this explains how vacuum cleaners work, with extensive animation by Hunkin. Hunkin writes:

The vacuum cleaner film was made before Dyson’s cleaners were introduced. These use an old industrial idea of sucking the air and dirt through spiral vanes. This spins the dirt and flings it to the outside of the chamber. Dyson’s version has several stages of vanes and needs no dust bag. Unfortunately the finest particles still get through so filter pads are needed over the outlet. These reduce the suction power of the machines, so I’m not sure they are any real improvement, despite the hype. There is also more awareness of the link between asthma and house dust, so all manufacturers have put more effort into the outlet filters.

The Refrigerator

The most dramatic part is around 2:45 when Hunkin blasts himself in the face with carbon dioxide.

Refrigerators are basically unchanged, but the disposal of scrap fridges is completely different. When I made the film, alternative refrigerant gases were starting to be introduced that are supposed to do less damage to the ozone layer of the atmosphere. Since then though, it has been decided that the gas trapped in the bubbles of the polyurethane foam insulation is also a problem, so now fridges have to be sent for specialist recycling, and every household waste tip has a mini fridge mountain.

Lots and Lots More

Nine of the full programs are available on this YouTube channel, the rest are easily found (in segments) by searching. You may also wish to consult Hunkin's pages on Series 1, Series 2, and Series 3 (The Secret Life of the Office). Hunkin's pages also have links to (legal) downloads of all the episodes.

This AI Tool Will Help You Write a Winning Resume

For job seekers, crafting that perfect resume can be an exercise in frustration. Should you try to be a little conversational? Is your list of past jobs too long? Are there keywords that employers embrace—or resist? Like most human-based tasks, it could probably benefit from a little AI consultation.

Fast Company reports that a new start-up called Leap is prepared to offer exactly that. The project—started by two former Google engineers—promises to provide both potential minions and their bosses better ways to communicate and match job needs to skills. Upload a resume and Leap will begin to make suggestions (via highlighted boxes) on where to snip text, where to emphasize specific skills, and roughly 100 other ways to create a resume that stands out from the pile.

If Leap stopped there, it would be a valuable addition to a professional's toolbox. But the company is taking it a step further, offering to distribute the resume to employers who are looking for the skills and traits specific to that individual. They'll even elaborate on why that person is a good fit for the position being solicited. If the company hires their endorsee, they'll take a recruiter's cut of their first year's wages. (It's free to job seekers.)

Although the service is new, Leap says it's had a 70 percent success rate landing its users an interview. The rest is up to you.

Watch NASA Test Its New Supersonic Parachute at 1300 Miles Per Hour

NASA’s latest Mars rover is headed for the Red Planet in 2020, and the space agency is working hard to make sure its $2.1 billion project will land safely. When the Mars 2020 rover enters the Martian atmosphere, it’ll be assisted by a brand-new, advanced parachute system that’s a joy to watch in action, as a new video of its first test flight shows.

Spotted by Gizmodo, the video was taken in early October at NASA’s Wallops Flight Facility in Virginia. Narrated by the technical lead from the test flight, the Jet Propulsion Laboratory’s Ian Clark, the two-and-a-half-minute video shows the 30-mile-high launch of a rocket carrying the new, supersonic parachute.

The 100-pound, Kevlar-based parachute unfurls at almost 100 miles an hour, and when it is entirely deployed, it’s moving at almost 1300 miles an hour—1.8 times the speed of sound. To be able to slow the spacecraft down as it enters the Martian atmosphere, the parachute generates almost 35,000 pounds of drag force.

For those of us watching at home, the video is just eye candy. But NASA researchers use it to monitor how the fabric moves, how the parachute unfurls and inflates, and how uniform the motion is, checking to see that everything is in order. The test flight ends with the payload crashing into the ocean, but it won’t be the last time the parachute takes flight in the coming months. More test flights are scheduled to ensure that everything is ready for liftoff in 2020.
