Video: Mister Rogers' Neighbourhood is something I recall as a feeling rather than a specific set of memories. Wikipedia claims there was a whole cast of characters — Mr McFeely, Pilot Ito, Officer Clemmons and a few dozen puppets — but I don't remember them. With the passage of time, the show's details have collapsed into a singular sense of comfort and safety, the sensation of laying on the carpet in front of grandma's wood-panelled TV with the big, clicky knobs. Or, at least, that's what I think it looked like.

Video: Some animals are born with natural camouflage that allows them to hide in their native habitats. But what happens when the ebb and flow of the daily tides is constantly changing your home turf? If you're the decorator crab, you simply grab whatever sea plants you can find and use them to disguise yourself.
Anastrozole, a medication for breast cancer treatment, costs $19.20 for a box of 30 1mg tablets in Australia. In Britain, it costs $2.45.
On average, prescription medication costs four times more in Australia than the rest of the world, and it means six per cent of patients are either delaying, or just not taking necessary medication.
In an effort to capture never-before-seen footage of animals in their natural habitats, the BBC's Spy in the Wild series created robotic versions of meerkats, monkeys, and other creatures designed to blend in with their real-life counterparts. The robots are remarkably lifelike, until you remove all of their fur and reveal their inner workings.
Lower Manhattan of the 1880s was a wonderland of futuristic technology and engineering: The city's first cable car arced over the harbour. A spindly new steel bridge was forming to connect Williamsburg to the city. And on the Lower East Side, Edison was tearing up the streets to build the first permanent power station in the world.
I don't care much for cars. But even though I'm ambivalent about automobiles, I'm incredibly passionate about the hilarious radio show Car Talk. Sadly, one half of the Car Talk brothers, Tom Magliozzi, died today at 77, which sent me searching for this they made in 2008 — the first time I saw "Click and Clack" in person.
Computers may be ubiquitous now, but they were just beginning to enter the mainstream in 1990. Like any revolutionary technology, the desktop computer was viewed with more than a little scepticism by the average person. Luckily, David Neil of PBS's Newton's Apple was there to explain to a group of dubious high-schoolers that computers are not inherently evil. And he brought a two-storey exhibit to help illustrate.
If you're studying for the algebra test tomorrow or thinking about how little you use maths now after you failed it a million times in high school, here's something to melt your brain with just a tad: maths might not actually exist. It's not an actual thing of the universe, it's just something humans invented. Or is it the other way around?
The chaos of the Boston Marathon bombing is a few months behind us now, but the mechanics of the high-tech manhunt it inspired are no less awe-inspiring than they were the day they happened. PBS's fantastic NOVA series took a deep dive into the technology that went into tracking down the suspects, and it's now available to watch online for free.
Can you imagine a world where Photoshop doesn't exist? A world where we can take every picture at face value and believe that there was no airbrushing, no retouching, no nothing? I can't. Photoshop has made it impossible for me to not question what I'm seeing and at the same twisted time has also redefined my image of what things are supposed to look like.
"Hacker" is one of the most loaded internet words getting thrown around these days. To many (hi, TV news networks), the label is inherently malicious, and goes hand in hand with threats to blow up the interwebs. Others who self-identify as such, will never ever stop whining about how it means just the opposite. But are hackers of either flavour heroes? Can they be?
Things that have changed because of the internet: newspapers, magazines, porn, dating, shopping, television, movies, video games, lunch, cooking, cats, weather, pictures. Ah, you get the point. The internet has changed pretty much everything. And sometimes it creates stuff too. Like the rise of web comics.
Playing the video game Minecraft is a joke that writes itself. Ooh, look at nerds building the world they want to live in! But it's actually engaging, like playing with a digital Lego. Could it also be the ultimate educational tool? PBS's Idea Channel examines Minecraft's case for wrinkling our brain.
The easy answer: no probably not. But after being shouted out by POTUS himself at the SOTU, 3D printing is slowly, possibly, maybe creeping into a bigger deal for more than just Maker Faire-types. So the wonderful folks at PBS Off Book decided to take a closer look and answer the question once and for all. Will 3D printing change the world?
