In nature, blue is much rarer than you might think. Sure, the sky is blue when the weather's nice, and so is the ocean. But the vast majority of plants and animals are incapable of making blue pigment. Brilliantly-coloured peacocks appear blue not because their feathers are coloured that way, but because of how they reflect light. Less than 10 per cent of the world's 280,000 flowering plants produce blue flowers, which may be why they're often a symbol of the unattainable in folklore and literature.
Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.
One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.
Artificial intelligence is infiltrating our daily lives, with applications that curate your phone pics, manage your email, and translate text from any language into another. Google, Facebook, Apple and Microsoft are all heavily researching how to integrate AI into their major services. Soon you'll likely interact with an AI (or its output) every time you pick up your phone. Should you trust it? Not always.
Even if you can correctly identify the main parts beneath your car bonnet, you probably don't know how all those complex systems work. Here are ten fantastic videos that explain the basics - made by the car manufacturers themselves. Want to know how drum brakes work? Clutch transmissions? Car suspension? 4WD? Rotary engines? You'll find all the answers here.
The rotary engine was patented in 1929 by German engineer Felix Wankel, and it could not be more different to the piston engines that exist in most of the cars on the road today. This neat video breaks down the essentials.
According to my calendar, the Australian winter is almost over yet it's still cold as buggery. This morning, I had to scrape about an inch of frost off my windscreen and then warm up the engine like some hapless Melbournian. But wait. Do you really need to warm up a car before driving or is this just an old dad's tale? This video explains what you need to know.
In 2013, a meeting of academics specialising in teaching first year undergraduate mathematics (known as the FYiMaths network) identified that the broad removal of mathematics prerequisites for many undergraduate degrees had created the biggest challenge they faced in teaching.
Apple is one of the most reputable tech companies in the world with some of the highest paid interns. Working there must therefore be a dream job, right? Wrong. Over on the career community site Glassdoor, there are plenty of complaints and horror stories from current and former Apple engineers, developers and project managers. Here are some of their chief bugbears that other businesses would do well to avoid.
Electronic engineers are emerging as important contributors to understanding of the workings of the human brain. There is a rapidly growing intersection between electronic engineering and neuroscience. As a relatively new angle of attack, this kind of research could lead to breakthroughs in medical treatments of brain disorders and artificial intelligence technology. Why is this?
