Gunpowder is the key ingredient, but as adjunct professor of chemistry John Conkling from Washington College in the US explains in this video, without chemistry, you wouldn’t have burning mixtures and without these you simply can’t have fireworks.
June 30, 2015 will officially be a bit longer than usual because an extra second, or ‘leap’ second, will be added. Here’s why…
The Martin Jetpack is set for commercial launch in 2016, and its creators believe it could transform emergency response and search-and-rescue missions. The vehicle’s latest prototype, the P12, went on display at the Paris Airshow last week, with commercial production set to begin soon. The Martin Jetpack uses ducted fans instead of jet propulsion, and comes with a top speed of 46 miles per hour. It can fly for more than half an hour, and at up to 1,000 metres, or 3,300 feet, in the air. The cost is expected to be around $150,000. See it for yourself in the video below:
An unmanned Falcon 9 rocket, carrying more than two tons of supplies for the International Space Station, exploded shortly after lifting off at 10.21am Eastern Time from Cape Canaveral.
All new technology is frightening, says physicist Lawrence Krauss. But there are many more reasons to welcome machine consciousness than to fear it. Right now, says Krauss, robots can’t even fold laundry. But when they do learn to think (which he considers very likely), then there’s also reason to believe that they’ll develop consciences.
Developers at the state-funded broadcaster have been testing “mind control” technology that allows viewers to change channels using thought power alone. The prototype tests, publicized by the BBC in a blog post, showed staff members using headsets that monitored “meditation” and “activity” to allow them to decide which program to select on a TV set. The headset could render the traditional remote control obsolete, blog author Cyrus Saihan said.
With notifications, emails, texts, voicemails, “likes”, instagram pictures and tweets, comments, tags and posts, as well as, photos, videos, headlines, blogs, subscriptions, downloads, uploads,ads, ringtones, mp3’s, apps, games, usernames, passwords, captchas, folders, files, feeds, searches and poke’s … it’s hardly surprising why we’re always so busy.
A Dutch man barely out of his teens is leading one of the most ambitious ocean cleanup efforts ever: to halve the amount of plastic debris floating in the Pacific within a decade. The man’s name is Boyan Slat, and he’s come up with a pretty ingenious way of doing it. Instead of clamoring around the globe on a never-ending junk hunt, he wants the ocean to “clean itself.”
Should you introduce the technological wonder/heroin that is the iPod and iPad to your kids? Steve Jobs wouldn’t, and for good reason too…
In a leap for robotic development, the MIT researchers who built a robotic cheetah have now trained it to see and jump over hurdles as it runs — making this the first four-legged robot to run and jump over obstacles autonomously.
The Ocumentics Bionic Lens, invented by British Columbia optometrist Dr. Garth Webb, is promising to give everyone perfect vision three times better than 20/20. The surgically inserted specialized lenses would revolutionize the eye care industry by eventually make driving glasses, progressive lenses and contact lenses obsolete, according to Webb.
