DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!
The field of panoramic photography needs some better terminology, IMHO: “360-degree panorama,” it seems to me, could just as easily apply to a circular panorama of, say, the horizon, as it could to a fully spherical panorama that also includes up, down, and every other direction in space you could possibly look from a particular point. Or maybe the term is already out there and I just couldn’t figure it out? If you’re in the know, please share below.
By George Hart for the Museum of Mathematics I believe that in the future, 3D printing machines will commonly be used to make household parts, e.g., when you need to fix a broken appliance knob or handle. I put this into practice recently when I needed a replacement light dimmer knob and decided to make […]
According to the New York Times article, “It May Be a Sputnik Moment, but Science Fairs Are Lagging“, fewer students may be participating in science fairs because there’s not enough time in school to do science. An education policy that aims to produce greater interest in science and technology is increasingly at odds with a […]
Built mostly from Lego Technic elements by Brickshelf user barman, who credits the idea to a model displayed at Brickfest 2006 by one Jason Allermann. Looks like it can’t really expand that far. Still cool, though.
The MBTA uses a Korean War-era jet engine mounted on a train to keep a short section of the Mattapan line clear of snow.
So-called “air batteries,” in which one of the reacting chemical species is atmospheric oxygen, are already widely employed, for instance, in hearing-aid batteries, which are commonly zinc-air cells with a piece of adhesive film that must be removed before use to allow atmospheric oxygen onto the cathode.
Made from an ordinary fiberglass satellite dish, it is covered in about 5800 3/8″ (~1cm) mirror tiles. When properly aligned, it can generate a spot the size of a dime with an intensity of 5000 times normal daylight. This intensity of light is more than enough to melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant. It stands at 5’9″ and is 42″ across.
