The Shape of Alpha
Using Where-On-Earth geotagged photos uploaded to Flickr, one is often able to reverse-engineer maps, sometimes even at the neighborhood level.
Over time this got us wondering: If we plotted all the geotagged photos associated with a particular WOE ID, would we have enough data to generate a mostly accurate contour of that place? [...]

10 Most Incredible Waterfalls of Ice
BP (before physics) I used to wonder how waterfalls could freeze. But if one looks at the physics, it’s apparent that the motion of water moving in a stream, river or waterfall is small compared to the thermal motion, so this motion really has little effect.
Take a peek at [...]

The Periodic Coffee Table
By embedding all element samples in clear acrylic, they are beautifully presented and also protected from tarnishing. This format also helps to addresses health and safety issues, as all potentially toxic or corrosive substances are permanently encased in a thick layer of robust resin. Argon gas and mineral oil is further used [...]

DelFly Micro Air Vehicle Weighs Just Three Grams
The ‘dragonfly’ has a tiny camera (about 0.5 grams) on board that transmits its signals to a ground station. With software developed by TU Delft itself, objects can then be recognised independently. The camera transmits TV quality images, and therefore allows the DelFly II to be operated from [...]
