Engine startup LiquidPiston has radically shrunk a go-kart engine, but it's the military applications that has everyone really excited.

Physicists have just published a new paper that suggests the controversial EM drive - or electromagnetic drive - could actually work, and doesn't defy Newton's third law after all. In case you've missed the hype, here's a quick catch-up: a lot of...

Bill reveals the stunning engineering underlying the design of a diaper. He describes the five layers of a diaper, including the superabsorbent polymer in the diaper's core. He illustrates the action of this polymer with a stunning demonstration using a single bead of polymer: it soaks up enough water to grow from a diameter of 4 mm to nearly a half inch.

Bill describes the Alignment Optical Telescope used in the Lunar Module on the Apollo missions to the moon. This telescope took star sightings which were used to align the Module's guidance system. Bill shows how the telescope used an Archimedes spiral inscribed on its eyepiece to replace the heavy motors, worm gears, and rigid tracks used in a traditional sextant -- this shaved weight from the Lunar Module and allowed it to carry more fuel.

Informal ‘desire paths‘ can form with as few as fifteen traversals of an unpaved route, creating spontaneous new trails shaped by pedestrians effectively voting with their feet. These paths frequently become self-reinforcing... By Kurt Kohlstedt.

German researchers have recreated the glider flown by aviation pioneer Otto Lilienthal. By Alex Davies.

That's what their inventor Lee Eyerly intended them to be, anyway.

Representative of water conservation and life-fostering processes found in nature, the project seeks to introduce the community to everyday biological events often absent in urban environments.

Nice work, Reddit user.

Dirt is probably the cheapest and simplest construction material out there, but it's not very strong compared to other choices. Luckily geotechnical engineers have developed a way to strengthen earthen materials with almost no additional effort - Mechanically Stabilized Earth (aka MSE or Reinforced Soil). If you look closely, you'll see MSE walls are everywhere.

Gianluca asks people to draw bicycles from memory, then makes them.

In this project, I use those little magnets that can be used to make cubes and others geometric figures, I think the name is "Neocube". It's really impressive how many tricks you can do with that, at the beginning I didn't think that I could make a whole project based on those magnets, but finally, it was pretty easy and I think there is still lots of cool tricks to discover!

This article explore smartphone applications for Engineers. 8 different sensors inside the cell phone allows tons of measurement and analysis opportunities.

Updated: June 2012 Shipping themes in many forms have long been popular movie subjects, encompassing many genres including swashbuckling pirates, fantasy, historical epics and war.

showcased at the stone island ‘craftworks’ exhibition for milan design week 2016, each bicycle by luca agnelli is put together with a frame and 1950s tank, and then modified to fit the accessories chosen.
