The launching of a ship after smashing a bottle of champagne against its bow is an iconic ritual. It is also one of the few things in life which is still impressive despite being relatively slow. Shown here are videos which are interesting because of the ships fame, sheer size or quirkiness of the launch, including those where huge waves drench onlookers. Our favorite is the time lapse submarine launch in a floating dock.

Historically, military rations, comprised, in significant part, of cigarettes and alcohol, while the quantity of food was far less than today. Current US army field rations are ready to eat and focus on high energy foods including caffeine-infused gum, they must cost less than $7.25 per meal, survive for 3 years at 27 degrees C and after a 100 foot drop.Civilian rations are often far less bountiful, such as WW2 food rations current Cuban rations or the tiny hunk of bread that Gulag prisoners were given. Vote for which items are most striking.

Although the term galvanometer is often used to refer to things other than devices which measure electrical current (such as charge or resistance), there are an amazing array of early designs for this instrument, considering their simplicity.Many of these design differences are to do with the cases that surround what is basically a twisting wire, however there is something definitively analog in their mechanism and 19th century amateur scientist in their variety. Early galvanometers represent the extreme opposite of todays high energy physics, which requires giant multi billion dollar apparatuses and extreme digital processing for measurement. A long way off a compass and a battery.

Inflatables are an obvious choice for space vehicles and satellites, a small sized payload than can be inflated once up, yet for some reason they aren’t the norm.The first passive communications satellites were inflatable spheres, such as the Echo series, which mylar was developed for, and early prototypes for space stations were inflatable. More recently, funding for the inflatable replacement for the habitat unit on the space station was cancelled and a private company Bigelow Aerospace is now the pioneer in the field, having successfully launched an inflatable unit.My favorite in this list, however, is the grid sphere satellite which replaced the Echo ones which didn’t stay up long becuase the suns heat would deform them and slow them down. A helium inflated plastic balloon expanded a signal reflecting hollow geodesic mesh, with the plastic then dissolving under the suns rays. The mesh could then stay up for 11 years or so.

The original wireless network used pigeons. One of the worlds largest information firms, Reuters actually started out as a messaging service with carrier pigeons, they were used widely for messaging during the WW1 and even for aerial photography. The famous psychologist, Skinner worked on a guided missile which was to be controlled by live pigeons.

Ten beautiful computers

They ended their lives as museum pieces, aquariums, couches, and even at the bottom of the sea. But these are the ones that stay with us.nbsp; ZX Spectrum Flashes of prismatic color on Clive Sinclair’s tiny ZX Spectrum mark the original from its vast army of clones.

    Wow,one of my best friends owned one of these,it was his favorite vintage rig.He went on to be the code monster in our organization-Burgertron 2000(linked here).
