Money is like quantum physics, the more you think about it the weirder it becomes, from the completely abstract versions of credit to 4 ton limestone Yap island coins. Money is most often based on trust, the illusion that a promise has tangible value. Here are some of the most interesting examples of money we could find, the earliest coins, credit cards and bank notes and the largest coins and checks.

Giant centrifuges are used to test whether fighter pilots or astronauts can deal with extreme G forces, pilots having 3 chances to survive a 15 second 6G test to be able to qualify. Here are some videos of the results of the effects of these tests up to 10G and on a range of suspects from pilots to Iron Maiden’s lead singer.

BASE jumping is much more interesting than ordinary skydiving, for us, because it involves architecture. Here are some videos of people jumping off notable structures, such as Notre Dame, the Eiffel Tower, Nervi’s influential Pirelli tower in Milan and the enormous Burg Dubai. We have also included a jump off the end of a blade on a wind turbine (because they are beautiful structures) and an indoor jump inside a cathedral like, converted airship hangar. The Macau tower bungee jump is notable because its a similar height to the Eiffel tower and is a legal amusement ride that anyone can pay for. Our favorite, however, is the jump off Calatrava’s Turning Torso building in Malmo, Sweden. Although Calatrava can sometimes appear willful in his focus on structure rather than space, revealing himself to be more of a creative engineer than an architect, the Turning Torso is his best work to date. Similarly the jump itself is spectacular, involving two parts: jumping from a plane onto its roof and then from the roof to the ground. In the rather obscure and narrow overlap between extreme sports and architecture this is a definitive piece.

Amazingly, the existence of the unsuccessful Soviet moon landing program was secret until the fall of the USSR. It consisted of three principal components: the N1 rocket; Soyuz 7K-L3 orbiter and LK lander.The first stage of the N1 is the most powerful rocket every built, it never launched successfully and when it blew up, it resulted in the largest non-nuclear, man-made explosion in history. All of the hardware looks similar enough to be familiar, but different enough to be slightly alien, such as the bug like lander, of which there are 5 left. All that remains of the N1 itself are a few scraps in a children’s playground in Kazakhstan, but its engine type is still in existence, used by the company that formerly owned the satellite system used by Google Maps.

I combined two types of concept plan in this list that are very different but share the fact that they show an alternate universe where airports weren’t giant fields on the edge of cities.On the one had there are the airports that literally float on water, and although these have become a reality with projects such as Kansai or military aircraft carriers, some of the original designs are for runways floating on rivers right in the middle of cities. Here the concept overlaps with the other type of floating airports: those that metaphorically float above the city on stilts – or over rather than on a river, via a structure like an overhead railroad.These concepts are not as unpractical as they appear, by using short-takeoff, quiet planes, London city airport is very close to the financial center of London and its a shame that aircraft haven’t been developed to allow some of these magnificent, early ambitions to have become a reality.

From commercial kits such as the Chaos Toy or Spacewarp, to the world’s largest ball run, the 70 foot high Energy Machine in the Hong Kong Science Museum, these complicated contraptions are a classic form of Rube Goldberg Machine.Here are a collection of videos of some of the worlds most impressive ball runs in action, including the Mark Bischoff machine that was recreated for Anthony Hopkins’ obsessive character in the movie Fracture, to one built for a one-off ending to Sesame Street.

Some of the most beautiful pieces of architecture in the world have a spiral stair as the final flourish. The spiral stair is an architects favorite, from Gaudi to Corbusier to Foster, but some of the most interesting spiral stairs are accidental pieces of architecture, such as those inside lighthouses or on giant silos and storage tanks. Here is a deliberately diverse collection of some of our favorites. Vote for yours.

    It’s a model of an abattoir after a swine flu cull.

    Its the under frame for an Elizabethan dress.

  3. Rich Says:

    its an upside down model used to design some famous church or cathedral

  4. admin Says:

    @Rich – yes.

    Does anyone know which one? The shapes formed are catenary arches which when inverted would create a very efficient structures following optimum stress lines.

    Despite the simplicity of the method, this is a rather sophisticated structural approach – far more so than gothic cathedrals which are often surprisingly structurally inelegant.

  5. rob Says:

    It’s Gaudi model for the structure of the La Sagrada Familia in Barcelona. Strings with weights – when inverted – becomes the model for the structure.

  6. admin Says:

    @Rob Spot on. The ‘unfamiliar’ item is indeed an inverted model of Sagrada Familia, Gaudi’s unfinished masterpiece in Barcelona.

  7. scott Says:

    not to split hairs, but i believe that’s gaudi’s catenary arch model for the unfinished cathedral at colonia guell outside of barcelona. the appearances of the two churches’ designs are similar in some respects, and gaudi DID use this method of representation for both, but the sagrada familia has more pronounced, elongated towers (whereas the ones on the church at colonia guell were to have a more conical appearance)

  8. admin Says:

    @Scott. Looks like you’re right. The model is in the basement of Sagrada Familia but is of the Colonia Guell .

  9. Val Hallan Says:

    It looks like the ballast bag array for a Japanese WWII transcontinental balloon bomb. I saw one at the US Air Force Museum many years ago.

  10. kreatiiv Says:

    unfinished for now…. to watch them work inside the cathedral using the traditional stone cutting techniques is absolutely amazing…. maybe one day they will actually finish it :)

  11. Gina Says:

    It’s a model used by Gaudi to create the towers and archs of the Church of La Colonia Guell of Barcelona (in Catalonia).
    Is based on the museum of La Sagrada Familia where it explain how Gaudi created his buildings :)

    it appears to be part of a “fly gallery”, the system of ropes and counterweights to suspend various theatrical scene elements backstage, hmmm.
