7- The Pratt & Whitney R-4360 Radia Engine
In 1940 the Pratt & Whitney Corp. started development of what would prove to be the largest, most complex, and most powerful aviation piston
engine ever ever built. This engine was built during the WWII but when the war was over none of these engines could be used for combat aircraft. It
did, however, power the last generation of large piston-engined aircraft before the turbojet and turboprop took over, these includes: the Boeing B-50
Superfortress, Convair B-36 Peacemaker, Martin AM-1 Mauler, Douglas C-124 Globemaster, and Boeing C-97 Stratocruiser. The Wasp Major was also used in
a number of experimental aircraft that did not reach production status, such as the Republic XP-72, Goodyear F2G, and Northrup XB-35 Flying Wing.

6-The Aeternitas mega 4 watch
36 complications, 25 of them visible, 1,483 components, a 1000-year calendar, a price tag of 2.7 million dollars, and 5 years’ work; 99
The glass sapphire case back enables the harmoniously chiselled and decorated pieces that overlap to be admired in a stunning combination as a
dazzling ballet. This masterpiece of complications and know how was entirely designed and manufactured by the Franck Muller group and once again
demonstrates their vast array of skills and ability in the Art of HAUTE HORLOGERIE.

5- Tianhe-1A computer
Tianhe-I, Tianhe-1, or TH-1 is a supercomputer capable of an Rmax (maximum range) of 2.566 petaFLOPS; that is, over 2½ quadrillion (thousand
million million) floating point operations per second, or FLOPS. Located at the National Supercomputing Center in Tianjin, China, it is one of the
fastest computers in the world and one of the few Petascale supercomputers in the world.
In October 2010, an upgraded version of the machine (Tianhe-1A) overtook ORNL's Jaguar to become the world's fastest supercomputer, with a peak
computing rate of 2.507 petaFLOPS.
Both the original Tianhe-1 and Tianhe-1A use a Linux-based operating system.
Tianhe-1A is using 7,168 NVIDIA Tesla M2050 GPUs and 14,336 Intel Xeon CPUs consuming 4.04 megawatts.

3- The Appollo Command Module
The command module's inner structure was an aluminum "sandwich" consisting of a welded aluminum inner skin, a thermally bonded honeycomb core, and
a thin aluminum "face sheet".
The central heat shield consisted of 40 individual panels interspersed with several holes and openings for the reaction control engines and
after-compartment equipment access.
The central compartment structure consisted of an inner aluminum face sheet with a steel honeycomb core, a glass-phenolic ablative honeycomb heat
shield, a layer of q-felt fibrous insulation, a pore seal, a moisture barrier, and a layer of aluminized PET film thermal strips.
The aft heat shield consisted of four brazed honeycomb panels, four spot-welded sheet metal fairings, and a circumferential ring.
The fairing segments were attached to the honeycomb panels and ring with conventional fasteners. The steel honeycomb core and outer face sheets were
then thermally bonded to the inner skin in a giant autoclave. The aft heat shield is nearly identical to the central, with the exception of the outer
alluminized PET film layer.

2- The Large Hadron Collider
The LHC, the world’s largest and most powerful particle accelerator, is the latest addition to CERN’s accelerator complex. It mainly consists
of a 27 km ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.
Inside the accelerator, two beams of particles travel at close to the speed of light with very high energies before colliding with one another. The
beams travel in opposite directions in separate beam pipes – two tubes kept at ultrahigh vacuum.
They are guided around the accelerator ring by a strong magnetic field, achieved using superconducting electromagnets.
These are built from coils of special electric cable that operates in a superconducting state, efficiently conducting electricity without resistance
or loss of energy.
This requires chilling the magnets to about ‑271°C – a temperature colder than outer space! For this reason, much of the accelerator is connected
to a distribution system of liquid helium, which cools the magnets, as well as to other supply services.
Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator. These include 1232 dipole magnets of 15 m
length which are used to bend the beams, and 392 quadrupole magnets, each 5–7 m long, to focus the beams. Just prior to collision, another type of
magnet is used to 'squeeze' the particles closer together to increase the chances of collisions.
The particles are so tiny that the task of making them collide is akin to firing needles from two positions 10 km apart with such precision that they

1- The Space Shuttle
The space shuttle has more than 2.5 million parts, including almost 370 kilometers (230 miles) of wire, more than 1,060 plumbing valves and
connections, over 1,440 circuit breakers, and more than 27,000 insulating tiles and thermal blankets.
In 8 ½ minutes after launch, the shuttle accelerates from zero to about nine times as fast as a rifle bullet, or 28,002.6 kilometers per hour (17,400
miles per hour), to attain Earth orbit.
