Machines eh? Ancient ones?
Seriously there's some stuff that's been built that is damn impossible a long time ago ....

They cut the stones using a technique called dolerite pounding and they moved the stones using roller logs, sleds, and curved cradles wrapped around the stone to make it roll like a wheel.

When mills were invented around 500BCE, they started building stone cutting mills to cut the stone into shape.

With the use of dolerite or mill powered grinders, no saw marks would form on the stones because these devices have no teeth.

The use of these devices allowed stone blocks to be mass produced which made it possible to construct multi-story apartment blocks all over Europe and Asia that were usually up to 5 stories high.

If you look at images of cities in Europe and Asia they are full of apartment blocks that have been there for thousands of years.

I was wondering how you were going to react to the Avatar, but I just couldn't resist when I found it.

... And I'm always up for some car history. 

Thanks!

The Ford Mustang is a legendary car, when the Ford GT40 was designed by Carrol Shelby in 1964 it had 2 important features that would enable it to set a speed record of 351km/h and win the 24-Hour Le Mans Race 5 times in a row:

A-390 Aluminum Alloy Cylinders - aside from using A-390 aluminum alloy engine blocks in the GT40s which were invented by General Motors in the 1950s to reduce the weight of engines while simultaneously increasing the power output of the engines by increasing heat dissipation because aluminum has better thermal conductivity than steel which allows for more fuel and air to be pumped into the combustion chamber without damaging the engine, Carrol Shelby invented aluminum alloy cylinders to reduce engine weight and increase engine power even further. In the movie Ford vs Ferrari, the Ferrari racecar stalled when trying to catch up to the Ford GT40 because its engine has a lower limit to its power output since it is only made of steel which has a lower thermal conductivity than aluminum.

Fiberglass Body - Carrol Shelby invented the fiberglass body for cars to further reduce the weight of the GT40.

The driver of the GT40, Ken Miles, also introduced his own innovations:

Aerodynamic Under-Chassis Wedges - Ken Miles invented these wedges which are placed underneath the chassis of the GT40 and near the wheels of the car to deflect incoming wind, preventing wind traps from forming and reducing drag.

Bonded Aluminum Chassis - Ken Miles invented the bonded aluminum chassis to reduce the weight of the GT40 even further because aluminum is 3 times lighter than steel but 2 times stronger.
