Pizza Parlors in the USA Title on X or x and remember 7 goes One Way 7 Goes the Other Way so read the Works of Leonardo da Vinci with that in Mind!!!!!!

 

Before the Crossing

Watch for these signs as you approach a highway-rail grade crossing. 

On the Road

Drivers, be alert for these pavement markings. 

Signs at the Crossing

These signs at grade crossings have important information for drivers.

Made by the Scuola di Costruzioni ed Esperienze Aeronautiche at Guidonia and donated to the Museum in 1938, the aerial screw is one of Leonardo’s best known designs, long interpreted as the earliest anticipation of the modern helicopter.

The screw is made of a spiral-shaped linen canvas arranged around a vertical mast, inserted onto a circular platform. By running on the platform and pushing the horizontal bars connected to a central mast, a number of men can operate this screw.

This project is part of the study of the physical and chemical characteristics of air: Leonardo reached the conclusion that air can be compressed and that it has its own material thickness. He therefore retained that a screw-shaped device, if rapidly rotated, could rise in flight by screwing itself into the thickness of the air, in exactly the same manner a common screw can screw into another material.

The Italian polymath Leonardo da Vinci drew his design for an "aerial screw" in the late 1480s, while he was employed as a military engineer by Ludovico Sforza, Duke of Milan from 1494 to 1499. The original drawing is part of a manuscript dated to 1487 to 1490 and appears on folio 83-verso of Paris Manuscript B [it; pl], part of the papers removed from the Biblioteca Ambrosiana in 1795 by Napoleon and still held by the Institut de France in Paris.

Leonardo biographer Walter Isaacson has expressed the belief that it was "devised for a theatrical spectacle".^[1] The "aerial screw" was one of several aerial machines drawn by Leonardo, including an early parachute, an ornithopter and a hang glider.

The pen-and-ink sketch outlines an idea for a flying machine similar to a modern helicopter, with a spiral rotor or "aerial screw" based on a water screw, but intended to push against the fluid of the air instead of water.

The design comprises a large structure, built on a hard circular platform, with a central vertical pole supported by four diagonal members meeting at a small circular plate about halfway up the pole. The upper half of the pole is the supportive axis for a large spiralling sail of linen with a radius of about 5 m (16 ft), stiffened with starch. The inner edge of the sail winds clockwise around the pole, while the outer edge of the sail is connected by ropes or wires to a ring that rotates around the lower platform. The design envisions a crew of several people on the wooden platform running around the central pole while holding handles that rotate the sail.

The Einstein-Rosen solution does not say anything about the relationship between the two regions of spacetime. One possibility is shown above. The black hole in some region of spacetime connects to a black hole in another region of spacetime. 

1. The 7 goes one Way on the Whole Pizza

The 7 goes the other Way on the adjacent Whole Pizza!

The Structure of said word BOX in the equated word THREAT is in the Structure to the Thee on the Crust of the Piece of Pizza so how many Slices is important as the Structure of the said word BOX is in word Construction.

1.  This is an example of a word BOX and has the word Outline word Material to understand the importance of the word THREAT between the Two Whole Pizzas, especially on Pi!!
