the elevator: a way to achieve high or low positions-电梯：一种实现可高可低的方式

An old and a new kind of elevator.

An elevator (or lift in British English) is a vertical transport equipment that efficiently moves people or goods between floors (levels, decks) of a building, vessel or other structure. Elevators are generally powered by electric motors that either drive traction cables and counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack.

The first reference to an elevator is in the works of the Roman architect Vitruvius, who reported that Archimedes (c. 287 BC – c. 212 BC) built his first elevator probably in 236 BC. In some literary sources of later historical periods, elevators were mentioned as cabs on a hemp rope and powered by hand or by animals.The ancient and medieval elevators used the drive system based on hoist.

In 1852, Elisha Otis introduced the safety elevator, which prevented the fall of the cab if the cable broke. The design of the Otis safety elevator is somewhat similar to one type still used today. A governor device engages knurled roller, locking the elevator to its guides should the elevator descend at excessive speed.

So, from a steam engine the elevator improved itself in a electric functioning.

The development of elevators was led by the need for movement of raw materials including coal and lumber rom hillsides. The technology developed by these industries and the introduction of steel beam construction worked together to provide the passenger and freight elevators in use today.

sound pressure-声压

Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average, or equilibrium) atmospheric pressure caused by a sound wave. Sound pressure can be measured using a microphone in air and a hydrophone in water. The SI unit for sound pressure p is the pascal (symbol: Pa). Sound pressure level (SPL) or sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels (dB) above a standard reference level. The commonly used "zero" reference sound pressure in air is 20 µPa RMS, which is usually considered the threshold of human hearing (at 1 kHz).

Sound level meter

 

 An integrating-averaging sound level meter.

Sound level meters measure sound pressure level and are commonly used in noise pollution studies for the quantification of almost any noise, but especially for industrial, environmental and aircraft noise. However, the reading given by a sound level meter does not correlate well to human-perceived loudness; for this a loudness meter is needed.

the meter and the length-米和长度

The meter [m] is the international standard unit of length, approximately equivalent to 39.37 inches. It was redefined in 1983 as the distance traveled by light in a vacuum in 1/299,792,458 of a second.

Other units of length and their equivalents in meters are as follows:
1 millimeter = 0.001 meter [1 mm]
1 centimeter = 0.01 meter [1 cm]
1 decimeter = 0.1 meter [1 dm]
1 kilometer = 1000 meters [1km]

the Tower of Babel-巴别塔

Tower of Babel, Pieter Bruegel the Elder

The Tower of Babel, according to the Book of Genesis, was an enormous and high tower built in the plain of Shinar.

" 1 Now the whole world had one language and a common speech. 2 As people moved eastward, they found a plain in Shinar and settled there.

 3 They said to each other, “Come, let’s make bricks and bake them thoroughly.” They used brick instead of stone, and tar for mortar. 4 Then they said, “Come, let us build ourselves a city, with a tower that reaches to the heavens, so that we may make a name for ourselves; otherwise we will be scattered over the face of the whole earth.”

 5 But the LORD came down to see the city and the tower the people were building. 6 The LORD said, “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them. 7 Come, let us go down and confuse their language so they will not understand each other.”

 8 So the LORD scattered them from there over all the earth, and they stopped building the city. 9 That is why it was called Babel—because there the LORD confused the language of the whole world. From there the LORD scattered them over the face of the whole earth. "

Bible, Genesis 11

ancient chinese proverb-古中国的谚语

It happens to people who are truly wise what happens to the ears of corn: rise and raise your head straight and fair as long as they are empty, but when they are full of beans begin to humble himself and lower his head

Michel de Montaigne

"L'homme est né pour l'action, comme le feu tend vers le haut et la pierre vers le bas. Ne pas être occupé et n'exister pas pour l'homme c'est la même chose"

Man is born for action, as fire tends upwards and the rock down. Do not be busy and do not exist for man is the same thing

High Egypt and Low Egypt-高埃及和低埃及

At the time of the Ancient Egyptians Egypt was divided in two country: High and Low Egypt. 

The High Egypt enclosed all the Nile's Valley from Assuan to Heliopolis (beside the hodiernal Cairo). The Low Egypt, instead, took up all the area of the Nile's Delta. But why the Egyptians divided their land orientated themselves contrarily? The answer is because they oriented themselves to the geographical south, where the Nile rises ( Victoria Lake, in the center of Africa).

high and low Middle Ages-高和低的中世纪

The Middle Ages was a period of European history from the 5th century to the 15th century. The period followed the fall of the Western Roman Empire in 476, and preceded the Early Modern Era. It is the middle period in a three-period division of history: Classic, Medieval, and Modern. The term "Middle Ages" (medium aevum) was coined in the 15th century and reflects the view that this period was a deviation from the path of classical learning, a path supposedly reconnected by Renaissance scholarship.

Subdivisions:

Historians in the Romance languages tend to divide the Middle Ages into two parts: an earlier "High" and a later "Low" period.

high & low level of humidity-高低不同程度的湿度

Solid Poetry, a concrete developed by Susanne Happle and Frederick Moleschot, Droog Design.

Solid Poetry is part of those materials called "smart materials": a series of products which can change their structure, composition, shape or function depending on the external inputs.

In particular, this kind of concrete is able to change its surface texture when the level of humidity of the ambient increases: a simple surface will transform itself in a floral textured surface with a very astonished effect!

a new high skyscraper in Turin-都灵一座新的摩天大楼

Higher or lower than the Mole Antonelliana?

Here an italian debate related with the construction of a really high skyscraper in the town of Turin:

RENZO PIANO - «Il grattacielo non deturperà Torino»

TORINO — Sarà alto 180 metri, 14 in più della Mole Antonelliana, fino ad oggi, oltre che il simbolo, l'edificio più alto della città. Ma il grattacielo progettato da Renzo Piano per Intesa Sanpaolo, che fa litigare la maggioranza di Sergio Chiamparino e vede come oppositori la sinistra radicale, gli ambientalisti e la Lega, non sarà «un monolite che deturpa il panorama». È stato lo stesso Piano, vincitore contro i progetti di Hiroshi Hara, Carlos Lamela, Dominique Perrault e Daniel Liebeskind, a chiarirlo ieri con una lettera al sindaco. «La cartolina distribuita da chi si oppone (con lo slogan "non grattiamo il cielo di Torino", ndr) è ingannevole - ha scritto l'architetto - e fa apparire la torre come due volte più alta e più grande di ciò che sarà in realtà. Inoltre, il suo volume non sarà pieno ma movimentato e sfaccettato».

E per mostrare le caratteristiche del progetto, ora in mostra a Palazzo Madama, Piano ha mandato al sindaco disegni e schizzi, mentre si attende che in Consiglio comunale arrivi la variante al piano regolatore necessaria a realizzare la nuova costruzione nel cuore della città. La superficie del grattacielo sarà di 50mila metri quadrati, mentre il costo 350 milioni di euro.
