There was a global survey conducted about 8 years ago.

Over 115 nations involved, with almost 7 million people surveyed. They were asked many questions on differing topics and themes

The most respected and admired people were the Greeks

The most important contributions to western society were by the ancient Greeks

You cant argue with that

Even Einstein agrees that he would rather be reading the works of the ancient Greeks than studying physics

The History of Concrete and Cement By Mary Bellis

Concrete is a material used in building construction, consisting of a hard, chemically inert particulate substance, known as an aggregate (usually made from different types of sand and gravel), that is bonded together by cement and water.

The Assyrians and Babylonians used clay as the bonding substance or cement. The Egyptians used lime and gypsum cement. In 1756, British engineer, John Smeaton made the first modern concrete (hydraulic cement) by adding pebbles as a coarse aggregate and mixing powered brick into the cement. In 1824, English inventor, Joseph Aspdin invented Portland Cement, which has remained the dominant cement used in concrete production. Joseph Aspdin created the first true artificial cement by burning ground limestone and clay together. The burning process changed the chemical properties of the materials and Joseph Aspdin created a stronger cement than what using plain crushed limestone would produce.

The other major part of concrete besides the cement  is the aggregate. Aggregates include sand, crushed stone, gravel, slag, ashes, burned shale, and burned clay. Fine aggregate (fine refers to the size of aggregate) is used in making concrete slabs and smooth surfaces. Coarse aggregate is used for massive structures or sections of cement.

Concrete that includes imbedded metal (usually steel)  is called reinforced concrete or ferroconcrete. Reinforced concrete was invented (1849) by Joseph Monier, who received a patent in 1867. Joseph Monier was a Parisian gardener who made garden pots and tubs of concrete reinforced with an iron mesh. Reinforced concrete combines the tensile or bendable strength of metal and the compressional strength of concrete to withstand heavy loads. Joseph Monier exhibited his invention at the Paris Exposition of 1867. Besides his pots and tubs, Joseph Monier promoted reinforced concrete for use in railway ties, pipes, floors, arches, and bridges.

History

The word concrete comes from the Latin word "concretus" (meaning compact or condensed),[3] the perfect passive participle of "concrescere", from "con-" (together) and "crescere" (to grow).

Perhaps the earliest known occurrence of cement was twelve million years ago, when a natural deposit formed after an occurrence of oil shale naturally combusted while adjacent to a bed of limestone. These ancient deposits were investigated in the 1960s and 1970s.[4]

On a human time-scale, lime mortars were used in Greece, Crete, and Cyprus in 800 BC. The Assyrian Jerwan Aqueduct (688 BC) made use of fully waterproof concrete.[5] German archaeologist Heinrich Schliemann found concrete floors, which were made of lime and pebbles, in the royal palace of Tiryns, Greece, which dates roughly to 1400-1200 BC.[6][7] Concrete was used for construction in many ancient structures.[8]

The Romans used concrete extensively from 300 BC to 476 AD, a span of more than seven hundred years.[4] During the Roman Empire, Roman concrete (or opus caementicium) was made from quicklime, pozzolana and an aggregate of pumice. Its widespread use in many Roman structures, a key event in the history of architecture termed the Roman Architectural Revolution, freed Roman construction from the restrictions of stone and brick material and allowed for revolutionary new designs in terms of both structural complexity and dimension.[9]

so you agree with me that being Jewish is merely another Religious denomination.

So one relinguishes their Jewishness once thy abandon the teachings of the Torah - or old testament

In fact Orthodox Jews would also agree with you

Well Done

We achieved something today Herbert

good luck

It is also a Cultural association.

Quote:


Yes they do, by accepting the tenants of their religion which often stand at odds with their old (viz, the role and identity of "the messiah" in Judaism versus that of Christianity).  However, they don't relinquish their ancestry or its associated Cultural associations.

I take that this means you admit you were wrong to claim that Karl Marx and Iosif Vissarionovich were Jews?  If so, why did you claim it in the first place?   

except for their overwhelming interest in buggery, to the exclusion of attending to their own wives
