In 1903, Josiah White III bought a parcel of land near Ohio Avenue and the boardwalk and built the Queen Anne style Marlborough House. The hotel was a hit and, in 1905–06, he chose to expand the hotel and bought another parcel of land next door to his Marlborough House. In an effort to make his new hotel a source of conversation, White hired the architectural firm of Price and McLanahan. The firm made use of reinforced concrete, a new building material invented by Jean-Louis Lambot in 1848 (Joseph Monier received the patent in 1867). The hotel's Spanish and Moorish themes, capped off with its signature dome and chimneys, represented a step forward from other hotels that had a classically designed influence. White named the new hotel the Blenheim and merged the two hotels into the Marlborough-Blenheim. Bally's Atlantic City was later constructed at this location.
In what year was reinforced concrete invented?
A: 1848

Modern Orthodoxy comprises a fairly broad spectrum of movements, each drawing on several distinct though related philosophies, which in some combination have provided the basis for all variations of the movement today. In general, Modern Orthodoxy holds that Jewish law is normative and binding, while simultaneously attaching a positive value to interaction with contemporary society. In this view, Orthodox Judaism can "be enriched" by its intersection with modernity; further, "modern society creates opportunities to be productive citizens engaged in the Divine work of transforming the world to benefit humanity". At the same time, in order to preserve the integrity of halakha, any area of "powerful inconsistency and conflict" between Torah and modern culture must be avoided. Modern Orthodoxy, additionally, assigns a central role to the "People of Israel".
What can Orthodox Judaism be harmed by it's interaction with?
