How long did it take to complete the Empire State Building and when was it finished?

Intended to be the world’s first 100+ story building, construction of the Empire State Building began on March 17, 1930. Construction was completed in a record-breaking 1 year and 45 days.

How long will Empire State Building last?

The earliest steel skyscrapers, like the Empire State Building, which date from the 1930s are least likely to remain standing in 7,000 years because they are constructed almost exclusively of steel, meaning they have exceptional tensile strength but are quite rigid and inflexible.

How long would skyscrapers last without humans?

After 300 years of no humans, metal structures and bridges will start to collapse because there are no humans to repaint them so they will start to corrode. Steel rods en-placed in concrete will bloat up to 3x the regular size causing many buildings to collapse.

Who was the first person to invent the light bulb?

How old was Thomas Edison when he invented the light bulb?

Edison threw himself into the challenge of developing a commercially viable incandescent light in 1878, and investors in the Edison Electric Light Company provided him with the necessary seed money. The 31-year-old inventor sought to develop not only a working bulb, but an entire lighting system powered by a generator.

When did the incandescent light bulb become more efficient?

In 1913, Irving Langmuir figured out that placing an inert gas like nitrogen inside the bulb doubled its efficiency. Scientists continued to make improvements over the next 40 years that reduced the cost and increased the efficiency of the incandescent bulb.
