Question: The problem of the direction of time arises directly from two contradictory facts. Firstly, the fundamental physical laws are time-reversal invariant; if a cinematographic film were taken of any process describable by means of the aforementioned laws and then played backwards, it would still portray a physically possible process. Secondly, our experience of time, at the macroscopic level, is not time-reversal invariant. Glasses can fall and break, but shards of glass cannot reassemble and fly up onto tables. We have memories of the past, and none of the future. We feel we can't change the past but can influence the future.
Is there an answer to this question: How is our experience of time at the macro level?

Answer: not time-reversal invariant


Question: Though the true dimensions of species diversity remain uncertain, estimates range from 2.6–7.8 million species with a mean of 5.5 million. This probably represents less than 20% of all species on Earth[citation needed], and with only about 20,000 new species of all organisms being described each year, most species likely will remain undescribed for many years unless species descriptions increase in rate. About 850,000–1,000,000 of all described species are insects. Of the 24 orders of insects, four dominate in terms of numbers of described species, with at least 3 million species included in Coleoptera, Diptera, Hymenoptera and Lepidoptera. A recent study estimated the number of beetles at 0.9–2.1 million with a mean of 1.5 million.
Is there an answer to this question: How many new species of all organisms are discovered each year?

Answer: 20,000


Question: France's major upscale department stores are Galeries Lafayette and Le Printemps, which both have flagship stores on Boulevard Haussmann in Paris and branches around the country. The first department store in France, Le Bon Marché in Paris, was founded in 1852 and is now owned by the luxury goods conglomerate LVMH. La Samaritaine, another upscale department store also owned by LVMH, closed in 2005. Mid-range department stores chains also exist in France such as the BHV (Bazar de l'Hotel de Ville), part of the same group as Galeries Lafayette.
Is there an answer to this question: What are two main department stores in France?

Answer: Galeries Lafayette and Le Printemps


Question: Freemasonry consists of fraternal organisations that trace their origins to the local fraternities of stonemasons, which from the end of the fourteenth century regulated the qualifications of stonemasons and their interaction with authorities and clients. The degrees of freemasonry retain the three grades of medieval craft guilds, those of Apprentice, Journeyman or fellow (now called Fellowcraft), and Master Mason. These are the degrees offered by Craft (or Blue Lodge) Freemasonry. Members of these organisations are known as Freemasons or Masons. There are additional degrees, which vary with locality and jurisdiction, and are usually administered by different bodies than the craft degrees.
Is there an answer to this question: Where did Freemasonry end?

Answer:
unanswerable
