الذهب واستخدامه التاريخي كمخزن ثروة

While gold is used in industry, its main historical use has been as a means of
maintaining the value of wealth, usually in the form of jewelry and money. Gold,
measured and priced in a troy ounces or grams, has been used as a store of value for
at least 5,000 years. About 2,000 years ago, one troy ounce of gold might purchase a
high quality, custom-made outfit. Today, the same amount of gold would probably be
able to purchase a similar high-quality outfit, plus all of the matching accessories .

1) The traveler Marco Polo retuned from his famous expedition to the Far East with
fruit-flavored ices. We know from Marco Polo that Asians had been making fruit-
flavored ices for thousands of years, long before he reached this part of the world.
These delicacies became popular in France in the 1500s, but only among royalty.
Over the next few centuries, the process of making them evolved and eventually
cream was introduced as an ingredient. By the 1700s, people were enjoying a
dessert that was very similar to today's ice cream. It became a treat that could be
enjoyed by almost anyone, not just the rich .

2) The first wholesale manufacture of ice cream was in 1851 in Baltimore, Maryland
by Jacob Fussel. He had a dairy business that had excess cream which he decided
to add to his ice cream. Soon after that, his ice cream outsold all of his other dairy
products .

3) The making of ice cream slowly evolved for the next few decades. Manufacturing
methods and ingredients improved and refrigeration technology became cheaper
and more efficient. By the 1920s, home refrigerators and freezers became more
common. This gave the ice cream industry another boost. A problem developed
during World War I in the U.S., when most sugar was shipped to Europe and people
were therefore only allowed to buy limited amounts of it convinced the government
that ice cream was an "essential food". Ice cream factories were given sugar and
production continued .

4) Sales increased in the years leading up to World War II before leveling off in the
post-war years. The rise of giant supermarkets created a demand for cheaper,
1960s saw a resurgence in "premium" ice cream, while the following decades saw
the market fragment into low-fat varieties for the health-conscious. Including frozen
yogurt, fruit bars. ice milk, fat-free ice cream, and mass-produced ice cream, but
quality suffered. Many researchers stated that 60% of frozen desserts are ice
cream

تأثير الأعاصير الاستوائية والتوازن البيئي

Although their effects on human populations are devastating, tropical cyclones can
relieve drought conditions. They also carry heat energy away from the tropics and
transport it toward temperate latitudes, which makes them an important part of the
mechanism. As a result, tropical cyclones help to maintain equilibrium in the Earth's
troposphere, and to maintain a relatively stable and warm temperature worldwide .
