Most people over the age of 10 have 4 to 6 dreams every night. Those numbers times 365 days in one year makes for between 1,460 and 2,190 dreams every year. We dream during REM periods (which is when we have Rapid Eye Movement in our sleep) which can range anywhere from 5 minutes to half an hour long. In the course of one night this happens multiple times.
"Wait a minute!" you might be thinking, "I don't remember having 4 different dreams in one night, and I certainly don't remember having over 1,000 dreams this year." The fact of the matter is, you forget between 95% to 99% of all the dreams you have. That may seem kind of high, but most of your dreams don't really interest you enough to make you want to remember them.
Dreams are commonplace and don't require enough concentration to force you to remember them. In that sense, they are similar to other routine actions you do throughout the day like driving or tying your shoes. You don't remember most of the time you do those things either.

BMW used to manufacture airplanes.
The company we now know as BMW actually started as Rapp-Motorenwerke, a company that manufactured low-quality aircraft engines in a converted bicycle factory near Munich back in 1913. That company later merged with another more successful engine company called Gustav Flugmaschinefabrik, to form Bayerische Flugzeug-Werke (Bavarian Aircraft Works) aka BFW. After securing a contract with the German military they again changed names in 1916 to Bayerische Motore Werke or BMW for short. They then produced the war planes that the Germans used in the first World War.
As part of the Versailles Treaty at the conclusion of WWI, Germany was no longer allowed to produce military aircraft (though, they still did). BMW still secretly produced airplane engines but with the decreased demand for military aircraft engines and a weak post-war German economy, business was struggling. They had to branch out and produce engines for trucks, boats, farming equipment, motorcycles, and finally in 1928, automobiles.
During World War II, BMW found itself producing military vehicles and even rockets for Nazi Germany's military. Though their Munich plant was destroyed during the Allied invasion of Germany, the company survived the war, and was allowed to repair vehicles for the Allied troops during the postwar reconstruction. In the decades after the War, BMW gained international renown for its cars. However, if you look at their logo, it's actually a picture of a propeller, in reference to the company's past.

Facebook paid $8.5 million to acquire the domain name 'fb.com'.
How much money did Facebook fork over when it acquired Fb.com last year? A cool $8.5 million, more than 42 times the amount the company originally paid for Facebook.com.
In case you were wondering, the previous holder of the domain wasn't an incredibly shrewd domain squatter. It was actually held for a long time by the American Farm Bureau Federation, who owned fb.com to redirect to their actual website, fb.org. Facebook acquired the domain sometime last year from the American Farm Bureau Federation. At its annual meeting in Atlanta, the non-profit revealed that it earned $8.5 million on the sale of fb.com, according to Reuters.
The last high-profile domain purchase by Facebook was for Facebook.com, all the way back when it was known as TheFacebook. The company paid $200,000 in August 2005 to acquire the domain, 42.5 times less than what Facebook spent to acquire fb.com. While the Facebook.com purchase was expensive for the company back then, it’s an investment that has clearly paid off. The company is obviously hoping that fb.com will also pay off.

If you leave Tokyo by plane at 7 am, you will arrive in Honolulu at approximately 7:45 pm the previous day.
Due to a massive gap in time zones, Honolulu is 19 hours behind Tokyo. Subtracting the 7 hour and 45 minute flight time between these two cities gives us a trip difference of 11 hours and 15 min. Therefore, you would actually land in Hawaii more than 11 hours before you left Japan!

There are NO natural lakes in Maryland.
Despite the fact that some of its bodies of water have been named "lakes" (Lake Habeeb, Deep Creek Lake) ALL of Maryland's lakes are man made! They have all been created by damming up preexisting rivers. Technically, that makes them reservoirs. Most of them are actually called reservoirs as well (e.g. Loch Raven Reservoir).
The reason that some of these artificial lakes are called lakes and some are called reservoirs is based on their use. The ones that were created for recreational http://www.blogger.com/img/blank.gifpurposes are called lakes. If the body of water was created for hydroelectricity, flood control, or as a water supply, it's a reservoir.
Most lakes in North America were formed by glaciers, but there were no glaciers in Maryland during the last Great Ice Age. Other ways natural lakes can be made are through landslide blocking a river, or volcanic activity.

In WWII, Allied troops used FAKE inflatable 'TANKS' to trick German soldiers!
The use of “dummy tanks” made of inflatable rubber served many purposes in war time. It is effective in convincing enemy soldiers that you have more tanks than you actually do. It could also be useful as a decoy, so that you move your real tanks without being noticed. When the British and the Americans were preparing for the D-Day invasion, they used the inflatable dummies to replace their real tanks, concealing the fact of their tank movements. The Germans were fooled into thinking that the invasion was taking place from Pas-de-Calais instead of Normandy.
Inflatable tanks are still used today. The Russian military still produces blow-up tanks and anti-aircraft weapons. These inflatable tanks are much more sophisticated because they now have to trick both the human eye and thermal imaging. An inflatable T-80 tank costs $6000.

Mexico has 60 languages!
However, only 6% of the population can speak any of these indigenous languages. The Spanish colonizers forced the Spanish language to be the official language of Mexico. It wasn’t until the 1990s that Mexico accept the indigenous languages as official languages for the country. Mexican legal documents can now be written in any of the 60 languages!

Scientists used to think that Stegosaurus had a brain in its butt.
This was because it was hard to believe that the 24 foot long animal could have survived with a brain roughly the size of a walnut. This led to suspicion that the stegosaurus was so large it needed two brains to maintain its bodily functions. Part of this confusion stemmed from the fact that the stegosaurus’ spinal cord features a suspicious bulge near its rear end. This enlargement of the spinal cord in the hip area was actually its sacral plexus, an intersection of various nerves that serves the animal’s pelvis, back legs, buttocks, and genitals. None of this conspicuous nerve bulge was made up of brain matter.
Naturally, despite the fact that scientists later disproved the “second brain in its rear end” theory, it was too good for the press to let go. The theory was featured in a popular column in the Chicago Tribune in 1912, and nearly 100 years later, it hasn’t escaped the collective consciousness.

Gravity is weaker in North America than it is in Europe, East Asia, Australia, and North Africa.
This is because Earth is not a perfect sphere, and its interior mass is not evenly distributed. There are slight variations of gravitational pull depending on where on Earth’s surface you are.
In fact, you can now check to see which points on the Earth’s surface have the strongest and weakest gravitational pulls with a “gravity map”, available at BBC.com. The map is a 3-dimensional model of the earth that represents the amount of gravitational pull on a specific point on the Earth as its altitude. It uses data compiled from the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE).
GOCE is a satellite that orbits at a low altitude (the lowest ever for a satellite, at 254.9 km or 158 miles) that uses a gradiometer to detect the gravitational pull at different parts of the Earth. Because of this, the data collected from GOCE is the most accurate data on the Earth’s gravity that we have ever been able to compile. It has even been able to collect data from hard-to-reach areas like Antarctica, the Himalayas, the Andes, and Southeast Asia.
