Albert Einstein (March 14, 1879 – April 18, 1955) was a German-born theoretical physicist. He is best known for his theory of relativity and specifically mass-energy equivalence, E = mc². Einstein received the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect."^[1]

Einstein in 1947

Einstein's many contributions to physics include his special theory of relativity, which reconciled mechanics with electromagnetism, and his general theory of relativity, which extended the principle of relativity to non-uniform motion, creating a new theory of gravitation.......

Alice in Wonderland syndrome (AIWS), or micropsia, is a disorienting neurological condition which affects human visual perception.

An illustration by John Tenniel of Alice rapidly growing.

Subjects perceive humans, parts of humans, animals, and inanimate objects as substantially smaller than in reality. Generally, the object perceived appears far away or extremely close at the same time. For example, a family pet, such as a dog, may appear the size of a mouse, or a normal car may look shrunk to scale. This leads to another name for the condition, Lilliput sight or Lilliputian hallucinations, named after the small people in Jonathan Swift's Gulliver's......

When Ferdinand Magellan led the first circumnavigation of earth in the 16th century, his 5 ships were about 33 metres (100 feet) long, and reached 10 knots. Today, cruise liners exceed 300m (1,000ft) in length and reaches 25 knots.

Cunard's Queen Mary 2, featuring 17 decks and towering 62 metres (200 ft) above the waterline, one and half times higher than the Statue of Liberty, only 35 metres shorter than the Empire State Building.

Other beauties in the big league include the Norway, at one stage, the longest liner at 315,5 metres (1,035 feet), yet she's not in the top ten by Gross Registered Tonnes (GRT), registering 76,049 tonnes. The......

In 1897, Austrian businessman Emil Jellinek, traveled from his home in Nice, France to purchase a car from the Daimler factory in Cannstatt, Germany. On his return to the French Riviera, his sporting Daimler Phoenix caused such a sensation that he decided to enter it into a local touring competition, under the name of "Mercedes" after his favourite 9 year old daughter.

Gottlieb Daimler also agreed to having them sold under the name of "Mercedes."

This is what I want to share from shifthappens presentation. It is a good nice presntation specially for students. Students are encourage to see this presentation. I am not promoting or advertising.  

Thanks for deciding to join the conversation.

This wiki is designed to give you a little more background on the Did You Know? presentation. The wiki also will connect you with some resources to learn more about the shifts that are occurring in our world and their implications for K-12 and higher education.

Because we are educators in the United States, our experiences and perspectives are going to be somewhat America-centric. However, we believe that the themes of Did You Know? are global in nature and apply to schools and children around the world. We want all children to be successful. We do not view the growing importance of India and China as negative but rather as additional opportunities for everyone in the world. We do not mean to gloss over the very......
