The document discusses three topics that changed the world: 1) Ludwig Wittgenstein was an Austrian philosopher who influenced logical positivism and ordinary language philosophy. 2) Cheyenne Mountain is home to a military operations center designed to withstand nuclear blasts. It has steel blast doors, springs to absorb shocks, and backup generators and water supplies. 3) Columbus's voyage connected the Eastern and Western hemispheres, introducing new crops, livestock, and gold between the Old and New Worlds.

2.  In the Film “The Day the Universe Changed:
The Way We Are” They mention that In 1450
we found a new way of pairing that would
help us navigate through earth. In 1844 the
invention that gave us computers was more
code. We as humans are curious. We came to
be as we are today because we ask questions.

3.  Ludwig Josef Johann Wittgenstein Changed
The world in many ways, He lived from 26
April 1889 – 29 April 1951.He was a gay
Austrian philosopher who worked in logic,
philosophy of mathematics, philosophy of
mind, and philosophy of language. He
inspired two of the century's principal
philosophical movements, logical positivism
and ordinary language philosophy.

4.  Cheyenne Mountain Changed the world as well it is a mountain located just outside the southwest side of Colorado
Springs, Colorado, US, and is home to the Cheyenne Mountain Air Force Station. Elevation 9,565 ft (2,915 m).The Cheyenne
Mountain Operations Center and the Cheyenne Mountain Directorate collect data from a worldwide system of satellites,
radar, and other sensors and process that information in real time., NORAD continues to conduct day-to-day operations in
Cheyenne Mountain. The Cheyenne Mountain complex traces its origins to 1956. General Earle E. Partridge, commander of
the Continental Air Defense Command, proposed construction of a new underground combat operations center to replace
the outgrown and vulnerable above-ground facility at Ent Air Force Base, Colorado.The launch of Sputnik I, the world's first
artificial satellite, on October 4, 1957, demonstrated not only the accomplishments of the Soviet Union's space program, In
response, the North American Aerospace Defense Command (NORAD) was established on May 12, 1958. The Operations
Center itself lies along one side of a main tunnel bored almost a mile through the solid granite heart of the mountain. The
tunnel is designed to route the worst of a blast's shock wave out the other end, past the two 25-ton blast doors that mark
one wall. The center was designed to withstand up to a 30 megaton blast within 1-nautical-mile. The underground Combat
Operations Center (COC) was originally intended to provide a 70% probability of continuing to function if a five-megaton
nuclear weapon detonated three miles (5.6 km) away, but was ultimately built to withstand a multimegaton blast within
1.5 nautical miles. The main entrance to the complex is about one-third of a mile (540 m) from the North Portal via a tunnel
which leads to a pair of 25-ton steel blast doors. Behind them is a steel building complex built within a 4.5 acres grid of
excavated chambers and tunnels and surrounded by 2,000 feet (600 m) of granite. Fifteen buildings, freestanding without
contact with the rock walls or roofs and joined by flexible vestibule connections, make up the inner complex. Twelve of
these buildings are three stories tall; the others are one and two stories. The outer shells of the buildings are made of
three-eighths-inch (9.5 mm) continuously welded low carbon steel plates which are supported by structural steel frames.
Metal walls and tunnels serve to attenuate electromagnetic pulse (EMP). Sensors at the North and South Portal entrances will
detect overpressure waves from a nuclear explosion, causing the valves to close and protect the complex. The buildings in
the complex are mounted on 1,319 steel springs, each weighing about 1,000 pounds (450 kg). The springs allow the
complex to move 12 inches (30 cm) in any one direction.To make the complex self-sufficient, adequate space in the
complex is devoted to support functions. A dining facility, medical facility with dental office, pharmacy and a two-bed ward;
two physical fitness centers with exercise equipment and sauna; a small base exchange and barber shop are all located
within the complex. Electricity comes primarily from the city of Colorado Springs, with six 1,750 kilowatt diesel generators
for backup. Water for the complex comes from an underground supply inside Cheyenne Mountain, deposited into four
excavated reservoirs with a capacity of 1.5 million U.S. gallons (6,000 m³) of water. Incoming air may be filtered through a
system of chemical, biological, radiological, and nuclear filters to remove harmful pathogens and/or radioactive and
chemical particles.The NORAD command center has been modernized several times over the years.

5.  In the Movie Journey of man it just describes how
we as humans have came. It shows us how
language has advanced. Where we are believed to
have came from. How we are believed to have
originated from a single African man. It explains
the expedition Spencer lead in order to show this
incredible discovery. It explains to us the routs
and steps he took in order to find out how we are
known to have came from one African man. In his
trip he collected about 2,000 blood samples in
order to match the DNA. It explains how life was
for humans years ago.

6. ◦ Columbus Changed the world more than anyone in the world. He knew of one place
that would make a person a fortune but it was in the other side of the world this
place was a group of islands in Asia that had spices like pepper. One spice was only
held in the one island and another in the world during the time. Spices were
everything they were used for medicine, to cooking. This place was secret, but he was
also attracted by more than spices. He was interested in the gold pavilion. He had
discovered the paper, compass, silk and gun powder. But there was nowhere else
where a European could trade. All trading routes had been dominated by other
countries. If European wanted something they had to go to chiro. Where they had
everything. Gold was the most expensive product. During Marcopolos time half of
earth was unknown. The maps were very un-accurate Coumbos journey changed
that. At the age of 25 Colombo set out to the west. He thought his journey would
only take a few months. But he never came back.
◦ Colombo brought it to the old world. Other products that were traded in the
Columbian trade were sheep, cattle, and pigs, goats, donkeys, and chicken. They
were brought from the old world to new. Potatoes, corn, chilipepers, coaco,
pineapples, tobacco, peanuts, many beans and the tomato. Colombo set out to
search for gold and spices but instead he found crops. Crops that were worth more
gold than the world could produce in value. He had created a new world joined by
two.
