Submerged rigid repeater for Transatlantic Telephone cable
In 1956 the first transatlantic telephone cable, TAT-1, was laid. In the section connecting Newfoundland and Nova Scotia rigid electronic repeaters were included to boost the electrical signals sent through the cable. Another section of the cable connecting Newfoundland and Oban, Scotland used flexible repeaters developed by Bell Telephone Laboratories.
The J-2 Engine was used in the second and third stages of the Saturn V rocket. Five were used in the second stage and one relight-able one was used in the third stage. Each engine produced 232,250 lbs of thrust in a vacuum which pushed the Saturn V into orbit at 17,400 mph and then onto the Moon at over 24,000 mph.
On June 16th, 1963 Valentina Tereshkova ascended into space, making her the first woman to travel to space. This was an extremely major victory for women in space exploration and it took another twenty years before any other women were able to travel to space. Even today, she is still the only woman to have completed a space mission on her own.
Valentina Tereshkova was born in a small village in Russia and did not start school until she was 8 years old. She left school when she was 16 and worked at a textile factory in order to help her mother afford to care for their family. The Soviet government began selecting women to be a part of their space program and Tereshkova was chosen out of over 400 applicants to participate in the program. He family and friends did not know that she would be going to space, and she kept her plans completely secret. She was selected to pilot the Vostok 6 after 18 months of intense training and preparation.
Tereshkova is described as being a hero and an icon for gender equality, not only in Russia but around the world. After her space mission, she entered the political world and represented the USSR at many different international organizations. She also received the 'Greatest Woman Achiever of the Century' award in 2000 for all of her achievements and hardworking.
Fly 360 is a flight simulator station. People who step into this station turn into fighter pilots who are tasked with flying a plane in combat. The objective while flying is to take out enemy planes. While in the "cockpit", the people piloting have full control of the plane and they are able fly the as they please. The flying is then accompanied with real time motion where the whole cockpit moves according to how they plane moves. This allows the people inside to get a true feeling for how flying in combat feels.
Hot Air Balloon
After you pass through the flying simulators on the third floor you enter a gallery room full of airplanes. But one of the first displays is on the hot air balloon, also referred to a cloud in a bag.
Henry Cavendish discovered hydrogen in 1766 which he called 'inflammable air' and proved it was lighter than air. After reading Joseph Priestly's Experiments and Observations on Different Kinds of Air, Joseph Montgolfier started experiments. With help from his brother Etienne, they were able to successful fly small paper and cloth balloons in 1782. The Montgolfier Brothers may not have known all the physics behind the hot air balloon, but they used old shoes and rotting meat as fuel since it created a dense smoke to fill the balloon. In September 1783 they flew a balloon from Versailles so King Lousi XVI and Marie Antoinette could watch as the sheep, cockerel and duck all landed safely. This proved that traveling into the upper atmosphere was not fatal.
J A C Charles was a young scientist who began to experiment with the hydrogen gas after hearing about the Montgolfier's balloons. With help from brother Robert, a small test ballon with rubberizing the silk envelope to retain the gas, was sent off on August 27th, 1783. Charles and Robert then flew for two hours in a life size one on December 1st, 1783. Charles then flew by himself one more time before never flying again.
On display is a model of the hot air balloon that made the first human flight. The two passengers were Pilatre de Rozier, a science teacher, and Francois Laurent. They took off form Bois de Boulogne on November 21st, 1783. It was a dangerous twenty five minute ride over Paris but they safely landed in parkland near the present day Place d'Italie.
Engineer Your Future
This interactive exhibit is designed for young engineers to try to solve future world problems. The first exhibit is the Play Rugged Rovers. In this exhibit, you are to design a space rover to be used on mars. You have to draw a body design and place the wheels. The goal is for the rover to go as far as possible without flipping over or crashing. There is also a big picture game. This game is the building of systems to make our lives easier. They have two versions of this game. One of them requires you to build a power grid to keep everyone having energy. The other one is the designing of a baggage handling system to make sure people don't lose their luggage and that there is nothing dangerous inside. Finally there is Futureville. This game shows the not too distant future to show where engineers engineer in the least expected places. This exhibit is designed for teens aged 11-15 who have in interest in engineering.
Our Lives In Data
Every day more and more data is collected. Data is collected from taking pictures, morning commutes, and more of our lives are being recorded as data every day. When you look at this data is shows patterns which help us see things that we could not see before. By looking at our world through data it provides a new perspective. This collection of data is known as 'big data'.
Examples of data being collected and its use: Search histories show our fears, journey data shows how cities are growing, smartphones show where traffic jams are, social media profiles reveal a lot about our personalities, energy meters can tell when we are home. What we purchase reveals life events, ebooks can measure our reading speeds, social media posts reveal who'll win an election, and so on and so on.
There are many small interactive exhibits inside the Our Lives in Data exhibit. One of them asks you a series of questions and determines how willing you are to share information. Another just by taking your picture compares it with the other data it has received to predict your age, gender, and happiness level. There is a display on the data collected from tube stations, and one on how much data is collected through Facebook.
