Fort Jefferson – Florida, USA – In left fortress-reserve

Fort Jefferson – On the Florida Keys, it was supposed to be a fortress for eternity, but life verified these bold plans. It gave shelter to soldiers for only a few years. This is one of the most ambitious construction projects in US history: thousands of workers worked on the Garden Key island. Who used nearly 16 million bricks for nearly 30 years to build the largest fort on the American coast. It was built on a hexagon plan, its walls were 14 m high, and the space in it was enough for: 450 cannons, 1500 soldiers.

The problem was that the fortress was named after President Thomas Jefferson. Most of the time it was simply unnecessary. That is why the government began to use it as a place of isolation for political prisoners in the Civil War. That was until 1867.
When an epidemic of yellow fever broke out in the fort. One of her first victims was a prison doctor. So, to stop the rampant disease, he began, Dr. Samuel Mudd – serving life imprisonment for participating in the plot for the life of Abraham Lincoln. He succeeded: he saved hundreds of prisoners and guards. Mudd was pardoned and the prison was soon closed.

Today there is a bird sanctuary in the abandoned fortress. It is also one of the favorite diving spots on the Florida Keys.

Hashima – Kyushu, Japan – Island is hell

Hashima – Kyushu, Japan – Five kilometers from the coast of Japan in the Kyushu region. An island emerges from the water that resembles, a rather powerful ship. No wonder Hashima is called Battleship by local residents. Or Ghost Island – because hundreds of people were killed cruelly. From the end of the 19th century, there were Mitsubishi concern mines. In which underwater coal seams were exploited.

During World War II:

Chinese and Korean forced laborers came to this Japanese island. As a result of inhuman living conditions and over-work. Almost 1,300 prisoners died here.
Later, workers came voluntarily, and the island itself expanded.
Reaching a length of 480 meters and a width of 160 meters. At its peak, this allowed over five thousand people to live there. With the cessation of mining in 1974, the inhabitants hurriedly left the island.

Despite the ideas of transforming island into a tourist attraction. Severe weather conditions and high costs of reconstruction, mean that only gloomy ruins threaten there – and the secrets hidden in them…

Great Sphinx in Giza – Egypt

Great Sphinx in Giza – Egypt – Archaeologists discover centimeter by centimeter of the Sphinx itself and its surroundings. Ramps appeared before their eyes, from which through the gate entered the corridors of monumental temples . One of them is directed directly towards the Chefren Pyramid. The pharaoh’s funeral scene suddenly becomes clearer. Did they carry the mummy before the Sphinx? Did they bring before the death gate to the Sphinx Temple for the last goodbye? That’s what most scientists assume.

The canals dried up, and Giza was covered with sand.

It is not clear where the corridors leading from the temple end. Most of them are covered by sand. Just like the Sphinx 150 years ago. After the last funeral in the Giza necropolis, the real end of the world took place here. Workers left the construction site in the middle of work. The canals on which the boats previously sailed dried up. According to geologists, the sphinx sank into the swamp a few meters. The rest did the sand.

Curiosities:

  • To this day, it was not possible to determine what the ancient Egyptians called the Sphinx.
  • The ancient sphinx was invented by ancient Greeks. Apparently it comes from the Egyptian word “szesepankh”, meaning “living image”.
  • Egyptian Arabs used the term “Abul-Hol” for the Great Sphinx in Giza, which means “Father of fear”.

Gary Gabelich – Exceeded by car 1000 km/h in 1970

Gary Gabelich – Exceeded with „Blue Flame” 1000 km/h in 23.10.1970. The average speed was 1001.011968 km / h. Mile, which is measured the speed of the vehicle must overcome two times: back and forth.
The big shiny „The Blue Flame” to save fuel even more. Was pushed by the service car at the start. It further helped him to accelerate to 60 km / h.
During the first run, Gabelich achieved a speed of 993.722 km / h as a result. He drove in the opposite direction, but a little faster – that’s why the speed was 1009.305 km / h.

Until then, records were set with jet engines.

„The Blue Flame” rocket engine was powered by a combination of hydrogen peroxide, and liquid natural gas. Chilled to a temperature of -161 degrees Celsius. As a result, achieved 58 000 HP.
In this way, the engine was running with maximum thrust for 20 seconds. „Blue Flame” was similar to a rocket, except with additional catches at the front and rear for attaching wheels.
Tires, specially designed by Goodyear, had a rather smooth surface to reduce heat.
The vehicle was 11.4 m long and 2.3 m wide. He weighed 1814 kg, with fuel – 2994 kg. One of the biggest troubles just before the start. There was burning through the engine, braking parachute ropes. If you had to stop the car with only disc brakes. You would probably need stretch, a 19 km length.

„The Blue Flame” designed and built by Reaction Dynamics.

With the help of the Illinois Institute of Technology lecturers and students. Dr. T. Paul Torda and Dr. Sarunas C. Uzgiris, professors at IIT, worked on the aerodynamics of the car. While other IIT students and lecturers, they mainly dealt with:
– construction,
– engine,
– steering system,
– brakes.

The speed record broken at Bonneville Salt Flats in Utah, USA.

This place is located 160 km west of Salt Lake City. Because 32 thousand years ago there was a huge lake 305 m deep. After it disappeared and the salt substrate hardened. It was created one of the most noteworthy places on Earth, to develop enormous speeds.

Gary Gabelich (29.08.1940 – 26.01.1984)

– During 43 years of life, this Croatian by origin. First of all, he won races, and set speed records on:
– asphalt,
Earth,
– water (motorboats),
– salt tracks.

He died on a motorcycle on the streets of Long Beach in January 1984. While working on the design and construction of a vehicle capable of reaching supersonic speed (1225 km / h). Prototype named „American Way”, but because of Gabelich death. Work on it canceled.

World journalists – Committee to Protect Journalists alarm

World journalists – At the end of 2018, 251 journalists were held in prisons in relation to their work. Most of them are serving judgments for anti-state activities, such as belonging to groups considered to be terrorist in a given country. As many as 28 have been punished for allegedly spreading fake news. Committee to Protect Journalists (CPJ), an international non-governmental organization claiming the rights of representatives of this profession. Alarms that independent journalists are exposed to legal sanctions. The situation in Turkey, China and Egypt since 2016 is tragic. Only these three countries are responsible for more than half of the cases of detention of media workers.

Maintain concentration – Understand performance

To maintain concentration on highest possible level, you need to understand the rhythm of your performance

Explains the researcher attention, Karl Westhoff. The results show that most people most efficiently work between the hours of 9 and 12. The second so-called top falls on the time from 15 to 17. Psychologists advise to spend the time on the most difficult tasks. The period of slump, that is from 12 to 15, is perfect in turn to a less demanding tasks. Because people have different biorhythms, everyone should be the same test.
