Pitch drop – The longest laboratory experiment

Pitch drop – Prof. Thomas Parnell from the Australian University of Queensland wanted to show students that some substances, although they appear to be constant. In fact, they are very viscous liquids. He poured hot tar into the glass, sealed funnel . More precisely the so-called coal tar, which is forming by distillation of tar. He waited three years and opened the funnel.
The tar began to flow down at such a slow pace that only after a few years a drop formed at the end of the funnel. After a decade, it broke away and fell into the dish. This has happened nine times since 1927.

The last drop fell in 2014, another should fall in about nine years.

Pitch drop experiment conducted in Australia in 2005 got Ig Nobel. Project recognized as the longest-lasting laboratory experiment. It went to the “Guinness Book of Records”. They can even be viewed using a webcam (broadcasts are monitored by several hundred people a day).

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.

Sans Forgetica – Font that improves memory

Sans Forgetica – Font that streamlines memory – Australian researchers from the RMIT University (Royal Melbourne Institute of Technology) have found that our brain reads the fonts that it already knows more quickly, such as Arial or Times New Roman. By which, however, it remembers less content contained in a given text. Therefore, in collaboration with ethologists, psychologists and professor of typography, they have developed a font that is harder to read. Sans Forgetica called it – which in translation means more or less “without forgetting”.
The letters have gaps, are slightly tilted to the left and are in contradiction with the typical way of reading. Deciphering them requires more effort from the brain. Which activates the gray cells and forces you to stop at each word for a little longer. It improves memory and allows you to learn about 7% more information!

Andre-Marie Ampere – Thoughtful and versatile scientist

Andre-Marie Ampere – (1775 – 1836) – The ancestor of electrodynamics did not go to primary school, his father taught him alone. Ampere sent his first scientific work to the Lyon Academy of Sciences (Academie de Lyon) at the age of 13! A quiet life and urgent studies were interrupted when his father was guillotined in 1793 for the Jacobin dictatorship. Eighteen-year-old Ampere has suffered this trauma. After the period of mourning, he returned to science and spiritual work. He was interested in mathematics and physics as well as in philosophy, botany, chemistry, as well as Latin, Italian and Greek.

Son Jean-Jacques Ampere (1800 – 1864) after his father’s death finished his work. Which was to classify the sciences –

Sketches from the philosophy of science, or an analytic representation of the general classification of all human knowledge

But his greatest merit is description of magnetism and subsequent establishment of the theory of electromagnetic phenomena as the basis of electrodynamics. He also created the first magnetic coil, which became the basis for the later telegraph.

At the age of 22, he began to teach mathematics in Lyon and later became a professor of chemistry and physics. For nineteen years he taught at the Polytechnique in Paris. During his lifetime he belonged to many scientific societies and he was also appreciated abroad. Unfortunately, his financial situation did not reflect merit. He often lacked money for experiments, which delayed his work.
He spent most of his life traveling, while on one of them in Marseilles, on June 10, 1836, he died. On the gravestone, according to his wishes, engraved: Tandem felix – Finally happy.
