When something, such as a plastic bucket, is broken, adults will heat it, and then let it slowly drip to the broken position and solidify to achieve the purpose of water leakage prevention.
Seeing this scene, you also began to imitate the behavior of adults when you were young, but you accidentally dropped something black on your hand because of your ingenuity (clumsiness), and suddenly you were choked to scream by a hot and sticky liquid! Even provoked parents to scold. ...
What is this black thing? Yes! It's an asphalt block, a seemingly solid thing that can be broken at room temperature or with a hammer. In our view, it is like a stone, a solid substance.
There are three main types of asphalt: coal tar asphalt, petroleum asphalt and natural asphalt. The first two kinds are artificial asphalt, mainly by-products of coal coking and petroleum distillation, and the last one is asphalt mine stored underground in natural state.
Asphalt is an organic substance, the main component is hydrocarbons, and of course it also contains some nonmetallic derivatives. Its composition is very complex, because of its hydrophobicity, it is often used for waterproof, moistureproof and anticorrosion. ...
This thing is very common in our life, such as asphalt pavement, roof and ground waterproofing. ...
It seems to be a common thing, but there is a very famous experiment about the properties of asphalt in history: asphalt dripping experiment. Since the 1927 experiment, this experiment has been going on for nearly 100 years, and it is still going on. ...
It says that asphalt looks solid at room temperature, but is it really so? Often the truth is hidden behind the appearance, while the intuition in reality is often deceptive. The asphalt dripping experiment actually tells us a truth. Seeing is not necessarily believing, intuition is the most deceptive feeling.
Thomas of the University of Queensland? Parnell, about 1920. 1927 Thomas, Professor of Physics, University of Queensland, Australia? Parnell thinks that the hard and fragile appearance of asphalt is deceptive. In order to prove to his students that solid asphalt at room temperature is actually a fluid with very high viscosity, he did an experiment to measure the fluidity and viscosity of asphalt samples. Opened a long experiment that affected all mankind for a hundred years.
Often, the requirements of scientific experiments on the experimental environment are complex and harsh, which we ordinary people can't accomplish independently, but this experiment is terrible and simple. We can replicate the same experiment at home without any high-end equipment.
At present, this experimental device is still in the University of Queensland, and a camera has been added nearby. The material of this experiment consists of a large piece of asphalt, a bell cover and a funnel with a sealed bottom. Professor parnell first melted asphalt at high temperature and let it flow into a funnel with a sealed bottom. ...
After waiting for three years, that is, 1930, Professor parnell felt that the asphalt in the funnel had completely solidified and precipitated, so he cut a hole in the bottom of the funnel, and the operation process of the experiment was completed here. The next step is to slowly flow down the asphalt. ...
Although this experiment seems insignificant, it still contributes to scientific curiosity, and its investment and duration make asphalt experiment one of the most famous experiments.
The asphalt falling experiment of the University of Queensland proved the viscosity of asphalt. Professor parnell only witnessed two drops of asphalt in his life. The first time was in 1938, eight years after the funnel was cut, and the second time was in 1947 nine years later.
Here, the witness has not seen it with his own eyes. Professor parnell didn't personally see the moment when asphalt dripped. Because there was no camera at that time, it was impossible to save this precious picture.
This experiment started from 1930 to 1947. During this 17 year, mankind is experiencing World War II. Although war has brought human suffering, it has stimulated the development of human science and technology to some extent. In recent years, human planes have been flying higher and higher, rockets have also risen into the sky, and humans have taken pictures of the curvature of the earth for the first time. ...
Unfortunately, parnell died in 1948.
Despite this, John, an honorary professor at the School of Mathematics and Physics of the University of Queensland? Under the supervision of Si Tong, the asphalt dripping experiment continued.
In the asphalt decline experiment, the year and cumulative month of asphalt decline. In 2005, Main Si Tong and the late Thomas? Parnell was awarded the Ig Nobel Prize in Physics. The Ig Nobel Prize is a spoof of the Nobel Prize, which is held every autumn. This award celebrates the most unusual and insignificant scientific achievements.
The Ig Nobel Prize is to recognize those efforts and achievements that make people laugh. Their purpose is not to ridicule, but to respect the imagination of every scientist. Therefore, the asphalt dripping experiment is definitely worthy of such recognition.
In 20 13, Si Tong of Main died, and he recorded six more declines, the last of which was the eighth decline in 2000. In 2000, people have set up cameras around the experimental equipment, but unfortunately, due to the problem of storage equipment, Si Tong missed the eighth asphalt dripping moment.
After Si Tong died, custody was transferred to Andrew? Professor White, he became the third guardian of the asphalt dripping experiment. This experiment has successfully killed two guardians. ...
This photo is the equipment of asphalt dripping experiment at the University of Queensland, and compared with the size of 9 volt battery. The ninth decline occurred at 20 14, in Andrew? This happened under the supervision of Professor White, but unfortunately, at that time, the beaker at the bottom of the experimental device dropped too much asphalt, which had affected the asphalt that was about to drop. Professor White accidentally broke the asphalt when changing the beaker. ...
This can be said to be a major mistake, which directly led to the asphalt dripping experiment at the University of Queensland. Since the establishment of the experimental device, no one has witnessed the moment of asphalt dripping.
Before the seventh asphalt drip, there will be a drip every 8 to 9 years. However, after the seventh drip, the researchers added an air conditioner where the experimental device was located to control the experiment in a constant temperature environment, so the eighth drip took 12 years.
At present, the first 10 decline of asphalt is taking shape, and it is expected to fall within 13 years from now. Now the situation of this experimental device is broadcast live every day and can be seen on the extranet. I intercepted a photo this morning.
Fat asphalt drops are forming, but it will take a long time to fall, and you will definitely see them the tenth time!
Although we didn't see the asphalt dripping from the University of Queensland, in July of 20 13, the first photographic record of asphalt dripping was born.
Following the asphalt dripping experiment conducted by Professor parnell in 17, Trinity College Dublin also conducted the same experiment in 1944, and obtained a precious picture of asphalt dripping moment in 20 13, which can be regarded as a dream of mankind.
You may think this experiment is very useful. It tells us that the viscosity of asphalt is about 230 billion times that of water and 2 million times that of honey. If you ask, do you know what's the use? Actually, it's of little use!
But it tells us a truth: seeing is not necessarily believing!
This experiment can be used to argue with girlfriends ... to convince them that what they see is an illusion!
