What is jazz?

Jazz is the name of a certain type of popular music. Originally it was American Negro music, but it has evolved into a mix of several different kinds of music from many parts of the world. One of the main characteristics of jazz is its rhythm. The jazz melody combines elements of African and European music, but its harmony comes mainly from Europe. Another characteristic feature of jazz is improvisation. This means creating something impromptu, under the influence of a momentary mood. Most jazz is played this way. Music is created as the performer plays. Jazz has changed and evolved over the years, but it has retained its core qualities.

One of the genres of music that contributed to the development of jazz was the blues. Jazz music is a third of the blues. Blues are more than half of the popular works of rock and roll. Even some American country and western music is written in blues form. The main contribution to the development of jazz was made by musicians from New Orleans. New Orleans jazz, sometimes referred to as Dixieland, combines the deep emotionality of blues and Negro religious song, as well as elements of ragtime and European folk music. Later came big band jazz, or swing music.

In the forties and fifties came what was called modern jazz. This modern jazz was more complex harmonically and melodic than earlier styles of jazz. But its most outstanding feature was its new approach to rhythm. When creating a melody, the performers used new rhythms, and the drums played in a more complex style.

Another major step in the development of jazz was the "new direction" of the sixties. This is a free form of jazz. The whole group of performers could change the tempo and speed of the piece several times during the performance without planning it in advance. This does not mean that the music is becoming disorganized: it is simply that it has become freer in spirit and manner. So you can see that jazz is a style of music that is constantly changing but retains its basic qualities.

What is tapioca?

Do you like tapioca pudding? Looking at it, you will not believe what it is made of and what was done with it before it became a pudding on your table!

Tapioca is obtained from the roots of a large shrub common in warm countries. The shrub is called "cassava" or "cassava" in English, as well as "yucca" or "mandioca".

Cassava roots contain approximately 33% starch and 67% water, and take a long time to cook food from the roots. First they are washed and cleaned, then for three or four days they are lowered into a boiler or simply into a river. They can also be ground on a grater without pre-soaking, getting a pasty mass. The pasta is either fried and eaten or dried and made into flour.

To prepare tapioca, the pounded mass is thoroughly mixed with very clean water and removed. Pure grains of starch gradually settle to the bottom, and all the dirt merges.

The starch is then extracted and re-mixed with water, a process that can be repeated four to five times. When the starch becomes pure enough, it is sprinkled on a metal dish, which is placed on a slow fire. During cooking, the starch is constantly stirred. Over time, starch forms small lumps.

Once cooked, the pure starch is called "tapioca". Now you know that the roots of the bush go through a long processing before becoming your food. Americans get most of their tapioca from Brazil, Madagascar and Java.

The pure cassava starch, not fired, is known in the US as "tapioca flour". It is used in the processing of cotton products, in the production of glue, for example for postage stamps, and for other purposes.

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Bacteria help produce nanomaterial for computers 24.07.2019

Scientists from the UK and the Netherlands have come up with a new way to get nanomaterials from graphene: mix oxidized graphene and bacteria. Their method is economical, less time consuming and also environmentally friendly compared to the chemical production of the material. The method could lead to the creation of innovative computer technology and medical equipment, according to the website of the University of Rochester.

To create new and more efficient computers, medical devices and other advanced technologies, researchers are turning to nanomaterials - materials controlled at the scale of atoms or molecules that have unique properties. One such revolutionary compound is graphene, a two-dimensional form of carbon. This thin carbon flake has extraordinary mechanical strength and flexibility and is able to easily conduct electricity. However, we cannot yet actively fold graphene in everyday life: it is very difficult to produce it on a large scale. And not only from an economic point of view: graphene obtained in large quantities is denser and loses its unique properties.

Graphene is mined from graphite, the material used in regular pencils. At exactly one atom thick, graphene is the thinnest yet strongest two-dimensional material known to science. In 2010, scientists from the University of Manchester received the Nobel Prize in Physics for groundbreaking experiments with graphene: they were able to make graphene by exfoliating graphite with a simple adhesive tape. However, their method produced a small amount of material.

To produce more graphene materials, a team of researchers led by Anne Meyer, an assistant professor of biology at the University of Rochester, started with a vial of graphite. They gradually flaked off the graphite to graphene oxide, which was then mixed with Shewanella bacteria. They left the vial of bacteria and graphene oxide overnight, during which the bacteria converted the material into graphene by removing the oxygen groups.

Graphene oxide itself is a poor conductor of electricity, but it is easy to produce. And bacteria-derived graphene is not only a good conductor, it's also much thinner and more stable than chemically-derived graphene. In addition, it can be stored much longer.

The graphene nanomaterial has many applications. It can be used to produce field effect transistor (FET) biosensors. FET biosensors are devices that detect biological molecules and can be used, for example, for real-time glucose monitoring in diabetic patients.

Bacteria-derived graphene material could also be the basis for conductive ink, which could in turn be used to make faster and more efficient computer keyboards, circuit boards, or small wires. According to Meyer, the use of conductive ink is "an easier and more cost-effective way to produce electrical circuits than traditional methods." Conductive ink can also be used to create electrical circuits over non-traditional materials such as fabric or paper.
