Why don't we fall off the bike?

Pedaling a bicycle, we never think about what forces keep us in a level position, why we do not fall. Two things keep us on the bike. The first is the rotating force, which is also called gyroscopic.

A gyroscope is a top mounted in such a way that its center of gravity remains in the same place, no matter how the gyroscope rotates. When the gyroscope wheel begins to spin, it maintains its position in space until external forces act on it. The same thing happens to a bicycle wheel when it starts spinning. The wheels remain balanced until they encounter forces that can change their direction.

The second force that helps us stay on the bike is the force of inertia. An example of this force can be observed when you are thrown to the side in a car if it turns sharply. If you start to fall off your bike, you turn the front wheel in the direction of the fall. The force of inertia aligns your position. In order not to fall, you turn the steering wheel slightly to the right, then to the left. In other words, you turn the steering wheel without thinking about it, in such a way that the force of inertia constantly keeps you in balance.

Why does gasoline burn?

Gasoline is very important in our life because it is used as a fuel for cars. Gasoline is a liquid fuel. It burns so quickly and with so much heat that it can explode. Gasoline is a mixture of hydrocarbons, substances consisting of carbon and hydrogen. These substances are light liquids boiling at low temperatures. Carbon and oxygen are attracted to each other, like a magnet and iron. When carbon and hydrogen combine, ignition starts. During combustion, a lot of energy is released in the form of heat.

When gasoline burns, hydrogen combines with oxygen to form water vapor. Carbon reacts with oxygen to form carbon dioxide. How does burning gasoline make a car move? Liquid gasoline turns into steam and mixes with air using a carburetor. This mixture enters the cylinder, where it is compressed by a piston moving inside the cylinder.

When the mixture of gasoline and air vapors is compressed, the spark from the spark plug ignites the fuel. A large amount of gas is produced in this small explosion (rapid combustion). The pressure of this gas acts on the piston and moves it inside the cylinder. The piston is connected to a crank that turns easily. The push received from the combustion of gasoline causes the crank arm to turn. This lever, in turn, is connected to the wheels. He sets them in motion.

The gasoline we use is made from crude oil. In the process of distillation, oil decomposes into different parts, one of which is gasoline.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

The solar system was at the center of a dark matter hurricane 13.11.2018

Astronomers from the University of Zaragoza, King's College London and the Institute of Astronomy in the US believe that the solar system is right in the middle of what is called a dark matter hurricane.

Dark matter is a hypothetical form of matter and one of the biggest mysteries of the universe. Dark matter does not emit or interact directly with electromagnetic radiation, making it difficult (or even impossible) to detect directly. Therefore, scientists rejoice at any indirect evidence of the presence of dark matter.

This time, astronomers using the Gaia satellite managed to detect the S1 stellar stream, which contains 30 stars. These stars were once part of a galaxy that was swallowed up by the Milky Way. The stream is interesting because its stars rotate in the direction opposite to the direction of rotation of the solar system. Scientists suggest that this happens because dark matter moves along with the stars in this stream.

Having considered various models of the density and distribution of dark matter in the S1 stream, the scientists suggested that there is a possibility of detecting axions - hypothetical particles of dark matter, they should be 500 million times lighter than an electron. "Ultralight particles that we cannot see can be converted into photons that we can detect in the presence of a strong magnetic field," the scientists noted. At the moment, this has not been possible.
