11 Questions to Test if You’re Good at General Knowledge

A child asks eight to 35 questions a day. But what to do when you’re an adult and you haven’t gotten answers to questions like: “Why does the flag fly at half-mast during a day of mourning?”; “Why is sea water salty and fish are not?”; and “Why does toothpaste spoil the taste of a sweet breakfast?” We are ready to help you: read the post and discover many new facts.

O awesome.club found interesting questions whose answers are sure to interest people of any age.

When it was created, the distance of a marathon was not fixed (about 40 km) and the main condition was that all athletes must run the same route. It is believed that the current distance of a marathon was decreed thanks to the royal family, who wanted to watch the race from the windows of Windsor Castle during the celebration of the Olympic Games in London in 1908. In total, the distance was increased by 2 km and 195 m. After that, the distance was modified at each Olympiad. Finally, the official distance of a marathon today is 42 km and 195 m was established in 1921 by the International Association of Athletics Federations (IAAF).

The button telephone and the calculator were produced from different devices. The latter was obtained from a cash register🇧🇷 When making calculations, only the numbers 0 and 1 were often used, so these have been placed below, to be more accessible.

Button phones were an alternative to pulse dialing. The company Bell Labs conducted a survey entitled “Human Factors Engineering Studies of the Design and Use of Button Telephones”. In it, a test was carried out with several experimental models of telephone keyboards, to find out which would be the easiest for the human being. In each group, parameters such as entry speed, low level of error and preference were evaluated.

Experimental telephone keypad designs for the “Human factors engineering studies of the design and use of telephone sets with buttons”.

Based on this result, Bell engineers invented a keyboard with a 3×3 matrix with zero at the bottom. This configuration is still used today and has also been adopted by smartphones.

The custom of flying the flag to half-mast was adopted in the 17th century by British military sailors in memory of their deceased companions. The flag was lowered as if to make room for a special flag: the invisible flag of death. The ability to match winners and losers in a battle is what highlights the greatness and power of death.

Food is a chemical process. Each product has a unique formula of molecules, which matches certain taste buds.

The presence of sodium dodecyl sulfate (SLS) or sodium lauriether sulfate (SLES) in the toothpaste not only helps the composition to produce bubbles as, for example, in the shower gel, where these substances are added, but also violates the balance. perfect between the molecules of the taste buds and our receptors. SLS or SLES weakens “sweet” receptors and destroys connections that suppress bitter taste.

Scientists at London’s Global University have determined, through studies, that the cerebellum doesn’t allow us to feel ticklish when we do it ourselves. The cerebellum is a region of the brain whose main function is to integrate sensory and motor pathways. When you tickle yourself, you can precisely distinguish the expected sensation from unexpected touches. There is a hypothesis that the function of tickling (as a lingering effect of evolution) is a notification of the presence on the skin of strange creatures, for example insects.

Sunday: Sunday in English it is translated as “day of the sun”. For many peoples, Sunday was a day dedicated to the Sun (Sun god). An interesting fact: every month that starts on Sunday has a Friday the 13th.

Initially, this ocean was called Great🇧🇷 The Portuguese Ferdinand Magellan, while leading the Spanish caravels in 1519, went in search of the Moluccas. The expedition in 1521 crossed the ocean and embarked in the Philippines. During the entire time of the voyage (four months and 4 thousand miles), according to the narrative of one of the crew members, not once did they encounter a storm, not even a weak one, so they decided to name the ocean the Pacific. However, the crew was only lucky, since, especially in the Pacific Ocean, 75% of all hurricanes on our planet are formed, some of them with speeds of up to 800 km/h. Here you can see the map of winds and marine currents.

The liquid or gas is heated from below because heat is transferred through the liquid or gas stream due to convection, as a result, the entire volume is heated, not just the top. Energy is transferred from one part of the ‘body’ to another, due to the movement of molecules.

The main engine of the respiratory system is the intercostal muscles, but the flat bony part of the chest would exclude their presence. The intensity of breathing would slow down the metabolism. The movement of such a creature would not be so long and fast. Confirmation of this is the turtle, whose shell represents the joined ribs and the ossification of the skin.

Watts do not indicate brightness, but power consumption. Previously, when there were only incandescent lamps, the luminous efficiency was approximately proportional to the consumed capacity and no one thought about the lumen. But with the emergence of new technologies (fluorescent and backlight) in lamps, they began to indicate the luminous flux in the lumen and the capacity in watts.

Fluorescent lamps consume four to five times less energy, and LED lamps, five to 10 times with a luminous efficiency equal to that of incandescent lamps.

In one liter of seawater there are about 35 grams of dissolved salt. But in blood and tissue fluids, most marine fish have less than twice the concentration of salts. But the concentration of salts in the blood and tissue fluids of most marine fish is three times lower. This creates strong osmotic pressure (pressure that occurs between solutions of different concentrations when in contact), which “sucks” water from the fish’s body. Although their bodies prevent the fluid from coming out, a certain amount of water is lost through gills, feces, mucus, etc. Replenishing this loss, fish drink seawater and “desalline” the inside of their body, eliminating excess salt, mainly through the gills, but also through the intestines. This is the responsibility of Case-Wilmer cells, in whose membranes there are special proteins that transport salt ions to the external environment.
