Tectonic plates – Moving very slowly
Tectonic plates – The Earth looks fixed, but the development of our planet is still not completed,
and the earth is still working. The main reason is the movement of tectonic plates.
Plates are moving very slowly, a few centimeters per year. If will move up rapidly,
there is an earthquake. In the history of geological face of the Earth has changed several times.
With Pangea formed several continents we know today. The plates can move in several directions.
They can glide along each other, and then the friction releases huge amounts of energy in the
form of earthquakes. When the plates glide against each other, then either one plate thrusts
under the second or push against each other, causing uplift – this is how the Himalayas,
the highest mountains in the world. The plates can also move away from each other,
such as plates in the African Great Rift Valley.
VR may cause vomiting – Because of motion sickness
VR may cause vomiting – Because of motion sickness – In order to fully enter the virtual reality,
one has to deceive not only the eyes but also the other senses. This is also the reason why
many virtual reality users can cause problems with motion sickness. Then the impressions
received by the liar do not agree with the visual stimulus. In motion sickness,
the eyes see that the body is not moving, and that the labyrinth registers continuous motion,
tilting and acceleration, in the case of nausea caused by virtual reality is quite the opposite.
Eyes see the perfect simulation of space, covering the entire field of view.
However, the brain does not record any motion signals from the labyrinth or other senses.
In both cases there is a sensual dissonance that causes malaise, dizziness, fatigue,
and even vomiting.
Three most common allergies – Causes of allergy development
Three most common allergies – causes of allergy development – Regardless of what causes allergy,
it is always inadequate reaction of the body. Allergy is considered a disease of civilization.
Which affects approx. 20-30% of people, and this number is constantly growing.
Recent studies indicate that the risk of developing allergies carry the genes.
Food allergies: In the food allergy is caused primarily by protein. Allergens work even after heat treatment and after passing through the digestive tract. The spectrum of food allergies is very wide. Mostly allergic to eggs, fish, hazelnuts, milk, celery, fruit, vegetables, flour, peanuts, meat, potatoes and cocoa.
Pollen allergies: This is one of the most common types of allergies. Its occurrence is related to the flowering of plants, whose pollen is the patient’s allergen. Most often they are grass pollen, less common perennial, shrubs and trees. Sometimes the disease persists throughout the year, but during the flowering of the plant. Symptoms such as swelling of the mucous membranes, rhinitis, tearing, and breathing difficulties occur.
Animal allergies: The most common is allergy to cats, dogs, rabbits, hamsters, horses and exotic birds. Allergens in this case are skin or fur. However, allergens can also cause faeces, urine and saliva of animals.
Oldest pictogram – Presentation of concept
Oldest pictogram – Presentation of concept with image – Archaeologists in Gobekli Tepe
in Turkey have found the oldest pictogram, the representation of the concept with the image.
On one of the obelisks they discovered the drawing of a human head in the wing of the vulture
and the headless human body under the stele. Around the body are birds and scorpions.
According to experts, this is a pictorial representation of a particular event. The drawing comes
from 12 thousands years.
Probably the scene is related to funeral rituals. At that time, people buried dead in open graves,
where they left them to devour predators and scavengers.
The locals believed that the soul of the deceased would then go to heaven. Imagery about
the funeral habits of the then Gobekli Tepe inhabitants, archaeologists gain first of all from
the findings of the oldest temple complex that served as a religious center for a larger region.
