The problem is that it will take a really, really long time at any speed that we’re capable of generating, like tens of thousands of years to get to even the nearest stars. If we had something like a fusion drive it might be possible, though in the best case it would be a one way trip that would take most of a lifetime.

After recovering from dengue, it takes some time to get back to normal. At this time the rules should be followed carefully.
But it is not the liberation that comes when the first shock is overcome. A second exposure to dengue can be more severe than the first. Apart from this, it is very important for those who are recovering to be careful about some things. Even after recovery from dengue, besides mild fever, joint pain, muscle pain, headache, pain behind the eyes may remain.
Precautions to take after recovering from dengue-
# Keep the surroundings of the house clean. Rainwater should not be allowed to accumulate around the house. Water in tubs, discarded tires, plastic bottles, etc. can breed mosquitoes. So throw them away.
# Mosquitoes rest behind cupboards, under beds, in dark corners of the house. Keep these areas clean. Do not go for strenuous work after recovery. Rest is very important. Try to sleep on time. Just rest for a few days without joining the workplace.
# Drink plenty of water. Drink 3 to 4 liters of water throughout the day. Avoid smoking, drinking alcohol. This will make your body more weak
# Must try to eat sour fruits like lemon, currant, amlaki, amra in meals. In addition, if you can eat wheat bread instead of wheat bread, it is very good.
# During this time, you can drink bottled water because the body is weak. Drink bottled water at least three days a week. It will act as food. Try drinking different seasonal fruit juices as well.
# Boil Tulsi leaves and honey in water and drink that water on an empty stomach. Will work great. Apart from this, papaya leaf juice is very useful in this disease. You will get good benefits if you grind papaya leaves and drink that juice. Take joshti honey with it. And chew one clove every day.
# Do not ignore fever again after recovering from dengue. Consult a doctor. He can diagnose the disease and start treatment quickly.
# Every time you sleep day and night, you must sleep with mosquito nets. Most mosquitoes enter the house in the morning and evening. Keep the doors and windows closed during this time.

Dimension and dimension equation
Dimension
The index of the basic quantities present in a physical quantity is called the magnitude of that quantity. For example, velocity is a physical quantity. Its level – LT-1. It can be understood through this dimension of velocity, there are two basic equations of velocity and time.
Dimensional equation
Magnitude equation is a mathematical equation, with the help of which the magnitude of a mathematical equation can be expressed. So the equation with the help of which the magnitude of any quantity is expressed or determined is called the magnitude equation.
Determining the dimension
We need to know the dimensions of the three basic equations in determining the dimensions. They are-
Mass = M
Length = L
Time (Time) = T
Now, the magnitude of the required sum must be determined, it must be expressed through the basic sums in it. After that, if the dimensions of the basic equations are properly set, the dimensions of the equation will be found. For example-
Momentum = Mass * Velocity = Mass * (Distance / Time) = M.(L/T) = MLT-1 .
In this way, we can determine the value of any profit.

Musa Al Khawarizmi
See lessHis full name is Abu Abdullah Mohammad Ibn Musa Al Khawarizmi. He was born around 780 AD on an island near the Amu Darya in the Arabian Sea in Soviet Russia. He played a major role in Arithmetic, Algebra, Geography, Astronomy, Geometry. But he is most famous for algebra. It is known from his book ‘Al Jibar Wal Muqabila’ that he was a devoted Muslim. Al-Khawarizmi took a job in Caliph Ma’mun’s vast library. This is probably where he became attracted to science. By studying with infinite patience, he became acquainted with all the subjects of science.
He was a world famous mathematician. He took the mathematical knowledge of his time to an unimaginably richer level.
Besides being a mathematician, he was also a notable astronomer. His knowledge of geography surpassed excellence. He was the father of Algebra. He first mentioned algebra in one of his books. The name of the book is ‘Al Jabar Wal Muqabila’.
He translated many Greek and Indian texts on science into Arabic. He wrote a book on arithmetic, which was later translated into Latin. It was under him that Algebra became richer in later times. Al-Khawarizmi’s principles of mathematics are at the root of the development and discoveries in various branches of science that have been made possible with its help up to the present era. Algebra, the English name of Algebra, originates from his book ‘Kitab Al Jibr Wal Muqabila’.

Ibn Sina practiced his philosophy, practiced science, practiced all knowledge from astrology to logic, accounting, mathematics etc. At the age of only 16, he taught contemporary sages, doctors and thinkers. As a result, it is easy to understand that he was the greatest physician of that time. It is said that when Ibn Sina fell asleep from exhaustion, unresolved questions floated through his mind like dreams. The door of his knowledge would open. He woke up and solved the problem! As a famous physician his name spread everywhere. At the age of 21, he wrote an encyclopedia called Al Muzmua. In this he recorded all subjects except mathematics. Ibn Sina wrote more than a hundred books on physics, philosophy, theology, geometry, mathematics, medicine, literature, etc. He was the best doctor in the world in his time.

Jabir Ibn Hayyan
See lessFull Name- Jabir Ibn Hayyan Al-Ajdi As Sufi Al-Omabi. His father was a Haiyan of the Azdi tribe, a resident of the southern part of Arabia. He was a pharmacist from the Arab Azad tribe who migrated to Kufa from Yemen during the Umayyad Caliphate. Although he was the son of a doctor father, due to the contemporary political situation, Umayyad Caliph executed his father, but he faced extreme suffering during his childhood. Although he lived in Kufa as a child, after the death of his father, he returned to his homeland in South Arabia. There is doubt among many about the true nationality of Jabir Ibn Hayyan. Some consider him an Arab and some consider him a Persian citizen.
During his stay in Kufa, he became particularly interested in the study of alchemy. In that perspective, he also established a chemistry laboratory in Kufa. Muslim historians have called the laboratory as the first laboratory in the world. He was the first in the history of the world to invent the method of practicing the elementary processes of chemistry in a scientific manner. So he is called as ‘Father of Chemistry’. Apart from physics and chemistry, he contributed to medicine, mineralogy, philosophy, warfare, geometry, astronomy, engineering etc. He wrote about 3 thousand books. Among them, the number of medical books is about 500. His famous ‘Theory of Balance in Nature’ is mentioned in The Book on Balance.
Many important processes of modern chemistry were discovered by Jabir Ibn Hayyan. Notable among which are distillation, chelation, refining of metals, liquefaction, vaporization, hydrochloric and nitric acid synthesis. Besides, he was the first to discover the method of making steel, the method of dyeing leather and cloth. Iron rust prevention varnish is his invention. It has even contributed to hair curlers, glass, writing ink.
Jabir Ibn Hayyan divided the material world into three main parts. Spirits in the first part, metals in the second and composite substances in the third. Based on his discovery, later scientists divided the material world into different parts. He presented to the world civilization some substances which, when heated from a solid state, turn directly into vapor instead of liquid. Among them camphor, arsenic and ammonium chloride are notable. Apart from this, among pure objects, gold, silver, copper, iron, zinc etc. are notable.
Jabir Ibn Hayyan was the first to produce nitric acid. Even sulfuric acid is his discovery. He described the formula for making nitric acid in Kitabul Istitmas. He gave the name “aqua regia” to the mixture of nitric acid and hydrochloric acid to melt gold. Jabir Ibn Hayyan could make gold and precious stones. But he was not greedy for gold or precious stones. Greed and lust for wealth could not cause him to deviate from the ideals of civilization development and research.
Most of Jabir Ibn Hayyan’s writings are illegible and cryptic. It is not possible for everyone to understand what he wrote. Experts are able to understand something. He used an elaborate chemical numbering system through Takkin’s concept and the names of various substances used in Arabia at the time.
