WHAT IS PYTHON? FACTS THAT WILL PIQUE YOUR INTEREST

In recent years, and especially since the Covid-19 pandemic, the world of work has gone digital. Thanks to the rise of home-office and telecommuting jobs, many people are also considering learning to program, and one of the most popular, and useful, languages is Python.

Even if being a programmer is not your goal, the truth is that all professions are undergoing a transformation in which apps and Artificial Intelligence are becoming more prominent. That is why knowing even the basics of programming can be very useful.

According to data from the Inter-American Development Bank (IDB), it is estimated that by 2025 Latin America will need 1.2 million software developers to meet the demand. If you want to get started in this world, you can learn here everything you need to know about Python, including its uses and how much time you need to learn how to use it.

WHAT IS PYTHON?

Python is a programming language that has many uses, from web applications to machine learning. A programming language, in turn, is the tool programmers have to write a series of instructions (algorithms) to control the purpose of a computer system.

Although there are several programming languages (FORTRAN, Ada, Perl, ALGOL, ASP, BASIC, Java, JavaScript, and many more), Python is one of the most popular for several reasons. One is that its software is free to download and has the advantage of integrating well with all types of systems.

On the other hand, both professional programmers and beginners take advantage of the fact that it is one of the most “friendly” languages, as its syntax is very similar to that of English. This also allows shorter programs to be written than in other languages.

Also, besides having a library with different reusable codes for many tasks (which makes work easier), Python is also a good base for developers to learn other programming languages such as Java, for example xxx porno.

 

WHAT ARE THE USES OF PYTHON?

Another advantage of Python is that it is widely used in different sectors, from education and communications to science and medicine. Among its uses are web development, computer vision and image processing, video game development, robotics, autonomous vehicles, among others.

 

However, one of the areas where it is most used is in data science, since thanks to its visualisation library it is possible to create graphs and visual representations. Another interesting application of Python is in machine learning, which is the area of computer science in which systems are created that are capable of learning by themselves.

WHAT IS PYTHON?

Also, as Python is one of the easiest languages to learn, it is used around the world in introductory computer science and programming courses. For example, MIT is one of the institutions that uses it.

Finally, Python also has interesting uses in medicine. These include:
making clinical diagnoses based on medical records and symptoms, analysing data, creating models for developing new drugs, and so on.

HOW LONG DOES IT TAKE TO STUDY IT?

According to the educational website SuperProf, it is estimated that learning Python can take, on average, between six months and a year. That is, of course, if you follow a system of constant study, where you work on a daily basis with good training. In this time, you could be performing basic functions, as well as web applications or platforms.

There are several options for learning Python. The one most people use is the self-taught style, as there are plenty of resources on the Internet to get you started. However, this requires discipline and structure. If self-study is not your thing, there are also courses (even university courses) that may be an option.

 

 

 

Top 10: Scientific Predictions that Failed

Top 10: Scientific Predictions that Failed

We trust science; We owe everything to their great advances. However, he is not always successful with his ads. Here we will list the biggest failed predictions of science. Possibly, you know some and others will amaze you.

 

Times when science failed with its calculations

1.Comet Halley Would Destroy the Earth

Comet Halley passes through the earth’s vicinity about every76 years. Its passage in 1910 was predicted to be too close to destroy the earth either via the poisonous gas (it was thought to contain) or by a celestial collision. A global panic ensued, fueled by the media and alarming headlines. Packaged air became a fast-selling commodity, and a congregation in Oklahoma attempted to martyr a virgin to ward off the impending catastrophe. 

Although the earth passed through a section of comet Halley’s tail, there was no apparent effect porno français.

 

2.Excessive Smoking Hardly Causes Lung Cancer

W.C. Heuper of the Nation Cancer Institute (1954) once claimed that excessive smoking does not have a significant role, if any, in the production of lung cancer. Contrary to his statement, smoking accounts for 90% of lung cancer deaths in men and 80% in women. From 2005 to 2010, about 130659 Americans succumbed to smoking-related cancer every year. On average, 103659 Americans per year succumbed to smoking-related cancer between 2005 and 2010.

 

3.Humans Have Won Against Infectious DiseasesWe Should Stop Investing In Science

Times when science failed with its calculations

Dr. William H. Steward, while delivering a message of hope to the white house in 1967, said, “It’s time to close the books on infectious diseases, declare the war against pestilence won…..” He encouraged channeling resources towards chronic conditions like cancer and heart disease. While plagues like polio, measles, and smallpox are no longer a grave threat, the world still faces serious and sometimes novel infectious diseases like Ebola, bird flu, SARS, and MERES, to mention a few that can potentially kill populations.

 

4.Pasteurization is Absurd

Pierre Pachet, a professor of physiology at Toulouse in 1872, dismissed the theory of germs by Louis Pasteur. He went on to claim that the theory was ridiculous fiction. Today, humans still use pasteurization to kill germs in drinks and foods.

 

5.Humans Cannot Obtain Nuclear Energy

In 1932, Albert Einstein communicated his skepticism of nuclear power. He said that there was no slight indication of obtaining nuclear energy and that its accomplishment would mean shattering the atom at will. December 2nd, 1942 (ten years later), was the year of history – the initiation of the first human-made self-sustaining nuclear chain reactor.

6.We Should Stop Investing In Science

We Should Stop Investing In Science

The US senator Simon Cameron while commenting on the Smithsonian Institution in 1901, said he was tired of all things called science. He added that the government had been spending millions on science for the past few years, and that should stop. Today, science remains a crucial resource in various aspects of life, including health, agriculture, food, art, industries, and more.

 

7.Limited Astronomical Knowledge

In 1888, the astronomer Simon Newcomb predicted that humans were approaching the limit of their knowledge concerning astronomy. Since his remarks, the astronomers have attained numerous astronomical milestones, including the development of the Theory of Relativity, the discovery of Pluto, and the realization of the existence of galaxies beyond the Milky Way. Furthermore, men walked the moon and even built the International Space Station.

 

8.Lifestyle Choices Cause AIDS

Peter Duesberg, a molecular biologist cum professor at the University of California, is a key figure in the AIDS denialism movement. In 1988, Peter suggested that HIV did not cause AIDS, but lifestyle factors did. With this debunked, we know that the HIV virus causes AIDS.

 

9.X-Ray is a Hoax

In 1883, the President of the Royal Society, Lord Kelvin, claimed that X-rays would prove to be a hoax. He later on changed and had an X-ray performed on his left hand in 1896. X-rays remain an important diagnostic tool in modern medicine. In 2009, the X-ray machine was termed the most important scientific invention during a poll to mark the London Science Museum.

 

10.Surgeons Will Never Perform Brain, Abdomen, and Chest Surgeries

In 1870, the surgeon to Queen Victoria, Sir John Eric Ericson, predicted the impossibility of achieving chest, brain, and abdomen surgeries. He said, “The abdomen, the chest, and the brain will forever be shut from the intrusion of the wise and humane surgeon.” As one of the shapers of modern surgery, Sir John probably misjudged the future advances in his field.

 

 

 

COVID-19 Changes Your Brain

Patients suffering from Covid-19 are experiencing a range of effects on their brains, including loss of smell and taste, confusion, and life-threatening strokes. This has attracted the attention of researchers to study the impact of Covid-19 infection on the brain.

A comprehensive molecular study of the brain tissue from people that succumbed to covid-19 proves that SARS-CoV-2 causes profound molecular alterations in the brain, notwithstanding the absence of the virus in the brain mass. The changes the virus leaves in the brain indicate intense inflammation and disrupted brain circuits observed in Alzheimer’s or other neurodegenerative conditions. the lead author in the study, Tony Wyss-Coray, professor in the School of Medicine, confirmed the findings xnxx.

Up to a third of persons infected with SARS-CoV-2 exhibited brain symptoms like brain fog, fatigue and memory problems. Many individuals experience such symptoms long after recovering from the virus infection. However, the virus’ mechanism of causing these symptoms and its molecular effects on the brain are still unclear. The researchers deployed singer-cell RNA sequencing to study brain tissue samples from 8 patients who succumbed to the covid-19 virus and 14 control samples from those who died of other causes. Surprisingly, the study found significant changes in the brain cells and different types of cells (immune, nerve and support cells) in the brain. Across cell types, covid-19 effects resemble those observed in chronic brain illnesses and exist in genetic variants related to cognition, depression, and schizophrenia.

From the research, viral infections tend to trigger inflammatory reactions throughout the body. These inflammatory responses may cause inflammatory signaling across the blood-brain barrier and consequently trigger neuroinflammation in the brain. The study results may explain the brain fog, fatigue alongside other neurological and psychiatric symptoms linked to covid. 

A more extensive study (with nearly 800 participants) compared brain scans from the same people before and after infection with SARS-CoV-2. The scans showed tissue abnormalities and loss of gray matter in people who had the covid disease than in those who did not. The changes mainly affected the areas of the brain related to smell. Neurological experts, commenting on the publication in the journal of nature, said the findings were valuable and unique. They cautioned that the consequences of the changes are not clear. The results do not necessarily imply that people may experience long-lasting damage or that the observed changes profoundly affect memory, thinking, and other functions.

The brain images and cognitive scores of persons with SARS-CoV-2 exhibited changes between the two scans compared to those in the control group. The differences were more significant in older participants. While not all who became infected with the virus showed these differences, the group that had a prior infection on average had:

  • A diminished gray matter mass in the brain areas associated with the sense of smell (parahippocampal gyrus and orbitofrontal cortex)
  • More tissue damages in the parts linked with the primary olfactory cortex (also connected with the sense of smell)
  • A decline in entire brain volume and increase in the volume of cerebrospinal fluid
  • A significant drop in the ability to perform complex tasks – linked to atrophy in the area of the brain associated with cognition

According to the team of researchers, the potential mechanisms by which the virus infection might affect the brain include;

  • A reduced sensory input particularly related to smell
  • Immune reactions or neuroinflammation
  • Viral infections to the brain cells

 

 

Potential Life-Supporting Planet Found Orbiting a Dying Star

Astronomers have spotted a ring of planetary fragments revolving around a white dwarf star that’s 117 light-years away, suggesting there could be a habitable zone that can sustain life and waters. If this is confirmed, it would be the first time such a planet is seen orbiting a dying sun. White dwarfs are dead stars that have consumed all of their hydrogen fuel. All the stars are expected to get to this point in billions of years. Therefore, the findings will also give us a glimpse of our solar system’s future when the sun starts wearing away. 

 

A Novel Discovery 

The study was steered by Professor Jay Farihi, based at the University College London, who stated that this was the first time space scientists had detected a planetary body in the inhabitable zone of a white dwarf. The possible planet is estimated to be 60 times closer to the star than Earth is to the sun. 

In this new study, the researchers measured light from a white dwarf in the Milky Way (The WD1054-226). They analyzed information from the ground and space-based telescopes. The scientists were shocked to find marked slopes of light that correspond to 65 uniformly spaced clouds of planetary debris revolving around the star every 25 hours porno.

 

The Uncovered Mysteries 

The scientists noticed that the star’s light would dim every 23 minutes, implying that a nearby planet kept the stars in a particular arrangement. Professor Farihi explained that the moon-sized structures they observed were irregular and dusty. They appeared comet-like and not as spherical bodies. 

The team does not have a solid explanation for the absolute regularity, one passing in front of the star at regular intervals of 23 minutes. However, one of the explanations would be that the bodies are kept in an evenly spaced pattern by the gravitational influence of a nearby planet. Without this influence, collisions and friction would cause the structures to disperse and lose the observed precise regularity. 

The observation, known as shepherding, has been observed in Neptune and Saturn. The gravitational pull of these planets’ moons helps establish a stable ring structure revolving around these planets. The likelihood of having a world in the habitable zone is exciting and unexpected. 

 

A Long Way to Go

Although the researchers found exciting information, they believe that more data is required to confirm the presence of a planet. At the moment, they cannot observe the globe directly. Therefore, the confirmation can only be made by comparing computer models with further observations of the star and orbiting debris. 

Experts believe that any planet revolving around the white dwarf can sustain water and life. They estimate the zone to be inhabitable for at least two billion years from now. Over 95% of all stars will eventually become white dwarfs, including the sun. Considering that our sun will become a dwarf within a few billion years to come, this study offers crucial insight into our solar system’s future. Kudos to Professor Jay Farihi and his team.
