Me blog experience

The time has come to say goodbye to the subject, therefore also the blogs of each week that accompanied us during this semester.
My experience with these blogs was fun, at the beginning of the course when I heard about them I didn't know very well what they were going to be but I didn't expect much from them.
It was interesting because of the different topics discussed in the blog one could know more about his classmates.
Some topics were not to my liking because I did not know how to start the post since I did not feel identified with the subject so it was difficult for me to be able to generate an idea for the post.
It would be interesting to leave a blog-post of free choice for each classmate to talk about what they like and know more about each other's tastes.
In addition, these post-blogs helped me a lot to improve my writing in English and realize that my shortcomings in my vocabulary.
I finally hope that for everyone it has been a pleasant experience as it was for me, and I liked to know a little more about each one of you!

schizophrenia

What is Schizophrenia?
Schizophrenia is a chronic and severe mental disorder that affects how a person thinks, feels, and behaves. People with schizophrenia may seem like they have lost touch with reality. Although schizophrenia is not as common as other mental disorders, the symptoms can be very disabling this mental disorder affects more than 21 million people worldwide.
what is the cause?
The causes of schizophrenia are not known, but it is thought that variation in multiple genes contributes to the risk of developing this mental illness, the brain chemistry and the development also contribute to the development of this mental illness.
Signs and symptoms of schizophrenia include false perceptions called hallucinations. Auditory hallucinations of voices are the most common hallucinations in schizophrenia

Are males or females more likely to get schizophrenia?
Schizophrenia affects men and women equally but men tend to experience symptoms earlier than women.
why i chose it?
I chose this mental disorder because I was struck me by the case of John Nash what was an american mathematician who was awarded witch the nobel prize in economic. i discovered this case for the famous movie "A Beautiful Mind" a beautiful movie that tells the life of this mathematician.
but he never let this mental illness get in the way of his investigations, whenever he was interned (because of his illness) and recover the sense of reality he returned to his investigations until he had a relapse in this mental illness.

The most enjoyable subject.

organic chemistry laboratory:

i really like put into practice what one learns theoretically in class. the lab work is pretty entertaining, i always enjoyed all type of laboratories for example, laboratory of physics, chemistry, especially the latter. in the university is quite different the activity of laboratory because in the school never used dangerous chemicals but in the laboratories of the university one works with many acids dangerous.
so far I have had 3 laboratories at the university and the most entertaining is the organic chemistry laboratory because in this lab, one works alone and the teacher only solves doubts.
what i do in this lab is working witch different type of organic compound and produce chemical reactions, with which one produces different compound, the hardest of this subject is that one not have the all knowledge of the chemistry organic because, one have this lab at the same time that chemistry organic but as one progresses in the subject, one understands what one is doing in the lab.
the teacher and assistants who teach this subject are very good teaching and friendly so the labs are not difficult.

Dmitri Mendeleyev and the periodic table



Dmitri Mendeleyev was born in Tobolsk, Russia, on February 8, 1834. was a chemist and inventor. Mendeleyev is best known for his discovery of the periodic law and for his formulation of the periodic table of elements. He died in St. Petersburg, Russia, on February 2, 1907.

As he began to teach inorganic chemistry, Mendeleev could not find a textbook that met his needs, so he set out to write one " The Principles of Chemistry, but the work most famous was the creation of the periodic table that is still used today. It was when he wrote his book that he discovered similarities in the progression of atomic weights, and wondered if other groups of elements exhibit similar properties.

what impresses me about him was that when presenting the periodic table he left empty boxes for elements that had not yet been discovered but he had foreseen his atomic weigth and properties. time after this was demonstrated by the chemical Lars Fredrik Nilson when he discovered a element that completed the empty boxes.
