Disappearing Spoon chapters 10,11 and 12:

Chapter 10, it starts out talking about copper and silver and their uses in everyday life and a long time ago. Then it goes into talking about Vanadium, which helps many things such as diabetes and to help spermicides, however it is not yet safe for human consumption. Then it began to talk about MRIs and gadolinium and it is useful in MRIs because of its maximum number of electrons. Something very interesting about this element is its ability to maybe be an enemy of an enemy thing with rumors or cancer! However, it does have side effects, it can cause kidney problems and may cause hard of breathing in some patients. Then it began talking about Pasteur, who was a scientist studying germs and proper- handed chemicals which later proved true, and then began talking about Domagk who was later a Chemist. This chapter started out very interesting! In chapter 11, it begins with talking about a NASA space shuttle, and the oxygen levels which can become dangerous. Then it began talking about nitrogen dangers and positives regarding space craft. Moreover, Branemark began to experiment with titanium and his findings revolutionized the prosthetic world! He figured out why the body always rejected the metal or wooden prosthesis that they wanted to put into the body. He found out that the immune system does accept titanium. Then it began to talk about taste and beryllium again, it can cause people to have a screwy sense of taste. It closed with talking about Bertrand Russel, who used facts about iodine to build a case about existence immortal souls. Chapter 12 began with describing the human brain and our need for desires, such as the periodic table creation, then it began to talk about Marie Curie! A very famous chemist who discovered radioactivity and she and her husband won a Nobel prize. They also had a daughter named Irene. After winning the first Nobel prize, Marie and her husband, Pierre Curie, began experimenting with uranium and what they discard from it. They found two new elements after a long experimental process, and then won another prize. Unfortunately, her husband was ran over by a carriage and the street and died, therefore, she only received the second prize. Marie's personal life reputation was very bad. She had an affair with a married man, and almost lost her second prize because of it. After Marie died from radiation poisoning, her daughter began experimenting and also died from leukemia, however, later her discoveries have become crucial to medical tools. Moreover, Gyorgy Hevesy also studied radioactivity. He was told to separate radioactive atoms and nonradioactive atoms in lead, which is impossible. After a lot of wasted time, he gave up. Only to then start to experiment with radium-D in the body. Hevesy made many achievements and his colleagues began to follow. Lastly, element 109 was found by Meitner and he received much honor. The element is known and will always be known as Meitnerium. This chapter was definitely more interesting in parts! I hope you all had a great break! Four weeks until Christmas break!
