today’s birthday: Glenn Seaborg (1912)


Glenn Seaborg (1912)

In 1940, American chemist Glenn Seaborg and his colleagues discovered plutonium. He soon joined the Manhattan Project and was instrumental in the development of the atomic bomb, which he unsuccessfully pressed President Truman not to use on civilian targets. In 1951, he and Edwin McMillan shared the Nobel Prize in Chemistry for their work on transuranium elements. During his lifetime, Seaborg held dozens of patents—among them the only patents ever issued for what? More… Discuss

Quicksilver


Quicksilver

Quicksilver, commonly known as mercury and represented in the periodic table with the symbol Hg, is a chemical element with an atomic number of 80. A heavy, silvery, transition metal, mercury is the only elemental metal that is liquid at room temperature. It is used in thermometers, barometers, and other scientific apparatuses. Due to the toxicity of the element, however, the use of mercury in thermometers has been largely phased out in the interests of health and safety. What has replaced it? More… Discuss

THIS DAY IN THE YESTERYEAR: Antoine Lavoisier Tried, Convicted, and Guillotined (1794)


Antoine Lavoisier Tried, Convicted, and Guillotined (1794)

Known today as the “father of modern chemistry,” Lavoisier was among the first to use quantitative methods in chemical investigations. He stated the first version of the Law of Conservation of Mass, named oxygen and discovered its role in combustion, and helped to construct the metric system. Lavoisier also worked to improve economic and social conditions in France. He was beheaded during the Reign of Terror because, as a member of the farmers general, one of his duties was to do what?

THIS DAY IN THE YESTERYEAR: DMITRI MENDELEEV PRESENTS FIRST PERIODIC TABLE (1869)


Dmitri Mendeleev Presents First Periodic Table (1869)

The periodic table is a tabular display of all known chemical elements arranged according to the periodic law discovered by Russian chemist Dmitri Mendeleev. The elements are arranged in columns and rows according to increasing atomic number, which is defined as the number of protons in the nucleus of an atom. The table summarizes the major properties of the elements and enables predictions to be made about their behavior. How many elements currently appear on the periodic table? More…

Statue (my poetic thoughs)


Statue

When you notice a statue cry,
stop what we’re doing, look, listen, and try
To understand why does the statue cry.

Why,

Why does the marble cry, how does petrified wood,
No chemistry in it, all science put aside,
No theories…  Just  ask yourself:
What, what made the statue cry?

Today’s Birthday: Jöns Jakob Berzelius (1779)


Jöns Jakob Berzelius (1779)

Regarded as one of the founders of modern chemistry, Berzelius was a Swedish professor who achieved an immensely important series of innovations and discoveries. He developed chemistry’s modern system of symbols and formulas, prepared a remarkably precise table of atomic weights, analyzed numerous chemical compounds, and discovered the elements selenium, thorium, and cerium. He also introduced basic laboratory equipment that remains in use today. What common scientific terms did Berzelius coin? More… Discuss

Sodium intake in the right amount is indispensable for life. When too much of it accumulates in the human body, excess water retention and  circulatory problems will appear. Among those, high blood pressure can lead to heat attack. It is important to realise that while sodium Chloride (table salt) is the main contributor, many ingredients in foods (including sweets) contain large quantities of sodium compounds. In addition, many medicines are made with sodium compounds, including Alka Seltzer (sodium bicarbonate)

The word is MODERATION!

From http://en.wikipedia.org/wiki/Linus_Pauling

Linus Carl Pauling (February 28, 1901 – August 19, 1994)[1] was an American chemist, biochemist, peace activist, author and educator. He was one of the most influential chemists in history and ranks among the most important scientists of the 20th century.[2][3] Pauling was among the first scientists to work in the fields of quantum chemistry and molecular biology.

Pauling is one of only four individuals to have won more than one Nobel Prize.[4] He is one of only two people awarded Nobel Prizes in different fields (the Chemistry and Peace prizes), the other being Marie Curie (the Chemistry and Physics prizes), and the only person awarded two unshared prizes…

“How to live longer and feel better” by Linus Pauling, is a book to lean from, just like al his publications, manuals and abstracts.

 Vitamin C or L-ascorbic acid or L-ascorbate is an essential nutrient for humans and certain other animal species. In living organisms ascorbate acts as an antioxidant by protecting the body against oxidative stress.[1] It is also a cofactor in at least eight enzymatic reactions including several collagen synthesis reactions that cause the most severe symptoms of scurvy when they are dysfunctional.[2] In animals these reactions are especially important in wound-healing and in preventing bleeding from capillaries. (Source: http://en.wikipedia.org/wiki/Vitamin_C)

Vitamin C is found in fresh fruits and vegetables.

So: Eat your veggies and  fruits, Daily!

Luis Ernesto Miramontes Cárdenas (1925)

Miramontes was a Mexican chemist whose extensive scientific contributions include numerous publications and nearly 40 national and international patents in different areas, including organic chemistry, pharmaceutical chemistry, petrochemistry, atmospheric chemistry, and polluting agents. However, Miramontes is best remembered for his synthesis, in 1951, of norethindrone, a progestational hormone.
