Talk with Linus Pauling

Linus Pauling was a Nobel laureate in Chemistry and Peace, renowned for his pioneering work in quantum chemistry and molecular biology.


Who is Linus Pauling?

Linus Pauling was an American chemist, biochemist, peace activist, author, and educator. He is one of only four individuals to have won more than one Nobel Prize. He is known for his work in the field of quantum chemistry and molecular biology. In 1954, he won the Nobel Prize in Chemistry for his research into the nature of the chemical bond and its application to the elucidation of the structure of complex substances. In 1962, he received the Nobel Peace Prize for his activism against nuclear weapons testing. He was also one of the first scientists to propose that DNA was a triple helix, though later evidence proved the correct structure was a double helix.

What part did Linus Pauling play in the discovery of DNA structure?

Linus Pauling did not directly contribute to the discovery of the DNA molecule's structure; that achievement is accredited to Francis Crick, James Watson, Maurice Wilkins, and Rosalind Franklin. However, Pauling's work in molecular biology and protein structure profoundly influenced the field.

In the early 1950s, Pauling proposed a triple helix model for DNA, based on his successful prediction of the alpha helix structure for proteins. This model was incorrect, mainly due to the lack of high-quality X-ray crystallography data, which Watson and Crick had access to, and his assumption about the size and location of the phosphate groups. Although this was a setback for Pauling, it indirectly stimulated further research.

Watson and Crick, aware of Pauling's intellect and past achievements in molecular structure determination (like the alpha helix structure in proteins), felt a sense of urgency to solve the structure of DNA before Pauling could. So, his incorrect model arguably accelerated the discovery process. Pauling's pioneering efforts in molecular biology and his methods of working out molecular structures set the stage for numerous scientific breakthroughs, including the eventual accurate determination of the DNA double helix structure.

What led Linus Pauling towards peace activism?

Linus Pauling became a peace activist largely due to the devastation caused by nuclear weapons, particularly after the bombings of Hiroshima and Nagasaki in Japan during World War II. He was deeply concerned about the potential for human extinction from nuclear warfare.

Himself a scientist who made significant contributions to the understanding of molecular structures, he also understood the dangerous potential of nuclear technology if used in warfare. This formed a dichotomy in his life, as he loved scientific progress but deplored the horrifying uses that some of these advancements could have.

Pauling also believed in the social responsibility of scientists to use their knowledge for the betterment of humanity. This belief was nourished by his understanding of Quaker philosophies, which his wife, Ava Helen, introduced to him. Ava was an important influence in his life and brought him closer to social and political issues related to peace, equality, and justice.

In 1957, he began a petition signed by thousands of scientists worldwide to stop nuclear weapons testing, eventually leading to the Partial Test Ban Treaty. The endeavor earned him the Nobel Peace Prize in 1962, making him one of only four individuals to win a Nobel Prize in two different fields (he won the Nobel Prize in Chemistry in 1954). Pauling dedicated his later years to promoting peace, and was known as much for his peace activism as for his scientific work.

Did Linus Pauling have any notable collaborations with other scientists?

Yes, Linus Pauling was associated with a number of notable collaborations throughout his career.

  1. Robert Corey: Pauling's long-time collaborator was his Caltech colleague, Robert B. Corey. They spent many years studying the molecular structures of proteins, leading to their famous Pauling-Corey Rules which established guidelines for protein structure.

  2. E. Bright Wilson: Pauling collaborated with E. Bright Wilson on the book "Introduction to Quantum Mechanics," which became one of the standard textbooks in the field.

  3. Carl Niemann: Together, they published a paper on protein structure in Science in 1939, which served as a foundation of Pauling's further work in the field.

  4. Charles Coryell: Coryell was a Ph.D. student of Pauling's, and together, they discovered the element promethium.

Pauling's research style encouraged cross-disciplinary effort, bringing together researchers from varied backgrounds. This led to an increase in scientific innovation, which is still practiced in modern scientific research today.

Describe Linus Pauling's work on orthomolecular medicine.

Linus Pauling's work in orthomolecular medicine defines it as the practice of preventing and treating disease by providing the body with optimal amounts of substances which are natural to the body. He believed that diseases could be treated by adjusting the concentrations of molecules that are normally present in the body, hence the term "ortho" which is Greek for "correct".

One of Pauling's primary areas of focus within orthomolecular medicine was vitamin C. He strongly advocated for high doses of vitamin C as a preventative and curative measure against many diseases. Pauling believed that the recommended daily allowances of vitamin C were inadequate and that higher quantities were beneficial for overall health, particularly in preventing colds.

He also extended his ideas to include other vitamins, minerals, and nutrients, arguing that deficiencies or imbalances of these substances could lead to diseases. His work and ideas, although controversial and still subject to much debate, have significantly influenced the fields of nutrition and health science. It has led to a broader acceptance of the idea that nutritional supplementation can enhance health and complement traditional medical treatments.

Nevertheless, it's worth mentioning that much of his work in orthomolecular medicine has been contested by the mainstream medical community, primarily because several large-scale studies did not validate his claims regarding the significant health benefits of extremely high doses of vitamin C.

What are Linus Pauling's main contributions to chemistry?

Linus Pauling made many significant contributions to chemistry, but he is perhaps best known for three major works:

  1. Quantum Mechanics and Chemical Bond Formation: Pauling applied quantum mechanics to explain the nature and properties of the chemical bond, particularly covalent bonding. His book, 'The Nature of the Chemical Bond,' is considered to be one of the most influential books in the history of chemistry. It provided a new theoretical framework to understand the structure and properties of molecules.

  2. Formulation of Electronegativity Concept: Pauling proposed the concept of electronegativity, defining it as the power of an atom in a molecule to attract electrons to itself. He developed the Pauling scale, a numerical scale that is used to compare the electronegativities of different atoms.

  3. Protein Structure: Pauling, along with Robert Corey, proposed models for the secondary structure of proteins. They introduced the Alpha Helix and Beta Sheet structure, which form the basis of the structure of many proteins. These discoveries revolutionized the field of protein biochemistry.

It's worth noting that Pauling's exceptional contributions to chemistry and peace activism led him to be awarded two individual Nobel Prizes: The Nobel Prize in Chemistry in 1954 and the Nobel Peace Prize in 1962.

What did Linus Pauling do?

Linus Pauling, an American theoretical physical chemist, made a significant contribution to the scientific world. He is widely recognized for his work in molecular biology, quantum chemistry, and involvement in political activism.

Probably his best-known work is his discovery on the nature of the chemical bond, which allowed him to establish the field of molecular biology. His work on the nature and properties of molecules earned him the Nobel Prize in Chemistry in 1954.

In 1962, he was awarded the Nobel Peace Prize for his peace activism, primarily against nuclear weapons testing, making him the only person to win two unshared Nobel Prizes.

Pauling also developed the concept of orthomolecular medicine, which suggests that certain diseases can be prevented or treated with optimal amounts of vitamins and minerals, although this theory is controversial and not broadly accepted in the mainstream medical community. His landmark work included studies on sickle cell anemia, where he was first to propose that it was a molecular disease.

How much vitamin C did Linus Pauling eat a day?

Linus Pauling is well-known for his advocacy of high-dose vitamin C. He personally consumed 18,000 milligrams (18 grams) of vitamin C per day. This is significantly higher than the amount commonly recommended for maintaining general health, which is usually between 75mg and 90mg per day.

Did Linus Pauling win the Nobel Prize?

Yes, Linus Pauling is one of the few individuals to have won two separate Nobel Prizes. He was awarded the Nobel Prize in Chemistry in 1954 for his research into the nature of the chemical bond and its application to the elucidation of the structure of complex substances.

Later, in 1962, he was awarded the Nobel Peace Prize for his efforts in campaigning against nuclear weapons testing. This makes him the only person to have been awarded two unshared Nobel Prizes.

Did Linus Pauling die from AIDS?

No, Linus Pauling did not die from AIDS. He passed away on August 19, 1994, from prostate cancer. Although he was known for promoting vitamin C's health benefits, particularly in fighting the common cold and cancer, it's important to clarify that these claims aren't universally accepted by the medical community.
