James Chadwick: Ahead of His Time
July 15, 2020 James Chadwick: ahead of his time Gerhard Ecker University of Vienna, Faculty of Physics Boltzmanngasse 5, A-1090 Wien, Austria Abstract James Chadwick is known for his discovery of the neutron. Many of his earlier findings and ideas in the context of weak and strong nuclear forces are much less known. This biographical sketch attempts to highlight the achievements of a scientist who paved the way for contemporary subatomic physics. arXiv:2007.06926v1 [physics.hist-ph] 14 Jul 2020 1 Early years James Chadwick was born on Oct. 20, 1891 in Bollington, Cheshire in the northwest of England, as the eldest son of John Joseph Chadwick and his wife Anne Mary. His father was a cotton spinner while his mother worked as a domestic servant. In 1895 the parents left Bollington to seek a better life in Manchester. James was left behind in the care of his grandparents, a parallel with his famous predecessor Isaac Newton who also grew up with his grandmother. It might be an interesting topic for sociologists of science to find out whether there is a correlation between children educated by their grandmothers and future scientific geniuses. James attended Bollington Cross School. He was very attached to his grandmother, much less to his parents. Nevertheless, he joined his parents in Manchester around 1902 but found it difficult to adjust to the new environment. The family felt they could not afford to send James to Manchester Grammar School although he had been offered a scholarship. Instead, he attended the less prestigious Central Grammar School where the teaching was actually very good, as Chadwick later emphasised. -

In particular, it described how space also known as Einstein Year. In the century since Einstein’s becomes distorted near a massive object such as a star, so that light follows a curved path rather than annus mirabilis (see CATALYST Vol. 16, No. 1) there has travelling in a straight line (Figure 1). been a revolution in the study of physics. This article explores Its publication in wartime and the fact that it was the links between some of the architects of this revolution. written in German meant that few people read it. However, one person who did read it was the British astronomer Arthur Eddington. The story goes that it was Eddington who brought Einstein to the world’s attention — though Einstein might have disagreed. instein did not become instantly famous in Eddington was a conscientious objector.

DNA: the Timeline and Evidence of Discovery
1/19/2017 DNA: The Timeline and Evidence of Discovery Interactive Click and Learn (Ann Brokaw Rocky River High School) Introduction For almost a century, many scientists paved the way to the ultimate discovery of DNA and its double helix structure. Without the work of these pioneering scientists, Watson and Crick may never have made their ground-breaking double helix model, published in 1953. The knowledge of how genetic material is stored and copied in this molecule gave rise to a new way of looking at and manipulating biological processes, called molecular biology. The breakthrough changed the face of biology and our lives forever. Watch The Double Helix short film (approximately 15 minutes) – hyperlinked here. 1 1/19/2017 1865 The Garden Pea 1865 The Garden Pea In 1865, Gregor Mendel established the foundation of genetics by unraveling the basic principles of heredity, though his work would not be recognized as “revolutionary” until after his death. By studying the common garden pea plant, Mendel demonstrated the inheritance of “discrete units” and introduced the idea that the inheritance of these units from generation to generation follows particular patterns. These patterns are now referred to as the “Laws of Mendelian Inheritance.” 2 1/19/2017 1869 The Isolation of “Nuclein” 1869 Isolated Nuclein Friedrich Miescher, a Swiss researcher, noticed an unknown precipitate in his work with white blood cells. Upon isolating the material, he noted that it resisted protein-digesting enzymes. Why is it important that the material was not digested by the enzymes? Further work led him to the discovery that the substance contained carbon, hydrogen, nitrogen and large amounts of phosphorus with no sulfur. -
Frederick Griffith and Transformation
Balderdash Example Griffith’s Transformation Experiment Ever since Edward Jenner invented the first vaccine in 1796 scientists have been working to vaccinate the world against all known diseases. Frederick Griffith wanted to save the world from pneumonia, a disease that was killing off much of Europe during the 1920’s. He didn’t build the pneumonia vaccine, but he did accidentally discover one of the most important concepts in bacterial survivability: Griffith discovered the principle of bacterial transformation. (In other words, why bacteria can fight off antibiotics) Griffith’s Transformation Experiment In 1928, Frederick Griffith was working with mice and two strains of Streptococcus pneumoniae One strain was “rough” in appearance and non-virulent, meaning that it wasn’t strong enough to hurt it’s host One strain was “smooth” in appearance and virulent. It was deadly to anyone who contracted the strain. The smooth strain looked smooth because it lacked a special protein coat that was rough in appearance and acted as a beacon summoning the mice’s immune systems. When injected with the rough (non-virulent) strain, mice lived When injected with the smooth (virulent) strain, mice died. Both as expected. Griffith’s Transformation Experiment Next, Griffith boiled the deadly, smooth strand of bacteria to kill it. He then injected mice with the deadly but boiled strand. Once again, as expected, the mice still lived. Finally, he injected the mice with BOILED smooth strands and LIVING rough strands The smooth strands are normally deadly, but Griffith had boiled them so they were not dangerous anymore. The rough strands were never deadly even when they were alive. -

THINK ABOUT IT How do genes work? Lesson Overview To answer that question, the first thing you need to 12.1 Identifying the know is what genes are made of. Substance of Genes How would you go about figuring out what molecule or molecules go into making a gene? Griffith’s Experiments Bacterial Transformation Griffith isolated two different strains of the same bacterial The discovery of the chemical nature of the gene began in 1928 species. with British scientist Frederick Griffith, who was trying to figure Both strains grew very well in culture plates in Griffith’s lab, but out how certain types of bacteria produce pneumonia. only one of the strains caused pneumonia. The disease-causing bacteria (S strain) grew into smooth colonies on culture plates, whereas the harmless bacteria (R strain) produced colonies with rough edges. Griffith’s Experiments Griffith’s Experiments When Griffith injected mice with disease-causing bacteria, First, Griffith took a culture of the S strain, heated the cells the mice developed pneumonia and died. to kill them, and then injected the heat-killed bacteria into When he injected mice with harmless bacteria, the mice laboratory mice. stayed healthy. The mice survived, suggesting that the cause of pneumonia Perhaps the S-strain bacteria produced a toxin that made was not a toxin from these disease-causing bacteria. the mice sick? To find out, Griffith ran a series of experiments. Griffith’s Experiments Griffith’s Experiments In Griffith’s next experiment, he mixed the heat-killed, The lungs of these mice were filled with the disease-causing S-strain bacteria with live, harmless bacteria from the R bacteria. -

If the Bethe was born in Strasbourg, Alsace- mass of hydrogen nucleus can be written as 1, Lorraine (then part of Germany) on 2 July 1906. Bethe showed that each time four nuclei of His father was a University physiologist and his hydrogen fused together as helium, their sum was mother Jewish, the daughter of a Strasbourg not equal to 4. The helium nucleus weighs about professor of Medicine. Bethe moved to Kiel and 0.7% less, or just 3.993 units of weight. It is this Frankfurt from where he went to Munich to carry missing 0.7% that comes out as a burst of explosive out research in theoretical physics under Arnold energy.

Einstein's famous equation, E = mc2, Bethe received his doctorate in 1928, for the work provides a clue to the massive energy that reaches he did on electron diffraction.
