Ernest Rutherford#Arms

Ernest Rutherford was born on 30 August 1871 in Brightwater, a town near Nelson, New Zealand. He was the fourth of twelve children of James Rutherford, an immigrant farmer and mechanic from Perth, Scotland, and his wife Martha Thompson, a schoolteacher from Hornchurch, England.{{cite encyclopedia|author=A.H.

When Rutherford was five he moved to Foxhill, New Zealand, and attended Foxhill School. At age 11 in 1883, the Rutherford family moved to Havelock, a town in the Marlborough Sounds. The move was made to be closer to the flax mill Rutherford's father developed. Ernest studied at Havelock School.{{Cite news |date=7 October 1886 |title=Local and General News. |volume=22 |page=2 |work=Marlborough Express |issue=186 |url=https://paperspast.natlib.govt.nz/newspapers/MEX18861007.2.8? |access-date=October 1, 2023 |via=Papers Past |archive-date=8 August 2023 |archive-url=https://web.archive.org/web/20230808010845/https://paperspast.natlib.govt.nz/newspapers/MEX18861007.2.8 |url-status=live }}

In 1889, after his second attempt, he won a scholarship to study at Canterbury College, University of New Zealand, between 1890 and 1894. He participated in its debating society and the Science Society. At Canterbury, he was awarded a complex BA in Latin, English, and Maths in 1892, a MA in Mathematics and Physical Science in 1893, and a BSc in Chemistry and Geology in 1894.{{cite web |title=Ernest Rutherford Biographical |url=https://www.nobelprize.org/prizes/chemistry/1908/rutherford/biographical/ |archive-url=https://web.archive.org/web/20230603075847/https://www.nobelprize.org/prizes/chemistry/1908/rutherford/biographical/ |archive-date=3 June 2023 |url-status=live |website=The Nobel Prize |publisher=Nobel Prize Outreach AB |access-date=5 October 2023}}{{cite web |title=Famous Canterbury graduate Ernest Rutherford turns 150 |url=https://www.canterbury.ac.nz/news/2021/famous-canterbury-graduate-ernest-rutherford-turns-150.html |website=The University of Canterbury |access-date=3 July 2023 |language=en-nz |date=27 August 2021 |archive-date=3 July 2023 |archive-url=https://web.archive.org/web/20230703222040/https://www.canterbury.ac.nz/news/2021/famous-canterbury-graduate-ernest-rutherford-turns-150.html |url-status=live }}

When Rutherford began his studies at Cambridge, he was among the first 'aliens' (those without a Cambridge degree) allowed to do research at the university, and was additionally honoured to study under J. J. Thomson.

With Thomson's encouragement, Rutherford detected radio waves at {{convert|0.5|mi|m}}, and briefly held the world record for the distance over which electromagnetic waves could be detected, although when he presented his results at the British Association meeting in 1896, he discovered he had been outdone by Guglielmo Marconi, whose radio waves had sent a message across nearly {{convert|10|mi|km}}.{{cite news |last1=Holmes |first1=Jonathan |title=Marconi's first radio broadcast made 125 years ago |url=https://www.bbc.com/news/uk-england-somerset-61327062 |access-date=16 June 2023 |work=BBC News |date=13 May 2022 |archive-date=5 June 2023 |archive-url=https://web.archive.org/web/20230605224315/https://www.bbc.com/news/uk-england-somerset-61327062 |url-status=live }}

Again under Thomson's leadership, Rutherford worked on the conductive effects of X-rays on gases, which led to the discovery of the electron, the results first presented by Thomson in 1897.{{cite book |last1=Buchwald |first1=Jed Z. |last2=Warwick |first2=Andrew |title=Histories of the electron: the birth of microphysics |date=30 January 2004 |publisher=MIT Press |location=Cambridge, Mass. |isbn=0262524244 |pages=21–30 |url=https://books.google.com/books?id=1yqqhlIdCOoC&pg=PA21 |access-date=27 June 2023 |archive-date=29 August 2023 |archive-url=https://web.archive.org/web/20230829163251/https://books.google.com/books?id=1yqqhlIdCOoC&pg=PA21 |url-status=live }} Hearing of Henri Becquerel's experience with uranium, Rutherford started to explore its radioactivity, discovering two types that differed from X-rays in their penetrating power. Continuing his research in Canada, in 1899 he coined the terms "alpha ray" and "beta ray" to describe these two distinct types of radiation.{{Cite journal|last=Trenn|first=Thaddeus J.|date=1976|title=Rutherford on the Alpha-Beta-Gamma Classification of Radioactive Rays|journal=Isis|volume=67|issue=1|pages=61–75|jstor=231134|doi=10.1086/351545|s2cid=145281124}}

In 1898, Rutherford was accepted to the chair of Macdonald Professor of physics position at McGill University in Montreal, Canada, on Thomson's recommendation.{{cite book| first=Robin| last=McKown| authorlink=Robin McKown|title=Giant of the Atom, Ernest Rutherford| url=https://archive.org/details/giantofatomernes00mcko|url-access=registration|year=1962|publisher=Julian Messner Inc, New York|page=[https://archive.org/details/giantofatomernes00mcko/page/57 57]}} From 1900 to 1903, he was joined at McGill by the young chemist Frederick Soddy (Nobel Prize in Chemistry, 1921) for whom he set the problem of identifying the noble gas emitted by the radioactive element thorium, a substance which was itself radioactive and would coat other substances. Once he had eliminated all the normal chemical reactions, Soddy suggested that it must be one of the inert gases, which they named thoron. This substance was later found to be ²²⁰Rn, an isotope of radon.{{Cite arXiv|last=Kragh|first=Helge|date=5 February 2012|title=Rutherford, Radioactivity, and the Atomic Nucleus|eprint=1202.0954|class=physics.hist-ph}} They also found another substance they called Thorium X, later identified as ²²⁴Rn, and continued to find traces of helium. They also worked with samples of "Uranium X" (protactinium), from William Crookes, and radium, from Marie Curie. Rutherford further investigated thoron in conjunction with R.B. Owens and found that a sample of radioactive material of any size invariably took the same amount of time for half the sample to decay (in this case, 11{{frac|1|2}} minutes), a phenomenon for which he coined the term "half-life". Rutherford and Soddy published their paper "Law of Radioactive Change" to account for all their experiments. Until then, atoms were assumed to be the indestructible basis of all matter; and although Curie had suggested that radioactivity was an atomic phenomenon, the idea of the atoms of radioactive substances breaking up was a radically new idea. Rutherford and Soddy demonstrated that radioactivity involved the spontaneous disintegration of atoms into other, as yet, unidentified matter.

In 1903, Rutherford considered a type of radiation, discovered (but not named) by French chemist Paul Villard in 1900, as an emission from radium, and realised that this observation must represent something different from his own alpha and beta rays, due to its very much greater penetrating power. Rutherford therefore gave this third type of radiation the name of gamma ray. All three of Rutherford's terms are in standard use today – other types of radioactive decay have since been discovered, but Rutherford's three types are among the most common. In 1904, Rutherford suggested that radioactivity provides a source of energy sufficient to explain the existence of the Sun for the many millions of years required for the slow biological evolution on Earth proposed by biologists such as Charles Darwin. The physicist Lord Kelvin had argued earlier for a much younger Earth, based on the insufficiency of known energy sources, but Rutherford pointed out, at a lecture attended by Kelvin, that radioactivity could solve this problem.{{cite journal |author1=England, P. |author2=Molnar, P. |author3=Righter, F. | title=John Perry's neglected critique of Kelvin's age for the Earth: A missed opportunity in geodynamics |journal=GSA Today |date=January 2007 |volume=17 |issue=1 |pages=4–9 |doi=10.1130/GSAT01701A.1 |bibcode=2007GSAT...17R...4E |doi-access= free}} Later that year, he was elected as a member to the American Philosophical Society,{{Cite web|title=APS Member History|url=https://search.amphilsoc.org/memhist/search?creator=&title=&subject=&subdiv=&mem=&year=1904&year-max=&dead=&keyword=&smode=advanced|access-date=28 June 2021|website=search.amphilsoc.org|archive-date=28 June 2021|archive-url=https://web.archive.org/web/20210628190035/https://search.amphilsoc.org/memhist/search?creator=&title=&subject=&subdiv=&mem=&year=1904&year-max=&dead=&keyword=&smode=advanced|url-status=live}} and in 1907 he returned to Britain to take the chair of physics at the Victoria University of Manchester.{{cite web |title=Ernest Rutherford: Heritage Heroes at The University of Manchester |url=https://www.manchester.ac.uk/discover/history-heritage/history/heroes/ernest-rutherford/ |website=The University of Manchester |access-date=27 June 2023 |language=en |archive-date=27 June 2023 |archive-url=https://web.archive.org/web/20230627004723/https://www.manchester.ac.uk/discover/history-heritage/history/heroes/ernest-rutherford/ |url-status=live }}

In Manchester, Rutherford continued his work with alpha radiation. In conjunction with Hans Geiger, he developed zinc sulfide scintillation screens and ionisation chambers to count alpha particles. By dividing the total charge accumulated on the screen by the number counted, Rutherford determined that the charge on the alpha particle was two.{{Cite journal |date=1908-08-27 |title=The charge and nature of the α-particle |journal=Proceedings of the Royal Society of London.

Reflecting on these results in one of his last lectures, Rutherford was quoted as saying: "It was quite the most incredible event that has ever happened to me in my life. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you."The Development of the Theory of Atomic Structure (Rutherford 1936).

In 1912, Rutherford was joined by Niels Bohr (who postulated that electrons moved in specific orbits about the compact nucleus). Bohr adapted Rutherford's nuclear structure to be consistent with Max Planck's quantum hypothesis. The resulting Rutherford–Bohr model was the basis for quantum mechanical atomic physics of Heisenberg which remains valid today.

During World War I, Rutherford worked on a top-secret project to solve the practical problems of submarine detection. Both Rutherford and Paul Langevin suggested the use of piezoelectricity, and Rutherford successfully developed a device which measured its output. The use of piezoelectricity then became essential to the development of ultrasound as it is known today. The claim that Rutherford developed sonar, however, is a misconception, as subaquatic detection technologies utilise Langevin's transducer.{{cite journal |last1=Katzir |first1=Shaul |title=Who knew piezoelectricity?

Together with H.G. Moseley, Rutherford developed the atomic numbering system in 1913. Rutherford and Moseley's experiments used cathode rays to bombard various elements with streams of electrons and observed that each element responded in a consistent and distinct manner. Their research was the first to assert that each element could be defined by the properties of its inner structures – an observation that later led to the discovery of the atomic nucleus. This research led Rutherford to theorize that the hydrogen atom (at the time the least massive entity known to bear a positive charge) was a sort of "positive electron" – a component of every atomic element.{{cite journal |last1=Rutherford |first1=Ernest |title=The structure of the atom |journal=Philosophical Magazine |date=1914 |volume=27 |pages=488–498 |url=http://www.ub.edu/hcub/hfq/sites/default/files/ruth1914%285%29.pdf |access-date=13 June 2023 |archive-date=13 June 2023 |archive-url=https://web.archive.org/web/20230613022543/http://www.ub.edu/hcub/hfq/sites/default/files/ruth1914(5).pdf |url-status=live }}{{cite book |last1=Whittaker |first1=Edmund |title=A History of the Theories of Aether and Electricity |date=1989 |volume=2 |publisher=Courier Dover Publications |isbn=0-486-26126-3 |page=87}}

It was not until 1919 that Rutherford expanded upon his theory of the "positive electron" with a series of experiments beginning shortly before the end of his time at Manchester. He found that nitrogen, and other light elements, ejected a proton, which he called a "hydrogen atom", when hit with α (alpha) particles. In particular, he showed that particles ejected by alpha particles colliding with hydrogen have unit charge and 1/4 the momentum of alpha particles.{{cite journal |last1=Rutherford |first1=Ernest |title=LII.

Rutherford returned to the Cavendish Laboratory in 1919, succeeding J. J.

In 1919–1920, Rutherford continued his research on the "hydrogen atom" to confirm that alpha particles break down nitrogen nuclei and to affirm the nature of the products. This result showed Rutherford that hydrogen nuclei were a part of nitrogen nuclei (and by inference, probably other nuclei as well). Such a construction had been suspected for many years, on the basis of atomic weights that were integral multiples of that of hydrogen; see Prout's hypothesis. Hydrogen was known to be the lightest element, and its nuclei presumably the lightest nuclei. Now, because of all these considerations, Rutherford decided that a hydrogen nucleus was possibly a fundamental building block of all nuclei, and also possibly a new fundamental particle as well, since nothing was known to be lighter than that nucleus. Thus, confirming and extending the work of Wilhelm Wien, who in 1898 discovered the proton in streams of ionized gas,{{Cite journal|doi = 10.1002/andp.18943180404|title = Über positive Elektronen und die Existenz hoher Atomgewichte|journal = Annalen der Physik|volume = 318|issue = 4|pages = 669–677|year = 1904|last1 = Wien|first1 = W.|bibcode = 1904AnP...318..669W|url = https://zenodo.org/record/2190505|access-date = 5 September 2020|archive-date = 13 July 2020|archive-url = https://web.archive.org/web/20200713133516/https://zenodo.org/record/2190505|url-status = live}} in 1920 Rutherford postulated the hydrogen nucleus to be a new particle, which he dubbed the proton.{{cite journal |author=Orme Masson |date=1921 |title=The Constitution of Atoms |journal=The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science |volume=41 |issue=242 |pages=281–285 |doi=10.1080/14786442108636219 |url=https://archive.org/details/londonedinburg6411921lond/page/280/mode/2up }}
Footnote by Ernest Rutherford: 'At the time of writing this paper in Australia, Professor Orme Masson was not aware that the name "proton" had already been suggested as a suitable name for the unit of mass nearly 1, in terms of oxygen 16, that appears to enter into the nuclear structure of atoms. The question of a suitable name for this unit was discussed at an informal meeting of a number of members of Section A of the British Association at Cardiff this year. The name "baron" suggested by Professor Masson was mentioned, but was considered unsuitable on account of the existing variety of meanings. Finally the name "proton" met with general approval, particularly as it suggests the original term "protyle " given by Prout in his well-known hypothesis that all atoms are built up of hydrogen. The need of a special name for the nuclear unit of mass 1 was drawn attention to by Sir Oliver Lodge at the Sectional meeting, and the writer then suggested the name "proton."'

In 1921, while working with Niels Bohr, Rutherford theorized about the existence of neutrons, (which he had christened in his 1920 Bakerian Lecture), which could somehow compensate for the repelling effect of the positive charges of protons by causing an attractive nuclear force and thus keep the nuclei from flying apart, due to the repulsion between protons. The only alternative to neutrons was the existence of "nuclear electrons", which would counteract some of the proton charges in the nucleus, since by then it was known that nuclei had about twice the mass that could be accounted for if they were simply assembled from hydrogen nuclei (protons). But how these nuclear electrons could be trapped in the nucleus, was a mystery.

In 1932, Rutherford's theory of neutrons was proved by his associate James Chadwick, who recognised neutrons immediately when they were produced by other scientists and later himself, in bombarding beryllium with alpha particles. In 1935, Chadwick was awarded the Nobel Prize in Physics for this discovery.{{cite web |title=James Chadwick – Facts |url=https://www.nobelprize.org/prizes/physics/1935/chadwick/facts/ |website=The Nobel Prize |publisher=Nobel Prize Outreach AB |access-date=16 June 2023 |archive-date=4 October 2019 |archive-url=https://web.archive.org/web/20191004015954/https://www.nobelprize.org/prizes/physics/1935/chadwick/facts/ |url-status=live }}

In Rutherford's four-part article on the "Collision of α-particles with light atoms" he reported two additional fundamental and far reaching discoveries.{{rp|237}} First, he showed that at high angles the scattering of alpha particles from hydrogen differed from the theoretical results he himself published in 1911. These were the first results to probe the interactions that hold a nucleus together. Second, he showed that α-particles colliding with nitrogen nuclei would react rather than simply bounce off. One product of the reaction was the proton; the other product was shown by Patrick Blackett, Rutherford's colleague and former student, to be oxygen:

:¹⁴N + α → ¹⁷O + p.

Rutherford therefore recognised "that the nucleus may increase rather than diminish in mass as the result of collisions in which the proton is expelled".{{cite journal |last1=Rutherford |first1=Sir Ernest |title=Studies of Atomic Nuclei |url=https://archive.org/details/RoyalInstitutionLibraryOfScience-PhysicalScienceVol9 |date=27 March 1925 |journal=Science |volume=62 |issue=1601 |pages=73–76 |publisher=The Royal Institution Library of Sciences |doi=10.1126/science.62.1601.209 |pmid=17748045 |bibcode=1925Sci....62..209R |access-date=2 October 2023}}

Blackett was awarded the Nobel prize in 1948 for his work in perfecting the high-speed cloud chamber apparatus used to make that discovery and many others.{{cite journal |title=Nobel Prize for Physics : Prof. P.

Rutherford received significant recognition in his home country of New Zealand. In 1901, he earned a DSc from the University of New Zealand.

Rutherford's hobbies included golf and motoring.

For some time before his death, Rutherford had a small hernia, which he neglected to have repaired, and it eventually became strangulated, rendering him violently ill. He had an emergency operation in London, but died in Cambridge four days later, on 19 October 1937, at age 66, of what physicians termed "intestinal paralysis".{{cite book|title=The Complete Peerage, Volume XIII – Peerage Creations, 1901–1938|year=1949|publisher=St Catherine's Press|page=495}} After cremation at Golders Green Crematorium, he was given the high honour of burial in Westminster Abbey, near Isaac Newton, Charles Darwin, and other illustrious British scientists.{{Cite book|last=Heilbron|first=J.

At the opening session of the 1938 Indian Science Congress, which Rutherford had been expected to preside over before his death, astrophysicist James Jeans spoke in his place and deemed him "one of the greatest scientists of all time", saying:

{{blockquote|In his flair for the right line of approach to a problem, as well as in the simple directness of his methods of attack, [Rutherford] often reminds us of Faraday, but he had two great advantages which Faraday did not possess, first, exuberant bodily health and energy, and second, the opportunity and capacity to direct a band of enthusiastic co-workers. Great though Faraday's output of work was, it seems to me that to match Rutherford's work in quantity as well as in quality, we must go back to Newton. In some respects he was more fortunate than Newton. Rutherford was ever the happy warrior – happy in his work, happy in its outcome, and happy in its human contacts.{{cite news |title=Viceroy Opens The Congress – Sir James Jeans's Address|work=The Times |location=Calcutta |date=3 January 1938 }}}}

Rutherford is known as "the father of nuclear physics" because his research, and work done under him as laboratory director, established the nuclear structure of the atom and the essential nature of radioactive decay as a nuclear process.{{cite web |title=Ernest Rutherford |url=https://ehs.msu.edu/lab-clinic/rad/hist-figures/rutherford.html |website=Environmental Health and Safety Office of Research Regulatory Support |publisher=Michigan State University |access-date=23 June 2023 |archive-date=22 June 2023 |archive-url=https://web.archive.org/web/20230622163634/https://ehs.msu.edu/lab-clinic/rad/hist-figures/rutherford.html |url-status=live }}{{cite web |title=Ernest Rutherford: father of nuclear science |url=https://media.newzealand.com/en/story-ideas/ernest-rutherford-father-of-nuclear-science/ |website=New Zealand Media Resources |archive-url=https://web.archive.org/web/20210612184534/https://media.newzealand.com/en/story-ideas/ernest-rutherford-father-of-nuclear-science/ |archive-date=12 June 2021 |language=en |url-status=dead}}{{cite web |title=Know the scientist: Ernest Rutherford |url=https://www.thehindu.com/children/know-the-scientist-ernest-rutherford/article34837002.ece |website=The Hindu |access-date=23 June 2023 |language=en-IN |date=17 June 2021 |archive-date=23 June 2023 |archive-url=https://web.archive.org/web/20230623183847/https://www.thehindu.com/children/know-the-scientist-ernest-rutherford/article34837002.ece |url-status=live }} Patrick Blackett, a research fellow working under Rutherford, using natural alpha particles, demonstrated induced nuclear transmutation.

Rutherford died too early to see Leó Szilárd's idea of controlled nuclear chain reactions come into being. However, a speech of Rutherford's about his artificially-induced transmutation in lithium, printed in the 12 September 1933 issue of The Times, was reported by Szilárd to have been his inspiration for thinking of the possibility of a controlled energy-producing nuclear chain reaction.{{cite web |title=September 12, 1933 – Leó Szilárd conceives the idea of the nuclear chain reaction |url=https://rinconeducativo.org/en/anniversaries/september-12-1933-leo-szilard-conceives-the-idea-of-the-nuclear-chain-reaction/#:~:text=On%20September%2012%2C%201933%2C%20in%20London%2C%20Szil%C3%A1rd%20read,transformation%20of%20atoms%20was%20talking%20about%20%22silly%20alcohol%22. |website=Rincón educativo |access-date=27 June 2023 |language=Spanish, English |archive-date=27 June 2023 |archive-url=https://web.archive.org/web/20230627010731/https://rinconeducativo.org/en/anniversaries/september-12-1933-leo-szilard-conceives-the-idea-of-the-nuclear-chain-reaction/#:~:text=On%20September%2012%2C%201933%2C%20in%20London%2C%20Szil%C3%A1rd%20read,transformation%20of%20atoms%20was%20talking%20about%20%22silly%20alcohol%22. |url-status=live }}

Rutherford's speech touched on the 1932 work of his students John Cockcroft and Ernest Walton in "splitting" lithium into alpha particles by bombardment with protons from a particle accelerator they had constructed. Rutherford realised that the energy released from the split lithium atoms was enormous, but he also realised that the energy needed for the accelerator, and its essential inefficiency in splitting atoms in this fashion, made the project an impossibility as a practical source of energy (accelerator-induced fission of light elements remains too inefficient to be used in this way, even today). Rutherford's speech in part, read:

{{blockquote|We might in these processes obtain very much more energy than the proton supplied, but on the average we could not expect to obtain energy in this way. It was a very poor and inefficient way of producing energy, and anyone who looked for a source of power in the transformation of the atoms was talking moonshine. But the subject was scientifically interesting because it gave insight into the atoms.{{Cite news|work=The Times |title=The British association – breaking down the atom |date=12 September 1933}}{{cite book|last=Rhodes |first=Richard |title=The Making of the Atomic Bomb |location=New York |publisher=Simon and Schuster |year=1986 |page=27 |author-link=Richard Rhodes |title-link=The Making of the Atomic Bomb |isbn=0-671-44133-7}}}}
