Astrophysicist and professor, Dame Jocelyn Bell Burnell reflects on how she helped change astronomy forever.In this episode, learn more about how a peculiar signal from space led Jocelyn to a groundbreaking discovery. She discusses her aerospace journey, building a radio telescope, discovering pulsars, and the 1974 Nobel Prize controversy. This one is going to be cool!Key Takeaways:At the time, women were not often permitted to study science fields in school. Her parents protested this rule and Jocelyn became top of her class in Physics.While attending Cambridge, Jocelyn helped build their radio telescope alongside Astronomers Martin Ryle and Antony Hewish.Originally the telescope was built to study Quasars, which are distant galaxies whose incredibly bright cores are powered by supermassive black holes. While observing and researching the telescope, Jocelyn found a strange "pulse" that occurred at regular intervals. Labeled LGM-1 or Little Green Men 1, it was the first recording of a pulsar.Since pulsars were discovered, over 3,000 have been found today.In 1974, Martin Ryle and Antony Hewish were awarded the Nobel Prize for the discovery of pulsars. Because Martin and Antony were the telescopes' leaders, Jocelyn, a student at the time, was left out. She has since been awarded several prestigious accolades.Jocelyn encourages audiences to double-check anomalies as they never know which scientific discoveries could be found.Resources:Jocelyn's Bio (Wikipedia) What are pulsars?

Los púlsares son estrellas de neutrones que emiten radiaciones periódicas, y una demostración de que la periodicidad también no es una propiedad exclusiva de lo artificial. Los científicos Jocelyn Bell y Antony Hewish descubrieron las primeras señales de un púlsar en 1967 y su descubrimiento valió el Premio Nobel de Física 1974, aunque la academia sueca obvió a Bell por ser mujer. Todo esto y mucho más en esta entrevista desclasificada del episodio 1x08 de Toma la pastilla roja, con la periodista científica América Valenzuela.

Ready for a party in your ears from those wacky Nerds again? This week we are celebrating, scratching our chins in suspicion, and looking at upcoming events that we can use to make money. But first, grab a cup of Earl Grey, hot, get a comfy seat and get ready because we have a party. It’s here, that marvellous time of year when we find out who has won a noble prize! It’s awesome, kind of like a Nerds holiday celebrating knowledge and learning, yay! For those wondering Buck is bouncing around the office with excitement. Speaking of which, his topic this week is the Nobel prize winners in Chemistry, and it is for the Lithium Ion battery. A long time coming we know, but still, it is definitely worthy. Buck is still reading the lists and articles about this, and the Professor is enjoying this to.Next up we have DJ telling us about the latest with him doing little, erm, um, oh, sorry. Apparently it is about the new Dolittle movie, not him being lazy. Now there are some interesting points in this section so make sure you listen carefully. We won’t give away all the details here, no, listen in and see what is happening. We can tell you there is a name change, and no, it isn’t DJ being rebranded to some funny name such as Purveyance Slave Droid. Mainly because he still hasn’t learned how to make the perfect cup of Earl Grey.Next we hear how someone has had an epically lucky coincidence when naming their crowd funding campaign. We are told it is completely unintentional though. Although Buck thinks that this is the next generation of Citizen Con, sorry, Star Con, no, what is it, star rippoff? Oh you know what we mean. Anyway, this bloke was trying to raise capital for a game he was developing and listen in to hear the rest of this fantastic story.As usual we have the shout outs, with special mention to Christina Koch and Jessica Meir, the first all female spacewalk crew. Then we have the usual remembrances, birthdays and special events. We are going to be appearing at Supanova Brisbane so stop by and say hello, we will be happy to see you, also we have a special announcement this next week. Until then, take care of yourselves, look out for each other and stay hydrated.EPISODE NOTES:Nobel Prize in Chemistry 2019 winners - https://www.downtoearth.org.in/news/science-technology/chemistry-nobel-for-development-of-lithium-ion-batteries-67159Dolittle movie update - https://deadline.com/video/universal-dolittle-robert-downey-jr-trailer/Day of Dragons confusion - https://twitter.com/icotom/status/1182291839027761152?s=20Games currently playingDJ– MK 11 - https://www.playstation.com/en-us/games/mortal-kombat-11-ps4/Rating – 4/5Buck– World of Warships - https://worldofwarships.com/Rating – 4.5/5Professor– Creeper World 3 - https://store.steampowered.com/app/280220/Creeper_World_3_Arc_Eternal/Rating – 9/10Other topics discussedKryten (Red Dwarf character)- https://en.wikipedia.org/wiki/KrytenJohn Goodenough (Oldest Nobel Prize winner at the age of 97)- https://www.abc.net.au/news/2019-10-09/nobel-prize-in-chemistry-for-lithium-ion-battery-development/11588298More facts about the Lithium-ion battery- https://en.wikipedia.org/wiki/Lithium-ion_battery1970s energy crisis (Major industrial countries of the world, particularly the United States, Canada, Western Europe, Australia, and New Zealand, faced substantial petroleum shortages, real and perceived, as well as elevated prices.)- https://en.wikipedia.org/wiki/1970s_energy_crisisElectroBOOM (Iranian Canadian comedian, electrical engineer and YouTube personality.)- https://www.youtube.com/watch?v=TwIvUbOhcKERoast Rabbit (from the Warner Brothers show : Wackiki Wabbit)- https://www.youtube.com/watch?v=6feJ7k36BPkEnergizer lithium ion batteries- https://www.energizer.com/batteries/energizer-ultimate-lithium-batteriesMemory effect (also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium and nickel–metal hydride rechargeable batteries that causes them to hold less charge.)- https://en.wikipedia.org/wiki/Memory_effectNickel Cadmium batteries (type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes.)- https://en.wikipedia.org/wiki/Nickel–cadmium_batteryHow to prolong lithium batteries- https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteriesBaghdad battery (also known as Parthian Battery is a set of three artefacts which were found together: a ceramic pot, a tube of copper, and a rod of iron.)- https://en.wikipedia.org/wiki/Baghdad_BatteryOxford Electric Bell (also known as Clarendon Dry Pile is an experimental electric bell that was set up in 1840 and which has run nearly continuously ever since.

The duo will set their suits to battery power on Friday at 7:50 a.m. when the spacewalk officially starts and exit the Quest airlock. NASA TV begins its live coverage beginning at 6:30 a.m. Once there, the spacewalkers will take about five-and-a-half hours to replace the failed power regulator with a spare BCDU. - https://blogs.nasa.gov/spacestation/2019/10/16/koch-meir-spacewalk-moves-to-friday-as-crew-adjusts-schedule/?fbclid=IwAR2ZuRsNHtKz9ec5c5ZoddN7ecV8juLAgi_lzKzkZubtDjdpDTbgWYL2doISpecial mention: 17 Oct 2019 - The leading solar car competing in the World Solar Challenge has burst into flames, forcing the team out of the race for the first time in 20 years. The solar car — from the Vattenfall Solar Team — caught alight on the Stuart Highway, just south of Port Augusta this morning, just 263 kilometres from the Adelaide finish line. - https://www.abc.net.au/news/2019-10-17/solar-challenge-leading-vehicle-bursts-into-flames/11611112?sf221644014=1&fbclid=IwAR3qWK_7BtjmI0QrWAn8e1BR5-QUN-jXhpNjBD-lopYDeEjBwVrkdVSSQeMRemembrances11 Oct 2019 - Alexei Leonov, Soviet Russian cosmonaut,Air Force major general, writer, and artist. On 18 March 1965, he became the first human to conduct a spacewalk, exiting the capsule during the Voskhod 2 mission for 12 minutes and 9 seconds. He was connected to the craft by a 4.8-metre (16 ft) tether. At the end of the spacewalk, Leonov's spacesuit had inflated in the vacuum of space to the point where he could not re-enter the airlock. He opened a valve to allow some of the suit's pressure to bleed off and was barely able to get back inside the capsule. Leonov had spent eighteen months undergoing weightlessness training for the mission. In July 1975, Leonov commanded the Soyuz capsule in the Soyuz–Apollo mission, which docked in space for two days with an American Apollo capsule. Leonov was an accomplished artist whose published books include albums of his artistic works and works he did in collaboration with his friend Andrei Sokolov. Leonov took coloured pencils and paper into space, where he sketched the Earth and drew portraits of the Apollo astronauts who flew with him during the 1975 Apollo–Soyuz Test Project. Arthur C. Clarke wrote in his notes to 2010: Odyssey Two that, after a 1968 screening of 2001: A Space Odyssey, Leonov pointed out to him that the alignment of the Moon, Earth, and Sun shown in the opening is essentially the same as that in Leonov's 1967 painting Near the Moon, although the painting's diagonal framing of the scene was not replicated in the film. Clarke kept an autographed sketch of this painting—which Leonov made after the screening—hanging on his office wall. Clarke dedicated 2010: Odyssey Two to Leonov and Soviet physicist Andrei Sakharov; and the fictional spaceship in the book is named Cosmonaut Alexei Leonov. He was the last living member of the five cosmonauts in the Voskhod programme. He died from a long illness at the age of 85 in Moscow. - https://en.wikipedia.org/wiki/Alexei_Leonov11 Oct 2019 - Robert Forster , American actor, known for his roles as John Cassellis in Haskell Wexler's Medium Cool, Lebanese terrorist Abdul Rafai in The Delta Force, and Max Cherry in Quentin Tarantino's Jackie Brown, for which he was nominated for the Academy Award for Best Supporting Actor. Forster's varied filmography further includes titles such as Me, Myself & Irene, Mulholland Drive, The Descendants, Olympus Has Fallen, London Has Fallen, and What They Had. He also had prominent roles in television series such as Banyon, Heroes, and Twin Peaks (2017). He won the Saturn Award for Best Guest Starring Role on Television for his performance as Ed Galbraith also referred to as the Disappearer in the Breaking Bad episode "Granite State", reprising his role in the series' sequel film El Camino: A Breaking Bad Movie, which premiered the day of his death. He died from brain cancer at the age of 78 in Los Angeles, California - https://en.wikipedia.org/wiki/Robert_Forster14 Oct 1984 – Sir Martin Ryle, Englishradio astronomer who developed revolutionary radio telescope systems and used them for accurate location and imaging of weak radio sources. In 1946 Ryle and Derek Vonberg were the first people to publish interferometric astronomical measurements at radio wavelengths. With improved equipment, Ryle observed the most distant known galaxies in the universe at that time. He was the first Professor of Radio Astronomy at the University of Cambridge, and founding director of the Mullard Radio Astronomy Observatory. He was Astronomer Royal from 1972 to 1982. Ryle and Antony Hewish shared the Nobel Prize for Physics in 1974, the first Nobel prize awarded in recognition of astronomical research.[6] In the 1970s, Ryle turned the greater part of his attention from astronomy to social and political issues which he considered to be more urgent. He died from a long illness at the age of 66 in Cambridge. - https://en.wikipedia.org/wiki/Martin_RyleFamous Birthdays14 Oct 1801 - Joseph Plateau, Belgian physicist and mathematician. He was one of the first people to demonstrate the illusion of a moving image. To do this, he used counterrotating disks with repeating drawn images in small increments of motion on one and regularly spaced slits in the other. He called this device of 1832 the phenakistiscope. The projection of stroboscopic photographs, creating the illusion of motion, eventually led to the development of cinema. Plateau also studied the phenomena of capillary action and surface tension. The mathematical problem of existence of a minimal surface with a given boundary is named after him. He conducted extensive studies of soap films and formulated Plateau's laws which describe the structures formed by such films in foams. He was born in Brussels - https://en.wikipedia.org/wiki/Joseph_Plateau14 Oct 1927 – Sir Roger Moore, English actor best known for playing British secret agent James Bond in seven feature films from 1973 to 1985, beginning with Live and Let Die. His most notable television role was playing the main character, Simon Templar, in the British television series The Saint from 1962 to 1969. He also had roles in some American television shows and films in the late 1950s and early 1960s, including replacing James Garner and portraying Beau Maverick in the Maverick series in 1960 to 61. Moore starred with Tony Curtis in The Persuaders television series in 1971 to 1972, and had roles in several theatrical films in the 1970s and 1980s. Moore was appointed a UNICEF Goodwill Ambassador in 1991 and was knighted by Queen Elizabeth II in 2003 for services to charity. In 2007, he received a star on the Hollywood Walk of Fame for his work in television and film. In 2008, the French government appointed him a Commander of the Ordre des Arts et des Lettres. He was born in Stockwell, London - https://en.wikipedia.org/wiki/Roger_Moore14 Oct 1946 - Katy Manning, English-Australian actress best known for her part as the companion Jo Grant in the BBC science fiction television series Doctor Who. She has also made many theatre appearances, and is now an Australian citizen. In 2009, Manning moved back to the UK to pursue new acting work and currently lives in London. While she played the part of Jo Grant alongside Jon Pertwee's incarnation of the Doctor, Manning struck up an immediate rapport with her co-stars Pertwee, Nicholas Courtney (The Brigadier), John Levene (Sergeant Benton), Richard Franklin (Captain Mike Yates) and Roger Delgado (the Master). Fans of Doctor Who often refer to these characters as the UNIT family — UNIT, the United Nations Intelligence Taskforce, being the fictional United Nations organisation that the Doctor worked for. Manning is the only surviving Doctor Who companion from Jon Pertwee's era. She was born in Guildford, Surrey - https://en.wikipedia.org/wiki/Katy_ManningEvents of Interest14 Oct 1884 - George Eastman patents paper-strip photographic film. Eastman's invention revolutionized photography by using coated paper and rollers, rather than heavy glass dry plates, to reproduce images. Eastman began looking for ways to "make the camera as convenient as the pencil," after amassing the heavy, complicated, and expensive equipment he needed to keep a picture record of his vacation. This invention allowed him to mass produce a small hand-held box camera filled with rolls of film with 100 exposures. Millions of Americans recorded the first snap shots of their everyday lives using the Kodak camera, which was introduced in 1888.- https://www.uspto.gov/about-us/news-updates/kodak-film-patent-issued-october-14-1884- https://patents.google.com/patent/US306594A/en14 Oct 1892 - Arthur Conan Doyle publishes "The Adventures of Sherlock Holmes" collection of 12 stories originally published serially in "The Strand Magazine". The stories are collected in the same sequence, which is not supported by any fictional chronology. The only characters common to all twelve are Holmes and Dr. Watson and all are related in first-person narrative from Watson's point of view. - https://en.wikipedia.org/wiki/The_Adventures_of_Sherlock_Holmes14 Oct 1926 - Winnie the Pooh was published, written by A. A. Milne and illustrated by E. H. Shepard. The book focuses on the adventures of a teddy bear called Winnie-the-Pooh and his friends Piglet, a small toy pig; Eeyore, a toy donkey; Owl, a live owl; and Rabbit, a live rabbit. The characters of Kanga, a toy kangaroo, and her son Roo are introduced later in the book, in the chapter entitled "In Which Kanga and Baby Roo Come to the Forest and Piglet has a Bath". The bouncy toy-tiger character of Tigger is not introduced until the sequel, The House at Pooh Corner. - https://en.wikipedia.org/wiki/Winnie-the-Pooh_(book)14 Oct 1947 - Chuck Yeager becomes the first person to exceed the speed of sound, Yeager flew the X-1 rocket over Rogers Dry Lake in Southern California. The X-1 was lifted to an altitude of 25,000 feet by a B-29 aircraft and then released through the bomb bay, rocketing to 40,000 feet and exceeding 662 miles per hour (the sound barrier at that altitude). The rocket plane nicknamed “Glamorous Glennis” (after Yeager's wife), was designed with thin, unswept wings and a streamlined fuselage modeled after a .50-caliber bullet. Because of the secrecy of the project, Bell and Yeager’s achievement was not announced until June 1948. - https://www.history.com/this-day-in-history/yeager-breaks-sound-barrierIntroArtist – Goblins from MarsSong Title – Super Mario - Overworld Theme (GFM Trap Remix)Song Link - https://www.youtube.com/watch?v=-GNMe6kF0j0&index=4&list=PLHmTsVREU3Ar1AJWkimkl6Pux3R5PB-QJFollow us onFacebook - https://www.facebook.com/NerdsAmalgamated/Twitter - https://twitter.com/NAmalgamatedSpotify - https://open.spotify.com/show/6Nux69rftdBeeEXwD8GXrSiTunes - https://itunes.apple.com/au/podcast/top-shelf-nerds/id1347661094RSS - http://www.thatsnotcanonproductions.com/topshelfnerdspodcast?format=rssGeneral EnquiriesEmail - Nerds.Amalgamated@gmail.com

Presented by Prof. Matthew Bailes on 30 September 2016. Almost 50 years ago Jocelyn Bell built a new telescope with her supervisor Antony Hewish that had an unusual property: it had high time resolution. The radio sky was thought to only change on long timescales but this new telescope's ability to explore a different regime of phase space meant that it made one of the greatest discoveries in astronomy, that of pulsars. Pulsars are neutron stars, the collapsed cores of once-massive stars. They have been used to perform some of the most accurate experiments in physics, and were the motivation for the construction of the LIGO telescope that recently discovered gravitational waves. In this talk Professor Matthew Bailes will explain how whilst trying to find new pulsars astronomers stumbled across a brand new phenomenon, the Fast Radio Bursts. These millisecond-duration radio flashes appear to be coming from half way across the Universe but nobody knows what they are.

Libby Purves meets crime writer Patricia Cornwell; astrophysicist Dame Jocelyn Bell Burnell; musician Simon Nicol and adventurer Benedict Allen. Patricia Cornwell is a writer. Her new novel Depraved Heart features medical examiner Kay Scarpetta who is working on a suspicious death scene when a story involving her niece Lucy demands her investigative skills. Patricia Cornwell has sold over 100 million books. She sold her first novel, Postmortem, while working as a computer analyst at the Office of the Chief Medical Examiner in Richmond, Virginia. Depraved Heart is published by Harper Collins. Dame Jocelyn Bell Burnell is an astrophysicist and is visiting Professor of Astrophysics at Mansfield College, Oxford. This year she won the Women of the Year Lifetime Achievement Award. She is best known for discovering pulsars, one of the most significant scientific achievements of the 20th century. At the time she was a PhD student in radio astronomy at the University of Cambridge. Her supervisor Antony Hewish went on to win the 1974 Nobel Prize for Physics, sharing it with the head of the group, Martin Ryle. Benedict Allen is an adventurer known for travelling to extremes without backup. He is the only person known to have crossed the Amazon Basin at its widest and completed the first documented journey of the length of the Namib Desert. He will be appearing at The Adventure Travel Show talking about his 3000 mile journey by horse and camel through Mongolia in the 1990s. The Adventure Travel Show is at London's Olympia. Simon Nicol is a founding member of Fairport Convention, joining the band at its inception in 1967. After vocalists Sandy Denny and Iain Matthews left the band, Simon found himself taking a more prominent role on stage. During the 1970s, Simon took a four-year break from Fairport, rejoining in 1976. He has been the band's main guitarist and lead singer ever since. Fairport Convention is on tour from January. Producer: Paula McGinley.

Transcript: In 1967 Jocelyn Bell, a graduate student working at a radio telescope in Cambridge, England, noticed an unexpected source of radio emission that pulsed every one and a third seconds. Through careful detective work she and her coworkers were able to rule out artificial sources for the radio waves and proved that they came from a celestial source. Radio pulsing stars were unexpected and unanticipated. If the pulse was due to rotation, the size of the star must be less than five thousand kilometers, making them much smaller than normal stars. For a while she and her group jokingly referred to the objects as LGM 1, 2, 3, and so on, where LGM stood for Little Green Men. They were not alien signals, nor were they artificial. Pulsars were the long sought after neutron stars. Antony Hewish and Martin Ryle, heads of the labs at Cambridge, received the Nobel Prize for this discovery. Controversially, Jocelyn Bell who actually made the discovery did not share in the Nobel Prize.

Si Emilio García y Pablo Santos abrieron este ciclo dedicado a la mujer en la ciencia hablándonos de mujeres dedicadas a la ciencia de la talla de Hildegard von Bigen, Rosalind Franklin, Barbara McClintock o Rita Levi Montalcini, lo van a cerrar hablándonos de Jocelyn Bell, descubridora junto a Antony Hewish de una notable clase de objetos, los púlsares. Después de repasar ese momento histórico, en el que llegó a plantearse la posibilidad de que los púlsares no respondieran a una señal natural, sino a los _little green men_ (hombrecillos verdes), habaremos con Pepa Masegosa, del IAA-CSIC, sobre la situación actual de las mujeres astrónomas en el panorama nacional y sobre cuales pueden ser las vías para romper definitivamente el techo de cristal. También hablamos con Francesca Figueras, de la Universidad de Barcelona, sobre los objetivos del Año Internacional de la Astronomía 2009 de cara a la equiparación de género, y concretamente sobre el proyecto _Ella es una Astrónoma_ que Francesca coordina. Y para terminar, un estimulante, y como siempre, único, reportaje a pie de calle de nuestro Reportero Urbanita acerca de mujeres en la ciencia. No os lo perdais, porque se realizará, en directo, un doble cambio de sexo en el estudio, algo que no creemos que se haya hecho jamás antes en radio.
