Talk:Chandra Wickramasinghe

message: Professor Nalin Chandra Wickramasinghe, BSc (Ceylon), MA, PhD, ScD (Cantab), Hon DSc (Sri Lanka, Ruhuna), Hon DLitt (Tokyo, Soka), FIMA, FRAS, FRSA
Director of the Cardiff Centre for Astrobiology, Cardiff University
Professor Chandra Wickramasinghe was born in Sri Lanka and was educated at Royal College, Colombo and later at the University of Ceylon. In 1960 he obtained a First Class Honours degree in Mathematics and won a Commonwealth scholarship to proceed to Trinity College Cambridge. He commenced work in Cambridge on his PhD degree under the supervision of the late Sir Fred Hoyle, and published his first scientific paper in 1961. He was awarded a PhD degree in Mathematics in 1963 and was elected a Fellow of Jesus College Cambridge in the same year. In the following year he was appointed a Staff Member of the Institute of Astronomy at the University of Cambridge. Here he began his pioneering work on the nature of Interstellar Dust, publishing many papers in this field that led to important paradigm shifts in astronomy. He published the very first definitive book on Interstellar Grains in 1967. In 1973 he was awarded Cambridge University’s highest doctorate for Science, the prestigious ScD.
Chandra Wickramasinghe is acknowledged as being one of the world’s leading experts on interstellar material and the origins of life. He has made many important contributions in this field, publishing over 350 papers in major scientific journals, over 75 in the high-impact journal Nature. In 1974 he first proposed the theory that dust in interstellar space and in comets was largely organic, a theory that has now been vindicated. Jointly with the late Sir Fred Hoyle he was awarded the International Dag Hammarskjold Gold Medal for Science in 1986.
Chandra Wickramasinghe was a UNDP Consultant and Advisor to the President of Sri Lanka in 1982-84, and played a key role in the setting up of the Institute of Fundamental Studies in Sri Lanka. In 1983/84 he was appointed the founder Director of the Institute of Fundamental Studies by President J.R. Jayawardene. In 1992 he was decorated by the President of Sri Lanka with the titular honour of Vidya Jyothi. He was awarded the International Sahabdeen Prize for Science in 1996.
In 1973 he was appointed Professor and Head of the Department of Applied Mathematics and Mathematical Physics at University College, Cardiff, being the youngest Professor appointed at the University upto that time. He was responsible for starting an Astrophysics research group in Cardiff under the auspices of a new Department that was formed under his headship, the Department of Applied Mathematics and Astronomy. He remained Head of this Department until 1989 by which time the Astronomy Research School in Cardiff was regarded as being one of the best in the UK. From 1989-1999 he has held the post of Professor of Applied Mathematics and Astronomy within a newly structured School of Mathematics at Cardiff University of Wales. In the year 2000 he was appointed Director of the newly formed Cardiff Centre for Astrobiology.
He is an award-winning poet and the author or co-author of over 25 books and over 350 scientific papers. He has held visiting professorial appointments in a large number of Universities world-wide. In recognition of his extensive contributions to science and culture he was awarded an honorary doctorate by the Soka University of Tokyo, Japan in 1996.
He was the John Snow Memorial Lecturer and John Snow Medallist of the Association of Anasethetists of Great Britain and Ireland in 2004.
He was awarded the degree of Doctor of Science (Honoris Causa) by the Unversity of Ruhuna, Sri Lanka in 2004.

message: This is one of the most biased biographical articles I've seen on WP in recent times. The article subtly (and not so subtly) pushes the panspermia POV without even a passing mention of the many and wide criticisms of it or, more importantly, the complete lack of supporting evidence. I also note that there is no mention of Prof. Wickramasinghe even more fringe views and activities such as co-authoring a paper claiming that an Archaeopteryx specimen was a fake created by pressing chicken feathers into wet plaster surrounding a Compsognathus skeleton. 124.148.211.236 (talk) 07:20, 28 March 2012 (UTC)

thread_title:  OK, let's criticize panspermia then! 

message: I would like to introduce myself to people interested in this page, and request their support as  I argue the case to make this page reflect the work of this brilliant man. A few nights ago I accidentally posted this message to the Editor on the wrong WIKI Talk: page. I would like to redocument these thoughts to  share my feelings with people interested in this page.  
There is much derogatory material being collected here http://en.wikipedia.org/wiki/Chandra_Wickramasinghe which seems not to be in the spirit of Wikipedia, nor (I trust) intentionally abusive. Some of it is close to libelous.
I am currently close to completing a submission to the UK National Honours Nomination process to recommend Chandra Wickramasinghe for the highest UK honour. I have received a set of letters of reference from some (10) of the top scientists in the UK.
Unfortunately most young Americans have no understanding or knowledge of this man or the process by which he ended up in the 1960's studying under Sir Fred Hoyle. At the time Fred Hoyle was the Michio Kaku of the UK MIT - ie Cambridge University. Fred was a peer of Sir Herman Bondi and was in the generation who followed Einstein. These were the creme de la creme of the best brains in Britain and across the old British Empire (The Commonwealth).
Every year or two, we would hear of a new young PhD student coming from Asia to study science at Cambridge. These winners of Commonwealth scholarships were usually brilliant - if not often geniuses. They were greatly admired and respected. It is this history of respect that has caused me to be so distressed at some of the seriously incorrect and derogatory material floating round the internet - and especially on this Chandra Wickramasinghe's WIKIPAGE. To imply the things that this WIKIPAGE does is close to unforgiveable.
All I can do is work within your WIKIPEDIA system to improve the material. As you ask me to provide proof of my suggested changes, I ask only that the editors provide proof of their existing material.
I was planning to begin this process by correcting the University where he currently is based. Then I would like to address the most critical of paragraphs - his connection to the Creationists v. Darwinists debate.
Understand that I put Chandra Wickramasinghe in the same category as Galileo, and believe that the rapidly emerging knowledge around extraterrestrial microbial life - which accelerates due to the latest developments in the ALMA results, will finally be proven by the 2014 Rosetta Mission and then (if NASA fund it) the 2019 MARS Icebreaker Mission. I believe it is critical NASA approve this "search for current life" mission.
Many will know that Dr Chandra is in his 70's and retired from full time academic teaching. The good news is that he is in costant demand to lecture and speak on TV Shows and Radio Shows across the world. For this reason I have suggested to him that we ask WIKIPEDIA editors to allow us to restructure his site - and we are proposing that we use Michio Kaku's page as a template. 
==== The Plan for the next 2 weeks ====
I will be creating a full page off-line in WORD, and working hard with citations and "proof" of every change from the original that you see today. 
I realize there are one or two people, who for whatever reason, wish to present a very negative view of this amazing scientist. I am happy to talk on the phone or SKYPE to those people to better understand where you are coming from. For Editors who only want the truth, I will work diligently to deliver the citations and proof of any changes.
==== Request to Immediately correct his latter employment history ====
I would like to refer a few people to this report on the BBC of a retirement party in Cardiff University on 7 Sept 2006 Retirement Party of CW 7 Sept 2006:  I hope you can see why the last part of the Education section is wrong. 
It reads (incorrectly - and has been incorrect for years):
 ..... and Professor and Director of the Cardiff Centre for Astrobiology (1999-2011), now a private company and charity.[1]
It should read : 
Professor of Applied Mathematics and Astronomy, University of Cardiff, Wales, UK (1990-2006)
Professor and Director of the Cardiff Centre for Astrobiology, University of Cardiff, Wales, UK (2006-2011)
Professor and Director of the Buckingham Centre for Astrobiology, University of Buckingham, UK (2011- )
If no-one objects after following the citation, I will update the paragraph tomorrow. I am working though on the new page off-line over the next 2 weeks. 
PS I am not being paid. Like  Xenophon the student of Socrates, I am just wanting to see Wikipedia reflect true history.

thread_title:  Request to Immediately correct his latter employment history 

message: My personal preference would be to delete this whole paragraph. But in the spirit of my WIKI responsibility (esp to BatteryIncluded I have crafted the following as a replacement. The goal is to openly discuss what really happened. 
Background : 
Wickramasinghe is a respected UK Buddhist and regularly gives lectures to his community on the role of Science from a Buddhist perspective. It is not generally appreciated that Buddhists do NOT believe in God. Buddha just like modern sociologists and psychologists, believed that religious ideas and especially the “god idea” have their origin in fear. Buddha says: “Gripped by fear men go to the sacred mountains, sacred groves, sacred trees and shrines” 
 said Chandra Wickramasinghe.
This quote has been misunderstood as CW's support for the idea of “god-like” intervention in the seeding of life (on earth, in the galaxy or even in other galaxies). 
In fact what Wickramasinghe was expressing was two fold :
1. it was a message to his fellow astrophysicists that it was time to bring the disciplines of biology into the world of astrophysics and chemistry
2. it was his message to chemists that it was only though his arrogance and ignorance that man thought he might be able to “create life” in a laboratory.
Wickramasinghe's own personal belief is that the age of the universe might just be sufficiently ancient that somewhere, just once, the highly improbable conditions 
for the evolution of an “organism on the edge of LIFE” actually happened. This moment, which Wickramasinghe attributes to the laws of probability, not to "GOD"  saw the start of evolution which soon (using Darwin's theory of evolution) delivered viruses and nanobacteria. In this quote, Wickramasinghe was expressing a personal perspective to Life and its mysterious first seeding. From that first moment, Panspermia takes over and hypothesizes a promulgation of this “seed of life”.
The 1981 scientific creationist trial in Arkansas: 
Previous to the trial, a group of supporters of Panspermia, who happen to also have a belief that the universe is ageless, evolved a theory they called Cosmic ancestry. This is quite separate from Panspermia. 
At the time, Wickramasinghe was disturbed by the polarization of the debate. He was distressed that the Creationists fundamentally did not want Darwinism taught to their children. But he was also disturbed that Darwinism was being taught as "the truth" - rather than an evolving hypothesis - a good approximation to the evidence. His own personal belief was that Panspermia and the inflow of microbes to the earth had an effect on evolution, as yet not clearly understood.   In his desire to help his "supporters" argue their right to teach their children modified-Darwinism, Wickramasinghe agreed to attend and support the "creationists" argument against the official Darwinism . Wickramasinghe presented a passionate argument for his own vision which was not "creationism" nor "Darwinism". It was a vision than the future should embrace open debate of alternate hypotheses.  — Preceding unsigned comment added by 96.54.204.240 (talk) 07:11, 15 July 2013 (UTC)

thread_title:  Creationism v. Darwinism  

message: The early sentence : Nalin Chandra Wickramasinghe (born 20 January 1939) is a Sri Lankan-born British mathematician, astronomer[1][not in citation given]
Could you guide me on how best to "prove" a person is an astronomer. Sir Arthur Clarke said : Sir Arthur C Clarke: "Chandra is one of the foremost astronomers in the world today, and, as evidenced by his impressive curriculum vitae, a leading light in British astronomical research. 
He has made fundamental contributions to the study and understanding of cosmic dust. 
Together with the late Sir Fred Hoyle, Chandra developed the theory of cosmic life —
suggesting that life on Earth arrived from outer space, where life is constantly being 
seeded on planets. These theories have fuelled controversies in several branches of
science, which helped advance the frontiers of knowledge and scientific discourse".
If we just choose one : Professor and Head of the Dept.of Applied Maths and Astronomy, Univ. Coll., Cardiff, 1973-89
I would feel this a valid "proof" but how to cite it? Advice appreciated.
He also has PhD in Astrophysics, 1963 : from possibly the most prestigious University in the World - Cambridge UK

1. I have never met Chandra Wickramasinghe
2. I have no connection to him or his family
3. I live in Canada and he lives in UK
4. I would love to meet him
5. I was motivated to help improve what I saw on Wikipedia as a very imbalanced attitude to CW and his work especially Panspermia; plus lack of knowledge of the man, and his scientific work. 
6. I believe "Life is a Cosmic Phenomenon" and ever since I was taught relativity by Herman Bondi in the 60's , I have admired the vision and science of Fred Hoyle and CW
7. by the way everything I say above applies equally to Fred Hoyle
8. I believe scientists should be free to hypothesize anything they believe in and that the whole concept of "fringe science" restricts our scientific development and should be reassessed
9. It is time for NASA to change its mantra from "The search for Water" to "The search for Life". Especially as that is what they are doing.
10. I believe it is time for the biologists to get together and define what "Life" is.
Yours

You might also mull over the fact that Sir Arthur C. Clarke lived in Sri Lanka where CW was from. There is a story told that the head of the USA CIA/NSA was having a glass  of wine one night with Clarke (ever wonder where the idea for 2001 Space Odyssey really came from). 
He looked up at the bookcase and spotted all the books of Hoyle and Wickramasinghe.
"These guys are the only ones who have figured out what is going on", he said to Clarke.

Polonnaruwa[edit source | editbeta]
Main article: Polonnaruwa (meteorite)
On December 29, 2012, a team led by Wickramasinghe claimed to have found a meteorite in a rice field near Polonnaruwa, a city in east-central Sri Lanka. Publishing in the fringe science Journal of Cosmology, the team explained that the object that they had found contained diatoms and was hence solid evidence for the theory of panspermia.[47][48][49][50] Independent experts in meteoritics, however, determined that the object found by Wickramasinghe and his team, owing to a porousness not found in other confirmed meteorites, was not truly of extraterrestrial origin,[51][52] instead being created by lightning strikes on Earth.[53] In addition, experts in diatoms observed that, while the organisms found by Wickramasinghe were indeed living, they represented a wide variety of extant terrestrial taxa, and for that reason their presence in the alleged meteorite was the result of contamination from the wet environment of the rice paddy where it was found.[51][54]
There are many inaccuracies in this paragraph which we can and should improve. Perhaps you can use some of the following facts: Journal of Cosmology, Vol. 22, No. 2 published, 5 March 2013.
#Meteorite distribution from the comet was over 10 km
#Police collected samples and submitting them to the Medical Research Institute of the Ministry of Health in Colombo, Sri Lanka
#Sample of rocks was sent to W.and his team in Cardiff U.
#Preliminary results from Scanning Electron Microsope showed diatom frustules embedded deep in rock matrix which was not consistent with contamination
# second sample was sent to NASA Marshall Space Flight Center and same results and conclusion by independent team
#GC-MS spectra was used to conclude it was likely classified as a “carbonaceous chondrite ungrouped”
#Substantial number of stones was gathered by Department of Geology, University of Peradeniya
#a month later 628 fragments were sent to Cardiff. But only 3 were deemed to be possible meteorites
#Further analysis was done on the original sample. This fragment was portioned for interior section Scanning Electron Microscopy (SEM), oxygen isotope analysis, compositional analysis by X-Ray Diffraction (XRD) and elemental analysis by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) plus a sample of sand fulgurite was also analysed for comparative purposes
#The fulgurite hypothesis  was disproved by the fact that the mineral lechatelierite (which comprises fulgurites) has an average density of 2.57 g cm-3, whereas the density of the Polonnaruwa meteorites is <1 g cm-3.
#The study concluded that the oxygen isotope data show P159/001-03 and P/159001-04 are unequivocally meteorites, almost certainly fragments originating from the fireball-causing bolide. 
#The most likely origin of this low density meteorite with delicate structures, some highly carbonaceous, is a comet.
The Bad Astronomer blog that you cite was written before the main reports were even completed. I am concerned about citing this source.
Where did you get the "wet paddy field" idea from?

BSmith has sanitized Dr. Wickramasinghe's biography by removing all of his more fringe speculations and giving more weight to Wickramasinghe's POV (especially regarding the Polonnaruwa case). Although like you I feel that it is important that scientific and fringe views are treated fairly and clearly identified as such to the reader, I think that we can yet work productively with BSmith821. I'm not one of the civility robots one finds on conduct and RfC pages, but I feel that it is important to make all attempts to work cooperatively with a user rather than immediately lambast them. Plus, I have no desire to subject someone like BSmith, who is by no means a nutjob or a troll, to the useless, bottom-feeding mutual masturbators who spend their time on AN, AN/I, AE and the related pages, and hope that we can resolve the issue without the pressure cooker blowing off.

My feeling is that this article should be cut down to a simple biography and most of the content that would be better suited to panspermia or other related topical articles should be removed. That Wickramasinghe promotes maverick science proposals should be discussed, but the details of these proposals are not relevant to this biography.

replies: text: User BSmith was relentless on inserting Chandra's most fringe speculations and methodologies into panspermia, he then kept a lower profile there after an ANI was filed, which he dodged. So no, transferring that back to panspermia is not an useful option. Cheers, BatteryIncluded (talk) 00:06, 12 August 2013 (UTC)

text: You are right, BatteryIncluded. None of the material should be moved back to the panspermia article, which describes a scientific hypothesis that is actually legitimate. Wickramasinghe, on the other hand, creates "propositions" that are somewhat out of line with the evidence, but not irreparably flawed, and uses these postulates in order to derive wildly inappropriate and unsupported conclusions.

replies: text: Yeah, I get your drift, but panspermia as a "legitimate scientific hypothesis" is a bit overplaying its hand. It's more of a plausible speculation for which no corroborating tests, observations, or experiments have yet been developed to affirm or falsify the basic idea. In the future, we may find it to be more compelling and maybe even scientifically viable, but for the time being it acts as a placeholder for "things we just don't have enough evidence to say much of anything about". That Hoyle and Wickramasinghe have famously crawled way out on limbs in this direction is rather notable considering that there is almost no other work that has been done on the topic that is serious. I agree that to over-emphasize their ideas on panspermia is not necessarily the best idea, but the ideas really ought not be expounded upon at this biography page either as the content is overwhelming the much more notable contributions relating to carbonaceous gains in the ISM, for example. Outright removal of the WP:FRINGE suggestions may be the best option as there is little to no independent notice of Wickramasinghe's proposals. jps (talk) 18:52, 31 August 2013 (UTC)

text: I don't feel that the FTN notice will be quite helpful, given that such noticeboards are often actively watched by vandal revertors and POV warrriors who lack any clue on how to accurately and neutrally present science and fringe theories. I may well be wrong, especially if some actual scientists actively monitor that board. Wer900 • talk 05:07, 12 August 2013 (UTC)
