25.01.2022 Sirs William Bragg, father and son. Rename Cross road to Sir William Bragg Avenue.

25.01.2022 I agree with the sign. Exit Cross Road, enter Sir William Bragg Avenue.

22.01.2022 William Henry Bragg (the father), obviously enjoying a joke. Call Cross Road William Bragg Avenue

21.01.2022 Ok, Ok, so the Braggs won a Nobel prize in physics. But what have they done LATELY? Part 2: "In 1915, senior British officers learned of experiments by a pair of French physicists who were attempting to develop a method to locate the position of enemy guns based on the times the sound of an explosion arrived at different locations. Bragg was seconded to investigate. He had moved from Adelaide in Australia to England when his father, William Henry Bragg, had taken a position a...t Leeds University. The son then went to study mathematics at Cambridge in 1909, joining a cavalry unit as a way to make friends in the unfamiliar town. When war broke out, he signed up and was commissioned as a second lieutenant. However, the reality of serving was not as he hoped, and when, out of the blue he was asked to take on the task of investigating whether sound-ranging could become a practical reality, it made him, he later recounted, walk on air. It was an inspired choice by the British. By 1818, Bragg’s sound-ranging system was a vital element in negating the German guns at Amiens, in, as one soldier put it, the black day of the German army.

20.01.2022 Fun Fact #4 about Cross Road Cross Road is also known as route A3. Glen Osmond Road is route A1, South Road is A2 There is No A4!!, Anzac Highway is A5, and Sir Don Bradman drive A6 Sir William Bragg Avenue should be the A3

20.01.2022 William Lawrence Bragg (or William Henry Bragg) may or may not have said this. Brian Clegg (Build your own time machine) thinks Daniel Kevles thinks so, who in turn says that David Webster said so in an interview...... Rename Cross Rd to Sir William Bragg Avenue.

20.01.2022 Cross Road runs from Glen to Glen: Glen Osmond to Glen Elg. Rename Cross Road to William Bragg Avenue (after the most famous Australian-born Physicist in the history of the Universe.)

19.01.2022 What happened to the Bragg Laboratories Darling? The former Bragg Physics Laboratories have been renamed the Darling West Building! No love lost. Rename Cross Road to Sir William Bragg Avenue

17.01.2022 Fun Fact #7 about Cross Road. If you re-arrange the letters selected from all of Cross Roads former names, viz High Terrage, Vapier Terrace, South Werrace, Glen Osmond Broad, and Plymption Terrace, they can spell out Sir William Bragg Avenue! Rename Cross Road to Sir William Bragg Avenue

17.01.2022 Fun Fact #8 about Cross Road. There are 80 streets that run off Cross Road (not counting the A1/M1, A2, A5, A14, B28 and Unley and Goodwood Roads), and 19 of them begin with either the letter W or H. Rename Cross Road William Bragg Avenue.

16.01.2022 I contacted 4 local State MPs about renaming Cross Road. They replied as follows: *David Pisoni, [Unley] replied Crossroad is a State road: the naming of State roads is the responsibility of the Department for Transport, Energy and Infrastructure (DTEI), while public roads are the responsibility of the local councils. It is recommended that you contact your local member of Parliament, who will be able to further investigate this on your behalf and liaise with the Departm...ent in relation to your proposal. I replied thanking them and advising the facebook page * Sam Duluk, [Waite] (replied: on your behalf, I have written to the Minister of Transport, Infrastructure and Local Government to lobby for the change in name from Cross Road to Sir William Bragg Avenue.) 29 March 2019 I replied thanking them and advising the facebook page: 4 April * Carolyn Power (replied: As the Member for Elder, I would recommend that you contact your local Member for Badcoe should you require further assistance on this issue. Further correspondence from you on these same matters will be filed. I wish you all the best with your enquiry.) *Jayne Stinson 22 March 2019 [member for Badcoe] She replied: agrees that the Braggs are impressive S.Australians. Let me know when you hear back from SA DPTI. I replied thanking them and advising the facebook page I also enquired of the SA Department of PTI 22 March 2019 (email acknowledged with a tracking number for this submission). Having received no further reply, I resent my question on May15. I also sent the letter to Minister Stephan Knoll MP (Minister for Transport, Infrastructure and Local Government Minister for Planning. (I received an automated response of receipt). Hence a general lack of interest from everyone. (I will keep on niggling them)

16.01.2022 Fun Fact #2 about Cross Road: There are 277 plane trees planted on its footpaths between South Road and Unley Road. That is what qualifies it as an Avenue rather than a road.

13.01.2022 Many of Cross Rds residents have been letterboxed with a letter suggesting that Sir William Bragg Avenue replace the name "Cross Road". When the Minister for planning replied to my initial enquiry (pouring cold water on it) he stated that: "the Commissioner of Highways would need to....consult with approximately 1000 affected residents and businesses in line with the Public Consultation Policy requirements of the Act. Given that there are three Councils affected and a large number of properties the consultation phase of such an initiative would be significant." He was right! the consultation phase is significant. Nevertheless, I have begun it for him.

12.01.2022 William Lawrence Bragg (in 1960), looking at a molecular model. Rename Cross Rd to "William Bragg Avenue"

12.01.2022 (WH Bragg in 1909) When the radium-containing mineral carnotite was discovered at the Moonta mine, Bragg seems to have been the only authority in Adelaide at that time (1906) to possess an electroscope that could be used to test for radioactivity. Consequently he was drawn into the search for uranium mineral in Moonta, Olary and Mt Painter. Rename Cross Road to "William Bragg Avenue".

12.01.2022 The responsible Dept is filling the gaps left by dead trees. From these little trees, big trees grow. Trees make this road an avenue. Rename Cross road to Sir William Bragg Avenue.

12.01.2022 OK, so what did the Braggs do to deserve their 1915 Nobel Prize in Physics? Braggs law of x-ray diffraction Dates from 1912 & 1913. (It addresses the measurement of the distance between two adjacent layers of atoms in a crystal. This is done by comparing the distance travelled by x-rays (whose wavelength is known) that are reflected from one layer, with the distance travelled by those reflected from the adjacent layer of atoms). In words: When the path difference is a whol...e number of wavelengths, the two reflected beams of x-rays will reinforce (ie produce a maximum of x-ray intensity) at an angle which can be measured. The sine of this angle is: a whole number of wavelengths (ie one or two) divided by twice the distance between layers of atoms! This is the basis for modern x-ray crystallography which can determine the atomic structure of molecules. (As Richard Feynman said in reply to an invitation to explain to the layman, what his Nobel prize was for: If I could explain it to the average person, it wouldnt have been worth the Nobel Prize.)

11.01.2022 William Lawrence Bragg with sister Alice in Adelaide in 1904, just 11 years before he was awarded the 1915 Nobel prize for Physics (jointly with Dad). Rename Cross Road to Alice - I mean William Bragg Avenue.

11.01.2022 Below is my response to the Ministers reply to my original letter proposing a name change for Cross Road. Dear Minister Knoll Thank you for the consideration given to my proposal and for your reply.... The current name Cross Road which is assigned to the A3 road is a change from its previous name of Cross Roads (plural) in 1949 when it was the aggregation of the local street names: High Terrace, Napier Terrace, South Terrace, Glen Osmond Road, and Plympton Terrace, hence is about 60 years old. I am aware that the renaming of Cross Road to Sir William Bragg Avenue would require changes to the infrastructure that are not insignificant (indeed some of the lettering on existing signs is in a poor state and requires replacing). However the degree of inconvenience and cost is not dissimilar to that incurred when in 2001, 6km of Burbridge Road was renamed Sir Donald Bradman Drive. So a precedent exists. In fact there are fewer businesses along Cross road to be inconvenienced, than there were along Sir Don Bradman Drive when the name change occurred. The residents of Cross Road may in fact welcome the added prestige of residing on a road that is named Sir William Bragg Avenue. Furthermore, cost should not be a major concern when a change such as this is made to honour a very significant South Australian and to raise the profile of Australian science is contemplated, as evidenced by the costs associated with changing the name, stationary, websites and signage of State Government Departments after a change in Government. I am also aware that the Commissioner of Highways would need to: 1. Consult with all Councils affected. I have already written to the 6 Unley Councillors (and Unley Council), the 6 Mitcham Councillors (and Mitcham Council) and the 4 Marion Councillors whose wards are adjacent to Cross Road. Hence the consultation process has begun. 2. Consult with the affected residents and businesses. In the near future, I propose to letter box the residents and businesses along Cross Road to float the idea with them, along with the reasons for a name change.

11.01.2022 If a vacant lot on North Terrace can be called "Australian Bragg Centre", Cross Rd can be renamed. Rename Cross Road as William Bragg Avenue. What even is PROTON THERAPY?

09.01.2022 William Lawrence Bragg at 25, was the youngest Nobel Prize winner in Physics (still is). He was so young that he was the first person to reach his 50th anniversary celebrations (alive) and was able to give the first ever Nobel guest lecture. This unique achievement is reason enough to name a major road (such as Cross Road) after him. (There he is in the middle)

09.01.2022 I have received a reply from the Minister for Transport, Infrastructure and Local Government to my proposal to rename Cross road. The reply said: If a proposal was to be considered for the renaming of this road, under the directions contained in the Act, the Commissioner of Highways would need to: consult with all Councils affected, as the Act states that if the road crosses... Council boundaries, any other Council involved with the road needs to be consulted on the change and given at least 2 months to respond; and consult with approximately 1000 affected residents and businesses in line with the Public Consultation Policy requirements of the Act. Given that there are three Councils affected and a large number of properties the consultation phase of such an initiative would be significant. If the renaming proceeded to implementation, all departmental signage that points to Cross Road would need to be altered and businesses would need to amend stationery, business directories, signs and web sites to recognise their new address. All government and private maps would also need to be upgraded. Further, there is a degree of inconvenience and direct cost to all private residents who will be required to update their address. Overall, the community cost is significant. While I appreciate this matter is important to Mr Caon, Cross Road is a long standing name, well known to the greater community of Adelaide. For this and the above reasons of inconvenience and community cost, I have determined that the benefits of the proposed initiative are not sufficient to warrant the change in name at this stage. I will prepare a reply to the Ministers response. (The photo: autumn colours on Cross Road as the plane trees lose their leaves)

09.01.2022 Braggite is the first mineral discovered with the assistance of X rays (in 1932). Consequently it was named after William Henry Bragg (18621942) and his son, William Lawrence Bragg (18901971). Braggite is a sulfide mineral of platinum, palladium and nickel with chemical formula: (Pt, Pd, Ni)S. Even geologists think the name Bragg is worth commemorating. Rename Cross Road William Bragg Avenue.

09.01.2022 The distance between atoms is comparable to the wavelength of x-rays. William Henry and William Lawrence Bragg showed how to use a diffraction pattern to determine the structure of a crystal. In February 2020, researchers in China used X-ray crystallography to determine the structure of the covid19 causing Coronavirus. Rename cross road to William Bragg Avenue.

08.01.2022 Recognise Scientists by renaming Cross Road "Sir William Bragg Avenue". Fun Fact #6 about Cross Road Marion City Council has planted 40 lemon scented gums (Corymbia citriodora, aka eucalyptus citriodora.) in the Cross Road median strip between South Rd and Marion Rd. (FYI: Many naturalists and conservationists do not recognise the Corymbia genus and still categorise its species within Eucalyptus. Corymbia is a genus of about 113 species of tree that were classified as Euc...alyptus species until the mid-1990s. It includes the bloodwoods, ghost gums and spotted gums. The bloodwoods had been recognised as a distinct group within the large and diverse Eucalyptus genus since 1867. Molecular research in the 1990s, however, showed that they, along with the rest of the Corymbia section, are more closely related to Angophora than to Eucalyptus, and are probably best regarded as a separate genus. All three generaAngophora, Corymbia and Eucalyptusare closely related, often difficult to tell apart, and are still commonly and correctly referred to as "eucalypts".) See more

07.01.2022 Ok, so what did the Braggs do to earn their Nobel prize? (Part 2) The Bragg equation!!! 2dSin(theta) = n(lambda)... This means that when the difference in distance travelled by the x-ray beam reflecting from one layer of atoms and the x-ray beam reflecting from the adjacent layer (the left hand side) is equal to a whole number of wavelengths (the right hand side), then the two reflecting beams reinforce each other to produce a bright spot (rather than a dark spot). This has got to be worth having an Avenue of Plane trees named after you,,,,,

07.01.2022 More street trees planted along Cross Rd, east of Fullarton Rd. This makes it more like "Cross Avenue" than Cross Road. Just call it Sir William Bragg Avenue.

07.01.2022 66 of these straggly trees have been planted on the north side of Route A3, between Marion Rd and South Rd. (and 132 posts and 66 envirowells). I could think of any number of better avenue trees to have used! Rename the A3 to Sir William Bragg Avenue.

06.01.2022 Fun fact #5 about Cross Road. It is the only metropolitan Adelaide road with 3 rail level crossings! Two train and one tram. Sir William Bragg Avenue, the only road with 3 rail level crossings!

06.01.2022 Below is a letter that I have sent to 16 local councillors, 4 local state MPs, the SA Department of Planning, Transport and Infrastructure, The Eastern Community Messenger. I will let you know how they reply.... "Changing the name of Cross Road to Sir William Bragg Avenue" Why William Bragg should have a major road named after him (them).... William Lawrence Bragg (and his father William Henry Bragg) were residents of Adelaide and were jointly awarded the Nobel prize in physics for 1915 (for work on x-ray diffraction). WH Bragg was professor of mathematics and physics at Adelaide University and knighted in 1920. His son, WL Bragg was born in Adelaide and graduated from Adelaide university before moving with the family to the UK WL Bragg was knighted in 1941. Theirs was the first Nobel prize in physics awarded to Australians. The second was awarded to Prof Brian Schmidt in 2011. Hence awarding a Nobel prize in physics is a rare, one-in-a-hundred-year event. WL Bragg at 25 years of age, was, and remains the youngest ever Nobel laureate. These achievements warrant acknowledgment with the naming of an avenue after this duo. Naming the avenue Sir William Bragg Avenue would be sufficient to acknowledge both father and son. Both shared the same name and the Nobel prize, both were knighted, both were professors of physics/mathematics. And both lived in Adelaide. It is common practice in Adelaide and in overseas cities to name major thoroughfares after prominent citizens. In Adelaide we have Sir Donald Bradman Drive; Sir Lewis Cohen Avenue; Sir Edwin Smith Avenue as examples. Scientific achievement is not given sufficient prominence in our society and I believe it would be timely to do so by renaming Cross Road after these world-famous Australian scientists who have such a strong connection with Adelaide. Why Cross Road is suitable for renaming The name Cross Road has little historical significance that would be lost by a renaming. Nor does the name incorporate the destination it leads to, as for example Henley Beach Road does. In fact it was known as Cross Roads before the plural was dropped. And before that different sections had different names such as High Terrace, Napier Terrace, South Terrace, Glen Osmond Road and Plympton Terrace. After its re-development into a dual carriageway, the present Cross Road is an imposing avenue of mature plane trees. An avenue such as this is grand enough to bear a grand name and I believe that the Braggs are sufficiently accomplished to have a grand avenue named after them.

05.01.2022 Ok, Ok, so the Braggs won a Nobel prize in physics. But what have they done LATELY? Australian Nobel laureates wartime inventions honoured by US Army physicist. Adelaides William Lawrence Bragg recognised as acoustic pioneer. Phil Dooley reports: [Part one] Australian-born physicist William Lawrence Bragg, the youngest ever winner of the Nobel Prize for Physics, is set to be honoured for his work on sound waves at a meeting of the US Acoustical Society of America (ASA) in ...Kentucky, in May this year (2019). Bragg (1890 to 1971) also earned the Military Cross and an OBE for his work during World War 1. His story will feature in a tribute to the pioneers of sound to be presented at the ASA conference by US Army acoustic physicist Daniel Costley. Bragg encouraged the innovation that solved a lot of the practical problems, Costley says. By the end of the war, Bragg had taken sound-ranging from a barely-functional idea to a technique that could pinpoint enemy guns to within 25 metres, and was implemented by battalions as far afield as Palestine.

05.01.2022 Of the 16 Councillors from Unley, Mitcham and Marion Councils to whom I sent emails notifying them that the name Cross Road should be changed to Sir William Bragg Avenue, 13 ignored it (perhaps it went to spam). I take this response to mean Who cares, none of my business. J Masika from Marion replied thanking me for an appreciation of the history of Cross Road. Both of my local Unley councillors replied and advised that road naming was the responsibility of the DPTI. They also said, dont hold your breath (I paraphrase).

04.01.2022 Fun fact #3 about Cross Road. [Hopefully soon to be aka: "Sir William Bragg Avenue" It is 8.77 km long and falls from 148m above sea level to 14m asl. A slope of 1.5%

02.01.2022 William Bragg Avenue, not Cross Road. More than a 100 years ago William Bragg was born in Adelaide, graduated from Adelaide University and was awarded the 1915 Nobel Prize in physics. The first Nobel awarded to an Australian. This should be commemorated by naming an arterial road after him (and his father). Do you agree?

02.01.2022 William Henry Bragg - the father (in 1909) and senior Nobel prize winner in physics. Did you now that he was the Professor of at Adelaide University? Rename Cross Road to William Bragg Avenue.

02.01.2022 Sir William Bragg Avenue roaring with traffic. Rename Cross Road

01.01.2022 (Photo from the Nobel Foundation archive.) Born: 31 March 1890, Adelaide, Australia Died: 1 July 1971, Ipswich, United Kingdom (William) Lawrence Bragg was born in Adelaide in Australia, where his father (Wiliam Henry Bragg) was a professor at Adelaide University. When Bragg was 19, the family moved to Great Britain, where he studied at Cambridge. He carried out his Nobel Prize-awarded work when he was only 23, partly in collaboration with his father.
