My place from his, is almost going backwards. NewPort to here. Coming in from the West. I can meet you out that way. I'm half certian Christian, could find a coffee for us both. Call me mid morning..

Regards The other Phil

I too can confirm that I will be there. It will be good to put faces to names.

Joe

Phils, no problem if you want to meet up at my place before hand.

In fact in two weeks time I'll be going to Turkey for exactly this.

Just an update on the science meetings I attended in Turkey.
67 countries, ~ 500 people, ~30 meetings ranging from 1 hour to two days. There was also a large (1000+ attendees) conference running at the same time but I was not involved with this.

The full decision on the confirmation of the proposed redefinitions of the fundamental scientific quantities has been put off until 2018.
This has enabled the group I am in to set up a project to further investigate the impact of the proposed changes - something we should have done earlier.
A subgroup I am involved with reviewed 54 scientific publications from the last 2 years and proposes to change the atomic weight of 19 elements. Mostly increased in the number of decimal places and smaller uncertainties, not significant for most practical situations but useful for some researchers. I can't say which elements as this will be part of a press release.

On the last two days there was a meeting of the overarching admin group with most of the ~250 people representing their country. It's sort of UN style- members sit grouped by country with the name of the country on each table. I was one of 4 in the Aussie delegation with the others being from Canberra, Sydney and Brisbane.

Australia was up against Brazil for hosting the 2017 Meet/conference. The presentation was given by the President of the Royal Australian Chemical Society and although the Aussies gave a superior presentation, because Australia hosted the meeting in Brisbane in 2001 and South America has never hosted, the Brazilians won easily. One of the scandinavians came up to me afterwards and good humouredly said "Another Gallipoli for Australia!"
As I have been involved on a voluntary basis indirectly for 11 years and directly for 10 years I reckon I have served my time and am well and truly ready to hang up my boots.

I managed to get a couple of days off in between meetings and there are a few travel snaps here

Unable to attend due to unexpected medical appointment.

Very, very sorry for such late notice.

Yebbut, what if the elements gorge themselves between now and 2018 - and put on weight?

As I saw on a T shirt -
"You can't trust Atoms - they make up everything"

It was a great day. I would recommend it to anyone if the opportunity arises again. It was also good to finally meet the people behind the names on the forum.

Thank you Roger for organising it.

Joe

A few photos of the guys attending today and some of the great gear we saw.
A brilliant afternoon! Thank you very much again for inviting us Roger!

Cheers,

Plus 1 from me as well Roger,please convey thanks to Andrew too.Utterly fascinating and a justifiable use of our taxes.The quest for ''nanonism'' goes on.enjoyed every minute of the tour.Huge thanks and am sure all attendees yesterday have gone home very much enlightened.John.

Any chance of letting us know who's who in the photos? I know Phil " Machtool" but I grind to a halt beyond that. It is a great thing to be able to put a face to a name.

Bob.

I can just make out Handlebar Phil (leaning over the counter) in the shot too, but that is all. It sure is good to put a face to the name.

Yes, I can make out Phil H also. Sorry Phil.
