Particle Physics Masterclass (MC), idea from UKStudents (16-18 year olds) spend 1 day at research institutelisten to lectures (introduction to particle physics)work like real scientists: Exercises with real data

European EPOG event for WYP 2005One or more MCs in each country (20 to 80 students per day)About 60 institutes from 18 countries participatingabout 3000 students participating (incl. 500 at RAL)Whole activity w/in 2 weeks: March 7 to March 19, 2005~ 6 masterclasses joined in video conference at the end of the day

Discuss results and differencesCombine results (better accuracy)questions to scientists

THANKS to

all contributing institutes (impressive work!)

Christian Helzel for putting all together

Schedule:58 institutes from 18 countries evenly distributed on 12 datesworked very well, (thanks to German Science-on-Stage office)

Example Lectures:proved useful for „newcomers“

happy to still add *your* talk on „wyp“ web page

Video ConferencesVideo Conferences

Technical PreparationTechnical Preparation

Tool used: VRVS (www.vrvs.org)browser based, just needs PC (windows or LINUX(?)) and Webcam

easy to include existing H.323 video conference systems

possible to share one desktop with all participants

Preparationsinstructions on www.vrvs.org and http://wyp.teilchenphysik.org

continuous support from Slovak group of CALTECH VRVS team

indispensible central support from CERN (Mick Draper, Joao Fernandes)

TEST I: 17.-19.1.: all 58 institutes, full 3-day test row in groups of 6.

7.+11.+16.2.: second try for 8 institutes

Technical Issues: many institutes tried VRVS for the first time

absolutely crucial to test with *real* equipment

main issues: audio (microphones, echoes), firewalls, …

Web pages and CDWeb pages and CD

Institute Pages:European wide collection of institute descriptions

very useful for local outreach

most difficult part to obtain completely, most difficult part to obtain completely, finally successful

National Links:invitation to further reading

Imprint:introduces and stresses EPOG role

Physics:much more than just masterclass exercises

•What are the fundamental building blocks of matter? •How can I identify them? •Which forces hold them together? •How do these forces work? •How far have forces and matter been understood? Find the answers to these and other questions by browsing, reading, and working through the Web systems collected on this CDrom in 16 languages. Most of the material contains interactive elements, some even real particle physics events for making your own measurements. System requirements: Web Browser, Java, Shockwave and Media Player

Marvellous Job by moderators: Silvia Schuh and Dave Barney

Good to have a LEP scientist on Board at CERN each day:Pippa Wells‚ Mike Lamont, Michael Hauschild, Frederic Teubert,

Richard Jacobsson, Alain Blondel‚ Tatsuo Kawamoto learning curve in technical and moderation issues

one institute with bad audio spoils whole conference

shared desktop becoming reliable after initial problems

moderation increasingly efficient

1.5h still (too?) long after a 7h long day?less institutes/day?

keep students awake! (competition?)

Still, students liked the ideahaving fun, reporting results, asking questions

liked contact to other sites

English language no (big) obstacle

Some citationsSome citationsThe quality of the video link was absolutely desastrous (Bonn I)

The video linkup had good quality and good interaction between universities (Bonn II)

The technical quality of the video link was far from excellent (Bonn II)

The video linkup was better than expected and had a high entertainment value (BonnII)

I learned a new method of scientific work and that I could apply this myself in the I learned a new method of scientific work and that I could apply this myself in the exercises (Bonn II)exercises (Bonn II)

The exercises were fun. The tutors were friendly and helpful (Bonn II)

I liked that the data came from a renowned institute and have an relation to real research (MK), but the exercise was too easy/boring (Bonn II)

The lectures assumed that we never heard the term „physics“ before….. which prohibited dealing with complex themes (Bonn II)

The lectures were complicated, lacking to explain basic knowledge (Bonn II)

It was „cool“ to compare our own results with those from other countries and other It was „cool“ to compare our own results with those from other countries and other experiments (Bonn II)experiments (Bonn II)

Very interesting to ask scientists from CERN, tried to answer every question, really goodGot the feeling that I do sth. which physicists do every day in their experiments,Got the feeling that I do sth. which physicists do every day in their experiments,

I felt involvedI felt involvedThe Lectures were very interesting, the exercises much fun, the scientists and the tutors very friendly, I learned very much

I liked the idea of contacting other pupils and discussing our results. It is sad that the technology is not perfectly developed (Berlin)liked, that video linkup was something new w.r.t normal schoolworkinteresting to learn how physical information is exchanged around the globeinteresting to learn how physical information is exchanged around the globe

The exercises were too easy, after 2 min You understand it, and then it was boring (Bonn II)exercises a bit difficult to understand, but very much and good help, (Berlin)

I liked the funny guys at CERN (Berlin)enough and good foodAll was great!!!

Thanks!Thanks!

To all of You making this event a success!

Should we continue?

How?

(including video linkup?, personpower? finances?)

When?
