The Society of Italian Researchers and Professionals in Western Canada (ARPICO) is hosting a physics event for those of us who don’t have Phd’s in physics. From an October 24, 2018 ARPICO announcement (received via email),
The second event of ARPICO’s fall 2018 activity will take place on Tuesday, November 13th, 2018 at the Roundhouse Community Centre (Room B). Our speaker will be Dr. Pietro Giampa, a physicist who recently joined the ranks of the TRIUMF laboratories [Canada’s particle accelerator centre and, formerly, Canada’s National Laboratory for Particle and Nuclear Physics] here in Vancouver. Dr. Giampa will give us an intriguing and, importantly, layperson-intelligible overview on the state of our knowledge of the universe especially in regards to so-called dark matter, a chapter of physics that the most complete theoretical model to-date cannot explain. We will learn, among other things, about an ambitious experiment (set up in a Canadian mine!) [emphasis mine] to detect neutrinos, fundamental and very elusive particles of our cosmos. You can read a summary of Pietro Giampa’s lecture as well as his short professional biography below.
We look forward to seeing everyone there.
The evening agenda is as follows:
- 6:30 pm – Doors Open for Registration
- 7:00 pm – Start of the evening event with introductions & lecture by Dr. Pietro Giampa
- ~8:15 pm – Q & A Period
- to follow – Mingling & Refreshments until about 9:30 pm

The Mysterious Dark-Side of the Universe: From Quarks to the Big Bang with Dark Matter
Understanding the true nature of our universe is one of the most fundamental quests of our society. The path of knowledge acquisition in that quest has led us to the hypothesis of “dark matter”, that is, a large proportion of the mass of the universe which appears invisible. In this lecture, with minimal technical language we will journey through the structure and evolution of the universe, from subatomic particles to the big bang, which gave rise to our universe, in an ultimate research to describe the dark side of the universe called dark matter. We will review what we have learnt thus far about dark matter, and get an in-depth look at how scientists are searching for something that can not be seen.
Dr. Pietro Giampa originally completed his undergraduate in physics at Royal Holloway University of London in the UK, where he wrote a thesis on SuperSymmetry Searches with the ATLAS Detector (so LHC related). Following his undergraduate, he completed a Master Degree in particle physics at the same institute where he developed a novel technique for directional detection of neutrons. It was after his master that he moved to Canada to complete his Ph.D at Queen’s University in Particle Astrophysics, working on the DEAP-3600 Experiment with Nobel laureate Prof. Arthur McDonald. In the summer of 2017 he moved to TRIUMF, where he is currently the Otto Hausser Fellow. At TRIUMF he continues his research for new forms of physics, by studying Dark Matter and Ultra-Cold Neutrons.
WHEN: Tuesday, November 13th, 2018 at 7:00pm (doors open at 6:30pm)
WHERE: Roundhouse Community Centre, Room B – 181 Roundhouse Mews, Vancouver, BC, V6Z 2W3
Tickets are Needed
- Tickets are FREE, but all individuals are requested to obtain “free-admission” tickets on EventBrite site due to limited seating at the venue. Organizers need accurate registration numbers to manage wait lists and prepare name tags.
- All ARPICO events are 100% staffed by volunteer organizers and helpers, however, room rental, stationery, and guest refreshments are costs incurred and underwritten by members of ARPICO. Therefore to be fair, all audience participants are asked to donate to the best of their ability at the door or via EventBrite to “help” defray costs of the event.
- Where can I contact the organizer with any questions? firstname.lastname@example.org
- Do I have to bring my printed ticket to the event? No, you do not. Your name will be on our Registration List at the Check-in Desk.
- Is my registration/ticket transferrable? If you are unable to attend, another person may use your ticket. Please send us an email at email@example.com of this substitution to correct our audience Registration List and to prepare guest name tags.
- Can I update my registration information? Yes. If you have any questions, contact us at firstname.lastname@example.org
- I am having trouble using EventBrite and cannot reserve my ticket(s). Can someone at ARPICO help me with my ticket reservation? Of course, simply send your ticket request to us at email@example.com so we help you.
What are my transport/parking options?
- Bus/Train: The Canada Line Yaletown Skytrain station is a 1 minute walk from the Roundhouse Community Centre.
- Parking: Pay Parking is underground at the community centre. Access is available via Drake Street.
With regard to the Canadian mine and neutrino experiments, I hunted down a little more information (from an October 6, 2015 article by Kate Allen for thestar.com), Note: A link has been removed,
Canadian physicist Arthur B. McDonald has won the Nobel Prize for discoveries about the behaviour of a mysterious solar particle, teased from an experiment buried two kilometres below Sudbury [Ontario].
The Queen’s University professor emeritus was honoured for co-discovering that elusive particles known as neutrinos can change their identity — or “oscillate” — as they travel from the sun. It proved that neutrinos must have mass, a finding that upset the Standard Model of particle physics and opened new avenues for research into the fundamental properties of the universe.
McDonald, 72, shares the prize with Takaaki Kajita, whose Japanese collaboration made the same discovery with slightly different methods.
To measure solar neutrinos, McDonald and a 130-person international team built a massive detector in an operational copper mine southwest of Sudbury. …
To solve this problem, McDonald and his colleagues dreamt up SNO. Deep in an INCO mine (now owned by Vale), protected from cosmic radiation constantly bombarding the earth’s surface, the scientists installed a 12-metre-wide acrylic vessel filled with 1,000 tonnes of ultra-pure heavy water. The vessel was surrounded by a geodesic sphere equipped with 9,456 light sensors. The whole thing was sunk in a 34-metre-high cavity filled with regular water.
When neutrinos hit the heavy water, an event that occurred about 10 times a day, they emitted a flash of light, which researchers could analyze to measure the particles’ properties.
Allen’s article has more details for anyone who might want to read up on neutrinos. Regardless, I’m sure Dr.Giampa is fully prepared to guide the uninitiated into the mysteries of the universe as they pertain to dark matter, neutrinos, and ultra-cold neutrons.
