ONLINE NBI foredrag om fysik for gymnasieelever

De nedenstående foredrag, som forskere fra Niels Bohr Institutet har afholdt i maj og juni 2020 som tilbud til hjemmearbejdende gymnasieelever og -lærere er afsluttet i denne omgang. Foredragene er ikke optaget, da det ikke ville være muligt pga GDPR regler. Ved titlerne ligger der links til slides eller hjemmeøvelser, som man frit kan anvende i undervisningen.

Charles Marcus Causality and Quantum (engelsk)

Homework problems for after the talk:

i) Where in your everyday life do the effects of relativity appear?
ii) Do slow clocks let me go on a space voyage at high speed and come back and meet my great great great grand daughter?
iii) How did Einstein get from the two postulates to E = mc2?
iv) Two things make special relativity “special”: no acceleration, and no gravity.
v) Where in your everyday life do the effects of quantum mechanics appear.
vi) Where in your everyday life do the effects of quantum entanglement appear.

Jason Koskinen Chasing the ghost particle at the South Pole (engelsk)

Soon after the discovery of the neutrino in 1956, the idea emerged that it represented an excellent astronomical messenger. Neutrinos are elementary particles with tiny (and yet unknown) mass and no electric charge. They interact only weakly with matter and can therefore escape dense astrophysical environments and cross vast cosmic distances without being absorbed or scattered. Not only are they potential messengers about some of the most exotic phenomena in our Universe, but the neutrino is also a portal to understanding fundamental particle physics at the smallest of physical scales. Presently, the most sensitive high-energy neutrino observatory is the IceCube experiment located at the South Pole. In our presentation, we will introduce the detector, highlight recent discoveries and summarize the research in neutrino astronomy and particle physics

Rajika Kuruwita/Georgy Makhatadze Our solar system and its weird cousins (engelsk)

Are we unique? Or can solar systems like ours form easily? - and would that mean life can exist just as easily? We look at our own solar system and discover the diversity of worlds in it. We then look at evidence we have, such as meteorites from the Moon, Mars, and young planets, and discuss what it says about how our sun and planets form. Then we look at how other stars are forming and what other solar systems look like. We try to answer questions about: Is our solar system unique? What do observations of other solar systems say about our own system? How well does our theory of solar system formation work for all the different types of planets discovered?

Oleg Ruchaisky New Particles: Do they exist and where can we find them? (engelsk)

Particle physics has a model, that describes all known particles and interactions. This model is so successful that it has been named "The Standard Model of elementary particle". Given this great success - why do scientists continue to search for new particles? What makes them believe that such new particles exist?

I will walk you through the current landscape of ideas, beliefs and expectations to give you a flavor of what are  these tens thousands of particle physicists doing?

Fysik med jord, luft, ild og vand = geofysik

Geofysik, eller jordens fysik, handler om at forstå jorden som dynamisk planet, lige fra langsomme processer som pladetektonik til hurtige processer som vejr og nordlys. Alle processer er med til at forme vore livsbetingelser, og i denne tid er der stort fokus på klimaændringer. Klimaet er formet af astronomi, kontinenter, have, atmosfæren og livet selv. Jeg vil snakke om noget af den geofysik vi arbejder med på NBI og om hvor svært det er at lave eksperimenter når man selv sidder midt i eksperimentet.
