Even Bananas 11: How do we study neutrino oscillation?

The super bizarre quantum eraser experiment

The quantum eraser experiment is one of the weirdest phenomena that has ever been observed. It seems that quantum mechanics mixes past and future together. In this video, Fermilab’s Don Lincoln takes you through this quantum conundrum.

Even Bananas 10: How do neutrino oscillations work?

A woman with long brown hair holds three tricolor beach balls. To the left of her text that reads "neutrino oscillation."

Things get weird at the smallest scales — just take a look at the way neutrinos behave as they travel. In this episode, we’ll explore the phenomenon of neutrino oscillation through something a bit easier to grasp: beach balls. Join neutrino physicist Kirsty Duffy for some delightful quantum chaos.

Quantum mechanics and the double-slit experiment

Quantum mechanics is one of the most confusing fields of contemporary physics. Fermilab’s Don Lincoln introduces the big ideas and prepares the viewer for a follow-on video that is even more mind-blowing.

Emerging technologies: Quantum information science

Quantum information science is a key area of research at the DOE’s national labs. Scientists and engineers are working to develop quantum sensors and computers as well as quantum internet. Silvia Zorzetti talks about research at Fermilab’s SQMS Center.

Emerging technologies: Particle accelerator R&D

A particle beam is a very useful tool. It can diagnose a disease, destroy a tumor, improve a chip, clean up dirty drinking water, scan containers for suspicious content and do much more. Fermilab’s Sam Posen talks about accelerator research at Fermilab, a world leader in particle accelerator science and technology.

Even Bananas 09: A bunch of neutrino questions

A woman with long wavy brown hair wearing a black T-shirt holds a banana in one hand. She is in front of a turquoise gradient background with question marks on it. In the lower left corner is an illustration of a banana. Across the middle the text "Viewer Questions!"

Fermilab scientist Kirsty Duffy responds to some of the many wonderful questions viewers have left in the comments, including: Were neutrinos made in the early universe? How do you know you’re seeing neutrinos from your accelerator? And can neutrinos pass through a neutron star? Plus, a guest visit from fellow Fermilab science communicator Don Lincoln.

Amazing ways to look for dark matter

A man with short gray hair and glasses smiles. He is wearing a black blazer and a black T-shirt that reads "Physics is everything." He is in front of a starry sky. To his right, text that says "Can we find dark matter?" In the lower right-hand corner, an illustration of an atom.

Dark matter remains one of the unsolved mysteries of modern physics. In this video, Fermilab’s Don Lincoln explains two innovative methods whereby Fermilab scientists look for types of dark matter the broader community largely overlooks.

Even Bananas 08: The solar neutrino problem

A woman with a black shirt looks concerned and holds a banana in one hand. To the right of her, an illustration of a sun-like object that says "The Solar Neutrino Problem" in the middle of it. An illustration of three bananas is in the right-hand corner. Different flavors of neutrinos appear to come out of the sun-like object. Two electron neutrinos are in dark brown, other neutrinos are light in shade.

Throw on your shades: Today on #EvenBananas, we’re looking at particles from the sun — and how trillions of them went missing. Join Fermilab scientist Kirsty Duffy to explore how an experiment using 100,000 gallons of dry cleaning fluid a mile underground led to one of the biggest mysteries in particle physics: the solar neutrino problem.

Even Bananas 07: The 3 neutrino flavors

A still with "Neutrino Flavors" written across the top. The o in flavors is a neutrino. Underneath it, the other two neutrino flavors illustrated, and a circle with a photo of a woman with dark hair and a pink and black top. Under her, it says "With guest Valerie Higgins." A woman with long brown hair holds an ice cream cone on the right side of the still.

Grab your bibs — in today’s tasty episode, we’re digging into neutrino flavors. Join Fermilab scientist Kirsty Duffy and archivist Valerie Higgins to meet the three flavors of neutrinos and learn how to catch a neutrino with a DONUT.
