Your Friendly Physicist & other Nerds
According to the Internet, nerds spend inordinate amounts of time on unpopular and non-mainstream activities, which are generally highly abstract, or relating to topics of science fiction and fantasy. Well, isn't that the perfect description of a scientist?
I am in conversation with scientists that shape the world we live in today and tomorrow. We take a close look at trends in cutting edge technology, explain how the smallest things influence the big in physics and generally talk nerdy stuff. So stay tuned if you are a newbie to physics and interested to learn about the world of friendly scientists or if you are up for a PhD worthy nerd talk.

How to save a coral reef?
Coral reefs are important ecosystems and biodiversity hotspots. Many species of fish, invertebrates, and other organisms depend on coral reefs for their survival. 🐠 🦑 🦀 🐚
Sadly, more and more coral reefs die, due to warmer and more acidic oceans, overly destructive fishing methods, and plastic waste.
But there is also some good news: Many projects around the globe have the mission to regrow and restore coral reefs. Last week, I visited one of these projects - the Amun Ini Coral Reef Restoration Project, which is located in the Philippines. Together with the co-founder Bigs Eggert, I discussed how to regrow corals, what challenges this brings along, and why the Amun Ini project is not only important for the ocean but also for the local community here in the Philippines.

What are quantum dots?
Quantum dots! 🚀 🔬 👩🔬
This term was first coined by the physicist Mark Reed, and I think he did a pretty good job: with the buzzword 'quantum' it sounds super fancy, and still, no one really knows what it means.
Why is their size so important? Where do we find quantum dots in our everyday life? And why is Elon Musk quite happy quantum dots exist?
All of these questions I discus with Prof. Wei Chen from Shenzhen Technology University. Tune in for a fascinating journey into the land of quantum effects. Along the way, we will meet strange creatures like bandgaps, semiconductors, and perovskite crystals. But Wei is an excellent quantum dot scientist: After receiving his Bachelor's and Master's degrees from the Hubei University, Wei joined the Chair of Functional Materials at the Technical University of Munich. There he did his PhD on quantum dot-based materials. Currently, he runs the Energy & Photonics Lab (EPL) at Shenzhen Technology University and starts his own commercial, based on novel quantum dot technology.

Utilizing CO2 for a greener world
CO2 is everywhere!
In the atmosphere as well as in everybody's mind. So what, if we simply take it and transform it into something useful? Wouldn't that solve a lot of problems?
This is exactly the idea of the British start-up ViridiCO2 Ltd., which spun out from University of Southampton around 2.5 years ago. And just recently, I had the pleasure to sit down with their Senior development chemist Panashe Mhembere to talk about how this works!
🌍 How to utilize CO2 and turn it into something useful!
♻️ How ViridiCO2 contributes to a circular economy!
💪🏽 What main challenges this brings!
🤓 Why it is a good thing to follow your inner nerd!

How to destroy the universe?
False Vacuum Decay!
This term describes when a meta-stable quantum field (=False Vacuum) becomes a stable quantum field (=True Vacuum). This might happen at some time to the (maybe) meta-stable Higgs Field, and the consequences would be quite drastic: the annihilation of the entire universe ☠️😱
Kurzgesagt explained this concept already a couple of years ago, and recently, we turned their YouTube video into a 60s short video! (links are in the comments). Back then, I thought, no way, people would actually understand what we want to tell. But I it worked out great, and the final video highlights how powerful the combination of clear language and intuitive visuals can be.
And still, False Vacuum Decay is such an exciting and dreadful topic, it's easy to get lost in the rabbit hole. Luckily, we don't have to explore this rabbit hole on our own: Dr. Alessandro Zenesini, scientist at the INO-CNR National Institute of Optics in Italy, took the time to guide us.
Together we discuss the general concept of False Vacuum Decay, the consequences for us and the universe, why it might not necessarily be the end of the universe but also the start of a new one, how likely this scenario might happen, and why he is a big fan of kurzgesagt!
Thank you, Alessandro for being an excellent guide and a great podcast guest!
