  • 22.09. - How many calories does a black hole have?
    I think it's worth it to look at the little phenomena sometimes, to find the wow moments in everyday life and to ask yourself silly questions sometimes. You guessed it: The other day I had such a stupid question in my head. I was sitting in a café eating an excellent chocolate tartlet. The logical thought that came to me as I ate was: what is the food with the most calories? Does that even exist?
  • 10.06. - Academic self-defence – the disputation
    It's over! Six months after submitting my doctoral thesis, 5 years after starting my doctorate, 10.5 years after my first day at university - doctor rerum naturalium! The end boss is defeated, the disputation is over! And of course, I want to share with you what this defence is all about, how I prepared for it and also how disputations can differ from one another.
  • 08.03. - #BreakTheBias – Women can do physics
    It's 8th of March and that means: it's International Women's Day! In Berlin, it's even a public holiday! This year's motto is #BreakTheBias - for a world free of stereotypes, prejudice and discrimination. As a woman in physics, you can be sure that I can say something about this subject. Today, I don't want to feed you too many numbers (there are plenty on the web), but rather tell you about my own personal experiences.
  • 22.02. - The Stern-Gerlach Experiment – A history of stubbornness
    Even scientists are only human. That's why success stories often read like a comic book: great heroes fighting for the good of humanity. From another perspective, however, it sometimes seems more like the nagging of old white men arguing over who is right. We have already seen a few examples of this: Boltzmann and Planck fighting over entropy, Thomson and Rutherford decoding the atom, Newton and the rest of the world racking their brains over the nature of light. And the Stern-Gerlach experiment, which celebrated its hundredth anniversary this month and which is a milestone of quantum physics, was ultimately the invention of a scientist who desperately wanted to be right.
  • 31.01. - Schrödinger’s Tardigrade
    Polar ice, the moon, the quantum world - what do these places have in common? There is no Wi-Fi? Possibly. It's uncomfortable? Probably. They are uninhabited? Not at all! All these places have (allegedly) already been seen by a certain living being. Sometimes by choice, sometimes by design, sometimes by accident. What kind of creature is it that hangs around in such exotic, hostile places? It is small, chubby and it's name: Tardigrade! In 2014, tardigrades were found in the Arctic that had been "hibernating" for over 30 years. Since a crash landing of an Israeli space probe in 2019, a few tardigrades have been lying on the moon. And according to a group of researchers, tardigrades have now also made the leap into the quantum world! But is that really true?
  • 23.12. - Superluminal Elf Radio
    Santa's gift tour is a headache for children every year: How does he manage to visit every child in the world in a single night? But Santa's travel speed is not the only problem. I wonder: how does he know if the child whose chimney, balcony or front door he is standing in front of has been naughty or nice? Does he carry around the naughty-nice-list in paper form? Is he in radio contact with the North Pole? Or does he have a completely different method? We will ask the question: Is communication faster than the speed of light possible?
  • 30.11. - Science Slam – Battle of the Nerds
    I am the German Vice-Champion in Science Slam 2021! I'm really happy and think this is a great opportunity to take you with me into the world of the Science Slam. Hopefully, I can answer some of the most frequently asked questions about Science Slam and maybe I can motivate some of you to venture on stage and share your hard-earned research with the world.
  • 29.10. - A whiff of stress – the doctoral thesis
    It's been a bit quiet on my blog for the last few months, but finally I have some good news: my thesis is finished! Yippee yay, it's done! Today I want to review the process with you, tell you about my experiences, think a bit outside the box and tell you why it's not over yet.
  • 30.08. - From Physicus Minimus to Physicus Maximus
    Facebook surprised me this week with a reminder: seven years ago, I submitted my Bachelor's thesis. Seven years - time flies! And almost exactly seven years later, I'll be handing in my doctoral thesis. I'm in the absolute final sprint right now (keep your fingers crossed for me). I thought this would be the perfect opportunity for a little review: What has changed in the last seven years? What was the path like from the Bachelor's degree, through the Master's, into the doctoral studies, (almost) all the way to the Ph.D.? Am I really smarter now than seven years ago?
  • 20.06. - Doctor-What? Career fair with Dr. Doom, Dr. No and Co.
    My PhD is slowly coming to an end and I thought this is the perfect time to take you to the heart of the matter. In my series "How to PhD", I would like to show you different aspects of my life as a physics PhD student, and today I'm getting down to the nitty-gritty: What exactly does it mean to do a PhD? What exactly do I have to do to get it? And also in the context of the current #IchBinHanna debate in Germany: Is this all above board?
  • 13.05. - FAQ: Quantum Computer
    Everyone is talking about quantum computers. Do you sometimes feel like you've missed the boat and no longer dare to ask how a quantum computer actually works and what it's supposed to be good for? Then my blog series "FAQ: Quantum Computer" is for you! Many news articles on quantum computing do not (or no longer) go into sufficient detail about the new quantum machines, which quickly leads to misunderstandings and confusion. I have gone into the details of the "miracle machines" in three articles. Here you will find an overview of the questions I have tried to answer - including a short version of the answer.
  • 25.04. - FAQ: Quantum Computer – From classical to quantum computer
    The quantum computer as the holy grail: with it everything will be better, everything will be faster, unsolvable problems will become child's play, banks beware - your encryption is finished! Is that really the case? In what are quantum computers really better than classical computers and in what are they perhaps not? In my series "FAQ: Quantum Computers" series, I try to clear up common misconceptions and erase question marks. This is the last part of the series and it's about the differences between classical and quantum computers.
  • 14.03. - FAQ: Quantum Computer – From Qubit to Quantum Computer
    Many articles on quantum computing are rushing quite a lot. "A qubit can be in the states 0 and 1 at the same time, and that's why quantum computers are better than classical ones." Sure…? Um, no, that was a bit too quick. In my series "FAQ: Quantum computer" I try to clear up common misconceptions and erase question marks. This article is about how to make a quantum computer out of many qubits.
  • 26.02. - FAQ: Quantum Computer – From Bit to Qubit
    Quantum computers bring quantum physics into the spotlight. Because tech giants as Google, IBM, Microsoft, and Amazon are all over them, they are the talk of the town. In addition to scientific journals, daily newspapers and gossip magazines also report on qubits and their friends. Quantum computers are always explained "simply and compactly". I could also write an article like this, but more specifically, I would like to address the misunderstandings and confusion that such articles often cause. This is not (necessarily) the fault of the authors because no one can adequately explain quantum physics in 5000 characters. Others, however, blatantly sell the quantum computer as a holy grail or Pandora's box. As so often, the truth lies somewhere in the between.
  • 22.08. - Quantum technology 2.0
    When you think of quantum technology, you think of quantum computers. Or science fiction, light sabres and half-dead cats. But quantum technology is more than the chase for the quantum computer. The second quantum revolution is about breaking boundaries and taming nature's smallest building blocks. What emerges is a superlative technology: smaller, faster, safer, more precise. And not to forget: more incomprehensible.
  • 31.07. - Quantum technology 1.0
    Quantum technology is on everyone's lips. Boulevard newspapers report on quantum computers under the factual title "Computers will dominate mankind!" In most cases, quantum technology is presented mysteriously, as a product of the future: science fiction. But one point most articles keep quiet about: Quantum technology already exists and we all have it at home.
  • 10.06. - Hobbits in Latex
    Today we are talking about latex. Flexible, adapts to any shape, but sometimes a bit uncomfortable, especially for beginners. If you don't think of black, tight-fitting clothes when you think of latex, you're definitely a nerd. We are talking about the word processing programme LaTeX - probably the most important and most widely used tool among scientists.
  • 31.05. - 5 ways to deal with flexible working hours
    In my series "How to PhD", I would like to present different aspects of the life of a PhD student, or more generally, a researcher. Who has not studied or done a PhD (yet) has usually little idea of how research actually works. I would like to change that in an entertaining way and in small servings! The focus of this article: flexible working hours.
  • 27.04. - The identity crisis of light
    Sometimes you have to make a choice. Some things you hate, for example, or you love them. Like Brussels sprouts, marzipan or Big Brother. In other cases, you have to take sides: Cats or dogs, Edward or Jacob, wave or particle. But as unlikely as it may sound, sometimes you can be two things at once. Although when this happens in the very foundations of physics, it can start heated discussions. Like at the beginning of the 20th century when Albert Einstein threw light into a deep identity crisis: wave or particle, which is it?
  • 21.03. - The two birthdays of quantum physics – Part 2: Einstein and the jumping spark
    Is Einstein the father of quantum physics? Although most people associate him with the theory of relativity, Einstein made significant contributions to the development of quantum physics. In fact, he received his Nobel Prize in 1921 not for the theory of relativity, but for his explanation of the photoelectric effect - one of the key experiments in quantum physics. And like many discoveries in physics, this one was pure chance.
  • 24.02. - The Two Birthdays of Quantum Physics – Part 1: Planck and the Measure of Chaos
    In my last article, I explained that, deep down, light consists of energy packets – quanta. These are created, for example, when light interacts with atoms, the building blocks of our world. That sounds very daring and raises many questions, some of them deeply philosophical. And while you are racking your brains about it, one question arises: Who actually thought this up?
  • 12.01. - What actually are these quanta?
    A quantum of happiness, a quantum leap in technology, Firefox Quantum. Quanta seem to be present in our lives: they have entered common speech, the newspapers are frequently reporting about quantum computers. Yet hardly anyone outside physics knows what quanta actually are.
  • 01.01. - Hello World!
    What better words to start a blog about physics than these? Ok, granted, "Hello World!" comes more from computer science. But as a theoretical physicist, I live at the intersection of physics, math, and computer science, and since it fits so nicely, that will have to do.
