Cosmological Horizon

Monday morning.  I am leaving my flat. I am a little bit late and will have to attend an important meeting at work. I am trying to get the bus. Just as I reach the bus, the bus driver makes eye contact with me and closes the door right before my face. Damn it! I get on the bus right after that. Of course, we are stuck in traffic. I am not in time for the meeting and get in trouble with my superior. I somehow make it through the day but get into a fight with my girlfriend over some small, unimportant thing.…

Things particle physics and Formula 1 racing have in common

Twenty-five minutes northwest of downtown Geneva lies the Large Car Collider (LCC). At the LCC, cars travel at very high speeds in a 352m circular orbit, intersecting paths at 5 main collision points. In each collision event, the energy of the cars involved is large enough to generate up to four different insurance claims per event. …

Moore’s Law and the potential of polymers in nanotechnology

Everything in our modern world relies on computers, be it for your personal entertainment or the stock exchange, from simple accounting to the regulation of national power grids. You yourself are probably carrying a computer with you right now in form of your smartphone, which is, simply put, nothing more than a sophisticated calculator. The increasing computerization and its benefits are the results of over half a century of intense research and improvements in the fields of semiconductor physics and computer sciences.…

Can I fry a Schnitzel using a terawatt laser?
and how long does it take?

Multiterawatt lasers can indeed supply radiation with a power that equals a dozen nuclear power plants – combined! But can we abuse this technology to quickly warm up food? Can I heat up some eggs without instantly pulverizing them? Could I use such a laser to achieve a nice crust on my crème brûlée? And how long does it take?…

PhD life and deadlines…

Sometimes PhD students have to do things that they don’t want to do. For example, writing this blog on Friday evening. Writing about science should be fun, but here I am writing reluctantly on the last day before the submission. Sitting in my office reading papers about Auger electron spectroscopy and trying to filter beamtime data at the same time. Also listening to lofi music to keep calm. A lot is going on in my ‘PhD life’ and personal life at the moment. From stressful things like flight cancellations and manuscript revision to rather fun things like dance classes and new data analysis codes. …
