As a person who never used any of the major social networks, I’m probably the wrong one to judge them. It has been done to death anyway. Mind you, I am not a total privacy freak either – I enjoy communicating online, especially in emails, forums and blogs. Then where does my aversion to the big social networks come from? After all, forums were (are) also notorious for toxic discussions, off-topic banters and proliferation of junk content.

Recently I submitted and defended my Master's thesis in physics. It was a glorious moment and you should feel bad you missed it.

Minimalism has fallen victim to hype, like many other concepts. A term like this has an origin and a niche following, then it becomes trendy. More and more people have their spin on it and want to label themselves as such.

This note is for people who know me and wanna see what I’m up to, and/or for anyone interested in German physicists’ culture of going to group trips. Feel free to skip it otherwise.

A realisation hit me as I opened my text editor to write some lines. There’s a peculiar breed of communication which proves greatly satisfying for certain people. I’d call it “interface communication”.

In Spanish, the verb convivir broadly means "to live together". A more nuanced translation could be "to live together in harmony" or even "to coexist". As most people, I've had my fair share of convivir.

Greetings! I am proud to present our brand new labs at the Institute of Optical Materials and Technologies! After a whole year of construction work, repairs and various emotions, the renovated labs are finally ready for action. And for our (many…) readers exclusively, I will present our optical arsenal.

Some time in 2015 I had this vision for an enlaserment website, where I would organise and present my freshly acquired knowledge on lasers. Now, that wasn’t a bad idea per se, but evidently I wasn’t equal to the task yet.

Today in the lab of atomic spectra we built a setup for observing the hyperfine structure of cesium. It is a big deal for atomic clocks as they use this transition to “tick”. It is also a very very tiny and fine effect (as its name suggests) so it’s pretty exciting that we can see it with such simple setup.

Finally… I am done with my exams and there is time for some fun.
No, I didn’t spend a fortune in a casino. But I wanted to try some of the “games” that could be assembled with my Conrad kit which includes a breadboard and some basic elements. The binary die caught my eye (woah, a rhyme!) Most tabletop games require a die or two. It’s usually a plain old six-sided guy, although if you’ve played Dungeons & Dragons, you know there are some bizarre looking cousins of this die. The most famous being the d20, or a regular icosahedron if you prefer the geometric term. So there I was, dreaming of how spectacular it would be if I appeared at our next D&D session with a light show on a breadboard which is actually a 20-sided die.

I guess no one says “laser rays” in English, but in Bulgarian the two words for ray (infinitely narrow) and beam (as a shaft or bundle) of light are frequently interchanged. This purely linguistic difference could actually teach us a bit how divergence works.

An optical fiber is essentially a waveguide for light. It consists of core and cladding and the refractive index of the core is larger than the refractive index of the cladding. Thus the light is confined inside the core due to total internal reflection. This simple concept can be observed here:
You surely have heard the quote misattributed to Einstein about explaining scientific ideas. It varies in wording but the message is the same: if you can’t explain it in a simple way, you don’t understand it well enough yourself.
