About 'Bathtubphysics'
This is bathtubphysics.de - a site that will present physical and mathematical problems to you.
Most of the time, this is just for toying around. I am a German system engineer (i. e. I do IT) who just happens to have studied physics at RWTH Aachen University without making that my professional career. However, I still enjoy playing around with more or less weird physical setups or mathematical problems.
That is why I thought to myself: "Hey. Why don't you make a blog out of this stuff?". After all, some things I produce in my head might have educational value to someone else. The final push I needed came from 3blue1brown's #SoME2-challenge.
I highly recommend that you check out 3blue1brown's great Youtube channel. The animations are incredible and the topics are always interesting problems that are explained in a beautiful visual way.
So, to wrap this up, this is what I came to do. Chewing bubble gum and post lengthy calculations not many people will ever care about. And I just ran out of gum.
Why "bathtubphysics"?
Way back when I was a child and still had a bathtub at my disposal, I used to be fascinated by the water jet that came out of the tap. I noticed that its diameter was a bit larger right at the tap in contrast to the diameter a bit further down. Furthermore, this seemed to be a general phenomenon that could also be observed at the kitchen sink.
That was the very first moment in my life - as far as I recall - that I got hooked by a physics problem. I might have had questions about physics, earlier (like "Why does a mirror switch left and right but not up and down?"), but this is the oldest one in my memory that I really could not leave alone.
Since I still was in elementary school back then, I had to wait for quite a while before I could solve this one, but as an adolescent who could ask his physics teacher for some help, I finally managed to get a satisfying answer.
In the end, I consider this story to be somewhat of a beginning to my "career" as a physicist. You could say, all the madness around here started in a bathtub.
German imprint
The imprint for a site like this is a legal requirement in Germany. Therefore, I headed over to a German imprint generator and copied the result to this site.
Obviously, this is the reason why the imprint is in German while the rest of this site's content will be in English, so it can be of use to a wider audience.
The bottom line is, I do not intend to grab all your personal data. My server does log every access to this site for debugging purposes, as is routine. So I will store your IP address and what site you requested, but I will never look into this for any other reason than investigating a technical error with this site or my server.
At the time, I do not plan to monetize this project, which might change in the future. (Assuming there will be anything to monetize, that is. And I highly doubt this will ever happen.)
Anyways, that is what I had to say before I could start blogging - which I will have to postpone further, as I am curently sitting next to a canal taking a break from my hike of the day. Unfortunately though, I will have to get moving again, or the restaurant at my destination will have closed and I will have to still be hungry when I go to bed. (Which would be very sad...)
