2019/06/23 Hiking from Wuppertal to Solingen!

Another long weekend came. It comes always whenever I don't really need one. That's because now the new project started and I'm enjoying doing something, that I truly understand. Here's the short story of what was the problem in the last project and why the next one is going to be so good: In metals, there are different kinds of interactions, like electronic, elastic, magnetic and so on. The material I treated was mainly a composite of iron and manganese. And here, the most prominent effect comes from magnetism.

Here's the problem: I don't understand anything about magnetism. It's really a funny thing to say, because in theoretical physics we are essentially controlling everything in simulations. So all the phenomena happening in simulations must come from something integrated in the algorithm. But here I am, I still don't understand what this magnetism is, let alone what actually happens in the real world.

Growing mushrooms with coffee grounds

The story began at my 30th birthday. I got a mushroom kit as a present, which was just a box filled with straw. According to its instructions, I was just supposed to spray once or twice a day so that the mushrooms can simply come out from the box and they can be harvested at some point. The first one came out, but I somehow didn't really harvest it. It dried out very quickly. After removing it, nothing really came out, but I didn't really try to figure out what was the problem, probably because I knew that this mushroom kit was designed to be used once and not quite like plants where you can give water and nutrients and they grow forever.

Still my interest grew and I wanted to know if there was a possibility of growing mushrooms myself, also because before getting this mushroom kit, I knew essentially nothing about growing mushrooms, except for this one thing that what we call mushroom is the waste product of what the bacteria eat in the soil/wood/straw etc.
