They say 'hard shell, soft centre'. The image of the nut is used here. To open the nut, a nutcracker is used, for example, which transfers the force to the shell and cracks it so that the kernel of the nut becomes accessible. The shell often splinters in the process and the kernel is also damaged by the violent opening. This is the force variant. However, there are also su

Food storage boxes keep food fresh. However, they also need the right environment. So what needs to be stored in the fridge also belongs in a food storage box in the fridge and what does not, does not. Some boxes can be sealed airtight, others are more open. Some are light-proof because this is better for storing certain foods, while others are transparent and allow an overview of

In forests or free-standing trees, the weather side can often be recognised by the heavier moss growth or greenish discolouration of these trees. The weather side is the side of an outdoor object - which can also be a building - that is mainly exposed to wind and precipitation, i.e. the weather. So on the one hand, the weather leaves traces and on the other hand, the objects absor

Not so long ago there was this provocative slogan "Stinginess is cool" and many people meant it not just ironically, but seriously. Financial optimisation, as much yield or return as possible for as little investment as possible. In the western world, we can afford such ideas or approaches. In many areas, we are in a better position than the poor. But this actually means

Old bunkers often have small hatches. These were used to give the soldiers in the bunker the greatest possible ability to react to the outside with the smallest possible attack surface and the opportunity to get a visual impression of the situation outside. It is only a very small area in which the defence can be attacked and, as mentioned, in addition to the field of fire to the

To send a letter, you must affix a stamp to the envelope. If this is not done, the letter may be sent, but you will subsequently receive a request for payment. The stamp is therefore a kind of credit system: I buy a certain amount beforehand and can spend it and send letters as long as this credit is still available. Today, we often live the other way round: we first spend money t

It's amazing and even frightening what artificial intelligence can do today. Images can be artificially generated that are almost indistinguishable from the real thing. This poses a massive threat to the trustworthiness of information. More and more often, the question arises: is what I am seeing, hearing or reading true? How can I be sure that it is? This can not only be unse

To make progress on your bike, you need a few basic components that work well together. This includes the bicycle chain. If this is not well adjusted or is old or otherwise limited in its function, it can be a hassle. I experienced how a colleague's chain broke on a bike tour. We were somewhere in the middle of the countryside. He had no choice but to hold on to someone who wa

Every now and then I am woken up in the morning by the birds and their chirping. It's nicer than being woken up by a construction machine. But what I have noticed is that the chirping is totally mixed up. I had the impression that none of the birds were listening to each other, they were all chattering wildly and without interruption. Why do they do that? Is birdsong also a fo

We know many different balls: There are footballs, handballs, medicine balls, basketball balls, floorball balls, baseball balls and probably many more. I learnt that you can't play football with volleyballs because they suffer badly. And nobody would probably play basketball with a medicine ball because it's so heavy. Each ball for its own purpose or sport. That makes sens
