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 unsettling, but also...

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 was pulling him. Th...

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 form of communicati...

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 sense. But if we are...

Life is constant change or continuous change or everything in a state of flux - and whatever the phrases are called. The fact is: very little stays the same. Not only is this world subject to time and therefore to decay, but the process of change is sometimes very actively pursued and is even decisive here and there, sometimes even life-saving. However, change is not easy for everyone. For some pe...

Asparagus is only available for a short time each year. Unlike many other natural products that are available almost all year round, albeit often imported from far away, asparagus is only available here in spring. The harvesting work is time-consuming and, as far as I know, cannot be done by machine. Unfortunately, the asparagus is harvested by cheap labour imported from Eastern Europe. This manua...

There is a salt shaker on many tables. At least in the restaurants. It is used to add salt to the food. Salt has the effect of enhancing flavour. If you use the salt shaker, there should be a good match between the size of the salt grains and the holes in the shaker. Otherwise, it can either result in no salt escaping - if the grains are too coarse - or too much salt escaping if the holes are too...

We all know from our own experience that life is not always on the sunny side. There are good times, but there are also less pleasant times and sometimes life can be really tough and challenging. We often perceive circumstances as problematic and challenging and secretly or non-verbally it is the circumstances, the things we cannot influence, that we blame for such difficult phases. We are the vic...

The German term heilig probably goes back to the Old High German word heilag and originally had the meaning of "own" or "property". In certain translations of the Bible, the term "set apart for God" is also used. Holy is therefore something that is set apart for God, set apart for his ownership. This makes sense if you imagine that saints are people who have placed th...

Over the course of time, man has controlled surface waters, particularly in urban areas, by means of structural measures. For example, canals have been used to control the course of rivers. This makes the remaining land easier to plan and utilise - whether for housing or agricultural land. This is an optimisation that would not be possible if nature were left untouched. This works well as long as...

In pressure cookers and probably other cooking utensils, there are inserts that prevent the food from lying directly on the base of the pan. This ensures that there is no or much less burnt food or the inserts are used to ensure that the food is not directly or only barely in the water and can therefore be steamed by the rising water vapour. The inserts are easy to insert - but they can only be re...

When I was a teenager, the little bottles of fruit juice from a particular brand were all the rage. They came in many different flavours with different fruits and fruit combinations. You gave the bottles a good shake, then twisted the cap and there was this "click" sound that was unique to the product. This happened because there was a slight vacuum in the bottle and when you turned the...

Time is one of the most precious commodities, especially in our industrialised world. In production, for example, shift work is carried out in order to minimise unused time. We organise ourselves in such a way that we often pack as much as possible into a day or a week, and even on holiday we try to see or experience as much as possible - in other words, to maximise the density of experiences per...

A fuse is the part of an explosive device that is first brought into contact with the part that sets the fire. It then leads this fire to the explosive and causes it to explode. The fuse must be dry and can be of any length. The fuse allows the detonator to ignite the explosive device without it exploding immediately. There is therefore a time delay between setting the fuse on fire and explosion....

You have probably seen pictures in which a cone of debris was visible that was created by a landslide or an avalanche. Enormous amounts of material are set in motion and then stop at some point. At best, they leave no damage other than changes to the landscape; at worst, they cause great destruction and claim human lives. As far as I know, it is only possible to estimate in advance where this mass...

In German, we talk about something being annoying. And this term obviously contains the word "nerve". A nerve reacts to a stimulus. If we touch something with our skin, it reacts thanks to the nerves - and protects us from burns, for example, if we touch something that is very hot: we withdraw our hand very quickly and thus avoid worse skin damage. If something annoys us, it may be becau...

When the air pressure changes, this has a direct effect on temperatures. I didn't realise that a high-pressure area has so much influence that its higher pressure compresses the air to such an extent that it causes temperatures to rise. I hardly notice the increased air pressure, but I do notice the higher - or in the case of a low pressure area - lower temperatures. So if I just look at the t...

I'm a city kid and therefore not familiar with everyday agricultural matters. But I imagine that when sowing different plants, the farmer doesn't ask himself what they will grow into, but knows that this grain or this seed will become this or that and nothing else. The layman cannot see this in the seed - but the seed contains everything it needs to become a particular plant. I believe tha...

In our western world, the law is often represented by Justicia, who holds a pair of scales in her hand and is blindfolded so as not to be biased in her judgement. The scales used have two scales. Only when both scales are equally weighted is there balance, in this case justice. It is obviously about weighing up all the relevant factors - or to put it more subjectively: everything that has weight a...

I recently went out to eat and ordered a Vegi Dürüm at a place where I've never eaten before. As a dürüm is rolled up in a pastry bag, you can't see what's inside from the outside. I cut the dürüm open because I was sharing it with my dining partner. When I saw what was inside, I was shocked. It looked like meat and because the waitress hardly spoke any German, I assumed she had brough...

As the saying goes, where there's smoke, there's fire. But you can't recognise the fuel by the smoke alone. It could be a campfire with a lot of damp wood or a pneu factory that produces a lot of toxic fumes during a fire. From a distance, this can only partly be correctly interpreted from the colour of the smoke. The closer you get, the clearer it becomes - and most clearly when you a...

Board games usually use simple game pieces, each of which is assigned to a player. They are often made of wood, very simple and differ in colour from the other pieces. The pieces are then moved around the board by the corresponding player. If the game is not purely a game of chance, the player moves his piece according to certain strategic considerations. The piece therefore represents the player...

We recognise people not only by their appearance, but also by their voice or gait, etc. Where do these abilities come from? It is not the mind alone, but also the spirit, the quasi-supernatural, i.e. not rational. I believe it comes from what is beyond us. It is a creative gift that can be trained - but this rarely happens consciously. For example, we can become better and better at recognising wh...

Light illuminates and gives all sighted people the information they need to move around safely. It illuminates, brightens and helps us to orientate ourselves. Without light, in the dark, nothing changes in our surroundings - but we are no longer able to take safe steps in the same way. However, light also has the property that above a certain intensity it is harmful to our eyes and can dazzle us t...

Assuming you see an earthworm, i.e. an animal without feet, you might wonder how it moves. It actually works by contracting along its length and therefore straightening up in the middle, pulling the rear part towards the front while the front part remains stationary and then the rear part remains stationary and the front part pushes itself forwards. This sequence of movements is repeated continuou...
