On a day at the end of winter like today, one tends to pick up a bar of chocolate and chew it slowly in front of the TV. Then, when only the packaging is in the hand, one takes a closer look and realizes how many calories it contained: 560 kilocalories per 100 grams! As…
The carnival is here, children and adults are running around in costumes. I see wings on many carnival costumes. Butterfly and fairy are popular among little girls, boys perhaps more often dress up as pilots or Batman. Ever since we were children, we have had the desire to be able to fly, to go far,…
One of the most brilliant inventions of mankind is the bicycle. It uses muscle power in a very efficient way to move forward, it is much faster than walking, it is healthy, and even some load can be carried. I can’t wait to ride my bike in the spring sunshine. This passion of mine goes…
The next still free downloadable test version (Beta_05) of the DockCalc software has arrived. As I already wrote, the purpose of the program is to make it very easy for anyone to perform calculations with data for which a simple pocket calculator is no longer enough. Let’s face it, if our high school student child…
It’s a very strange question, I know, but I can explain it: My car has an average of 6.5 l/100km fuel consumption. When I typed this into my DockCalc program, the program immediately converted it to square meters (this is the strength of the software, that it understands the units of measure and helps to…
Electric cars – albeit more slowly than initially advocated by politicians – are slowly catching on in Germany. Although only a small percentage of the country’s car fleet is purely electric, more than a fifth of new cars registered in 2022 already have a purely electric powertrain. Many people are happy about this, since at…
I just received the latest summary on my heating costs. The paper states that my energy costs will from now more than double. In such cases, one is first scared, and then begins to think feverishly about what can be done. Of course, a colder apartment and showering cold are not as attractive as some…
Christmas is only a few days away, many people have already got a Christmas tree, some have already decorated it. I also prepared something for such a significant occasion: this time I won’t bother anyone with units of measure or physics, but instead I’ll just draw a Christmas tree – but in my own way,…
We know from history: Freedom is something worth fighting for, freedom is the word that has always been capitalized today and in the past. Anyway, when one is free he can do anything, go where he/she wants. This can apply to a free electron, for example – or not? Are free electrons really free? They…
These days, in the middle of November 2022 the population of Earth just reaches 8 000 000 000. For us humans, it is a nice round number having 9 zeros in it (having 10 fingers on our both hands, probably therefore using the base-10 (decimal) number system). Fun fact: sloths (3 fingers on one hand,…
