After the long, warm summer came the cold, the morning temperature suddenly dropped to around freezing point. I’ve had plenty of sunshine for months, and now I’m suddenly really missing it. Today, my attention is focused on heating energy and as an engineer, my mind is already thinking about whether I could use some thermal…
Sounds like a strange question, doesn’t it? Well, obviously one, because the name horsepower includes “horse”! But that is not entirely the case. The horsepower unit dates back to James Watt’s time. When he developed his steam engine and wanted to rent it out to do the work of horses to drive the pumps or…
The matriculation exams are slowly coming to an end. It is hoped that the majority have successfully overcome the obstacles and will be able to enter life with a capital letter or continue their studies at a higher education institution. But it is certain that it is a huge relief to get over it and…
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.
