Physicus mean
And whoever says nerd must also say fantasy. What sounds like a cliché tends to be true very often. Not very practical, but it works and is entertaining.Ĭomputer scientists are not only playful but often also nerds. Here you can’t even recognise the words Hello or World. “Hello World!” looks like this in Brainfuck: “You have to start the program with #include and then add this and that here…”. At some point, one of my fellow students took pity on me and helped me. I stared at the keyboard and didn’t know where to start. This was my first contact with programming at that time and it all still seemed like magic to me. Sounds simple? Boring? Useless? Every programming novice would probably disagree here! I still remember my first task at the lecture about the programming language C++: Program “Hello World!”. Because the first task for learning any programming language is: Get your program to output the text “Hello World!” on the screen. In my field, there is probably no one who has not at one time or another racked their brains over this. But as a theoretical physicist, I live at the intersection of physics, math, and computer science, and since it fits so nicely, that will have to do.īut not so fast, what does welcoming the world have to do with computer science? “Hello World” is more than just a slightly melodramatic greeting. What better words to start a blog about physics than these? Ok, granted, “Hello World!” comes more from computer science.
