Second sketch, this time could you draw me how an algorithm works? Pff. Eh. How does it work? Yeah This is a completely abstract, mathematical thing. How can I record this? How can it be visualized? How could you visualize this? I have no idea. Maybe in the form of some generic formula or something You can do that. They can do whatever they want. I can't think of anything right now. I'm too far away from math. I wouldn't know what to draw now. What if you just drew an algorithm, not how it works, but what an algorithm is? Would you have any idea how to visualize that? No, um... Just a replacement symbol, a computer. Gladly, you can do that Yes to, I don't know... A calculator or something. Then these are keys. Voila And why would you draw this? So why would you take the calculator as a symbol for an algorithm? It's just that it might be most accessible to most people. I don't think most people know what an algorithm is. Let's wait a moment [short pause, because it's very loud] How do you know what an algorithm is? Uh, if I had to define it now, I'd have to go to the shallow end. That's just so far down the line, is that just... Uh... Well, actually a program code or mathematical formulas in a program code, which just do some calculations, compare data and so on Where did you get the information? So where did you learn about algorithms? I work in IT. Okay, yes, and they're just in touch. Is that where you first came in contact with it? In IT, you mean? Yeah, so through the job. Yes And in everyday life, do you sometimes have contact with algorithms somewhere? They're omnipresent, yes. I mean any machine that's smarter than a simple phone is basically based on algorithms. Yeah, well, that's the core of computer science. The intangible core of computer science. Yes, well... They're everywhere, so yes. And that's how you keep coming in contact with them. So you can't see them... You're not aware of yourself, yes. So they're abstract, immaterial. They don't communicate externally, so that's a bit autistic. Can you tell me the last time you think you interacted with an algorithm or you think there was an algorithm behind it. hmm. When I walked out of the office five minutes ago. Well, I work with computers, so I'm always around these things. Well, thank you very much.
