And do you remember where you first heard the word algorithm? In what context, maybe? Algorithm. Was it at university? It could've been at university, many years ago. Well, while you were studying? I've an engineering degree, yeah. I see. That makes sense. Great, so that is everything. I just have a short survey of two pages. Okay. If you have time to fill that out would be great. Yeah, no worries. Thank you.
