Let’s imagine that I am not a professor of computer science. I am instead a guide in the mountains of Wyoming.
Each of you has hired me to help you climb a mountain.
I can show you what to pack and how to pack.
I can talk to about the kind of weather you should expect. I know how quickly temperatures can drop. I have seen snow even in summer. Afternoon storms are common. I can warn you about the danger that lightning poses to hikers caught above the treeline.
I can tell you how long each trail is. I give you the measure of the distances in miles and hours. I can tell you how much elevation you will gain. How should we pace ourselves?
I point on the map to the stretches where a trail is steep. I mark the overlooks where you will find the best views. Here, I say, is where you will be most exposed to the weather and here is where you can find some shelter.
Even the most experienced and well-prepared hikers sometimes run into difficulties.
- What might go wrong?
- What should you do in those cases?
- When should you turn back?
You might have climbed other mountains in other parts of the country. These mountains might be different.
On the one hand, you might be younger and stronger than I am. On the other hand, I have been around for a long time. Maybe I know some stuff.
I will be at your side during this ascent. However, I cannot climb the mountain for you.
How will you make use of your guide? What advantage did you hope to gain by hiring me?
How is a professor like a mountain guide?
