I sleep and I dream.
There is a table in front of me, two bottles of beer on the table. But you can’t just drink it, because beer is a vector value, you have to take the projection on the axis. Next to the households are two cups of beer, from which you can drink, but the projection is taken on an arbitrary axis, unknown to me. Not the matter. You can project beer on the X-axis - pour it into a cup, but there is no third cup. You can re-project beer from circles to a known axis, but this seems to be time-consuming. Not the matter. I stand and think what to do.
For the time being, I think, a man breaks into the room and drinks beer from the first cup. And I’m crushing — to drink a beer taken in projection on an arbitrary unknown axis — it’s like roasting petroleum!
I wake up. There are about 18 hours left for the theoretical mechanics exam.
