Take the 997 points collinear at coordinates x=1,3,⋯,1993. The midpoints are 2,3,4,⋯,1992.Take two points A and B which are the maximum distance apart. Now consider the following midpoints: M, the midpoint of AB, the midpoint of each AX for any other X in the set (n...
Without loss of generality, let points A and B be (0,0) and (0,10), since for any other combination of points, we can just rotate the plane to make them (0,0) and (0,10) under a new coordinate system. When we pick point C, we have to make sure that its y-coordinate is...
really are. I don’t think handheld gaming consoles have to be pocketable, necessarily, but I don’t to want to draw attention unnecessarily in public by pulling out a Steam Deck and gaming on the bus/train/plane. It’d be like taking an iMac to a Starbucks. Sure you can, but do ...

When I first got off the plane, the weather was still very cool. But most of the time I had to fake an umbrella and put on sunscreen to prevent my skin from getting sunburned. M: Did you do anything else? W...
Points are measured with an accuracy of about 15 μm in the bending plane. The geometric coverage extends down to angles of 9° from the beamline.Electromagnetic and hadron calorimetersThe ECAL employs dense lead tungstate scintillating crystals. Each crystal has a length of about 23 cm ...
