When measuring a speed, the most common way to calculate it is by recording
how far something went and the time it took to go that far. In the case of light,
this is very difficult. One could conceivably shine a light over a vast distance
and have someone else record when they see the light, but this would be difficult
even at large distances. The person recording when they see it will need to have
terrific reflexes to accurately measure a correct time as the time will be very
short. A better method involves the use of a quickly rotating mirror and a beam
of light. By aiming a beam of light o the rotating mirror, then reflecting it
o a second stationary mirror back into the rotating mirror, calculations can be
made on the speed of light. After first hitting the rotating mirror, the mirror
will rotate very slightly in the time it takes the beam of light to return and
will reflect back to a different position from where it came from. By measuring
the displacement of the round trip, a measurement of the speed of light can be
made.

Poznań Reasoning Week, consisting of three conferences, aims at bringing together experts from various fields, whose research focus on reasoning processes and their modelling from three perspectives:
the interplay of logic and cognition (Logic and Cognition 2016);
formal modelling of reasoning and argumentation (14th ArgDiap);
natural question processing (QuestPro 2016).
