  A novel method is proposed to monitor and record scientists' working
timetable. We record the downloads information of scientific papers real-timely
from Springer round the clock, and try to explore scientists' working habits.
As our observation demonstrates, many scientists are still engaged in their
research after working hours every day. Many of them work far into the night,
even till next morning. In addition, research work also intrudes into their
weekends. Different working time patterns are revealed. In the US, overnight
work is more prevalent among scientists, while Chinese scientists mostly have
busy weekends with their scientific research.
