QUES: The hourglass uses the flow of sand to measure the flow of time. They were used in navigation. Ferdinand Magellan used 18 glasses on each ship for his circumnavigation of the globe (1522). Incense sticks and candles were, and are, commonly used to measure time in temples and churches across the globe. Waterclocks, and later, mechanical clocks, were used to mark the events of the abbeys and monasteries of the Middle Ages. Richard of Wallingford (12921336), abbot of St. Alban's abbey, famously built a mechanical clock as an astronomical orrery about 1330. Great advances in accurate time-keeping were made by Galileo Galilei and especially Christiaan Huygens with the invention of pendulum driven clocks along with the invention of the minute hand by Jost Burgi.
In what year did Ferdinand Magellan build a mechanical clock?

QUES: Scientific and critical editions can be protected by copyright as works of authorship if enough creativity/originality is provided. The mere addition of a word, or substitution of a term with another one believed to be more correct, usually does not achieve such level of originality/creativity. All the notes accounting for the analysis and why and how such changes have been made represent a different work autonomously copyrightable if the other requirements are satisfied. In the European Union critical and scientific editions may be protected also by the relevant neighboring right that protects critical and scientific publications of public domain works as made possible by art. 5 of the Copyright Term Directive. Not all EU member States have transposed art. 5 into national law.
Are footnotes included in the copyright of the original work?

QUES: In Mark 15:25 crucifixion takes place at the third hour (9 a.m.) and Jesus' death at the ninth hour (3 p.m.). However, in John 19:14 Jesus is still before Pilate at the sixth hour. Scholars have presented a number of arguments to deal with the issue, some suggesting a reconciliation, e.g., based on the use of Roman timekeeping in John but not in Mark, yet others have rejected the arguments. Several notable scholars have argued that the modern precision of marking the time of day should not be read back into the gospel accounts, written at a time when no standardization of timepieces, or exact recording of hours and minutes was available, and time was often approximated to the closest three-hour period.
What did Pilate call for to make it easier to tell time?

QUES: Many environmental factors have been associated with asthma's development and exacerbation including allergens, air pollution, and other environmental chemicals. Smoking during pregnancy and after delivery is associated with a greater risk of asthma-like symptoms. Low air quality from factors such as traffic pollution or high ozone levels, has been associated with both asthma development and increased asthma severity. Exposure to indoor volatile organic compounds may be a trigger for asthma; formaldehyde exposure, for example, has a positive association. Also, phthalates in certain types of PVC are associated with asthma in children and adults.
