Search Tips
In order to get more accurate results, our search has the following Google-Type search functionality:
+
If you use '+' in front of a word, then that word will be present in the search results.
ex: Harry +Potter will return results with the word 'Potter'.
-
If you use '-' in front of a word, then that word will be absent in the search results.
ex: Harry -Potter will return results without the word 'Potter'.
AND
If you use 'AND' between two words, then both of those words will be present in the search results.
ex: Harry AND Potter will return results with both 'Harry' and 'Potter'.
OR
If you use 'OR' between two words, then bth of those words may or may not be present in the search results.
ex: Harry OR Potter will return results with just 'Harry', results with just 'Potter' and results with both 'Harry' and 'Potter'.
NOT
If you use 'NOT' before a word, then that word will be absent in the search results.
ex: Harry NOT Potter will return results without the word 'Potter'.
""
Placing '""' around words will perform a phrase search. The search results will contain those words in that order.
ex: "Harry Potter" will return any results with 'Harry Potter' in them, but not 'Potter Harry'.
*
Using '*' in a word will perform a wildcard search. The '*' signifies any number of characters. Searches can not start with a wildcard.
ex: Pot*er will return results with words starting with 'Pot' and ending in 'er'. In this case, 'Potter' will be a match.

Brief History of Timekeeping
336
You only need to press the snooze button on your alarm a bit too often to understand the importance of good timekeeping. What you might not know is that the need to tell the time connects you to over five thousand years of human history, from the first solstice markers at Newgrange to quartz crystal oscillating in your watch today. Science underpins time: from orbital motion and axial tilt to the quantum mechanics and relativity theory that gives us our ultra-precise atomic clocks. Yet time is also socially decided: the Gregorian calendar we use today is a result of complex political negotiations. The ancient Maya used sophisticated astronomical observations to produce a calendar system unlike any other in the world. In his quirky and accessible style, Chad Orzel reveals the wondrous physics that makes time something we can set, measure and know.
