“ONE DOWNSIDE OF A POWERFUL BRAIN LIKE OURS IS THAT EVEN THE MOST ABSTRACT THINGS CAN BE PERCEIVED AS A ‘THREAT’”
DR DEAN BURNETT, p28
LETTER OF THE MONTH
A matter of time
In your July issue, your pick of the month’s smartest technology was a watch that could withstand the harsh environment on the surface of Mars (p42). It was priced at £6,100.
For that sort of money, I would like a watch that doesn’t lose 40 minutes per Martian day [days on the Red Planet are 39 minutes and 35 seconds longer than ours, here on Earth]. The watch is better as a wall clock for checking what time it is back home, not for someone actually checking the time on Mars. Did not one horologist consider the length of a Martian day?
