Daylight Saving Time 2017

 from WikiMedia Commons

So, when exactly do we reset our clocks? And is it forward or backward one hour?

Daylight Saving Time can be very confusing. First of all, the very phrasing is often confused: it's Saving not Savings. We are saving daylight not putting something in a savings account. Read below to help end your confusion! [The chart on the left plots the times of sunrise and sunset (with DST adjustment as separate lines) in Greenwich, GB for 2007.]

Short answer
For the Spring- On Sunday, 12 March, 2017 at 2:00am, you should set your clock forward one hour to 3:00am.

For the Fall- On Sunday, 05 November, 2017 at 2:00am, you should set your clock backward one hour to 1:00am. (Remember "spring forward, fall back...").

Easy answer: Most people who go to bed earlier than the wee hours of the morning simply set their clocks back/forward one hour before they go to bed on Saturday.

Science and the Rio Olympics


from Marlbrooks biomechanical analysis video below
Zika? Water pollution in Brazil? Biomechanics of Olympic athletes? Want to know more about some of the issues happening at the 2016 Rio Olympic Games from the point of view of science?

University Libraries has information.

Random facts to get you started (sources: see links below):
  • False starts in track are signaled when a runners applies pressure to the starting block within 100 milliseconds of the electronic gun which is faster than a human’s nervous system can react
  • Time keeping clocks used in the Olympics measure to the 1000th of a second
  • Fast pools” are engineered to reduce turbulence so that swimmers can swim faster by making the pools deeper (3 meters),
    • having lanes proportionate to the pool width (the wider the lanes the better – 2.5 meter lanes for an 80 meter pool is standard),
    • source: Wikimedia Commons
    • having side troughs that help prevent waves from rebounding back into the pool,
  • lane line markers convert wave energy into spin rather than letting waves pass into other lanes
  • Zika virus
    • can not only pass through a mother’s placenta to the fetus but may also be sexually transmissible
    • Zika mosquitoes (Aedes aegypti and Aedes albopictus) are active during the day which renders malaria netting ineffective (malaria mosquitoes (Anopheles) are active at night)
  • Fecal matter in Guanabara Bay is 198 times higher than the legal US limit
  • 55 rivers and 8 million residents in 15 nearby cities bring over 18,000 litres of sewage per second into the bay
