Insects attracted to light because they think it is the Sun, or is it just that they use them as travelling reference points?
Nobody really knows for
sure, but moths/Insects are thought to use the moon as a point of
reference to travel in a straight line. This might help to explain why
more moths seem to be attracted to artificial lights on nights when
there is no moon. If moths are drawn in very close to a bright light
source they may become dazzled, due to their eyes being unable to adjust
quickly enough to the sudden brightness, so will circle the light
instead of flying away from it.

You might imagine the inventor being someone from the Army or a policeman, but the true creator was a pizza delivery man! On July 21st, 1969, Richard Davis was delivering pizzas in Detroit when he was held up at gunpoint.
Luckily
for the former marine, Davis had a gun of his own and shot two of the
attackers but was hit twice himself. This incident gave him an idea for people like
cops to avoid injury by wearing padding of some kind. The first
prototype for the bulletproof vest was created by Davis out of a roll of nylon and the straps from his car’s seatbelt.
He
went around to police stations shooting himself in the chest to
demonstrate its power. Later, Davis created a second vest design using
Kevlar, which is 230% stronger than nylon.

renditions. Users usually have no procedure to put speed, distance and

The Nike+ Training system boasts of being the sole monitor that records
data, exercises it, and offers real-time coaching.
The system is made up of a couple of sneakers with Bluetooth-fitted sensors plus an iPhone app with
pre-programmed trainings. Throughout a training session, the app sends
out inspiring indications (like ‘Move faster!’) to the user. Once the
session is coplete, the app analyzes the user’s stats advising him on
his weak spots. The midsole of the Lunar TR1+ trainers has been
developed from Nike’s lightweight shock absorbent foam. The midsole
houses a printed circuit below the detachable sock liner, designed to
gather data of the user’s every single step. Sports sensor adds distance
and speed data from the available accelerometer, and the collective
data is then shared via Bluetooth 4.0 to Nike+ app. This sensor could be
charged through USB. The Nike+ app shall produce the results employing
some algorithms, which could be then referred by the user to better his
workout.
