In the same direction as the rotating hands of a clock
when viewed from in front.

From → clock + wise "way, manner,"
O.E. wise (adj.), from wis, from P.Gmc.
*wisaz (cf. Du. wijs, Ger. weise "wise"),
PIE base *weid-/*wid- "to see, to know;"
cf. Av vaeda "I know," Skt. veda "I know," Gk. oida
"I know".

Sâ'atsu, from sâ'at, → clock, + su
"direction," Mid.Pers. sôg, sôk "side, direction".

counterclockwise

پادساعتسو

pâdsâ'atsu (#)

Fr.: en sens inverse des aiguilles d'une montre

In a direction opposite to the rotating hands of a clock.

From counter- "contrary; opposite; opposing," + → clockwise.

Pâdsâ'atsu, from pâd-, → counter-,
+ sâ'atsu, → clockwise.

piecewise

تکهای

tekke-yi

Fr.: par morceaux

Denoting a → function that is defined on a sequence of
→ intervals or pieces. For example:
|x| = -x for x < 0, x = 0 for x = 0, and
x = x for x > 0.

A function f(x) in an interval if :1) the interval can be divided
into a finite number of pieces in each of which f(x) is continuous, and
2) the limits of f(x) as x approaches the boundary point of each
piece are finite. In other words, a piecewise continuous function is one
that is made up of a finite number of continuous pieces.

A → NASA infrared astronomical → space telescope
launched in December 2009
to carry out an → all-sky survey from 3 to 22
→ microns.
With its 40-cm → telescope
telescope and → infrared cameras,
WISE aimed at a wide variety of studies
ranging from the evolution of → protoplanetary disks
to the history of → star formation
in normal galaxies.
In early October 2010, after
completing its prime science mission, the spacecraft ran out of
→ coolant
that keeps its instrumentation cold. However, two of its four
infrared cameras remained operational. Hence,
NASA extended the NEOWISE portion of
the WISE mission by four months, with the primary purpose of hunting
for more → asteroids and → comets,
and to finish one complete scan of the
main → asteroid belt.
In August 2013, the WISE telescope's mission was extended for more
three years to search for asteroids that could
collide with Earth.
