Interview of Computer My Teacher
Hi everyone... Today I'm supposed to make an article about my computer teacher. So here it is:
My teacher's name is Mr. Widyamukti Wicaksana but we call him Pak Wiwiet. In Nizamia he works as a Computer teacher and great at dealing with computer stuff. Even tough he is a computer teacher he is also a Ghrapic Desinger and a Cartoonist. Here is how he stared the job as a teacher; He Volunteered
in Komnas PA w/ kakak Seto., The he teached some non-formal school, then he became a teacher in: Lazuardi, Darul Qur’an, then Nizamia. He has been a teacher since 2005- until now.
This is how he became a teacher in Nizamia:
One day he did cycling and he got lost because he was excited to try a new path/track and he reached Super Indo supermarket. He kept cycling and found a weird blue and yellow building and it was an Elementary school called Nizamia Andalusia “wow there’s a school here” He said. The last name “Andalusia” made him interested, he searched and the school opened a position for teachers and since the school was near his house he applied there.
Here is some extra things about him:
- Sports that he like: Football, Camping, Cycling, Hiking, good defender, and motor sport.
- His Age: Born 1987. Age 28 (?)(not so sure).
- How he feels working in Nizamia Andalusia: Sometimes he has a bad day when students don’t corporate , but sometimes he likes it.
- His Favorite Football Player: Greeme Le Saux (FormerEngland international Player and Chelsea), Paolo Maldini (Former Italian and AC.Milan), A. Del Piero (Former Italian/Jeventus), and Ismed Sofyan (Persija).
- His Favorite People in the world: Mom,dad,wife, and baby.
- His favorite Food: Ramen, Fried Rice, and potato.
- His favorite Dessert: Ice Cream, éclair Where do you live: Mampang 11

Measurements Standard Based on International Unit
Measurement
Standard Based on International Unit
The International System of Units (French:
Système International d'Unités, SI) is the modern form of the metric system,
and is the most widely used system of measurement. It comprises a coherent
system of units of measurement built on seven base units. It defines twenty-two
named units, and includes many more unnamed coherent derived units. The system
also establishes a set of twenty prefixes to the unit names and unit symbols
that may be used when specifying multiples and fractions of the units.
The system was
published in 1960 as the result of an initiative that started in 1948. It is
based on the metre-kilogram-second system of units (MKS) rather than any
variant of the centimetre–gram–second system (CGS). SI is intended to be an
evolving system, so prefixes and units are created and unit definitions are
modified through international agreement as the technology of measurement
progresses and the precision of measurements improves. The 25th General Conference
on Weights and Measures (CGPM) in 2014, for example, discussed a proposal to
change the definition of the kilogram.
History:
The metric system was first
implemented during the French Revolution (1790s) with just the metre and
kilogram as standards of length and mass respectively. In the 1830s Carl
Friedrich Gauss laid the foundations for a coherent system based on length,
mass, and time. In the 1860s a group working under the auspices of the British
Association for the Advancement of Science formulated the requirement for a
coherent system of units with base units and derived units. The inclusion of
electrical units into the system was hampered by the customary use of more than
one set of units, until 1900 when Giovanni Giorgi identified the need to define
one single electrical quantity as a fourth base quantity alongside the original
three base quantities.
Base
units:
Main article: SI base
units
The SI base units are
the building blocks of the system and all other units are derived from them.
When Maxwell first introduced the concept of a coherent system, he identified
three quantities that could be used as base units: mass, length and time.
Giorgi later identified the need for an electrical base unit. Theoretically any
one of electric current, potential difference, electrical resistance,
electrical charge or a number of other quantities could have provided the base
unit, with the remaining units then being defined by the laws of physics. In
the event, the unit of electric current was chosen for SI. Another three base
units (for temperature, substance and luminous intensity) were added later.

Note
- Jump up^ Interim
definitions are given here only when there has been a significant difference
in the definition.
- Jump up^ Despite
the prefix "kilo-", the kilogram is the base unit of mass. The
kilogram, not the gram, is used in the definitions of derived units.
Nonetheless, units of mass are named as if the gram were
the base unit.
- Jump up^ In
1954 the unit of thermodynamic temperature was known as the "degree
Kelvin" (symbol °K; "Kelvin" spelt with an upper-case
"K"). It was renamed the "kelvin" (symbol
"K"; "kelvin" spelt with a lower case "k")
in 1967.
- Jump up^ When
the mole is used, the elementary entities must be specified and may
be atoms, molecules, ion, electrons, other particles, or specified groups of such particles.
The
original definitions of the various base units in the above table were made by
the following authorities:
- FG =
French Government
- IEC = International Electrotechnical Commission.
- ICAW = International Committee on Atomic Weight.
All
other definitions result from resolutions by either CGPM or the CIPM and are
catalogued in the SI Brochure.
Founders:
Metre: John Wilkins
Ampre: André-Marie Ampère
The
derived units in the SI are formed by powers, products or quotients of the base
units and are unlimited in number.[22]:103[33]:3 Derived units are associated
with derived quantities, for example velocity is a quantity that is derived
from the base quantities of time and length, so in SI the derived unit is
metres per second (symbol m/s). The dimensions of derived units can be
expressed in terms of the dimensions of the base units.
