Kako vizualizirati milijunti dio - Kim Preshoff + TED-Ed zajednica

Prevoditelj: Tamara Rabuzin Recezent: Ivan Stamenković

What does it mean to be one in a million?

Što to znači biti jedan na milijun?

Not in the greeting card sense,

Ne u smislu teksta na čestitki,

in the scientific sense,

već u znanstvenom smislu,

where one part per million is a unit of measurement.

gdje je jedan prema milijun jedinica mjere.

Parts per million counts the number of units of one substance

Broj dijelova prema milijun znači broj jedinica nečeg

per one million units of another.

prema milijunu jedinica nečeg drugog.

It can measure concentrations when a small amount makes a big difference.

Primjerice kada mala koncentracija nečeg čini veliku razliku.

For example, a concentration of just 35 ppm of carbon monoxide in the air

Na primjer, koncentracija od samo 35 milijuntih dijelova (ppm) ugljičnog monoksida u zraku

is poisonous to us.

je otrovna.

We encounter measurements like this pretty often,

S ovakvim mjerama često se susrećemo,

but because it's hard to conceptualize really large numbers,

ali kako je teško pojmiti jako velike brojeve,

it's difficult to wrap our brain around what one part per million really means.

teško je zamisliti što to milijunti dio zaista znači.

So here are nine helpful ways to visualize it.

Ovdje je devet načina vizualizacije.

If you had 11,363 pianos-worth of piano keys,

Ako imate onoliko tipki koliko ih je sadržano u 11363 klavira,

one of those keys would be about one part per million.

jedna takva tipka bila bi otprilike milijunti dio.

So would a single granule of sugar among 273 sugar cubes,

Kao i jedno zrnce u 273 kocke šećera,

one second in eleven and a half days,

jedna sekunda u jedanaest i pol dana,

or four dots in the painting,

ili četiri točkice u slici

"A Sunday Afternoon on the Island of La Grande Jatte."

"Nedjeljno poslijepodne na otoku La Grande Jatte".

Your bath tub's capacity is about 60 gallons,

Kapacitet vaše kade je otprilike 60 galona (227 litara),

so seven drops of ink would be one part per million.

pa bi sedam kapi tinte bio milijunti dio.

The English version of the Harry Potter series has 1,084,170 words,

Engleska verzija serije knjiga Harry Potter ima 1 084 170 riječi,

which makes "hippogriff" on page 221 of "The Prisoner of Azkaban"

pa je "hippogriff" na stranici 221 knjige "Zatočenik Azkabana"

a little less than one part per million.

malo manje od milijuntog dijela.

A million kernels of corn is about 1,250 ears,

U 1250 klipova kukuruza nalazi se oko milijun zrna.

so one kernel in that truckload would be one part per million.

pa bi jedno zrno u takvom kamionu kukuruza bilo jedno na milijun.

There are 10 million bricks in the Empire State Building,

Empire State Building sagrađen je od 10 milijuna cigli,

so one part per million would be a pile of just ten.

pa bi hrpica od deset cigli bila milijunti dio ove zgrade.

And finally, 100 people worked together to animate this video.

Konačno, 100 ljudi radilo je zajedno na animaciji ovog videa.

Collectively, they have about 10 million hairs on their heads.

Oni zajedno imaju oko 10 milijuna vlasi na glavi.

Pluck ten of those hairs, and you have one in a million.

Kad bi se iščupalo deset vlasi, to bi bio milijunti dio.
