How Small is a Nanometer? Choose your favorite!

[huyked]

I like the 3rd one too.

[ercheksargo]

As thick as half a brick? Boy! Think of 1 millimeter stretched to 1,000 kilometers (Sydney to Brisbane). On this 1,000 km long road 1 millimeter is your prescious NANOMETER! Woopee!

[Dragonsayian]

@ercheksargo Actually your as little off If a 1mm was stretched to a 1,000 meters a (kilometer) then a Nanometer would be A millimeter .Okay a Nm is 1 million times smaller than an Millimeter and a MM is a million times smaller than a Kilometer . If your stretched a meter then you answer would be right on .

[ercheksargo]

@Dragonsayian Yeah, you're right! Thanks for the correction, i nearly broke my brains on this one. Hahaha.

I Like The #3rd Video ;)

[cordlehman]

The first one. They showed this in my class, and get this, they all looked like our teachers!

[localhorstx]

The last one.

[HdBurningblade]

the last one

[gilbeth77]

Video 2 best describes it too me since they actually said how big a nanometer is (one billionth of a meter) good job #2

[vicwooten1234]

whoa. if the answers are correct, really whoa

[apton77]

Folks, these are analogies, not scientific proofs. They are probably doing their best to explain nanometers to lay people, museum visitors and the like, and do it in a fun way. The first one was fun, the second got too crazy, but the third was quick and easy. Much like myself. :-)

[88droid]

so what the hell is the nanometer usefull for then just for molecules and atoms?

[tranceology3]

A nonometer is just a term for a very small meter, just like a cenitmeter, millimeter, etc....

It's usefull for everything that is very small, more typical would be current CPUs like a 45nm (nanometer) cpu.

[julian1000]

Numer three is est.

[Agen0]

1 million molecules? You´re kidding right? 1 million molecules is NOTHING.

[Jettboi93]

the first one for the win Duhh...

[mangoLE10]

Third one, it's nice and simple. Noticed an error in this though, there is no such thing as a salt molecule! (a molecule has covalent bonds). Salt is an ionic compound and therefore consists of ions not molecules.

[Born2killx]

Haha, you just pwned museum people!

[kamayarii]

@mangoLE10 Ionic compounds can still be thought of in terms of formula units and unit cells. What he referred to as a molecule of salt there was a unit cell of NaCl.

[alliepeterson16]

the minicooper and cheerleaders one describes it the best. WOW thats small.

[xtrollhammerx]

third vid fr sure

[ecume111]

Salt and the Museum one

[myocardialinfarctio]

I'd say the museum clip!

what's the song called at the very end?

[stiffdog5000]

Salt and the museum

[anothercrusader]

Got to be the one with the salt. People Identify with salt. They put it on their food everyday. Though for succint arguments, the marble and planet earth wins hands down.

[trailkeeper]

I think the third vid. That's if he was describing in terms of the diameters of the marble and Earth. Annother way to describe it is a millimeter (that we can see) is a thousandths of a meter or 0.001m and a nanometer is a millionths of that or 0.000,000,001m

[Kadda67]

the first vid is the best

[educationNYHS]

I thought the video clip were easy to watch and clearly got the point across. I especially liked the hint of humor.

[elvemageownz123]

i tnk the car one

[Monsterenergy791]

marble one/3rd

[cobaltblu71]

I have to ask, what museum is that?

[educationNYHS]

Boston Museum of Science.

Visit the New York Hall of Science when in Queens, NY

[Bo0sh]

marble

[SailorBarsoom]

I'll go with the car.

[roidroid]

car one, no. i can't visualise what 6 billion people looks like.

the salt one. What's with the green ball prop? a ball is NOT the size of a grain of salt.

the marble one. the small globe in the background confuses the context.

i vote marble. it was so short it didn't have the chance to make many mistakes.

[chickenflicker]

Agreed with angloquebecer. I think the first video was pretty good though.

[DrLight9]

3rd

[angloquebecer]

Except that using the 6 meter diagmeter MODEL of the Earth behind him misleads the viewer ever so slightly to compare the marble size to the MODEL Earth size rather than the real earth size. You have to do a "double think" to comprehend.

[pat637]

the first one was a little vague (i guess i'm a dummy). I think she should have clarified that there will still be extra space in the car even after fitting the earth's population. i got confused when she showed the matchbox type car model i had to see it twice lol. i vote for 1, simply rephrase the last statement.

[hellokitty2112]

How many atoms are there in a nanometer?

[NanoNerds]

It varies depending on the element believe it or not. For reference though, roughly six gold atoms is about one nanometer.

[juryofpeers]

And about ten hydrogen atoms in one nanometer. Hydrogen atoms are the smallest of the atoms because they only have one proton, one neutron, and one electron.
