Silicon - Periodic Table of Videos

[peamcdonnell]

The silikin

[chuckyghostarmy]

did you really grow your hair that long or was it a wig

[krater97]

Booob implants

[srgwarcock]

Needed to do a report on silicon, Thanks Periodic your the Beez kneez

[OO7ACEMASTER]

20 nanometers thick!

[Quasi84]

I would like to see a video of how silicon becomes a central processing unit.

[pug6666]

@Quasi84 Yea if sand is silicon oxide then how do you tear them apart from the compound i doubt just melting would do that.

[Wulf96]

@Quasi84 Go watch the TV show "How it's Made" on science channel. They made an episode on the chips and the boards. Also try the show "How do they do it?", it's also on science channel.

[zimtower]

@Quasi84 /watch?v=tmW-ax8fjqU

[JadeWentz]

I love that he just has a wafer of silicon in his office!

[mykasikna]

1:45 so let me take that. lol voice :D



[macro312]

He is got every trembl-y hands.

[vlptr]

@macro312 Yeah, and?!

[macro312]

@vlptr

It is an observation. AND The professor is awesome.

[Stormdude100]

where can I get silicon?

[OOZ662]

One of my old teachers has a wafer of Pentium 3 processors. I always loved bringing out out and showing it to the Freshmen; their eyes would get huge and they'd almost always want to take it home.

[punishedexistence]

5 people don't like computers.

[alasanof]

I wonder if silicate aliens use carbons for computing...

[nonchalantgamer]

@alasanof Are you high?

[alasanof]

@nonchalantgamer I'm just wondering if its possible for Carbon to be used in computing since there can be living organisms made mainly of Silicon.

[nonchalantgamer]

@alasanof It just sounded like something someone would say when they're high, lol. Yeah, it probably could. Carbon is conductive isn't it?

[PGordonKennedy]

5 people dislike silicon and yet without silicon they couldn't even watch this, let alone dislike it! :)

[MagaCarey]

Is there a possibility to make a new video on Si, please?

I've just read a viewer that mentions the idea of Si-based life. I thought it was quite interesting.

I also have a question about Si in food. I was reading the ingredients of cat food and Silicon Dioxide was there. I immediately starting doing some research. Is Si important in our diets also? It's never mentioned.

[BigTex541]

@MagaCarey Silica (SiO2) is acommon additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications.

[rageagainstthebath]

@MagaCarey It's rather strange that Silicon Dioxide is in your cat's food, because it's just a pure sand (As the Prof said in this movie)...

[Xyrosis]

@MagaCarey

I'm quite sceptical of silicon based lafe because all though silicon forms four bonds like carbon, it has rather difficulty forming double and triple bonds. disilenes for instance are quite reactive, and disilynes more so. Many organic carbon compounds found in nature contain double and lesser so, triple bonds.

[silverchill1]

now we know why the professor wasn't a surgeon

[GRAHAMAUS]

Is there a silicon analogue of diamond?

[replypdf]

What about silicon in solar cells? How and why is it used?

What about black silicone which supposedly should make more effective solar cells?

Thanks for the good videos.

[HighlordSarnex]

@replypdf ah and those are a question for another time... or the internet whichever you prefer xD

[XxWearsMexX]

@replypdf because silicon is a semi conductor, therefore allowing the photons to excite the electrons and create a current.

[Alkinoos7]

Hey I got a question: Could it be possible for silicon-based life to exist? I know this is a wide issue but I can't stop wondering about the possibility of life that's based on silicon...

[efrem1]

These videos are good introductions to the elements. Makes me want to get a chunk of indium for example and study it.

[onimotoko]

Silicon may be the single most important element in the modern world.

[ShadowRayzzz]

@onimotoko Erbium is just as important

[onimotoko]

@ShadowRayzzz without silicon erbium would not have any value in computers. No computers, no internets.

[ShadowRayzzz]

@onimotoko You can always go deeper, without Carbon, you would not exist, hence computer would not exist :P

[lockheed22]

Wow, what schmucks disliked this?

[HRHooChicken]

Poor guy, he shakes a lot. I don't think that university provides propper central heating

[TheSpeshulShark]

@HRHooChicken It doesn't. My dad works there, and is always complaining xD

[Muscleduck]

That wafer is awesome!

[schmidtbag]

damn how'd they get their hands on intel's wafers? i'd like one of those

[lamvutran]

that guy looks very much like Jamie Oliver

[onceigoblack]

have i said that children are no challenge?........

[Sheggy6626]

@onceigoblack yes

[Evaldas521]

@serialkissersband

make some?

[AdventLt]

That plate of silicon cost plenty of money :)

[mafl25]

I want that waffer!

[buddahlover419]

that waffer he is holding is hella expensive and his shaky hand when he lets go with the other hand and his right hand starts to shake it makes me hope he paid for it so if he breaks it some one else isnt assed out of alot of money lol

[DasutinD]

that waffer isn't expensive, I would say its worth between $50 and $100 now, back when it was made it was probably worth $5,000, those are all P4 chips

[buddahlover419]

and who is to say he didnt jus aquire it recently before the video was made? and how many people realy have a waffer in that good of shape i have a bunch pentium 1 waffers in a storsge tray that i got wen my stepdad worket @ intel installing pipes for there cleanrooms unfortunatly they were all baddly damaged

and only had 4 out of maybe 40 of em were intact

[carl0071]

@DasutinD probabely less than that... most of the cost of a pentium 4 is in the gold connecting pins

[schmidtbag]

@carl0071

actually, most of the cost is the architecture and fabrication systems. the pins are gold PLATED, so they're not even entirely gold. you can find new cpus for less than $40 that have more pins than the socket 478 p4, and the reason they're so cheap is because they don't offer anything special in today's standards

[thingy291]

does this guy have to go for the mad scientist look?

[cthulhex]

The professor looks rather placid, not mad at all.

[Sheggy6626]

@thingy291 NOOOOO!!!

[denelson83]

So how come silicon nitride isn't used for the fuselage of an aircraft?

[BluBreathProductions]

it's probably too expensive

[divinerbird]

1- expense

2- it is a ceramic, so while it's tough, it undergoes brittle failure (its shatters, rather than bends or deforms). This type of failure happens with very little warning - very bad if you are using it for structural support or if lives depend on it.

[thrunt]

These videos are so hokey. "Here is a lump of silicon, its used for stuff".

Why not cleave the big wafer ( pressure from a screwdriver for instance on the edge) and show the cubic structure. These guys have obviously never actually done any silicon chemistry or any semiconductor work. What about pointing out the analogies with carbon chemistry.

[Sheggy6626]

@thrunt x wrong. he is professor.

[marcusduck]

What's the difference between silicon and silicone?

[Bendeco08]

erm silicon on this video is the metal and silicone is like rubber stuff lol

[tastythighs180]

silicon is in computers, silicone is in pamela anderson. any questions?

[marcusduck]

hey man, don't think dirty...thanks for the info anyway.

[nonchalantgamer]

@tastythighs180 Pamela Anderson is in my computer.

[ltjb145]

@tastythighs180

what does silicon react with?

[jlmadill]

@ltjb145 Silicon reacts with JUSTIN BIEBER

[BruceNJeffAreMyFlies]

@tastythighs180 Technically, silicon is also in pams chesticles. Silicone is made partially from silicon.

Just a tidbit of info for ya.

[madamerotten]

Silicone is a synthetic rubber based on silicon, carbon, oxygen, hydrogen, among other elements.

[dbc616]

Yes, silicone is a polymer. You can actually make it in the lab by mixing ethanol with sodium silicate solution.

[BluBreathProductions]

Silicon is the metal. Silicone is a polymer rubber containing silicon, carbon, hydrogen, and oxygen.

Don't kill yourself with thallium!

[nepssis]

Silicon is metalloid :p

[zakyb1]

and whats with all the bottles at 3:13  ???

[kyu5289]

Answer's in the video for Manganese!

[zakyb1]

the prof has shaky hands!

[polonium9]

can i buy one of those wafers???!?!?!?!? (i dont want to eat it)

[Draxis32]

Metallic Silicion, i think its even more expensive than metallic titanium, this materials are surrounding us, but their god damn oxides are extremely hard and expensive to obtain the metallic material from them.

[joeleatsbk]

sure you dont want to eat it

[100PercentGeeks]

Om nom nom Silicon Wafer.

[aswhit5]

silicon is an outdated semiconductor. we have found many better molecular compounds for use in optoelectrical devices. mainly polythiolene derivatives.

[Gomka1000]

Mmm... Silicon wafer...

[hereosinerror]

lol

[AceProgrammer]

lol lol

[EmeraldxFairy]

No wonder Opals are so beautiful and reflect light magnificently. They are made of Silicon Dioxide (SiO2). :) Wonderful!

[tomandjj]

silicon doesn't make small enough transistors anymore they have to use sapphire computer chips instead.

[saintaureus]

That's not true at all. If you're referring to "silicon-on-sapphire" technology, the sapphire is a separate layer which is used for data transfer. The transistors are still silcon.

[tomandjj]

mmm that's what I meant sorry. we can't make transistors any smaller without placing them on a sapphire chip instead of a silicon one I helped do this at the University of Queensland here in Australia.

[Ormaaj]

you can use germanium

[tomandjj]

sapphire is slightly better I think. but yes you are right we also did germanium ones.

[corght]

shaky hands

[rekinu5]

what is silicium, a fruit so that it grows? sounds funny.

[bennemann]

Silicon is called "silício" in portuguese and I believe spanish also has a similar pronunciation. So it's no surprise that some people mix up the two and say silicium. It makes alot more sense than silicon anyways, as most other elements end with -ium (rubidium, einstenium, gadolinium... I could go on all day)

[rekinu5]

my point was not the name, i heard them saying that it GROWS, thats why i said that it is a fruit. which seemed to be weird. besides i think the name Silicium Comes From LATIN

[bennemann]

When did I say it does not come from latin? Portuguese are spanish are derived from latin, that's why our continent is called Latin America :)

[rekinu5]

first of all , i knew that latin America was the place between n and south america, wher cuba is.OK W/E call it w/e u want . i will call it silicium. this is how my chemistry teacher thought me like this and i will call it silicium. or simply , maby they call it silicium in romania, how may u know.

[moomilkboy]

wow he just handled a couple hundred bucks worth of pentium 4 processors like it was nothing

[JeffreyRodriguez]

Could be a wafer with too errors or something. I imagine there are quite a few of those.

[bruenor82]

i just noticed...nice mug

[superASSschaf]

rofl...my sister has that mug :p

[danbison]

I know some silly Kates.

[mullingitover]

That afro is powerful. Respeck.

[Bugstomper2]

Looks like Einstein there shampoos his hair with sand!

[JasoniumGH]

lol his hands shake when he was holding the silicon disc

[bruenor82]

give him a break man, you'll get that when your his age

[alanna4858]

go into it!

[soulesseye]

ok he clearly says "here you see where people have GROWN chips"so i have to say ketamunke prove that what he said is wrong.unless u can i have to say u dont know what your talkin about.also i wonder if it would be possiable to use silicon crystals to store information with out converting it to chip's.like use beams of laser light and the refraction of the light as a way to transfer information.

[xNAgff]

I so want one of those wafers.

[Asurael]

I wonder if Professor Martyn has Parkinsons of Parkinson-like tremors. Either that or he just gets nervous in front of the camera.

Great video as usual :P

[FrostPegasus]

Maybe it's the age. :-P

[atomic7732]

You forgot about silicosis!

[Bernler75]

In boobs it is plastic with silicon in it I would guess...

[HLSDK]

breat implants are sillicone, rather than sillicon. Despite the name, they are pretty different materials. It just wouldn't feel very nice with silicon!

[DeanMalenko]

@HLSDK it's easier in german :D we cann this element "Silicium" and the plastic stuff in breasts "Silikon" so it sounds diferently

[JoeCfb]

Metal boobs, lol.

[Mofo3210]

That's silicone, not silicon :)

Also you have the silicon walley, given the name due to the mining of silicon.

[bennemann]

you mean valley =)

[winterstellar]

Hello? I think you forgot the most important use of silicon! Boobs, how do they make silicon boobs? :) Haha!

[Arkphyre]

Mm I think that's silicone, this is about silicon.

[BB1951]

Boobs made of silicon would be very strong and very light.

Silicone on the other boob... :)

[sheeselectric]

great videos! thanks but i was just wondering, what do they mean "grow" the chips? can someone explain a bit on how they do it?

[ketamunke]

They don't actually grow the chips. They form giant plate crystals of almost pure silicon (it actually has a little bit of arsenic and sometimes other elements). Then, they etch the actual chip components onto the silicon wafer by a variety of methods. A common first step is to remove oxides of silicon with hydrofluoric acid. Remember, don't breathe this! Hydrofluoric acid is bad stuff. It can penetrate your skin and eat your bones. Anyways, it would be mighty cool if they could just grow a chip

[CharlieBBoy12345]

What is it about silicon that makes it useful to computing? Is it the way it can be grown on wafers as the vid showed, or are there other properties of it that make it appropriate?

[AaronAlso]

It is classified as a semi-conductor that is primarily what makes it so special.

And...

the waste silicon from CPUs is not just tossed out much of it goes to be used in photo-voltaic cells. (solar panels)

[AaronAlso]

Doh! forgot th important part...

/wiki/Silicon

[CharlieBBoy12345]

Thanks - good old wiki!

[Samhains]

The man with the hair, LOVE THE HAIR, I could listen to you guys all day talk about alchemistry, Hey wasn't that guy in the green jumper in Shawn of the dead? ,, No..anyways, can you eat it?,,what, Iam just kidding..

5 star..and don't forget the wash your hands.

[ColevanFilms]

Superb video.

[Festerius2008]

I knew that sand contained silicon but I didn't realize it was an oxide of silicon! Silicon is one of my favorite elements. So important to the electronics industry!

[sillypiggy2]

sweet i love all this stuff
