A is for Atom - Part 1

[psyberyeti]

How can anyone dislike the video?

[gwendance]

cosmic glue aka the strong force

[secretTonystoneberry]

This video is awesome. Please post more videos like that more on YouTube. 

[TheLovesoul1]

nice.

[ZetanCrisp]

This question is slightly off topic but not completely: Does anyone know how much the weight of the Earths atmosphere is responsible for holding us on to the planets surface? In other words, if all the atmosphere were removed and we jumped in the air would we stay up longer without the weight of the air on us? How much would we actually weigh if we stood on a weighing machine without the weight of the atmos pushing down on us?

[westcoastlife4show]

@ZetanCrisp theres a constant 14.7 atmospheric pressure thats what i know lol

[ReligionInTheBin]

Nu-ki-lar

[SpaceTime4D]

@ReligionInTheBin Huh? What does that mean?

[ReligionInTheBin]

@SpaceTime4D

Say it out loud :)

Tip: /watch?v=hORaebYWDwk

[SpaceTime4D]

@ReligionInTheBin Sorry it took so long for me to get back, it says "nuclear". But electrons are outside the nucleus, and thus are not nuclear. Unless they are in the form of beta particles ejected from a radioactive nucleus. But beta particles are free and do not have orbitals.

But can you teach me on drawing d, f, and g orbitals?

[SpaceTime4D]

Personification is always good in explaining science concepts. And humor. That's what makes this so good.

[Kenoburned]

if the "glue" that sticks atoms together is removed, then will the free particule lose their mass? like does a free electron has a mass?

[SpaceTime4D]

@Kenoburned The "glue" is really the strong nuclear force (which carries happen to be called "gluons"), holding together the protons although they electromagnetically repel each other. Neutrons are also affected by the strong force, aiding the holding of protons together. If there were no strong force (or "glue"), nuclei would fly apart as protons repel one another.

[Kenoburned]

@SpaceTime4D i understand that but they say that the force(well the gluons as you say) that binds protons together is what gives the atom a mass, but does the atom lose its mass if the protons get separated from each other. i mean, will each proton lose its mass if they get separated from each other.

[SpaceTime4D]

@Kenoburned The gluons themselves are simply carriers of the strong force, and have no mass of their own: gluons are pure energy. When protons are seperated from one another, there is a chance a gluon is coming from one to the other, but the other is no longer there, due to the neutron being fired. The gluon in the middle of nowhere is somehow converted into a photon and heat.

[SpaceTime4D]

@SpaceTime4D (continued) Since mass and energy are ultimately the same, the total weights of the two atoms after fission is slightly less than the initial weight of the U-235. The rest is the energy released. But the protons themselves do not lose mass.

[Kenoburned]

@SpaceTime4D lol a bit complicated for me right now i think ill stick with my current chemy for now (we are learning S P D F orbitals and how to draw them and place elctrons inside xD) Well thx for the info tho i was curious. I think its confusing all those things like quark , antimatter, gluon, photon...i understand what a proton and electron are but for the rest im confused. I know photon is what conposes light but i still dont get if its a particule or not...

[SpaceTime4D]

@Kenoburned A photon is a wave AND a particle at the same time. Maybe I'll soon explain to you the basics of particle physics, if you then teach me how to draw the different orbitals (I'm making my own cartoon atom characters, like what they have here, mine which are in the shapes of the orbitals).

[Kenoburned]

@SpaceTime4D Well you know, we are not learning to draw them artisticaly on a computer with super great 3D graphics of the death. We just draw them on a paper sheet, the real point is just to place electrons in them so you see i dont think i could really help you lol i suck at drawing.

[SpaceTime4D]

@Kenoburned I am drawing mine on a paper sheet, too.

I want you to please teach me how to draw the different orbitals.

[TheLovesoul1]

@Kenoburned it just takes time you'll get better at it.

[domyaska]

great!!!!!! amazing video..!! grazieee

[ZetanCrisp]

Nice clear description, thanks!

This got me thinking - What exactly is an explosion, or in other words why does it go or expand outwards? I reminds me of what happens when a balloon is popped? High pressure expanding into a low pressure?

[SpaceTime4D]

@ZetanCrisp The chain reaction produces much heat and light. The principles of entropy dictate that the heat must spread out. Light just naturally spreads out in all directions. This heat and light is so much and spreading so fast it is released as an explosion, unless it is slowed, as shown in Part 2.

[ZetanCrisp]

@SpaceTime4D Thanks for your reply.

Another question: When the Uranium atom(92 on the Periodic table) is split into 2 why doesnt each half become Palladium which is 46 on the Periodic table?

[SpaceTime4D]

@ZetanCrisp It's a matter of probability. It is theoretically possible for the uranium atom to split into two palladium, but it is much more likely that there will be, for instance, silver and rhodium. There are more ways for the atom to break irregularly than regularly, and probability favors irregular. There is a small chance a splitting atom may result in palladium, but it is quite unlikely.

[ericscerri]

quaint video,

If you liked it also see, the book,

Eric Scerri, The Periodic Table, Its Story and Its Significance, Oxford University Press, 2007

for a more up to date view.

[nickharvey7]

I really like these old videos!!

[nickharvey7]

In my video The Paradox of Schrodingers Cat an artist view Time has symmetry and geometry could this explain the paradoxes of quantum mechanics?

[exeuroweenie]

Funny how old media can be at once cute,creepy,quaint and sinister.

[TweenkPL]

I hardly find anything sinister in this part of video.

[exeuroweenie]

It's just that I had Hiroshima,Nagasaki,Three Mile Island and Chernobyl in the back of my mind.

[TweenkPL]

TMI created a huge decommissioning bill for the utility, but in the end nobody was even slightly harmed.

[northbeachfilms]

@exeuroweenie

well said. but i just LOVE this movie. it is a fabuloso.

[exeuroweenie]

@northbeachfilms I love it too,Stuff from back then is so retro cool without even trying.If you wanna see this incorporated in an early 80's music video,look up Raybeats Jack The Ripper on here.

[petestrat07]

At 1:40 I thought it was gonna be Bugs Bunny.

[SpaceTime4D]

@petestrat07 That's kind of funny, your idea. But Bugs Bunny is a trademarked character, and this was made by General Electric.

[quasarsumanth]

Education vid, interesting...

[ElRenaissance]

This is a wonderful and very educational yet entertaining video.

[socratus1]

Pauli wrote in 1924

" Each quantum state in the atom is not limited

of two electrons, but only of one electron"

It means in the atom can be only one single electron

The electron manages the atom

If the atom contains more than one electron

(for example two) this atom represents Siamese twins Save us God of having such atoms and cells

All living being begins its life from one singe atom, cell.

[BigBertlXXL]

Old school is cool!

[ChaosGIGA]

THATS SO . . . old school!

[mediapadTV]

no excuse for intro music like that lol interesting vid tho

[iruzanu85]

this kind of education can save human like our fuel and solve this formula E=MC2.

[SpaceTime4D]

@iruzanu85 Given the fact that C is constant, are you going to give me the value of M or E? I will solve for the other.

[TheCuged]

Do you have a second atom found inside the atom to lose?

[GodKillerAtheist]

its a good thing neutrons don't exist Just like evolution and gravity all lies from Satan!!!!! LOL...only on conservapedia =P

[99rhetbaboons]

If you think you understand this, you don't understand this.

[blink234234234]

shut up, faggot

[razor71927]

And you can't spell "incorrect".

[GodKillerAtheist]

Just like Evolution I don't believe in the atom. jkjk

Great video

[Crazeyfor67]

been wanting to see this again for years! Thanks so much

[killerz1230]

Haha ,

i love watching these typa old American documentaries =)

[namaoui]

great job to bring such a fundamental concept in one beautiful movie.thank you :)

[jinjerly]

Of course, just recently, the Titan 80-300 Cubed Microscope was installed, allowing scientists to actually see an atom.

[Bugstomper2]

This is dated, because electrons aren't really orbiting particles. They're both particles & waves. An atom consists of electron shells.

[SushiBand]

indeed.... but that was discovered in the 20's... why is a film made in the 50's ignoring that

[tomhsharky]

I've never seen a geiger counter that looks like that either...

[SpaceTime4D]

@tomhsharky It's a cartoon made 60 years ago. It's fairly obvious that the designs would have probably changed since then.

[skatinguptown]

Well, the nucleus of the atom is so dense, that electrons have some what of a gravitational orbit, but very little.

[Jensiebo]

M'kay

[SpaceTime4D]

@skatinguptown Yeah, at the atomic level, gravity is so weak, it is pretty much ignored. But we're still trying to fit gravity into the Standard Model. For the most part, electrons are held in orbit by electromagnetism.

[SpaceTime4D]

@Bugstomper2 It's 60 years old. What do you expect? The Bohr model was still accepted then. Quantum mechanics was a brand-new field then. Tell you what: learn animation, and make your own, current version. Maybe I'll do that, too. Someday.

[chris8702]

love the pride people had in science that long ago, these days know one really gives a damn, we just take it for granted.

[ohk321]

yeah, we learned to spell instead

[chris8702]

i dont get it?............

[XoxEm0xoXF]

love it... WISH EVERY KID CAN WATCH THIS.

[SpaceTime4D]

@XoxEm0xoXF Yeah, maybe when I enter middle school, I could maybe present this in science class or something. It serves as a sound introduction to nuclear energy, plus it's so darn fun to watch radium dance like there's no tomorrow and jump through his roof.

[SpaceTime4D]

@XoxEm0xoXF Yeah. I think others would find it funny to watch a crazy radium dance and jump through his house's roof in the middle of the night. I really need to show some of my classmates. If only YouTube wasn't blocked. Lots of old videos tend to be funny like this. Hurray for edutainment!

[anshulkamboj]

i hope i can get these videos wen i was kid... so damm easy to understand by a kid like a story...

[ReverendSyn]

04:34 - SOMEBODY GET THESE SPIDERS OFFA ME!!!

04:43 - Ow! My nads!

[03isaaaa]

we did this in physics...learning about nuclear bombs...livened up the lesson...momentarily

[bashibazouks77]

hah! my chem teacher showed us this video. 15 year olds

[panzarw]

maybe this cartoon is corny but it cleared things for me, i just want to make a simulator of atoms, like how it all began, you know 1 hydrogen is enough to creat all the other atoms only you need physics to do that, so if everything works then we dyscover everything about the atom world, if somethings missing then back to the micro world for searching.

[muffinman1]

thanks for sharing this!

[jatinsharma1989]

it is so good.............

[Montork]

coooool!

[tiver62]

So good lecture.

classical. and effective
