Have you ever seen an atom?

Have you ever seen at atom? Seeing as everything is made of them, you have. But have you ever seen one on its own? Over time, microscopes have
become more and more powerful, allowing us to see deeper into
the world of the ultra-small. Traditional light microscopes can be
used to see things like these onion cells and the structures within them as they
divide, pulling apart their chromosomes. But scientists have come up with a whole host
of clever methods to observe far smaller things. Using beams of electrons instead of light, we can
generate detailed images of chromosomes themselves. Recently, groups of scientists
around the world are becoming able to see materials at the most
fundamental scale – the atomic. One group from the University of California in Los
Angeles have been getting up close and personal with nanoparticles of platinum,
just a few nanometres across. Each of the tiny dots you can see here
are actually individual platinum atoms. But researchers didn’t stop
at a two-dimensional picture. By imaging over 100 slices of the
nanoparticle at different angles then removing the
noise with a special filter, they were able to map the location
of almost every atom. The information was used to create
a three-dimensional reconstruction of the whole particle
in unprecedented detail. It may look blurry, but this particle is
estimated to contain over 27,000 atoms and so, like flies in a swarm,
they appear to merge together. Every so often, though, we see the platinum’s atomic
structure align, granting us a moment of clarity. This technique is being used to analyse tiny irregularities
in the structure of the particle called dislocations. Dislocations are subtle, like the misalignment of
the green and red layers of atoms in this particle. But nonetheless, they can significantly
change the properties of materials, with effects ranging from a change in the
efficiency of LEDs to the strength of metal alloys. Three-dimensional atomic-scale imaging
like this is bettering our understanding of the structure of materials on
this truly fundamental scale.

  1. Its a bit like NASA's CGI/Photo-Shopped earth pictures..All I see in this video is what looks like CGI….There's no proof of anything..We might as well zoom in on the wallpaper on our walls to see creases and fibres and take a pic of it..and say: ~ "There you are particles/atoms etc"..its like..~ "And??…."

  2. These are nothing new. Arabs in 7th century had knowledge about all these.. Something you find out in future also known to them.

  3. Я часто думал о том, как в моём мозге могли визуализироваться атомы, частицы энергии, то, что происходит внутри атомов, как вселенная творит себя. Теперь я знаю как это происходит. Теперь я знаю и понимаю весь процесс визуализации 🙂

  4. Who watching this video from india .Plz reply me. And also clik a like .So nice video and very useful for students .Thanks plz make more videos like this .

  5. It seem like the atom has a electron-shell. The "color" of the surface of the electron-shell seems like "homogenous" per time which indicates that the electrons are there at "every point" on the electron-shell per time. No doubt that electrons are revolving round the nucleus at very high speed, to have electrons at every point on the electron-shell which implies that there are many electrons are revolving round the nucleus. In my research, we reckon that the absolute charge of 20 electrons is equal to the one of a proton. Why? The existence of so many types of super acids, mineral acids and weak acids suggest that the absolute charge of an electron is much weaker than the one of a proton. If acidity is caused by the single protons, then all of them should be exactly identical to one another therefore all different acids should have similar causticity. Wrong. Therefore the absolute charge of an electron should be much weaker than the one of a proton. Absolute charge of 20 electrons is equal to the one of a proton will give rise to many varieties of "single" proton each with different number of electrons within their electron-shell. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory – Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.

  6. Yes ı see. Behind to my house yes fresh fruite juice shop he put in the side honey,banana,stawberry,walnut,nuts and milk after he mixed all this in blender its name is ATOM… What enteresting i dont understand 🤔

  7. We can simply calculate no. Of atoms or molecules in any object.
    1) find the composition of object, elements that it contains
    2) percentage of all these elements and then calculate their exact masses present in that object
    3) use their molecular mass and avagadro's constant ratio to calculate no. Of atoms of each element present in that object.
    4) add all the calculated data hence you'll find the approximated no. Of atoms/molecules present in that particular object.

  8. Sve te gluposti koje vi istrazujete su netacne. Upamtite ali bas dobro sve se desava voljom svemocnog boga alaha. Ja ne zelim ni da sam poznat na ovom svijetu I nikakve me titule ne interesuju.zelim samo jednom bogu alahu da se mollim I sto vise dobrih djela da uradim ne da bi me vi hvalili jer to je mnogo lose.dovoljno mi je da mi bog alah zna. sto bi ste rekli da ste u blizini I jacini eksplozije od 10 mega tona?

  9. Porque mierda no dejan activado la opción de subtítulos en español???….es ciencia!!!…es una obligacion dejar activado los subtítulos en todos los idiomas posibles… 🙁
