Celebrating 150 Years of the Periodic Table

Celebrating 150 Years of the Periodic Table


This is the 150th anniversary of
the periodic table as formulated by Dmitri Mendeleev and we at Fermilab have
brought together a number of scientists who are going to discuss what the
periodic table has meant for them and what it means in their everyday
scientific life now as well as its implications for the history and
development of science. I think the periodic table is a really important
part of science. So, I use the periodic table so back in school of course when I
was doing my chemistry and now I use it when I try to understand the behavior of
our detectors for example when we use the silicon detectors as the trackers in
collider physics. The periodic table represents an incredible level of
insight on the part of human beings towards the inner workings of the
universe around us. We were able to take these observations – counting,
measuring these elemental parts of the universe, and draw insight from that in
this really unique way and organize that insight in a way that allowed us to
predict elements that we weren’t even able to observe. And then later to
observe those and have those observations be correct. I try to imagine what it’s like
without having a periodic table. We’d just have a list of all of the
elements from one to whichever number were at at the time 116 or 118. There’d
be much less order in the elements and they’d make much less sense. For those of
us who don’t have perfect memories it helps to see things on a chart, to see
the organization, to draw the relationships between the different
parts. And so just in being able to know and to use the periodic table having the
chart makes it much more useful. The periodic table is based on chemical
characteristics, but also it’s behind so that the nuclei also have a similar
structure. And that’s reason why oxygen has the first the lightest element to have a
double magic number so that’s the reason why I like oxygen. I don’t even note
that I use periodic table while in fact that we do we all use it
one way to another. My favorite thing about the periodic table is that you get
not just a lot of technical information about the elements, you get some actual
piece of history about the elements. Because each element has a name, and the
people who discovered the elements generally get to name them. And most of
the elements – the vast majority were discovered in the last 300 years or so,
and so people were doing research finding the elements and then giving
names to them. And the names that they picked had some sort of significance to
them and a lot of the time you can get something about science history from
looking at the names. For example, helium. When people were doing studies of the
Sun they found some unusual spectral lines, and they did they deduced that
there was a new element up there and so they named it helium after Helios
the Greek Titan of the Sun. I think the periodic table is probably one of the
first forms of classification. It really set the playing field for things that we
build off of now. So in the past there you thought there was only four elements –
you know the whole earth, wind, fire thing. But now we know that there are elements and
we have it gives us a really good way of defining things and characterizing
things and we build off of that. My favorite element is something called
niobium. Niobium is hands-down the best super conductor of all the elements and
that’s why we use it in a lot of different applications here at Fermilab.
We use it in particle accelerators to accelerate and bend beams… I use the periodic table as a visual
for showing how science evolves. We use it in detectors, for astronomy … And the fun thing is to go from the most complex
current version of the periodic table to our simple little table which I call our
periodic table which shows the quarks and the leptons in the order that we
finally figured out that there is a symmetry and an order and a hierarchy
and so I make that link into complexity back into simplicity. We use it in our
quantum sensors … and in our development for quantum
computers because this material is such a good superconductor. It is element
number 41, if you were curious, and it’s named after Niobe who was daughter of
Tantalus in Greek mythology! The periodic table gave rise to wondering about
little quirks in the original version of the periodic table. When Mendeleev made
his table – he he was not the first but he was probably the most comprehensive of
the earlier earliest workers – I think he had 63 elements at his disposal and he
tried to array those in a way that made sense. The elements that he had were the
ones that chemists had discovered and so those are the ones that have chemistry
that make chemical compounds. So he missed out a whole set of important
elements like helium and neon and so on – the noble gases – because chemists had
never seen them. When it really comes to my you know consciousness that it’s
indeed kind of periodic table what I’m talking about, often comes with the
stories. So the periodic table is so rich because it has 118 elements, and to me,
especially when I talk to students, to school kids, I can talk about each of
these elements because behind them there is a rich story of discovery. Sometimes,
sometimes, you know, mistakes and so on and so forth. I think the periodic table
is is fantastic but there’s so much more beyond the periodic table that it’s not
everything. There’s lots of stuff to find and and that’s such a big
portion of what we do here. you

  1. 4:23 Oh no! The Higgs Boson is missing. I hope Fermi lab isn't too cynical to discredit a finding in CERN ?. Jokes aside, great video. Long time viewer, first-time commenter.

  2. One of Humanity's greatest achievements. An achievement worth celebrating. Keep up the good work Fermilab.

  3. The periodic table fascinates me in nutritional aspect. Note that all the nutritionally essential elements are grouped together, in almost serial order. Also the nutritionally competing elements reside side by side, like Copper and Zinc or Iron and Manganese.
    My favorite element is Cu, because Copper is the nutritional element that gives or brains a wisdom.
    Here is more about elements in nutrition: https://acu-cell.com/mr.html

  4. Fascinating topic, but kind of a boring video with people just talking in front of a periodic table. How about giving a short bio of Mendeleev and what he did, showing something about electron shells and why the table has this structure?

  5. im happy that people are recognizing IYPT. i find it super cool that something so seemingly simple can be so rich in information from a scientific and historical perspective and how useful it is if you know how to use it. happy international periodic table year everyone!

  6. Just learn this silly sentence and you have the first 20
    H He Li Be Bo C N O F Ne Na Mg Al Si P S Cl Ar K Ca
    ha heli bebocnof nenamgal sipsclarkca.
    learned it 35 years ago and I still remember that from my chemistry classes.

  7. Awesome the history of the organization of mass and energy with Gina Rameika really noting a further range where technically more order can be detailed with an expanded physicist periodic table that I am sure there is more to correlate with quantitative associations that isn't published already.

    I almost feel the physicists periodic tables were neglected in that further details and elaboration can be demonstrated with graphical representations of the quantitative data from the phenomena that we know as mass and energy… and I guess light also for a more dynamic representation?

    Man, that would be really awesome… an oscilloscope and spectrum analyzer overlay of information on a periodic table… including with a physicist periodic table with isotopes maybe for at least the half life representation if not the whole lifecycle. Yeah, that would be totally awesome and maybe can be developed into an LTSpice like tool for physicists and physical chemists! I think there can be expansion also into the inorganic and organic molecules also to further utilize the spectroscopic data culminated since the history of intellectual thinking decided quantitative analysis is OK. Not everyone will get busted for whatever they were compounding and concealing. ;-|)

    Let us not forget the geologists periodic tables also as those are interesting and detail a history also in regards to observations of phenomena and categorization of the elements at least… even though the elementary particles are so neglected until recently. Sad actually, I feel the elementary particles and forces are a victim of negligent abuse.

    Finally, what would be totally awesome being the reaction of living systems kind of periodic table visionary advocate… promoting the periodic table of the universe with the range of the smallest and weakest forces to the largest and most powerful known… even if sections will need tables of their own. That would be most excellent as an inspector general official of the universe.

  8. I wonder a lot what we may find on the moon in ways of alloys, wishing there's enough of less common elements or enough of something new to do so of course. Saying that, as shipping a foundry etc will be cheaper than any other rock for a while. Leave a few thousand square miles to crash asteroids into now and then.

  9. You forgot to include content from the worlds most eminent chemist of the periodic videos channel. The truly magnificent and world famous Professor Sir Martyn Poliakoff of Nottingham University England!!

  10. Gotta love hate relationship with the PT. In early 60's our chem class was forced to memorize the thing. Didn't make sense to me, it was a reference after all, plastered on every science class wall. Got to admit though, it came in handy in college. Still hate it.

  11. Hello 6 49 66! We thank you for being the best. Looking forward to seeing you when we come back from 16 8 92 90 95 68 53 20

  12. Why ladies are included in this video, it (period table) was invented by Russian chemist Kroneker's Delton

  13. I have a question. I was hoping you could answer it:

    It's a modified twin paradox. Most explanations of it rely on the fact that the moving twin comprises two reference frames, but I can think of a case where it's only one.

    The twin goes into space at some speed v. After passing a planet a distance L from earth (with respect to the earthman), he holds up a sign large enough that earthman can see it which displays the time it took. At the same time (L/v seconds according to earthman), earthman holds up a sign large enough for rocketman to see which displays his time. How is this resolved?

  14. I couldn't find a revealling answer. Maybe there's not. The "new" periodic table just shows lack of understanding of the actual periodic table.

  15. I heartily recommend the Periodic Videos channel from the University of Nottingham featuring Pr Martyn Poliakoff. https://www.youtube.com/user/periodicvideos . Especially the latest describing the history of its evolution: https://youtu.be/83RSwczyyRY
    All the elements described and commented! Interviews with scientists that discovered the most recent elements (like Yuri Oganessian). And especially lots of experiments with explosions! ?

  16. Strange is the fact that birth of the Periodic Table coincides with the birth year of Mahatma Gandhi! Does it convey some message to the world of the Scientists that emphasises more on the material aspect of the Universe than its spiritual significance?

  17. What's your favourite element? Mine is gold, not because it is valuable, but because it is so inert and beautiful.

  18. Thank you for your great educational videos. I would love to see a video about Faraday cages and specifically how mesh size relate to shielding ability.

  19. What does precession have to do with keeping a ship that's much bigger than the gyroscope stable? Or a rotating bullet not blown off course? My favorite gravity probe B changing direction because of Frame Dragging?

  20. Does anyone realize that the 1-st chance of life to begin & evolve has started only 7 billions of yrs ago. Before that heavy elements (necessary for biology) hasn't been created yet. I'm talking about star's production of all elements, heavier than iron.

  21. We need to use a particle collider to detect the secrets of cosmic expansion
    Primary particles such as quarks, electrons and gallons must be destroyed
    In order to find the cosmic expansion boson
    The primary particles consist of cosmic expansion boson
    The cosmic expansion boson is the unification boson between the forces of quantum mechanics and the relative theory of the German scientist Albert Einstein
    For this reason the particle collider force must be developed to monitor the cosmic expansion boson
    Microscopic monitoring devices must be developed to detect the smallest thing in the universe
