Catch our list of Nobel Prize videos from over the years: @t
I couldn't concentrate on the video. I was staring at the void around Prof. Poliakoff's head.
I know, right?!
They literally just revolutionized microscopy. This is amazing.
well, all the inventions that changed weapons, from a stick in the stone age to an atom bomb now "just revolutionized hunting"
*****
What are you hunting with fission bombs?
The Nobel prize is like the Oscars of science. Except the winners are actually deserving of the prize.
Wow this such a simple principle compared to an electron microscope. Biology is going to make a HUGE jump forward with this discovery, those three really deserve their Nobel Prize
Maybe we'll see DNA in process or maybe even molecules or atoms. Is sub-atomic and plank length too much to ask?
Emperor Palpatine
Sub-atomic is not possible with these methods as they only work with fluorescence.
Single molecules is possible as you can get resolutions of ~10 nm with this.
Emperor Palpatine No, these techniques simply localize a fluorescent emitter in space. You don't actually image anything directly. The resolution is further limited by the size of the fluorophore. The GFP protein is about 4 x 2.5 nm in size, which puts a lower limit to the resolution of what you can localize with it. The laser-based technique is higher resolution since it can use regular non-biological fluorescent labels on the order of 1nm or so in size.
Qatharsys I mean with microscopes in general.
Has professor Martyn Poliakoff won a Nobel Prize yet? He and Brady should win one for their work on promoting chemistry to the masses.
SuperToFue I don't think that is a category, but thanks! ;) we did get to hold a medal... Periodicvideos gets a Nobel Prize
That's really cool :) Thanks for sharing!
What happened to the professors hair?
Was he on vacation and mistaken for a sheep?
No, they had to inspect all of it under an electron microscope. Watch the video before you post a comment!
xXjazzpiXx what? that videos was like 5months ago.......
NeATaNDtURdy More like four years.
The real question here is what happened to _your_ hair, baldie.
chemistrycounts You don't get jokes, do you?
Sorry for the off-topic, but finding your videos is the best thing happened to me in who knows how long. You explain yourself really eloquently and you radiate honesty and modesty.
Thank you.
and here I was thinking you were going to talk about the blue LED, I agree with your statement that they got it the wrong way around.
The laureates within the different scientific branches aren't chosen by the same committee.
If you would like a video on that, go to Sixty Symbols:
Blue LEDs and Nobel Prize - Sixty Symbols
Professor Poliakoff has the capacity of explaining things so well it sounds not just simple but almost obvious.
Its like the 2-photon effect (2 photon microscopy using a Laser scanning microsocpe) .using an IR laser that will only let fluorescence happen at the focal point as if you were using a higher energy single photon), then you can mark regions in a cell with proteins and then you can image those regions without getting interference from other regions in the cell.
you can also use several markers to get more information
Give the Professor a Nobel prize for being my favourite person on the planet, legend!
similar solution is applicable to increase digital storage space on CD's - overlapping lasers on separate wavelengths to R/W data at a size smaller than the wavelength of the laser being used to do so. so clever to see that this same method of "shrinking" the practical size of a wavelength of light is applicable in such a wildly different situation!
Nice new hair cut! I will have a hair cut like this professor!!
BRASIL LOVES YOU PERIODIC TABLE
I feel like I've heard of this technology before today, but having to do with compact discs. Some scientists discovered that if you use two lasers in a specific way, you can make CD's that hold a great deal more information that the common method. I wonder if these things are connected?
Clear and very useful, i'll show this video to my students.
This guy is so smart and yet he's humble enough to say that he doens't fully understand some things. Thanks them parentes for making him, cause he's awesome.
Considering Gore and Obama have been awarded prizes I don't put any stock in them nor do I pay attention to them anymore. The Nobel Committee has zero credibility.
It's not as if they weren't worthy of a Nobel. But nonetheless your point still stands. Giving Gore and Obama a Peace Prize was ridiculous considering the humanitarian work that many others do.
The different awards are managed by different committees. The scientific awards are usually not too terrible. (though they have made some questionable calls) The Nobel Peace prize is kind of a joke these days, sadly.
I know Americans have kind of an undeservedly bad rep when it comes to geography but you mixing up Norway and Sweden .... not helping.
considering they didn't gave prof martyn poliakof the nobel prize of chemistry, they have zero credibility.
I'm sorry you didn't win Professor. I was rooting for you.
Hi Martin This may be an odd sort of message but Your such a nice guy and so knowledgeable ETC. I see it is a great honour and privilege being subscribed to you.
When I was about 8 my friend had a chemistry set with about 12 chemicals, a couple of test tubes a rack and the obligatory litmus strips, well nothing really seemed to work or do much so I decided to go down the electronic route so I ended up being an electromechanical engineer and the nearest I get to chemicals now is isopropnal lol
You might want to redo that explanation of STED and include stimulated emission (the red laser beam's profile - at least originally - was "donut shaped" so that the center would not be depleted).
i think your great prof. I miss school, I know have nothing to do
The description of Hell's approach (STED) isn't really correct.
*That tie...*
Laser Tweezers made of laser light to hold and control the shape of tiny droplets of liquid.
Lasers to mutate the surfaces of materials to change their properties.
Measuring gravitational variation over time, such as waves, by laser phase changes over time over a fixed distance.
And now interfering frequencies (colour etc...) of lasers on a single point, presumably being careful with phase and distance too, to sharpen the point that is lit, to build higher resolution microscope cameras.
I wish I'd had Professor Martyn as my chemistry teacher when I was at school
Epic video!
it's like a mix between biology / chemistry / physics
if the professor doesn't understand it, i'm not even trying to.
Outside of biologi would there be any advantage to this over electron microscopes?
My understanding of this technique is a little different to the explanation given here. Again, two lasers are used. The first laser energises the sample so that it will give off fluorescence at some non-deterministic time in the future (probably nano or milliseconds in the future). I believe the first laser can be of perhaps any wavelength so long as it transmits enough energy to sufficiently energise the sample. The second laser is then a tuned laser to stimulate emission of the sample immediately.
So the first laser energises it to cause the sample to fluoresce at some later time, but the second laser causes the sample to fluoresce immediately. i.e. it's "stimulated emission".
The catch is, there is a small hole in the 2nd laser. Something very small is obstructing the beam in the middle, which means that all atoms/molecules in the samples will immediately fluoresce EXCEPT the part that's not hit by the 2nd laser due to the hole in the beam. That section of the sample will then fluoresce at a slightly later time, and the system uses that information to build up an image.
By increasing the power of the 2nd laser and decreasing the surface area of the obstruction, they can, in principle, get arbitrarily fine resolutions. The catch is that as the energy of the laser gets higher, you eventually vaporise your sample.
Having said all that, I understand there were 2 related but different methods produced for this Nobel prize, so perhaps the Professor is talking about one method and I'm talking about the other.
Hey Martyn, do us a favor: Go win a Nobel Prize of your own so you can keep making more videos.
I really like periodic table of videos.
7:02 I completely agree with the professor on this one. When I first saw the nobel prize listings I though 'what the hell'.
My first year studying chemistry in Göttingen, our professor gets the nobel price. coincidence? i think not
i bet he goes crazy in the dog toy isle at a store. Ive seen so many dog toys in these videos but i love them
Prof. Poliakoff is so cool
This man is the human incarnation of of the field of chemistry itself.
I agree with the professor at the end with this being physics, and the physics being chemistry.
Professor what have you done to your hair???
Thumbs up for the tie!
I liked ure hair the way it was before, it had alot more caracter and personality!
In the end it doesn't matter what name you give your field of research as long as you make great discoveries.
Try visiting Hawaii to give a lecture to my Adv./AP Chemistry class :)
You trick me! I thought you would talk about the 3 scientist that won the price for "the blue LED" stuff!
that was the nobel price for physics i believe
"This is your last chance. After this, there is no turning back. You take the blue LED-the story ends, you turn the microscope in your lab and believe whatever you want to believe. You take the red LED too -you stay in lab, and the microscope will show you how deep the rabbit hole goes. Remember: all I'm offering is the truth. Nothing more."
Chemical Morpheus
I love you SCIENCE and all your branches.
awesome
Why doesn't any body use the professor's name?
Nice tie, cool science
you are making all these videos and I really appreciate them they are all very cool BUT
PLEASE update the element videos.....
I mean, it's periodicvideos... we can't even see all elements! yesterday I was watching Lanthanum video for example and we don't even get to see a sample... yet you have made hundreds of other videos about other things that are not elements. and despite appreciating those I feel like it's lacking a lot by not having much information about not so known elements :(
You are right. I agree!!!
Ivory vines
do you serious believe a 1min video is the same as 15min one with several demonstrations and interviews?
I can't believe that the Nobel prize is going to Hell...
the prof as a new hair cut
I don't see the professor disguising himself as a new hair cut anywhere in this video.
Dan Wipper Yeah, I think he knows that. But the point he was trying to make was how unclear the guy's statement was. So instead of saying:"the prof as a new hair cut", he would've said something like:"the prof with a new hair cut".
John Hilbert It's just a small typo lol.
has*
***** Oh, ok.
I would beg to differ with the Academy on the prize for Chemistry going to physics and biology, essentially. Considering the great importance that green chemistry is to the sustainability of life on Earth, someone or group doing this kind of work should have gotten the prize.
Let us predict Nobel Prizes 2020
I thought that Periodic Table of Videos won the 2014 Nobel Prize in Chemistry......
Nice.
Haha. I can see how you thought that,🔬
When I saw the title of the video, I thought "Oh? They won?"
i live in the city where one of the nobel price winners works!!! :D
Funny though, the physics prize was awarded to those who had a direct commercial application and the chemistry prize went to those whose motivations were leaning more toward pure science. Usually the other way around, isn't it?
Physics is before chemistry...Physics is the study of everything.
Who wants to finance me to invent a television whose picture is generated by fluorescent proteins?
Илья Найдов
So, kickstarter it is then...
At 5:01 the prof mispronounces Betzig and it sounds like breadstick 😂😂😂😂😂😂😂😂
Many new things about biology will be discovered due to this advancement.
I thought I was the only one who thinks something unusual is going on with Professor's hair. But when I scroll down the comments... unless everyone made the same mistake, I don't seem to be very wrong :P
Nice new glasses.
I've always fantasized about owning an electron microscope!!
btw what is that spinning around, in the reflection just over the profs right shoulder? A CD on a piece of string!
It's a reflection on the LCD screen. Definitely something spinning on a string in the window.
you have strange fantasies...
6:21 Look, it's a bird!
Please include more photos or video clips in the video...... mere talking is boring...
engineers won the physics Nobel prize, physicists BTFO
Engineering FTW!
hatbat1234
Honestly.... I'm studying physics but I wish I had the time to actually study Engineering after I'm done with physics. Both are very important. And those two disciplines need each other.
Imagine what one could do after having mastered both!!
***** Yes, both are excellent
careers and help to change and better understand our world.
If you take up engineering, taking one that you like the most. If you like mathematics and chemistry, choose electronic or electric. If you like programing or more mechanical sides, choose mechatronic or systems.
Trust me, as an engineer, you'll go places most people don't ever think they'll ever go. The last project I had, was very large; involved flying stuff, 'cough' 2009 'cough'.
If you're extremely well on what you do, your university can call you right up and ask you to be a professor. I'm teaching calculus, differentials/ integral and lineal algebra.
hatbat1234
Wow that sounds really nice.
Seems like you made the right choice!
Congrats to that!
Xaurum Planck
You could just have a civilised discussion with him, instead of bashing him you know?
The thing is... physicists obviously have a deeper physical knowledge than engineers.
But we can't build most of the stuff.
Engineers need to do that.
Which is why I said, I'd love to study both.
You know... inventing something and then building it yourself.
Wait, when did the professor get new glasses?
The hairdo does the professor at least 10 years younger :D
1:58 In other words the electron beams in an electron microscope are like americans post 9/11
HE GOT A HAIRCUT.
NOOOOOOOOOOOOOOOoooooooooooooo
Oh so that's what it is.
oh what the heck you cut your hair prof!!!
What if you make a camera that is smaller than a living cell.
5:00 breadstick
You had your haircut :( But great video
Has the Prof. had a haircut? Please say no. But the microscope thing is pretty cool either way. Although, as the Prof. said, I would have swapped the physics and chemistry awards.
Impossible. Poliakof had a haircut...
NOOOO THE HAIR
his hand gestures are funny
WHAT?? Cool cool cool COOL.
2024❤
3-4- Quantum-Physical-biochemical-Technological Tech = SymmetricalTech**.. Noble prize 2008 okay we get it. More experiments, more questions, more scientifical conclusion(s).
New glasses? :-D
Nice glasses.
I am always disappointed when I open a new Periodic Video and the professor has had a haircut.
I hope the same principle does not apply to the professor's hair as is reputed to have applied Samson's.
nice haircut prof :)
😈I love his hair. It is his trademark.
2 Of the winners live in the USA, but all 3 have german last names :D
and none of them deserves it.
all the three scientits names sound german (jewish)
So????
They're Canadian and German.
*throws bag of attention*
I am not judging. Just came to mind...
The first one is part Romanian, part German
Like the zinger(s) at the Nobel committees by the prof.
funny scientist ^^
first blocker.
First.
What are you going to do now?
New haircut
Everything's done with lasers these days
nice haircut
biology is chemistry and chemistry is physics
Yes, I would add biology is applied Chemistry (by nature) and Chemistry is applied physics (by humans).
Who gave the Swedish academy of science the rights to give prices anyway? Seems to me that they are taking advantages of the work of real scientists to raise their profile... Dynamite?
I always viewed chemistry as wet physics, and I bet the Swedish Academy figured the same.
PROFESSOR!!!! YOUR HAIR IS MISSING!!!!!
