Tara Shears - Antimatter: Why the anti-world matters
ฝัง
- เผยแพร่เมื่อ 17 ต.ค. 2013
- Antimatter, an identical, oppositely charged version of normal matter, is one of the most mysterious substances in the Universe and very little of it survives today. Tara Shears examines the progress being made towards understanding this elusive version of matter, and explains the latest results from LHCb and elsewhere.

If I'll become a good scientist, then I would never forget how royal institution has sparked my curiosity and the knowledge it has given me . Thank you very much for making available these talks on TH-cam
You are our only hope. Become a great scientist and help us defeat these evil anti human beings.
Yawwwn ....
Ekalavya Rathore,
"If I BECAME..., I WOULD ..."
"If I BECOME..., I WILL ..."
Go for it and don’t let anyone discourage you👍
How is your journey coming along towards becoming a good scientist?
What an outstanding lecture.
I'm so blessed and privileged to have access to the world's information.
So grateful for these Royal Institute lectures.
Tara was an absolute pleasure to learn from. Thank you Tara!
The Lord Jesus Christ died for your sins, was buried and rose from the dead on the 3rd day according to the scriptures (The Gospel 1 Corinthians 15:1-4). If you believe in your heart that God rose Jesus Christ from the dead and confess with your mouth Jesus Christ is The Lord you will be saved (Romans 10) Go to a quiet place and ask the Lord to save you and forgive you from your sins - Believe on Jesus Christ and call out to Him before it's too late
Probably one of the best lectures I have ever seen. Not only does Tara have a truly excellent background as a physicist, she is arguably one of the best presenters of highly complex subject matter (no pun intended) I have come across.. Highly compelling and utterly fascinating.
It's incredible to think sc much strides in anti hydrogen are being achieved imagine the amount of weight that could be achieved harnessing this energy instead of chemical fuels
She also like the female version of Morgan Freeman... She could narrate the most complex science topic or someone making a cup of coffee and her voice would fit perfectly
Thank you for clarifying that it's not her looks.
Anyone else watching this in 2020? It may be old, but it is still an incredibly articulate presentation on Anti-Matter for anyone (like me) wanting to get a better feel for the subject.
No need for comment...res ipse loquitur.
Absolutely! I could go on all day about how articulate this talk is, but another thing to appreciate here is her conduct. She inspires me; I’ve not seen too many women in Physics in general. Her eloquence, style and presence just zone me in. A classy woman radiating her genius. This talk was wonderful.
Old?
Not many scientists go into the basics of the LHC as much.
@@animayvin _Res IPSA loquitur_ . For goodness sake l expect you've got a doctorate and can't spell. SHAME.
Now this was one brilliantly done lecture!
“You either discover, or you discover more!!...you can’t lose in particle physics” Brilliant!
You can still discover less.
no that's just PR
Actually it's 'Theorize and Theorize more'.
It's because particle physics is just a mess.
When I was a kid, I used to love watching the Royal Institution Xmas lectures on t.v. during the school holidays. I even got to go to a couple on school trips. I'm so glad that they're still going. I'm sure that they were an inspiration for TED talks
Icould listen to Dr.Shears talk for ever, her voice is like butter! great content.
@@garyha2650 She would say : " Of course you can my dear , but make sure you leave some room for daddy's car .Daddy would furious if he was forced to leave his car out on the driveway overnight " .
And now your through puberty?
I thought i was beyond physically cringing, then ya went and said that.
She’s my lecturer 😂
I personally dislike this goodly-hippie manner, since can't believe she speaks like this at home.
I am very very impressed with her capacity to interweave so many newly and different concepts and put them at the reach of our understanding...thanks to her...Tara Shears
thanks for letting us know about antimatter and the research progress behind it. Everyone in this world should appreciate this.
Why?
This woman has the most soothing voice I've ever heard! She literally sounds like the British voice on my MacBook. LOVE listening to you speak Ms. Tara Shears! Great job!
quit simping, take a cold shower and go outside.
I have never heard anyone speak English so beautifully! Not to mention her enthusiasm and great knowledge. Thank you!
How did anti-mater research become a niche field? I get the impression very few particle physicists have bothered with it. Go Tara!
I appreciate these Ri lectures. Unlike Ted Talks, they allow for a more complete picture to be presented, and the lecturers elaborate their subjects thoroughly for semi-lay audiences (like me).
One of the very best lectures on particle physics I have witnessed.
Freakin' LOVE these Royal Institution lectures!!!! They get the best and brightest to present complicated scientific topics in ways that normal folks can relate to and begin to understand. Also, you KNOW you're getting the best that science can offer: the credibility factor of the Royal Institution is Off The Charts!!
I really enjoyed this lecture, not only for it's high quality of scientific wisdom, but also for the passionate and enthusiastic attitude of Mrs. Shears. You really could feel that she loves what she's doing.
9:10 ... "The antimatter equivalent of the negatively charged electron is the positively charged proton."
She misspoke. She meant to say the positron, not the proton.
rogermwilcox hater
Both don't exist, man!
yep i cough that too. it is to see if i was awake, good job.
excuse me? we all make mistakes. i would think RogermMWilcox is helping those of us who arent't scientists not be confused. I am grateful.
@Samwisegamgee The Brave This verbal "typo" jumped out at me as well. She DID say "electron" and then erroneously said its antiparticle was a proton. Positrons are the simplest example of antimatter, and she got it wrong, - off to a bad start. A non-trivial mistake. At that point, only people already familiar with the subject matter understand what's being said, while anyone new to the topic and trying to learn is immediately lost, without knowing it. Well when you are up in front of a room giving a talk it is easy to make simple mistakes - no problem. I think this verbal typo should be acknowledged as the first thing in the text below the video, and in a little on-screen text "woops" note when she says it, like many other videos do. Sure everyone makes mistakes, and the best thing to do is explain them right away. That way, beginners get the right information, and experienced people are saved from stopping the video to comment, possibly then moving on and finding something else to do besides watch it anymore. OK I gotta go get a PET scan now. Kidding. If you get the joke you probably caught the error too. It makes me feel smart that I remember high-school physics! :)
What an excellent lecturer! Really intriguing stuff even if I don't fully understand it all. That's the sign of a good teacher, they can make you passionate about things you never knew you cared about
I could spend the day listening to this lady. Love her voice.
Pretty voice but she looks a little bit trans.
she should tell the truth she knows nothing its all a guessing game...
@@jackstewart5516 👍
The anti world is lgbt plus tax.
I couldn't stand the sound of this otherwise awesome lecture, the s is tearing my ears apart. She needed a different microphone, or at least a de-esser filter on the final video, because as it is, all I can hear iΣ ΣeriouΣly annoying eΣΣes in every word! It'Σ Σad :(
For the first time I've come to grasp the challenges that antimatter poses to our current understanding of nature. Very interesting how the existence of antimatter was deduced from Dirac's formula. Thanks for this amazing video.
This is BRILLIANT! I love how approachable and integral the exposition was. All my respect and admiration to Tara, wonderful role model for future scientists in general. Brilliant I say!!
excellent speaker and enthusiastic too , the lecture was very interesting and i am really impressed... thanks a lot...
When Tara describes it, it is magically easier to understand. Apart from being an amazing scientist she is amazing teacher. I think the musical quality of her narration has a lot to do with it.
Engin Atik Agreed (after having listened to other videos on the same topic). PhD from Cambridge
Similar accent as Jane Goodall also from Cambridge.
The accent/tone of her voice is helpful, but it's mostly the way she organizes the arc of the presentation and the structure of her sentences. Also the way that she helps us understand why something is important before explaining it to us. She really is an excellent communicator.
Thank you to Tara and The Royal Institution, that was a great presentation.
Brava, Tara Shears! Quantum theory nicely explained without shunting aside some layman's terms and analogies!
Tara Shears is an amazing presenter. Her voice is mellifluous and crystal clear. I hope we hear more from her.
I am no physicist, but this is one of the most fascinating lectures I have ever seen!
Tara Shears explains also in a few words quantum theory. The best description of quantum theory ever. Don't take me wrong, I do appreciate her explanation on antimatter. Thanks Tara.
Your Lecture is mega-elegant, and is very comprehensible. THANK YOU
Your Lecture is mega-elegant, and is very comprehensible. THANK YOU
My reading of Dirac's initial position on the reality of the "holes" in the spectrum of solutions was that they were not physical. He was naturally happy to change his interpretation when experimental evidence showed up supporting the existence of positrons.
This lecture is so good, I will listen to it twice. Excellence defined.
Thank you for such an understandable and and interesting look at the work you are involved. I can't help thinking "All is one"?
The RI should repost this as a ASMR video due to that smooth af voice !
She makes a little smacking sound from time to time that triggers ASMR.
This episode may be four years old, but that old boy Paul, nearly a century ago, had a good idea as to the key issues as to massive movements that push and pull on everything from our skin onto our bones. Well presented.
Such a delightful and cogent presentation ... it's even evolving, for me, into some sense. Thank you Tara Shears.
She has a great voice. And the lecture is very clear and well planned. Thank you!
What a soothing voice!
Thank you Tara, a greatly interesting update on the frontier of science. Please continue to keep us all informed. You'd be surprised what may come out of such communication.
Well, Dr Tara, that was so fantastic and let me tell you why. I dropped out of secondary school in year 10. My favorite subject was science. It was the only subject that I missed when I left. What you have just done is bridge the gap for me in a very clear and succinct manner. Really, nicely done. Thanks.
My chemistry teacher tried to convince me antimatter doesn't exist and made fun of me during class for quoting Lawrence Krauss on the subject.
At least we know better.
and at least you had a good teacher six years ago!
Your teacher should of known better . . . 🔬🔎🔭📡
Square like Cox.
@LUXAETERNA6603 - Even though I know but a fraction of a scintilla about science, I do know that no scientist can guarantee with absolute certainty ANYTHING. Findings are continually being challenged so that what is considered 99 percent fact today is the "next" day being wiped out and supplanted by new information. Trying to humiliate a student in front of their peers should be cause for termination.
Your matter-of-fact manner of making your comment suggests that your former idiotic teacher had absolutely no ill effect on your psyche--and that's a good thing--but no thanks to him or her.
@@Scathingly It's the philosophers that can't guarantee anything. Scientists definitely do guarantee things, they just don't guarantee as much as we would like.
@@Huntracony - I'm sorry, but what you say is simply not true. Scientific findings are not written in stone and MUST change as new information becomes available. That's how science evolves. I doubt that man will ever see the day when this evolution of science stops because it's been mastered. There are no guarantees in science --there are probabilities ranging from exceedingly high and then on down the line. Scientists challenge one another all the time.
Besides, you missed my main point; namely embarrassing a student particularly in front of his/her peers is a form of bullying. Why ever would a teacher want to stoop to such a level.
Finallly, you say that philosophers can't guarantee anything: I call that a no-brainer. Throw in religion and voila we are in total agreement.
Thank you for a very clear explanation of this subject.
Science talks too much & then it accuses religion of doing the same. No matter what we think about we have to speak about, & then it is carried out. The scientists get together & talk about an idea from the latest equations; however, it takes some one less gifted in mind that must carry out the idea by building the machines the scientists speak about & then publish their ideas that are made to do the things that scientists usually don't do; I.e. the hard labor. This creates an indirect link with the scientist that led to creating the atomic bomb by Oppenheimer to the utter astonishment of Einstein that Oppenheimer seized to sadly destroy populations rather than employ them. Apathy is the cause of any misinterpretation because it is diametrically opposed to real empathy, a trait that science still really lacks. Science is matter over minds while Reality is minds over matter. Uncle Matter & Anti Matter must choose wisely always!
This was great! So much information crammed into one talk. Not only that, but it was presented with just enough context to make it all valuable and easily understood. 👏🏻
I am watching it mid 2021 and just like previous poster, I am fascinated by this branch of physics even though I have no physics background. Thank you Royal institute
Excellent overview on antimatter and experiments characterizing the phenomenology of antimatter.
We need more people like Tara to promote science in this world.
+Alex Radu You're too late.
also, more of less people like you
Though I was looking to satisfaction for curiosity of science this woman adds an extra dimension . Fantastic preentation and an attractive personality I guess.
Scientists, do you mean? ^_^
Tool fan, eh? High five!
Tara is the woman who fell to Earth. She strikes me as a very sincere wholesome person and a woman with nothing to prove with her femininity. A true pleasure to hear her account of her endeavour on a level even a man can follow LOL.
Her voice is no nonthreatening. I'm far from being a scientist but I just liked listening to her enthusiasm / passion.
On top of it all, she has the smoothest voice ever. Tell-tale anti-matter:)
+Ivia Dables #hashtags #hashtags #evenmorefukinhashtags
ya that was more than fair roflmfao
This was brilliant... now I can say that I have a favorite physicist. Well done, Miss Shears.
Lovely presentation, with a bit of a poetic and theatrical dimension.
Wonderful, how you presented your presentation, well done indeed. Thank you very much.
Wonderful speaker in presence and voice. She reminds me of the lovely Tilda Swinton, but with Ph.D. in particle physics and superstar ambition for her scientific work.
very beautifully articulated
Excellent subject knowledge, excellent didactic ability, delivered in an enthusiastic way that is a pleasure to listen to and learn from. This made my day.
Personally, I think it's all relative. The 'matter' results from the equations describe 'matter' moving relative to 'space'. The 'anti-matter' results from the equations describe 'space' moving relative to 'matter'. This would explain the 'mirrored' description of anti-matter, and why we can't find it. I think it's a bit like describing the flow of electricity from two perspectives - Negative electrons flowing in one direction, or Positive 'holes' flowing in the other.
But I'm just a rookie at this stuff, and don't really know how to read the more complex equations, so I probably don't have a clue what I'm talking about...
Excellent.....as usual (at the RI). Dr. Shears reminds me of the female version of Dr. Brian Cox (same voice cadence).
her voice is amazing.. I think I've heard her voice on some documentaries.
Take a look at her page on the Liverpool website hep.ph.liv.ac.uk/~tara/ -- she has voiced videos and been interviewed a lot, which shows in how well she speaks. An amazing person.
She sounds like a commercial advertisement.
She sounds like the actress Tilda Swinton: th-cam.com/video/O-sFPLGwwYg/w-d-xo.html
Dr. Shears is very, very smart. She can speak for hours about things many of us don't understand.
She has also learned to breathe through her ears while she keeps speaking about things many of us don't understand.
Very, very funny.
This is popping up on my feed again. Probably the best RI lecture I have watched.
Such a pleasant voice. Thanks for the talk!
9:09
The anti-matter equivalent of the negatively charged electron is the positively charged [positron]
The anti-matter equivalent of the positively charged proton is the negatively charged anti-proton
Fixed
Thank you
One of the best explained discourses I have seen.Thanks.
A fascinating mind, a beautiful voice, and a gifted lecturer, that is science at its best. Thank you, professor, for this insight into your truly remarkable research.
She should do narration documentaries. Great voice
That's a bit like saying Babe Ruth had nice-shaped ears.
Fantastic presentation. There is a very amusing moment when she talks about Dan Browns Angels and Demons and how it claims that CERN is capable of storing anti-matter in battery driven containers that can be used to destroy the Vatican. She says they are nowhere near that capability. But then she says «But at least it's a start». That got me laughing so hard, I had to hit the pause button.
Vatican City, your days are numbered!
M Savage 》Your comment proves why presenting popular physics lectures without calculus creates a huge problem - there allways is a finite, non empty set of semiliterate religious lunatics who never miss the occasion to preach their lunacy. Try to wake up good man, the lady is talking plain PHYSICS!
M Savage lol shut up
I liked that part very very much.
Was amusing till you comprised the comedy dissecting the bloody joke.
Very good video RI, I really enjoyed watching that. Please more presentations like this!
Love the rhythm of her voice. It's engaging with a sense of wonder. I imagine she can read poetry very well. Thanks for the very interesting talk.
Very Intelligent I really like the information provided in this seminar Thank you.
John Hartman Not to mention that accent is awesome
I’m just going through this lecture and I believe when Tara says the electron has an anti-particle called the Proton, I think she means the positron or ant-electron.
Don’t suppose you know this for sure? Great point, if you do. She’s out here talking about proven science. And you are proving...?
yes, she obviously meant the positron…
@@jedgould5531 it is known even when she was giving the lecture. If you have ever publicly spoken, these slip ups ( proton-positron like) are quite common and they do nothing to project lack of information on the speaker's part.
If the matter and antimatter are perfectly equal, but not perfectly distributed, we should have pockets of matter and pockets of antimatter throughout the universe, even beyond what we consider the universe. There should be no need for one to be special over the other.
Fantastic presentation! Thank you very much for making and sharing this video.
Tara does a really good job at looking around and making eye contact with the whole audience, I think that's very considerate of this wonderful woman. And I really like her method of presentation.
Thank you very much Tara
I don't believe the anti-electron is a proton, as she stated. Perhaps it's a verbal typo, but the positron is the anti-electron. Not the same, even though charge seems to be close to the same. A positron would have a mass at least 1000 times less than a proton.
+mbrill77 Wasn't really giving her a hard time. Just noting. Except for the flub, I enjoyed it.
She mis-spoke at other times, twice describing the primitive cloud chamber as being filled with a "supersaturated liquid". In fact, cloud chambers are filled with rarefied air and water vapor in a supersaturated state.
After the 'proton' flub (actually, after she then described the antiparticle of the proton) there was a tell-tale pause. She could tell something hadn't gone right, but couldn't be sure what.
Tara is such a wonderful speaker and presenter. Easy flow of ideas, logical progression, and extremely clear!
One aspect that seems overlooked (or maybe I missed it) is that if the LHC (large hadron collider) occasionally produces antimatter particles of some kind, does that mean that the (nominal) protons which were accelerated were actually antimatter-antiprotons? Or is it implicit that the collision itself somehow occasionally produces antimatter?
bravo Tara...very elegant and simple explanations!
I was at this lecture!
Wow.
John Garner You’re so lucky!
👍
If you're a UK citizen, you're extremely lucky to have institutions like this.
Cool
The physical properties of antimatter is very interesting. A whole other relm of physical characteristics.
The achievements of modern particle experiments and measurements are nothing short of miraculous.
Wonderful lecture presented in an easy-to-understand way that shows us how much we don’t know about how the universe works.
She's so passionate about it. It's beautiful :)
Remember to hit the "like" and "antilike" buttons upon watching
Just don't hit them both at the same time.
@@rabbi120348 I did...my browser annihilated.
Why?
@@sonjak8265 Antimatter and matter annihilate when they meet. Antimatter, according to Dirac's original formulation, was a "hole" in a vast "sea" of negative-energy particles. The annihilation of the matter-antimatter pair occurs when the "matter" particle falls into the "hole" that we perceive as the antiparticle. The gap between the two is 2 x mc^2 (1 mc^2 for the particle and the other for the depth of the hole), and that is how much mass is annihilated and energy radiated away. This article may make it clearer: en.wikipedia.org/wiki/Antiparticle
Bob Rabinoff l
An excellent talk. Thanks very much, Dr. Shears.
Very very well made. I especially appreciate, that it wasn't dumbed down so low, that you couldn't even make out the science any more.
Thank you RI, for putting this online for everyone to watch :)
Fabulous.
A privilege to listen to this Lady.
It gives me Hope for our future!
@Radley2612Depends on your system of measurement, your intention to prove/disprove, your desired empirical outcome, and the data to which you refer?For starters.
@Radley2612Enlightenment. Education. Awareness. Understanding. Scientific comprehension. The usual Stuff, basically. ps: I don't debate with Creationists, just to give you the heads-up.
Excellent lecture, although I did not understand a lot of it.😊😊😊😊😊😊😊😊😊😊😊
All respect to Prof. Tara Shears and listen to you a great experience of my life. It is extraordinary.
what a great lecture and I love Tara's accent & presentation, very easy to listen to and understand
thank you for sharing all of these great presentations. Education should be free for anyone!
I like where you're headed, take me along if you need some people on the bandwagon.
Sadly even scientist lecturers need to pay their bills
Education is free for everyone... one can learn anything they want. If you can't self study then it is going to cost something. I think this seems fair.
It costs money to have your education certificated, but it costs nothing to learn, well it costs attention and time, but none the less, with a focused search you can find information on anything
I was wondering when we were going to make an electromagnet that could suspend nonmettalic matter by using the electron/proton spin. I want to see such a thing on a larger scale.
~ about 9:15, did you mean positively charged proton, or positively charged positron? However, a wonderful description of how intuition into the solution of Dirac’s equation explained so much by opening up the world into additional possibilities. Wonderfully presented :)
a new PHENOMENON for singular...otherwise what an excellent presentation in every way...
"We don't have enough antimatter to blow up the Vatican - But at least it's a start!" - Tara Shears
Reference to Angels and Demons.
Shouldn't we start with Mecca ?
Yes! What time exactly sure says this?
Think she did the math 😅
Amazing to see how amazed someone can be talking about anti-matter ^^
Thanks for sharing.
What is so amazing about anti matter
Quantum it's anti-boring
One of the best lecture that I have ever seen so far.
Amazing staff, I love this lectures .. it's ...
thanks for putting it on!!!
She is the female version of Brian Cox... They even talk the same and have the same "energy" to them. They even have the same interests. By the way, very interesting lecture.
I thought the same thing.
She's more competent
She is an anti-cox.
mart fart Do you mean a lesbian? :P
i want to speak authoritatively for an hour... maybe someday I'll have such authority on some matter someday that people will like to hear about
She didn't earn several advanced physics degrees because she wanted to give a lecture.
It takes approximately 10 years of focused dedication to master something... so the question is, are you putting in the effort? Or is it just a vanity project...
Absolutely fabulous lecture! *****
She has an amazingly smooth voice. I just wish she didn't make that high pitch sound at the end of most words.
Wonderful presentation. This was in 2013. Any updates on this topic?
A whole bunch of very sophisticated arguments... Interdimensional influencing and whatnot. Quantum entanglement being possibly correlated with gravity and the higgs, and why that is on a meta scale... Mostly numbers we can't quite calculate yet. Pretty controversial stuff. There are many physicists right now that can't seem to agree. But that's pretty normal according to what I have read.
