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
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 RUclips
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
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!
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).
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
@@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 " .
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.
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.
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.
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
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!!
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 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 :(
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.
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.
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.
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!!
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.
@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! :)
Though I was looking to satisfaction for curiosity of science this woman adds an extra dimension . Fantastic preentation and an attractive personality I guess.
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.
Thanks for sharing, this scientist really makes me excited about things that most have a hard time explaining with this much enthusiasm and clarity. Excellent speaker.
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.
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.
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.
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.
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?
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
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
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.
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.
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. 👏🏻
~ 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 :)
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
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.
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.
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 :)
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!
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.
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.
@@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.
I have a question. If matter and antimatter annihilate each other, how was Carl Anderson able to see the particle traverse his (liquid filled) apparatus? This would mean that a positron's perception of our world is not that much different than the space it just traveled through. There must be a lot of positrons bombarding us for one to reach Anderson's device?
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.
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!
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.
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.
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.
It would be very helpful if you enable - at least - the captions on the settings of the video, in that way the auto generated captions can help people like me to have a better understanding.
Is it possible that there's equal amount of matter and antimatter in the universe but the inflation period caused the isolation of places where one or the other was in higher amounts, and then the speed of expansion prevented these regions from ever interacting again? That would mean we live in one of possibly many isolated regions of the universe, in this particular one there was more matter than antimatter.
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.
I bet you have an hour of your life to spare where you could just sit down and enjoy this. You're really missing out. The presentation is just as inspiring as the content.
@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.
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.
I love listening to her speak, even if I have no idea what she's talking about. She has so much wonderful information in her brain. It's amazing. I'm wondering if I have the corresponding anti-matter in MY brain. How would we test this? I'm thinking that we would touch our foreheads together and if annihilation happens, then I did have THE corresponding anti-matter in MY head. If no annihilation happens, that means I can continue to listen to the brilliance that flows from her in her wonderful accent and lovely way of speaking. So lovely.
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.
@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.
Great job Tara. I remember a time when there was fear that experiments at the LHC would be the beginnings of a collision between matter and antimatter that would set off a chain effect resulting in the cataclysmic destruction of the Earth.
@@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
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.
Tara, your predicament in this presentation and that you, Sabine and Lee made on the Anti-Universe is the same. The problem is due to a misconception that in the beginning matter and anti-matter are similar and should annihilate as per the Dirac"s Theory on anti-matter. Based on that incorrect initial condition, the contemporary anti-matter Theory and the Standard Model of physics premised on this misconception fall flat. My recently proposed Anti-matter Theory attempts to right things and should be expiditedly be considering in rewriting the Standard Model and to enable science to move forward in this 21st Century, so I think!
At 9:12 she says that the antimatter equivalent of an electron is a proton, which is not the case, if I understand things right, but a positron. I think this was just a "brain fart". She obviously knows what the deal is and overall is doing a good job of presenting. I wish I could do half as well. It's interesting though because there is a slight hesitation right after the mistake because her brain knows she is saying "proton" too many times.
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

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!
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.
Thank you for such an understandable and and interesting look at the work you are involved. I can't help thinking "All is one"?
some pictures are not shown.the cameraman has to be properly directed.we may be missing some matters.
She's so passionate about it. It's beautiful :)
Lovely presentation, with a bit of a poetic and theatrical dimension.
Excellent.....as usual (at the RI). Dr. Shears reminds me of the female version of Dr. Brian Cox (same voice cadence).
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.
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.
I have a question. If matter and antimatter annihilate each other, how was Carl Anderson able to see the particle traverse his (liquid filled) apparatus? This would mean that a positron's perception of our world is not that much different than the space it just traveled through. There must be a lot of positrons bombarding us for one to reach Anderson's device?
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.
Wonderful lecture presented in an easy-to-understand way that shows us how much we don’t know about how the universe works.
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.
She should give a lecture on how to give a lecture she is so good.
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.
It would be very helpful if you enable - at least - the captions on the settings of the video, in that way the auto generated captions can help people like me to have a better understanding.
The physical properties of antimatter is very interesting. A whole other relm of physical characteristics.
Is it possible that there's equal amount of matter and antimatter in the universe but the inflation period caused the isolation of places where one or the other was in higher amounts, and then the speed of expansion prevented these regions from ever interacting again? That would mean we live in one of possibly many isolated regions of the universe, in this particular one there was more matter than antimatter.
good one Tomaszs.
Very Intelligent I really like the information provided in this seminar Thank you.
John Hartman Not to mention that accent is awesome
An excellent talk. Thanks very much, Dr. Shears.
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.
I bet you have an hour of your life to spare where you could just sit down and enjoy this. You're really missing out. The presentation is just as inspiring as the content.
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.
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.
She has an amazingly smooth voice. I just wish she didn't make that high pitch sound at the end of most words.
I love listening to her speak, even if I have no idea what she's talking about. She has so much wonderful information in her brain. It's amazing. I'm wondering if I have the corresponding anti-matter in MY brain. How would we test this? I'm thinking that we would touch our foreheads together and if annihilation happens, then I did have THE corresponding anti-matter in MY head. If no annihilation happens, that means I can continue to listen to the brilliance that flows from her in her wonderful accent and lovely way of speaking. So lovely.
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.
One of the best explained discourses I have seen.Thanks.
Great job Tara. I remember a time when there was fear that experiments at the LHC would be the beginnings of a collision between matter and antimatter that would set off a chain effect resulting in the cataclysmic destruction of the Earth.
Part of CERN blew up 3 years ago. Wait for THEM to expand into the inertial plane. Where the Universe perturbated from with sound/cymatics.
Brilliant exposition by Professor Shears. Brilliant.
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

what a great lecture and I love Tara's accent & presentation, very easy to listen to and understand
Excellent lecture, although I did not understand a lot of it.😊😊😊😊😊😊😊😊😊😊😊
I could listen to Tara Shears talk her sciencey science all day, every day.
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
Tara, your predicament in this presentation and that you, Sabine and Lee made on the Anti-Universe is the same.
The problem is due to a misconception that in the beginning matter and anti-matter are similar and should annihilate as per the Dirac"s Theory on anti-matter. Based on that incorrect initial condition, the contemporary anti-matter Theory and the Standard Model of physics premised on this misconception fall flat.
My recently proposed Anti-matter Theory attempts to right things and should be expiditedly be considering in rewriting the Standard Model and to enable science to move forward in this 21st Century, so I think!
very beautifully articulated
At 9:12 she says that the antimatter equivalent of an electron is a proton, which is not the case, if I understand things right, but a positron. I think this was just a "brain fart". She obviously knows what the deal is and overall is doing a good job of presenting. I wish I could do half as well.
It's interesting though because there is a slight hesitation right after the mistake because her brain knows she is saying "proton" too many times.
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
a new PHENOMENON for singular...otherwise what an excellent presentation in every way...
My God this woman's voice should be used in documentaries and - space video games, its so excellent!!
