It is incredible how easy this man explains such complicated mater. He does all this with a permanente smile on his face, using simple words and a humble approach. Unlike the man who introduced him, he is very humble, and just a wonderful human being.
It's amazing that he talks about Higgs particle and says that they use it in equations even though it might not even exist but just a year later they confirmed it's existence! Made me very happy.
They could tell you anything and you would believe it, wait till you find out it’s all nonsense, will you be able to fight the cognitive dissonance I know you’re going to experience, will you be able to be honest with yourself with an open mind when presented with evidence and an obvious proof and just obvious common sense, the real world laughs in the faces of these physicists of self proclaimed know it all’s Science isn’t what Brian says it is, there’s not one practical demonstration using tangible substances for ANY of the claims that the earth is a spinning ball in a vacuum, even Einstein said there’s not one observational experiment that can show the earth is in motion, water doesn’t conform to the exterior of shapes and objects, water has to be contained, once contained the surface will always be a level line, water is used in construction to find plumb and level, water doesn’t have the capability to support sheer stress, it’s called the horizon for a reason, horizontal, and the oceans are known as sea level, level doesn’t mean a curved line, in the real world level is a straight line, no experiment can show a gas pressure like our atmosphere existing next to a vacuum without equilibrium taking place, both have to be contained and can only exist side by side whilst both are contained, the globe is being shown for the scam it is
. ... or just look a the earths shadow on the moon ...lol . Although I do believe most or all theories held today will be disproven 100 years from now ... .
He is really good at laying difficult and complex theories/ concepts/ facts in simple and down-to-earth language. Hopefully I can meet him when I come to Manchester to study the coming year!
there's no better inspiration in the universe to young aspiring physicists than Prof Brian Cox.One of my all time heros.Had i been watching this at a young age, i'd certainly be pursuing a career in the fascinating field of science.
At 41:00 Dr. Cox talks about a particle that is theorized to exist in the Higgs field, and in the spirit of Feynman they'd have to go and look for it, in order for their theory to hold. As we now know, about a year later, Cox and all the amazing scientists at CERN discovered just that - the Higgs particle, effectively proving that the science was solid all along.
I’ve finished A-level Physics and will begin my MPhys in September, but I thought I’d put this on to hear Brian talk - whether it’s tailored towards GCSE kids or 4th year quantum physics students I find his explanations riveting. 40:58 to 41:14 in particular really does make me smile when you realise this lecture was a year before CERN first witnessed the Higgs boson.
The idea that someone could work out that time slows down relative to speed by just sitting there and thinking about 2 mirrors and light bouncing between them is really mind bending stuff. I get the sense that Brian himself is in awe of Einsteins genius.
I've always had a problem with that diagram. As soon as the mirrors move, the light bounces away and you can no longer measure it between the mirrors. You know if you shine a light at a mirror and you change the angle of the mirror, the light goes off in a new direction and not back to it's source. Light will not follow the mirrors as they travel.
I have the same problem with the diagram of gravity. If mass bends space, it would do that in 3 dimensions, not 2. Therefore you can't diagram gravity by warping space in a 2 dimensional plane.
DJ TBOne You are completely correct. The models and diagrams that you see involving a 2d representation of gravity is just for the sake of explanation for the masses. It’s very easy to understand and relate to. Essentially what is happening in the 2d model is what’s happening in 3D space.
@@djtbone001a you have to imagine it's a single photon. the experiment only works in the brain, you can't reproduce it. it proves the point, that's all.
This was an excellent lecture. Young people now need more than ever to have more of this kind of presentation in education, from an early age to different degrees of complexity. How to learn and why they should learn, and how infinitely awe-inspiring the Cosmos really is. Come to think of it, Carl Sagan's brilliant old Cosmos tv show should be standard school viewing for all! :)
I had a great GCSE science teacher called Miss Adams, circa 1996. She taught at Beauchamp College, Oadby, Leicester. She was a great teacher and I’m sure she still is.
Professor Cox brings the wonderful complexity of the sciences into the home of the lamen, he explains in a way that can be quantified and understood, and if it inspires you to pick up a book and begin reading and drawing conclusions for yourself, you'll be all the better for it. May our curiosity of all things never diminish.
I started watching this at midnight but couldn't bring myself to stop watching until the very end, I suppose that's when you know you've been successful in communicating how interesting physics and science actually are.
He is so fantastic, you can see he honestly adores science, as do i, he simplifies everything so well , even the hardest things to understand....brilliant!!!!
How can the BBC justify programs like Greatest dancer, The great british sewing bee and other saturday night rubbish and drop programs like Stargazing live? I understood that the BBC was here to entertain and inform,not to treat us like mushrooms.
You and Jim Khalili are such an inspiration. My life would've been so different had I had teachers like you in high school. I hated maths and found physics so obtuse. In a few lectures, you made me fall in love with both.
I finally made it to my first physics lecture yesterday in Minneapolis. Brian Cox is much better in real life to listen to although I still enjoy listening to his older lectures. I'll return to every lecture he has within 200 miles for the rest of my life
Very interesting although i have read this in books and i have watched his shows, a really good DVD is "So you think you know reality" It features Brian, its about quantum physics and includes all the stuff from "What the bleep do we know" and more, its almost 3 hours long, great for quantum beginners and if you have a thirst for understanding you will love it. It seems very hard to come by though.
A brilliant lecture and a wonderful testament from Brian to the importance of scientific research. Long live this kind of research! Allow the accidents of science to enrich our world - Penicillin, MRI, the internet ★
Something I've noticed in all of the Brian Cox lectures I've watched is that he is always smiling. I don't think that he is faking any of his enthusiasm; he really enjoys physics.
Unbelievable! I'm absolutely thrilled by the ease with witch he's talking! Everything seems so simple! I wish I had a chance to talk with Brian Cox someday....
40:00 Watching this video 10 years later and seeing Prof B. Cox calling a prediction of a particle that may not even exist because a mathematical equation and then realize that this particle was the higgs boson and this video is from 2012 and the higgs was discovered on 2015 is just 🤯. When he was giving this lecture the higgs boson wasn’t discovered yet and he said the math predicted it, 3 years later BOOM 💥 the particle is here, science is awesome indeed 🔥🔥🔥
Really great lecture by Brian. In fact all of them are. What I just learned from this one is, if I just keep moving , well I guess relative to you, I'll live longer! Gotta go cause it's not easy typing this when you're jogging :-)
i loved this lecture, i wonder if there is one where he spends more time on the problem of gravity, but i imagine he would have needed another hour at least.
Mr B Cox has had an influence on my life with out me even realising it. He can connect with people in a way that only a very select people are allowed to.
I've lived around Oldham for the last 12 years, and just found out Brian Cox grew up here... I'm gobsmacked as there are no indications anywhere of this, and strongly believe there should be!
The analogies that Brian Cox presents are definitely one of the easiest ones to grasp. I've been interested in astrophysics and astronomy for 8 years now, and there are concepts which are so hard to grasp.. Like the expanding universe. The raisins in the bread analogy just made it really CLICK for me, and suddenly my mind could grasp and visualize what actually happening RIGHT NOW. When he said that I literally laughed until I cried, because something clicked in my head and I knew I finally really understood it for the first time.. I'll go out on a limb and say Brian Cox is an equal caliber of educator and science-presenter as Richard Feynman was.
I've watched this from beginning to end and I don't know alot about what he's saying but I try to ,and sometimes I try to think my brain could be as smart as a physicist like Einstein, and I close my eyes and try to think differently like him but nothing comes out ..still normal..but im very interested in these topics and also other topics alike
This is why we need all of us.... Out of the billions of people ever born it only takes one to understand the complexities of any really complicated part of nature and explain to us other mortals. Flight first finally happened in 1903 - but we were on the moon in 1969. Someone somewhere over the next few decades will tell the rest of us about those missing pieces of the jigsaw so we can go to the stars; I hope I'm still around to see it.
Oh many great things happened within a hundred meters or a little more of that building. The word's first stored program computer, John Dalton giving birth to atomic theory, Emmeline Pankhurst starting the push for women's rights and the vote.... many many things. We're extremely proud of this little city of Manchester. :)
So as light travels through space it's wave gets stretched thus altering it's frequency. I don't get why it is stretched. What makes it stretch? Why doesn't it carry on at the same rate? Please someone explain this is bugging me.
You wrote your comment 6 years ago, i dont know if you ever Got your question answered. The Reason for why the light waves are being stretched, is simple because the Universe is still expanding. So when the Universe is expanding, so Will the light that travelled from a far galaxy to reach us. Take for example a balloon, draw a line on it, then fill it with air, youll now see that the Line has expanded in lenght and how wide it is. That is the same thing that happens with the universe. NOT sure youll ever read this comment, bug if you do, and you understand it..then great:-D
Hello Professor, The parsec is a unit of length used to measure the large distances to astronomical objects outside the Solar System. One parsec is approximately equal to 31 trillion kilometres (19 trillion miles), or 210,000 astronomical units, and equates to about 3.3 light-years. en.wikipedia.org/wiki/Parsec also 100,000 million is 100 Billion (US not UK)
Is the universe expansion accelerating because objects are actually moving faster and faster or because the amount of space expanding between the observed object and ourselves is causing it to appear as though things are accelerating?
regarding the age of the universe, it seems ive heard that the hubble constant is increasing, in other words that the rate of inflation is getting larger. This implies that it hasn't always been "42" or the equivalent worked out, and that the age of the universe might not be 13.7 billion years at all, since the inflation rate might have been slower in the past
Brian is great inspiration to this young audience. Such a wonderful presenter. I wonder what that last question was - I assume something about conflict between religion and science. Never a comfortable question for true scientists to discuss. One is faith in the unerring and unquestionable accuracy of mythology. One is the non faith based search for evidence proving theory. For me, the latter is of consequence.
All I want to know is (simple question I know), what the hell drives "nature" and will we ever work it out? This is well out of my own realm of understanding. But people like Brian and others at the cutting edge leave me in awe. Maybe, hopefully, in my lifetime...
It's only going to get worse. This is the beginning of the end. Read this stuff in the Bible years ago and couldn't imagine how any of it could possibly happen and now I'm living it...all of it and much more to come.
grant houghton we don’t really know yet science seeks to find this out Honestly I see a lot of people call science and scientists arrogant but no science is objective it does not boast stuff it only finds out things
At first I was just searching physicist mentioned in The Big Bang Theory sitcom, end up in here and watching the whole videos. And now searching for more.
In a 2.5 minute long snippet starting at 1:12:50 Brian says exactly what I thought, but I couldn’t say it this well: “I personally don’t see an enormous conflict between science and religion. I think that anyone who says there is a conflict is misunderstanding both.” Amen to that! 😂
