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.

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.

Such a fantastic speaker. He brings an implausibly complex subject to the masses through the art of storytelling. Superb.

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.

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.

I love how exactly when the man at the beginning says, "No flash photography," a flash goes off.

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.

Brian Cox is the Sagan of our time.  Such an eloquent and well-spoken man who helps others understand the Universe in a fun and lay way.

You certainly can tell that Brian admired Carl Sagen. His excitment is infectious much like Mr Sagan's was..

Big thumbs up for Brian Cox. He's engaging, super bright and charismatic. I hope his enthusiasm for science rubs off on lots of young people.

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.

"Those who think there is a conflict of religion and science, have a poor understanding of both" ...that was amazing!

Brian Cox is the most elegant gentleman in physic community I have ever seen.

Brian is always so happy and enthusiastic <3

Can't get enough of this guy, totally absorbing. Thanks for posting.

Sir Patrick Moore is the old school person

Lecture starts at 8:45

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.

"No flash photography..." *FLASH*

I seriously just love this guy. What an amazing communicator. His enthusiasm is contagious. I love how he always talks with a smile!
