How we explore unanswered questions in physics | James Beacham

James Beacham looks for answers to the most important open questions of physics using the biggest science experiment ever mounted, CERN's Large Hadron Collider. In this fun and accessible talk about how science happens, Beacham takes us on a journey through extra-spatial dimensions in search of undiscovered fundamental particles (and an explanation for the mysteries of gravity) and details the drive to keep exploring.

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less). Look for talks on Technology, Entertainment and Design -- plus science, business, global issues, the arts and much more.

Thumbs up for TED this is what I want to see

"We live in a 3-dimensional universe... I hope that's a non-controversial statement?"

This guy has a great sense of humour and he explains everything so well. You've gotta get him to do another talk..

[kengoodey]

I am not a scientist and I find this guy very easy to watch and listen to. I'm not saying that I now understand, but he's the kind of communicator who will help me to get there (if I ever do!).

[donciterenyi]

This was a TED talk worth watching! Thanks

[HeyHax]

Finally an actual interesting lecture.

"Imagine two cars colliding, they disappear on collision and in it's place is a bicycle which then explodes into skateboards"
Quantum physics

One of the best TED talks I've seen. great work!

In this moving talk, Particle Physics Scholar James Beacham explains the story behind the misunderstanding of Higgs Boson Particle reportedly deducted by his lab : CERN Large Hardron Collider. Succinctly he highlights the importance of curiosity in science experiments. It is not always finding something that fascinates, but it's trying new ideas and novel approaches that makes the difference. Well said. Highly recommended talk.

What an amazing talk! It got anticlimactic for a second, but he wrapped it up so well.

[florbz]

I can so imagine physics going in a completely new direction and starting a new beginning! A whole revolution in particle physics after we think everything we need to know has been discovered but it turns out we were either wrong or simply only skimmed the surface! Hopefully this happens before I die!

[JacMarinoChen]

God Bless this man. What a gem of a human.

[tbpom]

thumbs up for scientists!! I love his comparison between space exploration and science experiments lol

[passivesn]

Perhaps Gravity is distributed equally proportionally between the dimensions holding the dimensions in a stable spacial form providing the foundation for the Higgs field to create the quantum and coalesce into the subatomic particles that make up atoms?
If that is the case and we are able to determine the number of dimensions, we could calculate the gravitational force of the universe. A grand approach to explaining dark matter and dark energy that holds galaxies and perhaps even the universe together.

Come on, stop judging his appearance! Some would kill to have his looks. He's totally OK, if not more. It's not a fashion show, it's an intellectual lecture. And an enlightening one at that. He speaks well, which is the most important.

Thanks TED for a more scientific talk, unlike these later Stories of Encouragement and Inspiration. The latter is not bad, but I prefer to see hard science.

[lucyjeong]

Cool. I would have considered studying physics if I could have watched this in my teens

[grahampalmer]

The problem is in imagining two separate systems. It's only one. Oh, and gravity isn't leaking out. It's leaking in.

[Helliving]

Finally something I can learn from and not someone complaining about life! Ty for this Ted Talk... I've missed this :)

[Djolewatchtastife]

I swear these talks are incredibly inspiring. I hope to one day help physicists to advance the discovery of these new particles with the help of computer sciences.

看到最后他说particle physicist就是探索者那段差点把我感动哭了！

[heitormb]

u guys should put more talks about science... thats really interesting to us, and we get more information about it and we become smarter.
