Lisa Randall
Lisa Randallis an American theoretical physicist and an expert on particle physics and cosmology. She is the Frank B. Baird, Jr. Professor of Science on the physics faculty of Harvard University. Her research includes elementary particles and fundamental forces and she has developed and studied a wide variety of models, the most recent involving extra dimensions of space. She has advanced the understanding and testing of the Standard Model, supersymmetry, possible solutions to the hierarchy problem concerning the relative weakness...

You have to be careful when you use beauty as a guide. There are many theories people didn't think were beautiful at the time but did find beautiful later—and vice versa. I think simplicity is a good guide: The more economical a theory, the better.
Physics has entered a remarkable era. Ideas that were once the realm of science fiction are now entering our theoretical — and maybe even experimental — grasp. Brand-new theoretical discoveries about extra dimensions have irreversibly changed how particle physicists, astrophysicists, and cosmologists now think about the world. The sheer number and pace of discoveries tells us that we've most likely only scratched the surface of the wondrous possibilities that lie in store. Ideas have taken on a life of their own.
I think it's a problem that people are considered immoral if they're not religious. That's just not true.... If you do something for a religious reason, you do it because you'll be rewarded in an afterlife or in this world. That's not quite as good as something you do for purely generous reasons.
It's hubris to think that the way we see things is everything there is.
When people try to use religion to address the natural world, science pushes back on it, and religion has to accommodate the results. Beliefs can be permanent, but beliefs can also be flexible. Personally, if I find out my belief is wrong, I change my mind. I think that's a good way to live.
I did not set out to explain the extinction of the dinosaurs. I'm a particle physicist, and I was actually thinking about dark matter along with some collaborators.
The scientist is also a composer... You could think of science as discovering one particular thing - a supernova or whatever. You could also think of it as discovering this whole new way of seeing the world.
The standard model of particle physics describes forces and particles very well, but when you throw gravity into the equation, it all falls apart. You have to fudge the figures to make it work.
The stuff we're really famous for was really lucky in a way.
I started out working on supersymmetry. The theory predicts that for every particle we know about, there will be an additional particle.
The thing I will say is that probably culturally, women are treated differently, which means, I think, you're criticized more, you have to listen a little bit more, you have to justify yourself.
Scientific experiments are expensive, and people are entitled to know about them if they want to. I think it is very difficult to convey ideas.

We live in a world where there are many risks, and it's high time we start taking seriously which ones we should be worried about.
