For many, to live in a universe that may have no purpose, and no creator, is unthinkable.
Empirical explorations ultimately change our understanding of which questions are important and fruitful and which are not.
One might rationally argue that individual human beings should be free choose what moral behavior they approve of, and which they don't, subject to the constraints of the law.
By no definition of any modern scientist is intelligent design science, and it's a waste of our students' time to subject them to it.
If innovations were predictable, they wouldn't be discoveries.
No one intuitively understands quantum mechanics because all of our experience involves a world of classical phenomena where, for example, a baseball thrown from pitcher to catcher seems to take just one path, the one described by Newton's laws of motion. Yet at a microscopic level, the universe behaves quite differently.
I don't know if science and reason will ultimately help guide humanity to a better and more peaceful future, but I am certain that this belief is part of what keeps the 'Star Trek' fandom going.
Feynman once said, 'Science is imagination in a straitjacket.' It is ironic that in the case of quantum mechanics, the people without the straitjackets are generally the nuts.
The biggest conceptual change over the last 100 years in the way physicists think about the world is symmetry.
The root cause of the looming energy problem - and the key to easing environmental, economic and religious tensions while improving public health - is to address the unending, and unequal, growth of the human population. And the one proven way to reduce fertility rates is to empower young women by educating them.
When it comes to the real operational issues that govern our understanding of physical reality, ontological definitions of classical philosophers are, in my opinion, sterile.
Keeping religion immune from criticism is both unwarranted and dangerous.
Religious leaders need to be held accountable for their ideas.
What we can do is provide the tools, through our educational system, for people to be able to tell sense from nonsense. These tools include the scientific method, skeptical questioning, empirical evidence, verifying sources, etc.
Symmetry does mean something different for physicists than for members of the public. It means that an object or a theory does not change when you make some transformation - either rotating or moving it or doing something to the equations.
Imagining living in a universe without purpose may prepare us to better face reality head on. I cannot see that this is such a bad thing.
Neutrinos alone, among all the known particles, have ethereal properties that are striking and romantic enough both to have inspired a poem by John Updike and to have sent teams of scientists deep underground for 50 years to build huge science-fiction-like contraptions to unravel their mysteries.
I cannot stress often enough that what science is all about is not proving things to be true but proving them to be false.
I used to read a lot of science fiction when I was younger.
Nothing can create something all the time due to the laws of quantum mechanics, and it's - it's fascinatingly interesting.
A significant fraction of evangelical voters appear more likely to ignore the candidates' specific economic and foreign policy platforms in favor of concerns about gay marriage or abortion.
On the question of preserving public lands, Trump replies that our elected officials have spent too long rewarding 'special interests,' by which I assume he doesn't mean petroleum companies and the Bundy family.
The Bible is full of dubious scientific impossibilities, from Jonah living inside a whale, to the sun standing still in the sky for Joshua.
When it comes to the things that people really want in science fiction - like space travel - the simplest things end up causing them not to happen. Humans are 100-pound bags of water, built to live on Earth.
The universe has a much greater imagination than we do, which is why the real story of the universe is far more interesting than any of the fairy tales we have invented to describe it.
Empty space is a boiling, bubbling brew of virtual particles that pop in and out of existence in a time scale so short that you can't even measure them.
Organized religion, wielding power over the community, is antithetical to the process of what modern democracy should define as liberty. The sooner we are without it, the better.
It never ceases to amaze me that every second of every day, more than 6,000 billion neutrinos coming from nuclear reactions inside the sun whiz through my body, almost all of which will travel right through the earth without interruption.
Life has survived for more than three billion years because it is robust, and almost no mutations can easily outwit the defense mechanisms built up through eons of exposure to potential pathogens.
Scientists don't read theology; they don't read philosophy. It doesn't make any difference to what they're doing - for better or worse, it may not be a value judgment, but it's true.
The rise of a ubiquitous Internet, along with 24-hour news channels has, in some sense, had the opposite effect from what many might have hoped such free and open access to information would have had. It has instead provided free and open access, without the traditional media filters, to a barrage of disinformation.
We should provide the meaning of the universe in the meaning of our own lives. So I think science doesn't necessarily have to get in the way of kind of spiritual fulfillment.
I have always felt that, aside from research that violates universal human mores, when it comes to technological applications, that which can be done will be done.
Teaching and writing, to me, is really just seduction; you go to where people are and you find something that they're interested in and you try and use that to convince them that they should be interested in what you have to say.
To me, what philosophy does best is reflect on knowledge that's generated in other areas.
One thing I cannot understand - and people are probably going to be upset about this - is why local school boards have control over educational content.
When a person's religious beliefs cause him to deny the evidence of science, or for whom public policy morphs into a battle with the devil, shouldn't that be a subject for discussion and debate?
Aside from communications satellites, space is devoid of industry.
Symmetries are the playing field on which the physical world works and which determine the rules of the game. The symmetries of nature determine for us things that remain constant, that can't be changed. Those are the guideposts in physics, the quantities like energy and momentum.
If our species is to survive, our future will probably require outposts beyond our own planet.
We should teach kids how to question. Now having said that, of course, to be a productive adult, there are certain skills that are required - reading, writing, and, in the old-fashioned days, we used to say arithmetic. Now we say mathematics.
I was most eager to see how Trump would respond to the climate-change question.
I am in favor of saying, 'Okay, let's get teams of educators and experts in certain disciplines to say, 'What are the basic things that we think are an essential part of an early education for people?'' Put them together and create, as well as possible, a set of goals and tools to learn those things.
I can't prove that God doesn't exist, but I'd much rather live in a universe without one.
The illusion of purpose and design is perhaps the most pervasive illusion about nature that science has to confront on a daily basis.
Whatever the evolutionary basis of religion, the xenophobia it now generates is clearly maladaptive.
Science is only truly consistent with an atheistic worldview with regards to the claimed miracles of the gods of Judaism, Christianity and Islam.
We need to walk into the future, no matter how unnerving, with open eyes if society is to keep pace with technology.
Philosophy used to be a field that had content, but then 'natural philosophy' became physics, and physics has only continued to make inroads. Every time there's a leap in physics, it encroaches on these areas that philosophers have carefully sequestered away to themselves, and so then you have this natural resentment on the part of philosophers.
Education is far less about a set of facts than a way of thinking, than learning how to critically think. And therefore, what I always think should be the basis of education is not answers but questions.
There are areas of philosophy that are important, but I think of them as being subsumed by other fields. In the case of descriptive philosophy, you have literature or logic, which, in my view, is really mathematics.
For the record: Quantum mechanics does not deny the existence of objective reality. Nor does it imply that mere thoughts can change external events. Effects still require causes, so if you want to change the universe, you need to act on it.
To the extent that we even understand string theory, it may imply a massive number of possible different universes with different laws of physics in each universe, and there may be no way of distinguishing between them or saying why the laws of physics are the way they are. And if I can predict anything, then I haven't explained anything.
People are interested in science, but they don't always know they're interested in science, and so I try to find a way to get them interested.
Formal logic is mathematics, and there are philosophers like Wittgenstein that are very mathematical, but what they're really doing is mathematics - it's not talking about things that have affected computer science; it's mathematical logic.
It is, after all, impossible in the modern world to shield everyone from nonsense and stupidity.
Richard Nixon, famously, conducted his foreign policy according to the 'madman theory': he tried to convince enemy leaders that he was irrational and volatile in an attempt to intimidate them. But this was a potentially useful approach to foreign policy only because it was an act.
The notion that anyone in the 21st century could take seriously the notion that the sun orbits the Earth, or that the Earth is the center of the universe, is almost unbelievable.
The Internet is a clear example of how our lives have changed in ways we couldn't have imagined: a distributed information source, which is invisible to everyone, where you can access anything, and it's distributed throughout the whole world. Basically, communication is instantaneous.
For a physicist or a mathematician, the most symmetrical object you could think about would be a sphere, because it looks identical no matter what you do to it, however you rotate it in any given direction.
