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.

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.

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.

I cannot stress often enough that what science is all about is not proving things to be true but proving them to be false.

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.

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.

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.

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.

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.

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.
PeopleToolsNonsenseQuestioning
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 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.
