Quantum field theory was originally developed for the treatment of electrodynamics, immediately after the completion of quantum mechanics and the discovery of the Dirac equation.
Most of physics is about energy, and physicists understand inefficiencies. I wanted to write a book about our energy options in a neutral, human-accessible form.
If I have succeeded better than many who surround me, it has been chiefly - may I say almost solely - from universal assiduity.
What we need is a full field guide to the microbes that live in and on people, so that we can understand what they're doing to our lives. We are them; they are us.
In no other type of warfare does the advantage lie so heavily with the aggressor." James Franck, The Manhattan Project neatly summarize the atmic bomb.
Jail threats did not dissuade Martin Luther King - and intergenerational justice is a moral issue of comparable magnitude to civil rights.
What is frustrating people, me included, is that democratic action affects elections but what we get then from political leaders is greenwash.
We found evolution will punish you if you're selfish and mean. For a short time and against a specific set of opponents, some selfish organisms may come out ahead. But selfishness isn't evolutionarily sustainable.
I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.
The question was, 'Is there a way of minimizing the amount of damage you're doing so that you can then study cells in a physiological manner while also studying them at high spatial and temporal resolution for a long time?'
Over the years, a number of other intriguing experimental ideas and areas of investigation have been the objects of my attention, and I have devoted some time and effort to exploring the inherent possbilities.
I soon became convinced... that all the theorizing would be empty brain exercise and therefore a waste of time unless one first ascertained what the population of the universe really consists of.
For some years I have spent my time on exactly these questions - both in thinking about ways to prevent war, and in thinking about how to fight, survive, and terminate a war, should it occur.
If you are a responsible scientist, you are going to present your new results in a paper, and maybe if, over time, things are established, and it's prime time for the public to hear about it, then you include it in a book.
Every time a bit of information is erased, we know it doesn't disappear. It goes out into the environment. It may be horribly scrambled and confused, but it never really gets lost. It's just converted into a different form.
When you think you're listening to several conversations at once, they tell me, you may really simply be time sharing - that is, listening a little bit to this one, a little bit to that one.
It is one thing for the human mind to extract from the phenomena of nature the laws which it has itself put into them; it may be a far harder thing to extract laws over which it has no control.
Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.
It would appear that the number of nonsense triplets is rather low, since we only occasionally come across them. However this conclusion is less secure than our other deductions about the general nature of the genetic code.
There's something really beautiful about science, that human beings can ask these questions and can answer them. You can make models of nature and understand how it works.
In the Pythagorean system, thinking about numbers, or doing mathematics, was an inherently masculine task. Mathematics was associated with the gods, and with transcendence from the material world; women, by their nature, were supposedly rooted in thi...
