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.

Each day as I travel through downtown Tucson I am amazed at how quickly the most ancient of human behaviors have changed. For as long as there have been Homo sapiens - roughly 200 000 years - people have filled their lives principally with two activities: talking directly with other people and doing physical things.

The pressure on young chefs today is far greater than ever before in terms of social skills marketing skills cooking skills personality and more importantly delivering on the plate. So you need to be strong. Physically fit. So my chefs get weighed every time they come into the kitchen.

In 1948 I entered the Massachusetts Institute of Technology undecided between studies of chemistry and physics but my first year convinced me that physics was more interesting to me.

The technology that threatens to kill off books as we know them - the 'physical book ' a new phrase in our language - is also making the physical book capable of being more beautiful than books have been since the middle ages.

My intention was to enroll at McGill University but an unexpected series of events led me to study physics at the Massachusetts Institute of Technology.

The laws of physics should allow us to arrange things molecule by molecule and even atom by atom and at some point it was inevitable that we would develop a technology that would let us do this.

These days the technology can solve our problems and then some. Solutions may not only erase physical or mental deficits but leave patients better off than "able-bodied" folks. The person who has a disability today may have a superability tomorrow.

Piecemeal social engineering resembles physical engineering in regarding the ends as beyond the province of technology.

My mother a teacher encouraged me to use my creativity as an actual way to make a living and my father a Mississippi physician did two things. First he taught me that all human beings should be treated equally because no one is better than anyone else and he never pressured me to become a doctor.

I love films that make me react emotionally and physically when you walk out of the cinema. Two of my favorite films however have got to be 'The Tree Of Life' and 'The Piano Teacher ' which also stars one of my favourite actresses Isabelle Huppert.

I'm the son of an everyman. My father is a teacher. He teaches physics at a boys' school in Sydney.

My physics teacher Thomas Miner was particularly gifted. To this day I remember how he introduced the subject of physics. He told us we were going to learn how to deal with very simple questions such as how a body falls due to the acceleration of gravity.

I get hired by companies to hack into their systems and break into their physical facilities to find security holes. Our success rate is 100% we've always found a hole.

The first requisite for success is the ability to apply your physical and mental energies to one problem incessantly without growing weary.

My success and my misfortunes the bright and the dark days I have gone through everything has proved to me that in this world either physical or moral good comes out of evil just as well as evil comes out of good.

About 10 000 years ago males and females were acting equitably and were treating one another as equals and then males took over the power because they have physical power and physical strength.

I was captain and should have set the example. I would lift a minimum of weights. Mine was natural physical strength. I always thought quickness and agility were much more important.

And partly the worst thing you could do in my family was need something from someone. So physical strength represented an avenue of self-sufficiency to me.

The glimpses of human strength and frailty that a physician sees are with me still.

I had no doubts I could go to the pole. I may not be as strong but I make up for physical strength in other areas like steadiness and not panicking under stress.

Physical strength in a woman - that's what I am.

I was a weedy kid not like one of those working-class men who can accommodate not being academically clever by physical strength and prowess.

I'm not sure I have the physical strength to undertake a novel.
