that is, the expansion of universe is not only expanding, which we know for a long time, the expansion is not slowing down as you would think because gravity pulling things together, but it's speeding up. and this we think can only be because of this dark energy. >> steven weinberg you won the nobel prize in physics in 1979 for what? >> a theory that unified two of the basic forces of nature. we know in broad terms of four basic forces as elektra magnetism is reasonably familiar to people, gravitation. we've known about that for a long time. and then to forces that only act inside the nucleus of the atom. the strong nuclear force that holds the particles together, and the weak nuclear force that causes them to change their nature. the theory that was honored, and i share the prize with two other people, was a theory that unified two of these forces. the electromagnetic force and the weakening force. and the prize would not have been awarded at all except that made some new predictions which were then verified by experiment. >> you say you do most of your work from your home on lake aus

the university's footprint with a new campus in neighboring allston. it included a billion-dollar state-of-the-art science center. the university was able to afford the expansionnks to a rising endowment. summers was seen as a change agent and quickly made his presence felt across campus. but his opinionated and brash style, eventually landed him in hot water. in 2005, summers created a furor when he gave a speech and raised the issue of women's aptitude for the hard sciences. soon after, harvard's faculty of arts and sciences passed a vote of no confidence in him. within a year, summers was gone and harvard was searching for a new president. in february, 2007, the news was out: drew faust had been chosen. >> everyone recognizes the name harvard. to have a woman leading this extraordinary, complex multimillion dollar institution recognized throughout the globe is a major statement about the advancement of women in leadership. >> susie: sheila wellington is an expert on women's leadership and has written many books on women in business. >> drew faust had leadership, she had smarts, but she also has dignity and operational capacity. that's an unusual combination

of us who are university educators. today dr. sanders will give us the benefit of his expertise and skills to analyze eisenhower's racial views and the little rock crisis. so without further expansion on my part, i will turn the microphone over to mr. marshall. >> thank you, doctor. i want to thank the library and the foundation for putting together this series of programs and for allowing me to come out and participate. it's been a wonderful excuse for me to build on what i have read and studied about president eisenhower's service to our country. and i've enjoyed it immensely. as some of you know, we had hoped that former secretary william coleman could join us for this discussion. but his inability to join us today gives me a chance to quote from his book which i promise you he would have done liberally this afternoon. but as a true pioneer in his own right, secretary coleman's observations, i find highly persuasive in terms of president eisenhower's contributions and the way in which he went to bat his job. as many of you know, the 1952 campaign did not really touch very much if at all on civil rights issues. but for those who knew president eisenhower it could not have been to

universal coverage is romn romneycare. the problem with the president's plan is although we talk about it as if it were romney care, the real energy of it comes from this huge expansionvery troubled program. half the people who will gain coverage under the president's plan gain not through mandates and private insurance but through medicate. on energy, yes, at one point there was talk of a very complicated form of tradable permits. democrats themselves in congress abandoned that as you know because of objection from state democrats and what the president has fallen back on is his plan b which is direct government investment to pick winners in solar energy and windmill subsidies. exactly the approach that has not worked since it was tried in the 1970s, again and again. consistently failed. >> let me give will cain the final question to you and then run to a break. >> i want to remind people, david's piece is a response to andrew sullivan's, critics of president obama is stupid. >> dumb is the word they used, dumb. >> when you make the argument, plenty of evidence to suggest he is infusing the government into our markets and our lives from energy policy, david points t
