Astronauts have been stuck in low-Earth orbit, boldly going nowhere. American attempts to kick-start a new phase of lunar exploration have stalled amid the realisation that NASA's budget is too small for the job.
For my Oxford degree, I had to translate French and German philosophy (as it turned out, Descartes and Kant) at sight without a dictionary. That meant Germany for my first summer vacation, to learn the thorny language on my own.
For me, an area of moral clarity is: you're in front of someone who's suffering and you have the tools at your disposal to alleviate that suffering or even eradicate it, and you act.
I think we will see better vaccines within the next 15 years, but I'm not a scientist and am focused on the short-term - what will happen in the interim.
The only way to do the human rights thing is to do the right thing medically.
One of the things we have to acknowledge is that if you look at Haiti, many billions of dollars have gone into development aid there that have not been effective.
I recommend the same therapies for all humans with HIV. There is no reason to believe that physiologic responses to therapy will vary across lines of class, culture, race or nationality.
I've been asked a lot for my view on American health care. Well, 'it would be a good idea,' to quote Gandhi.
I remember being fascinated by ants and wasps and other bugs when I was a kid. I'd set out a Coke can and stand back 20 feet and use my telescope to watch wasps land on it.
Had we really succeeded therefore in altering the period of vibration, which Maxwell, as I have just noted, held to be impossible? Or was there some disturbing circumstances from one or more factors which distorted the result?
According to well-known electrodynamic laws, an electron moving in a magnetic field is acted upon by a force which runs perpendicular to the direction of motion of the electron and to the direction of the magnetic field, and whose magnitude is easily...
The adequate study of culture, our own and those on the opposite side of the globe, can press on to fulfillment only as we learn today from the humanities as well as from the scientists.
As president of the American Historical Association, I started a programme to make dissertations into e-books in 1999. Before I knew it, I was involved in other electronic projects. Harvard invited me to become director of the libraries in 2007.
To this day I always insist on working out a problem from the beginning without reading up on it first, a habit that sometimes gets me into trouble but just as often helps me see things my predecessors have missed.
My mother also had us take piano lessons, and this had a similar effect. I hated those lessons, but I now play regularly for pleasure and have even tried my hand at composing.
When I moved to Stanford I began to pursue the line of research I have been following ever since, namely trying to understand the larger implications of fractional quantum hall discovery.
According to the belief, molecules closer together than 200 nanometers could not be told apart with focused light. This is because, in a packed molecular crowd, the molecules shout out their fluorescence simultaneously, causing their signal, their vo...
Archaeologists have used aerial photographs to map archaeological sites since the 1920s, while the use of infrared photography started in the 1960s, and satellite imagery was first used in the 1970s.
Archaeologists gave the military the idea to use aerial photographs for spying and field survey. We are fortunate that the spatial and spectral resolutions of the imagery available to us are so broadly useful for archaeology.
I think archaeologists are stuck, and we are losing our past at a very rapid rate. Tens of thousands of sites will be lost, and we've only unveiled a tiny percent of the past.
The probability of an event is the reason we have to believe that it has taken place, or that it will take place. The measure of the probability of an event is the ratio of the number of cases favourable to that event, to the total number of cases fa...
