Scientist Quotes

One of the reasons NEOWISE is so valuable is that it sees the sky in the thermal infrared. That means that instead of seeing the sunlight that asteroids reflect, NEOWISE sees the heat that they emit. This is a vital capability, since some asteroids are as dark as coal and can be difficult or impossible to spot with other telescopes.
Our solar system is actually a wild frontier, teeming with different, diverse places: planets and moons, millions of objects of ice and rock.
People have discovered asteroids in the Main Belt that outgas like comets, and things on cometary orbits that no longer outgas - that don't have tails. We're finding all of these unique cases.
The basic method to find asteroids hasn't changed much in hundreds of years. So asteroids in a telescope look just like stars with one exception: They move with time.
The best thing to do is to study these asteroids so we know the range of parameters we would have to deal with and also to find them so we have as much time as possible to prepare.
There are all these interesting rules about asteroid nomenclature. Once you discover it, you have the right to name it, but there's a catch.
There are physical bodies, physical worlds that astronauts could visit, that we haven't found yet. Especially, there's these close approaches of asteroids. They pass within geosynchronous orbit sometimes, and they pass within the Earth and the moon.
There's been a lot of really great intensive research into earthquakes, but we can't predict an earthquake down to the day. We can't predict where a hurricane is going to be a month in advance.
We have a telescope that takes images, and we use a very nice computer program to isolate the moving images. And then, every potentially new asteroid is vetted by eye, so we take a look at each one, and then we send our observations to the Minor Planet Center.
We've actually named asteroids for other famous women in history, like Rosa Parks, Harriet Tubman, and Sojourner Truth. But it's really this Malala one that's catching people's attention.
When I tell people I'm a space scientist studying asteroids, they sometimes assume I'm a super-smart math whiz. The kind of person who skipped a bunch of grades and went to college when they were sixteen. Although I am good at math, school was difficult for me, and I didn't get straight A's.
As we returned to Argentina, I started seriously to work towards a doctoral degree under the direction of Professor Stoppani, the Professor of Biochemistry at the Medical School.
Back in 1962, when I had by accident become the supervisor of Roberto Celis in Argentina, it occurred to me that antibody diversity might arise from the joining by disulphide bridges of a variety of small polypeptides in combinatorial patterns.
I wasn't a particularly brilliant student, but on the other hand, I was very active in Student Union affairs and in student politics.
My father was a Jewish immigrant who settled in Argentina and was left to his own devices at the age of 15. My mother was a teacher, herself the daughter of a poor immigrant family.
My thesis was on kinetics studies with the enzyme aldehyde dehydrogenase. When that was finished, I was granted a British Council Fellowship to work under the supervision of Malcolm Dixon.
The study of the amino acid sequence around the disulphide bonds of the immunoglobulins was my own short-cut to the understanding of antibody diversity.
What attracted me to immunology was that the whole thing seemed to revolve around a very simple experiment: take two different antibody molecules and compare their primary sequences.
When an animal is infected, either naturally or by experimental injection, with a bacterium, virus, or other foreign body, the animal recognises this as an invader and acts in such a way as to remove or destroy it.
I have steadily endeavoured to keep my mind free so as to give up any hypothesis, however much beloved (and I cannot resist forming one on every subject), as soon as facts are shown to be opposed to it.
