Many people who talk about the discovery method of teaching are really talking about arranging a lesson or an experiment so that students discover what they are supposed to discover. That is not an exploration. The whole tradition of exploration is being lost for entire generations.
Curiosity is the essence of human existence and exploration has been part of humankind for a long time. The exploration of space, like the exploration of life, if you will, is a risk. We've got to be willing to take it.
The forces of genetic mixing are so powerful that everyone in the world has Jewish ancestors, though the amount of DNA from those ancestors in a given individual may be small. In fact, everyone on earth is by now a descendant of Abraham, Moses, and Aaron--if indeed they existed.
Why should I need a prescription to spit into a vial and get my DNA read? Why can't I get my own blood drawn without a doctor's permission? It's my blood.
If I wasn't doing this kind of exploration, I'd like to be doing some other kind of exploration. It might be more risky, or less risky, but, in the business of exploration, risk is part of the territory.
Textbooks describe DNA as a blueprint for a body. It's better seen as a recipe for making a body, because it is irreversible. But today I want to present it as something different again, and even more intriguing. The DNA in you is a coded description of ancient worlds in which your ancestors lived. DNA is the wisdom out of the old days, and I mean very old days indeed.
I'm really hopeful about the future of space exploration and human spaceflight. Civilization as we know it has been defined by exploration. You know, we need to go off and find out what's around the next corner and what's just beyond what we already know. It's part of our being; it's part of our moral fiber to go off and explore.
Of all writings I love only that which is written with blood. Write with blood: and you will discover that blood is spirit.
When I looked at the family tree and at where my ancestors lived, it was places like Rothbury and Tropton! I was going, 'No, that can't be the reason why I feel so at home there.' But could it be in my DNA? It's kind of shocking.
Children of those ancient Aryans, through the grace of the Lord may you have the same pride, may that faith in your ancestors come into your blood, may it become a part and parcel of your lives, may it work towards the salvation of the world!
A lot of people say I'm not Mexican because I don't speak a lot of Spanish or am there a lot, but the United States is where it's at. Mexico's in my blood, in my DNA. It's in my kids' DNA.
I think a part of me thought that I might be interested in academia because I really do love school. I mean that on all levels - I like educational environments; I like being part of that community of learning and exploration. And I like to talk.
We need new medical approaches to preventing and/or curing disease. We need new scientific approaches to generating, storing, and being more efficient with energy. Maybe we need more space exploration. Maybe we need more undersea exploration.
I'm lucky because I have so many clashing cultural, racial things going on: black, Jewish, Irish, Portuguese, Cherokee. I can float and be part of any community I want.
I have often noticed that ancestors never boast of the descendants who boast of ancestors. I would rather start a family than finish one. Blood will tell, but often it tells too much.
We now know that the structure of the DNA in humans and chimpanzees differs by only just over one percent. You could even have a blood transfusion from a chimp, provided you have the same blood group.
