The caricature of science is that we hold tight to the theories we have, and shun challenges to them. That's just not true. In fact, we hold our highest rewards for those scientists who can prove others wrong. And by the way, they are famous in their own lifetimes. We don't wait until they're dead.Neil deGrasse Tyson
Big ideas, big ambitious projects need to be embedded within culture at a level deeper than the political winds. It needs to be deeper than the economic fluctuations that could turn people against an expensive project because they're on an unemployment line and can't feed their families.Neil deGrasse Tyson
I'm not the sort of person who gives up on things. The first time we crossed the Atlantic in the balloon, it crashed, and we went on and did the Pacific. First time we crossed the Atlantic in a boat, it sank, and we went on and got the record. So, generally speaking, we will pick ourselves up, brush ourselves down, and carry on.Richard Branson
I liked to write from the time I was about 12 or 13. I loved to read. And since I only spoke to my brother, I would write down my thoughts. And I think I wrote some of the worst poetry west of the Rockies. But by the time I was in my 20s, I found myself writing little essays and more poetry - writing at writing.Maya Angelou
All my mind was centered on my studies, which, especially at the beginning, were difficult. In fact, I was insufficiently prepared to follow the physical science course at the Sorbonne, for, despite all my efforts, I had not succeeded in acquiring in Poland a preparation as complete as that of the French students following the same course.Marie Curie
I love those who can smile in trouble, who can gather strength from distress, and grow brave by reflection. 'Tis the business of little minds to shrink, but they whose heart is firm, and whose conscience approves their conduct, will pursue their principles unto death.Leonardo da Vinci
It's one of the few regrets of my presidency - that the rancor and suspicion between the parties has gotten worse instead of better. There's no doubt a president with the gifts of Lincoln or Roosevelt might have better bridged the divide, and I guarantee I'll keep trying to be better so long as I hold this office.Barack Obama
Never stop fighting until you arrive at your destined place - that is, the unique you. Have an aim in life, continuously acquire knowledge, work hard, and have perseverance to realise the great life.Avul Pakir Jainulabdeen Abdul Kalam
Getting ahead in a difficult profession requires avid faith in yourself. That is why some people with mediocre talent, but with great inner drive, go so much further than people with vastly superior talent.Sophia Loren
What might be taken for a precocious genius is the genius of childhood. When the child grows up, it disappears without a trace. It may happen that this boy will become a real painter some day, or even a great painter. But then he will have to begin everything again, from zero.Pablo Picasso
