A Quote by Barack Obama

Ultimately, the challenges of the 21st century can't be met without collective action. Agreement will almost never be easy, and results won't always come quickly. But I am committed to respecting different points of view, and to forging a consensus instead of dictating our terms... That's how we will advance and uphold our ideals.
Computer science teaches and nurtures the type of thinking that 21st century citizens will need to address 21st century issues. We cannot know with any certainty what those challenges will be, but we can arm our students with the tools needed to address them.
I have begun to feel that there is a tendency in 20th Century science to forget that there will be a 21st Century science, and indeed a 30th Century science, from which vantage points our knowledge of the universe may appear quite different than it does to us. We suffer, perhaps, from temporal provincialism, a form of arrogance that has always irritated posterity.
Leadership is the great challenge of the 21st century in science, politics, education, and industry. But the greatest challenge in leadership is parenting. We need to do more than just get our enterprises ready for the challenges of the twenty-first century. We also need to get our children ready for the challenges of the 21st century.
For we have always understood that when times change, so must we, that fidelity to our founding principles requires new responses to new challenges, that preserving our individual freedoms ultimately requires collective action.
Feeding the world will be one of the greatest challenges of the 21st century. It will be impossible without using scientific advancements and biotechnology.
No one wants adversity. Trials, disappointments, sadness, and heartache come to us from two basically different sources. Those who transgress the laws of God will always have those challenges. The other reason for adversity is to accomplish the Lord's own purposes in our life that we may receive the refinement that comes from testing. It is vitally important for each of us to identify from which of these two sources come our trials and challenges, for the corrective action is very different.
Life isn't always easy and we are never guaranteed that things will always go smoothly…It progresses with an almost constant series of challenges, but these obstacles are just detours that we have to take in order to meet our ultimate goals. No matter what sort of adversity or challenge you might face, you can always believe that, with hope, it can be conquered and, in the end, you will be stronger for it.
In point of fact, no conclusive disproof of a theory can ever be produced; for it is always possible to say that the experimental results are not reliable or that the discrepancies which are asserted to exist between the experimental results and the theory are only apparent and that they will disappear with the advance of our understanding. If you insist on strict proof (or strict disproof) in the empirical sciences, you will never benefit from experience, and never learn from it how wrong you are.
More broadly, Prime Minister Lee [Hsien Loong] and I will work to advance the US-Singapore partnership across the board. We're committed to sustaining the dynamism of our economies with the Trans-Pacific Partnership - the highest-standard trade agreement ever - which will support trade and innovation in both our countries.
The way humanity manages or mismanages its nature-based assets, including pollinators, will in part define our collective future in the 21st century.
Donald Trump made it clear in that very interview that America will stand by our allies. We will uphold up our treaty obligations, including the mutual defense agreement that is NATO.
It is easy to imagine that the Buddha, the awakened one, is something or somewhere other than here or that awakening to reality will happen sometime other than now. But as long as we continue to think in terms of time we will deceive ourselves. The you who is chasing enlightenment will never become enlightened. Instead of striving towards some distant goal that you will never reach, I invite you to stop and ask: How am I avoiding the enlightenment that is already present in each moment? How am I seeing separation where it doesn't exist?
The motto of the Netherlands is translated into English as 'I will uphold.' But I want you to know that, as we go forward, our message together is not just 'I will uphold,' but 'we will uphold.'
The more we come to rely on government, the fewer freedoms we will enjoy. Government will start dictating what we can own, eat and drive, how much of our money they will let us keep, how we run our businesses, how many - if any - guns we can own, and what we may and may not say. Oh, wait! They are already doing that. To preserve freedom we must fight for it.
I was never presented with the details as far as the collective bargaining system is Greece. I am in favor of a normal system without giving the labour minister the right to extend the results to extend the result of the collective bargaining to the whole of the real economy. The government has to make sure that the results will not harm the situation of small and medium enterprises.
I believe that the organisers of this conference have chosen a very timely subject for our discussion - because the 21st century will confront us with an entirely new set of challenges.
