There is a famous Iraqi idiom which states that if you think your opponents can eat you for dinner, then you'd better eat them for lunch. If your opponent is too big and powerful to eat you right-now, you'd better eat them for lunch before they eat you. Commitment problems from our opponents lead us to act, and that's another reason why rational man can go to war.
— Christopher BlattmanWater is the essence of life. On Earth it's used to grow plants and within industrial processes but in space it takes on a whole new form. We can use water as a radiation shield. One cubic metre of water gives the same protection as Earth's atmosphere and magnetosphere. Water is a molecule made of hydrogen and oxygen- and that happens to be rocket fuel.
It's a combination of passion, vision, creativity and a sense of adventure.
Despite huge and on-going technological advances in electronic transactions technologies, it has remained surprisingly durable, even if its major uses seem to be buried in the world underground and illegal economy.
This principle demands careful consideration of protection that must be given to civilians and civilian property, balancing military objectives against foreseeable collateral damage. This balance cannot be made by a formulaic algorithm – there isn't one – but by human judgment. In recent decades, it has become apparent that that human judgement is assisted by legal advisors who play a crucial role in these decisions, offering guidance on the legality of military actions.
On a fundamental level, any experience that nudges your mind to engage from a unique angle is immensely valuable. Art, for instance, demands a different set of appreciation and communication skills. It invites you to respect and marvel at someone whose talents may be starkly distinct from your own.

It was a nice day, but I wasn't going anyplace.
The perspective of seeing the Earth from space has rewired our brain. We used to have a 2-dimensional view for hundreds of thousands of years. Now with space telescopes we have a 4-dimensional view of our universe.
There are two key features of blockchain that make it, potentially, a very useful technology from an economic perspective. First, the data about transactions are posted on many public sites thus giving these data an immutability that makes disputes easy to avoid. Second, although the data are in some sense public, they can be encrypted so that a particular party learns only those aspects that she needs to know.
If you want to have a great startup idea, don't try to think of a startup. If you focus on creating a startup, you'll be grounding yourself in the present, studying customers living in the present, their problems in the present, and their unmet needs in the present.
The head of the Bank of England, Mervyn King, privately criticised David Cameron and George Osborne before the election for their lack of experience, the lack of depth in their inner circle and their tendency to think about issues only in terms of their electoral impact.
When I was a journalist, you had to always have three sources, or they would not run the story. Now, according to 'sources', not even on-the-record, is good enough. Everyone wants to be first and often that leads to mistakes.
No one man can, for any considerable time, wear one face to himself, and another to the multitude, without finally getting bewildered as to which is the true one.
