Where Did Time Come From, and Why Does It Seem to Flow?

‘Nautilus: Is the flow of time real or an illusion?

Physicist Paul Davies: The flow of time is an illusion, and I don’t know very many scientists and philosophers who would disagree with that, to be perfectly honest. The reason that it is an illusion is when you stop to think, what does it even mean that time is flowing? When we say something flows like a river, what you mean is an element of the river at one moment is in a different place of an earlier moment. In other words, it moves with respect to time. But time can’t move with respect to time—time is time. A lot of people make the mistake of thinking that the claim that time does not flow means that there is no time, that time does not exist. That’s nonsense. Time of course exists. We measure it with clocks. Clocks don’t measure the flow of time, they measure intervals of time. Of course there are intervals of time between different events; that’s what clocks measure…’

The End of the American Experiment

Umair Haque:

‘It’s Over. So What Can the World Learn?

It’s safe to say, I think, that the American experiment is at an end. No, America might not be finished as in civil war and secession. But it is clearly at an end in three ways.

First, to the world, as a serious democracy. Second, to itself, as a nation with dignity and self-respect. Third, its potential lies in ruins. Even if authoritarianism is toppled tomorrow, the problems of falling life expectancy, an imploding middle class, skyrocketing inequality, and so on, won’t be.

Now, like many fallen nations, maybe America won’t learn much from the failure of its own experiment — but history and the world surely can. So what has the experiment disproven? What was the null hypothesis?

We don’t have to look very far. What does America not have that the rest of the rich world does? Public healthcare, transport, education, and so on. Every single rich nation in the world has sophisticated, broad, and expansive public goods, that improve by the year. Today, even many medium income and even poor nations are building public healthcare, transport, etc. America is the only one that never developed any.

Public goods protect societies in deep, profound, invisible ways …’
