One thing that I've been doing for a long time is to wake up really early. I try to get up around 4 or 5 in the morning, long before most of my lab members are up, which gives me some quiet time to really think without distraction. I think that's important.

Maybe we'll understand more about how the universe came to be, and what forces drove it in the early days and which forces drive it now.

If our brain is understanding some parts of the universe and not understanding other parts, and those understandings are about the laws of physics that our brains are built on top of, then it's kind of a loop, right?

You can imagine over very long timescales, perhaps far beyond the multi-decade time scale, we might be able to ask very deep questions about why we feel the way we feel about things, or why we think of ourselves in certain ways - questions that have been in the realm of psychology and philosophy but have been very difficult to get a firm mechanistic laws-of-physics grasp on.

Many of the projects that we do that appear quite successful, it's actually often the second or third time we've given it a try.

The brain is really hard to see. The whole thing is very large - the human brain is several pounds in weight - but the connections between brain cells, known as synapses, are really tiny. They're nanoscale in dimension. So if you want to see how the cells of the brain are connected in networks, you have to see those connections, those synapses.

We don't have a "consciousness meter" that'll tell us exactly how conscious something is. I think we might get there eventually.
