It also seems that he works at least partially on his own stuff. For me personally, there is a big difference between working on something for someone, and working on my own ideas. The latter tires me much less.
It is very likely to be a combination of innate predisposition and behavioral effects. Like almost all diseases that are not caused by external bodies, or extremely hereditary. So ADHD is not really a condition, rather, it is an axis on which you can fit somewhere. In extreme cases, I can imagine it's very hard to manage without pills. In most cases, one can probably work through it without pills.
This is still an area of active research [1,2]. The basic hexagonal symmetry comes from the hexagonal lattice of bulk ice. What is more intriguing is the global symmetry between individual dendrites. From reading some recent papers, I think the mechanism is as follows. The snowflake is small enough that although the temperature and water pressure surrounding it can change quickly, all its dendrites are always exposed to almost identical conditions at a given time, leading to a largely deterministic growth, hence the symmetry.
First, the symmetry is not perfect with most snow flakes, if you look closely. Second, I guess there are asymmetric flakes, but they are probably rare. I’m sure though that no current model can explain the distribution of the degree of symmetry, perhaps not even an order-of-magnitude guess.
From the link: "On device revoke, the revoking device makes a new master key, encrypts for the private key for all remaining devices, and writes the new master key to the sigchain along with the statement revoking the old device."
Exactly. Sorry for the doc bug there. s/master key/PUK/g, now fixed on the site. An earlier internal name for PUKs was "master keys" but we've since changed.
Wouldn't it be more conclusive to look at what neuronal signals travel from the lower back to the brain, and how (if) they differ between chronic-pain patients and healthy people? Or do we miss technology to do that?
Yes, but then the whole ecosystem is missing micropayments. I subscribe to some sources, but sometimes I just want to read a single article. Would gladly pay 20 cents, if it was a matter of a click.
Yes, but Paypal nor Walmart don’t handle irreversible transactions. Nor are they platforms on which apps and custom transactions can be implemented. So I don’t think this is a good analogy.
