In World War II, a British mathematician named Alan Turing led the effort to crack the Nazis' communication code. He mastered the complex German enciphering machine, helping to save the world, and his work laid the basis for modern computer science. Does it matter that Turing was gay?

I do my workouts in the morning, and often I'll take someone from my team. The person I'm meeting with can pick the class, whether it's a spin or barre class, or going for a power walk. It's hard to run and talk - I haven't mastered that yet.

I like their slogan 'making uncommon knowledge common' very much, but as far as I can tell Elsevier has not mastered this job well. Sci-Hub is helping them to fulfill their mission.

Every job is different. I don't think that I've ever had that wonderful feeling when you've finished a job or where you feel like you've mastered it or sort of nailed it... You can never be satisfied. If you're satisfied, it's time to retire.

When I started out, I wrote the songs, recorded the songs, mastered, mixed, did the artwork, made the packaging and did the distribution, all myself. Now I understand what everyone's jobs are, who is doing them right, and who isn't.

After 'Entourage,' it completely opened up my casting within the industry. People saw me for a lot of roles that I hadn't been seen for before. Older roles. I went out this pilot season for a lot of lawyers and doctors. And cops - which I haven't quite mastered yet; I find that quite difficult.

Growing up with a famous father, and one who mastered his craft, it's one of those things where, do you really want to be in the same profession? I can't imagine the pressure on, say, Michael Jordan's kids. But for me, I think it's molded me into the character that I am today.

You aren't going to show me something I haven't seen. Nobody can bring something to me that I don't already know, not in boxing. That's where I've mastered my trade, I can't talk in other fields.
