Henry VIII
I have always wanted to write something about London since I came back in early September. But there were so many things to say: the history, the art, the architectures, the religions, the science, and Shakespeare’s Globe Theater, Sherlock Holmes’ imaginary residence on 221b baker street, and Samuel Johnson’s House. So naturally, I don’t know…

New Year Greeting Letter – nerd version
It occurs to me today that if time travel is possible, not only will the chain of causes and effects be disrupted, but also the law of mass conservation will be broken. Science fictions seem to like exploring the consequences of the former, a few of which I happened to watch this week, such as…

With its Grasshopper plugging, which is officially called Explicit History, it can even handle vector operations like…
