A common topic of conversation is what people would do if they won the lottery. People often dream of winning it big any buying big houses, nice cars, and quitting their jobs.

One of the more interesting and important parts of studying two different sets of data is to see if they are correlated. It might make one wonder if the order of the data matters. In this blog post, I show with three different methods - by an empirical example, by looking at the correlation function, and visually - why the order doesn’t matter so long as each data point is matched to the same datapoint each time.
One of the most challenging aspects of investing is lack of foreknowledge or future knowledge - we simply do not know what the performance of a stock or index fund will be. But what if we could print out a list of opening values of a stock and then take a time machine backward in time and invest with foreknowledge? Would we be able to make much more money than otherwise possible?
For a while, my Facebook Android App had a little rocket ship along the top menu icons. It turned out this little rocket ship lead to something called the Explore Feed, which was a cool little section on that allowed you to view posts from pages you might like but haven’t necessarily “liked” the page itself. The rocket ship icon shifted position several times, so I figured Facebook was just trying to figure out the optimal placement for it. I really liked the explore feed but after a month or so of the icon moving around, it disappeared completely. I thought Facebook had simply given up on their little project.
