Lebesgue Integration is usually introduced in either one of the two ways , in most of the books. Either using measure theory OR skipping measure theory altogether and using approximating functions like step functions, monotone functions etc. The second approach is usually taken so that one can actually understand all the concepts of Lebesgue integral with out going through measure theory. However that approach would make it difficult for a reader to connect Lebesgue Integral and concepts relating to stochastic processes.

How superb to become wise with out being boring; how sad to be boring with out being wise - Taleb

Via efinancialnews.com But in recent weeks trading geeks have started to talk about picoseconds in what is a truly mind-boggling concept: a picosecond is one trillionth of a second. Put another way, a picosecond is to one second what one second is to 31,700 years. Why on Earth (which spins at a rate of 460 meters a second) is it necessary to trade so fast? The answer is simple. Firms that trade super fast effectively put themselves at the front of the trading queue and have priority over other orders.

“Always produce” is a heuristic for finding the work you love. If you subject yourself to that constraint, it will automatically push you away from things you think you’re supposed to work on, towards things you actually like. “Always produce” will discover your life’s work the way water, with the aid of gravity, finds the hole in your roof. - Paul Graham
