    Skill vs. Luck: Analyzing Probability in Stock Picking and Portfolio Management

    Hi, I am reading the book "Fooled By Randomness" by Nassim Nicholas Taleb and ran into what I think is a statistics/probability question. In the book Taleb is talking about how even if the process of picking stocks was completely based on luck (ie. in a given year there is a 50% probability of...

    Why Does a DC Generator Crank Easily with No Load or Disconnected Wires?

    I think I'm still a little confused. If the rotating magnets in the generator move electrons through the wires as they pass by it gets harder to move the electrons and hence turn the magnets and turn the crank if a resistor or load is connected into the circuit. But why in a broken circuit does...

    Why Does a DC Generator Crank Easily with No Load or Disconnected Wires?

    Hi, this question might seem really basic but I can't seem to wrap my head around it. For a DC generator (like the hand cranked ones used in science experiments) the generator gets harder to crank when connected to a resistor since it is harder to move the electrons through the wire/circuit. The...
