    I can say for sure that Bart will ride over it but I don’t know what is the reason behind this. If I take a guess then it would be as follows,” The force which will pull Bart has something to do with mass and I think at some place the famous formula E=mc^2 will come into picture”.

    There will be no explosion. The reason is that the dynamite also rides on the pole. Hence, it’s clocks are same as the pole’s. Therefore, the machinery which sees that whether the pole has fit inside the barn or not, will notice that both the ends of the pole were not inside the barn simultaneously.

    I think it’s good for me that the spacetime diagrams are introduced later. However, I am not able to conceive the time dilation and Lorentz contraction from demonstration 9. How to get that?
    And also in demonstration 10 both graph don’t look exactly symmetric. In first graph, the axes are coming closer to each other while in second, the axes are going away from each other if we look at the arrows of the axes.

    No. George will see a much steeper slope than me because according to him the horizontal expanse of the mountain has decreased due to Lorentz contraction but there is no change in its height.
