Annie Hall revisited
I rewatched “Annie Hall” periodically. I think it’s 1 of these protean works that holds distinct meaning for you, dependent on in which you are in existence. I first saw it when I was quite young, and I keep in mind thinking of it as a powerfully romantic knowledge.
Last night I saw it but yet again, for the initial time in a range of a long time. What struck me this time was how different it seemed. Yes, the lines are brilliant and witty, the timing of the humor spot-on, the cultural digs pitch-best and devastatingly on target, the romantic scenes by the river breathtakingly wonderful to the point of becoming iconic.
However at its core, a thing seemed fundamentally various — the story of Annie Hall and Alvy Singer wasn’t genuinely a romance. Yes, it had all the type of a romance, but this time I recognized that each of the primary characters are completely self-absorbed. The two have a romantic vision of the other, but each is trapped in their personal narcissistic version of reality. This may not be precisely true of the character of Annie, since we are allowed to see her only by way of Alvy’s eyes. But it is definitely genuine of him.
I had believed, on earlier viewings, that the film was a rumination on how true really like can fail to function out. But now I see it as a referendum on infatuation that problems itself for enjoy — the sort of relationship in which one particular or more partners is unwilling to do the function of climbing out of their skin extended enough to genuinely see the other.
Sigh.
Bernoulli revisited, part 2
I was inspired by Bernoulli’s observation that the increased speed of the air on the top side of an airfoil creates a low pressure zone. The car is then lifted by the higher air pressure beneath the airfoil. My twelve year old brain knew that to make a car fly, I necessary to decrease the air pressure above the wing surface — essentially, to displace air away from the best — thereby making a partial vacuum above the automobile. But there was no rule saying that the displaced air had to end up immediately underneath the automobile.
My crazy scheme was to design and style a flying machine that would develop a partial vacuum on its best surface (which is also what a helicopter does), by displacing the air sideways, rather than downward. The vehicle would be drawn up into the area of decrease pressure just above it, and voila, flight.
The diagrams below show roughly what I had in thoughts. The outcome looked one thing like a flying saucer — which is not surprising, contemplating that its inventor was a twelve year old boy. 
The prime view (one) exhibits rotors atop the disk spinning, which creates centripetal force that pushes air (the blue arrows) radially outward. The perspective view (2) is a schematic representation of the rotating blades. In practice a lot of perform would need to have to be accomplished to figure out the right size and form for these spinning airfoils. The side view (2) shows how air comes in at the leading and is then pushed out to the side. The partial vacuum above the car benefits in lift (the red arrow):
In principle, you could stand correct underneath one of these flying saucers and not feel any downward wind force. Of course, as they say, theory and practice are the identical in theory, but diverse in practice. I suspect that by now someone has long because had a comparable thought, has most likely attempted to construct one particular of these issues, and has realized why it wouldn’t really work.
But when I was twelve, considering about stuff like this kept me off the streets and out of trouble.
