      You really should post a correction note here or in the description explaining that you confused the heisenberg principle with the observer effect. It's the responsible thing to do.

                                1:49 to 2:27 is a bit misleading as it suggests that the uncertainty principle is a result only of the disturbance caused by observation (this is another phenomenon, known as the observer effect).

                                                          String theory is only one hypothesis on observation. We need to redirect our attention to basic fundamentals of quantum mechanics and the underlying mathematical analysis which I've recently discovered are flawed. Imagine trying to make a chocolate cake only to find out that you have no flour. No problem. Make this flourless chocolate cake: 1 cup semisweet or bittersweet chocolate chips,1/2 cup (8 tablespoons) unsalted butter, 3/4 cup granulated sugar, 1/4 teaspoon salt, 2 teaspoons espresso powder, 1 teaspoon vanilla extract, 3 large eggs
                                                          1/2 cup unsweetened cocoa powder, Dutch-process cocoa preferred. Now this is a reality we can all enjoy.
