Less one, the rest have been answered and I'm afraid you didn't get any others. This is not correct but has not been answered correctly.
Question 18: How do you generate a purely random number using nothing but computer software [if you write a program in C or Visual Basic, for example]
Very good! https://en.wikipedia.org/wiki/Conjugate_variables Derivatives of action In classical physics, the derivatives of action are conjugate variables to the quantity with respect to which one is differentiating. In quantum mechanics, these same pairs of variables are related by the Heisenberg uncertainty principle. The energy of a particle at a certain event is the negative of the derivative of the action along a trajectory of that particle ending at that event with respect to the time of the event. The linear momentum of a particle is the derivative of its action with respect to its position. The angular momentum of a particle is the derivative of its action with respect to its orientation (angular position). The electric potential (φ, voltage) at an event is the negative of the derivative of the action of the electromagnetic field with respect to the density of (free) electric charge at that event.[citation needed] The magnetic potential (A) at an event is the derivative of the action of the electromagnetic field with respect to the density of (free) electric current at that event.[citation needed] The electric field (E) at an event is the derivative of the action of the electromagnetic field with respect to the electric polarization density at that event.[citation needed] The magnetic induction (B) at an event is the derivative of the action of the electromagnetic field with respect to the magnetization at that event.[citation needed] The Newtonian gravitational potential at an event is the negative of the derivative of the action of the Newtonian gravitation field with respect to the mass density at that event.[citation needed]
I just figured momentum is mv, energy is m (times a constant), so it becomes a question of what times velocity gives position.
LOL! Well it turns out to be a profound relationship. Heisenberg's Uncertainly principle tells us the limitation on the knowledge we can have about the momentum and position of a particle. There is an identical relationship between energy and time and all of the conjugate pairs listed above
Question 19: They say you can't get something from nothing. But you can get nothing from two somethings. What relatively easy demonstration allows you to add two somethings together and get absolutely nothing?
I read you can build an inexpensive RNG with a lava lamp. https://www.popularmechanics.com/technology/security/news/a28921/lava-lamp-security-cloudflare/
Write something 'real world' into the algorithm that the program can factor into the equation, like 'how many times the word 'the' was included in a google search in the last 5 seconds' or something.
Positive and negative numbers (assuming 'zero' counts as nothing, but I dunno if it technically does, because its still a 'digit').
Q21: If you have a helium balloon floating around in your car and you hit the gas, what happens to the balloon, and why?
