    The starting point should be the assumption that Darwins natural selection can equip us with the necessary reasoning powers to do science in the first place. Since Darwinism has no use for rationality or objective truth, being only concerned with the correct behavior, what we should expect is completely at odds with what we actually experience. Until we stop promoting self-referentially inherence nonsense like naturalism/Darwinism then we will never get anywhere with this discussion.

    Hi. I'm saying this based on what you tell us at the beginning of most of your videos, that your intention is to make physics concepts simpler. Because I'm an enthusiast not a physicist, I wish you could connect this math to the real world and its impact on our lives. I give you an example: This math formula proves that quantum entanglement exists. And this is how we prove it empirically in the lab. Now that we know it exists and have the proof, this is how it can help to create quantum computers. And if you get one of these computers, you can solve problems a million times faster. I know that sounded like a silly example, but I hope that you got the idea. You know, for me the abstract math is way too abstract. I don't know why and how it connects to the real world, and what benefits the industry can take from these mathematical formulas that affects us. Thank you so much

      That is an important question! Thank you for asking - sometimes these questions are needed for understanding but are never asked so I am grateful you did! As for the script p, that is just a notation for a quantity called the electric dipole. This quantity is known as a vector, in which it has both a magnitude (length) and direction (angle). As such, we are often concerned with the scalar (magnitude) aspect of these vector quantities. So, the vertical lines surrounding the script p (|p|) indicate that we are looking for the magnitude (or size) of the electric dipole, not necessarily the direction that it is applied. This double vertical bar notation is also seen through math as an absolute value, meaning that we just want the length of the number from a set point (for example |-2| is two units away from zero). In the complex number work, we have a real part and imaginary part that can be thought of as a vector, so finding the magnitude of a complex number shows how far we are from the origin. This was a bit of a mini-lecture, so please let me know if I can help clarify anything above or add more context.

      @@curiousaboutscience Thank you so much. The double vertical lines (double pipes) is only about the scalar part, and discards the other part (being a vector direction, a negative sign which in essence can be regarded as direction on the number line, or even the imaginary part of a complex number). That's what I understood from it.

      @@SaeedNeamati Yes, I would add that this scalar part, magnitude (or length/distance) is easy to find in one dimension (number line) but would require the distance formula in the plane (complex or x-y) and higher dimensions. So, the directional parts of the vectors or imaginary parts of complex numbers aren't seen in this type of expression, but are needed via their components. What we say is that we take each component square it, add them together and then take the square root. For example: 1D: |-2|=√{(-2)²}=2 2D: Vector - a=<3,4>=3î+4ĵ=3x̂+4ŷ; |a|=√{3²+4²}=5 2D: Complex - x=3+4i; |x|=√{3²+4²}=5 or |x|=√{x*x}=√{(3-4i)(3+4i)}=√{3²+4²}=5
