    So, in a way does that mean that people with lower pitched voices just have "weaker" or "slower" vocal cords because they're moving air slower than the vocal cords of someone with a higher pitch voice? Or is this concept different when referring to just the regular voice of a person.

    Oh, hi Mark! I like your humble approach to photosynthesis and biologic sciences in general, it says you know what's going on. To me the saying "knowing things takes the magic of it" seems like a missconception about a missconception. Compared to other fields (and always, with caution trying to make fair comparisons) advanced biology it's a very chaotic, emergent, integrative and with many no-answers field. Just the example about how an organism derivated from LUCA started using the energy from the sun in the most efficient way, invaded Pangea and became the most prolific organism on the entire planet, with complex mechanism and variability to reproduce itself wich involves a co-dependent evolution with other movil species such as animal kingdom, to end being the freaking plant ripping the water molecule and bringing oxygen we know from school. The more you know about specifics of photosyntesis, the more impressive it becomes (and the same goes to microbiology in general). I also appreciate your exposition about going live, you are going well. Congratulations about this initiative and keep it up.

    Mark, you are amazing and I love your enthusiasm and edited videos. Practice these lectures at least 3 times as many times as you have in front of a mirror, or take some improv classes. I am not trying to be discouraging, but its not about how many people are watching. It's about your confidence in the lecture you are presenting. The better you know exactly what you want to present and how, the better it will be received and absorbed.

    The frequency doesn’t change, the amplitudes on the harmonics are modulated so that you weight higher frequencies more (in the case of He).

    the specture specture2 ditë më parë

    Maybe because helium is less dense than the air, so it always want to float up because the buoyancy force of the air is pushing it upwards. Hence the sound or the vibrated molecules from mouth will always move upwards and sometimes knocking with your vocal cords or the pinch or frequency is disturbed because it is moving upwards really fast which cause your voice deeper or higher.
