I'm an engineering student & member at mathtutordvd. I practice math with your videos almost everyday❤ i just want to say THANK YOU, i would not make my dream of becoming a engineer without your videos ❤ this new channel is amazing, I watch as much as I can in my free time! A wish would be to see a video about solar energy 🌄 I wish you the best 😊❤
Hi i am a sound engineer, so may be i am biased. But i blv that, i would call it a sound. There was sound bcoz the action generated the frequencies within the audible range of human hearing. However there is no one to receive those frequencies to call it a sound. But the sound existed there for those moments, as those vibrations were within the hearing spectrum. We call any vibration happening thru a medium between 20Hz-20KHz above 20 micro pascals of pressure a 'sound'.
Yes! It all comes down to how one defines the concept of 'sound'. I loved the scientific approach to this age old (at least, I assume it is age old) philosophical question
