Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa

Questions include: Is it possible to create more universe? - Why does running my Waterpik interrupt Bluetooth connections? - In third grade, I had an argument with a teacher. She said, "Before humans had language, they thought just like us." I argued that couldn't be true–instead, language gave way to complex thoughts. Was I right? - Why do many medications have side effects? - Why do we yawn? Are yawns truly contagious? - Why do cats meow, why do dogs bark, why do birds chirp? - Why can't AI help us to analyze animal sounds? - Do photons run through antimatter? Does that make them matter? - Is chemistry really just physics? - Does brain size have any correlation to IQ? - Well, the hardware of the brain is an ongoing process, especially in childhood. Nurture, environmental, social and natural circumstances can cause changes in brain hardware. - Do bigger brains actually have more functional neurons, or are they just more spread out? - Would all whales speak the same whale language?
