Science & Technology Q&A for Kids (and others) [September 6, 2024]

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: Can machine learning find a pattern in all animal languages? - Cat: "Meow." Translation: "What a glorious day to be alive. I think I will frolic in the fields and catch myself some field mice for my tea. Then I shall sit down and ponder the nature of the universe." - What is time? - ​​If the rules repeat a state, does that mean time has gone backwards? - ​​​​So less computation allowed for the progression of time? Time slows down the faster you go? - Communication speed between Mars and Earth is not instantaneous. So wouldn't both the sender and the receiver never have real-time data of what was happening on both planets? We on Earth may only find out that something terrible happened on Mars after it's too late, correct? - ​​Is there an "objective" time in Wolfram physics? Is the "frame rate" the same everywhere? - How do I prove that matter is made of atoms? - How would you solve 100/4(2+3)?
