GREAT video. Great explanations of temps and gradients. Too many people use what I call "innappropriate precision". This would you saying the floor was 58.7 F , but you properly said "about 60 F".
I used to HAMMER my graduate students on this as they typically confuse quoting ten significant numerals as better "precision" in an environment where the reading was +/- 20% of reality.
Clear, well edited and done well.
What is next?
