About
Smart Nonsense is where your astrophysicist friend (Henry 👋) explains complex technology in a simple way. Each video starts with something that seems obvious -- your phone, the internet, an airplane -- and asks a few more questions: how does this actually work? why is it that way? Okay, but WHO decided it had to be like THAT?? From there, it unravels the hidden logic using simple, beautiful explainers anyone can follow. Behind the channel is Henry Belcaster, a Brown-trained astrophysicist who believes the world is far more interesting than we give it credit for -- we just stop asking 'why?' He’s joined by Derd, a blue alien co-host who isn't afraid to ask "dumb questions", makes the wrong assumptions, and helps us figure out the world together. --
