You have clearly never driven on 93 through Boston where the person you replied to said they are from (aka the Big Dig). It is basically an entire highway that is underneath the city. There are many on and off ramps, lanes suddenly become exit only, complex multi-lane exits that branch…it’s intimidating. As somebody that has lived in the Boston area for 15 years now, I still mess things up.

Official response from Greg Bernhardt

It’s years since I last used PhysicsForums, but found it immensely useful in the old days while going through my undergrad physics degree (it was less useful for PhD courses). I am not morally opposed to providing AI attempts at an answer in threads where nobody else chimes in. However, using real accounts that belong to other users is wildly over the line. I was surprised to see this wasn’t really called out in the official response thread by the existing users as that is the part of all this that is the most egregious to me.

I have a PhD in and am a practicing physicist in the field of rheology. I think this is an interesting way to explain viscoelastic materials to people. My go-to example is usually Silly Putty, but cats are something that just about everybody has some experience with.

I wrote my PhD thesis about bacterial flagella. Not about the motor though (which is incredible), but about the long part of the flagella that is extracellular. It is able to change its shape as the bacteria moves. The mechanism by which this happens is at the same time quite simple, but just about impossible to explain via text. Really, really neat bit of evolution that has proven to be home to incredibly rich physics that is still being studied to this day.
