Much easier to clean and sharpen a single blade, is my guess.
Also, even with a +, maybe the cheese would deform in the center area due to combined displacement from 2 blades

Oh wait were you asking for a reason to use 'is' on immutable types like int and str? I really can't think of one, unless you're writing test code that's intended to check specific python behavior.

... So before modifying it you can do
if arr_local is arr_in:
# avoid changing arr_in
arr_local = arr_local.copy()
This avoids doing any copy when not needed.
If you *always* need to modify arr_local, can instead just pass "copy=True" to np.asarray to force a copy.
if arr_local is arr_in:
# avoid changing arr_in
arr_local = arr_local.copy()

A function which needs to work with numpy array of float32: it could start with
arr_local=np.asarray(arr_in, 'float32').
If arr_in is already float32, this just returns the same array.
Now, sometimes it needs to modify elements in arr_local, but we don't want to change the contents of arr_in...
arr_local=np.asarray(arr_in, 'float32').
If arr_in is already float32, this just returns the same array.

Using 'is' to compare two lists will tell you if the lists are really the same object, so that modifying one var will modify the other, which can be very important to know.
Likewise for dicts and class instances.
For immutable types like int and str, it would be very unusual to want 'is' vs '=='.

And I'm pretty sure both would be true if it was run from a .py file (rather than interactively), since the 'compile' operation detects duplicate literals, and only uses one instance of each distinct value.
'Safer' (?) example would use something like :
a=1000
b=abs(-a)

Sure, I'm asking about the design, as opposed to the animation. Elsewhere on the thread I think I read that it rotated geosynchronously, at geosynchronous altitude, which would appear to be in conflict with "not rotating".

You're saying the structure we see is not rotating, but there is mass inside the tubes zooming around to keep it up?

Physics of the crash seem very plausible. But yeah, the pointy curb corners? Unless it's a place to make a U-turn (that the driver may have suddenly thought would work), but to definitely not allow the opposite U-turn.

Remembering when I took my daughter, about 5, to the Ontario Science Center, there was an exhibit with 'normal' and 'very pregnant' sagittal section models. I held her up and said, "this is what happened to Mom's organs when you were in her. Look, it's all squished up".
She laughed out loud.
