Schrödinger’s Dog
Dear DogPhysics:
I heard that quantum
physics says particles behave
like waves. Does this mean I
have wave nature?

Double Slit
Pattern depends on distance from slits
Get alternating pattern of “bright” and “dark” stripes

Dear DogPhysics:
I heard that quantum
physics says particles behave
like waves. Does this mean I
have wave nature?
Can I use my wave
nature to help me catch bunnies
and squirrels?

Dear DogPhysics:
I heard that quantum
physics says particles can pass
right through obstacles as if
they weren’t there. Can I use
this to get through the fence to
the yard next door?

Dear DogPhysics:
I heard that quantum
physics says particles can pass
right through obstacles as if
they weren’t there. Can I use
this to get through the fence to
the yard next door?
So, I should just dig
a hole under the fence, then?
Dear DogPhysics:
I heard that quantum
physics says cats are both alive
and dead at the same time. I’ve
always known they were
undead zombie monsters! Now
my humans will have to believe
me!

Dear DogPhysics:
I am a retired quantum
physicist, and I have discovered an
ingenious quantum technique that
is worth one hundred billion dollars
($100,000,000,000). I will happily
give you 50% of this if you will
provide me with access to your
bank accounts…
