Good science jokes

I once got a complex blowjob.
The orgasm was imaginary.
But I still would up with residue.

What am I?

I move when the timing is right.
Whatever path works is okay for me.
My favorite past-time is humming.
I like to interact with others.
I am unsure what I will become.

What am I?

Who am I?

I put something inside something else.
Next, something strange happened.
Something new came out of the something else.
And now, I am here.

Who am I?
