Why are the 50% I reveal when signing random?
Sample how one-time signature works
Perhaps it helps with a short sample. Assume we are in a world where you do not need 384-bit security, but only 8-bit security (to make the example shorter). And I'...

Short answer: No.
Long answer: Whether a public key can be used for encryption, verifying signatures, or both, heavily depends on the used cryptographic algorithm.
RSA is an algorithm where the same ...

What happens when I send a transaction to myself?
Nobody knows that you are sending iotas to an address that was generated from the same seed, so the steps when you do that or you when send iotas to a third party are exactly the same.

Is part of the address private key revealed when the user reattaches a failed transaction?
You cannot get parts of the private key using reattachments. To understand why, let's see how signing works.
First of all, there is an unsigned bundle consisting out of several transactins. To sign ...

If the bundleHash is normalized how is the private key is revealed
Your private key consists of a series of "chunks". The public key is generated by hashing each chunk 27 times.
So, 27 times hashed is considered public.
Every chunk that is hashed less than 27 times ...

What to do with pending transactions even after too many reattachments?
You must keep promoting the pending transaction. You should also select a properly sync fullnode. (see http://iota.dance/nodes/).
As you mention yourself, sending to a different address is a double ...
