This is one of the few working models of this famous machine in captivity. It belongs to Enigma expert Dr Mark Baldwin, who demonstrated it after his talk on 2008/03/12 at Napier University, Edinburgh.
It was the addition of the fourth rotor to the original 3-rotor Enigma which mutliplied the coding possibilities to such an extent that Alan Turing's electromechanical "bombs" were no longer up to the job of exploring encryption possibilities in order to decode the coded U-boat communications. The famous pioneering Colossus computer was required.
Unfortunately because of the role Colossus played in the war and military cryptography considerations of national security kept the details of this very important milestone in the history of computing a secret for thirty years, and the hobbling of Alan Turing's post-war computing career and his general harassment by the security services led to his suicide.
It was a great privilege for me, having spent over forty years working with computers, to be so close to such a historic machine. This was the best photograph I could snatch in limited time of this machine in a hurry in very crowded conditions. Although the popup autoflash seriously overexposed it (must remember to turn that down!), it's better than my previous one, taken through glass at an exhibition, although that one does also show the rotors and the front plugboard.

I was in the RAF from Nov 1993 to Dec 2000. These pictures are from my trade training days at RAF Locking near Weston-Super-Mare, 9 Feb 1994 - 1 Aug 1994. I was on course TCO 114.
At RAF Locking I was trained as a Telecommunications Operator (TCO). A TCO mainly worked in Communication Centres or Signals Unit's, operating a variety of telegraphic, cryptographic, radio, and Morse equipment. TCO's were also trained as Telephonists where they worked in station telephone exchanges. TCO's could also serve in a field comms role at Tactical Communications Wing (TCW) RAF Brize Norton, a role in which I served in early 1998.
I later returned to RAF Locking in 1997 to undertake my Morse course (3 Mar 1997 - 10 Jun 1997); I was on QMC 41.
The operational units I served at were:
RAF Waddington
TCW, RAF Brize Norton (detached to Bahrain)
RAF Coningsby

A series of already existing books, i designed them for a university brief just after Christmas but been trying to keep myself busy so i decided to re-design them and im much happier with this set.
P.S. The old set is still on this account have a look and see what you prefer but i'm sure everyone will think these are better, i hope anyway.

San Diego, Calif. (Jan. 26, 2011) – Frank Davoli, a subject matter expert assigned to the Navy Information Assurance and Cyber Security Program Office (PMW-130) demonstrates the tactical key loader (TKL) cryptographic key fill device at the Armed Forces Communications and Electronics Association (AFCEA) Western Conference and Exposition (West 2011). The fielding of TKL will ultimately enable forward deployed warfighters to quickly and discreetly load End Cryptographic Unit (ECU) well into the 21ST Century.U.S. Navy photo by Rick Naystatt/released

The blockchain is an unquestionably resourceful invention; it has created an innovative backbone of the financial transaction procedure. It is actually a growing list of various records known as blocks, and those are linked using the cryptography.

A simplified (two-character version: Q and P) electrical diagram of Enigma. The top left shows the three rotors that swap letters in and out. The bottom left is the Stecker which is basically a variable way of swopping letters. The rotors change position on every keystroke and the Stecker (Plug-board) remains the same. The lamps on the right are those that light up when a key is pressed.
The fixed reflector sends the electrical signal back through the rotors. This meant that at the same point in time (when the rotor settings are identical), typing in an non-coded character would give you the coded character to use, and also vice-versa - typing in the coded-character revealed the non-coded character.
So the same Enigma machine was used to encrypt and decrypt messages. The operator just needed to know the rotor settings and the Stecken letter-combinations.
Everyday the German military would chose 3 rotors out of a set of 5, specify each of the rotor-settings and start points and define 10 pairs of letter combinations for the Stecker. The Stecker drastically improved the security of Enigma over it's pre-war commercial variant.
The moving of the rotors is not shown in this diagram because it was done mechanically. It ocurred just before a key was depressed, so happened before the electrical circuit was completed.

Normal daily life along a different timeline - which we cannot find - but have the feeling that it exists - but
Certainly!
Quantum computing represents a groundbreaking advancement in technology, deeply intertwined with the concepts of superposition, entanglement, and interference from quantum physics. Unlike classical computing, which processes information in a linear fashion using bits (0s and 1s), quantum computing utilizes quantum bits or qubits that can exist in multiple states simultaneously. This enables quantum computers to perform numerous calculations at once, effectively navigating through a vast landscape of potential solutions.
The idea of parallel timelines can be likened to the way quantum computers operate. Each decision or computation can be viewed as branching into multiple outcomes, similar to how different timelines might unfold based on various choices. This means that a quantum computer can explore various paths to a solution simultaneously, leading to remarkable efficiencies in solving complex problems.
In practical terms, this capability could revolutionize fields such as cryptography, where quantum computers may break existing encryption methods faster than classical computers. In material science, they could simulate quantum phenomena to discover new materials with desirable properties. Additionally, in optimization problems across various industries, quantum computing offers the potential to find the most efficient solutions more rapidly than traditional methods.
In summary, the link between quantum computing and the concept of parallel timelines highlights a fascinating intersection of technology and theoretical physics, suggesting that our understanding of reality may be more complex and interconnected than we previously imagined.
