Dirac: 1975, New Zealand (h/t to +Igor Khavkine) 
Dirac Lecture 1 (of 4) - Quantum Mechanics
Dirac Lecture 2 (of 4) - Quantum Electrodynamics
Dirac Lecture 3 (of 4) - Magnetic Monopoles
Dirac Lecture 4 (of 4) - Does 'G' vary? (Large Numbers Hypothesis)

These look like a total treasure. I've never heard Dirac's voice before, which is awesome by itself, but these also appear to be great lectures as well from what Ive seen so far. Take a listen to this giant of physics and co-father of quantum mechanics...

Funny, there is so much fuzz and distortion in the first minutes of the lecture they seem to give it a kind of 'quantum' feel. ;]

I also really like Dirac for being one of the earliest champions of the theorists's perspective (for lack of a better name) that I subscribe to, and whose best modern day proponent is Nima Arkani-Hamed. Dirac said things like:

The most powerful method of advance [is] to perfect and generalize the mathematical formalism that forms the existing basis of theoretical physics.

And:

One must be prepared to follow up the consequences of theory, and feel that one just has to accept the consequences no matter where they lead.

(As quoted from http://arxiv.org/abs/hep-th/0304042 )

There is a great bit in this lecture (starting around 17:00) about his efforts to try to understand the non-commutation of quantum operators, and how this hinged on identifying the appropriate concept from classical mechanics, the Poisson bracket. Just like Nima loves to talk about, this is a great example of the major hint for the next layer of understanding lying right there in the existing framework.

Dirac made enormous contributions to the understanding of quantum mechanics, including the very language we use to describe it. He generalized the simple bosonic wave equation, the Klein-Gordon equation, to a fermionic version, the Dirac equation, which predicted antimatter. And his monopole quantization condition plays a key role in grand unified theories, the topological aspects of gauge theories, and their confinement, and might well explain the quantization of charges we observe in the universe. And the list could be significantly elaborated...

One person always comes to my mind whenever I hear this fantastic song
Happy Birthday, Eric Clapton
Written for his wife Pattie... as he was watching her get ready to go out one evening.

On this day... 1964
Happy Birthday, Tracy Chapman
When the then unknown Tracy Chapman was booked to appear down the bill at the Nelson Mandela birthday concert at Wembley Stadium on June 11th 1988, little did she know her appearance would be the catalyst for a career breakthrough. After performing several songs from her self titled debut during the afternoon, Chapman thought she'd done her bit and could relax and enjoy the rest of the concert. However, later in the evening Stevie Wonder was delayed when the computer discs for his performance went missing, and Chapman was ushered back onto stage again. In front of a huge prime time audience she performed "Fast Car" alone with her acoustic guitar. Afterwards the song raced up the charts on both sides of the Atlantic, and in 1989, she won the Grammy for Best Female Pop Vocal Performance.

_ "It's not really about a car at all... basically it's about a relationship that doesn't work out because it's starting from the wrong place."_ - Tracy Chapman
