    The audio recordings of the Feynman Lectures on Physics (1961-64) are now publicly available. Don't be discouraged by the quality of the recording of Lecture #1, which is damaged. The quality of the rest is pretty good. feynmanlectures.caltech.edu/flptapes.html

    Stephen Hawking 1942-2018. A great physicist, of course, and also a great man who inspired millions. I'll remember the sharp wit and twinkling eyes; he never took himself too seriously. His friends will miss him terribly.

    Steven Weinberg 1933-2021. One of the most accomplished scientists of our age, and a particularly eloquent spokesperson for the scientific worldview. Steve remained intellectually active to the end. An immeasurable loss.

    The pioneering work of Clarke, Devoret, and Martinis showed that very cold electrical circuits behave in ways that exhibit fundamental principles of quantum physics. Building on this achievement, Devoret, Martinis, and many others are constructing quantum computers, powerful

    Someone asked: What are the most important ideas in physics over the past 30 years? Three immediately came to mind: The holographic principle, topological order, quantum error correction. What's lovely is that these three ideas are so closely related.

    From her 1993 PhD Thesis @Caltech: "I dedicate this thesis to all the women scientists I have known." Andrea Ghez is a superb spokesperson for science --- no doubt she will be an inspiring role model to many future scientists.

    “I hope I can inspire other young women into the field. It’s a field that has so many pleasures, and if you are passionate about the science, there’s so much that can be done.” - Andrea Ghez speaking at today’s press conference where her #NobelPrize in Physics was announced.
