Nobel Laureate physicist Leon Lederman takes a hard look at science education. The crisis in science education (pre-K--14) has been widely recognized at least since the report "A Nation at Risk" was published in 1983. This report accompanies a huge number of later reports all read and appreciated but never implemented. There is good reason for new optimism, but the persistent failure to implement the well understood cures must be understood before we can capitalize on the accumulating wisdom.

Leon Lederman was co-winner of the Nobel Prize in Physics in 1988. He recalls his life after being discharged from the U.S. Army after WWII. From a returning troop ship docking at the Battery in New York, he hastened uptown to register as a graduate student in physics at Columbia University. His story sketches major events from there to the Nobel Prize celebration for the discovery of the muon neutrino, proving that there are at least two families of neutrinos.

No mystery is bigger than dark energy — the elusive force that makes up three-quarters of the Universe and is causing it to expand at an accelerating rate. Join a panel of Lawrence Berkeley National Laboratory scientists who use phenomena such as exploding stars and gravitational lenses to explore the dark cosmos.

Conversations host Harry Kreisler welcomes Nobel Laureate Leon M.

Lederman. Tracing his intellectual journey, Professor Lederman discusses the qualities of a scientist, the early years of particle physics, the evolution of his own research interests, the discovery of the muon neutrino, the importance of that discovery and its implications for cosmology. He recalls the dynamism and excitement of his years in particle physics and the experience of winning the Nobel Prize. Drawing on his recent work, Professor Lederman also offers a critique of Secondary school science education and calls for a transformation of the curriculum.
