#CosmosMagazine DNA tests on native Australians show they were one family established over 50 000 years ago, out of Africa some 75 000 years ago, and other fascinating suggestions http://lessonpeer.com/drhillteach/First%20wave%20out%20of%20Africa%20went%20to%20one%20place.mp3

#CosmosMagazine Greater internet speed, boat speeds and aeroplane lift shows that what were thought of a limits of nature can at the end of the day be engineered around http://lessonpeer.com/drhillteach/The%20fall%20of%20engineering%20barriers..mp3

#CosmosMagazine The story of a killer octopus and snails use an amazing and rapidly evolving array of toxins that are real fish (and people) stoppers. http://lessonpeer.com/drhillteach/Venoms%20evolve%20faster.mp3

This podcast guides you through an easy introduction that leads to tunneling and discrete energy levels http://lessonpeer.com/drhillteach/Quantum%20Mechanics%20Demystified.mp3

The use of a pyroelectric crystal creates an intense field when you heat it that then accelerates nuclei to a fusion collision. I love this kind of weird fantastic science. http://lessonpeer.com/drhillteach/Table%20top%20nuclear%20fusion.mp3

The solar weather is broken into space weather, a region which has features we associate with local weather and a region we associate with sea currents. http://lessonpeer.com/drhillteach/Solar%20weather%20made%20easy..mp3

You may have heard of Piezo(strain)effect but Pyro(heat)effect or Ferro(electric field)effect crystals a far less popular but absolutely captivating http://lessonpeer.com/drhillteach/Pyroelectric%20Crystals%20-%20heat%20to%20volts.mp3

It is actually a bit sad, to be honest, how we got to use the idea of bandgaps to explain conductivity and not to see the deeper side of things. Visualizing the quantum electron unlocks band diagrams as a jewel of quantum mechanics and solid state knowledge. http://lessonpeer.com/drhillteach/Metals%20Semiconductors%20and%20Insulators%20-%20upgrade%20your%20understanding.mp3
