Can you be in love with a lecture series? I mean really in love, releasing all the dopamine and oxytocin-- smack dab into that nucleus accumbens-- that you release when falling in love with a human being? If so, then I am in love with this lecture series. I felt the same way about John Kricher's Ecological Planet lecture series. Maybe if it hadn't been so long since I had taken a chemistry or biology class, I would have liked this series but not loved it. There is simply nothing better in life than thinking about how matter, which makes up everything we will ever see, works. It's always magical to me. It doesn't matter how many times I learn about it -- most of this wasn't new to me, and if you have had a few courses in chem, bio, and biochem it won't be that new to you -- it blows my mind every time. I make new connections in the old material. I turn it all over and over and over in my brain and feel a continual deep sense of awe. I tried as long as I could to not finish this series because I will miss it like I would miss an old friend who moved away.
All the matter you will ever encounter is governed by the same fundamental laws of physics. David Ball put together 24 marvelous lectures to bring the magic of those laws to life. You don't need to have any background in the sciences. All that is needed is a curious mind.
Lecture series starts a bit slow. Don't give up. It gets better with each lecture.
Some questions raised by this series:
What do we know about the matter that makes up our world and how did we come to know it? What advances arose each time we discovered new elements and how to take advantage of these new elements?
Why does the term, "Shape determines function," matter and why is so awesome? (Chemicals bond in predictable ways, using simple rules. The shape of each element and each form determines how it will interact with other matter. This matters on the tiniest level possible and the largest level possible. For example, on a microscopic level, receptors reside on cells and interact with ligands (something that wants to fit into that receptor). Ligands and receptors fit together (have that have affinity for each other) when they are the right shape. You can picture a receptor meeting its soulmate ligand and saying, "You are just my type!" When they bond, because they are the right shape, they have reactions that occur on much bigger levels. The bonding of ligand with a receptor might dictate how you bond with a lover, whether you laugh or cry. On a less emotional level, you can think about how the molecules in a vitamin or a pill of medicine mimic the very shape of food or a brain chemical that can kill pain. David Ball does a wonderful job of explaining how chemist mimic different elements in food or in the brain. So good! The shape of things, big and small, allows the interactions of all the matter --which, again, is everything you will ever see in the physical world-- to occur. It is what makes everything happen, all around you, all the time.)
Why do balls bounce? (It's as simple as the shape of the molecules inside them. Balls are made of long polymers. It is simply that aspect which makes them have a rubbery surface. Rubbery surfaces bounce).
What does sugar have to do with your blood type?
How does electricity conduct and what makes a superconductors?
Why do some materials that have the same chemical formula turn out to be so different-- like how carbon can make a hard, shiny diamond or a soft, flaky graphite writing tool? Same chemical makeup but very different products. (This was the only lecture I was a tiny bit disappointed in. Pressure and temperature are some of the best magic tricks planet Earth has to shape the same elements into different products. I felt there could have been a little more awe displayed in these lectures).
How did the discovery of different materials like bronze or metal shape the building of civilization? How might they have brought about agriculture?
How did our discoveries help advance the face of medicine?
This series was filled with wonderful histories that were sprinkled throughout in just the right amount. Sometimes the histories get in the way or serve to force a tangent that steals your focus and is hard to come back from. Every history included served to really drive home the nature of matter. Absolutely wonderful series!
