Previously I mentioned that in my school days the sciences were taught so as to never kindle any interest in me. Our teachers seemed more interested in laying traps (Gotcha!) than in imparting knowledge. I thought of physics and chemistry as bitter-tasting medicine that had to be swallowed. No more.
Nowadays sciences which were strictly separate seem to have coalesced and melded together. Jared Diamond’s “Guns, Germs and Steel” combines anthropology, history and geography. Diamond links the human trajectory through time and space to climate, terrain , invasions, scientific discoveries and other unpredictable elements.
Evolutionary biologist Richard Dawkins is an Oxford Professor of Public Understanding of Science and an excellent teacher with a gift for making the esoteric comprehensible. I like his proposition that we humans are only the disposable wrapping that allows our genes to travel on without us. I think that is what immortality really is.
Neil DeGrasse Tyson is an astrophysicist and director of the Hayden Planetarium at the Natural History Museum in New York. He follows in the footsteps of Carl Sagan whose television show Cosmos helped to debunk the idea that we humans are at the center of the universe. Sagan showed that we and our planet are but a tiny dot in the immensity of the cosmos. Tyson notices children’s natural curiosity about the world and observes how it can be drummed out of them by making them adhere to a structured way of learning. This famous scientist encourages daydreaming.
I now leave the familiar sphere altogether with Physicist Lisa Randall. She explains dark and light matter, black holes and introduces us to the Large Hadron Collider which reenacts the Big Bang by accelerating particles and simulating the birth of the Universe. She also explains the recent discovery of Higgs-Boson, an elementary particle that gives other particles their mass and is sometimes called the God Particle. In her latest book she explains how meteorites deposited the seeds of life on earth, and how the dinosaurs disappeared making possible the birth of mammals.
My mind is stretched to its outer limits. Dizziness is imminent as I am desperately trying to hold on to these new ideas. I shall stop with this slippery and elusive knowledge before it totally eludes my grasp.
In Part 4 I will attempt to understand time/space and dwell on our very limited senses.
