Notes from the LinkedIn "Disrupting Yourself" course

Notes from the LinkedIn " Disrupting Yourself " course presented by Whitney Johnson: Disruptive innovation is a term coined by Clayton Christensen to describe a low-end or new market innovation that eventually upends an industry. The disruptors, think Amazon in the 1990s, secure a foothold at the low end of the market, and then in the pursuit of profit, gradually produce higher performance, higher margin products. Established competitors - Barnes and Noble, Borders - could aggressively counter an attack by a low-end disruptor, but they don't because it doesn't make financial sense to defend their least profitable products when they themselves could move up-market.

It has been approximated that about four hundred times more radioactive material was released from Chernobyl than by the atomic bombing of Hiroshima and Nagasaki. How does a nuclear reactor work? As explained in the HBO mini-series Chernobyl by the character playing Valery Legasov, Chief of the commission investigating the Chernobyl disaster who later exposed the design flaws - A nuclear reactor makes electricity with steam. The steam turns a turbine which generates electricity. Where a typical power plant makes steam by burning coal, in a nuclear plant, we use something called fission. We take an unstable element like Uranium 235, which has too many neutrons. A neutron is, (like a) bullet. So, bullets are flying off of the uranium. Now...if we put enough uranium atoms close together, the bullets f...
