Nuclear energy might be a failed experiment. In over sixty years the technology has not only failed to keep its promise of cheap, clean and safe energy, it also caused major catastrophes and enabled more nuclear weapons while the nuclear waste problem is still not solved. The video "3 Reasons Why Nuclear Energy Is Terrible! 2/3" is a resource included in the Physics topic made available from the Kurzgesagt open educational resource series.

Different cells have different needs. Some are aerobic – they need oxygen – while others are anaerobic and don't need oxygen. But the lifecycle of almost all cells follows a predictable 4 phase-pattern. Lag, Exponential, Stationary and Death. When a cell is first introduced to fresh growth media, it has to adapt to the new environment. This creates a lag in the growth timeline. After the organism adapts, the batch takes off. The cells begin dividing at a constant rate –an Exponential or Logarithmic increase. But eventually, the nutrients in the media are consumed, toxic metabolic waste products build up, cells begin to die, and growth slows. When just as many cells are dying as are dividing, the batch enters the Stationary phase. This is the point at which the key nutrients are completely consumed, the fermentation is stopped and the broth is harvested. If the fermentation were allowed to continue, the cells would enter the Death phase.
