My memories of my time in high altitude astronomy indicate that there were no oxygen concentration monitors or alarms in the areas that liquid nitrogen was in use at the high altitude astronomical facilities where I had worked. - Steven Magee
During my time in high altitude astronomy, I routinely witnessed workers breathing medical oxygen, industrial carbon dioxide, nitrogen and helium gas as part of their daily work routine. - Steven Magee
This is what works for me: I practise crop rotation with my creative endeavours. I’ve found that when the nitrogen runs out in the soil in one field, it’s best to leave it fallow for a while and cultivate another. - Andrew Macrae
We have calcium in our bones, iron in our veins, carbon in our souls, and nitrogen in our brains. 93 percent stardust, with souls made of flames, we are all just stars that have people names. - Nikita Gill
