OXYGEN, CARBON, HYDROGEN, NITROGEN. “There are 92 naturally occurring elements on Earth, from hydrogen to uranium, so why do these four make up such a majority of living things? Part of the reason lies in the fact that they are versatile elements, capable of producing a vast array of chemical compounds, but it also has to do with the fact that they are among the most abundant elements in the universe.” https://lnkd.in/eJ_9fKE View in LinkedIn

PERCENT OF BODY WEIGHT BY ELEMENT. Oxygen: 65%; Carbon: 18.6%; Hydrogen: 9.7%; Nitrogen: 3.2%; Sulphur: 0.05%. These elements make up 96.5% of your body weight. https://lnkd.in/eJ_9fKE View in LinkedIn

TOP 20 ELEMENTS OF THE UNIVERSE (number per million atoms): Hydrogen: 930,000; Helium: 72,000; Oxygen: 800; Carbon: 500; Neon: 80; Iron: 20; Nitrogen: 90; Sulphur: 20. https://physics.info/nucleosynthesis/ View in LinkedIn

THE TWO OLD BIGGIES. “Almost all the hydrogen and helium in the universe today were created in the first three minutes after the big bang. All of the other naturally occurring elements were created in stars.” https://physics.info/nucleosynthesis/ View in LinkedIn

MORE THAN THE MOST ABUNDANT. “More than ninety per cent of the universe is composed of hydrogen and helium. Both elements have been around since shortly after the beginning of the universe. Yet, hydrogen and helium together won’t make anything as complex as the Earth, or a bacterium, or a refrigerator, or you and I. To do that, we need carbon and oxygen and nitrogen and silicon and chlorine and every other naturally occurring element. All of the other naturally occurring elements were created in stars.” https://physics.info/nucleosynthesis/ View in LinkedIn

MODULAR VS MONOLITHIC. "Intuitively, modular systems seem more adaptable, a lesson well known to human engineers, because it is easier to rewire a modular network with functional subunits than an entangled, monolithic network." https://lnkd.in/eX5AfaH View in LinkedIn

THE UNIVERSE FLOWS THROUGH US. “We are not in any way separate from the rest of the universe. Instead we borrow a tiny fraction of its atoms for a few years, incorporate them into the patterns of life, and then are forced by the inexorable laws of entropy to release them again.” http://www.science20.com/stars_planets_life/where_does_everything_come_life_and_death_stars View in LinkedIn

NETWORK NODES. "Networks are modular if they contain highly connected clusters of nodes that are sparsely connected to nodes in other clusters." https://lnkd.in/eX5AfaH View in LinkedIn

ANCIENT ATOMS. “The atoms of carbon, nitrogen, oxygen, sulfur and phosphorus that comprise life on the Earth were once in the center of stars like our sun, forged at temperatures hotter than any hydrogen bomb. Most of the hydrogen atoms in living organisms are as old as the universe, which burst into existence 13.7 billion years ago when time began.” http://www.science20.com/stars_planets_life/where_does_everything_come_life_and_death_stars View in LinkedIn

MODULAR NETWORKS. "Many biological entities are modular, especially the many biological processes and structures that can be modelled as networks, such as metabolic pathways, gene regulation, protein interactions and animal brains." https://lnkd.in/eX5AfaH View in LinkedIn
