TURNING THE PAGE. " "“Out, out, brief candle!" "Life's but a walking shadow," "A poor player that struts and frets his hour upon the stage, and then is heard no more:" "it is a tale told by an idiot, full of sound and fury, signifying nothing.”" "WS. Macbeth (c. 1605), Act V, Scene 5, line 23. View in LinkedIn

AURORAL QUIRKS. “The amount of induced current in a system is not directly related to the distance to the auroral currents; the ground resistivity and the particular network configuration and its resistances have an important contribution in determining the size of the disturbance. This makes the observed induced current values highly variable from site to site and from system to system.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

AURORAL PHENOMENA. “The first observations of space weather-associated induced currents were made already in early telegraph systems more than 150 years ago. In general, being related to auroral phenomena, the geomagnetically induced currents are a high-latitude problem, affecting most regions such as the Scandinavian countries, Russia, and Canada.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

TELECOM OUTAGES. “Telecommunication devices may experience overvoltages. As optical fibre cables do not carry induced currents, space weather risks on telecommunication equipment are probably smaller today than they were earlier. However, metal wires are still used in parallel with optical cables for the power to repeat stations.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

CRITICAL VARIABLE. “However, the effects in the near-Earth environment critically depend on the polarity of the magnetic cloud, i.e., whether the magnetic field rotates from north to south or vice versa.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

FAILURE OF REDUCTIONISM. “We argue here for the recognition of functional ‘modules’ as a critical level of biological organization. Modules are composed of many types of molecule. They have discrete functions that arise from interactions among their components (proteins, DNA, RNA and small molecules), but these functions cannot easily be predicted by studying the properties of the isolated components.” https://www.nature.com/articles/35011540 View in LinkedIn

COOPERATIVE EFFECTS. “Most biological functions arise from interactions among many components. For example, in the signal transduction system in yeast that converts the detection of a pheromone into the act of mating, there is no single protein responsible for amplifying the input signal provided by the pheromone molecule.” https://www.nature.com/articles/35011540 View in LinkedIn

BYZANTINE SYSTEM. “Cells exist far from thermal equilibrium by harvesting energy from their environment. They are composed of thousands of different types of molecule. They contain information for their survival and reproduction, in the form of their DNA. Their interactions with the environment depend in a byzantine fashion on this information, and the information and the machinery that interprets it are replicated by reproducing the cell.” https://www.nature.com/articles/35011540 View in LinkedIn

THE ISSUE OF PURPOSE. “Although living systems obey the laws of physics and chemistry, the notion of function or purpose differentiates biology from other natural sciences. Organisms exist to reproduce, whereas, outside religious belief, rocks and stars have no purpose.” https://www.nature.com/articles/35011540 View in LinkedIn
