"Humankind cannot gain anything without first giving something in return. To obtain, something of equal value must be lost. That is alchemy's First Law of Equivalent Exchange."A quote I came across while researching energy and found a sort of fantasy version of energy manipulation. Now on a more serious note, at least pertaining to the assigned post due; someone in class mentioned a light bulb on for over 100 years. It is a hand-blown bulb with carbon filament. Approximate wattage-4 watts. Left burning continuously in firehouse as a nightlight over the fire trucks it has now reached it's 109th continuous burning year. Just thought I would give some insight into this since I thought it was a myth at first. For more facts and research done go to http://www.centennialbulb.org/facts.htm

"They don't make 'em like that anymore." I thought this was pretty interesting. I'm surprised that, after all these years, the firemen haven't accidentally broken it while throwing a football around in the firehouse. But in all seriousness, this bulb must be unreasonably durable-especially the filament. The temperature of a burning carbon filament can reach a few hundred degrees F if I'm not mistaken, and the fact that this bulb's filament has been at that temperature for over one hundred years just baffles me. I would say that someone should investigate how this bulb is put together to see how it varies from the bulbs today, but obviously that would endanger breaking or turning off the bulb which would probably be frowned upon by a few people.
ReplyDeleteWhen i saw the word alchemy this blog caught my attention immediately. The idea of alchemy is so grand and fantasy-like yet people forget it was a very popular science topic for many years in the past. The idea of creating gold by adding photons to a more common element sounds bizarre yet plausible. How hard can it be to add 1 single proton to an element? Apparently even with all the energies we can produce today can't perform this task.
ReplyDeleteAncient and fantasy-like as it may be, that law of alchemy certainly seems to have significant implications for our current (or any) situation!
