google is alive
Bookmarked 712 weeks ago
in which hank attempts to define what life is argues that google is in fact alive albeit poorly and then proves that individual lives have no or extremely little value for their own sakewith mouthwash to be clear:1 i am not arguing that google should be treated like a sentient life form if google is alive it039s alive the same way a virus is the fact that it039s alive does not change its ethical status it is very interesting though2 while i don039t value the individual lives of the bacteria in my mouth i value quotlifequot tremendously and believe that one bacteria in a world otherwise devoid of life would be the most precious thing on that world but seeing as how there are trillions of bacteria within four feet of me right now i039m not particularly concerned with their welfare so quotlifequot is not a good qualification for quotvaluequot3 i have done some further research and it appears that the mrs gren thing is not so much criteria for life though they are often referenced as criteria for life it039s more like quotpropertiesquot of lifeas we know it i039m less interested in describing life than i am in determining what makes one thing alive and another thing not alive describing what we039ve got is easy deciding the status of something that may or may soon exist is an entirely different matter4 i039m very interested in people039s thoughts about about the quotwantquot theory though obviously this is a loose definition of quotwantquot does a plant really quotwantquot to turn toward the sunno what i039m saying is more quotreacts to it039s surroundings in order to fulfill its needsquot but quotlife wantsquot just sounds so much better the question of whether google or fire for that matter is reacting to its needs in order to fulfill its needs is an interesting one but i don039t really think that computer programs quotwantquot they don039t have needs they have instructionsbut how different is that from the instructions that bacteria have from their genesfinally google does satisfy schrodinger039s criteria of increasing order using available energy i think schrodinger039s criteria is in fact better than mine since you can039t argue that fire meets it as fire increases entropy and it makes me feel as if google is in fact alive however using this criteria one could also argue that an automated factor that turns plastic into toys is also alive as it would be using energy to decrease entropy if it is truly autonomous though that almost seems as alive as a virus to me

chaos theory on quotit039s only a theoryquot with andy hamilton and reginald d hunter
Bookmarked 772 weeks ago
i thought this might interest a few of you obviously they don039t go into any great depth but the professor explains enough of the basics of chaos theory to make this worthwhile viewing the idea of this program is that professors come in and defend a chosen theory to the panel which is then accepted or rejected by vote it039s on bbc4 for those who want to knowby the way that compound pendulum is badass i need to get one

how to time travel

brian greene professor of physics and mathematics at columbia university and co-founder of the world science festival explains what we know about time travel so far following is a transcript of the videobrian greene: im brian greene professor of physics and mathematics at columbia university and co-founder of the world science festivalit039s critical that you realize that there are two types of time travel and they are radically different time travel to the future definitely possiblewe know how to do it because einstein showed us the way over a hundred years ago its surprising how few people actually really know about this in their bones he showed that if you go out into space and travel near the speed of light and you turn around and you come back your clock will be ticking off time more slowly so when you step off it039s going to be the future on planet earth you will have time traveled into the futurehe also showed that if you hang out near a nice strong source of gra

colors of light and their wavelengths - science for kids educational videos by mocomi
Bookmarked 387 weeks ago
http:mocomicom presents: the colors of lightin a broad sense of the word sunlight is white the sun emits a spectrum of energy that includesx-ray ultraviolet radiation visible and infrared light and even radio waves the visible light section of sunlight is made up of all the colours of colour spectrum ie a mixture of red orange yellow green blue indigo and violetthe reason we don039t see sunlight as seven colours is because when the wavelengths of the primary colours interact with each other white is produced an easy way to see how this works is with the help of a prism when white light enters a prism it bends and separates due to a phenomenon called dispersion red light has the highest wavelength and therefore a lesser frequency and violet has the oppositeto learn more about the colours of light read: http:mocomicomcolours-of-light for more such cool physics articles and videos visit: http:mocomicomlearnsciencephysics follow mocomi kids

paramagnetism of oxygen
Bookmarked 719 weeks ago
oxygen gas is condensed into liquid form and then poured between the poles of a strong magnet so we can observe its paramagnetic propertieswe send o2 gas through a copper coil which is then immersed in about 2 liters of very cold--77 degrees kelvin liquid nitrogen as the o2 travels through the coil it loses enough heat to change from a gas to a liquid and that liquid is collected in a small pre-cooled dewar liquid nitrogen is poured between the poles of the permanent magnet but since its diamagnetic properties lead to only a very weak interaction with the field it just sloshes through as if it were water the liquid oxygen on the other hand sticks between the poles of the magnet until it boils away because the oxygen molecule has an electronic structure that favors the non-cancellation of two of the electron spins its net magnetic moment is free to point in the direction of an external magnetic field just as a compass needle does when enough of these moments are aligned the material as a whole behaves like a single magnet at room temperature only a small fraction of the moments are able to line up perfectly with the external field but when oxygen is cooled and condensed into a liquid the effect is more noticeablefor more details on our setup see:http:sciencedemonstrationsfasharvardeduicbicbdokeyword=k16940ampamppanel=icbpagecontent2173903ar2413fname3dindepthhtml2cicbpagecontent2167563ar2413fname3dindepthhtmlampamppageid=icbpage91943ampamppagecontentid=icbpagecontent217390ampampstate=maximizelike us on facebook http:wwwfacebookcomnatscidemos
