The experiment was first demonstrated in 1863 by British Engineer William Armstrong.</p> <p>Two containers of deionized water, placed in some sort of insulator (glass beakers work fine), must be connected by a thin thread and exposed to a high-voltage charge (one beaker receives the positive charge, and the negative to the other.) At a critical voltage threshold, a water bridge forms between the two containers across the thread - which remains even when the containers are separated! </p> <p>Typically, the diameter of this bridge is no more than 1-3 mm, but can remain intact as far as an 25mm! The surface temperature, due to the voltage, rises from about <span> </span><span>20 °C</span><span> </span><span>(68 °F)</span><span> </span><span>up to</span><span> </span><span>60 °C</span><span>(140 °F)! The longest that the phenomenon has lasted is 45 minutes. </span></p> <p><span><a href="http://www.physorg.com/news110191847.html">Read more</a></span></p>http://unclegrandpapants.com/post/21395112045http://unclegrandpapants.com/post/21395112045Thu, 19 Apr 2012 22:38:31 +0200“Indeed, much of Newton’s intellectual development can be attributed to this tension between rationalism and mysticism. At the Stourbridge Fair in 1663, at age twenty, he purchased a book on astrology, ‘out of a curiosity to see what there was in it.’ He read it until he came to an illustration which he could not understand, because he was ignorant of trigonometry. So he purchased a book on trigonometry but soon found himself unable to follow the geometrical arguments. So he found a copy of Euclid’s ‘Elements of Geometry,’ and began to read. Two years later he invented the differential calculus.”<br/><br/> - <em><span>Carl Sagan, “Cosmos”</span> (via <a class="tumblr_blog" href="http://hirmes.tumblr.com/">hirmes</a>)</em>http://unclegrandpapants.com/post/21394942248http://unclegrandpapants.com/post/21394942248Thu, 19 Apr 2012 22:35:21 +0200<img src="http://25.media.tumblr.com/tumblr_m2i9134W6H1qz906xo1_500.jpg"/><br/><br/><p>by Daniel Selmeczi (<a class="tumblr_blog" href="http://bigfun.tumblr.com/post/21386243583/daniel-selmeczi-biosphoto">bigfun</a>)</p>http://unclegrandpapants.com/post/21394907825http://unclegrandpapants.com/post/21394907825Thu, 19 Apr 2012 22:34:42 +0200<img src="http://25.media.tumblr.com/tumblr_m2q7jh1Uwb1qz53glo1_500.png"/><br/><br/><p>The functions for the natural logarithm of a complex number (<a href="http://en.wikipedia.org/wiki/Complex_logarithm">wiki</a>)</p>http://unclegrandpapants.com/post/21377569351http://unclegrandpapants.com/post/21377569351Thu, 19 Apr 2012 14:18:52 +0200<img src="http://24.media.tumblr.com/tumblr_m1erlfockb1qe31lco1_r1_500.jpg"/><br/> <br/><img src="http://24.media.tumblr.com/tumblr_m1erlfockb1qe31lco2_500.jpg"/><br/> <br/><img src="http://25.media.tumblr.com/tumblr_m1erlfockb1qe31lco3_500.jpg"/><br/> <br/><img src="http://25.media.tumblr.com/tumblr_m1erlfockb1qe31lco4_500.jpg"/><br/> <br/><p>Would love to demonstrate <a href="http://en.wikipedia.org/wiki/Phonon">phonons</a> for a condensed matter physics class with this…</p> <p>(<a class="tumblr_blog" href="http://freshphotons.tumblr.com/post/20960245998/would-love-to-demonstrate-phonons-for-a-condensed">freshphotons</a>)</p>http://unclegrandpapants.com/post/20962214193http://unclegrandpapants.com/post/20962214193Thu, 12 Apr 2012 15:16:13 +0200<img src="http://25.media.tumblr.com/tumblr_lz3u4dfRfh1qas5xlo1_500.gif"/><br/><br/>http://unclegrandpapants.com/post/20903055092http://unclegrandpapants.com/post/20903055092Wed, 11 Apr 2012 16:05:40 +0200<object width="400" height="284"> <param name="movie" value="http://video.ted.com/assets/player/swf/EmbedPlayer.swf" /><param name="allowFullScreen" value="true" /><param name="allowScriptAccess" value="always" /><param name="wmode" value="transparent" /><param name="bgColor" value="#ffffff" /><param name="flashvars" value="vu=http://video.ted.com/talk/stream/2011/Blank/SheaHembrey_2011-320k.mp4&su=http://images.ted.com/images/ted/tedindex/embed-posters/SheaHembrey-2011.embed_thumbnail.jpg&vw=512&vh=288&ap=0&ti=1169&lang=&introDuration=15330&adDuration=4000&postAdDuration=830&adKeys=talk=shea_hembrey_how_i_became_100_artists;year=2011;theme=art_unusual;theme=tales_of_invention;theme=the_creative_spark;theme=what_makes_us_happy;event=TED2011;tag=art;tag=arts;tag=creativity;tag=design;tag=storytelling;&preAdTag=tconf.ted/embed;tile=1;sz=512x288;" /><embed src="http://video.ted.com/assets/player/swf/EmbedPlayer.swf" pluginspace="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" wmode="transparent" bgcolor="#ffffff" width="400" height="284" allowfullscreen="true" allowscriptaccess="always" flashvars="vu=http://video.ted.com/talk/stream/2011/Blank/SheaHembrey_2011-320k.mp4&su=http://images.ted.com/images/ted/tedindex/embed-posters/SheaHembrey-2011.embed_thumbnail.jpg&vw=512&vh=288&ap=0&ti=1169&lang=&introDuration=15330&adDuration=4000&postAdDuration=830&adKeys=talk=shea_hembrey_how_i_became_100_artists;year=2011;theme=art_unusual;theme=tales_of_invention;theme=the_creative_spark;theme=what_makes_us_happy;event=TED2011;tag=art;tag=arts;tag=creativity;tag=design;tag=storytelling;&preAdTag=tconf.ted/embed;tile=1;sz=512x288;"></embed></object> <br/><br/><p>Shea Hembrey: How I became 100 artists</p> <p>This is great.
