Yur coffee is not simply weak or unimpressive, the route to mediocrity taken by coffee served in sports bars, realty offices, hospital waiting rooms, and movie theaters.  No.  Yu push the envelope, yu develop a coffee that is AGGRESIVELY BAD.  Each time I drink it,  I literally have to brush my teeth before speaking with anyone (note: this is true). A deep, thorough brushing like arriving in prison or waking up in a storm drain.  &lt;/p&gt;

Warren’s &lt;i&gt;&lt;a href="http://en.wikipedia.org/wiki/All_the_king%27s_men"&gt;All the King’s Men&lt;/a&gt;&lt;/i&gt;, calls himself a ‘student of history’, believing that the present and the future are not simply products or consequences of the past, but are in fact the past transformed.  All of the past for Jack Burden therefore lives, its continuity never hidden but still unseen.&lt;br/&gt;&lt;br/&gt;&lt;a href="http://en.wikipedia.org/wiki/Stalin"&gt;Stalin,&lt;/a&gt; himself a student of history, maintained an obsessive grip on the present through the manipulation of the past.  Here, Stalin appears in a photo with and then without &lt;a href="http://en.wikipedia.org/wiki/Yezhov"&gt;Nikolai Yezhov&lt;/a&gt; (also known as ‘Blackberry’), the one time head of the &lt;a href="http://en.wikipedia.org/wiki/NKVD"&gt;NKVD&lt;/a&gt; and a &lt;a href="http://en.wikipedia.org/wiki/Cult_of_Personality_(song)"&gt;cult of personality&lt;/a&gt; during the &lt;a href="http://en.wikipedia.org/wiki/The_Great_Purge"&gt;Great Purge&lt;/a&gt;.  During Yezhov’s rule of the NKVD, he ruthlessly prosecuted its former head, &lt;a href="http://en.wikipedia.org/wiki/Genrikh_Yagoda"&gt;Yagoda,&lt;/a&gt; fabricating evidence against him and others which led to the execution of thousands of party officials.  Yezhov then himself fell by the same means, his power usurped, his own motives scrutinized and twisted until he crumbled, eventually confessing to crimes which warranted death.  Following his fall and execution, Yezhov was removed from Soviet history, not simply renounced but disappeared, leaving not a blemish but a vacuum.&lt;/p&gt;</description><link>http://jackjuly.tumblr.com/post/255107979</link><guid>http://jackjuly.tumblr.com/post/255107979</guid><pubDate>Mon, 23 Nov 2009 22:02:09 -0500</pubDate></item><item><title>Ån Anecdote: The Terrific Storm of the 12th of July Last:</title><description>&lt;p&gt;During the terrific storm of the 12&lt;sup&gt;th&lt;/sup&gt; of July last, a labourer’s cottage was struck by lightning at Leagrave, near here. The lightning descended, according to an eye-witness’s report, like a “spout of fire,” and struck and descended the chimney, which it destroyed. In the room below there was an old shepherd, an invalid woman, a child and a shepherd’s dog. The shepherd was sitting in a chair leaning on a stick, a kettle was boiling on the fire, and the door was open. The lightning entered the room simultaneously by the chimney and an adjoining window. The window was utterly destroyed, and the kettle was thrown from the fire across the room, the stick on which the shepherd was leaning was torn from his hand and also thrown across the room, the lightning entered a cupboard containing glass and crockery and destroyed every article, and plaster was torn from the walls. The man and woman remained unhurt, but the child was thrown down and its knees stiffened. The dog was struck perfectly stiff, “like a log of wood,” and was considered dead. The room seemed full of fire, water, and sulphur, and the occupants said the smell of sulphur was so strong that they would certainly have been suffocated had it not been for the open door. After the storm had abated, the dog, with all its limbs stiff, was laid in a barn, where it very slowly and partially recovered. It long remained both deaf and blind, and was entirely dependent upon smell for its recognition of persons and things.&lt;/p&gt;

&lt;p&gt;From the wikipedia page on &lt;a href="http://en.wikipedia.org/wiki/Abiogenesis"&gt;abiogenesis&lt;/a&gt;, the arisal of life on earth from inanimate matter.  At 4.5 billion years old, the Earth plenty of time to think things over before the animalcule &lt;a href="http://billydalto.tumblr.com/"&gt;party&lt;/a&gt; arrived.&lt;/p&gt;
&lt;p&gt;It has been shown that simulating the conditions of the early earth allows for the spontaneous synthesis of certain molecules necessary for life, though such spontaneous generation has not been demonstrated for other molecules (or for other planets). To prove the feasibility of biological self-assembly from non-biological precursors, several groups aim to synthesize entire proto-cells, hypothetical precursors to self-replicating bacteria, for example.  Some of the problems encountered involve the generation of lipids for membranes, the self-nucleation of enclosed vesicles to delineate a distinct internal chemical environment, and the passage of nucleic acids through membranes and into the protocellular space, where they can act as information storage molecules, or, as in the case of &lt;a href="http://en.wikipedia.org/wiki/Ribozyme"&gt;ribozymes&lt;/a&gt;, can catalyze chemical reactions.  Harvard’s Jack Szostak, who won the Nobel Prize today for unrelated work, leads this field and has some excellent simulations of nucleic acid passage and lipid growth &lt;a href="http://genetics.mgh.harvard.edu/szostakweb/movies.html"&gt;here&lt;/a&gt;.&lt;/p&gt;</description><link>http://jackjuly.tumblr.com/post/205349796</link><guid>http://jackjuly.tumblr.com/post/205349796</guid><pubDate>Mon, 05 Oct 2009 18:08:38 -0400</pubDate></item><item><title>noosphere:

Visualizing this destruction—and the efficacy of the drugs which execute it, has until now been nearly impossible.&lt;/p&gt;

Everyone in it is dead; their children’s children are dead and their memories are dead.  The photograph is not dead, but it is not a memory.

We experience through sensory information—colored by other experiences, and encoded in an un-understandable cascade of electrochemical signaling.  Each time we view a memory, we do so from farther away, and some fidelity is lost.  Memories are infinitely reducible and labile.  Finding an unremembered memory can evoke a painful emotional response, perhaps by virtue of its still native perfection against the experience it represents.

Photographs have the quality of being unchanging, though our experience of them may change.  They provide us with the starting materials for a new memory as much as they modify the memories we already own.  Memories alone are destroyed and rebuilt, but photographs become stakes to which our memory is forever tethered, a position to which the rebuilding of memory is constantly drawn.  In this way photographs not only eclipse and obscure elements of experience; they give to us the starting materials from which to build memories not experienced. &lt;/p&gt;</description><link>http://jackjuly.tumblr.com/post/139862780</link><guid>http://jackjuly.tumblr.com/post/139862780</guid><pubDate>Sat, 11 Jul 2009 20:00:53 -0400</pubDate></item><item><title>The vast majority of Henrietta Lacks was dead by the Fall of...</title><description>&lt;img src="http://5.media.tumblr.com/SyaaTlRHApmfyx4cCNDBp5Tno1_500.jpg"/&gt;&lt;br/&gt;&lt;br/&gt;&lt;p&gt;The vast majority of &lt;a href="http://en.wikipedia.org/wiki/Henrietta_Lacks"&gt;Henrietta Lacks&lt;/a&gt; was dead by the Fall of 1951, buried without a tombstone in Halifax County.  Only 9 months earlier, she had been diagnosed with cervical cancer.&lt;/p&gt;
&lt;p&gt;Cells from her cervical tumor were isolated, grown, and distributed.  Due to the ability of some cancer cells to grow and divide without regard for their environment, these immortal cells quickly became a bottomless source of research material (without her consent), and were sent all over the world, and even into space (to determine whether human cells can survive zero gravity).  The cells continue to divide today (above, via electron microscopy), in tens of thousands of laboratory incubators, and in such number that I wonder whether their mass now exceeds that of Lacks.&lt;/p&gt;</description><link>http://jackjuly.tumblr.com/post/137187404</link><guid>http://jackjuly.tumblr.com/post/137187404</guid><pubDate>Tue, 07 Jul 2009 13:30:37 -0400</pubDate></item></channel></rss>
