Navigating the Solar System Using Pulsars as GPS

GPS works by having orbiting atomic clocks beaming out the current time. GPS receivers pick up several signals, do some mathematical trickery, and determine their geographical location by correlating the relative differences and doing some triangulating. The general principle  would seem to work on a vastly larger scale by using the surprisingly precise signals from pulsars.

The Mexican volcano Popocatépetl went off a few days ago. A camera caught the eruption, including the shockwave going down the mountainside and blasting through the nearby clouds.

Long Exposure Photos of Gunfire at Night

In April of 1970 I was near Phu Tai, Vietnam in the 173rd Airborne Brigade Admin Compound. We were pissed off at taking Viet Cong sniper fire from the mountain above us several nights in a row. The guy would stand up from behind a rock and blow off a clip from his AK47 on full-auto. The sniper was shooting at such a high angle that most of his rounds came through the sheet metal roofs of our hooches. We decided to use a “heavy” response the next time(s) the sniper hit us.

Take a look at the photos at the link. No, really. Go look. Dayum.

An interesting article on the Civil War:

150 Years of Misunderstanding the Civil War

The Civil War was a more complex issue than many people like to suggest. It had a thousand causes, and caused a billion problems, and the high-mindedness of many of the claims fell flat in the face of post-war realities. But despite failings on all sides, there is one line of argument that I’ve found particularly offensive, due to the blatant historical dishonesty of it: “The war was not about slavery.” The problem here is that slavery was at the very heart of the matter. If slavery was not a point of contention, then the issues of taxation and tariffs and federal intrusion into states rights could have been dealt with.  And who better to ask “why was the war fought” than the Southern leadership of the time?

For example: on March 21, 1862, Vice President of the CSA, Alexander Stephens, gave the “Corner Stone Speech” in Savannah, Georgia. In a speech that included rhetoric about “the broad principle of perfect equality and justice,” he also included:

The new constitution has put at rest, forever, all the agitating questions relating to our peculiar institution African slavery as it exists amongst us the proper status of the negro in our form of civilization. This was the immediate cause of the late rupture and present revolution. Jefferson in his forecast, had anticipated this, as the “rock upon which the old Union would split.” He was right. What was conjecture with him, is now a realized fact. But whether he fully comprehended the great truth upon which that rock stood and stands, may be doubted. The prevailing ideas entertained by him and most of the leading statesmen at the time of the formation of the old constitution, were that the enslavement of the African was in violation of the laws of nature; that it was wrong in principle, socially, morally, and politically. It was an evil they knew not well how to deal with, but the general opinion of the men of that day was that, somehow or other in the order of Providence, the institution would be evanescent and pass away. This idea, though not incorporated in the constitution, was the prevailing idea at that time. The constitution, it is true, secured every essential guarantee to the institution while it should last, and hence no argument can be justly urged against the constitutional guarantees thus secured, because of the common sentiment of the day. Those ideas, however, were fundamentally wrong. They rested upon the assumption of the equality of races. This was an error. It was a sandy foundation, and the government built upon it fell when the “storm came and the wind blew.”

Our new government is founded upon exactly the opposite idea; its foundations are laid, its corner- stone rests, upon the great truth that the negro is not equal to the white man; that slavery subordination to the superior race is his natural and normal condition. This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth. This truth has been slow in the process of its development, like all other truths in the various departments of science. It has been so even amongst us. Many who hear me, perhaps, can recollect well, that this truth was not generally admitted, even within their day. The errors of the past generation still clung to many as late as twenty years ago. Those at the North, who still cling to these errors, with a zeal above knowledge, we justly denominate fanatics. All fanaticism springs from an aberration of the mind from a defect in reasoning. It is a species of insanity. One of the most striking characteristics of insanity, in many instances, is forming correct conclusions from fancied or erroneous premises; so with the anti-slavery fanatics. Their conclusions are right if their premises were. They assume that the negro is equal, and hence conclude that he is entitled to equal privileges and rights with the white man. If their premises were correct, their conclusions would be logical and just but their premise being wrong, their whole argument fails.

From the Declaration of the Immediate Causes Which Induce and Justify the Secession of South Carolina from the Federal Union

The people of the State of South Carolina, in Convention assembled, on the 26th day of April, A.D., 1852, declared that the frequent violations of the Constitution of the United States, by the Federal Government, and its encroachments upon the reserved rights of the States, fully justified this State in then withdrawing from the Federal Union; but in deference to the opinions and wishes of the other slaveholding States, she forbore at that time to exercise this right. Since that time, these encroachments have continued to increase, and further forbearance ceases to be a virtue.

And now the State of South Carolina having resumed her separate and equal place among nations, deems it due to herself, to the remaining United States of America, and to the nations of the world, that she should declare the immediate causes which have led to this act.

… And just what were these Constitutional violations by the FedGuv that so offended?

The Constitution of the United States, in its fourth Article, provides as follows: “No person held to service or labor in one State, under the laws thereof, escaping into another, shall, in consequence of any law or regulation therein, be discharged from such service or labor, but shall be delivered up, on claim of the party to whom such service or labor may be due.”

In short, they were P.O.ed that non-slaver states were refusing to return escaped slaves under the Fugitive Slave Act. One of the great ironies here is that “states rights” is often used to support the southern cause, yet it was “states rights” that caused non-slave states to ignore the Fugitive Slave Act and not ship escapees back. At the same time, apologists for the War of Southern Aggression like to yammer about”states rights,” yet the Fugitive Slave laws were intended to enforce the principles of slavery onto the non-slave states.  What about those states rights?

From the Georgia Declaration of Secession:

The people of Georgia having dissolved their political connection with the Government of the United States of America, present to their confederates and the world the causes which have led to the separation. For the last ten years we have had numerous and serious causes of complaint against our non-slave-holding confederate States with reference to the subject of African slavery. They have endeavored to weaken our security, to disturb our domestic peace and tranquility, and persistently refused to comply with their express constitutional obligations to us in reference to that property, and by the use of their power in the Federal Government have striven to deprive us of an equal enjoyment of the common Territories of the Republic. This hostile policy of our confederates has been pursued with every circumstance of aggravation which could arouse the passions and excite the hatred of our people, and has placed the two sections of the Union for many years past in the condition of virtual civil war. Our people, still attached to the Union from habit and national traditions, and averse to change, hoped that time, reason, and argument would bring, if not redress, at least exemption from further insults, injuries, and dangers. Recent events have fully dissipated all such hopes and demonstrated the necessity of separation. 

And it goes on like that for quite a while.

From A Declaration of the Immediate Causes which Induce and Justify the Secession of the State of Mississippi from the Federal Union

In the momentous step which our State has taken of dissolving its connection with the government of which we so long formed a part, it is but just that we should declare the prominent reasons which have induced our course.

Our position is thoroughly identified with the institution of slavery– the greatest material interest of the world. Its labor supplies the product which constitutes by far the largest and most important portions of commerce of the earth. These products are peculiar to the climate verging on the tropical regions, and by an imperious law of nature, none but the black race can bear exposure to the tropical sun. These products have become necessities of the world, and a blow at slavery is a blow at commerce and civilization. That blow has been long aimed at the institution, and was at the point of reaching its consummation. There was no choice left us but submission to the mandates of abolition, or a dissolution of the Union, whose principles had been subverted to work out our ruin.

From A Declaration of the Causes which Impel the State of Texas to Secede from the Federal Union

Texas abandoned her separate national existence and consented to become one of the Confederated Union to promote her welfare, insure domestic tranquility and secure more substantially the blessings of peace and liberty to her people. She was received into the confederacy with her own constitution, under the guarantee of the federal constitution and the compact of annexation, that she should enjoy these blessings. She was received as a commonwealth holding, maintaining and protecting the institution known as negro slavery– the servitude of the African to the white race within her limits– a relation that had existed from the first settlement of her wilderness by the white race, and which her people intended should exist in all future time. Her institutions and geographical position established the strongest ties between her and other slave-holding States of the confederacy. Those ties have been strengthened by association. But what has been the course of the government of the United States, and of the people and authorities of the non-slave-holding States, since our connection with them?

The controlling majority of the Federal Government, under various pretences and disguises, has so administered the same as to exclude the citizens of the Southern States, unless under odious and unconstitutional restrictions, from all the immense territory owned in common by all the States on the Pacific Ocean, for the avowed purpose of acquiring sufficient power in the common government to use it as a means of destroying the institutions of Texas and her sister slaveholding States.

By the disloyalty of the Northern States and their citizens and the imbecility of the Federal Government, infamous combinations of incendiaries and outlaws have been permitted in those States and the common territory of Kansas to trample upon the federal laws, to war upon the lives and property of Southern citizens in that territory, and finally, by violence and mob law, to usurp the possession of the same as exclusively the property of the Northern States.

In other words: boo hoo, they’re not letting us expand the institution of slavery into new territories.

Sure, economics and “states rights” were important points of contention, then as now. But slavery was the basis of the economics, and slavery was the source of the “states rights” issue.  And just how hypocritical do you have to be to go on about states rights, yet ignore the rights of the individual? Just as the states are supposed to be able to the FedGuv to go piss up a rope when it over-reaches, the individual can tell a state to get bent if it tries some jackassery.

The thing is, the south was on the wrong side of history, the wrong side of morality, the wrong side of the difference between an agrarian society and an industrial one, and the wrong side of tactics and strategy. They lost. Everyone today merrily waving the “Stars and Bars” is waving the flag of losers, and they’d know it if they honestly examined the facts. And yet, like creationists, flat Earthers, hard-core global warming deniers, gun control advocates, anti-nuke activists and the like, Confederate apologists have for the last century and a half proven to be immune from facts and reason. A seeming irrelevant article has come along that might help explain it:

The Science of Why We Don’t Believe Science

In other words, when we think we’re reasoning, we may instead be rationalizing. Or to use an analogy offered by University of Virginia psychologist Jonathan Haidt: We may think we’re being scientists, but we’re actually being lawyers (PDF). Our “reasoning” is a means to a predetermined end—winning our “case”—and is shot through with biases. They include “confirmation bias,” in which we give greater heed to evidence and arguments that bolster our beliefs, and “disconfirmation bias,” in which we expend disproportionate energy trying to debunk or refute views and arguments that we find uncongenial.

Back in the 1970’s, the “Army surplus store” was actually filled with Army surplus. Military outfits, helmets, bayonets, de-miled flamethrowers, de-miled rocket launchers, flak jackets, instruments, grenades, shells, bombs, guns, you name it. Back then the stores were loaded with surplus from Viet Nam, Korea and even WWII, along with the “peacetime” in between. But if you go into such a store today, you’re far more likely to find a store full of commercial camping supplies and the like. Now, it’s not as if the military hasn’t been buying, and then replacing, shiploads of *stuff,* but there seems to be vastly less of it making its way back to the US civvie market. For instance: when was the last time you saw a civilian owned M-1 Abrams, AH-64 Apache or F-14 Tomcat?

There is news relevant on that topic:

Scrapping equipment key to Afghan drawdown

the U.S. military has destroyed more than 170 million pounds worth of vehicles and other military equipment as it rushes to wind down its role in the Afghanistan war by the end of 2014.

About 2,000 MRAP (Mine-Resistant Ambush Protected) vehicles are listed as “excess” and are being shredded.

One would imagine that there are a vast number of AR-15/M-4/M-16 magazines that are kinda beat up, but that civilian gun owners woul snap up if the price was right. Not to mention the M-4’s, M-16’s, M-14’s, Barrets, sidearms and all the rest that would find many happy buyers back home.

A book excerpt from “The Skies Belong to Us: Love and Terror in the Golden Age of Hijacking” which looks to be a pretty interesting history of air travel in the late 1960’s/early 1970’s, when “this plane/bus/train is going to Cuba” became something of a recurring joke:

How Hijackers Commandeered Over 130 American Planes — In 5 Years

While the 1968-1972 period is a bit before my time, popular culture in the decade or so that followed remembered the burst of idiots who just had to go to Cuba and used it as a theme both dramatically and comically. But a question I’ve long not wondered about – because it never really occurred to me to care – was “what happened to those hijackers who made it to Cuba?” Well, after long and grueling interrogations by the Cuban police, the…

 lucky ones were then sent to live at the Casa de Transitos (Hijackers House), a decrepit dormitory in southern Havana, where each American was allocated sixteen square feet of living space; the two-story building eventually held as many as sixty hijackers, who were forced to subsist on monthly stipends of forty pesos each. Skyjackers who rubbed their G2 interrogators the wrong way, meanwhile, were dispatched to squalid sugar-harvesting camps, where conditions were rarely better than nightmarish. At these tropical gulags, inmates were punished with machete blows, political agitators were publicly executed, and captured escapees were dragged across razor-sharp stalks of sugarcane until their flesh was stripped away. One American hijacker was beaten so badly by prison guards that he lost an eye; another hanged himself in his cell.

Heh. Who woulda guessed it… idiots who thought Cuba was a socialist paradise find that, gee whiz, it actually kinda sucks…
