Planck Time
What is the smallest unit of time you can conceive? A second? A millisecond? Hard to say seeing as how time is relative. Under the right circumstances, hours can fly by and seconds can feel like a lifetime. But unfortunately for physicists, time is not something that can be delt with so philosophically. And since they deal with cosmological forces both infinitesimally large and small, they need units that can objectively measure them. When it comes to dealing with the small, Planck Time is the measurement of choice. Named after German physicist Max Planck, the founder of quantum theory, a unit of Planck time is the time it takes for light to travel, in a vacuum, a single unit of Planck length. Taken together, they part of the larger system of natural units known as Planck units.
Originally proposed in 1899 by German physicist Max Planck, Planck units are physical units of measurement defined exclusively in terms of five universal physical constants. These are the Gravitational constant (G), the Reduced Planck constant (h), the speed of light in a vacuum (c), the Coulomb constant(ke or k), and Boltzmann’s constant (kB, sometimes k). Each of these constants can be associated with at least one fundamental physical theory: c with special relativity, G with general relativity and Newtonian gravity, with quantum mechanics, with electrostatics, and kB with statistical mechanics and thermodynamics. They were invented as a means of simplifying the particular algebraic expressions appearing in theoretical physics, especially in quantum mechanics.
Ultimately, Planck time is derived from the field of mathematical physics known as dimensional analysis, which studies units of measurement and physical constants. The Planck time is the unique combination of the gravitational constant G, the relativity constant c, and the quantum constant h, to produce a constant with units of time. They are often semi-humorously referred to by physicists as “God’s units” because eliminate anthropocentric arbitrariness from the system of units, unlike the meter and second, which exist for purely historical reasons and are not derived from nature. Some challenges to Planck’s Time have been mounted. For example, in 2003 during the analysis of the Hubble Space Telescope Deep Field images, some scientists speculated that where there are space-time fluctuations on the Planck scale, images of extremely distant objects should be blurry. The Hubble images, they claimed, were too sharp for this to be the case. Other scientists disagreed with this assumption however, with some saying the fluctuations would be too small to be observable, others saying that the speculated blurring effect that was expected was off by a very large magnitude. A unit of Planck Time can be expressed (in the third picture).

Israel & Mexico swap notes on abusing rights
May 22, 2013Earlier this month, Jorge Luis Llaven Abarca, Mexico’s newly-appointed secretary of public security in Chiapas, announced that discussions had taken place between his office and the Israeli defense ministry. The two countries talked about security coordination at the level of police, prisons and effective use of technology (“Israeli military will train Chiapas police,” Excelsior, 8 May [Spanish]).
Chiapas is home to the Zapatistas (Ejército Zapatista de Liberación Nacional), a mostly indigenous Maya liberation movement that has enjoyed global grassroots support since it rose up against the Mexican government in 1994. The Zapatistas took back large tracts of land on which they have since built subsistence cooperatives, autonomous schools, collectivized clinics and other democratic community structures.
In the twenty years since the uprising, the Mexican government has not ceased its counterinsurgency programs in Chiapas. When Llaven Abarca was announced as security head in December, human rights organizations voiced concerns that the violence would escalate, pointing to his history of arbitrary detentions, use of public force, criminal preventive detentions, death threats and torture (“Concern about the appointment of Jorge Luis Llaven Abarca as Secretary of Public Security in Chiapas,” Fray Bartolomé de Las Casas (Frayba) Center for Human Rights,14 December 2012 [PDF, Spanish]).
Aptly, his recent contacts with Israeli personnel were “aimed at sharing experiences,” Abarca has claimed. This may be the first time the Mexican government has gone public about military coordination with Israelis in Chiapas. Yet the agreement is only the latest in Israel’s longer history of military exports to the region, an industry spawned from experiences in the conquest and pacification of Palestine.
Weapons sales escalate
The first Zionist militias (Bar Giora and HaShomer) were formed to advance the settlement of Palestinian land. Another Zionist militia, the Haganah — the precursor to the Israeli army and the successor of HaShomer — began importing and producing arms in 1920.
Israeli firms began exporting weapons in the 1950s to Latin America, including to Nicaragua and the Dominican Republic under the Somoza and Trujillo dictatorships. Massive government investment in the arms industry followed the 1967 War and the ensuing French arms embargo. Israeli arms, police, military training and equipment have now been sent to at least 140 countries, including to Guatemala in the 1980s under Efraín Ríos Montt, the former dictator recently convicted of genocide against the Maya.
Mexico began receiving Israeli weaponry in 1973 with the sale of five Arava planes fromIsrael Aerospace Industries. Throughout the 1970s and ’80s, infrequent exports continued to the country in the form of small arms, mortars and electronic fences. Sales escalated in the early 2000s, according to research that we have undertaken.
In 2003, Mexico bought helicopters formerly belonging to the Israeli army and Israel Aerospace Industries’ Gabriel missiles. Another Israeli security firm, Magal Security Systems, received one of several contracts for surveillance systems “to protect sensitive installations in Mexico” that same year, The Jerusalem Post reported.
In 2004, Israel Shipyards sold missile boats, and later both Aeronautics Defense Systems and Elbit Systems won contracts from the federal police and armed forces for drones for border and domestic surveillance (“UAV maker Aeronautics to supply Mexican police,”Globes, 15 February 2009). Verint Systems, a technology firm founded by former Israeli army personnel, has won several US-sponsored contracts since 2006 for the mass wiretapping of Mexican telecommunications, according to Jane’s Defence Weekly.
Trained by Israel
According to declassified Defense Intelligence Agency documents [PDF] obtained via a freedom of information request, Israeli personnel were discreetly sent into Chiapas in response to the 1994 Zapatista uprising for the purpose of “providing training to Mexican military and police forces.”
The Mexican government also made use of the Arava aircraft to deploy its Airborne Special Forces Group (Grupo Aeromóvil de Fuerzas Especiales, or GAFE). GAFE commandos were themselves trained by Israel and the US. Several would later desert the GAFE and go on to create “Los Zetas,” currently Mexico’s most powerful and violent drug cartel (“Los Zetas and Mexico’s Transnational Drug War,” World Politics Review, 25 December 2009).
Mexico was surprised by the Zapatistas, who rose up the day the North American Free Trade Agreement went into effect. The Mexican government found itself needing to respond to the dictates of foreign investors, as a famously-leaked Chase-Manhattan Bank memo revealed: “While Chiapas, in our opinion, does not pose a fundamental threat to Mexican political stability, it is perceived to be so by many in the investment community. The government will need to eliminate the Zapatistas to demonstrate their effective control of the national territory and of security policy.”
Un golpe más para la minoría indígena de el México contemporáneo triste es en verdad esta alianza con las fuerzas sionistas en contra del EZLN, un grupo que sólo desea el beneficio y seguridad de su gente subyugada.
