Earth Axis Tilt Experiment ) with some gravitational variation experiments to determine the rate at which the earth's polar axis is tilting. I have reason to believe that not only the north magnetic pole of Earth but also the axis of spin are beginning to undergo some dramatic changes. As you may have heard I am working on Part 2 of my gravitational research paper. As part of the research for that paper I devised some simple tests to monitor changes in the Earth's gravitational field between our northern and southern hemispheres.

Does the Earth's magnetic field cause suicides? Does the Earth's magnetic field cause suicides?______________________________________________ Many animals can sense the Earth's magnetic field, so why not people, asks Oleg Shumilov of the Institute of North Industrial Ecology Problems in Russia. Shumilov looked at activity in the Earth's geomagnetic field from 1948 to 1997 and found that it grouped into three seasonal peaks every year: one from March to May, another in July and the last in October.

Earth's magnetic field Computer simulation of the Earth's field in a period of normal polarity between reversals.[1] The lines represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and vertical. The dense clusters of lines are within the Earth's core.[2] Honshu earthquake tore gash in the Earth 150 miles long, 50 miles wide March 11, 2011 – JAPAN - A massive earthquake that struck off the coast of Japan Friday was the strongest quake in the area in nearly 1,200 years. David Applegate, a senior science adviser for earthquake and geologic hazards for the U.S. Geological Survey, said the 8.9-magnitude quake ruptured a patch of the earth’s crust 150 miles long and 50 miles across. He said the earthquake, which also spawned a massive tsunami that hit Japan before racing across the Pacific Ocean to Hawaii and the West Coast of the United States, likely caused tens of billions of dollars in structural damage in Japan. Laura K. Furgione, deputy director for the National Weather Service, said the tsunami first hit Hawaii early Friday morning.

Strategy & Innovation Department at Boston University School of Our mission is to provide thought leadership in the field of strategy in order to inform our peers, students, and, ultimately, the practitioners worldwide who must deal with the realities of a complex and fast-changing world. We focus broadly on how new and established firms generate and sustain performance differentials over their competitors. We are interested in exploring not just the appropriate strategy for conditions but how firms execute on that strategy and the practices that most effectively enable implementation. We place particular emphasis on the study of innovation in different kinds of organizations and the role of technological change in creating new industries and reshaping existing ones.

Transparency Index The Transparency Index is a way of comparing how well EU member states are doing at providing information on who gets what from the Common Agricultural Policy. The scores are out of 100 and are weighted averages based on a number of criteria including: the number of years for which data has been released; the amount of detail in the data, e.g. geographical location, description of subsidy schemes, date, currency etc; the format of disclosure (we give extra points for disclosure of raw data in a machine-readable format and we penalise disclosure in PDF files). They are calculated and regularly updated by Nils Mulvad, co-founder of Countries that release comprehensive and detailed data in a machine-readable format will score highly.

Ionosphere The ionosphere is a region of the upper atmosphere, from about 85 km (53 mi) to 600 km (370 mi) altitude, and includes the thermosphere and parts of the mesosphere and exosphere. It is distinguished because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth.[1] Relationship of the atmosphere and ionosphere Quake moved Japan coast 8 feet, shifted Earth's axis Images released by NASA show Japan's northeast coast before, left, and after flooding from the quake-induced tsunami. Friday's powerful earthquake appears to have moved the main island of Japan by 8 feet Report: The 8.9-magnitude earthquake shifted the Earth on its axis by 4 inchesThe quake triggered more than 160 aftershocks in the first 24 hours Similar strength to the 2004 quake and tsunami that killed more than 200,000 people (CNN) -- The powerful earthquake that unleashed a devastating tsunami Friday appears to have moved the main island of Japan by 8 feet (2.4 meters) and shifted the Earth on its axis.

Shift of Earth's Magnetic North Pole Impacts Tampa Airport © Tampa Bay OnlineRunway changes are needed to account for the moving magnetic pole, which is nearing Russia at 40 miles per year. Scientists say the magnetic north pole is moving toward Russia and the fallout has reached -- of all places -- Tampa International Airport. The airport has closed its primary runway until Jan. 13 to repaint the numeric designators at each end and change taxiway signage to account for the shift in location of the Earth's magnetic north.
