Sorry for any confusion I may have added to the thread.
Abstract Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? What properties of the material affect the way it vibrates? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs. Objective The goal of this project is to measure the vibrational frequency of spring/mass combinations using springs of different stiffness and a graded range of masses for each spring.
These observations show that our Sun is moving through a Local Interstellar Cloud as this cloud flows outwards from the Scorpius-Centaurus Association star forming region. Our Sun may exit the Local Interstellar Cloud during the next 10,000 years. Much remains unknown about the local ISM, including details of its distribution, its origin, and how it affects the Sun and the Earth.
Our solar system may be headed for an encounter with a dense cloud of interstellar matter–gas and dust–that could have substantial implications for our solar system’s interplanetary environment, according to University of Chicago astrophysicist Priscilla Frisch. The good news is that it probably won’t happen for 50,000 years. Frisch presented the results of her research Monday, June 10, at the meeting of the American Astronomical Society in Madison, Wisc. Frisch has been investigating the interstellar gas in the local neighborhood of our solar system, which is called the Local Interstellar Medium (LISM). This interstellar gas is within 100 light years of the Sun. The Sun has a trajectory through space, and for most of the last five million years, said Frisch, it has been moving through a region of space between the spiral arms of the Milky Way galaxy that is almost devoid of matter. Only recently, within the last few thousand years, she estimates, the Sun has been traveling through a relatively low-density interstellar cloud. “This cloud, although low density on average, has a tremendous amount of structure to it,” Frisch said. “And it is not inconsistent with our data that the Sun may eventually encounter a portion of the cloud that is a million times denser than what we’re in now.”
Accelerometers can measure: vibrations, shocks, tilt, impacts and motion of an object.
It is known that collisionless shocks are associated with extremely high energy particles, although it has not been definitively established if the high energy photons observed are emitted by protons, electrons or both. The energetic particles are in general believed to be accelerated by the Fermi acceleration mechanism. It is usually agreed that shocks caused by supernova remnants expanding in the interstellar medium accelerate the cosmic rays measured above the Earth's atmosphere.
n that case, what could be causing this humming in the sky?In our opinion, the source of such powerful and immense manifestation of acoustic-gravity waves must be very large-scale energy processes. These processes include powerful solar flares and huge energy flows generated by them, rushing towards Earth’s surface and destabilizing the magnetosphere, ionosphere and upper atmosphere. Thus, the effects of powerful solar flares: the impact of shock waves in the solar wind, streams of corpuscles and bursts of electromagnetic radiation are the main causes of generation of acoustic-gravitation waves following increased solar activity.Given the surge in solar activity as manifested itself in the higher number and energy of solar flares since mid-2011, we can assume that there is a high probability of impact of the substantial increase in solar activity on the generation of the unusual humming coming from the sky.
But you said that the cause of the “sky hum” can lie within Earth’s core as well, what does it mean?There is one more possible cause of these sounds and it may lie at the Earth’s core. The fact is that the acceleration of the drift of the Earth’s north magnetic pole which increased more than fivefold between 1998 and 2003 and is at the same level today points to intensification of energy processes in the Earth’s core, since it is processes in the inner and outer core that form the Earth’s geomagnetic field. Meanwhile, as we have already reported, on November 15, 2011 all ATROPATENA geophysical stations which record three-dimensional variations of the Earth’s gravitational field almost simultaneously registered a powerful gravitational impulse. The stations are deployed in Istanbul, Kiev, Baku, Islamabad and Yogyakarta, with the first and last one being separated by a distance of about 10,000 km. Such a phenomenon is only possible if the source of this emanation is at the Earth’s core level. That huge energy release from the Earth’s core at the end of the last year was some kind of a start signal indicating the transition of the Earth’s internal energy into a new active phase.
1998 saw the beginning of abnormal changes in some of Earth’s geophysical parameters, a leap in J2 coefficient values in particular. This coefficient is determined using measurements made by the laser ranging system from US satellites. The J2 coefficient demonstrates the dynamics of the ratio between Earth’s equatorial and polar radii. According to NASA, the J2 coefficient had been decreasing for many years supposedly due to the release of meltwater from the mantle since the ice age. This was indicative of an increase in Earth’s radius at the poles and its reduction at the equator. Meanwhile, new data show that since 1998 the J2 coefficient began to grow. This process reflects the global redistribution of Earth’s masses, as well as Earth’s expansion at the equator and its flattening at the poles. Thus, some global-scale event is thought to have occurred in 1998; this could mean both global redistribution of Earth’ masses and minor changes of its shape.
SECTION 3 Cosmic-Terrestrial Relations, Chronobiology, BIOCOS Program META-ANALYTIC HISTORY OF CONGRUENT CYCLES IN SPACE WEATHER, THE HUMAN MIND AND OTHER AFFAIRS Franz Halberg, Germaine Cornélissen, Francine Halberg, Patricia Grambsch, Othild Schwartzkopff Halberg Chronobiology Center, University of Minnesota, Minneapolis, MN, USA We need tools for understanding, predictions, alerts and the rational design of countermeasures of societal cataclysms, such as terrorism and war, and of natural disasters such as earthquakes, and may find these tools in data collected to avoid personal cataclysms such as massive strokes; in the same data, antecedents of the cataclysms, in the form of time structure alterations not found in various controls, may be sought. Concurrent controls can be complemented, when possible, e.g., by prior data without an event, in similar cycle stages. Such investigations, superposed epochs from many earthquakes, andMonte Carlo methods could identify harbingers that, in their turn, could prompt the evasion of natural disasters and perhaps the avoidance of other man-made cataclysms. With historical data meta-analyzed herein, mapping the time structures of terrorist acts and of a host of environmental variables leads to putative triggers affecting the mind of populations, analyzable as cycles in individuals. Cycles in aggression and their periodic counterparts in our environment, far as well as near, currently (with notable exceptions) ignored in the West, have long been recognized in importance in Russia and its associated states. Yet in England, already in 1801, Sir William Herschel had raised concerns about the consequences in human and other earthly affairs, including crops, of an "ill-disposed" sun. Apart from the foregoing reasons, basic science needs to monitor not only the weather on earth and in extraterrestrial space, but also the consequences of space weather in populations and individuals. The mechanism involved can be studied at the cost of computer-aided self-surveillance for avoiding a stroke.
HUNGRY parents in North Korea have been caught eating their CHILDREN to avoid starvation, according to reports. One father is said to have been executed by firing squad for killing his two kids for food. And it has sparked fears there could be further cases of cannibalism in the country. The Sunday Times told how undercover reporters recorded several horror stories from inside the poverty-stricken nation. They included one man who dug up his grandchild's corpse to eat and another who boiled his child and ate the flesh. Thousands of North Koreans are feared to be starving to death while their chubby leader Kim Jong-Un regularly dines on banquets. It is claimed that more than 10,000 people could have died from in the provinces south of the capital Pyongyang alone. One informant in South Hwanghae, said: "In my village in May a man who killed his own two children and tried to eat them was executed by a firing squad." Read more: www.thesun.co.uk...
