This letter points out that the values of 'criticalacceleration' of MOND, and the 'accelerated-expansion' of the universe are just two of the fourteen strikingly equal values of accelerations recurring in different physical situations. Some of them could be explained by a new law of equality of potential-energy and energy-of-mass of reasonably-independent systems (Tank in Astrophys. Space Sci. 330:203-205, 2010; Tank in Adv. Stud. Theor. Phys. 5:45-55, 2011). This new conservation-law, of equality of potential-energy, energy-of-mass and 'kinetic-energy' may be a clue to understand MOND, and the 'accelerated-expansion' of the universe. Alternative expressions for the cosmological red-shift, the 'critical-acceleration' of MOND and Newton's law of universal gravitation are also presented for comparison of three different accelerations. © 2011 Springer Science+Business Media B.V.

The observation of 'cosmological-red-shift' is currently interpreted in terms of 'metric-expansion-of-space'; and it is believed that the universe is expanding; whereas here I first present some alternative-arguments and propose a new view-point, that: what expands is just the spherical-wave-front of light, not the universe. We visualize here a 'photon' as a pulse of very-small width, which occupies a small fraction of the spherical-shell of the wave-front of light. This can be imagined as a small dot marked on slightly-inflated-balloon; and the spherically-expanding-wave-front of light can be imagined as an ever-expandingballoon. So, with the expansion of the balloon, the size of the marked-dot, representing the 'photon', also gets increased. This process, when Fouriertransformed into the wave-number-domain, shows that with the increase of width of the pulse, called 'photon', its spectrum in the wave-number-domain shrinks towards zero-wave-number, which is currently believed to be 'the cosmologicalred- shift'. And the comparison of cosmological-red-shift with the strengths of gravitational and electric forces, done here, suggests that this new interpretation of the 'cosmological-red-shift', in terms of 'propagation-property of light', can be useful for the unification of gravitational and electric forces; for which Einstein struggled for the last forty years of his life. © 2013 Hasmukh K.

This author has recently reported [11] a new law, of equality of 'potential-energy' and 'energy-of-mass' obeyed by reasonably-independent systems of matter, like: the electron, the pi-meson, the hadrons, the nucleus-of-atom, the globular-clusters, the spiral-galaxy, the clusters-of-galaxies and the universe; but it was an empirical-law so far. Now, this paper presents a wave-theoretical explanation for this newly-emerged law. In this process the large-number-coincidence [LNC] and the recurrences of critical-acceleration of MOND also get explained in terms of the wave-theory. This paper suggests that this new law of equality of potential-energy and energy-of-mass may be more fundamental than the fundamental-forces, because it seems to determine the strengths of fundamental-forces.

India's Polar Satellite Launch Vehicle (PSLV) C-12 blasts off from Satish Dhawan space centre at Sriharikota, about 100 km (62 miles) north of the southern Indian city of Chennai, April 20, 2009. REUTERS/Babu More CAPE CANAVERAL, Fla. (Reuters) - A Colorado-based startup developing a satellite network to predict weather using radio signals will launch its first two spacecraft on an Indian rocket, the company said on Thursday. Privately owned PlanetiQ signed a contract with Antrix Corp Limited, the commercial arm of the Indian Space Research Organization, to launch the pair of satellites in late 2016. Terms of the contract were not disclosed. PlanetiQ plans to build and operate a constellation of 12 miniature satellites that monitor GPS and other navigational radio signals passing through Earth’s atmosphere. The signals change as they travel through different temperatures, pressures and levels of humidity, and the data can be incorporated into computer programs that predict local and regional weather and monitor changes in the global climate. PlanetiQ is among a handful of companies looking to exploit a growing demand for weather data for commercial and government use. With the 12 satellites in orbit, PlanetiQ expects to measure the atmosphere about 34,000 times a day worldwide at altitudes between 650 feet (200 meters) above ground all the way into the ionosphere. In  2013, agrochemical company Monsanto paid nearly $1 billion for the Climate Corporation, which produces apps of field-level weather, soil and crop data. Planet iQ's satellites will be positioned about 497 miles (800 km) above the planet and inclined about 98 degrees relative north and south of the equator. From that vantage point, PlanetiQ satellites will track radio signals from the U.S. Global Positioning System, Russia’s Glasnoss, China’s BeiDou and Europe’s Galileo satellites as they pass through the atmosphere. “The data is similar to that collected by weather balloons, but more accurate, more frequent and on a global scale,” PlanetiQ said. The remaining 10 satellites are expected to fly in 2017. “We are considering all secondary launch opportunities, though (we) are looking at only polar orbits now with higher altitudes preferred,” PlanetiQ Chief Executive Chris McCormick wrote in an email to Reuters. GeoOptics and Spire are two other startups planning to build and operate fleets of low-orbiting satellites equipped with so-called GPS radio occultation sensors. Tempus Global Data and HySpecIQ intend to fly a different type technology, called hyperspectral imaging, to collect similar atmospheric data.

This story incorrectly described the effect that Intel's Numonyx joint partnership with STMicroelectronics will have on its financial statements. Only the assets will vanish with the deal; Intel is still responsible for reporting any profit or loss made by Numonyx on its income statement in accordance with its stake.
