This vertical view shows the complex caldera at the summit of Olympus Mons on Mars, the highest volcano in our Solar System. Olympus Mons has an average elevation of 22 km and the caldera has a depth of about 3 km This is the first high-resolution colour image of the complete caldera of Olympus Mons. The colour image was taken from a height of 273 km in orbit 37 by the High

Highlights of the Year 20 December 2002 2002 has been an exciting year for physicists. From the production of large numbers of anti-atoms at cern to the first measurement of the polarization of the cosmic background radiation, there

SPIRIT UPDATE: Spirit probes deeper into 'Clovis'outcrop-sol 209-218, August 23,2004 Spirit continued work over the past nine sols at a rock called \Clovis.\ The rover used roscop its rock abrasion tool, microscopic imager, alpha particle X-ray- spectrometer,and Mossbauer spectrometer to probe deeper into the history of this rock. Clovis is the most altered rock encountered by Spirit to date. It is part of a rock outcrop located on the\West Spur\ of the \Columbia

据新华网援引《国际先驱导报》报道,英国《卫报》等媒体日前报道,著名物理学家、英 国剑桥大学教授斯蒂芬·霍金宣布他已放弃对“万有理论”( theory of everything)的追求,过 去他认为人们很快就能找到一个至少能在原则上描述、预测宇宙中所有事物的终极“万有理 论”,而现在他认为,人们永远都获得不了这样的理论:因为根据数学中的哥德尔不完备性 定理,这样的理论根本就不可能有 T恤衫上的终极理论

Winds provide the energy to set the 1940 Tacoma Narrows Bridge motion Oscillations travel to the central span and reflected from support towers. By the principle of superposition the primary and reflected waves turn into a standing torsional wave

The models of specific heat based on equipartition of energy and including rotational degrees of freedom as well as translational are able to explain specific heats for diatomic molecules. The departure from this model in the case of polyatomic molecules indicates vibrational involvement
