The magnitude of the energy of cosmic ray flux in interstellar space is very comparable to that of other deep space energies: cosmic ray energy density averages about one electron-volt per cubic centimetre of interstellar space, or ≈1 eV/cm 3, which is comparable to the energy density of visible starlight at 0.3 eV/cm 3, the galactic magnetic ...

Adam Ondra on the sport climbing route Silence, the hardest free climbing route in the world and the first-ever at 9c (French), 5.15d (American YDS), and XII+ (UIAA).. The two main free climbing grading systems (which include the two main free climbing disciplines of sport climbing and traditional climbing) are the "French numerical system" and the "American YDS system".

The purchase of the three aircraft included 12 spare GR2600A2A engines at a cost of $16,753 each and $21,750 for 19 Hamilton propellers. [44] The aircraft were to be operated by the British Overseas Airways Corporation (BOAC) and were primarily intended for the UK–West Africa route, as existing flying boats could not travel this route without ...
Seawater, or sea water, is water from a sea or ocean.On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na +
At T+81.7 seconds, a piece of foam approximately 21 to 27 inches (53 to 69 cm) long and 12 to 18 inches (30 to 46 cm) wide broke off from the left bipod on the ET. At T+81.9 seconds, the foam struck the reinforced carbon–carbon (RCC) panels on Columbia ' s left wing at relative velocity of 625 to 840 feet per second (426 to 573 mph; 686 to ...
Fast Times at Ridgemont High is a 1982 American coming-of-age comedy film directed by Amy Heckerling (in her feature directorial debut) from a screenplay by Cameron Crowe, based on his 1981 book Fast Times at Ridgemont High: A True Story, and starring Sean Penn, Jennifer Jason Leigh, Judge Reinhold, Phoebe Cates, Brian Backer, Robert Romanus, and Ray Walston.
The Moon is Earth's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
