NOTE: This is sometimes mistakenly called “Curry’s Paradox,” because it was originated by a New York magician named Paul Curry. The actual Curry’s Paradox is a paradox in logic named for Haskell Curry.
An 82-foot telescope boasting ten times the resolution of the Hubble Space Telescope has successfully passed design reviews and is ready to be constructed.
The Giant Magellan Telescope will use a light-collecting mirror surface more than six times the area of current instruments to hunt for distant, potentially habitable planets and let astronomers time travel back to a billion years after the Big Bang.
A beautifully animated description of what we know about the creation of the Universe, so far. We can see most of the how, though who knows how long this can last. Does the universe build in enough time for the beings that study it, to reveal why it happened? We’ll see I guess. :D
With many satellites, people, and unused space debris orbiting Earth, the need to track this space debris in order to prevent disastrous collisions is growing. To solve this problem, a concept called Space-Based Telescopes for Actionable Refinement of Ephemeris (STARE) was developed at the Lawrence Livermore National Lab. It proposes the use of a network of nano satellites to track space debris by imaging possible collision candidates. The moving objects will then be mapped in relation to the stars and other debris in order to better predict their orbits.
Oxides form on the surfaces of metals because in the atmosphere they are in contact with oxygen. The nature of these oxides affect how we think of the metals themselves. For example everyone knows that if you leave iron laying around, it will get rusty.
The oxide layer on aluminum is very thin and adheres to the aluminum, insulating it from air and protecting it from oxidizing further. This is why we think of aluminum as a material that doesn’t corrode. (By the way, this aluminum oxide is the same compound that many gems are made of.)
Dmitri Ivanovich Mendeleev (Russian: Дми́трий Ива́нович Менделе́ев, IPA: [ˈdmʲitrʲɪj ɪˈvanəvʲɪt͡ɕ mʲɪndʲɪˈlʲejɪf] ; 8 February 1834 – 2 February 1907 O.S. 27 January 1834 – 20 January 1907) was a Russian chemist and inventor. He formulated the Periodic Law, created his own version of the periodic table
Insatiable Force Although their name suggests emptiness, black holes are the most densely filled objects in the universe, giving them enormous gravitational pull. Stellar black holes, formed from the collapse of giant stars, can compact the mass of ten suns to the size of New York City. Supermassive black holes at the center of galaxies can have the mass of billions of suns. Their origin remains a mystery.
Pancake day tomorrow - to mark the occasion, here’s a look at the major acidic compounds found in lemons. Also, why limes are a rubbish substitute when it comes to preventing scurvy… http://wp.me/p4aPLT-6U
