10 Strange Things About The Universe. Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ? 273.15°C, where the motion of all particles stops completely.
However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below. One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble. Relativity of Simultaneity Antimatter Retrocausality.
Incredible Space Pics from ISS by NASA astronaut Wheelock. Go Discovery! It was October 23, 2007 at 11:40am EST when I had my first ride to space on Discovery. She’s beautiful… just sad that this will be her last voyage. Looking forward to climbing aboard the flight deck when Discovery arrives at the Space Station in November. (9-23-2010). Incredible Photos from Space: Larry Tanner, NASA. Special thanks: Bethbeck’s blog On September 22, 2010, with the departure of the Expedition 23 crew, Colonel Douglas H.
We thought that we should put some of the space photos together as a tribute to him and the whole ISS crew. The following space photos are all visible on Astro_Wheels’ twitpic account, and we are eternally grateful to him for sharing these space photos with the world. Incredible Photos from Space: ‘Earthshine’… The Space Station basking in blue Earthshine as the rising sun pierces our razor-thin atmosphere to cover the Space Station with blue light.
NASA astronaut Douglas H. Kill Math. Bret Victor / April 11, 2011 The power to understand and predict the quantities of the world should not be restricted to those with a freakish knack for manipulating abstract symbols. When most people speak of Math, what they have in mind is more its mechanism than its essence. This "Math" consists of assigning meaning to a set of symbols, blindly shuffling around these symbols according to arcane rules, and then interpreting a meaning from the shuffled result. The process is not unlike casting lots. This mechanism of math evolved for a reason: it was the most efficient means of modeling quantitative systems given the constraints of pencil and paper. We are no longer constrained by pencil and paper. Project Kill Math is my umbrella project for techniques that enable people to model and solve meaningful problems of quantity using concrete representations and intuition-guided exploration.
Someday there will be an introductory essay on this page, and it will move you to tears. Kitchen Math. Richard P. Feynman Quotes. The Vega Science Trust - Richard Feynman - Science Videos. Chosen by the New Scientist - best on-line videos 2007. A set of four priceless archival science video recordings from the University of Auckland (New Zealand) of the outstanding Nobel prize-winning physicist Richard Feynman - arguably the greatest science lecturer ever. Although the recording is of modest technical quality the exceptional personal style and unique delivery shine through. Feynman gives us not just a lesson in basic physics but also a deep insight into the scientific mind of a 20th century genius analyzing the approach of the 17th century genius Newton. For the young scientist, brought up in this age of hi-tech PC/Power Point-based presentations, we also get an object lesson in how to give a lecture with nothing other than a piece of chalk and a blackboard.
Furthermore we are shown how to respond with wit and panache to the technical mishaps that are part-and-parcel of the lecturer`s life.

By Rob Waugh Updated: 17:48 GMT, 8 September 2011 Computer maker IBM has gone into partnership with a glue specialist to create 'skyscraper' computers - building huge sandwiches of silicon chips by sticking layer after layer of chips covered with tiny components together. It's hoped the process will create smartphones and PCs up to 1,000 times faster than today's - which may be on the market as early as 2013.
The company, 3M, also make heat resistant glues, adhesives used in the aerospace industry and sticky tape - but the hi-tech glues created in collaboration with IBM could actually be the key step towards making the next evolutionary leap in computing. IBM has teamed up with adhesive maker 3M to create hi-tech new chips that 'sandwich' up to 100 layers of silicon to create processors 1,000 times as powerful as today's Today's attempts at piling chips vertically - known as 3D packaging - face problems from overheating. The research aims to create 'stacks' of up to 100 layers of silicon. Scientists fooled by match box trick. Alcubierre Warp Drive Time Travel.
An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel. The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light" (although not in a local sense - see below). The key characteristics of the application of Alcubierre warp drives for time control and time travel are presented in the picture below.
This is followed by more detail describing the effect below. Alcubierre Warp Drive Description In 1994, the Mexican physicist Miguel Alcubierre proposed a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand.
