Two teams of astronomers observing the aftermaths of supernova explosions have announced findings that add fresh fuel to a dusty debate.
Supernovas have long been believed to be the universe’s prime “dust factories,” cataclysmic star deaths that spewed forth the stardust from which subsequent generations of stars, planets, and people were eventually formed.

Not only has a large chunk of the universe thought to have been found in 2002 apparently gone missing again but it is taking some friends with it, according to new research at The University of Alabama in Huntsville (UAH). The new calculations might leave the mass of the universe as much as ten to 20 percent lighter than previously calculated.

Imagine that a physicist detonates a nuclear bomb beside himself. In almost all parallel universes, the nuclear explosion will vaporize the physicist. However, there should be a small set of alternative universes in which the physicist somehow survives (i.e. the set of universes which support a “miraculous” survival scenario). The idea behind quantum immortality is that the physicist will remain alive in, and thus remain able to experience, at least one of the universes in this set, even though these universes form a tiny subset of all possible universes. Over time the physicist would therefore never perceive his or her own death.
Any questions?
OS/2 was a better OS than anything to date, but then again there were issues.
“Synchronous input queue (SIQ): if a GUI application was not servicing its window messages, the entire GUI system could get stuck and a reboot was required. This problem was considerably reduced with later Warp 3 fixpacks and refined by Warp 4, by taking control over the application after it had not responded for several seconds.”
The S.S. Brasil built in the late 1950’s was a spectacular ship (Photo 1). It sailed from the east coast of South America to New York and back for 14 years. In August 1972, she was sold to the Holland America Lines and became the “Volendam”. Later she was sold and renamed “Monarch Sun” three years later. Then in 1978, Holland America noticed that Monarch Cruise Lines was making too much money with the “Monarch Sun”, so it purchased Monarch Cruise Lines and renamed her “Volendam”. Over the next few years, she was sold and resold, named and renamed, flying many different flags: “Island Sun”, “Liberte”, “Canada Star”, “Queen of Bermuda” and ”Enchanted Seas”. Finally, as “Universe Explorer”, she became a charter to the Institute of Shipboard Education in association with the University of Pittsburgh.
On December 7, 2004, she was beached and disemboweled in Alang, India (the graveyard of many great ocean liners). (Photos 2 & 3)
I traveled on the S.S. Brasil as a child in the fall of 1959 from Santos to New York. It was the best of many ocean liners that I have traveled on (including the Italian Line’s majestic “Raffaello” and Cunard Line’s “Queen Mary”).
May she rest in peace.
An example is the bifurcation diagram of the logistic map:
The bifurcation parameter r is shown on the horizontal axis of the plot and the vertical axis shows the possible long-term population values of the logistic function.
Smile? I think not…
“In spite of outwardly unpretentious size of cat nose the organ of smell inside its’ head occupies pretty much space. Nostrils lengthen as nasal ducts and cavities, with perceptive cells in back sections that on the whole form the olfactory area of nose. Lattice “shells” situated here form a complex nasal labyrinth through which air filled with odors comes to perceptive cells. During the process of smelling cat actively draws the air in and provide a direct connect between perceptive cells and molecules of odorous substance. Perceptive cells are a region of brain bulged out on a nose surface. The cells are directly connected to olfactory centers. The connection occurs through internal endings of perceptive cells that are united in thin threads of fibers and penetrate through holes in lattice bones. Here, in brain cavity the olfactory lobe receives them and sends a thick bunch - olfactory tract - “convolutions of hippocampus” - to different sections of brain. The olfactory centers of cat include up to 67 millions of cells, 1,5 millions more then in human. A part of olfactory region of nose is stands apart as a Jacobson organ/ sometimes called voter-nasal by its’ location near the base of mouth. It consists of two symmetrical tubes that lengthen along the palate into Steenson ducts. Small apertures behind front teeth connect this organ with environment. A cat draws the air in the apertures, at that it stops rooted to the ground, opens its mouth and draws the lips in, wrinkling the skin on its’ head in a kind of grimace (Flemen’s smile). ”
