Session 40 - The Interstellar Medium.
Display session, Tuesday, June 09
Gamma Ray Burst (GRB) explosions can make kpc-size shells and holes in the interstellar media (ISM) of spiral galaxies if much of the energy heats the local gas to above 10^7 K.

Tornadoes are the most intense storms on the planet, and they’re never discussed without at least some mention of the term wind shear. Many of us sitting at home, though, have no idea what wind shear is, or if we do, how it affects tornado production.

I’ve been looking for a good, easy to read document outlining the latest climate science research and putting it in context for Copenhagen and I think I’ve found it.
Today in Sydney, the Climate Change Research Centre, a unit of the University of New South Wales, released The Copenhagen Diagnosis. It’s free to download... | <urn:uuid:6de73326-296f-4b7a-b8ba-84761d55c25e> | 2.78125 | 1,051 | Personal Blog | Science & Tech. | 41.26094 |
Classifying Critical Points
So let’s say we’ve got a critical point of a multivariable function . That is, a point where the differential vanishes. We want something like the second derivative test that might tell us more about the behavior of the function near that point, and to identify (some) local maxima and minima... | <urn:uuid:1470b6e0-0c2a-416e-a3f3-01bb7910efed> | 2.6875 | 931 | Academic Writing | Science & Tech. | 42.500034 |

Cryonics is the practice of preserving organisms, or at least their brains, for possible future revival by storing them at cryogenic temperatures where metabolism and decay are almost completely stopped.
An organism held in such a state (either frozen or vitrified) is said to be cryopr... | <urn:uuid:808b609d-c9b2-4043-aeea-548f59273c25> | 3.4375 | 2,487 | Knowledge Article | Science & Tech. | 20.021667 |

Last August, a 3,000-pound, eight-by-22 foot-robotic platform was launched into the Hudson River just north of Denning’s Point Peninsula in Beacon, N.Y.
On board the floating platform are state-of-the-art sensors that will provide continuous air and water monitoring including barometric pressure, wind speed and directi... | <urn:uuid:02237b71-3d97-43b4-b615-8779adad0180> | 3.03125 | 982 | Knowledge Article | Science & Tech. | 32.182778 |
I saw some tutorial pages on the internet about how to read files using C++
But I'm kind of confused because there isn't anything in code indicate where the file is from. So I think I need some explanation.

THE FRAGILE FAUNA OF ILLINOIS CAVES
by Steven J. Taylor and Donald W. Webb
Illinois has several hundred caves, many of them in nearly pristine condition.
This unique and fragile environment is home to a diverse array of creatures,
including organisms that are completely limited to the cave environment,
species that may... | <urn:uuid:df2ab0ff-bb86-415b-be4c-863c8014597f> | 3.78125 | 3,029 | Knowledge Article | Science & Tech. | 21.357917 |
There are many types of biomass—organic matter such as plants,
residue from agriculture and forestry, and the organic component of
municipal and industrial wastes—that can now be used to produce fuels,
chemicals, and power. Wood has been used to provide heat for thousands of
years. This flexibility has resulted in incr... | <urn:uuid:43454431-e724-4640-b136-09b9e018b7c6> | 3.828125 | 1,230 | Knowledge Article | Science & Tech. | 24.609679 |
Introductionfox, carnivorous mammal of the dog family, found throughout most of the Northern Hemisphere. It has a pointed face, short legs, long, thick fur, and a tail about one half to two thirds as long as the head and body, depending on the species. Solitary most of the year, foxes do not live in dens except in the ... | <urn:uuid:b06f1991-fec6-49bf-b55b-75db6d59f18d> | 3.5 | 382 | Knowledge Article | Science & Tech. | 50.583511 |
Here is a fun one,
There was a man who greatly enjoyed golf. He also could make a perfectly consistent swing. So out of curiosity he decided to challenge a mathematician. So first he brought the mathematician to a golf field, with his golf club, a tee, and a ball. He sets the ball on the tee, all ready to swing, and th... | <urn:uuid:070e6cdd-a083-43f2-9577-27e03e835620> | 2.765625 | 201 | Comment Section | Science & Tech. | 65.922443 |

Gamma ray bursts
are believed to be the most energetic phenomena in the universe.
In one second they can emit more than 100 times the energy that
the sun does throughout its entire 10 billion year life. This energy
output is short lived, however, and within days the burst has faded
forever beyond the reach of our teles... | <urn:uuid:41af5c95-84cb-4b31-990a-6fbb28055062> | 3.875 | 327 | Knowledge Article | Science & Tech. | 29.343642 |
